Abstract

An electronic apparatus heat extraction packaging feature wherein in the transfer of locally generated heat at a component of an electronic apparatus, the heat is stored in a buffering reservoir in the apparatus housing with a Peltier effect transfer control device being mounted external to the housing and interfaced with the thermal reservoir at the housing surface. The packaging interface permits the use of larger Peltier effect devices, greater freedom in precooling of the thermal reservoir and lighter weight portable computers where the Peltier effect devices are positioned in a docking station. 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.
