| 摘 要： | 散热器的设计和散热分析是三相PWM变流器设计的关键技术.本文利用CFD软件ICEPAK分析了三相PWM变流器模块的散热性能,探讨了影响散热性能的各个因素.结果表明:散热器的换热系数随着风速的增大而增大,压力系数则越来越小.散热器的肋片数以及肋片厚度的增加导致流通面积变小,压力系数增大,换热系数逐渐增大.

| Abstract: | Design and thermal analysis of the heatsink is important technology in three-phase PWM converter design. The CFD software ICEPAK is used to analysis heat transfer characteristics of Three-Phase PWM converter module in this paper. In comparison with the hear- transfer as different fin count and different fin thick, five cases of fin count are investigated. The results indicateds that with the increase of inlet velocity, the heat coefficient of heatsink is increased and the pressure coefficient is decreased. With the increase of fin count and fin thick, the flow area is depressed and pressure coefficient is increased. |
