摘要
A vapor chamber includes a main body. The main body includes a base plate and a top plate. The base plate includes a plate body, a peripheral frame and a plurality of supporting pillars. The plate body has a surface. The peripheral frame is disposed on the surface of the plate body. The surface and the peripheral frame together define a first space. The first space is configured to accommodate a working fluid. The supporting pillars are located in the first space and are distributed on the surface of the plate body. The supporting pillars, the plate body and the peripheral frame are of an integrally-formed structure. The top plate abuts against the peripheral frame and the supporting pillars to seal up the first space.

This application is a Divisional Application of the U.S. application Ser. No. 17/585,597, filed Jan. 27, 2022, now U.S. Pat. No. 11,985,796, which claims priority to Taiwanese Application Serial Number 110110908, filed Mar. 25, 2021, all of which are herein incorporated by reference in their entireties.
The present disclosure relates to methods to manufacture vapor chambers.
With the rapid advancement of electronic technology, the functions of various electronic products have been greatly enhanced as well. Inevitably, in order to cope with the enhancement of the functions of the electronic products, the requirement of heat dissipation to the processors inside the electronic products has also been increased. Therefore, the application of vapor chambers has become more popular.
In practical applications, a vapor chamber works to deliver away the heat produced during the operation of a processor. However, since a vapor chamber is required to deliver a large amount of heat, how to improve the structural strength of the vapor chamber in order to reduce the chance of thermal deformation and thus damage, is undoubtedly an important issue of the industry.
