Abstract:
A cooling system for a portable computer which includes a computer body having a heat generating electronic element therein, and a display section having a screen connected in an openable manner to the computer body, the cooling system comprising:a cold plate assembly having a surface coupled to the heat generating electronic element for extraction of heat generated thereby; a heat exchange assembly disposed within the openable display section of the portable computer, the heat exchange assembly including a hollow channel for carrying coolant; a conduit for carrying coolant between the cold plate assembly and the hollow channel of the heat exchange assembly; a circulation pump for circulating coolant through the conduit between the cold plate assembly and the heat exchange assembly in a manner causing heat from the heat generating electronic element to be transferred to the coolant, and carried by the coolant to the heat exchange assembly for dissipation therefrom; and wherein the heat exchange assembly includes a thermally conductive plate and air-cooled fins, the hollow channel being coupled to the thermally conductive plate for facilitating the transfer of heat from coolant within the hollow channel to the thermally conductive plate, and the air-cooled fins being coupled to the thermally conductive plate for facilitating the dissipation of heat transferred to the thermally conductive plate from the coolant within the hollow channel.
