Fan without blades - innovation in modern technique. Silent Fan: Principle Action Aless Fan Drawings

A blind fan is a unique device that affects the imagination with its design. Such an aggregate does not have blades or a noticeable eye of rotating elements. Therefore, many are completely incomprehensible how this device works and how it moves the air masses. In fact, the principle of operation of such a fan is not so complicated. To do this, it is enough to study its design features.

The device works on the principle forced ventilationwhich was invented in ancient times in ancient times. So the ancient Egyptians were filmed to create comfortable conditions For pharaohs. They then did not understand all the scientific subtleties of lowering the temperature when flowing around the body with a gas stream, but this thermodynamic phenomenon was successfully used. Today, as a basis for fireless new products, the principle of operation of the turbine of modern jet aircraft is laid.

Silent fan can be two types:

1. Desktop.
2. Floor.

The outdoor embodiment is highlighted by large dimensions. In most cases, it is enough powerful fan. It is used to cool the room of considerable area. In many cases, such models of fans are supplied not only by the cooling function, but also heating.

Desktop models are highlighted by their compactness. Thanks to this, they can safely post on the table. With this fan, you can create a sufficiently comfortable environment in the workplace on a hot day in the absence of air conditioner. In addition, desktop models have a very stylish and unusual design. They may have a function of rotation to the left-right and remote control With the help of the console.

A number of models are provided with a device that is intended for air humidification. Such types of devices have a special reservoir in the fan housing where water is poured. There are also mini fans that can be taken with you on the road. Such devices can work from the cigarette lighter and used instead of air conditioner.

Device

The main elements of the fan without blades are the following parts:

1. Ring diffuser.
2. Engine.
3. High-speed turbine.
4. Base.

High-speed turbine in which the engine is mounted is installed at the base of the unit. Thanks to the operation of the turbine, air movement begins in the device. To reduce the level of the audio, the engine has a special hemgolc chamber, which catches and dishes noise. From this it seems that the fan is quite quiet.

In the base case, a lot of holes have been done to suck air. On the top of the case is an aerodynamic ring, which is equipped with a ring diffuser. He has a lot of holes through which air blows away. The ring itself may be the most of different shapes: rhombus, oval, circle, heart, and so on. It all depends on the designer thought of the designer of the manufacturer.

Operating principle

A blind fan operates with an electric motor. The air is absorbed by the turbine by means of small holes that are located at the bottom of the fan rack. Air mass after passing the turbine overlook the small hole in the center of the ring and then distributed over the contour. A air jet is created, which flows around the ring from the inside of its rim. The air masses cover the rim and on the streamlined surface are created inside the ring of the device negative pressure.

As a result, this leads to the fact that the air masses located near the fan are starting to be drawn into the center of the rings in the region of the discharged pressure. As a result, a powerful stream is created at the rings outlet, which can be gained up to 15-20 times. Such an aerodynamic effect makes it easy to move air masses and cool the room. The speed of the turbine unit can be controlled, so it is possible to set the required airflow speed. In this case, using a fan without blades, a sufficiently dense and comfortable stream of refreshing air masses is created. The work of the unnewable device itself and almost invisible.

Application

The scope of application of the specified fan is quite extensive - these are any municipal and public institutions, hospitals, sanatoriums, kindergartens, cottages, cottages, numerous offices, houses, apartments and so on. Except can be only bathrooms, saunas, bathrooms, pools. Despite the absence of external rotating parts, only adults should use it, you should not leave such devices included alone with young children.

In addition to the soft distribution of the air stream-free fan, it is capable of moisturize and even heat the air. However, this is only if the device has such functions. Such units in most cases are supplied with a control panel where you can set the necessary temperature and percentage of humidity. The regulation range is determined by a specific model. The cheapest devices usually have only cooling function. In expensive copies there may be even a function of purifying air from harmful impurities, for example, from cigarette smoke.

How to choose a fireless fan

Select a blind fan is not so simple. At the moment of time, the market of such equipment is replete with numerous variants of models from the most different manufacturers: This is Dyson, Orion, Supra, Bladeless and many others. There are cheap models from several thousand rubles and very expensive instances that are completed on the highest level and have many functions. Their cost can be up to 100 thousand rubles and higher.

• First of all, it should be proceeded from personal needs and financial opportunities.
• Before purchasing the device, you should familiarize yourself with its characteristics and find out the noise level. It is extreme important parameterAfter all, he will directly affect the comfort of use. The average noise range of similar devices is 40-60 decibels and above.
• Ring radius affects the efficiency of its use. For large premises It is recommended to choose devices with a larger ring.
• Power determines not only the stream force, but including the amount of electricity consumed and the level of the noise-published device. For an apartment or a small house, there is enough medium power fan. However, for a large office, you should pick up a fairly powerful device. For such premises, it is recommended to select units that per hour can drive about 250 cubic meters.
• For everybody, there is enough angle of rotation of the ring of 90 degrees, but if you wish, you can purchase a device with an angle of rotation to 360 degrees.
• Please note the quality of plastics and the absence of unpleasant odors.
• If you appreciate comfort, it is recommended not to suck and purchase a model that has a wide adjustment setting. The presence of a control panel with a clear system of buttons will make use more convenient.

Per last years A large number of new products appeared household appliances. Consumers are offered a diverse range of modern products and often in an updated design. The most popular can be called a boxless fan that works in economy mode And it is able to effectively refresh the room.

History of creation

A blindfold fan is very different from the product familiar to us. The first device appeared in 2009. Thanks to the Creator James Dyson. He devoted almost 30 years to work that was aimed at improving many types of household appliances. The English developer managed to come up with many unusual, useful and necessary inventions.

Many countries bought a patent for the production of these new products. Manufacturers attract not only the utility of devices, but also improved design, functionality Technique. When developing a special fan without blades, it was spent more than 4 years on the modeling of a ring capable of effectively passing the air flows, multiplying it repeatedly.

Cool a fireless fan from China !!!

The device quickly gained popularity and shortly after its appearance on the market began to sell similar fans. Now even there is more budget options from Chinese manufacturers.



Fan device

The work of this device is very similar to the effect of the engine of the jet aircraft. In its base, a high-speed turbine with a 40 kW engine is mounted, which are connected by a common shaft. Total two main parts (base, ring diffuser) are part of a fine fan. The principle of operation is based on the operation of the turbine, providing air intake in the device.

The instrument engine is equipped with a game Gamegolz camerawhich catches and dispels the noise of work. The device body has a plurality of holes, suction air. The device's ring diffuser was created according to the rules of aerodynamics. FROM inner On the surface there is a special slot. With its help in work zone Air discharge occurs.

The ring section has a drop view, since such a form is ideal, from the point of view of aerodynamics. It minimizes the resistance around itself, which does not allow turbulence.

Silent fan



Principle of operation

The technical principle of the turbine operation was applied in a blind fan. Placed at the base of the device, the turbine through the housing holes sucks the air outside and supplies it into the annular diffuser with a very narrow slit. His profile, specially adapted, works on an increase in pressure difference efficiency. This causes air to pushed out with force due to the aerodynamic effect.

In the resulting stream, the air surrounding the diffuser ring is immediately poured. Due to this, the air workflow increases 15-20 times at the fan without blades. The principle of operation of such a device is called the "air multiplier". This made it possible to get a safe and economical design.

It creates a dense monotonous stream, refreshing air masses. In the process of action, it functions unnecessary. The device is almost silent; It is very interesting to observe how the fan works without blades. Unlike ordinary device It does not create a draft and does not cause discomfort.



Main advantages

A relnamed device has many advantages compared to the usual fan. It is ideal for use in everyday life and office space. The devices differ in the following positive characteristics:



All these devices are equipped with remote control, which makes them very convenient during operation. The control panels are fixed to the housing to be comfortable to manage and not lose. Almost all the consoles are equipped with various options where you can select the desired mode of operation. Such a product helps in everyday life and at work without noise and discomfort getting a fresh air flow.




In addition, the fan has its own minuses: if you buy a more powerful device, then it makes noise during operation, which is very felt at high speed. Price u modern models High. If you buy cheaper counterparts from Chinese manufacturers, then they are distinguished by instability and creak.

Manufacturers of fine fans are constantly working on existing disadvantages. They periodically improve new models, given the reviews and offers of consumers.

Criterias of choice

"Multiplier air" differs not only by his positive characteristics, but also original design. With his bizarre form, he will decorate any room. By the installation method, they are divided into three types:

• outdoor;
• wall;
• desktop.

Wallows belong to stationary type devices, and two others to portable devices. Most often, manufacturers of such equipment provide for the installation of fans in two fastening options: on the wall and on the table. Bracket with dowels attached to them.

Consumers are now offered many models that are characterized by price and functional set. Before buying, it is necessary to pay attention to the characteristics of the device and its noise level during operation.

How to make a fireless fan with your own hands / How to make a DIY Safe Fan

The radius of the ringless fan ring affects the efficiency of operation. For large sizes, you should choose models with a larger ring. The amount of stream and electricity consumption will depend on the power of the "multiplier of air". For an apartment or a house of a small square, it is enough to buy an average power device. If you choose it for a large office, then you should buy an aggregate capable of driving a large amount of air.




It is recommended to pay attention to the body of the product so that it is high-quality and did not have unpleasant odor. For connoisseurs of comfort, it is desirable to give preference to models with a wide adjustment setting. Availability of a control panel with a convenient buttons system will make it easy and easy to control the household appliance.

Features of application



"Air multipliers" are now quite common. They are installed in homes and apartments, offices, hospitals and other institutions. They gently distribute air flows, but, in addition, can and moisturize, cool or warm the air. The setting range of the humidity level will depend on the model, so each user has the ability to choose for itself suitable option Products.

Heated and cooling is equipped only dear models. Options are offered with cleansing air from Chad, smoke and other harmful impurities. Now you can buy products from global brands that will perform the functions of real air conditioners.

Comments:

The 21st century brings their adjustments to all things, and even in those that seem to be changed.

In the 20th century, no one could imagine a blind fan, but such a system still works properly.

How the system works

The principle of work was taken from modern jet aircraft, whose turbines are no longer equipped with large valves, but still there is a turbine to create thrust. In the fan, such turbine is also available, but it is located in the leg, thanks to which it becomes imperceptible to the eye. Low level Noise, in turn, does not give it either.

If you look at the leg, then you can notice from all sides the presence of a large number of small holes. They serve in this case not only for cooling the system, but also for the fence of air. The average turbine is capable of driving about 20 l / s, which is quite a lot compared to fans with blades.

The speed of the transition of air from the working part into the distribution ring (the form can be different, but preferably without angles, so as not to create extra voltage) on average is 90 km / h. The distribution ring is made in a special way, due to which the exit air goes uniformly, creating a dense contour with a rarefied middle. If you pay attention to the cut, then the ring from the inside is hollow, except for the location of the slot (forgings for the formation of directional pressure).

At the outlet, the dense stream of air at a speed of 90 km / h is occurring with standing racking air, after which they compensate each other. Such interaction does not lead to a decrease in speed 2.5-3 times, but increases the volume of air to 20 times. Those. At the output, you can get 400 l / s at a speed of 30-36 km / h, while the movement will be strictly uniform.

The main advantage is safety, because For example, a child will no longer be able to touch the blades in motion, besides, they will not break from excessive voltage over time, which is quite often with plastic blades. You can wipe dust at any convenient moment, because Outside there are no metal conclusions and moving parts.

But there are also its cons, due to which the demand for devices has not yet bypassed a competitor:

1. Noise. Despite the fact that the turbine works almost silently, the exhausting stream of air creates a very strong hum.
2. Price policy. It is this factor that stops many lovers of unique things, and the price is several times higher than analogs with a propeller. This measure is temporary, because Technology is new, but when you master it with several serious corporations and a number of technical improvements, the price will be very different.

A fireless fan is modern devicewhich allows you to significantly reduce the risks, and its design is distinguished by the originality of attracting lovers of unusual.

Despite the high price, demand rises every day, and with it there is a variety and quality.

Traditional design ceiling fan Well known. Usually its blades with a whistle dissect air under the ceiling of the room, directing the air flow down. Being directly under the fan, you can enjoy a "easy breeze", and risk a POT

The traditional design of the ceiling fan is well known. Usually its blades with a whistle dissect air under the ceiling of the room, directing the air flow down. Being directly under the fan, you can enjoy a "easy breeze", and risk catching cold at the same time. But in the other places of the room, the flow action is practically not felt.

Inventor Nick Hinger (Nik Hiner), together with like-minded people from Exhale Fans offers a product that has listed listed and having an unusual innovative design.

In the new design, everything is supplied "from the legs on the head." No, the fan is still mounted under the ceiling of the room, but he has no whistling blades, and he does not blow the air flow, but pulls.

Instead of the blades, flat discs rotate, creating laminar (unidirectional) air flows moving along the surface of the ceiling and descending down to the floor along the walls of the room. As a result, the air, entering the fan from the bottom, evenly circulates throughout the room, stirring the temperature layers. Unlike a conventional blade fan, zones are eliminated in a room fully covered with laminar flow, the temperature in which is significantly different from the average value.

There are no rotating blades in the design, which predetermines a fundamentally smaller noise level during operation. In addition, a low noise electric motor is used to rotate the circles, which practically reduces the overall noise level to a minimum. Engine direct current It can rotate six different speeds, and is controlled by a wireless remote remote control. Definitely an indisputable advantage and the difference between the new fan from the blade fellow - appearance, perfectly inscribed in almost any interior.

The idea of \u200b\u200ba blinder ceiling fan came to the head of the hiner when he studied the design of the turbine Nikola Tesla. The first attempt to implement the unusual design of Hiner has taken in 2005. The following years left for the design adaptation and the manufacture of a whole series of prototypes before the inventor stopped at the current design.

To date, the fan is practically ready for production. For its launch, a certain amount is required that Hinger intends to spend on the development of packaging and buying raw materials.

Innovation is quite aggressive and annoyingly invaded our lives. Happy exception was the appearance on the market household appliances "Multiplier air". The imaginable imagination innovative device, a fan without blades, turned out to be unusually comfortable in use, efficient and economical, it easily won the sympathy of consumers.

Mysterious "air multiplier"

The fan without blades has become a bold step in the evolutionary path of climate-controlling household appliances. Honor of the invention belongs to the Englishman James Dyson, an engineer and industrialist, the author of a huge number of non-standard finds in solving everyday household problems.

Watching how the air of the air dryer gap captures the nearby air layers and involves them into their stream, it became interested in the idea of \u200b\u200bcreating a fireless fan. A long path of research and development, intellectual and financial costs was passed before the device appeared on the shelves and fascinated all his mysteriousness.

Now the range of household appliances stores is a whole assortment chain of light-blass fans. They differ in power, destination, design, there are models for every taste and wallet. Dyson's devices are up to 25,000 rubles, econnalogs of other firms - up to 2,500 rubles. There are desktop and outdoor structures, models with a diffuser in the form of a simple ring, in the shape of a heart, apple, rhombus, in the form of contours of funny children's toys. Models are equipped with a remote control.

Constructive signs

The fan without blades consists of two main parts:

• bases;
• ring diffuser.

In the base of the device, a high-speed turbine, equipped with a 40 W engine, with which has a shared shaft, is mounted. The turbine provides air movement in the device. The engine is equipped with a hemgolc chamber for trapping and dispersion of the engine noise. The base body of the apparatus has a plurality of air suction holes.

The annular diffuser of the fan is made according to the laws of aerodynamics. In the ring on the inner surface there is a special slot through which air injected in working surface. The cross section of the diffuser ring is a drop. This form is aerodynamically ideal in terms of the minimalization of resistance, turbulence zones are not formed around it.

Fan without blades: principle of work

The instrument uses the technological principle of the air turbine. Being at the base of the device, the turbine through the technological holes available in the base body sucks air from the outside and serves it through a narrow slot in the ring diffuser. A specially adapted profile of the ring-diffuser increases the efficiency of the pressure difference, as a result, the air is pushed with force due to the aerodynamic effect. Simultaneously in the resulting flow, the surrounding ring-diffuser air is involved, the workflow is increased by 1.5-2 dozen times.

Author unusual design Share it, which borrowed his idea in principle, the engine of jet aircraft and took advantage of it, creating a fan without blades. The principle of operation of this device is figuratively called the "air multiplier". As a result of innovative developments, an economical, safe and stylish design was created.

As a result, it turns out that if the paddle fan produces the vortex air flow and intermittently blows the workplace, delivering discomfort and draft, then the fan without blades creates a dense monotonous comfortable refreshment stream, its operation is unnewable, almost imperceptible.

Comparative advantages

Such fans:

• comfortable, as silent and do not create vibrations;
• hygienic, as they have a soft, pleasant stream of air and do not create drafts, easily clean, do not have parts accumulating dust;
• convenient, since there are sufficient volume of vertical and horizontal turn;
• stable, since the most severe part of the device is located in its foundation;
• safe, as they do not have outdoor moving parts representing a threat in the aspect of household and children's injuries;
• economical despite innovative advantageswhich the fan has without blades, the price of it is equivalent to the price of obsolete blade models;
• characterized by low power consumption, the device uses 98% less energy in comparison with bladed fans;
• aesthetic, as they have a modern design.

A blind fan is ideal for use in everyday life and in the office. Modern design, the comfort of air flow, silentness and lack of vibration, the possibility of remote control and the presence of a range of modes, efficiency, efficiency, hygienic and safety - all these characteristics successfully combines an innovative fan without blades. Reviews about his operation eloquently argue that it helps to make the owner's holiday full-fledged, and work is productive.
