Abstract
A device for heat exchange for use with underwater diving equipment including a pressurized gas source is disclosed. The heat exchange device includes a manifold and a heat sink. The manifold distributes gas supplied from the pressurized gas source to breathing equipment. 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.
Claims12
A heat exchange device for use with underwater diving equipment including a pressurized gas source, comprising:
- a manifold including a first chamber and a second chamber separated by a wall, the wall comprising a narrowing portion, each chamber including an inlet and an outlet for flow of gas into and out of each chamber;
- and
- a heat sink for heat exchange between the gas flowing in the heat sink and ambient water surrounding the heat sink, wherein the heat sink includes a passage for the gas to flow, wherein a first end of the passage is connected to the outlet of the first chamber, and wherein a second end of the passage is connected to the inlet of the second chamber.
