VAPOR CHAMBER WITH SUPERIOR HEAT TRANSPORT CHARACTERISTIC

摘要

PROBLEM TO BE SOLVED: To provide a vapor chamber with a superior heat transport characteristic, thanks to large transport amount of a working liquid.

SOLUTION: In the vapor chamber transporting heat by phase change between vaporization and condensation of the working liquid sealed in a container, a wick provided in an inner wall of the container is comprised of a porous sintered body having a frame formed by sintering metal powder around a pore, and silicon oxide is applied to the surface of the frame. The vapor chamber with the superior heat transport characteristic can be applied to cooling of a multiprocessor (MPU) or the like of a computer server, or application needing quietness in an apparatus wherein noise in using a fan for cooling becomes a problem such as a large liquid crystal or plasma display.
