Abstract

The invention provides a heat radiation assembly and an electric device, wherein the heat radiation assembly comprises: a screening element which is arranged with a through hole thereupon and is in electrical connection with ground copper of PCT board, the PCT board being equipped with heat radiation electrical elements; a heat tube which is positioned on the through hole, the heat tube being in electrical connection with the screening element, together, the heat tube, the PCT board and the screening element constituting an electromagnetic screen cover which can hold a heat radiation electrical element; an elastic thermal interface material which is arranged between the heat tube and the heat radiation electrical element and is cemented to the heat tube and the heat radiation electrical element. In the technical solution herein, the through hole on the screen element cements the thermal interface material on the heat radiation electrical element and the heat tube, which enables heat of the heat radiation electrical element to be transmitted to the heat tube via thermal interface material, thus reducing heat resistance of the heat radiation assembly and shortening heat transmission path between the heat radiation electrical element and the heat tube.
