[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example: Figures 1-4 As shown, this utility model provides a technical solution for a heat dissipation device for a high-voltage transformer, including a housing 1, a transformer body 2 disposed inside the housing 1, two conduits 3 fixedly connected to one side of the housing 1, the conduits 3 being flexible hoses, and an exhaust fan 4 disposed inside the housing 1, the exhaust fan 4 being electrically connected to a power supply, the exhaust fan 4 being located at the pipe opening of the conduits 3, a refrigeration box 5 disposed on one side of the housing 1, a heat exchange tube 6 installed inside the refrigeration box 5, the heat exchange tube 6 having an S-shaped spiral cross-section, and the two conduits 3 respectively being connected to both ends of the heat exchange tube 6;

[0022] The refrigeration chamber 5 is filled with cooling water. The air inside the shell 1 is transported to the heat exchange tube 6 through one of the ducts 3 by the exhaust fan 4, and then transported to the shell 1 through the other duct 3. This completes the sealed airflow circulation. When the airflow passes through the heat exchange tube 6, the cooling water outside the heat exchange tube 6 exchanges heat with the gas inside the heat exchange tube 6, thereby achieving the effect of heat dissipation and cooling of the gas inside the shell 1. The gas inside the shell 1 also carries away the heat emitted by the transformer body 2. The transformer body 2 is a high-voltage transformer, and the shell 1 is the outer shell of the transformer body 2.

[0023] like Figures 2-4 As shown, the housing 1 has a circulation chamber 7 and an installation chamber 8 inside. The transformer body 2 is installed inside the installation chamber 8. A partition 9 is installed on the inner wall of the installation chamber 8. The partition 9 is sleeved on the outside of the transformer body 2. The interfaces of the two conduits 3 are located above and below the partition 9, respectively. Two sets of through holes 10 are formed between the circulation chamber 7 and the installation chamber 8. The two sets of through holes 10 are located above and below the partition 9, respectively.

[0024] The mounting cavity 8 is divided into two compartments by the partition 9. Both compartments are connected to the circulation cavity 7. In this way, the gas in one compartment is discharged and the cooled gas is transported to the other compartment. The gas flows between the two compartments through the circulation cavity 7, thereby increasing the flow range and heat dissipation range of the gas inside the mounting cavity 8.

[0025] like Figures 1-4 As shown, the top and bottom walls of the mounting cavity 8 are fixedly connected with support blocks 11 that are distributed at equal intervals. The upper and lower sets of support blocks 11 are in contact with the upper and lower parts of the transformer body 2, respectively.

[0026] The support block 11 is used to support the transformer body 2, thereby increasing the heat dissipation range of the transformer body 2.

The refrigeration chamber 12 is located between the two air chambers 13. The heat exchange tube 6 is fixedly connected between the two air chambers 13 and is located inside the refrigeration chamber 12. The movable ends of the two conduits 3 are fixedly connected to the two air chambers 13 respectively.

[0028] The gas in the shell 1 enters one of the gas chambers 13 through the conduit 3, then passes through the cooling chamber 12 through the heat exchange tube 6 and is delivered to another gas chamber 13, and then the gas is introduced into the shell 1 through another conduit 3.

[0029] like Figure 4 As shown, the top wall of the housing 1 inside the cooling chamber 12 has an installation opening, and a sealing groove is formed at the top of the installation opening. A sealing cover 15 is installed in the sealing groove, and a sealing ring is provided between the sealing cover 15 and the sealing groove. The sealing ring is a rubber ring. Threaded holes are opened at the four corners of the upper part of the sealing cover 15, and threaded rods 14 are connected to the threads. Four threaded grooves are opened on the inner wall of the sealing groove of the housing 1, and the four threaded rods 14 are respectively threaded to the four threaded grooves. The support block 11 on the top wall of the cooling chamber 12 is fixedly connected to the bottom of the sealing cover 15.

[0030] The sealing cover 15 facilitates the opening of the housing 1, and the sealing ring is used to increase the sealing between the housing 1 and the sealing cover 15.

[0031] like Figure 1 one Figure 3 As shown, the upper part and one side of the refrigeration box 5 are respectively connected to the water inlet pipe 16 and the water outlet pipe 17. The end of the water inlet pipe 16 is provided with a pipe cap, and the water outlet pipe 17 is provided with a switch valve.

[0032] Cooling water is supplied to the refrigeration chamber 5 through the inlet pipe 16 and discharged from the refrigeration chamber 5 through the outlet pipe 17. The pipe cover is used to open or close the inlet pipe 16, and the switch valve is used to open and close the outlet pipe 17.

[0033] like Figure 3 and Figure 4 As shown, the bottom wall inside the cooling chamber 12 is formed with a heat dissipation vent, and a heat conduction plate 18 is installed on the heat dissipation vent. The support block 11 on the bottom wall of the cooling chamber 12 is fixedly connected to the upper part of the heat conduction plate 18. A through-hole is opened at the center of the support block 11, and a heat conduction rod is installed in the inner hole. The heat conduction rod is fixedly connected to the heat conduction plate 18.

[0034] The heat-conducting plate 18 is used to improve the heat conduction effect from the transformer body 2 to the outer shell 1.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
