Air return bulkhead for refrigeration trailers

An improved air return baffle for refrigeration trailers (2) is characterized by a unitary panel molded from synthetic plastic material and containing integral baffles for improving air movement to the refrigeration unit (4) of the trailer. The panel is adapted for mounting in sealed relation adjacent the front wall (6) of the trailer (2) and at least partially covers the refrigeration unit (4). The lower portion of the panel contains a plurality of openings for drawing air into the cavity defined behind the panel. Air is directed by the baffles toward the refrigeration unit (4), and the improved air movement eliminates hot and cold spots within the trailer. Vents in the panel are operable should the openings become clogged and a strap is provided to removably connect the panel with the trailer wall. Wings on the upper wall of the panel direct air from the cavity to openings in the side portions of the refrigeration unit.
