Abstract

In a heat-conducting assembly for heat pipes of different diameters and a heat sink having such assembly, the heat-conducting assembly includes a heat-conducting base, a set of first heat pipes and a set of second heat pipes. A heat-conducting surface of the heat-conducting base is provided with a plurality of accommodating troughs. The diameter of the set of second heat pipes is smaller than that of the set of first heat pipes. The first heat pipe and the second heat pipe of different diameters are disposed in the accommodating troughs respectively. The heat pipes penetrate a plurality of fins to form the heat sink. With this arrangement, the ratio of heat pipes arranged on the heat-conducting surface can be increased and the heat-conducting efficiency thereof can be improved.
