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.

[ What is claimed is:] [1.] A packaging interface between an electronic apparatus housing containing a thermal reservoir for storing heat that is produced at a locallized source within said housing and a Peltier effect control member having first and second hot junction electrical contacts and a cold junction portion, said Peltier effect control member being operable in response to power applied between said first and second contacts to become cold at said cold junction portion, comprising in combination:a thermal contact pad portion of said thermal reservoir positioned in an opening in said housing and essentially flush with the surface of said housing surrounding said opening,said cold junction portion of said Peltier effect device being positioned in an opening in a supporting member with said cold junction being flush with the surrounding surface of said supporting membersaid housing and said support member being in contact with each other and in registration whereby said contact pad and said cold junction are in contact,said support member being supported by an apparatus support member having an opening accommodating said Peltier effect device, and,force means urging said contact pad and said cold junction toward each other.
