摘　　要：针对工作时的PCS功率柜内部元件发热温度过高,提出了一种通过风道直吹发热器件的风扇导流结构。该解决方案在柜体内部搭建了一条从风扇直接达到发热器件的风道,通过合理调整风扇的风量和风速,直接将冷风通过风道吹向发热器件,以实现最佳散热效果。为了固定风道管道,还在箱体内部通过延伸支架来进行支撑。通过Icepak分析软件对所提出的风扇结构进行的热仿真分析表明其可以使功率柜内部发热器件温度明显降低,保证发热元件在工作中正常运行。In response to the issue of high temperatures of internal components in operation,a fan ducting structure that directs airflow directly onto the heat-generating devices is proposed.This solution builds a duct inside the cabinet that connects the fan directly to the heat-generating devices.By adjusting the air volume and velocity of the fan appropriately,the cold air is blown directly onto the heat-generating devices through the duct,ensuring optimal heat dissipation.To secure the ducting pipeline,support brackets are also used inside the enclosure.Thermal simulation analysis of the proposed fan structure conducted using Icepak software indicates that this solution can significantly reduce the temperature of the heat-generating devices inside the power cabinet and ensure the normal operation of capacitors and inductors.
