Simulation on Heat Transfer Performance of Directionally Solidified Porous Copper Heat Sink

Article Preview

Abstract:

Porous copper fabricated by unidirectional solidification of metal-gas eutectic can be used to manufacture a special kind of micro-channel heat sink. A three dimensional model is developed to investigate the heat transfer in porous copper heat sink. However the experimental results of heat transfer performance are far less than the simulation results. That is mainly because some of the pores are nonpenetrative. When the simulation model is modified by taking the penetration ratio into account the experimental results are consistent with the simulation results.
