Press fitting method for heat pipe and heat sink

Abstract

A press fitting method for heat pipe and heat sink includes the following steps. a) At least a heat pipe and a heat sink conducting heat to the heat pipe are provided. The heat sink is one of a heat conducting plate or a fin module. The heat sink has a groove for receiving the heat pipe. b) The heat pipe is placed into the groove. c) An end of the heat pipe or the heat pipe under the fins is pressed by a press mold so as to be deformed and fit to the groove as one. Through the above steps, an efficient and quick method is provided and the heat pipe will be tightly fitted to the heat sink so as to achieve a better heat dissipation.
