The role of microchannel geometry selection on heat transfer enhancement in heat sinks: A review

Dash, Binayak, Nanda, Jajneswar, Rout, Sachindra Kumar·2022·Heat Transfer

Abstract

Extensive research has been carried out by researchers for improving the thermal efficiency of the microchannel. There are various types of methodologies that have been proposed by authors for different geometry and fluid flow. The use of microchannel in the miniature heat exchangers and microchannel heat sink (MCHS) have taken the science of heat transfer to an another level for which the field of electronic device cooling, aerospace applications, automobile sectors, biomedical engineering, and chemical engineering sectors are being keen toward further development of the technology. Since 3 decades, the microchannel has been tested numerically, experimentally, and analytically for establishing the theories of hydraulic and thermal efficiency during fluid flow. Improper geometry selection of microchannel may lead to carry various losses such as pressure drop, friction factor, wall shear stress, and temperature jump. Available investigations and results have been reviewed immensely in this paper to give a clear prospective for further research in selecting a proper channel geometry.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Compared with conventional fin-and-tube heat exchangers, microchannel heat exchangers have higher heat transfer efficiency, less refrigerant charging, and lower cost.

    “Compared with the conventional fin-and-tube heat exchanger (FTHX), the MCHX has the advantages of higher heat transfer efficiency [1,2], less refrigerant charging [3], and lower cost [4,5].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
