摘　　要：针对光伏逆变器小型化、轻量化、高功率化发展带来的散热设计难题,设计了一种有效的强制风冷散热优化方案。首选,通过风量计算选定了合适风机;其次,使用代价函数对散热器质量和散热效果进行了双目标优化;最后,通过响应面优化得到了最优散热设计方案。结果表明:散热器温度和IGBT芯片结温均远低于标准要求,且保留裕量10℃以上。该结果为类似逆变器产品的散热优化设计提供了思路和参考。Aiming at the heat dissipation design problems brought about by the miniaturization,light weight and high power development of photovoltaic inverters,an effective forced air cooling optimization scheme is designed.Firstly,a suitable fan is selected through the calculation of air volume.Secondly,the cost function is used to optimize the radiator quality and heat dissipation effect.Finally,the opti⁃mal heat dissipation design scheme is obtained through the response surface optimization.The results show that both the heat sink tem⁃perature and the junction temperature of the IGBT chip are far lower than the standard requirements,and the reserve margin is more than 10℃.The research results provide ideas and references for the heat dissipation optimization design of similar inverter products.
