Abstract
A cooling system for a variable frequency drive (VFD) of a transport refrigeration unit (TRU) is disclosed. The system comprises a conduit disposed within the vehicle and extending between a opening provided at a first predefined position on the outer body of the vehicle and the VFD being positioned at a second predefined position within the vehicle. The opening facilitates the inflow of ambient air within the conduit that carries the ambient air towards the VFD to enable cooling of the VFD. The system includes a grill cover adapted to be removably attached to the opening and/or the first end of the conduit, which allows entry of the ambient air within the conduit and restricts entry of outside objects and/or living organisms within the conduit.
