A Comprehensive Review on Microchannel Cooling Application for Automobile Air Conditioner System

Microchannels made of MEMS have garnered attention in microfluidics and biological disciplines for over 40 years. The literature lacks a complete examination of their design, type, and applications, despite their diverse applications. This review will provide specific knowledge for those studying microchannels. Microdevices are in high demand, especially in industrial applications, because of their enhanced characteristics, versatility, and tiny size. The primary objective of this study is to categorize and use microchannels. Several examples of these techniques include molding, electroplating, lithography, lab-on-chip, micro-molding, micromachining, micro-milling, laser ablation, hot embossing, EMM, and etching. Furthermore, a considerable number of hybrid microchannel manufacturing techniques have been identified. Overall, this analysis highlights developments in microchannel manufacturing. The paper provides a qualitative examination of microchannel design, geometry, and heat transfer prediction. Microchannels are fabricated using a variety of materials, including silicon, polymers, ceramics, and metals, which are selected based on their specific use. Silicon, glass, and polymeric materials are employed on metallic substrates. This research introduces methodologies for the identification of the most optimal microchannel and provides suggestions for potential future advancements.
