| Summary: | Aiming at an integrated module with high power, high heat flux gradient and non-uniform thermophysical conditions, heat transfer optimization design research was conducted based on uniform temperature technology. By using the research methods of numerical simulation and experimental testing, the initial no-heat-pipe scheme and the equal-temperature heat pipe scheme, including the forward and inverted mounting methods, were compared. The results show that: under the same wind speed, compared with the initial radiator without heat pipe solution, the temperature rise of the even-temperature heat pipe solution of the flip-chip method is reduced by 10.3~11.0 K, the maximum drop is 18%, and the temperature uniformity effect is increased by 32.5%; compared with the inverted method, the temperature rise of the uniform temperature heat pipe solution of the formal installation method can be further reduced by 6.9~9.4 K, with the maximum dropping 19.3%, and the uniform temperature effect is further increased by 83.6%, which is very significant. |
