Micro Channel Heat Exchangers (MCHEs) have emerged as a critical component in automotive and commercial vehicle thermal management systems due to their enhanced heat transfer capabilities and space-efficient design. Constructed with numerous small-diameter, parallel microchannels, MCHEs maximize the surface area available for heat exchange, thereby enabling rapid and efficient thermal energy dissipation between working fluids. This structural efficiency allows for reduced system weight and volume, which is particularly advantageous in modern vehicle design where space and weight constraints are paramount. MCHEs are widely implemented in key vehicular subsystems, including air conditioning units, radiators, and charge air coolers, contributing to improved engine efficiency, lower fuel consumption, and reduced greenhouse gas emissions. Additionally, their inherent corrosion resistance and mechanical robustness ensure long-term reliability under harsh operational conditions, such as those encountered in heavy-duty and fleet vehicles, reinforcing their suitability for both light-duty and commercial transportation sectors.
