Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat dissipation structure of high-frequency transformer, and particularly relates to a heat dissipation structure of high-frequency transformer. BACKGROUND

[0002] The high-frequency transformer will generate significant temperature rise in the high-power working state, and the traditional heat dissipation structure has the common problem of poor maintainability. Since the internal space of the transformer is compact and the heating elements are dense, the existing heat sink is mostly welded or bolted as a whole, so that when problems such as condenser pipe blockage, fan failure or dust accumulation on the dust screen occur, the entire heat dissipation system needs to be disassembled for maintenance. Especially in the heat dissipation architecture of multiple modules working together, the device needs to be interrupted for several hours for disassembly when a single component is damaged, which seriously reduces the efficiency of the device.

[0003] Therefore, the present application provides a heat dissipation structure of high-frequency transformer to solve the above problems. SUMMARY

[0004] The purpose of the present application is to provide a heat dissipation structure of high-frequency transformer, which can significantly improve the heat dissipation efficiency by generating low-temperature airflow through the refrigeration module, forcibly conveying it to the heat-conducting metal plate to realize directional heat exchange, and forming a front-to-back airflow channel with the air vents. The double-channel design of the drainage groove and the duct accelerates the circulation of cold air, and the heat-conducting metal plate closely fits the side wall of the transformer to achieve efficient heat conduction, thereby solving the problems raised in the background art.

[0005] To achieve the above purpose, the present application provides the following technical scheme:

[0006] A heat dissipation structure of high-frequency transformer, comprising a transformer main body, a heat dissipation frame is arranged on the side wall of the transformer main body, and air vents are arranged at the front and rear ends of the transformer main body, a refrigeration module, a fan module and a dust prevention module are installed in the inner wall of the heat dissipation frame, a condenser pipe is arranged inside the refrigeration module, a duct is arranged at the upper end of the condenser pipe, a heat-conducting metal plate is arranged at the front end of the condenser pipe, the heat-conducting metal plate is closely installed on the outer wall of the transformer main body, and a quick-release structure is arranged at the bottom end of the refrigeration module.

[0007] The quick-release structure comprises a connecting circular groove arranged at the bottom end of the refrigeration module, a rotating shaft is installed in the inner wall of the connecting circular groove, an adjusting block is installed at one end of the rotating shaft, a limiting spring is installed on the side wall of the adjusting block, a limiting rod is arranged in the inner part of the adjusting block, a sliding groove is arranged on the inner wall of the heat dissipation frame, the adjusting block slides in the sliding groove, and a drainage groove is arranged on the outer wall of the heat dissipation frame.

[0008] In further embodiments, the two symmetrical drainage grooves are provided with drainage openings on the outer walls.

[0009] In further embodiments, the U-shaped condensing pipe is connected at the upper end to the air inlet of the drainage groove via a duct, and the lower end of the condensing pipe is provided with an air outlet inside the refrigeration module.

[0010] In further embodiments, the bottom end of the fan module and the dustproof module are provided with a connecting circular groove, and the same quick-release structure as the refrigeration module is installed via the connecting circular groove. The refrigeration module, the fan module and the dustproof module are movably embedded in the inner wall of the heat dissipation frame, and a fixing bolt is provided in the upper end inner wall of the refrigeration module, the fan module and the dustproof module, and the fixing bolt is screw-mounted on the side wall of the transformer body.

[0011] In further embodiments, the inner wall of the fan module is provided with a plurality of vertical strip-shaped combined fans, which are arranged on one side of the condensing pipe.

[0012] In further embodiments, the inner wall of the dustproof module is provided with a plurality of vertical strip-shaped dustproof screens.

[0013] In further embodiments, the dustproof screen and the combined fan are arranged in parallel correspondence, and the dustproof screen and the combined fan are movably inserted into the inner wall of the fan module and the dustproof module, respectively.

[0014] In further embodiments, the top end of the refrigeration module is provided with a temperature monitor, and the temperature sensor at the bottom end of the temperature monitor is arranged in the side wall of the transformer body and the refrigeration module, respectively.

[0015] Compared with the prior art, the present application has the following advantages:

[0016] Firstly, when the heat dissipation structure of the high-frequency transformer is used, the heat dissipation structure generates low-temperature air flow through the refrigeration module, which is forced to be transported to the heat-conducting metal plate to realize directional heat exchange, and the air flow channel is formed through the front and rear air vents, which significantly improves the heat dissipation efficiency. The double-channel design of the drainage groove and the duct accelerates the circulation of cold air, and the heat-conducting metal plate closely contacts the side wall of the transformer to realize efficient heat conduction.

[0017] Secondly, the modular quick-release design allows the refrigeration, fan and dustproof modules to be independently maintained. When the adjusting block is pulled to release the constraint of the limiting rod, the refrigeration module can be flipped along the rotating shaft to directly expose the fan module and the dustproof screen, and the dustproof screen can be plugged and replaced. The condensing pipe can be quickly repaired through the open space after flipping, which shortens the average repair time by more than 70%. BRIEF DESCRIPTION OF DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] Please refer to Figures 1-6 A heat dissipation structure of high-frequency transformer, comprising a transformer main body 1, the heat dissipation structure is provided with a heat dissipation frame 3 on the side wall of the transformer main body 1, and ventilation openings 2 are formed on the front and rear ends of the main body to form air flow channels. A dustproof module 8, a fan module 7 and a refrigeration module 4 are sequentially movably arranged in the heat dissipation frame 3 according to the air flow direction, and the bottoms of the three modules are respectively provided with quick release units of the same structure. Taking the refrigeration module 4 as an example, a rotating shaft 15 is arranged in a connecting circular groove 16 at the bottom end of the refrigeration module 4, the outer end of the rotating shaft 15 is connected with an adjusting block 12 provided with a limiting spring 13, and a limiting rod 14 is inserted into the adjusting block 12 to lock the position. A sliding groove 11 is formed in the side wall of the heat dissipation frame 3 and is in sliding cooperation with the adjusting block 12.

[0029] During daily heat dissipation, air enters the duct 10 through the drainage groove 9 and the drainage opening 21, and is refrigerated by the condenser pipe 5 arranged in a serpentine shape in the refrigeration module 4. The combined fans 18 of the fan module 7 blow the cold air flow to the heat-conducting metal plate 6 at the front end of the refrigeration module 4, and the metal plate is tightly attached to the side wall of the transformer main body 1 to exchange heat. The heated air flow is discharged from the rear ventilation opening 2, and the temperature data is monitored in real time by the temperature monitor 20.

[0030] The module maintenance operation process is as follows: after the fixing bolt 19 is loosened, the refrigeration module 4 is pulled outward to drive the adjusting block 12 to move along the sliding groove 11. When the limiting rod 14 is disengaged from the locking position, the limiting spring 13 rebounds to release the adjusting block 12, at this time, the adjusting block 12 is held and rotated, and the refrigeration module 4 is flipped outward with the rotating shaft 15 as the fulcrum. At this time, the internal space of the heat dissipation frame 3 is completely exposed, and the dustproof module 8 slot parallel to the combined fan 18 of the fan module 7 can be seen. The dustproof module 8 is extracted upward, and the vertical strip-shaped dust screen 17 in the dustproof module 8 can be taken out for cleaning or replacement. The combined fan 18 of the fan module 7 is also designed in a plug-in manner, and the fan blade unit can be directly replaced after disassembly. When the refrigeration module 4 needs to be repaired, it only needs to be kept in the flipped state, and the condenser pipe 5 is completely exposed, and through the conduit 10, quick dredging or pipeline maintenance can be realized. After maintenance, reverse operation can restore the working position of each module, and the limiting rod 14 automatically locks the adjusting block 12.

[0031] The working principle of the present application is as follows: as shown in the figure, it comprises a transformer body 1, the heat dissipation structure is installed on the side wall of the transformer body 1, and the heat dissipation frame 3 is installed on the side wall of the transformer body 1. Ventilation openings 2 are formed at the front and rear ends of the main body to form air flow channels. The heat dissipation frame 3 is internally sequentially movable and embedded with dustproof modules 8, fan modules 7 and refrigeration modules 4 according to the air flow direction, and the bottoms of the three are respectively provided with quick release units of the same structure. Taking the refrigeration module 4 as an example: a rotating shaft 15 is arranged in the connecting circular groove 16 at the bottom end of the refrigeration module 4, the outer end of the rotating shaft 15 is connected with an adjusting block 12 provided with a limiting spring 13, and a limiting rod 14 is inserted into the adjusting block 12 to lock the position. The sliding groove 11 is opened on the side wall of the heat dissipation frame 3 and is in sliding cooperation with the adjusting block 12.

[0032] During daily heat dissipation, air enters the conduit 10 from the drainage groove 9 through the drainage opening 21 and is transported to the condenser pipe 5 arranged in a serpentine shape in the refrigeration module 4 to refrigerate. The multiple combined fans 18 of the fan module 7 blow the cold air flow to the heat-conducting metal plate 6 at the front end of the refrigeration module 4, and the metal plate tightly abuts the side wall of the transformer body 1 to implement heat exchange. The temperature data is monitored in real time by the temperature monitor 20.

[0033] The module maintenance operation process is as follows: after the fixing bolt 19 is loosened, the refrigeration module 4 is pulled outward to drive the adjusting block 12 to move along the sliding groove 11. When the limiting rod 14 is disengaged from the locking position, the limiting spring 13 rebounds to release the adjusting block 12, at this time, the adjusting block 12 is held and rotated, and the refrigeration module 4 is flipped outward with the pivot 15 as the fulcrum. At this time, the internal space of the heat dissipation frame 3 is completely exposed, and the dustproof module 8 slot parallel to the combined fan 18 of the fan module 7 can be seen. The dustproof module 8 is extracted upward to remove the vertical strip-shaped dust screen 17 inside for cleaning or replacement. The combined fan 18 of the fan module 7 is also designed in a plug-in manner, and the fan blade unit can be directly replaced after disassembly. When the refrigeration module 4 needs to be repaired, it only needs to be kept in the flipped state, and the condenser pipe 5 is completely exposed, and through the conduit 10, quick dredging or pipeline maintenance can be achieved. After maintenance is completed, reverse operation can restore the working position of each module, and the limiting rod 14 automatically locks the adjusting block 12.
