摘要
针对某工程对绝缘栅双极型晶体管(IGBT)散热器的使用要求,提出一种螺旋流道结构形式的水冷散热器。根据传热学和流体流动基本理论,并通过正交试验法优化设计散热器的流道结构,利用数值模拟的方法仿真分析散热器的性能,根据仿真结果和使用需求确定最优设计方案。通过样机试制及样机热阻、流阻性能试验测试,对比分析数值模拟与试验测试的结果,证明了数值模拟的准确性,解决了工程中IGBT的散热问题。
Aiming at the requirement for insulated gate bipolar transistor （IGBT） radiator used in some electric power project of state grid,a spiral flow channel water-cooling IGBT radiator is designed.According to the basic theory of heat transfer and fluid dynamics,the flow channel is optimized by orthogonal design.And then the performance of the radiator is analyzed with numerical simulation which based on the optimum design proposal is determined.The sam- pies for the optimum design proposal is manufactured and the radiator＇s performance is tested.Compared the test re- suits with the simulation data, the numerical simulation is reliable for designing IGBT radiator and the heat dissipation problems for IGBT in projects are sovled.
