1. A vacuum booster pump comprising a modular heat exchanger for changing a temperature of a gas flow, the heat exchanger comprising:
at least one tube configured to contain a flow of fluid;
the at least one tube being at least partially embedded within a block of material, wherein the block is formed of a rigid, conductive material that holds and protects the at least one tube and conducts heat to the at least one tube;
at least one heatsink, wherein the heatsink is shaped extruded and finned and wherein the heatsink is separate from the block of material;
a thermally conductive material located between the heatsink and the block of material, the thermally conductive material is separate from the block of material and the heatsink, and wherein the heatsink is attached to the block of material and the thermally conductive material; and
mounting means configured to mount the heat exchanger adjacent to a gas port of a pump such that a least a portion of the heat exchanger extends into a path for gas flow flowing through the gas port,
wherein the mounting means comprises a flange, the flange being configured to connect with the gas port of the pump, the block being mounted to the flange such that the block extends towards at least one rotor of the pump when the flange is connected with the gas port of the pump.
