An air return baffle for refrigeration trailers is characterized by a unitary panel molded from synthetic plastic material and containing integral baffles for improving air movement to the refrigeration unit of the trailer. The panel is adapted for mounting in sealed relation adjacent the front wall of the trailer and at least partially covers the refrigeration unit. 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, and the 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.

[ What is claimed is:] [1.] An air return bulkhead adapted for mounting adjacent a refrigeration unit in spaced relation from a front vertical wall of a refrigeration trailer, comprising(a) a generally rectangular panel including a front wall and side, top, and bottom walls extending normal to said front wall to define a cavity behind said front wall;(b) said panel front wall containing a plurality of openings in the lower portion thereof which enable air to enter said cavity; and(c) a plurality of normally closed vent means arranged in at least one of said walls and operable to allow air to enter said cavity when said openings are at least partially blocked, whereby air from the trailer isnormally drawn from the bottom and sides of the trailer and directed to the refrigeration unit by said panel to improve the overall cooling of the trailer and to eliminate hot and cold spots.
