Abstract
A heat sink includes a fixing base, a plurality of heat pipes and a fixing body. The bottom surface of the fixing base is provided with a connecting plane and extends upwards to form a fixing arm. The fixing arm is provided with a plurality of first grooves. The fixing body is provided with a plurality of second grooves and combined with the fixing arm. The second grooves correspond to the first grooves for cooperatively receiving and clamping the upper edges of the evaporating sections of the heat pipes. The evaporating section of the heat pipe is provided with a contacting plane and an adhering plane. The contacting planes of the evaporating sections are adjacent to each other and the evaporating sections are fixed to the connecting plane of the fixing base. With this arrangement, the juxtaposed heat pipes can be assembled with the fixing base. Further, the condensing section of the heat pipe penetrates a plurality of fins to form the heat sink.
