Description

Heat sink compression structure

A heat sink compression structure, in particular a heat sink compression structure that ensures that a vapor chamber of a heat sink having a curved structure is curved while still retaining its complete vapor chamber.

The current uniform temperature plate and flat heat pipe system are commonly used for heat dissipation components used in various fields of heat dissipation. The main principle of the temperature equalization plate and the flat plate heat pipe is to establish a vacuum airtight chamber through the interior and set in the chamber. Capillary structure and working fluid, the working fluid in the vacuum environment, its boiling point is lower than the general environment, so the vapor-liquid circulation can be quickly carried out in the chamber, so the effect of rapid large-area heat conduction or remote heat conduction is achieved. However, in order to meet the application of various fields in various fields, the uniform temperature plate or the flat plate heat pipe is no longer only a traditional flat shape.

Shape, in order to meet the application; while the uniform temperature plate or flat heat pipe is shaped, it will inevitably cause the internal chamber to be used as a vapor channel to be crushed and deformed, thereby affecting the efficiency of the vapor-liquid circulation. Some manufacturers use a copper column as a support, but a support with a convex column shape cannot be placed at an angle with an R angle or an excessive bending angle, so that the chamber is still unable to be supported and collapse or narrow. However, the capillary structure of the curved portion may also cause warping or falling off due to bending, so that the heat transfer efficiency of the uniform temperature plate or the flat heat pipe is greatly reduced and the disability is lost. Therefore, how to improve the aforementioned lack of the prior art is in the field. The first goal of the industry.
