More Information
Summary:The power conversion unit includes a housing, a plurality of fans, a heat sink, and a plurality of semiconductor elements. The fan generates a flow of air inside the housing. The heat sink forms an air flow path on the upstream side of the air flow path inside the housing. The plurality of semiconductor elements are arranged on the element arrangement surface of the heat sink in a direction intersecting the air flow direction at the heat sink. 电力转换单元具有框体、多个风扇、散热器以及多个半导体元件。风扇在框体的内部产生空气的流动。散热器在框体的内部的空气的流通路径的上游侧形成空气的流路。多个半导体元件在散热器的元件配置面沿与散热器处的空气的流通方向相交的方向排列配置。
