ABSTRACT:
Heat generating components in the base housing of a portable computer are thermally communicated with a longitudinal evaporator portion of a thermosyphoning heat pipe. A longitudinal condenser portion of the heat pipe is flattened, bent to a circular shape, and secured in thermal communication to the periphery of a metal housing base plate of an axial fan to form the shroud portion of the fan housing. With its axis vertically disposed, the fan is placed in a plenum area within the base housing beneath a cooling air inlet depression in the top base housing side which permits ambient air to flow into the fan even when the display housing portion of the computer is closed. Component operating heat is sequentially transferred into the heat pipe evaporating portion, along the heat pipe into its shroud-defining condenser portion and the metal housing base plate, into the air being flowed through the fan and along surfaces of the shroud and base plate, and is then discharged with the outlet air flowing through the plenum and outwardly through exterior wall openings in the base housing. Alternate centrifugal embodiments of the fan have housing air inlet and outlet air flow passage portions, and a scroll housing section, formed by a longitudinal condenser portion of a thermosyphoning heat pipe.
