Electric energy transmission device with heat radiation function

The invention relates to an electric energy transmission device with a heat radiation function. The electric energy transmission device comprises an encapsulation casing, a heat conducting sheet and an active element, wherein the heat conducting sheet is arranged on the encapsulation casing, the active element is arranged in the encapsulation casing, and the encapsulation casing and the heat conducting sheet are made of foam aluminum materials with high fire-resistant, insulation and heat conduction capability. The electric energy transmission device has the advantages that the encapsulation casing and the heat conduction sheet are made of the foam aluminum materials with the high fire-resistant, insulation and heat conduction capability, the heat generated by the active element can be effectively conducted out, the heat conducting area of the encapsulation casing can be increased through the T-shaped heat conducting sheet and the foam aluminum in through hole structures, and the effective heat radiation can be realized.
