Overview

Numerical analysis evaluates convective heat transfer in microchannel heat exchangers, suggesting optimal configurations for enhanced cooling performance.

Key Points

The study aims to evaluate the cooling performance of microchannel heat exchangers using a MWCNT-water nanofluid under various geometries and channel counts.
Developed a 3D CFD model in ANSYS Fluent using the finite volume method.
Analyzed an aluminum MCHE with dimensions 45 mm × 45 mm × 7 mm.
Considered five channel geometries and three channel counts with two concentrations of MWCNT nanofluid.
Baseline configuration achieved a convective heat transfer coefficient of 2008.24 W/m²K.
Optimum configuration (curved sawtooth, 5 channels, 0.2% MWCNT) yielded h = 8271 W/m²K.
Channel geometry was identified as the most influential factor, contributing 70.6% to effectiveness.
