Problems solved by technology

[0004] In addition, there are also operators who apply heat-conducting adhesive between the heat-dissipating pipe and the heat-dissipating body, and use gluing processing technology to combine the heat pipe and the heat-dissipating body. Polymer materials will lose their adhesive effect due to time curing or deterioration, resulting in gaps and affecting heat conduction performance. Therefore, it is necessary to improve the above shortcomings

Abstract

The invention discloses a method for tightly fitting a heat pipe with a heat sink, comprising the following steps: a) providing at least one heat pipe and a heat sink for conducting heat with the heat pipe, wherein the heat sink is a heat conduction plate or a fin group and is provided with a groove or a through hole for assembling and containing the heat pipe; b) putting the heat pipe into the groove or the through hole, and preparing a pressing die; c) causing the pressing die to correspond to the heat pipe in a stamping groove or a heat pipe section between two fins, stamping and applying force on one end of the heat pipe or the heat pipe section to accelerate the peripheral wall of the heat pipe to deform or hunch to the through hole for deformation; and pressing the peripheral wall with the groove or the through hole to be combined into a whole. According to the above characteristics, quick and effective combination efficiency is provided, and the heat pipe and the heat sink are tightly combined to satisfy the requirement of the heat source on high-efficiency heat dissipation.

Description

technical field [0001] The invention relates to a method for tight fitting of a heat pipe and a heat sink, especially to the technical field of heat dissipation for devices such as computers, electronics or diode lamps or industries thereof, and a tight connection method thereof. Background technique [0002] In order to provide better heat dissipation performance of heat sinks such as computers, electronics or diode lamps, heat sinks must cooperate with heat pipes. Generally, heat sinks are commonly used as heat sinks (or heat sink bases) or fin modules. The heat source is thermally bonded, and the heat conduction is quickly removed through the heat pipe to meet the heat dissipation requirements of the heat source. [0003] The known method of fastening the heat pipe and the radiator is to use solder to weld the joint surface of the heat pipe and the fins, but this welding method is not only environmentally friendly but also extremely cumbersome, not only must apply solder ...
