Background

An inverter is an electronic device for converting direct current into alternating current. It is commonly used in various power systems, such as solar power generation systems, wind power generation systems, electric vehicles, and some industrial facilities. The main function of the inverter is to convert the direct current power supply into a usable alternating current power supply for various electric appliances and devices. The output of the inverter typically has adjustable frequency, voltage, current, etc. parameters to meet the needs of different devices. In solar and wind power generation systems, an inverter converts direct current generated by a solar panel or wind turbine into alternating current for supply to a home, industrial facility, or grid for use.

However, as the power density of the electronic device increases, more and more heat is generated in the running process of the electronic device such as the inverter, the high temperature not only affects the performance and the service life of the electronic device, but also may cause damage or performance degradation of the electronic device, and the conventional heat dissipation modes usually adopt a fan to dissipate heat or a heat dissipation fin to dissipate heat, so that the heat dissipation modes have poor effects, and are difficult to meet the heat dissipation requirements of the high-power density device.
