Radiating module

Abstract

The heat elimination module includes heat pipe, fastener combined to evaporation end of heat pipe, and heat elimination fins combined to condensation end of heat pipe. The fastener includes a heat transfer part, and fixed part extended from the heat transfer part. One surface of the heat transfer part is jointed to the evaporation end of heat pipe, and the other related surface is in use for contacting a heating element.

Description

【Technical field】 [0001] The invention relates to a heat dissipation module, in particular to a heat dissipation module of heating electronic components. 【Background technique】 [0002] Existing heat dissipation modules generally include a heat absorbing plate, a heat pipe, and a plurality of heat dissipation fins. The heat absorbing plate is attached to a heating electronic component on a circuit board to absorb the heat generated by the heating electronic component and dissipate the heat. Transfer to the heat pipe, through the heat pipe to the heat dissipation fins, and the heat is dissipated by the heat dissipation fins. [0003] The heat pipe is generally installed in a groove provided on the heat absorbing plate, or fixed to the heat absorbing plate through a fixing device. An existing fixing device for fixing a heat pipe to a heat absorbing plate includes a cover plate attached to the heat absorbing plate and four elastic arms fixed to the four corners of the cover pl...

Problems solved by technology

[0005] However, the deformation of the fixing part is mainly concentrated in the joint area between the elastic arm and the cover plate, that is, the position close to the four corners of the heat absorbing plate, so that the acting force is mainly concentrated on the four corners of the heat absorbing plate, and the force on the middle part of the heat absorbing plate is mainly concentrated. The force is small, so that the heat-absorbing plate deforms with the two opposite sides of the heating element as the fulcrum, and the middle part of the heat-absorbing plate is separated from the heating element, which affects the joint between the heating element and the heat-absorbing plate, and increases the contact between the heating element and the heat-absorbing plate. The thermal resistance between the heat plates reduces the heat transfer effect. In this case, even if a heat conduction medium is filled between the heating element and the heat absorbing plate, the heat transfer effect between them cannot be greatly improved.
