[0026] First, the heat sink 7 quickly absorbs the high temperature generated by the long-term operation of the high-voltage inverter. Then, by starting the heat sink 13, the heat absorption tube on the output end thereof extracts the heat absorbed by the heat sink 7 through the heat absorption cover 14, and discharges the heat to the outside through the heat dissipation port on the heat exhaust seat 15, so as to achieve the effect of rapid heat dissipation for the high-voltage inverter.

[0028] The utility model provides the fixing column 8, the card slot 9, the card block 10, the support rod 11 and the top seat 12 and other components for use together, so as to facilitate the support and placement of the heat dissipation structure, and also facilitate the disassembly and installation of the top seat 12, and facilitate the inspection and maintenance of the heat sink 13 on the top seat 12.

[0032] When in use, first, the heat sink 7 is used to quickly absorb the high temperature generated by the long-term operation of the high-voltage inverter. Then, by starting the heat sink 13, the heat absorption pipe on the output end thereof is used to extract the heat absorbed by the heat sink 7 through the heat absorption cover 14, and the heat is discharged to the outside through the heat dissipation port on the heat exhaust seat 15, so as to achieve the effect of rapid heat dissipation for the high-voltage inverter. Moreover, when it is necessary to disassemble and replace the heat sink 7, the connecting plate 6 is taken by hand and moved upward, and at the same time, the connecting plate 6 drives the fixing blocks 5 on both ends to be separated from the fixing grooves 4 provided on the mounting plate 1, so that the heat sink 7 can be disassembled for cleaning and replacement, thereby facilitating the improvement of the subsequent heat dissipation effect for the high-voltage inverter.

[0033] Then, when the heat sink 13 needs to be inspected and maintained, the top seat 12 is taken by hand and moved upward, so that the top seat 12 drives the block 10 on the bottom of the support rod 11 to disengage from the corresponding slot 9 on the top surface of the fixing column 8, thereby facilitating the removal of the top seat 12 and facilitating the inspection and maintenance of the heat sink 13.
