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.

A scrubber-heating apparatus for a diving rebreather includes an oxygen supplying element. The oxygen supplying element has a gas mixing portion connected thereto. The gas mixing portion has a breath connecting element connected thereto. The breath connecting element has a scrubber connected thereto. The scrubber is provided with an absorbent heating element and a temperature detecting component. The temperature detecting component has a state display connected thereto. The absorbent heating element and the state display are electrically connected to a power supplying portion. Thereby, the scrubber can recycle gas exhaled by a user to prolong the duration of use of the rebreather. Additionally, the absorbent heating element increases the temperature in the scrubber, thereby enhancing the adsorption efficiency and prolonging the overall duration of use.
