A cooling system for a variable frequency drive (VFD) of a transport refrigeration unit (TRU) is disclosed. The system includes a conduit disposed within the vehicle and extending between an opening disposed at a first predetermined location on an outer body of the vehicle and a VFD positioned at a second predetermined location within the vehicle. The openings facilitate inflow of ambient air within the conduit that transports ambient air toward the VFD to effect cooling of the VFD. The system includes a grille cover adapted to be removably attached to the opening and/or the first end of the conduit that allows access of ambient air within the conduit and constrains access of external objects and/or living organisms within the conduit.

    公开一种用于运输制冷单元(TRU)的变频驱动器(VFD)的冷却系统。系统包括导管,其设置在车辆内,并且在设在车辆的外本体上的第一预定位置处的开口与定位在车辆内的第二预定位置处的VFD之间延伸。开口便于周围空气在导管内的流入,该导管将周围空气朝向VFD运送,以实现VFD的冷却。系统包括适合于可移除地附接于开口和/或导管的第一端部的格栅盖,其允许周围空气在导管内的进入并且约束外部物体和/或活生物体在导管内的进入。
