ABSTRACT:
Heat transfer out of a housing for a locallized source of heat such as that produced by a semiconductor chip of electronic apparatus is provided by a low thermal impedance heat transfer member such as a heat pipe, a thermal reservoir or heat transfer buffering member and a Peltier effect device interfaced with the thermal reservoir and the ambient surrounding the housing so as to provide a refrigeration function for the thermal reservoir. A high heat capacity or high latent heat of phase transition material can be used for the thermal reservoir. In a portable computer with a battery power supply, the thermal reservoir can be independent or the battery can be employed in the thermal reservoir functions.
