Thermal management of electronic components based on new wave bio-inspired structures and nanofluids

In recent years, due to the miniaturization of electronic components, nanofluids and bionics have attracted more and more attention in the field of heat exchanger heat dissipation. A heat exchange system for electronic components cooling based on Fe3O4-water nanofluids and wave bio-inspired structures was set up. The cooling effect and comprehensive performance of Fe3O4-water nanofluids in bio-inspired cooling system were experimentally investigated. The effects of nanofluids concentrations, angles and depths of wave bio-inspired structures and Reynolds numbers on the cooling system of electronic components were analyzed. The main novelty of this work lies in the design of a new bionic structure coupled with nanofluids cooling system for electronic components. It was found that large depth of the bio-inspired structure is advantageous for intensifying heat dissipation. There is a critical concentration (w = 0.3%) that allows the wave bio-inspired structure to have the best cooling effect. In the meantime, when the tilt angle is 65, the surface temperature can reach the lowest one. The performance assessment chart based on exergy efficiency was developed. It could be seen from the chart that all operating points were located in region 1 and region 2, which indicated that they all have good cooling performance.
