<p>A pump and heat exchanger for pumping an electrically conductive fluid by interaction with a magnetic field and a flowing second electrically conductive fluid wherein a plurality of tubes (38, 40) are arranged within a circular annulus formed between concentric shells (30, 32). One of the fluids is pumped by conventional means (18) through the radial spaces between the tubes (38, 40), generating currents and voltages which cause the other fluid to flow within the tubes (38, 40) and in the opposite direction. In magnetic air gap regions (44, 46) 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 while the fluid is propelled through the tubes (38, 40) without a mechanical drive pump.</p> |
