Thermo-Hydraulic Management System Employing Single-Phase Water Flow through Microchannels with Micro-Inserts Added Aiming for Performance Improvement

A microchannel heat exchanger effectively evacuates from a confined space. This paper attempts to gain insight into the combinatorial repercussions of simultaneously coupling two factors that affect microchannel’s performance, which channel size and micro-insert complexity are main contributors. With water as working fluid, an ANSYS-based numerical analysis was carried out for distinct sizes, 1 2 mm, both with without micro-inserts. The Reynolds numbers varied between 125 4992 250 9985 mm channels, respectively. For diameter channel, adding micro-inserts raised overall pressure drop increased number. inclusion in at first, thereafter decreased. Incorporating resulted enhanced transfer. trade-off transfer performance larger calculated by evaluating channel’s using thermal factor. Micro-inserts were found be most useful improving low-to-moderate number range, their effectiveness decreasing size. Changing structure design can improve transmission through microchannels.
