- Abstract
- The performance of microchannel PCHE (Printed Circuit Heat Exchanger) is superior to that of other existing commercial heat exchangers. Further, it is also more efficient than other heat exchangers. Various microchannels, whose shapes are straight (I), Wavy, Beehive, Surf, I-Wavy, I-Beehive, or I-Surf, are computationally modeled in this study. The counter-flow arrangement is used, and the flow characteristics, heat transfer, and pressure drop in the microchannels under various mass flow rate conditions are investigated. The results for I microchannel is chosen as the benchmarks and is compared with those of newly proposed microchannels. It is found that the surf-shaped microchannel is most efficient in improving the overall performance of a PCHE. © 2011 The Korean Society of Mechanical Engineers.
