摘要
对矿用变频器主电路器件损耗做了全面分析,用线性近似法对IGBT进行损耗分析,分析了功率器件内部热源与外界环境之间的热流路径,并在此基础上设计出了水冷散热器。实验表明,该散热设计使变频器具有很好的散热效果,可满足工业实际应用的要求。
This paper puts forward an accurate calculation method for the power devices that is used in the mid-voltage & high-power inverter.Heat path between the heat source of power device and external environment are analyzed in this paper,and a water cooling radiator is designed based on the calculation and analysis.The results of the experiment show that inverter have a good heat dissipation effect with the radiator,and can satisfy the demand in industrial application.
