Abstract

A heat dissipating device includes a substrate, a plurality of fins, and a heat pipe. The substrate has a plurality of retaining holes. Each of the fins includes a heat dissipating sheet and a retaining sheet extended from the heat dissipating sheet and passing through one of the retaining holes. The heat pipe is disposed on the fins.

Description

technical field [0001] The invention mainly relates to a heat dissipation device, especially a heat dissipation device with fins. Background technique [0002] The current manufacturing method of the heat sink generally uses solder paste to fix the fins and heat pipes on the substrate by welding. However, in consideration of environmental protection, the structure of the heat sink needs to be redesigned to reduce the use of solder paste. In addition, most of the above soldering steps are performed manually, which also increases the manufacturing cost of the heat sink. [0003] Therefore, it is necessary to provide a heat dissipation device to solve the above problems. Contents of the invention [0004] In order to solve the shortcomings of the above-mentioned known technologies, the purpose of the present invention is to provide a heat sink, and the heat sink can be assembled without using solder paste. [0005] In order to achieve the above object, the present inventio...
