Abstract
Optimizing heat exchangers is a crucial engineering challenge in industrial processes and energy production. Microchannel heat exchangers have been developed to increase thermal efficiency in cooling systems, allowing for better heat dissipation in a reduced space. However, optimizing these heat exchangers can be complex due to the large number of variables involved in the process. Genetic Algorithms (GA) are one approach to optimizing microchannel heat exchangers, based on the concept of natural selection and biological evolution, and capable of finding optimal solutions to complex problems through selection and reproduction processes. In this study, the thickness of the base (Hbase), top (Htop) and channels walls (Wwall), and channel width (Wchannel) and height (Hchannel) were optimized for constant flowrate and heat flux. The minimization of the pressure drop (
