Abstract
An extended cooling unit ("ECU") for a portable PC is described. The ECU is connected to the portable PC having an MPP processor via a docking connector of the PC, thereby allowing the presence of the ECU to be detected by the processor. The ECU is connected to the portable PC via a docking connector of the PC, thereby allowing the presence of the ECU to be detected by the MPP processor of the PC. The ECU includes a horizontally projecting, thermally-conductive plate positioned such that, when the ECU is connected to the PC, the plate projects under the bottom of the PC to allow extension of a passive cooling solution. The ECU also includes a fan attached to a heat exchanger. Connection of the ECU to the PC results in a portion of the thermally conductive path of the ECU being brought into direct contact with the conductive path of the processor of the PC, thereby increasing the cooling capacity in the critical portion of the PC.
