A portable computer with a base (,) containing media, batteries, and keyboard, with the a CPU,and main PCB,located in a planar CPU module (,) separate from and behind the flat-panel display module (,), mechanically connected to the display module (,) with a deployment mechanism, and functionally connected to the display module (,) and base (,) by a base flexible circuit (,). The CPU module contains a heat-spreading front cover,facing the display module,, and thermally connected to hot components on the main PCB,The translating mechanism operates such that when the display module (,) is closed, the CPU module (,) is adjacent to the display module (,), and when the display module (,) is open, the CPU module (,) is positioned with a gap between the it and the display module (,).

Thermally efficient computer incorporating deploying CPU module

A portable computer is disclosed with a base, a display module containing a flat-panel display, a heat-spreader positioned to the rear of the display module, an insulating rear cover on the opposite side of the heat-spreader from the display module and serving at least in part as the rear outer surface of the portable computer for maintaining cool temperatures on the rear outer surface of the portable computer, and means for moving the heat-spreader and the insulating rear cover close to the display module when the portable computer is not being used, and for moving the heat-spreader and insulating rear cover a distance away from the display module when the portable computer is being used, and preventing touch access to the heat-spreader. Many structures are disclosed for the efficient cooling of the heat-spreader.

A method and apparatus is provided for monitoring and controlling the temperature at the heat producing portion of an electrical current carrying device without direct measurement at the heat producing site. An integrated circuit,is thermally attached to a plurality of heat dissipating paths; top side heat conduction path,, bottom side heat conduction path,, and board level heat conduction path,. On one of the heat conduction paths exists a heat flow sensor. This sensor is comprised of an inner thermistor,and an outer thermistor,. The measured heat flow is combined with a single point temperature measurement and the thermal conductivity between the heat source and the temperature measurement point to produce the temperature at the heat source. This temperature is monitored in order to keep the temperature of the electrical current carrying device below critical levels or within a specified range.

Method of junction temperature determination and control utilizing heat flow

A portable computer with a base (22) containing media, batteries, and keyboard, with the a CPU and motherboard located in a planar CPU module (28) separate from and behind the flat-panel display module (26), mechanically connected to the display module (26) with a deployment mechanism, and functionally connected to the display module (26) and base (22) by a base flexible circuit (78). The translating mechanism operates such that when the display module (26) is closed, the CPU module (28) is adjacent to the display module (26), and when the display module (26) is open, the CPU module (28) is positioned with a gap between the it and the display module (26).
