Description

Vortex Tube

The present invention relates to a vortex tube, and more particularly, a coanda effect occurs due to a coda effect caused by a sheet spaced apart from the main housing and the vortex housing and a curved surface of the vortex housing in contact with the sheet. It is formed so that air through the inlet can be discharged to the heat radiating body to increase the cooling efficiency of the vortex tube through the forced cooling effect (air cooling) for the heat radiating body, and to generate the rotary airflow by the disk with a large number of radial grooves. As the conventional vortex generator is eliminated the need for multiple stages of processing, and the production cost is reduced by reducing the processing cost relates to a vortex tube.

In general, Vortex Tube is an inexpensive, reliable, and maintenance-free cooling device that is used as a solution to local cooling problems throughout the industry, and is a general compressed air (compressor) used in industrial sites. ) Is used as a driving energy source. In addition, the Vortex tube produces both cold and hot air streams with no mechanical drive at all, with a temperature control range of -46 ° C to + 127 ° C, a cold air flow control range of 28 SLPM to 4248 SLPM and maximum cooling capacity. Is 2571 Kcal / hr.

These vortex tubes are used for cooling electronic control and communication equipment, local cooling of machining processes (replacement of cutting oil), cooling of CCTV cameras installed in high temperature environments, solidification of molten metals, cooling of soldering or welding areas, cooling of large switching elements, high temperature It is used for the cooling of mechanical sealing parts and the production of performance test equipment for the creation of harsh low temperature environment.

Hereinafter, each component of the conventional vortex tube and the disadvantages of these components will be described with reference to the drawings.

1 is a cross-sectional view showing the structure of a conventional vortex tube.

As shown in FIG. 1, the conventional vortex tube is coupled to the main body 10 and the main body 10 in which the compressed air injection unit 15 is formed for the injection of compressed air, thereby generating cold and hot air. An air circulation tube 12 coupled to the generator 14 and the vortex generator 14; The cover 13 is coupled to the main body 10 and the control valve 16 and the cap 17 are coupled to the cover 13, is installed using a fixing nut in the cabinet, the cold air inside It is mainly used as a cabinet cooler to cool the electronic controller by spraying and to prevent impurities from penetrating the inside.

Conventional vortex tube is compressed air supplied from the inlet (15) is passed through the vortex generator 14 and the air circulation tube 12 and separated into cold and hot air control valve disposed on one side of the air circulation tube (12) It is discharged to the outside through the gap with (16), the cold air is injected through the injection hole in the structure of the heat is discharged smoothly the higher the efficiency.

However, since the air vortex tube 12 is overheated due to the heat released from the air circulation tube 12, the existing vortex tube may cause burns when the user contacts the air circulation tube 12, and thus it is difficult to use it as it is. By forming a separate cover 13 on the outer side of the air circulation tube 12, the user is prevented from directly contacting the air circulation tube 12 to solve the above problems. However, when a separate cover structure is covered on the outside of the air circulation tube 12 as described above, the direct heat discharged from the air circulation tube 12 is discharged to the outside through the discharge structure using the control valve 16, Heat generated from the surface of the air circulation tube 12 is not quickly discharged to the outside, and remains between the main body 10 and the air circulation tube 12 and the heat of the air circulation tube 12 is discharged. There is a problem in that it interferes with the cooling efficiency of the vortex tube.

In addition, in the case of the cabinet cooler using the conventional vortex tube as described above, the discharge structure using the control valve 16 is always kept open unless the user operates, which causes external dust, such as external dust, while the device is not operating. Since foreign matter may be introduced into the vortex tube and the cabinet through the open discharge structure, a separate shielding structure is required.

It is configured to enable the injection of cold air even when the loss of compressed air is minimized. It is a structure that generates a rotary airflow by a disk formed with a square groove, which eliminates the need for multiple stages of processing such as a conventional vortex generator, thereby providing a vortex tube that reduces production cost by reducing processing cost.

In the vortex tube according to the present invention, a coanda effect occurs due to a sheet spaced apart from the main housing and the vortex housing and a curved surface of the vortex housing in contact with the sheet, so that air through the compressed air inlet is Existing vortex generators are designed to be discharged to the heat dissipation body to increase the cooling efficiency of the vortex tube through the forced cooling effect (air cooling) on the heat dissipation body, and to generate the rotary airflow by the disks with a large number of radial grooves. This eliminates the need for multiple stages, such as providing a vortex tube that reduces production costs and reduces production costs.

In addition, due to the increase in the cooling efficiency, since it is possible to spray cold air without a structure for discharging the high-temperature air to the outside, the loss of the compressed air provides an effect.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings such that those skilled in the art may easily implement the present invention.

2 is a conceptual diagram illustrating the vortex theory applied to the vortex tube of the present invention.

First, the vortex theory will be described with reference to FIG. 2. When compressed air is supplied to the vortex tube, the air is injected perpendicularly to the longitudinal direction of the tube while contacting the inner side of the vortex rotation chamber through the nozzle. The jetted air forms a whirlwind-like vortex that moves around the inner wall of the tube and travels toward the end of the tube. At this time, when the valve attached to the end of the tube is opened a little, the heated air is discharged to some outside, and the remaining air that is not discharged again reverses while forming a small vortex along the center of the tube. The second internally formed vortex loses heat and is cooled and discharged to the opposite end of the tube.

The internal vortex loses heat because the air that swirls the inner wall of the tube flows up to either side of the tube in a high temperature state and some of it is vortexed in the same direction inside the hot vortex, As it enters the state and flows down the opposite side of the tube, the two vortices rotate in the same direction and at the same speed.

However, due to the law of conservation of angular momentum (rotational momentum) of the laws of mechanics, the gas that rotates the outside of the large rotational radius flows into the narrower rotational radius and the rotational speed should be faster. The rotational angular velocity of the air does not accelerate and is the same as when traveling around the outside because the air inside has lost its angular momentum. The air inside the lost angular cloud loses energy, resulting in a drop in temperature. The energy lost by the air inside is transferred to the air rotating outside, and the air rotating outside becomes hot.

Figure 3 is a perspective view showing an exploded state of the vortex tube according to an embodiment of the present invention, Figure 4 is a view showing the inner cross section of the vortex tube according to an embodiment of the present invention.

As shown in FIGS. 3 to 4, the vortex tube A according to the present invention includes a main housing 100, a vortex generator 200 inserted corresponding to the main housing 100, and the vortex generator 200. The rotational body is interposed between the heat dissipation body 300 coupled to the other side, the seat 400 and the vortex generator 200 and the heat dissipation body 300 spaced apart from the main housing 100 and the vortex generator 200. It is formed by separating the disk 500 to generate.

The main housing 100 is formed by penetrating the compressed air inlet 101 for the external compressed air injection perpendicular to the longitudinal direction of the main housing 100, and circulating the compressed air in the circular air inlet 101 A portion 102 is formed, and the generator insertion hole 103 formed to have a diameter smaller than the compressed air circulation portion 102 is formed through one side of the compressed air circulation portion.

In addition, the compressed air inlet 101 is screwed to the coupling hole (not shown) for the connection of pipes and pipes for the inlet of compressed air, the coupling hole (not shown) is stably fixed so that the pipes and pipes do not fall out This is preferred.

In addition, the cold air discharge unit 110 is provided at one side of the generator insertion hole 103 of the main housing 100, and the coupling between the main housing 100 and the cold air discharge unit 110 is coupled using a screw, and In addition to the method of combining using it turns out that can be combined in various ways.

On the other hand, the cold air discharge unit 110 is made of a low thermal conductivity material is thermally insulated from cold to prevent the temperature of the surface of the cold air discharge unit 110 falls below the dew point temperature.

The vortex generator 200 is divided into a vortex housing 210 and a vortex member 220.

One side of the vortex housing 210 is inserted corresponding to the generator insertion hole 103 of the main housing 100, the compressed air inlet 211 is penetrated perpendicularly to the longitudinal direction of the vortex housing 100 to the outside The through-hole 212 is formed in the longitudinal direction through the inlet of the compressed air entry portion 211.

One end of the vortex member 220 has the same outer diameter so as to be inserted into the through hole 212 and the other end has a smaller inner diameter than the end inserted into the through hole 212 and the air through the compressed air inlet 211. The air circulation unit 221 is formed to circulate, and the cold air discharge hole 222 penetrated in the longitudinal direction of the vortex member 220 is formed therein.

The vortex generator 200 configured as described above is configured by inserting the vortex member 220 into the through-hole 212 of the vortex housing 210, in which the insertion groove 223 is formed on the outer circumferential surface of the vortex member 220. A rubber ring 224 is inserted into the insertion groove 223, and the rubber ring 224 is configured to prevent leakage of compressed air when the vortex member 220 is inserted into the through hole 212. to be.

In addition, a curved surface 213 is formed on the other side of the vortex housing 210 that is not inserted into the generator insertion hole 103.

Here, the reason why the curved surface 213 is formed in the vortex housing 210 is that the air tends to adsorb to the surface when the curved surface (; 213) flows due to the Coanda effect, which will be described later. It is for guiding and discharging air in the direction (300).

The Coanda effect, in which the fluid flows in close contact with the curved surface, knows what direction the fluid will flow in the forward direction. If the bend flows, the fluid flows along the curve. As it flows, the fluid flows toward the least energy-consuming one, called the Coanda effect. In other words, the fluid accurately identifies the path through which it flows and flows accordingly.

When compressed air injected from the main housing 100 and the vortex housing 210 flows along the curved surface 213 formed in the vortex housing 210 due to the Coanda effect, the air flows at high speed. The air is drawn together and the effect is to be injected together, and thus the cooling of the heat dissipating body 300 can be made smoothly only by discharging a small amount of compressed air.

On the other hand, noise is generated due to the high pressure cold air discharged through the cold air discharge hole 222 of the vortex member 220, which is a silencer 230 in the space between the cold air discharge hole 222 and the cold air discharge unit 110. Is solved by adding In addition, the silencer 230 is a porous form in which the metal particles are sintered and has excellent durability as compared to a filter silencer using a conventional styrofoam or the like. That is, in the case of the conventional silencer, the cold air injection unit is lowered from minus 40 degrees to minus 50, causing shrinkage and expansion according to temperature change, and even if it is not damaged, it is difficult to properly perform the role as a silencer. By sintering the particles, the inside is made porous to minimize deformation and ensure durability.

Particularly, in the case of the silencer 230 coupled to the cold air discharge hole 222 side, the silencer 230 may be pushed out due to the cold air injected at a high speed, and thus may fail to function. (Not shown) to form a female screw (not shown) in the cold air discharge hole 222 of the vortex member 200 to which the silencer 230 is coupled to be screwed to prevent the silencer 230 from being separated. .

Since the silencer 230 for reducing noise is already used a lot in the related art, a detailed description of the internal structure and operation thereof will be omitted.

The heat dissipation body 300 has an insertion part 301 inserted into the through hole 212 of the vortex housing 210, and a circular vortex circulation part 302 is inserted into the insertion part in the longitudinal direction of the heat dissipation body. It is formed through. On the other hand, the heat radiation body 300 is preferably formed of a high thermal conductivity aluminum material.

In addition, a plurality of cooling fins 303 are repeatedly formed outside the heat dissipation body 300, and the heat dissipation body 300 on which the cooling fins 303 are formed is processed by compression molding in the longitudinal direction.

Meanwhile, the reason why the cooling fin 303 is formed is to increase the heat dissipation effect as the area in contact with the air by the cooling fin 303 increases, thereby improving the performance of the vortex tube A, and directly contacting the body. By minimizing the area, if the vortex tube (A) is overheated, the possibility of burns is reduced.

Since the heat dissipation function is improved by the cooling fin 303, the heat of the vortex tube A is discharged faster than the conventional structure, so that the performance of the vortex tube A is increased. The performance can be improved since heat (energy) can be taken out of the backflow of the airflow. In addition, the entire heat dissipation body 300 (parts in contact with the inner air flow and the unevenness of the outside) is integrally formed, so that the heat conduction is rapidly performed, thereby making the most of the heat dissipation effect by the cooling fin 303.

On the other hand, the other side of the vortex circulation portion 302 of the heat dissipation body 300 is provided with a cap 310 for sealing the vortex circulation portion 302.

Existing general vortex tube structure to discharge the heat inside the vortex tube in the form of discharging the hot air to the outside in the air circulating inside the tube for the discharge of cold air, but in the case of the present invention As forced cooling of the cooling body is achieved by a cooling structure using a Coanda effect, the cooling of the high temperature air inside the vortex tube is smoothly performed, thereby minimizing the amount of compressed air that is wasted.

The seat 400 is interposed between the main housing 100 and the vortex housing 210 to allow air through the compressed air inlet 101 to be discharged to the heat dissipation body 300, and the main housing 100 and the main housing 100. The vortex housing 210 is configured to space apart. This, the air should be discharged to the heat dissipation body 300 along the curved surface of the vortex housing 210, the main housing and the 100 vortex housing 210 when the airtight each other because the passage for the discharge of air is missing The main housing 100 and the vortex housing 210 are spaced apart from each other to allow passage of the main housing 100 and the vortex housing 210.

More specifically, both surfaces of the sheet 400 are formed in a ring shape in contact with the main housing 100 and the vortex housing 210, respectively, to maintain the gap. Specifically, the inside is penetrated to be inserted into the vortex housing 210, and a plurality of protrusions 401 are repeatedly formed along the ring-shaped outer circumferential surface to maintain the spacing.

In addition, an air passage 402 is formed between the plurality of protrusions 401 of the seat 400, which discharges air through the compressed air inlet 101 of the main housing 100 to the heat dissipation body 300 on the other side. To do so, it is formed in a structure for guiding the flow of air.

On the other hand, the sheet 400 is a plurality of protrusions 401 are repeatedly formed in the ring-shaped inner peripheral surface formed through, the air passage 402 may be formed between the protrusions 401.

The disc 500 is configured to generate a rotary airflow interposed between the vortex generator 200 and the heat dissipation body 300, and more specifically, the air circulation hole 501 is formed through the center of the disc 500. A plurality of radial grooves 502 are repeatedly formed above the air circulation hole 501.

On the other hand, the upper end is located on the outer peripheral surface of the radial groove 502, the lower end adjacent to the air circulation hole 501 is formed to be incident in the internal tangential direction of the air circulation hole 501 is a configuration for forming a strong vortex. .

Here, the rotary airflow may be generated only when the air enters the upper end of the radial groove 502, which is not only generated when the air enters the lower end of the radial groove, but also the vortex circulation part of the heat dissipation body 300. It is not possible to guide the air to 302. Accordingly, the lower end of the radial groove 502 is in close contact with the other side of the vortex member 220 so that no air is injected into the lower end, and air is injected into the upper end of the radial groove 502 to cause a vortex.

Therefore, the vortex generator 200 is inserted into the generator insertion hole 103 of the main housing 100, the sheet 400 is inserted to space the main housing 100 and the vortex generator 200, and the vortex generator Inserting the disc 500, the radial groove 502 is formed in the through hole 212 of the 200, coupled to the insertion portion of the heat dissipation body 300 to the through hole 212, the disc 500 is inserted The vortex tube A of the present invention is constructed.

Various components are included in addition to the above-described configuration, but since a general function is applied to components for parts not directly related to the present invention, description thereof will be omitted.

In the above description has been described the general configuration of the present invention, in the following description will be described in detail the operation of the present invention with reference to the drawings.

5 is a cross-sectional view showing an internal operating state of the vortex tube according to an embodiment of the present invention.

As shown in FIG. 5, compressed air having a pressure of 5.5 to 6.9 atm is introduced into the compressed air circulation unit 102 through the compressed air inlet 101 of the vortex tube A, and the compressed air circulation unit 102 is shown. Air introduced into the curved surface 213 of the vortex housing 210 or the compressed air inlet 211 of the vortex housing 210, the compressed air introduced into the compressed air inlet 212, the vortex member Through the air circulation portion 221 of the 220 is inserted into the radial groove 502 of the disc 500, a rotary airflow is formed, the rotary airflow has a rotation speed of up to 1 million RPM, rotates, injected compressed air Due to the pressure of the air flow occurs to move to the outside of the vortex generator 200, wherein the vortex circulation portion 302 of the heat dissipation body 300 of the rear side compared to the front cold air discharge hole 222 of the vortex generator 200 Rotational force of the air stream (with a force applied to the outside by centrifugal force) ) Causes the airflow to move backwards rather than forwards.

The forward air flow moved as described above moves through the extended vortex circulation unit 302 and collides with the cap 310 blocking the vortex circulation unit 302. The reverse airflow reversed by the collision is the vortex circulation unit 302. ) Moves in the reverse direction to the vortex generator 200.

And, the air flow moving in the reverse direction is made to move through the tunnel-shaped space formed inside the forward air flow generated from the vortex generator 200, the radius of the reverse air flow is reduced by that, the rotation force is increased as the radius is smaller (The law of conservation of angular momentum).

In addition, a direct contact between the reverse air flow and the forward air flow occurs, the rotation speed between each other is a constant phenomenon occurs, as a result of which the energy of the reverse air flow is transferred to the forward air flow, the temperature of the forward air flow rises, Reverse airflow causes the temperature to drop.

However, the vortex circulation unit 302 is discharged to the outside even if the temperature difference occurs between the forward air of the outside and the reverse air of the inner side as the transfer of energy as described above in the state blocked by the cap 310 Since it is not discharged to the outside through the cold air discharge hole 222 in front of the vortex generator 200 in the end with the reverse air flow, the effect of lowering the actual temperature is lost.

In the conventional vortex tube, when a separate control valve coupled to the cap blocking the vortex circulation part 302 is opened during the circulation of the air flow as described above, a high temperature forward airflow is caused to be discharged to the outside. The amount of hot air flowing back by the amount of air flow is reduced so that the cooled air can be discharged, but the amount of cold air generated decreases compared to the amount of air introduced as the air discharged to the outside increases, so that it is appropriately controlled through the control valve. Coordination will be used.

However, in the case of the vortex tube according to the present invention, a part of the air introduced into the compressed air circulation unit 102 passes through the air circulation unit 402 of the seat 400 along the curved surface 213 of the vortex housing 210. Moving in the direction of the heat dissipation body 300 to cool a plurality of cooling fins 303 of the heat dissipation body 300, according to the high temperature of rotating the outside of the air circulation portion 402 of the vortex tube (A) Since the air temperature is lowered, since it is possible to inject the normal cold air without separately discharging the high-temperature air to the outside, the compressed compressed air is minimized.

The vortex tube (A) configured as described above is used for cooling components for air conditioning refrigerant piping joined through automatic brazing equipment, or for cooling to prevent deformation of a product produced by automotive blow molding technique, and requires local cooling. Can be installed and used anywhere.

As mentioned above, although this invention was demonstrated in detail using the preferable embodiment, the scope of the present invention is not limited to a specific embodiment and should be interpreted by the attached claim. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.
