An aftercooler housing (26) is made of lightweight sheet material which is assembled with an aftercooler core (44) so that the core (44) reinforces the housing. Housing (26) can be constructed from a sheet of suitable metal, plastic, fiberglass which extends around the core to provide an open ended configuration. End walls (36, 38) enclose the housing, and wall (36) supports both an air inlet port (24) as well as coolant fluid inlet and outlet ports (62, 64). Top wall (28) of the housing is tapered downwardly from wall (36) to wall (38) to provide a tapered air inlet chamber for the aftercooler. Reinforcing sections (58) are provided on the sidewall of the housing adjacent the engine, and cross tie members (72, 78) pass from the remaining sidewall of the housing through the housing to the reinforcing sections to transfer some of the load on the housing to the reinforcing sections.

An aftercooler assembly for an internal combustion engine designed to receive compressed charge air at or below a predetermined upper pressure limit for exchange with a fluid coolant comprising: (a) a housing defining an elongated chamber including: (1) a wrapper fabricated from sheet material and being incapable of resisting said upper pressure limit of charge air pressure by itself, said wrapper including opposed spaced side-walls, and (2) an end wall at each of opposite ends of said wrapper; (b) an elogated aftercooler core means positioned in said chamber for causing the engine charge air to flow in heat exchange relationship with the fluid coolant; and (c) a plurality of cross tie assemblies extending across the entire distance separating said first and second sidewalls and including spacer means of a length less than or equal to the width of the core means and (d) a cross tie securing means extending entirely through said housing, said spacer means and securing means cooperating in a manner drawing said first and second sidewalls into compressive engagement with said core means to form a unitized assembly capable of withstanding the upper limit of charge air pressure.
