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 perspective view showing a coupling state of the vortex tube of Figure 3, Figure 5 according to an embodiment of the present invention 6 is a view illustrating an internal cross section of the vortex tube, and FIG. 6 is a view illustrating a side surface of a main body according to an exemplary embodiment of the present invention.

As shown in FIGS. 3 to 6, the vortex tube A according to the present invention is largely divided into a main body 100, a vortex generator 200, a control valve 300, and the like.

The main body 100 is provided with a fastening portion 101 having a threaded portion 101a formed at one side thereof, and a cap fixing portion 102 having a threaded portion 102a formed at the other side thereof, and having a compressed air inlet for injecting external compressed air ( 103 is formed perpendicularly to the longitudinal direction of the main body 100, a circular generator seating portion 104 is formed inside the compressed air inlet 103, the generator seating portion 104 and the cap A circular air circulation part 105 is formed between the government parts 102 in the longitudinal direction of the main body 100. On the other hand, the main body 100 is preferably formed of a high thermal conductivity aluminum material.

In addition, the compressed air inlet 103 is screwed to the coupling hole 103a for connecting the pipes and pipes for the inlet of compressed air, the coupling hole 103a is preferably fixed so that the pipes and pipes do not fall out. Do.

In addition, a plurality of air discharge grooves 106 in which the screw portion 101a is partially removed are formed in the fastening portion 101 of the main body 100, and a female thread 107 is formed inside the fastening portion 101. The cold air discharging unit 110 having the male thread 111 corresponding to the female screw 107 is screwed together, and the cold air discharging unit 110 is made of a material having a low thermal conductivity and thermally insulated from the cold air to discharge the cold air. The temperature of the surface of the unit 110 is prevented from falling below the dew point temperature.

In addition, as shown in FIG. 6, the cooling groove 120 and the cooling fin 130 are repeatedly formed to the outside of the main body 100, which is formed by repeating the cooling groove 120 and the cooling fin 130. It is formed by extrusion molding in the direction.

In addition, the cooling fin 130 is formed with a screw hole 131 in the longitudinal direction of the main body, by connecting the screw hole 131 and the bracket (not shown) with a bolt installed in the vertical direction and fixed in various directions Of course it is possible.

In addition, the unevenness 132 is repeatedly formed to the outside of the cooling fin 130, the reason why the unevenness 132 is formed is to increase the heat dissipation effect as the area in contact with the air by the unevenness 132 increases the vortex It improves the performance of the tube A and minimizes the area in direct contact with the body to reduce the possibility of burns if the vortex tube A is overheated.

Meanwhile, a slip nut fixing part 121 is further formed in the cooling groove 120, and the slip nut fixing part 121 has a nut on the slip nut fixing part 121 when fixing the vortex tube A to a wall or the like. It is easy to adjust the position freely by inserting (not shown) and fixing by bolt. That is, the nut (not shown) inside the slip nut fixing part 121 is slidable.

In addition, the cooling groove 120 is formed with a hot discharge portion 122 of the shape cut in the cap fixing part 102 direction. This, the hot discharge portion 122 is a portion for the high temperature heat discharged through the control valve 300 can be discharged to the outside because the groove on the outer surface of the main body 100, the inner diameter of the main body 100 If you squeeze the groove to a larger size, it is processed into a naturally ventilated form.

Since the heat dissipation function is improved by the cooling fin 130 and the cooling groove 120 in which the unevenness 132 is formed, the heat of the vortex tube A is discharged faster than the conventional structure, so that the performance of the vortex tube A is improved. The effect is increased (the performance is improved as the heat of the vortex tube is quickly discharged and the heat (energy) can be taken out of the reversed airflow). In addition, the main body 100 as a whole (parts in contact with the air flow inside and outside unevenness) is integrally formed so that the heat conduction can be quickly utilized to maximize the heat dissipation effect by the unevenness 132.

Meanwhile, when the vortex tube A is applied to the cabinet cooler, the cooling fins 130 and the cooling grooves 120 are discharged through the air discharge grooves 106 of the cooling fins 130 and the cooling grooves 120. Rising on the outer surface and has the effect of cooling the vortex tube (A), thereby increasing the efficiency of the vortex tube (A). This, the cooling effect by the exhaust air will be described in detail later.

The vortex generator 200 is inserted into the generator seating part 104 of the main body 100 and is configured to spray compressed air by receiving compressed air from the compressed air inlet 103.

In detail, the vortex generator 200 has a circular first inlet 210 receiving compressed air from the compressed air inlet 103, and inputs compressed air through the first inlet 210. The second inlet 220 is provided with an inlet 221 for the formation, a circular vortex rotation chamber 230 is formed by the compressed air through the inlet 221 to cause vortex, the vortex rotation chamber 230 is formed with a through hole 240 for discharging cold air to one side.

Here, the second entry part 220 is formed by chamfering both sides of a circular shape having a larger diameter than the first entry part 210 in a plane. That is, the second entry portions 220 and 220 'on both sides are formed parallel to each other.

On the other hand, referring to the enlarged view shown in Figure 5 'a' to describe the inlet (221,221 '), the inlet (221,221') and the first inlet 221 formed in the second inlet 220 on one side and And a second inlet 220 'formed at the second inlet 220' on the other side, and the first inlet 221 and the second inlet 221 'are formed on a horizontal line in the center of the vortex rotation chamber 230. It penetrates in the vertical direction with respect to. Here, the first inlet 221 is located on the right side of the second inlet 220 and the vortex rotation chamber 230 of the upper, the second inlet 221 ′ is the second inlet 220 and the lower It is located on the left side of the vortex rotating chamber 230.

The positions of the inlets 221 and 221 ′ are for injecting compressed air in a tangential direction inside the vortex rotation chamber 230 so that a strong vortex may be formed and details will be described later.

In addition, an insertion groove 201 is formed on an outer circumferential surface of the vortex generator 200, a rubber ring 202 is inserted into the insertion groove 201, and the rubber ring 202 is connected to the generator seating part 104. When the vortex generator 200 is inserted, it is a configuration for preventing the leakage of compressed air.

On the other hand, the noise is generated due to the cold discharged through the through hole 240 of the vortex generator 200 and the heat discharged to the hot discharge portion 122 formed in the cap fixing part 102 direction, which is a vortex generator 200 ) And the silencers 250a and 250b are added to the space between the cold air discharge unit 110 and the hot discharge unit 122 and the inner side control valve 300. In addition, the silencers 250a and 250b are porous in the form of sintered metal particles, and are superior in durability to filter-type silencers using conventional styrofoam. That is, in the case of the conventional silencer, the cold air injection unit is lowered to minus 40 degrees to minus 50 and the high temperature outlet is raised to 40 degrees to 90 degrees and contractions and expansions occur due to temperature changes. It was difficult to properly perform the role, in order to solve this problem in the present invention by sintering the metal particles made of a porous interior to minimize deformation and ensure durability.

In particular, unlike the case of the high temperature discharge unit 122, in the case of the silencer 250a coupled to the cold air discharge unit 110 side, the silencer 250a may be pushed out due to the cold air injected at a high speed and may fail to perform its function. Therefore, a male screw (not shown) is formed on one side of the silencer 250a, and a corresponding female screw (not shown) is formed on the vortex generator 200 to which the silencer 250a is coupled so as to be screwed to the silencer 250a. Prevented from leaving.

Since the silencers 250a and 250b that reduce noise are already used in the related art, detailed descriptions on the internal structure and operation thereof will be omitted.

The control valve 300 is positioned to open and close one side of the air circulation portion 105, and is configured to adjust the flow rate and cooling capacity of the compressed air, the control valve 300 is installed by the cap 140 The cap 140 is screwed into the cap fixing part 102 of the main body 100 and the female thread 141 is formed therein, and the male screw 301 corresponding to the female thread 141 of the cap 140 is adjusted. Cap 140 and the control valve 300 is formed on one end of the valve is fastened to each other, the control valve 300 and the cap 130 is fastened to each other is screwed to the cap fixing part 102 of the main body 100 It is fixed.

That is, the cap 140 is fixed, one end of the control valve 300 connected to the female screw 141 of the cap 140 is exposed to the outside of the cap 140, the control valve 300 is exposed to the outside in this way Rotating one end of the) moves in the longitudinal direction of the main body 100 by the male screw 301 and the female screw 141. Accordingly, it is to adjust the degree of opening and closing the control valve 300 of the air circulation unit 105, and to control the flow rate and cooling capacity of the cold air.

On the other hand, the control valve 300 may be formed of a stainless steel having a low thermal conductivity, it is not limited to this, it turns out that it can also be formed of other materials having a low thermal conductivity.

Therefore, the vortex generator 200 is installed in the generator seating part 104 of the main body 100, the silencer 250 is added to the front of the vortex generator 200, and the fastening part of the main body 100 ( The male screw 111 of the cold air discharge unit 110 is screwed into the female screw 107 formed in the 101 to accommodate and fix the silencer 250 and the vortex generator 200 into the main body 100. In addition, the coupling hole 103a is screwed into the compressed air inlet 103 of the main body 100, the control valve 300 and the cap 140 screwed to each other is screwed to the cap fixing portion 102 The vortex tube A of the 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, the general configuration of the present invention has been described, but in the following description, the operation of the present invention will be described in detail with reference to the accompanying drawings.

7 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. 7, through the compressed air inlet 103 of the vortex tube A, compressed air having a pressure of 5.5 to 6.9 atm through the inlets 221 and 221 ′ formed above and below the vortex generator 200. 230) A rotary airflow is formed inside the rotary airflow, and the rotary airflow rotates with a rotation speed of up to 1 million RPM, and a phenomenon in which airflow moves to the outside of the vortex rotation chamber 230 occurs due to the pressure of the injected compressed air. In this case, the vortex rotation chamber 230 of the rear is wider than the front through hole 240 of the vortex generator 200 due to the rotational force of the air flow (force applied to the outside by the centrifugal force) to the rear rather than the front. The airflow moves.

The forward air flow moved as described above moves through the extended air circulation part 105 and collides with the control valve 300 blocking the air circulation part 105. The reverse air flow reversed by the collision is caused by the air circulation part ( 105 is moved 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, even if the air circulation portion 105 is blocked by the control valve 300, the transfer of energy as described above occurs so that a temperature difference occurs between the forward air of the outer side and the reverse air of the inner side. Since it is not discharged, it is discharged to the outside through the through hole 240 in front of the vortex generator 200 together with the reverse airflow, the effect of lowering the actual temperature is lost.

At this time, since opening the control valve 300 which is blocking the air circulation portion 105, the effect of the high-temperature forward air flow is discharged to the outside, the amount of the high-temperature air flow back as much as the amount of the forward air flow discharged is reduced to cold steel The air can be discharged.

However, since the amount of cold air generated is reduced as compared to the amount of air introduced as the air discharged to the outside increases, the control valve 300 is used to properly adjust the amount.

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.

Next, the cabinet cooler to which the vortex tube A configured as described above is applied will be described with reference to the accompanying drawings.

8 is a cross-sectional view showing a state in which the vortex tube is applied to the cabinet cooler according to an embodiment of the present invention.

First of all, the cabinet cooler is an inexpensive and reliable method for cooling the electronic control device and preventing impurities from penetrating into the inside. It is mainly a PLC panel, various wired / wireless communication equipment, a motor control center, and a relay. It is used for cooling switchboards and computer cabinets.

Looking in detail with reference to Figure 8, as described above, the fastening portion 101 of the vortex tube 100 for discharging cold air is inserted into the through hole 401 of the cabinet wall 400, the fastening portion 101 The vortex tube A and the cabinet wall 400 are coupled to each other by using the fixing nut 402, and the cabinet wall is formed by the air outlet groove 106 between the fastening portion 101 and the fixing nut 402. 400, the air inside is discharged. In other words, when used as a cabinet wall 400 for cooling the control box of the electronic device, a structure for discharging the internal air is additionally required due to the structure of continuously blowing air into an isolated space. It is discharged through the air discharge groove 106 of (A).

As such, since the vortex tube A itself has a discharge function, a structure in charge of a separate outlet function can be omitted from the cabinet wall 400, thereby reducing the assembly process and manufacturing cost.

On the other hand, the discharged air rises on the outer surfaces of the cooling fins 130 and the cooling grooves 120 of the vortex tube 100 and has an effect of cooling the vortex tube A, thus improving the efficiency of the vortex tube A. Will be raised higher.

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.

As described above, the vortex tube according to the present invention forms a main structure in which the cooling fins and the cooling grooves are formed and the air circulation unit inside, thereby generating a natural and rapid cooling effect (air cooling). It provides the effect of improving the cooling efficiency by preventing overheating.

In addition, it provides an easy operation of the control valve for adjusting the flow rate and cooling capacity of the cold air.

In addition, when applied to the cabinet cooler for cooling the control box of the electronic device, the air discharge groove is formed separately in the fastening part formed with the screw part, so that the air inside the cabinet can be discharged to the outside, so it is in charge of a separate outlet function. It provides the effect that the structure can be omitted.
