Abstract
The thermal performance of single layer counter-flow (SLCF) microchannel heat sinks with two-phase flow have been analyzed using the finite element method. Parameters such as the thermal resistance, pressure drop and the temperature distribution in SLCF heat sinks with two-phase flow have been determined and compared with those for the single layer parallel flow (SLPF) heat sinks with two-phase flow. It is observed that two-phase flow in the micro-channel heat sinks generally yield low thermal resistance and better temperature uniformity in the stream-wise direction. It is also observed that the thermal performance of the SLCF microchannel heat sinks are better especially at higher base heat fluxes compared to the SLPF heat sinks working under similar conditions
