  • Portable computer with flexible heat spreader plate structure therein
    Patent number: 6075696
    Abstract: Operational heat generated by an electronic component in the base housing of a notebook computer is transferred to the back wall of its display housing for dissipation to ambient by a heat pipe disposed in the base housing and having an evaporator portion in thermal contact with the heat-generating component, and a spreader plate structure formed from multiple thin metal layers. The spreader plate structure has a heat dissipation portion disposed within the display housing and held in thermal contact with its back wall, a pickup region disposed in the base housing and held in thermal contact with a condensing portion of the heat pipe, and a bendable dynamic portion positioned between the heat dissipation and pickup portions and extending through the lid hinge area of the computer.
