Pump system for use in a heat exchange application

A pump system for use in a heat exchange application, comprising:

• a pump chamber, comprising a part of a heat exchange fluid circuit, having a fluid inlet and a fluid outlet;
• a heat source having a surface to be cooled, the surface to be cooled integrally connected with the pump chamber;
• and
• a rotating device, contained within the pump chamber, for causing a fluid to move across the surface to be cooled, resulting in a heat transfer between the surface and the fluid;
• where the pump chamber is separable from the surface to be cooled without disturbing the heat exchange fluid circuit.

A method of cooling a heat source having a surface that requires high heat transfer and minimal pumping power comprising the steps of:

• forming a pump chamber having a fluid inlet and a fluid outlet and a rotating device contained within the pump chamber for moving a fluid across the surface;
• coupling the surface of the heat source to the pump chamber so that the surface forms an integral part of the pump chamber;
• and
• passing the fluid through the pump chamber, where the fluid as it passes through the rotating device also passes across the surface, resulting in a heat transfer between the surface and the fluid.
