Description

Thermal module and its manufacturing method

The invention relates to a heat conducting module and a manufacturing process thereof, and more particularly to a heat conducting module for forming a molten aluminum material coated aluminum heat pipe by a die casting process and a manufacturing method thereof.

According to the superconducting elements used in the past for heat dissipation or heat transfer, such as heat pipes, etc., which pass through the internal vacuum environment to provide a working fluid injected into the interior to generate liquid due to heat. The vapor phase changes, and then transfers heat with steam, and then returns to a liquid state due to cold to recirculate. In the past, a plate type heat pipe having a plurality of heat pipes disposed in a solid or hollow metal plate or a heat pipe having a circular tubular shape and being subjected to a pressing process such as rolling or pressing has been used.

Thermal resistance problem. In particular, in the embodiment in which the solid metal plate heating pipe is inserted or buried, it is difficult to control the tolerance by the penetration mode. Too loose must add a medium such as a thermal paste to reduce the gap, and too tight to increase the heat pipe during the penetration process. Difficulty; if it is buried, it is easy to cause problems such as heat transfer between the metal plate and the heat pipe (usually the pipe wall of the heat pipe is made of copper).
