Description

Technical Field

[0002] The explosion-proof inverter applies frequency conversion technology and microelectronics technology to control the power transmission elements of AC motors by changing the frequency and amplitude of the motor's working power supply. The inverter is mainly composed of rectification (AC to DC), filtering, inversion (DC to AC), braking unit, drive unit, detection unit and microprocessor unit.

[0003] The inverter generates a lot of heat during operation and needs to be cooled by a cooling device. A water cooling device is a commonly used cooling device for the inverter. However, the coolant of the existing water cooling device will produce a large amount of impurities during long-term circulation. These impurities can easily damage the water pump and affect the service life of the water pump. Utility Model Content

[0004] (1) Technical problems solved

[0005] The technical problem to be solved by the utility model is that the existing water cooling device cannot filter the coolant, which easily causes damage to the water pump.

[0006] (2) Technical solution

[0007] The heat dissipation device is connected with the heat dissipation device through the channel, and the channel is connected with the channel of heat dissipation device through which the heat is dissipated, and the channel is connected with the channel of heat dissipation device through which the heat is dissipated.

[0008] As an improvement, a serpentine heat dissipation pipe is fixedly connected in the heat dissipation box, and both ends of the serpentine heat dissipation pipe are fixedly connected to the cold water inlet pipe and the drain pipe respectively.

[0009] As an improvement, the heat dissipation box is fixedly connected to a heat dissipation fan on one side of the serpentine heat dissipation tube.

[0010] As an improvement, the lower end of the filter tank is threadedly connected to a sewage hopper.

[0011] As an improvement, the lower end of the sewage hopper is fixedly connected to a sewage pump, and the lower end of the sewage pump is fixedly connected to a sewage pipe.

[0012] As an improvement, the heat dissipation fins are provided with evenly arranged heat dissipation holes.

[0013] (3) Beneficial effects

[0014] The advantages of the present invention over the prior art are that the contact area with the cold water can be further increased through the heat dissipation fins. After the cold water absorbs the winding beam, the cold water in the water-cooling box is pumped into the filter tank under the operation of the diversion pump. After the coolant is filtered through the filter cylinder, it is discharged into the serpentine heat dissipation pipe through the drain pipe. The serpentine heat dissipation pipe further dissipates the heat of the internal coolant, and finally the cold water returns to the water-cooling box from the cold water inlet pipe.
