In the AC - DC - AC variable speed wind power generation system, the control technology of the inverter is the key. The inverter directly uses the voltage synchronization signal of the power grid as the tracking signal of the output current of the inverter, which can make the output current track the voltage of the grid quickly. Inverters are used in solar power facilities to convert direct current generated by solar panels into alternating current that can be used in power grids. These two applications are faced with severe cooling challenges that require complex thermal management solutions, and become increasingly difficult as power density increases.

 

Under the condition that the existing heat dissipation can not be satisfied, the reform of heat dissipation technology is becoming more and more serious. Liquid cooling technology as a new type of heat dissipation technology has also attracted more and more attention from experts. Water cooling has a quiet, sustainable, high cooling rate and other characteristics, in addition to the common use of computer heat dissipation, but also widely used in power, medical, led and other industries, can be said that water cooling has gradually penetrated into the vast majority of heat dissipation.
