When in use, the inverter body 3 is placed above the water tank 6 arranged in the base 1, and a heat sink 20 is arranged in the water tank 6. The upper surface of the heat sink 20 is in full contact with the bottom surface of the inverter body 3. The inverter body 3 will generate heat during use. Through the close contact between the two, the heat can be conducted from the inverter body 3 to the heat sink 20 more quickly. The heat sink 20 is made of aluminum alloy and has good thermal conductivity to promote heat conduction.

[0026] A card slot 14 is provided on the lower surface of the connecting block 2, and the card slot 14 is communicated with the hole 13. A protective net 15 is fixedly connected in the card slot 14. Holes 2 18 are provided on both sides of the water tank 6, and the two holes 18 are fixedly connected to the connecting pipe 1 5 and the connecting pipe 3 10 respectively. The fan 11 is started. When the coolant flows through the spiral tube 8, the airflow generated by the fan 11 prompts the hot air to move quickly and then be discharged downward through the protective net 15. The discharged air contacts the surface of the inverter body 3, which enhances the convection heat dissipation and accelerates the heat transfer, thereby effectively dissipating the heat of the coolant and the inverter body 3.

[0027] A card slot three 17 is provided on the upper surface of the water tank 6, and the card slot three 17 is fixedly connected to the heat sink 20.

[0028] Working principle:

[0029] When in use, the inverter body 3 is placed above the water tank 6 provided in the base 1. The water tank 6 is provided with a heat sink 20. The upper surface of the heat sink 20 is in full contact with the bottom surface of the inverter body 3. The inverter body 3 generates heat during use. Through the close contact between the two, the heat can be transferred from the inverter body 3 to the heat sink 20 more quickly. The heat sink 20 is made of aluminum alloy and has good thermal conductivity to promote heat conduction. The water tank 6 is provided with a coolant. The coolant is in full contact with the fins at the lower end of the heat sink 20, and the heat on the fins can be effectively absorbed.

The cooling liquid is then drawn out and circulated through the connecting pipe 2 7, the spiral pipe 8 and the connecting pipe 3 10, and the fan 11 is started. When the cooling liquid flows through the spiral pipe 8, the airflow generated by the fan 11 causes the hot air to move quickly and then be discharged downward through the protective net 15. The discharged air contacts the surface of the inverter body 3, thereby enhancing the convection heat dissipation and accelerating the heat transfer, thereby effectively dissipating the heat of the cooling liquid and the inverter body 3. The spiral design of the spiral pipe 8 increases the heat dissipation area. This device can effectively reduce the operating temperature of the inverter body 3 and has a large heat dissipation range, which is particularly important for the inverter body 3 under long-term operation and high load.
