摘　　要：本文针对三款电梯变频器风扇噪音问题,对每款变频器分别提出了两种降低风扇噪音的优化方案。经过风扇选型及热仿真计算,散热器温度控制在合理范围内,变频器匹配适合的风扇,从而使风扇总噪音降至最低。对比变频器温度测试数据与热仿真数据,得出热仿真结果的误差在5%以内的结论。温度测试数据证明了热仿真的准确性,也证明了噪音优化方案的准确性。本文提出的风扇噪音优化方法可为降低电梯变频器风扇噪音提供参考。This article focuses on the fan noise problem of three elevator inverter,two optimization schemes for reducing fan noise have been proposed for each inverter.After fan selection and thermal simulation,the temperature of heat sink is controlled within a reasonable range,and the inverter matches the suitable fan,so that the total noise of the fan is reduced to the minimum.By comparing the temperature test data with the thermal simulation data,the error of the thermal simulation results is less than 5%.The temperature test data prove the accuracy of thermal simulation and noise optimization scheme.The fan noise optimization method proposed in this paper can provide reference for reducing the fan noiseofelevatorinverter.
