Abstract

A table carries guides for receiving and guiding a heat pipe. The heat pipe has a fill port which contains a valve. The heat pipe is thrust against the seal face of a block for evacuating and filling the fluid chamber of the heat pipe. A hex driver passes through the block and engages the valve to open and close the valve while the fill port is sealed from the atmosphere.
