Composite radiator

The utility model provides a composite radiator, contains a heat conduction core piece and an at least heat pipe. Heat conduction core piece has a top surface and a bottom surface, an accommodation space is established to the top surface fovea superior, and the bottom of accommodation space sets up an at least blind hole, and the inner wall of accommodation space sets up an at least caulking groove, and the caulking groove is extended towards the bottom of accommodation space direction by the top surface. The heat pipe has at least one and inlays the section of establishing and one insert the section of establishing, inlays the caulking groove of the section of establishing embedding heat conduction core piece to insert the section of establishing and insert the blind hole. Through the setting of accommodation space, the weight of heat conduction core piece can alleviate by a wide margin, and the setting of heat pipe can ensure again that the heat -conduction efficiency of heat conduction core piece is promoted.
