1. A compressor module, comprising:
an inlet and an outlet;
a working fluid flow duct between the compressor module inlet and the compressor module outlet;
a heat exchanger and a compressor rotor stage each in the working fluid flow duct, wherein the heat exchanger is in flow series between the compressor module inlet and the compressor rotor stage, and includes a wall having an external surface which is located in the working fluid flow duct, and wherein the compressor rotor stage is in flow series between the heat exchanger and the compressor module outlet; and
a heat sink unit which defines a portion of the working fluid flow duct in flow series between the compressor rotor stage and compressor module outlet;
wherein the heat exchanger is in heat transfer communication with the heat sink unit, such that the heat exchanger is operable to transfer heat to the heat sink unit from working fluid passing the heat exchanger;
wherein the heat sink unit defines a coolant flow passage for the transfer of a coolant;
wherein the heat sink unit defines a first inlet to the coolant flow passage, a second inlet to the coolant flow passage, and an outlet from the coolant flow passage, the first inlet to the coolant flow passage being spaced apart from the second inlet to the coolant flow passage along a length of the heat sink unit, and the outlet of the heat sink unit being between the first and second inlets to the coolant flow passage, such that coolant entering the first and second inlets to the coolant flow passage is exhausted via the outlet of the heat sink unit; and
wherein the first inlet to the coolant flow passage is configured to receive the coolant from a heat sink.
