ABSTRACT:
The method of effecting an evacuated space above a quantity of vaporizable fluid contained in a conventional heat pipe. A quantity of vaporizable fluid 10 is admitted into the heat pipe 12 through an inlet assembly to displace residual air in the heat pipe for exhaust through vent 24. When the heat pipe is full of fluid, the inlet assembly including valve 16 and fitting 24 is removed and coupling 26 plugged. Pump 26 having a suction connection to the heat pipe is actuated, and fluid is withdrawn from the heat pipe through check valve 18 leaving an evacuated space to form above a predetermined quantity of vaporizable fluid. A cylindrical standpipe 38 above check valve 18 precludes the evacuation of vaporizable fluid from said heat pipe lower than the upper rim of said standpipe.
