Optimal channel width distribution of single-phase microchannel heat sinks

摘要

The channel width distribution of single-phase microchannel heat sinks is optimized based on 1D-modeling. Two objectives are regarded, i.e. minimal thermal resistance and minimal wall temperature gradient. The results differ significantly from the present status in literature due to a new parameterization. In addition the effects of axial conduction, fin width and pressure drop are investigated.
