The existing inverter radiator inverter heat dissipation system mainly comprises a radiator, a cooling fan, heat-conducting silicone grease and other materials, and the existing inverter heat dissipation modes mainly comprise two types: natural cooling and forced air cooling. Natural cooling means that under the condition that no external auxiliary energy is used, the purpose of achieving temperature control by radiating heat of a local heating device to the surrounding environment is achieved, and the purpose generally comprises three main heat transfer modes of heat conduction, convection and radiation, wherein the convection is mainly in a natural convection mode; forced air cooling is a method of taking away heat emitted from devices by forcing air around the devices to flow mainly with the aid of fans and the like.
