Abstract: A refrigerated cargo vehicle has components therein effective to uniformly distribute cooling air throughout a cargo body which is divided into a plurality of compartments including a center compartment by a plurality of longitudinally spaced partitions extending transversely between opposite side walls of the cargo body. Laterally spaced walls extend longitudinally from each end wall of the cargo body and terminate at the respective partitions defining the center compartment thereby defining upwardly opening passages each communicating with respective opposite end portions of a duct extending between and through the partitions defining the center compartment.
