Problems solved by technology

[0002] Power equipment mainly includes power generation equipment and power supply equipment. Power generation equipment is mainly power plant boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment is mainly transmission lines of various voltage levels, transformers, contactors etc. Power equipment in normal operation will generate heat due to the effect of current and voltage. When there is a defect or fault in the power equipment, the temperature of the defect or fault part will produce abnormal changes, which will cause local heating. Or the cooling of the entire power equipment will cause accidents such as fires, and even cause grid accidents and paralyze the grid.
Therefore, it is necessary to dissipate heat from some power equipment that is prone to heat. Traditional power equipment cooling devices use fans to dissipate heat from power equipment, and the heat dissipation effect is poor.
