[ What is claimed is:] [1.] A fluid coupling assembly comprising;a housing having spaced side walls extending transversely to an axis and defining a fluid chamber,a shaft extending through and rotatably supported by one of said side walls,a disc supported by said shaft in said chamber in spaced relationship to said side walls,cooling fins for cooling said fluid chamber,said assembly characterized by a cooling sub-assembly comprising a ring extending axially as viewed in cross section, said cooling fins extending axially across said ring and generally radially of said ring, said cooling sub-assembly being secured to said housing for transmitting heat directly from said housing through said ring to said cooling fins. [11.] A fluid coupling assembly comprising; a housing having spaced side walls extending transversely to an axis and defining a fluid chamber, a shaft extending through and rotatably supported by one of said side walls, a disc supported by said shaft in said chamber in spaced relationship to said side walls, cooling fins for cooling said fluid chamber, a cooling sub-assembly comprising a support member supporting said cooling fins on said housing, said cooling sub-assembly being secured to said housing, said housing comprising stamped sheet metal components, said side walls having undulations therein, said undulations having an axial extent and said side walls having a thickness which is less than said axial extent of said undulations. An assembly as set forth in claim 11 wherein said disc includes undulations having an axial extent greater than the thickness of said disc. An assembly as set forth in claim 12 wherein said undulations of said disc are sandwiched between and axially overlap said undulations of said side walls.
