RÉSUMÉ

AMCA flat tube is the key part of the condenser. This paper introduces a new type of microchannel heat sink (MHS) composed of a porous extruded aluminum flat tube in response to the increasing demand for heat transfer efficiency. In order to investigate the heat transfer characteristics of the heat sink, a mathematical model of three-dimensional conjugate heat transfer was first established. The availability of the submodel was obtained by the experimental and simulated contrast diagrams of the resistance coefficient and Nu number. Secondly, the effects of the height-to-width ratio of different channels and the number of channels on the heat transfer performance of the microchannel heat sink were studied. The thermal conductivity resistance, convective resistance, and heat capacity resistance of the three components of thermal resistance were calculated in detail. Furthermore, the flow resistance coefficient eventually increased in order to achieve an enhanced heat transfer. This study also provided a reference for the design of this type of heat sink.
