Abstract:
A double heat exchange module for a portable computer, which is adapted to cool an integrated circuit within the portable computer, the double heat exchange module comprising:a thermally conductive structure, disposed within the portable computer and coupled with the integrated circuit, for conducting heat from the integrated circuit; a fan having a housing, said housing having an air inlet and an air outlet, said fan further having a fan blade disposed within said housing, said fan being disposed within the portable computer, said fan blade being rotatable to cause air to flow into said housing by way of the air inlet and out of said housing by way of the air outlet; and a heat exchanger, disposed on and outside said housing of the fan and being coupled with the thermal conductive structure, for double heat transfer, the heat exchanger comprising: an inflow portion, located on the air inlet of said housing, so that the air that flows into said housing by way of the air inlet, first passes through the inflow portion; and an outflow portion, located on the air outlet of said housing, so that the air that flows out of said housing by way of the air outlet, subsequently passes through the outflow portion.
