ABSTRACT:
A plunger placed through an opening in a heat pipe enclosure is heated to a temperature above the saturation temperature of the working fluid in the heat pipe to prevent the fluid from condensing across the gap between the plunger and the opening and to allow non-condensible gases to escape. Thereafter, the plunger is melted to seal the heat pipe. The plunger and at least that part of the heat pipe with the opening therethrough are made from the same materials.
