Abstract
Description
Technical Field
[0001] This utility model relates to the field of machine tool processing technology, and in particular to a heat dissipation vortex tube for an ultra-low temperature micro-volume environmentally friendly cooling system. Background Technology
[0002] Low-temperature micro-cooling is a typical quasi-dry cutting method. Compressed gas is cooled to 0 to -30°C through one or more stages, mixed with a trace amount of lubricating medium, and vaporized to form micron- and nano-sized atomized particles. These particles are then sprayed onto the machining area for lubrication and cooling. It is mainly used for lubrication and cooling in gear hobbing, lathe turning of outer diameters, inner holes, and end faces, as well as in metal cutting, CNC machining center milling, grooving, hole drilling, boring, and general machining equipment cutting processes.
[0003] When compressed air is cooled using a vortex tube assembly, while ultra-low temperature cold air is generated at the lower outlet of the diverter valve, a large amount of high temperature gas is generated on the inner wall of the vortex tube and discharged from the tail silencer. If the high temperature conducted by these high-temperature and high-pressure gases cannot be dissipated in time, it will directly affect the rate of temperature drop and temperature difference at the cold air inlet, making it difficult to obtain ultra-low temperature cooled compressed air more quickly and at lower temperatures. Utility Model Content
[0004] The purpose of this invention is to provide a heat dissipation vortex tube for an ultra-low temperature micro-volume environmentally friendly cooling system. It aims to solve the technical problem that when the vortex tube assembly is used for compressed air cooling in the prior art, the high temperature conducted by the high-temperature and high-pressure gas cannot be dissipated in time, which will directly affect the rate of temperature drop and temperature difference of the cold air inlet, making it difficult to obtain ultra-low temperature cooled compressed gas faster and at lower temperatures.
[0005] To achieve the above objectives, this utility model employs a heat dissipation vortex tube for an ultra-low temperature micro-volume environmentally friendly cooling system, comprising a heat dissipation valve body, a distribution mesh, a vortex tube, a vortex seat, a distribution valve, a seat nut, an air inlet connector, a regulating valve, and a muffler. The distribution mesh is disposed within the heat dissipation valve body. One end of the vortex tube is threadedly connected to the heat dissipation valve body and located below the distribution mesh. The vortex seat is fixedly connected to the vortex tube and located outside the vortex tube, with the vortex tube penetrating through the vortex seat. The distribution valve is fixedly connected to the vortex tube and located below the vortex tube. The seat nut is threadedly connected to the vortex seat and located below the distribution valve. The air inlet connector is threadedly connected to the vortex seat and located outside the vortex seat. The regulating valve is threadedly connected to the heat dissipation valve body and located above the distribution mesh. The muffler is threadedly connected to the heat dissipation valve body and located above the heat dissipation valve body.
[0006] The heat dissipation valve body includes multiple heat dissipation fins, which are integrally formed with or fixedly connected to the heat dissipation valve body and located on the outside of the heat dissipation valve body. The multiple heat dissipation fins are evenly distributed along the axial circumference of the heat dissipation valve body.
[0007] The heat sink has heat sink holes, and there are two or more heat sink holes, which are symmetrically and evenly distributed on the heat sink.
[0008] The ultra-low temperature micro-volume environmentally friendly cooling system's heat dissipation vortex tube also includes a micro-volume nozzle and a cold air pipe. The micro-volume nozzle is threadedly connected to the vortex seat and is located above the vortex seat. The cold air pipe is fixedly connected to the micro-volume nozzle and is located above the micro-volume nozzle, and the cold air pipe passes through the heat sink hole.
[0009] This utility model discloses a heat dissipation vortex tube for an ultra-low temperature micro-volume environmentally friendly cooling system. In practical use, room temperature compressed air enters the diversion valve from the air inlet joint, then enters the vortex tube through the diversion valve. After entering the vortex tube and the diversion mesh, the compressed air enters the regulating valve. After passing through the regulating valve, the high-temperature compressed air is discharged after noise elimination by the silencer. The ultra-low temperature cold air formed in the central region of the vortex tube passes through the diversion valve, reaches the end of the regulating valve, and then turns back. The returned cold air passes through the center of the vortex tube and is discharged from the seat nut. This solves the problem that the high temperature conducted by high-temperature and high-pressure gas cannot be dissipated in time, which directly affects the rate of temperature drop and temperature difference at the cold air inlet.

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.
[0018] Please see Figures 1 to 5 This utility model provides a heat dissipation vortex tube for an ultra-low temperature micro-volume environmentally friendly cooling system, including a heat dissipation valve body 1, a flow divider 9, a vortex tube 2, a vortex seat 3, a flow divider valve 4, a seat nut 5, an air inlet connector 6, a regulating valve 10, and a silencer 11; the flow divider 9 is disposed inside the heat dissipation valve body 1, one end of the vortex tube 2 is threadedly connected to the heat dissipation valve body 1 and is located below the flow divider 9, the vortex seat 3 is fixedly connected to the vortex tube 2 and is located outside the vortex tube 2, and the vortex tube... 2. The vortex seat 3 is penetrated by the vortex valve 4, which is fixedly connected to the vortex tube 2 and located below the vortex tube 2. The seat end nut 5 is threadedly connected to the vortex seat 3 and located below the vortex valve 4. The air inlet connector 6 is threadedly connected to the vortex seat 3 and located outside the vortex seat 3. The regulating valve 10 is threadedly connected to the heat dissipation valve body 1 and located above the vortex mesh 9. The muffler 11 is threadedly connected to the heat dissipation valve body 1 and located above the heat dissipation valve body 1.
[0019] In this embodiment, A is the ambient temperature compressed air inlet, B is the cryogenic compressed cold air outlet, and C is the high temperature compressed air outlet. The inlet end face of the vortex tube 2 is connected to the upper end face of the diverter valve 4, and the lower end face of the diverter valve 4 is connected to the upper end face of the seat nut 5. The diverter valve 4 is pressed against the inlet end face of the vortex tube 2 by the seat nut 5. The seat nut 5 is threadedly connected to the vortex seat 3 and presses against the diverter valve 4 and the vortex tube 2. The seat nut 5 has a through hole, through which the cold air outlet of the diverter valve 4 passes. The inlet connector 6 is threadedly fixedly connected to the diverter seat and is located on the outer circumferential surface of the diverter seat. Pipe 2 is threadedly fixed inside the heat dissipation valve body 1, and the diverter 9 is rotated and pressed into the heat dissipation valve body 1 through the vortex tube 2. The diverter 9 is connected to the end face of an inner hole provided inside the heat dissipation valve body 1. The gap between the lower end face of the regulating valve 10 and the upper end face of the heat dissipation valve body 1 is adjusted by rotating the thread. The lower end face of the silencer 11 is threadedly fixed to the tail of the heat dissipation valve body 1. The silencer 11 has a hollow structure, which allows for smooth exhaust and eliminates noise. Low-temperature cold air is discharged from the lower end of the seat nut 5 for processing cooling. This solves the problem that the high temperature of the high-temperature and high-pressure gas conduction cannot be dissipated in time, which will directly affect the rate of temperature drop and temperature difference of the cold air outlet.
[0020] Furthermore, the heat dissipation valve body 1 includes a plurality of heat dissipation fins 102, which are integrally formed with or fixedly connected to the heat dissipation valve body 1 and located on the outer side of the heat dissipation valve body 1, and the plurality of heat dissipation fins 102 are evenly distributed along the axial circumference of the heat dissipation valve body 1.
[0021] In this embodiment, each heat sink 102 is a cylindrical thin sheet, and there are uniform groove gaps between the heat sinks 102, so that all the heat sinks 102 are distributed in a tooth shape, thereby greatly increasing the heat dissipation area and allowing the high temperature conducted by the vortex tube 2 to the heat dissipation valve body 1 to be cooled quickly.
[0022] Furthermore, the heat sink 102 has heat sink holes 101, and there are two or more heat sink holes 101, which are symmetrically and evenly distributed on the heat sink 102.
[0023] In this embodiment, the heat sink hole 101 can completely penetrate all the heat sinks 102, or it can penetrate to the position where one or more heat sinks remain. The setting of the heat sink hole 101 not only further increases the heat dissipation area, but also increases the cooling gas channel, so that the high temperature conducted by the vortex tube 2 to the heat dissipation valve body 1 can be cooled more quickly.
[0024] Furthermore, the heat dissipation vortex tube of the ultra-low temperature micro-volume environmentally friendly cooling system also includes a micro-volume nozzle 7 and a cold air pipe 8. The micro-volume nozzle 7 is threadedly connected to the vortex seat 3 and is located on the upper end face of the vortex seat 3. The cold air pipe 8 is fixedly connected to the micro-volume nozzle 7 and is located above the micro-volume nozzle 7. The cold air pipe 8 passes through the heat dissipation fin hole 101.
[0025] In this embodiment, the micro-air nozzle 7 is threadedly connected to the upper end face of the vortex seat 3. Two or more micro-air nozzles 7 can be provided and evenly distributed on the upper end face of the vortex seat 3. The micro-air nozzle 7 has a larger inner hole and a smaller hole inside, and the two holes are completely connected. The lower end of the micro-air nozzle 7 is threadedly fixedly connected to the upper end face of the vortex seat 3. The smaller hole of the micro-air nozzle 7 is connected to the air chamber inside the vortex seat 3. The number of cooling air pipes 8 corresponds to the number of micro-air nozzles 7. The lower end of the cooling air pipe 8 is fixedly connected to the micro-air nozzle 7. The upper end of the cooling air pipe 8 is connected to the heat sink hole 101 of the heat sink 102 at the lower end of the heat sink valve body 1 and is fixedly connected to it. Through the above connection, the cooling gas transmitted from the vortex seat 3 enters the heat sink hole 101 of the heat sink valve body 1, so that the high temperature conducted by the vortex pipe 2 to the heat sink valve body 1 is further cooled more quickly.
[0026] The beneficial effects of this utility model are as follows: After the compressed air passes through the vortex tube assembly, while ultra-low temperature cold air is generated at the lower outlet of the diverter valve 4, a large amount of high temperature gas is generated on the inner wall of the vortex tube 2 and discharged from the silencer 11 at the tail. This allows the vortex tube assembly to generate even lower temperature ultra-low temperature cold air more quickly even at higher ambient temperatures, in order to meet the need for rapid cooling of the high heat generated in machine tool cutting. This better ensures the machining accuracy of the machine tool, significantly improves tool life, greatly reduces cooling smoke, and significantly improves the workshop production environment. This structure mainly includes the heat dissipation valve body 1, the micro air nozzle 7, and the cold air pipe 8. Its structure is simple and easy to mass-produce.
[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
