Helping chips keep their cool
removes heat fluxes exceeding 250 W/cm at a thermal resistance below 0.15 C/W/cm Another design uses a MEMS (microelectromechanical systems) actuated microchannel, oscillating-flow heat spreader. A microactuator, integral to the heat spreader, generates and controls fluid oscillation. It also is made

across. Millimeter-sized channels are possible, but mixing and heat exchange advantages dissipate as the fluid path widens. The location of material flowing through the microchannel represents a time point in a reactions progress. Operators can therefore control the amount of heat pumped
