AIR RETURN BULKHEAD FOR USE IN CONNECTION WITH A REFRIGERATION UNIT WITHIN A REFRIGERATION-TYPE CARGO TRAILER

摘要

A new and improved air return bulkhead for a refrigeration cargo traileris disclosed. The air return bulkhead comprises two primary components, afirstupper panel component and a second lower panel component. The first upperpanelcomponent effectively defines a fluid conduit through which relatively warmreturnair is fluidically conducted into the refrigeration unit, while the secondlowerpanel component comprises a structure upon which only a plurality of palletstopsare integrally formed. The second lower panel component is entirely separatefromthe upper panel component, and in this manner, whenever the pallet stopsbecomedamaged, only the used lower component needs to be simply detached andreplaced.An upper edge portion of the first upper panel component is also provided witha blade member which will engage the rear face of the refrigeration unit alonga linearlocus extending across the entire horizontal extent or width of therefrigerationunit so that cooled or refrigerated air cannot effectively be sucked back intothe inletor intake portion of the refrigeration unit, thereby preventing the occurrenceof"short cycling" of the refrigeration unit.
