The current mobile devices, personal computers, servers, and communication chassis are all due to the improvement of computing performance, and the heat generated by the internal computing unit is also increasing. Relatively, a cooling unit is needed to assist in cooling. Most companies use radiators, Cooling elements such as heat pipes and vapor chambers are used together with fans for auxiliary heat dissipation, and when a large area is required for heat dissipation, the vapor chamber is used to absorb heat and cooperate with radiators and cooling fans for forced heat dissipation. To prevent the occurrence of thermal resistance, the vapor chamber is a flat plate with a chamber for vapor-liquid circulation inside to conduct heat conduction, and to prevent the flat vapor chamber from expanding when it is under pressure or heated Or deformed, a plurality of supporting columns are set in the chamber as a chamber for supporting the chamber.

The vapor chamber is a surface-to-surface heat transfer, and in the above description, multiple support columns are provided to prevent the vapor chamber from being heated and expanded or crushed and deformed by external forces, but additional manufacturing hours and manufacturing costs are required in the manufacturing process (Support cylinder), and if a plurality of copper pillars are used to combine sintered rings, the copper pillars are used as supports, and the sintered ring is only used as a reflow cycle. It is difficult to control the flatness of the bottom, or use multi-groove copper pillars. The copper pillars also serve as supports and recirculation functions, and the flatness of the bottom is also difficult to control. the

Although the original technology solves the problems such as deformation, it increases the man-hours and costs of manufacturing, and it is difficult to control the flatness of the bottom. Therefore, it is still necessary to conduct in-depth discussions on how to reduce the manufacturing cost. the
