Abstract:
1. A method of fabricating an apparatus comprising: providing a portable computer; providing a docking station; said portable computer comprises a low performance CPU comprising said low performance mode of operation and a high performance CPU comprising said high performance mode of operation; providing a sensor for sensing if said portable computer is engaged in said docking station or if said portable computer is not engaged in said docking station; both said high and said low performance modes of operation are actively user usable modes of operation; providing a signal generator for switching said computer between said high performance mode of operation and said low performance mode of operation in response to an input; said input being selected from the group consisting of providing an output of said sensor indicating that said portable computer is engaged with said docking station and for switching said portable computer into said high performance mode of operation, and an output of a temperature sensor which monitors the operating temperature of said computer to switch said computer between said high performance mode of operation and said low performance mode of operation; said portable computer comprises a low performance CPU comprising said low performance mode of operation and a high performance CPU comprising said high performance mode of operation; providing said portable computer with a portable computer cooling system; providing a releasable clamp for providing physical and thermal engagement between said portable computer and said docking station, said releasable clamp releasably physically and thermally coupling to a heat spreader, which is in thermal contact with a heat generating source in said portable computer said heat conduction member thermally coupled to a heat sink in said docking station through a thermoelectric cooler, said heat sink in said docking station is thermally coupled to a second air blower in said docking station for causing airflow over said heat sink in said docking station, said releasable clamp permits said engaged cooling system to provide a higher heat dissipation capacity to said portable computer when operating in said high performance mode of operation from said high performance CPU than the maximum heat dissipation capacity provided by said first air blower to said portable computer when operating in said low performance mode of operation from said low performance CPU; cooling the combination of said engaged said portable computer and said docking station with the combination of said portable computer cooling station system and a docking station cooling system providing enhanced cooling of said portable computer when engaged with said docking station and operating in said high performance mode of operation and for reduced cooling of said portable computer when disengaged from said docking station and operating in said low performance mode of operation; a first heat pipe and a second heat pipe each having a first end, embedding said first at a first end of a heat spreader, placing each of said said first end of said first heat pipe and said first end of said second heat pipe substantially in parallel with a first groove and a second groove in said heat spreader, housing said heat spreader in said portable computer, disposing said first groove and said second groove in said heat spreader in a portion of said heat spreader for engagement with a clamp mechanism of said docking station, forcing said heat spreader in between a first rotor and a second rotor of said clamp mechanism, each of said first rotor and said second rotor are formed of a thermally conductive material, in said engaged cooling system said first rotor is inserted in said first groove and said second rotor is engaged in said second groove, providing a heat sink in said docking station, providing a third heat pipe and a fourth heat pipe which are used to carry the heat received from said first rotor and said second rotor to a heat sink in said docking station, thermally connecting said heat sink in said docking station from said first rotor and said second rotor to said heat sink in said docking station, supporting said first rotor by a first support for said first rotor and by a second support for said first rotor, supporting said second rotor by a first support for said second rotor and by a second support for said second rotor, said first rotor is free to rotate along a first axis defined by said first support for said first rotor and by said second support for said first rotor, said second rotor is free to rotate about a second axis defined by said first support for said second rotor and by said second support for said second rotor, disposing a first end of said third heat pipe is inside said first rotor and disposing a first end of said second rotor inside of said second rotor, providing said first rotor and said second rotor with thermal and lubrication grease to improve heat transfer from said first rotor to said third heat pipe and from said second rotor to said fourth heat pipe and to reduce friction of said first rotor about said first axis and said second rotor about said second axis, supporting said first support for said first rotor by a first holder for said first support for said first rotor and supporting said second support for said first rotor by a second holder for said first support for said first rotor, supporting said first support for said second rotor by a first holder for said first support for said second rotor, and supporting said second support for said second rotor by a second holder for said first support for said second rotor, mounting said first holder for said first support for said first rotor and mounting said second holder for said second support for said first rotor on one side of a bottom plate of said heat sink in said docking station at a common anchor point which are free to rotate about a common anchor point by a rotation angle constrained by a first stopper and providing a first spring for said first holder for said first support for said first rotor and by providing a second stopper and a second spring for said first holder for said first support for said second rotor, said first stopper acting with said first spring and said second stopper acting with said second spring providing a clamping force between said first rotor and said second rotor fixedly docking said portable computer to said docking station and providing thermal interconnection there between when said end of said heat spreader is inserted between said first rotor and said second rotor to dispose said first rotor in said first groove in said heat spreader and to dispose said second rotor in said second groove in said heat spreader to extract heat from said portable computer to said heat sink in said docking station, and providing an air blower in said docking station for extracting heat from heat sink in said docking station; thereby providing capacity to said portable computer when operating in said high performance mode of operation from said high performance CPU greater than the maximum heat dissipation capacity provided by said first air blower to said portable computer when operating in said low performance mode of operation from said low performance CPU.
