Method for manufacturing planar thin heat pipe for cooling CPUs, involves pressing pipe thin by mechanical processing, completely adhering capillary structure at inner wall of pipe, evacuating pipe, filling pipe with fluid, and closing pipe

摘要

The method involves providing a pipe (2) and a net-like capillary structure (3). The structure is inserted into the pipe. An aid is provided and pushed into the structure. The pipe is sintered so that the structure is sintered at an inner wall of the pipe, and the aid is pulled out. The pipe is pressed thin by mechanical processing using a punching machine or a rolling machine, and the structure in the pipe is simultaneously pressed thin with the pipe. The structure is completely adhered at the inner wall. The pipe is evacuated, filled with working fluid, and closed.
