Method and equipment of making a length of heat conduction pipe in a vacuum environment from a semi-finished heat conduction pipe

摘要

A method of making a length of heat conduction pipe from a long conduction pipe filled with heat transfer medium in vacuum environment comprises: a material preparation step in which a long heat conduction pipe with predetermined length sealed at both ends is prepared, a squelching and cutting step in which squelching and cutting is conducted on pre-determined point of said long heat conduction pipe in vacuum environment; a sealing step by which the cut end of said long heat conduction pipe is brazed and sealed in vacuum. There also provides an equipment for performing the method.
