Patent ID: 8650755

Claim:
A method of making a length of a heat conduction pipe in a vacuum environment from a semi-finished heat conduction pipe filled with heat transfer medium by an equipment which includes: a housing having an enclosed space; an evacuation device provided outside the housing for evacuating the enclosed space into the vacuum environment; a squelching and cutting device provided in the enclosed space for squelching and cutting said semi-finished heat conduction pipe; and a brazing device provided in the enclosed space for brazing and sealing a cut end of said semi-finished heat conduction pipe; the method comprising: a material preparation step for preparing said semi-finished heat conduction pipe with a predetermined length sealed at both ends, a squelching and cutting step for squelching and cutting said semi-finished heat conduction pipe on a certain fixed point in the vacuum environment by the squelching and cutting device, and a sealing step for brazing and sealing the cut end of said semi-finished heat conduction pipe in the vacuum environment by the brazing device, wherein a plurality of semi-finished heat conduction pipes are processed at one time in the enclosed space.
