Abstract: A heat sink assembly is characterized by comprising a base consisting of an aluminum casting and a copper base plate, a heat sink consisting of a plurality of aluminum heat fins, and at least a heat guide; wherein at least a groove is provided on each of the plurality of heat fins according to the quantity of said heat guide for passing the dissipation part of each said at least a heat guide, a cavity is opened on said aluminum casting for said copper base plate housing, and at least a trough is formed on the top surfaces of said copper base plate and said aluminum casting for placing the heat conduction part of each said at least a heat guide, and said copper base plate is placed against the heat source to transfer the heat through said base to said heat guide and then to said heat sink, so that the heat can be dissipated rapidly through said plurality of heat fins. In addition, the weight of the heat sink assembly is decreased, further more, the manufacturing costs reduced.

Abstract translation: 散热器组件的特征在于包括由铝铸件和铜基板组成的基座，由多个铝散热片组成的散热片和至少一个热导; 其特征在于，根据所述导热体的数量，在所述多个散热片的每一个上设置至少一个槽，用于使每个所述至少一个导热体的散热部分通过，所述铝铸件上的所述铜基板 壳体，并且至少一个槽形成在所述铜基板和所述铝铸件的顶表面上，用于放置每个所述至少一个导热器的导热部分，并且所述铜基板抵靠热源放置以转移 所述热量通过所述底座到所述导热件，然后到所述散热器，使得热能够通过所述多个散热片快速消散。 此外，散热器组件的重量减少，进一步降低了制造成本。
