Abstract
An apparatus for cooling an electrical heat source is disclosed. A heat exchanger has two principal sub-assemblies. A closed-loop fluid flow is provided through a second sub-assembly, disposed next to a heat source. An open-loop fluid flow is provided though a first sub-assembly in communication with a second sub-assembly. Each of the first and second sub-assemblies has a rotational element. The fluid flow entering the first sub-assembly rotates the first rotational element, and magnetic communication between the rotational elements causes movement of the second rotational element, thereby achieving fluid movement within the second sub-assembly. Operationally, the closed-loop sub-assembly removes heat from the heat source and transfers it to the open-loop sub-assembly for subsequent heat transfer in a downstream fluid flow.
