Description

Technology Field

[0001] The present invention relates to a high-performance vortex tube capable of enhancing the temperature separation effect of a gas, and more specifically, to a high-performance vortex tube capable of enhancing the temperature separation effect of a gas by forming a vortex tube that generates heat in an outwardly contracted shape to increase the rotational motion intensity of the heat, thereby increasing the efficiency of heat generation, and also by providing a partition member at the inlet side of a cold air nozzle that discharges cold air to control the temperature of the cold air by controlling the amount of cold air passing through, thereby increasing the efficiency of cold air generation. Background Technology

[0002] Generally, a vortex tube (VT) is well known as a device that utilizes the characteristics of fluid vortex motion to appropriately separate a fluid into high-temperature and low-temperature regions. Such vortex tubes are widely used not only in various refrigeration and air conditioning systems but also, more recently, in applications that effectively separate fluids into high-energy and low-energy components.

[0003] The vortex tube, referred to as the vortex tube above, is a typical form of vortex tube applied to gas flow. It is a very simple form consisting mainly of a vortex chamber, a vortex tube, a hot exit, and a cold exit. Since there are no active parts inside the device, it does not require driving energy and is a semi-permanent device that requires no maintenance.

[0004] In most cases, a nozzle is installed at the outer edge of the vortex chamber to supply fluid in the circumferential direction, so when high-pressure fluid flows in, strong vortex motion is initiated inside the vortex chamber. Subsequently, the gas proceeds toward the vortex tube in the right direction while undergoing vortex motion. Inside the vortex tube, the fluid flows toward the right outlet of the tube accompanied by strong rotational motion; at this time, due to the centrifugal force of the flow, the pressure and temperature increase as they move away from the central axis of the tube and decrease towards the central axis, resulting in a very complex flow in which a strong temperature gradient is formed across the cross-section of the tube. This flow proceeds toward the right outlet of the tube, and the portion with high temperature and pressure is discharged through the outer edge of the plug installed at the outlet. For this reason, the right end of the vortex tube in Fig. 1 is referred to as the high-temperature outlet.

[0005] Meanwhile, the relatively low-temperature fluid in the center of the vortex flow flowing to the right of the vortex tube is unable to flow further to the right due to the plug and becomes stagnant, flowing back to the left side of the tube. Therefore, although the vortex tube has a very simple shape, a very complex flow field is formed in which a flow directed to the left is formed in the center of the tube and a strong rotational flow directed to the right is formed near the outer wall. During this flow process, strong shear forces are generated even in the direction perpendicular to the flow, resulting in very large energy loss inside the vortex tube. For this reason, the temperature separation efficiency of current vortex tubes is very low, and research for improvement is necessary.

[0006] And, the flow in the center of the pipe directed toward the left side of the pipe is discharged through the nozzle at the left end. Therefore, since a flow with low temperature and pressure is discharged at the nozzle outlet, the temperature of the fluid supplied to the vortex tube inlet can be separated and discharged into a high-temperature section on the right and a low-temperature section on the left.

[0007] While the above vortex tube has the advantage of a simple structure that does not require driving energy, due to the very complex flow generated inside the vortex tube, research on the optimal shape of the vortex tube has not been sufficiently conducted until recently. Furthermore, when the operating flow rate and pressure of the vortex tube change, only the method of simply changing the number of nozzles at the inlet of the vortex tube to 3, 5, or 7, as shown in Fig. 2, is adopted, and the number of nozzles can be appropriately selected according to the pressure and flow rate of the gas supplied to the vortex tube. In addition, since the intensity of the vortex generated inside the vortex chamber can be increased depending on the pressure of the supplied fluid or the number of nozzles, the number of nozzles used is mainly determined by a trial-and-error method.

[0008] Therefore, when attempting to obtain the required flow rate and temperature in the high-temperature and low-temperature sections of a vortex tube, existing vortex tubes require countless trials and errors, and there are limitations in properly controlling the temperature separation performance.

Specific details for implementing the invention

[0020] The specific details for implementing the present invention will be explained in more detail below with reference to the attached drawings.

[0021] The present invention relates to a high-performance vortex tube capable of enhancing the temperature separation effect of a gas, which increases the efficiency of generating heat by increasing the rotational motion intensity of the heat by forming the heat-generating vortex tube in an outwardly contracted shape, and also increases the efficiency of generating cold air by providing a partition member at the inlet side of the cold air nozzle that discharges cold air to control the cold air temperature by controlling the amount of cold air passing through. Referring to FIGS. 3 to 9, the vortex tube comprises a vortex chamber (10), a vortex tube (20) formed in an outwardly contracted tube shape, a plug (40), and a cold air nozzle (30).

[0022] To implement the present invention, a vortex chamber (10) is first provided to form a vortex by rotating compressed air introduced through an inlet as shown in FIG. 3. As shown in FIG. 2, which is a conventional drawing, the vortex chamber (10) is provided with a vortex nozzle that supplies fluid in a circumferential direction within the vortex chamber (10), and the heat generated by generating a vortex from the supplied compressed air is moved through the path of the vortex tube (20) described later.

[0023] A vortex tube (20) is extended and provided on one side of the above vortex chamber (10). The vortex tube (20) is formed in a tubular shape to move heat generated by a vortex formed within the vortex chamber (10). In the present invention, to improve the temperature separation performance of heat moving in a vortex along the inner surface of the tubular body within the vortex chamber (10), the vortex tube (20) is formed in an outwardly constricting tube shape as shown in FIG. 3, in which the inner diameter decreases as it moves in the direction of heat movement, thereby increasing the rotational movement intensity of the heat and generating a large temperature gradient, so as to increase the heat generation efficiency.

[0024] At this time, although not shown, if the inner surface of the tube body of the above vortex tube (20) is formed in a multi-stage curved shape, the vortex waves can be generated more significantly to increase the heat temperature.

[0025] Meanwhile, as shown in FIG. 3, a plug (40) is provided at the outer end of the vortex tube (20) to expel heat moving within the vortex chamber (10) to the outside.

[0026] The plug (40) is configured to form an ejection path for the ejection of heat. In the present invention, as shown in FIG. 4, a screw portion (41) is formed on the rear side of the plug (40) and configured to move back and forth by adjusting the screw portion (41). Due to this structure, the flow rate of the ejected heat can be controlled by adjusting the ejection path distance between the outer end of the vortex tube (20) and the plug (40).

[0027] At this time, the plug (40) can be implemented in various forms, such as in FIG. 4 (a), it can be formed in a semicircular shape in a direction corresponding to the direction of movement of heat, in FIG. 4 (b), it can be formed in a triangular shape having a vertex (43) and inclined surfaces (44) on both sides, and in FIG. 4 (c), it can be formed in a trapezoidal shape having a vertical friction surface (45) perpendicular to the direction of movement of heat and inclined surfaces (44) on both sides.

[0028] Meanwhile, as shown in FIG. 3, a cold air nozzle (30) is provided that extends in a straight line along the vortex tube (20) on the other side of the vortex chamber (10) and discharges cold air to the outside, which is converted as heat from the vortex formed in the vortex chamber (10) is returned by the plug (40).

[0029] The above cold air nozzle (30) is basically formed in an outwardly expanding shape to expel cold air, and in addition to this, as shown in (a) of FIGS. 5 and 6, a partition member (50) is provided so that resistance is generated to the cold air moving at the inlet side of the cold air nozzle (30) that expels cold air.

[0030] The amount of cold air moved toward the cold air nozzle (30) can be adjusted according to the diameter of the partition member (50), and as a modified embodiment, as shown in FIG. 7 (a), the partition member (50) can be formed in the shape of a vertical plate that resists perpendicularly to the direction of movement of the cold air, and as shown in FIG. 7 (b), it can be formed in an outwardly reduced shape in which the inner diameter is reduced to guide movement while reducing the area of ​​movement of the cold air.

[0031] In addition, as shown in Fig. 7 (c), the inwardly inclined portion (53) and the outwardly inclined portion (54) can be formed in a shape in which they are integrally bent inwardly toward the direction of movement of cold air.

[0032] And, as shown in Fig. 6 (b), the inner surface of the cold air nozzle (30) can be configured to be formed in an outwardly curved shape to flexibly expand the amount of cold air flow.

[0033] Meanwhile, as a modified embodiment of the present invention, a horizontal tube (32) is extended at the outer end of the cold air nozzle (30) formed in an outwardly expanding shape as shown in FIGS. 8 and 9, a fixed shaft (36) is provided at the center side within the horizontal tube (32), and a plurality of blades (35) are provided radially on the outer circumference of the fixed shaft (36) and parallel to the direction of movement of the cold air, so as to be configured to lower the temperature of the cold air by expanding the cold air.

[0034] In this structure, as shown in FIG. 9, the pressure of the cold air increases in the narrow space between the blades (35) and the temperature decreases, so cold air of a lower temperature can be obtained, thereby increasing the efficiency of cold air generation.

[0035] According to the high-performance vortex tube of the present invention, which can enhance the temperature separation effect of the gas as described above, the heat generation efficiency is increased by forming the heat-generating vortex tube in an outwardly contracted shape to increase the rotational motion intensity of the heat, and additionally, the cold air generation efficiency is increased by providing a partition member at the inlet side of the cold air nozzle that discharges cold air to control the cold air temperature by controlling the amount of cold air passing through.

[0036] The present invention described above has been explained with reference to an exemplary embodiment illustrated in the drawings, but this is merely illustrative, and it should be made clear to those skilled in the art that various modifications and equivalent alternative embodiments are possible therefrom. Accordingly, the true technical scope of protection of the present invention should be interpreted by the appended claims, and all technical ideas within an equivalent scope should be interpreted as being included within the scope of rights of the present invention.
