Effects of shark bionic V-groove structures and nanofluids on thermal management of electronic components

Abstract

The miniaturization of electronic components makes it difficult for the traditional radiator working medium and radiator structure to meet the requirements. The combination of nanofluids and bionic micro-surfaces is beneficial to solve the heat dissipation problem of electronic components. Based on the bionics, a CPU enhanced heat dissipation system was designed and built based on the V-shaped groove of shark scales and Fe3O4-H2O nanofluids with high heat transfer coefficient. The effects of V-groove angle, height and nanofluids concentration on the comprehensive evaluation index of the radiator were studied. The groove angle S= 1 mm (54°) and height H= 2 mm have the best heat transfer characteristics and comprehensive evaluation index, which can reduce the surface temperature by 2.16 °C and 3.71 °C at most, and increase the heat transfer efficiency by 17.58% and 28.96%. There is a critical concentration (0.3%) that makes the system cooling effect best. The results of the study have a certain reference value for the structural design of heat sink
