The role of hydro-ecological models in the development of sustainable water resources

A device that efficiently transfers heat from a heat source. The device includes a heat sink, the heat sink comprising a thermally conductive base, and a plurality of thermally conductive pin fins coupled to the thermally conductive base. A gas source, such as a blower, proximate to the pin fins, directs a gas, such as ambient air, axially along at least a portion of the pin fins, and then in a direction radial to the pin fins and substantially parallel to the heat source, to transfer heat away from the heat source. The heat transfer device may be utilized in any application that requires efficient removal of heat from a heat source, for example, an electronic device such as an integrated circuit or microprocessor.
