Title: HEAT EXCHANGE DEVICE FOR USE WITH UNDERWATER PRESSURIZED GAS SOURCE
Abstract:
A device for heat exchange for use with underwater diving equipment (100) including a pressurized gas source (102)is disclosed. The heat exchange device (200) includes a manifold (210) and a heat sink (220). The manifold distributes gas supplied from the pressurized gas source to breathing equipment(108). The heat sink is for warming up the gas before the gas is distributed to the breathing equipment using heat exchange with ambient water surrounding the heat sink. The manifold and the heat sink are connected such that the gas warmed up by the heat sink returns to the manifold before being distributed to the breathing equipment. The returning warm gas may warm up the manifold and the cold gas entering the manifold.
