Abstract
A pump and heat exchanger for pumping a conductive fluid through interaction with a magnetic field and a flowing second conductive fluid. A plurality of tube sets are arranged along radii of a circular annulus formed between two shells. One of the fluids is pumped by conventional means through the radial spaces between the tubes, generating currents and voltages which cause the other fluid to flow within the tubes and in the opposite direction. In magnetic air gap regions of the pump, the tubes are rectangular in shape. As a result of the circular geometry, currents flow circumferentially within the annulus, and voltages are maintained at a low value.
