Heat dissipation characterization of counterflow microchannels

This paper proposes two new counterflow microchannel structures - straight counterflow and serpentine counterflow, and performs thermal-flux coupling numerical simulation based on Fluent software to quantitatively characterize their surface temperature difference and heat transfer rate characteristics. By comparing and analyzing with traditional microchannel structures and fin air-cooled radiators, the significant advantages of the new structure in heat transfer uniformity and heat transfer efficiency are verified.
