摘要

针对某大功率、高热流密度梯度、非均匀热物理条件的集成模块，基于均温技术进行传热优化设计研究，应用数值仿真和试验测试的研究方法，将初始无热管方案、倒装方式均温热管方案和正装方式均温热管方案进行对比。结果表明，在相同的风速工况下，倒装方式的均温热管方案相对初始无热管方案散热器温升减小10.3~11.0 K，最大降幅达18%，均温效果最大提升32.5%；相对于倒装方式的均温热管方案，正装方式均温热管方案在温升方面可进一步减小6.9~9.4 K，最大降幅达19.3%，均温效果进一步提升83.6%，传热效率非常显著。

Abstract

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.
