A LIQUID COOLED VARIABLE CHANNEL WIDTH DOUBLE LAYERED MINICHANNEL HEAT SINK (VWC DL-MCHS) WITH ZERO OVERLAP

摘要

ABSTRACT A Liquid Cooled Variable Channel Width Double Layered Minichannel Heat Sink (VWC DL-MCHS) with zero overlap consists of a substrate and two layers of MCHS having variable width of the channels in axial direction. In VWC DL-MCHS, the denser channels (closely spaced fins) are provided at the downstream section (after the stepped location) and coarser channels are provided at the upstream section (before the stepped location). Two layers of VWC DL-MCHS are kept in the counter flow direction in such a way that the denser channel regions of upper and lower layers do not overlap (Zero Overlap). The coolant passes through each layer simultaneously and dissipates the heat from high heat generating microelectronic system. The present invention of VWC DL-MCHS with zero overlap provides highly compact, more efficient and cost effective solution to the thermal management of microelectronic devices.
