Pump

A pump for a processor cooling system through which working fluid is circulated to cool a processor, the pump comprising:

• a processor heat exchanger;
• a casing configured to be coupled to the processor heat exchanger, the casing comprising an inlet for the working fluid and an outlet for the working fluid, the casing co-operating with the processor heat exchanger to define an internal pump cavity in which heat exchange can occur between the processor heat exchanger and the working fluid as the working fluid passes from the inlet to the outlet;
• a rotor mounted for rotation within the internal pump cavity, and
• a motor operable to rotate the rotor in order to drive the working fluid through the internal pump cavity from the inlet through the internal pump cavity to the outlet;
• wherein the pump is configured so that, in use, the processor heat exchanger lies adjacent, and abuts against, the processor so that heat can pass from the processor to the working fluid in the internal pump cavity as the working fluid is driven by the rotor from the inlet through the internal pump cavity towards the outlet.

A processor cooling system comprising a pump, and a heat exchange system fluidly coupled to the pump, the processor cooling system being arranged such that working fluid warmed by a processor is driven by the pump to and through the heat exchange system for heat transfer with an ambient environment, and thence from the heat exchange system back to the pump, wherein:

• said pump comprises:
• a processor heat exchanger;
• a casing configured to be coupled to the processor heat exchanger, the casing comprising an inlet for the working fluid and an outlet for the working fluid, the casing co-operating with the processor heat exchanger to define an internal pump cavity in which heat exchange can occur between the processor heat exchanger and the working fluid as the working fluid passes from the inlet to the outlet;
• a rotor mounted for rotation within the internal pump cavity, and
• a motor operable to rotate the rotor in order to drive the working fluid through the internal pump cavity from the inlet through the internal pump cavity to the outlet;
• wherein the pump is configured so that, in use, the processor heat exchanger lies adjacent, and abuts against, the processor so that heat can pass from the processor to the working fluid in the internal pump cavity as the working fluid is driven by the rotor from the inlet through the internal pump cavity towards the outlet;
• and said heat exchange system comprises:
• a heat transfer system, said heat transfer system comprising a fan, and a heat exchanger arranged relative to the fan so that the fan is operable to blow or draw air over and/or through the heat exchanger, wherein the fan and the heat exchanger each include a pathway through which the working fluid can flow, the respective pathways being coupled to one another so that the working fluid can flow through the fan and the heat exchanger to enable heat transfer between the working fluid and ambient air.

A computing resource comprising a processor, and a processor cooling system for cooling that processor, said processor cooling system comprising a pump, and a heat exchange system fluidly coupled to the pump, the computing resource being arranged such that working fluid warmed by said processor is driven by the pump to and through the heat exchange system for heat transfer with an ambient environment, and thence from the heat exchange system back to the pump, wherein:

• said pump comprises:
