Abstract

A new and improved air return bulkhead for a refrigeration cargo trailer is disclosed. The air return bulkhead comprises two primary components, a first upper panel component and a second lower panel component. The first upper panel component effectively defines a fluid conduit through which relatively warm return air is fluidically conducted into the refrigeration unit, while the second lower panel component comprises a structure upon which only a plurality of pallet stops are integrally formed. The second lower panel component is entirely separate from the upper panel component, and in this manner, whenever the pallet stops become damaged, only the used lower component needs to be simply detached and replaced. An upper edge portion of the first upper panel component is also provided with a blade member which will engage the rear face of the refrigeration unit along a linear locus extending across the entire horizontal extent or width of the refrigeration unit so that cooled or refrigerated air cannot effectively be sucked back into the inlet or intake portion of the refrigeration unit, thereby preventing the occurrence of “short cycling” of the refrigeration unit.
