摘要
基于热传导微分方程、流体运动控制方程,建立了六相整流电路传热的数学模型,数值计算了水冷基板A、B、C3种不同结构下的管道流体的三维温度场和气流场。计算结果表明结构C温升及压力损失较小,综合散热效果最好。同时针对结构C进行了相关温升试验,数值计算结果和温升试验值较相吻合,符合工程设计需求。
Based on the heat conduction equation, fluid governing equation and radiation heat transfer equation, the mathematical model of the coupling heat transfer of the six-phase rectifier bridge heat sink was established. The three-dimensional temperature field and air flow field of pipeline fluid under A, B and C structures A , B and C of water-cooled substrates were calculated numerically. The calculation results show that the structure C temperature rise and pressure loss are small, and the comprehensive heat dissipation effect is the best. At the same time,the relevant temperature rise test was carried out for the structure C. The numerical calculation results are in good agreement with the temperature rise test values,which meets the engineering design requirements.
