| Abstract: |
| The paper aims to study the effect of nitrogen pressure, nitrogen inlet flow rate and the depth of the heat sink channel on the heat transfer performance of the heat sink in the stainless steel-gas nitrogen heat plate heat sink. Ansys Fluent software was used to simulate the wall surface temperature distribution as well as inlet and outlet pressure loss of the plate heat sink. The temperature uniformity of heat sink could be improved by increasing nitrogen pressure and nitrogen inlet velocity, but the loss of heat sink inlet and outlet pressure would also increase. For gas-nitrogen plate heat sink, the change of channel depth had little effect on the uniformity of heat sink temperature, but when the channel depth was small, the pressure loss of inlet and outlet was large. It is suggested that when designing the gas-nitrogen plate heat sink, the flow channel depth should be selected from 8 mm to 10 mm; in the external process, the nitrogen pressure should be controlled between 0.3 MPa and 0.4 MPa, and the nitrogen flow rate should be controlled at 20 m/s. |
