1. A heat radiation structure of an inverter, comprising:
a heat radiator for radiating heat from a heating element of the inverter, and
a heat radiation fan for air-cooling the heat radiator;
wherein the heat radiator comprises a plurality of heat radiation fins able to be air-cooled;
wherein a number of the heat radiator is at least two, and two adjacent heat radiators are a first heat radiator and a second heat radiator respectively; and wherein the heat radiation fan is provided between the first heat radiator and the second heat radiator,
wherein, the heat radiator comprises a heat radiation substrate, and the heat radiation fins are provided on the heat radiation substrate, wherein a plane defined by a base of the heat radiation fan is not closer to the heat radiation substrate than a plane defined by tops of the heat radiation fins to the heat radiation substrate.
