Abstract
A system for efficiently transferring heat from a cold sink to a hot source utilizing thermoelectric cooling effects is disclosed. A plurality of thermoelectric elements are coupled in a series configuration with a power source. The plurality of thermoelectric elements are coupled in a parallel configuration with the cold sink and the hot source. The surface area of the hot source is greater than the surface area of the cold sink such that the plurality of thermoelectric elements can effectively transfer heat from the cold sink to the hot source in response to the power source. The plurality of thermoelectric can be fabricated on an integrated circuit with analog or digital circuity and effectively cool hot spots.
