[0021] See also Figure 1-7 A frequency converter water cooling plate includes a cooling plate 1 and a water cooling pipe 3. A plurality of heat conducting plates 2 are fixed on the surface of the cooling plate 1. Two side plates 4 are fixed on the left side of the cooling plate 1. A connecting pipe 5 is fixed on the surface of the side plate 4. A lower purification shell 6 is fixed to the bottom of the connecting pipe 5. An upper purification shell 7 is detachably connected to the upper part of the lower purification shell 6. A groove 8 is provided on the inner wall of the lower purification shell 6 and the upper purification shell 7. A filter screen 9 and a filter element 10 are slidably connected inside the groove 8. Two fixed shells 11 are fixed on the surface of the cooling plate 1. The front side of the fixed shell 11 is detachable. A movable housing 12 is provided, and a connecting plate 15 is fixed to the top and bottom of the movable housing 12. A slot 16 is provided on the surface of the connecting plate 15. A mounting shell 17 is fixed to the top and bottom of the fixed housing 11. A limit spring 18 is fixed to the inner wall of the mounting shell 17. A wedge block 19 is fixed to one end of the limit spring 18. An operating rod 20 is fixed to one end of the wedge block 19. The operating rod 20 passes through the mounting shell 17. Two positioning blocks 13 are fixed to the surface of the water-cooling tube 3. Positioning grooves 14 are provided on the inner walls of the fixed housing 11 and the movable housing 12.

[0022] The coolant can be transported to the inside of the connecting pipe 5 through the lower purification shell 6 and the upper purification shell 7, and is transported to the inside of the water-cooling pipe 3 by the connecting pipe 5, so that the water-cooling pipe 3 can absorb the heat generated by the cooling plate 1 and the heat conducting sheet 2, thereby achieving a cooling effect on the cooling plate 1. At the same time, the heat conducting sheet 2 can also increase its contact area with the air, thereby further improving the cooling effect of the water-cooled plate. When the coolant enters the lower purification shell 6 and the upper purification shell 7, the coolant will first be filtered by the filter screen 9, and then filtered by the filter element 10 before it can continue to be transported to the inside of the connecting pipe 5. The filter screen 9 can intercept most of the larger particles, thereby reducing the burden on the filter element 10, and the filter element 10 can further intercept the cooling Smaller impurities and particulate matter in the liquid can ensure the cleanliness of the coolant through this double-stage filtration, which helps to keep the flow of the cooling system unobstructed and reduce the blockage of impurities inside the water-cooling pipe 3, thereby maintaining high heat exchange efficiency. When the water-cooling pipe 3 needs to be disassembled and repaired, the operating rods 20 on both sides are pulled to allow the wedge block 19 to disengage from the slot 16. At this time, the movable shell 12 can be moved outward to separate the movable shell 12 from the surface of the fixed shell 11, thereby releasing the limiting effect on the front part of the water-cooling pipe 3, allowing the operator to directly pull the water-cooling pipe 3 forward to complete the disassembly of the water-cooling pipe 3 and the cooling plate 1, thereby achieving the removal operation of the water-cooling pipe 3 without the aid of tools.

[0023] Furthermore, a fastening shell 21 is embedded and fixed on the inner wall of the fixed housing 11 and the movable housing 12, a clamping spring 22 is fixed on the inner wall of the fastening shell 21, and a clamping plate 23 is fixed on one end of the clamping spring 22;

[0024] When the surfaces of the fixed shell 11 and the movable shell 12 are fitted together, the two side clamps 23 will contact each other and compress the clamping spring 22, so that the clamping spring 22 can provide an additional contact force between the two side clamps 23, making it difficult for the liquid to pass through between the two side clamps 23, thereby preventing the coolant from leaking from the gap between the fixed shell 11 and the movable shell 12.

[0025] Furthermore, a first sealing ring 24 is fixed on the surface of the fastening shell 21, and a first sealing groove 25 for cooperating with the first sealing ring 24 is opened on the surface of the water-cooling tube 3;

[0026] When the water-cooling pipe 3 drives the positioning block 13 to be placed into the positioning groove 14 , the first sealing ring 24 will fit tightly with the inner wall of the first sealing groove 25 , thereby improving the sealing performance after the water-cooling pipe 3 is installed between the fixed housing 11 and the movable housing 12 .

[0027] Furthermore, a plurality of assembly plates 28 are fixed on the surface of the lower purification shell 6 and the upper purification shell 7, and through holes are opened on the surface of the assembly plates 28;

[0028] After the upper purification shell 7 is placed on the surface of the lower purification shell 6 , bolts can be passed through the through holes and nuts can be installed to fix the upper purification shell 7 and the lower purification shell 6 .

[0029] Furthermore, a sealing gasket 29 is fixed to the top of the lower purification shell 6, a closed groove for use with the sealing gasket 29 is opened at the bottom of the upper purification shell 7, a second sealing ring 30 is fixed to the inner wall of the upper purification shell 7, and a second sealing groove 31 for use with the second sealing ring 30 is opened on the surface of the connecting pipe 5;

[0030] When the lower purification shell 6 and the upper purification shell 7 are closed, the sealing gasket 29 and the second sealing ring 30 are both in a compressed state, so that the upper purification shell 7 and the lower purification shell 6 can obtain a sealing effect through friction, thereby preventing leakage when the coolant circulates.

[0031] Furthermore, four guide rods 26 are fixed on the surface of the movable housing 12, and four guide grooves 27 are opened on the surface of the fixed housing 11;

[0032] When the movable housing 12 is mounted on the surface of the fixed housing 11 , the guide rod 26 enters the guide groove 27 , thereby guiding the movable housing 12 and enabling the movable housing 12 to be more accurately mounted on the surface of the fixed housing 11 .

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
