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
