Abstract

The invention relates to a fan comprising an incorporated cooler, in which a coolant can be embodied in the form of a gas, for example freon. The cooling element of the incorporated cooler is combined with the fan blades, i.e. it means that the element is mounted directly on the blade or the blades are embodied in the form of a cooling elements. The cooling element can be embodied in the form of an evaporator, which is fixable to the fan blades, or the blades can be embodied in the form of an evaporator. The body of a cold producer, for example a compressor, is mechanically connected to the fan blades and to the shaft of a motor thereof in such a way that it rotates therewith, wherein the shaft of the compressor is rigidly fixed. In the case of a magnetic incorporated cooler, the cold producer is embodied in the form of magnets, and a ferromagnetic material, coaxially to which said magnets are arranged, is embodied in the form of a ferromagnetic disc, from which cold is transmitted to the fan blades directly or through a heat exchanger. In such a case the blades are used as the cooling element of the magnetic cooler.

Description

FAN

The claimed device relates to fans, which can find application both in production and in everyday life for cooling a room.

Fans are widely known for mixing air in a room and cooling a person in it by increasing the force of evaporation of liquid from his body.

A disadvantage of the known devices is the low cooling capacity due to the lack of a cooling source.

As a result of a patent search, it was not possible to find an analog or prototype of the claimed device.

The aim of the proposed invention is to provide a fan of the simplest design with a built-in cooling source.

This goal is achieved by installing a cooling element on the fan blades or by making them in the form of a cooling element of a refrigerator built into the fan, the cold producer of which is technologically connected with these blades with the possibility of joint rotation, while the temperature of the blades in working condition is lower than the ambient temperature, such as air or water.

The fan is illustrated by the following drawings:

The fan contains a compressor 1, on the case of which there are blades 2, on which cooling elements are installed or in which evaporators 3 are installed, in this case the blades 2 are considered hollow, the cavities 4 of which are filled with a coolant, for example freon, while the evaporators 3 can be shaped match the shape of the blades. In this example, we can assume that the blades 2 are aligned with the evaporator 3, i.e. the blades 2 are combined with the cooling element of the refrigerator built into the fan. It can also be considered that the evaporators 3 are made in the form of blades 2, more generally the cooling elements are made in the form of blades 2, or the blades 2 are made in the form of evaporators 3, more generally the blades 2 are made in the form of cooling elements. But all these expressions characterizing the connection of the blades 2 and cooling elements can be combined with one expression, namely, the blades 2 are combined with cooling elements integrated in the refrigerator fan, for example, with an evaporator, regardless of whether these elements, for example, evaporators 3, are installed on the blades 2 or in them. The compressor 1 output is connected by a pipe 5 to a condenser 6, the output of which by a pipe 7 is connected to a filter 9. A filter 10 is mounted on the filter housing 9, a shaft 10, for example, by welding, coaxially to the shaft 11 of a motor 12, for example, an electric motor mounted on a tripod 13, and on a guide 14 of the engine 12, a sleeve 15 is pressed in with a protective grill 17 mounted on it, for example by welding, for example 17. A sleeve 18 is made in the grill 17, which is mounted, for example, by welding, coaxially to the shaft 19 of the compressor 1, while the shaft 19 is rigidly installed in this sleeve 18, for example using press-fit.

The outlet of the filter 9 through the capillary, throttling tubes 20 is connected to the cavities 4 of the evaporator 3, for example, from the butt of the blades 2, and from the opposite side, for example, from the upper edge of the blades 2, these cavities 4 are connected by tubes 21, for example, installed from the leading edge of the blades 2 or passing in them, with the input of compressor 1. Thus, a closed system of the refrigerator is realized. (Fig. 1/7) The evaporator 3 can be mounted directly on the blades 2, for example by welding, if the blades 2 are made of metal, or with glue if they are made plastic-free. (Fig. 2/7)

When performing the evaporators 3 in the blades 2, and more precisely when performing the evaporators 3 in the form of a blade 2, or the blades 2 are made in the form of evaporators, their surface may contain corrugations 22. (Fig. Z / 7)

At the output of filter 9, an output collector 23 can be made to which tubes 20 are connected, on which chokes 24 are mounted, and an input collector 25 connected to tubes 21 can be installed at the input of compressor 1 (Fig. 4/7)

A magnetic refrigerator can be integrated into the fan, for example, a ferromagnetic disk 26 on which the blades 2 are fixed, can be installed between the permanent magnets 27 and 28, which are secured on the shaft 11, between the emphasis 29 of this shaft and the washers 30, using a fixing bolt 31, passing through magnets 27 and 28 having a cylindrical shape with a central passage hole and a hole made in the disk 26, while the bolt 31 is threadedly connected to the hole 32 made in the shaft 11. Cooling can be mechanically connected to the disk 26 any elements 33 or made as a single unit of the same material as the disk 26, finally the blades 2 themselves and are made of the same material as the disk 26, for a single unit with it and acting as a cooler. But the cooling elements 33 or blades 2 can be made of another material that conducts cold well, by contact or by welding connected to the disk 26. (Fig. 5/7)

The magnets 27 and 28 can be fixed motionless on a tripod 34, while they can be made in the form of electromagnets mounted on a guide 14, for example, pressed onto it, while the tripod is made of non-magnetic materials, and the magnets are pressed into its holes 35, axially to the disk 26 on the one hand, fixed in this example on the sleeve 36, for example with glue, on which the blades 2 are attached, for example by welding or in a single unit with it. On the sleeve 26 mounted blades 1, for example, by welding or in a single unit with him. The cooling elements 33 are mechanically, for example tangentially connected to the disk 26 or are integral with it, or the blades 2 themselves are made in the form of cooling elements. (Fig. 6 and Fig. 7/7)

On the guide 14 can be installed fixed vortex air flow stationary blades 37, for example by welding, axially to the disk 26. (Fig.7 / 7). Holes 38 may be provided in sleeve 36, in which are installed movable magnets 39 and 40, while the axes of the magnets 27 and 28 are located on the rotation path of the movable magnets 39 and 4O. (Fig. 8/7)

Magnets 39 and 40 can be made in the form of electromagnets. In this case, the shaft 11 is hollow, through the cavity 41 of which there are wires 42 connecting the electromagnets 39 and 40 to the windings 43 of the phase rotor 44, i.e. the motor 12 is made with a phase rotor, in the winding circuit 43 of which the windings of the magnets 39 and 4O are connected in series. (Fig. 9/7)

The fan can be made in vertical design, for example, its engine 12 can be locked on a frame 45 mounted on the ceiling 46, for example on the ceiling, and the sleeve 18, in which the shaft 19 of the compressor 1 is fixed, is mounted on the frame 45 using fittings 47, for example by welding, while the reinforcement 47 can act as a protective grating. (Fig. LO / 7)

The filter 9 can be installed in front of the condenser 6, from the end of which tubes 20 depart. In this case, the pipe 5 is connected to the input of the filter 8, and the shaft 10 is mounted on the housing of the condenser 6, while the tubes 20 are connected to the condensate outlet - pa 6. (Fig. .ll / 7)

The magnetic refrigerator built into the fan can be made in the style of the refrigerator of the future, namely, the permanent magnet 48 is connected through the magnetic circuit 49 through the working gap 50 to the ferromagnetic hollow disk 51 through which it passes, while the disk can be filled with magnetic substance, for example, rare earth parash gadolinium metal (Gd), while the disk 51 is mounted on the sleeve 52, which, in turn, is mounted, for example, pressed onto the shaft 11. The ends of the heat exchangers 53 made of well heat-generating material, for example, from copper or its alloys, otherwise they can be called cold or cold collectors, or cold conductors, the beginning of which are installed on the blades 2, made for example of metal, for example, by soldering, the blades 2 and heat exchangers 53 can be made for a single unit of cermets. On the opposite side of the disk 51, axially to it, relative to the heat exchangers 53, in the vicinity of the gap 50, heat exchangers 54 are made of well-conducting material, which can be called heat sinks or heat sinks or heat pipes. In the tripod 34, holes 55 are made, in which heat exchangers 54 are installed, for example, pressed in, at the end of which radiators 56 are installed. Magnet 48 and magnetic circuit 49 can generally be called a source of a magnetic field, which can be set to the disk 51 severally, but for operability at least one source of magnetic field is sufficient for a fan. The heat exchangers 53 and 54 may have a different shape, for example, in the form of vertical rods of round or rectangular shape. Heat exchangers 53, in order to increase the area of heat exchange, may have at the beginning, or at their base, thrust bearings 57, made, for example, in one piece with heat exchangers installed on the disk 51, which cover most of the upper surface of this disk. In this example, the fan is made conditionally up by the blades 2, in fact, it can be installed horizontally, or down by the blades 2. (Fig.l2 / 7)

The heat exchanger 53 can be made uniform for the blades 2, have, for example, the shape of a cylinder, and be connected to all blades 2, no matter how many they are made on the fan, and the disk 51. Therefore, in general, for an example of execution of the claimed device, the expression at least one heat exchanger 53 connecting the blades 2 with the disk 51. In this case, we can assume that the heat exchanger 53 is made movable. (Fig.lZ / 7)

The base of the heat exchangers 53 can be rigidly connected to the upper part of the cylinder body 51, for example by welding or be made with it as a whole. In this case, the functions of the thrust bearings 57 are performed by the upper part of the cylinder body 51. (Fig. 14/7)

The most cost-effective can be considered the direct installation of the blades 2 on the disk 50, for example, as a whole with a part of the body of the disk 50 or with its entire body, in this case, the blades 2 combine the role of mobile heat exchangers.

This can be achieved by installing the disk 50 on the shaft 11 through the sleeve 58 mounted on the disk 50, for example, by welding and having a threaded connection with the bolt 59 of the shaft component 11. And the component part of the blades 2 can be considered its butt component 60, which can simply be name the butt of the blade 2, which may have a hollow cylindrical shape, have a conical shape, or be solid. This knotted component 60, or the butt of the shovels 2, can be made integrally with these shovels and mounted directly on at least part of the body of the disk 50 by welding or made with it in a single unit. In this case, we can assume that the blades 2 are installed directly on the disk 5O. (Fig.l5 / 7)

The disk 50 may be made of a solid magnetic material, for example of a ferromagnet, and also be an integral part of the blades 2 or connected to them or with their butt component 60, or butt, with glue, welding or soldering. (Fig.lb / 7)

Each blade 2 can have a butt component 60, or a butt, for example, having the form of a continuous half cylinder, which, when installed on the disk 50, can be connected. When using three blades 2, then the butt components 60, or the butt, having the shape of a third of the cylinder will be three, and T.D. (FIG.17 / 7)

Komlevy components 60, or komli, can be executed FLOYS. (FIG. 18/7)

The blades 2 can have a common butt component 60, or the butt, for example, made in the form of a continuous cylinder, to which a certain number of blades 2 are attached, for example by welding, soldering or glue, or made at the same time at the time of melting or pressing. (Fig.l9 / 7)

The common butt component 60, or butt, can be made hollow. (Fig.20 / 7)

Considering that the coldest zone on the disk 51 is located on the opposite side of the shaft 11 with respect to the gap 50, it is desirable to remove the cold on the blades 2 from this zone for profitability, therefore, a rack 61, for example, of an L-shaped shape, can be mounted on a tripod 34 at the end of which at least one heat exchanger 62 is fixed, one end of which is located axially to the disk 51, and its opposite end is located axially to the sleeve 36, which for this example is made of a sufficiently large diameter. More generally, heat exchangers 62 are located near the cooled portion of the disk 51. (Fig. 21/7)

Thus, when using a gas refrigerator integrated in the fan, for example, a freon refrigerator, the producer of cold is compressor 1, and its cooling element is blades 2 on which evaporators 3 are mounted, or evaporators 3 are made in the form of blades 2, or in general evaporators 3 are combined with blades 2, while the compressor housing 1 during operation of the compressor rotates with these blades, and its shaft 19 is fixed on the fixed part of the fan housing, which is the protective grill 16.

When using a magnetic refrigerator built into the fan, the manufacturer of the cold is at least one magnet, for example, magnet 48, and the ferromagnet which is magnetically mounted to this magnet, and the cooling element are blades 2 that are connected to the ferromagnet either directly or through heat exchangers.

The fan operates as follows: When the fan is started, the rotation of its shaft 11 is transmitted through the coupling On the filter 7, the condenser 6, the compressor 1 and the blades 2 kinematically connected with it. Considering that the compressor shaft 19 is stationary and its casing rotates, the compressor begins to suck in gas, such as freon gas, from the evaporator 3, made, for example, in the form of blades, compresses it, transferring it to a liquid state with heat evolution and, for example, pushes it through a filter 9 into a condenser 6, in which it cools down and again flows through the capillary tubes 20 to the evaporators 3, t .e. into the hollow blades 2, in which the freon passes into a gaseous state, it is rapidly cooled, taking heat from the walls of the blades 2, which act as evaporators 3. If the evaporator 3 is combined with the blades 2 by installing it on these blades, then it transfers cold to the blades 2, which cool the environment.

As for the use of a magnetic refrigerator built into the fan, the simplest version of its implementation is the installation of two magnets 27 and 28 oxy-to the ferromagnetic disk 26, in the contact zone of the disk 26 with these magnets the ferromagnetic material is charged with a certain sign, and in the adjacent region of the ferromagnetic disk this material charged with the opposite sign and cooled, this cooling is transferred to the blades 2, directly or through the cooling element 33. But this example is not very efficient, but for everyday life A new fan is sufficient.

A more effective example of a built-in fan is the device depicted in figure 2., which uses the magnetocaloric effect. When the gadolinium enters the working gap 50 of the magnetic circuit 49 it is charged with a certain sign and heated, after exiting this gap the gadolinium is charged with the opposite sign and cooled, for faster cooling it is used a heat exchanger 54 installed at or behind the gap 50, which removes heat from the disk 51 to radiator 56. And from the cooled part of the disk 51 through heat exchangers 53, 62 or through the butt part 60 of the blades 2, the cold is transferred to these blades, which rotate and transfer it to the surrounding medium, which can be like a gas and a liquid, wherein the fan blade 2 may perform functions stirrer. Additional materials:

The fan can be used to cool an internal combustion engine, for example, for a car or airplane engine. This is illustrated by the drawings:

FIG. 22/7 - An example of installing a fan on a car.

FIG. 23/7 - An example of a fan drive.

In these examples, the tripod 13 is mounted on the front of the car body 61 with a hood 62, wheels 63, a bumper 64, and the sleeve 18 with the shaft 19 of the compressor 1 fixed in it is mounted on a tripod 65 also mounted on the front of the car body 61, for example, on its base . (Fig. 22/7).

The fan drive may consist of a sleeve 66 mounted on a tripod 67 mounted on a car body, in which is mounted, for example, through a bearing, rotatable, the drive shaft 68 connected to the coupling Na, and kinematically, for example via a belt drive 69, connected with drive shaft of the car, for example with a cord shaft 70, (Fir.23 / 7)

The principle of operation of the fan in these examples coincides with the principle of its operation described in the previous examples.

Additional materials:

FIG. 25/7 - An example of installing a fan on a non-contact cooling tower.

FIG. 26/7 - An example of installing a fan in a water tank.

FIG. 27/7 - An example of installing a fan on a contactless cooling tower.

The evaporator 6 can be installed in relation to the compressor 1 to the filter 9. (Fig.24 / 7)

The claimed fan can be installed on a non-contact cooling tower instead of a conventional fan installed but constructive data on it, for cooling a liquid, such as water. For example, a cooling tower 71 isolated from the spraying medium is made, comprising, for example, an upper collector 72 and a lower collector 73 interconnected by nozzles 74, for example, having a corrugated surface with corrugations 75. The lower collector 73 is connected by a pipe 76 to the inlet of the pump 77, to the same pipe 76 a feed line 78 may be provided. The output of the pump 77 is connected to a refrigerated device 79, for example, to a compressor or to a condenser of a refrigeration unit.

The output of the cooled device 79 by a pipe 80 is connected to the upper collector 74. Thus, a recycled water supply system is implemented. Microcooling 71 can be mounted on the frame 81. The base of the tripod 65, on which the sleeve 18 with the shaft 19 of the compressor 1 pressed into it, can also be mounted on the frame 81, for example by welding. The blades 2 are located axially to the nozzles 74 and collectors 72 and 73. (Fig.25 / 7)

The inventive fan can also cool a liquid, for example water, and in a contact way, for example, its blades 2 can be in a tank 82 filled with liquid 83, placed in it or on it. The frame 45, on which the fan is mounted, can be mounted on the housing of the tank 82, for example, by means of a welding. (Fig. 26/7)

To cool a non-contact cooling tower, a fan with a built-in magnetic refrigerator can be used, which, like a gas fan, can be mounted on the frame 81 of a cooling tower 71 through the engine 12 and a tripod 13. (Fig. 27/7)

When using a fan to cool a non-contact cooling tower, when the cooled blades 2 rotate, the air cooled by them penetrates the cooling tower 71, cooling the liquid in the nozzles 74 and collectors 72 and 73, of which the cooled water is pumped to the inlet of the cooled device through a pipe 77, cooling it and Having warmed up the water itself through the pipeline 80, it is again supplied to the cooling tower 71 for cooling.

With the contact method of cooling the liquid, cold blades 2 cool the liquid 83 directly in the tank 82.
