An apparatus to transfer heat from a heat source to a heat absorber, the apparatus consisting of an active thermal spreader plate with internal flow channels, a recirculating heat transfer fluid, and a means to impel the heat transfer fluid using an external moving magnetic field. In the most preferred embodiment a centripetal pump impeller is trapped inside the active thermal spreader plate, and the impeller is motivated to rotate due to eddy currents generated by the external moving magnetic fields.

[ The invention claimed is:] [32.] An apparatus for transferring heat from a heat producing component to the atmosphere, comprising:a) a composite substrate containing a closed interior channel for circulating a thermal transfer fluid, the composite substrate having a first and a second surface, the first surface for thermally contacting the heat producing component, and the second surface for thermally contacting the heat absorbing component, such that the thermal transfer fluid is in thermal contact with the first and second surfaces;b) a first rotatable electrically conductive non-magnetic fluid impeller contained in a portion of the closed interior channel, the first impeller being motivated to rotate by externally generated moving magnetic fields;c) a thermal transfer fluid contained within the closed interior channel;d) a first fin means contained within the composite substrate, the first fin means thermally contacting the first surface, the thermal fluid being in intimate contact with the first fin means;e) a second fin means external to the composite substrate and in thermal contact with the second surface, the atmosphere being in intimate contact with the second fin means;f) a second rotatable fluid impeller external to the composite substrate capable of impelling the atmosphere to flow passed the second fin means; andg) a motor means that rotates the second impeller, which impels the atmosphere to flow passed the second fin means, the motor means also producing externally generated moving magnetic fields, whereby the rotation of the first impeller by externally generated moving magnetic fields impels the thermal transfer fluid to circulate through the closed interior channel, so that heat is transferred from the heat producing component through the first surface through the first fin means into the thermal transfer fluid, and heat from the thermal transfer fluid is transferred through the second surface through the second fin means into the atmosphere.
