The present invention provides a heat radiation structure of power converter and an electronic device, and relates to the power converter heat radiation technology field. The heat radiation structure of the power converter and the electronic device can effectively reduce the temperature of the local hot spots of the surface of a power converter and reduce the temperature rising of a housing. The heat radiation structure of the power converter provided by the embodiment of the invention comprises the power converter, the power converter is coated with an embedding layer, the embedding layer comprises heat conduction materials, the housing is arranged at the external portion of the embedding layer, and an air interlayer is formed between the housing and the embedding layer. The heat radiation structure of the power converter and the electronic device can be used for a power converter.
