Abstract

Abstract An air return bulkhead is provided for mounting on the interior surface of one upstanding wall of a container, the container wall supporting an airflow heat exchanger assembly on an upper portion thereof including a central downwardly opening air inlet, a pair of upper opposite side horizontally and oppositely outwardly opening air inlets and a central upper temperature conditioned air outlet. The bulkhead is constructed to define an upstanding return airflow path extending upwardly along the one wall with the airflow path including a central portion and a pair of opposite side portions. The upper end of the central portion of the airflow path is registered with the central downwardly opening air inlet and the upper ends of the opposite side portions of the flow path are disposed outwardly of the opposite sides of the airflow heat exchanger. A pair of opposite side upper extensions are provided for the bulkhead and mounted on the latter in adjusted upward extended positions relative thereto. The extension define open ended horizontal flow paths above the upper marginal edge of the bulkhead upwardly into which the upper ends of the opposite side portions of the upstanding return airflow path open. The remote ends of the horizontal flow paths open horizontally outwardly along the one wall and the adjacent ends of the horizontal flow paths are registered with the opposite side air inlets of the airflow heat exchanger assembly.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 298 words
In combination with a container for storage and shipment of temperature controlled materials and wherein said container includes an airflow heat exchanger assembly mounted on a upper portion of one wall of said container and said heat exchanger assembly includes a central downwardly opening air inlet, a pair of upper opposite side horizontally and oppositely outwardly opening side air inlets and a central upper temperature conditioned air outlet, an air return bulkhead including upstanding opposite side marginal edges and top and bottom marginal edges and mounted on said one wall defining, in conjunction with said one wall, an upstanding return airflow path between said one wall and said bulkhead bounded by said side marginal edges and including a central portion and opposite side wall portions, the central portion of the upper end of said return airflow path being registered with said central downwardly opening air inlet, upper opposite side extensions for said bulkhead vertically adjustable relative thereto and defining open ended horizontal flow paths above said top marginal edge and into which the opposite side portions of said upper end of said air return flow path open, the remote ends of said horizontal flow paths opening outwardly along said one wall and the adjacent ends of said horizontal flows paths being registered with said side air inlets, a plurality of vertically spaced horizontal mounting bars secured to said front wall, said bulkhead including vertically extending laterally spaced corrugations formed in at least the lower portion thereof with portions of said corrugations abutted against said one wall, said portions of said corrugations including a plurality of vertically spaced sets of horizontally spaced and aligned notches formed therein in which longitudinally spaced portions of said bars are received, the notched portions of said corrugations being removably secured to said bars.
Claim 2
Dependent Claim 298 words
In combination with a container for storage and shipment of temperature controlled materials and wherein said container includes an airflow heat exchanger assembly mounted on a upper portion of one wall of said container and said heat exchanger assembly includes a central downwardly opening air inlet, a pair of upper opposite side horizontally and oppositely outwardly opening side air inlets and a central upper temperature conditioned air outlet, an air return bulkhead including upstanding opposite side marginal edges and top and bottom marginal edges and mounted on said one wall defining, in conjunction with said one wall, an upstanding return airflow path between said one wall and said bulkhead bounded by said side marginal edges and including a central portion and opposite side wall portions, the central portion of the upper end of said return airflow path being registered with said central downwardly opening air inlet, upper opposite side extensions for said bulkhead vertically adjustable relative thereto and defining open ended horizontal flow paths above said top marginal edge and into which the opposite side portions of said upper end of said air return flow path open, the remote ends of said horizontal flow paths opening outwardly along said one wall and the adjacent ends of said horizontal flows paths being registered with said side air inlets, a plurality of vertically spaced horizontal mounting bars secured to said front wall, said bulkhead including vertically extending laterally spaced corrugations formed in at least the lower portion thereof with portions of said corrugations abutted against said one wall, said portions of said corrugations including a plurality of vertically spaced sets of horizontally spaced and aligned notches formed therein in which longitudinally spaced portions of said bars are received, the notched portions of said corrugations being removably secured to said bars.
Claim 3
Dependent Claim 21 words
The combination of claim 1 wherein said container is elongated and said one wall comprises an end wall of said container.
Claim 4
Dependent Claim 29 words
The combination of claim 2 wherein said container comprises an insulated load body mounted on a trailer chassis, said one wall comprising the forward wall of said load body.
