Temperature Uniformity in Cross-Flow Double-Layered Microchannel Heat Sinks

An in-house finite element method (FEM) procedure is used to carry out a numerical study on the thermal behavior of cross-flow double-layered microchannel heat sinks with an unequal number of microchannels in the two layers. The thermal performance is compared with those yielded by other more conven...
