چکیده
In this work\ a new concept for a two!layered micro!channel heat sink with counter current ~ow arrangement for cooling of the electronic components is proposed[ The thermal performance and the temperature distribution for these types of micro channels were analyzed and a procedure for optimizing the geometrical design parameters is presented[ While the power supply system of the two!layered design is not signi_cantly more complicated than the one!layered design\ the streamwise temperature rise on the base surface was found to be substantially reduced compared to that of the one!layered heat sink[ At the same time\ the pressure drop required for the two!layered heat sink was found to be substantially smaller than that of the one!layered heat sink[ The results demonstrate that the two!layered micro!channel heat sink design is a substantial improvement over the conventional one!layered micro!channel heat sink[ Þ 0888 Elsevier Science Ltd[ All rights reserved[

Effect of Using Nano Encapsulated Phase Change Material on Thermal Performance of Micro Heat Sink
The aim of this paper is to enhance thermal performance of a microchannel heat sink by using nanoencapsulated phase change material (NEPCM) slurry as a cooling fluid instead of pure fluid. A threedimensional model of a circular channel using water slurry of NEPCM was developed. The results show a significant reduction in the mean fluid temperature along the channel and heat sink wall temperatu...

This paper explores several issues important to the thermal design of single-phase and two-phase micro-channel heat sinks. The first part of the paper concerns single-phase heat transfer in rectangular micro-channels. Experimental results are compared with predictions based on both numerical as well as fin analysis models. While the best agreement between predictions and experimental results wa...
