Abstract:
For use in cooling an electronic component, an integrated cooling device, comprising:a heat sink having a plate couplable to and supportable by said electronic component, said plate having at least one channel therein that presents an enhanced surface area; a sealed and substantially U-shaped heat pipe having a heat-receiving portion fitted within said at least one channel to cause said enhanced surface area to contact said heat pipe to increase thermal communication between said plate and said heat pipe, said heat pipe further having a heat-removing portion distal from said heat receiving portion; a cooling fan coupled to and supported by said heat sink and interposed between said heat receiving portion and said heat-removing portion of said heat pipe; and a fluid, initially located in said heat-receiving portion as a liquid, configured to receive heat via said enhanced surface area, evaporate to form a vapor, travel to said heat-removing portion, condense in said heat-removing portion and cycle back to said heat-receiving portion.
