AI Technical Summary

Technical Problem

In existing inverter cooling devices, water tanks are placed on both sides of the inverter, causing heat to accumulate. The air blown in by the fan may circulate hot air without being cooled, resulting in poor cooling effect.

Method used

The water tank is placed behind the frequency converter, and a combination of air cooling and liquid cooling is used. The frequency converter is cooled by the liquid storage tank and liquid cooling heat sink. The air generated by the fan blows to the frequency converter through the air guide channel in the liquid storage tank, and the liquid cooling heat sink further cools the frequency converter inside.

Benefits of technology

It effectively prevents hot air circulation, improves the heat dissipation efficiency and cooling effect of the frequency converter, and increases the working stability of the frequency converter.
