A heat exchanger is disclosed for cooling a gas from a first temperature to a second temperature. The exchanger comprises a first heat exchanging chamber, a second heat exchanging chamber and an array of heat pipes which are arranged to extend from within the first heat exchanging chamber to within the second heat exchanging chamber. The first heat exchanging chamber comprises an inlet for receiving a coolant into the chamber and an outlet through which the coolant can exit the first chamber, the coolant being arranged to pass over the portion of the heat pipes which extend within the first chamber. The second heat exchanging chamber comprises an inlet for receiving the gas at a first temperature into the chamber and an outlet through which the gas can exit the second chamber at a second temperature. The gas is arranged to pass along the second chamber between the inlet and the outlet, along a path comprising a substantially constant cross-sectional area to minimize the pressure drop between the inlet and the outlet.
