Abstract
Effective utilization of a parallel flow air-cooled microchannel array at the micro electro mechanical systems (MEMS) scale is prohibited by unfavorable flow patterns in simple rectangular arrays. The primary problem encountered is the inability of the flow stream to penetrate a sufficient depth into the fin core to achieve the desired fin efficiency. Embodiments of the present invention overcome this problem using a manifold with open nozzle discharge and integrated lateral exhaust along with a microchannel array cooler with micro spreading cavities for internal air distribution.
