Abstract
A braze furnace of the inert gas type cooperatively uses the waste heat from the cooling chamber to vaporize liquid inert gas, while using the coolness of the inert gas being vaporized to accelerate the cooling process itself. The walls of the cooling chamber provide a hollow plenum into which stored liquified inert gas is metered and vaporized. From the plenum, vaporized gas is routed wherever needed to purge oxygen from the system. In addition, liquid gas can be injected directly into the cooling chamber for even quicker, direct part cooling and the purge the cooling chamber.
