A unit core radiator is provided with support for the top tank and bottom tank so as to prevent the top and bottom tanks from vibrating relative to the support and at the same time to permit expansion and contraction of the core relative to the support. Mating members are carried by the top tank and the side channels and are urged against each other to form slip joints to allow limited movement between the tank top and the side channels in adjusting for temperature changes in the cooling fluid.

Floating radiator tank top

A heat exchange structure is provided wherein a radiator (10) has a cooling core (24) extending between a top tank (22) and a bottom tank (20) with the bottom tank (20) being open (38) at one side. A cooler (66) for cooling a second fluid is mounted on a plate (46) which is sealingly secured over the open side (38) of the bottom tank (20) to position the cooler (66) in said bottom tank (20). A baffle (55) is mounted in the bottom tank (20) to divert fluid flowing through the cooling core (24) past the cooler (66). The plate (46) with the cooler (66) attached is removable from the bottom tank (20) without disturbing the connections between the cooling core (24) and the bottom tank (20). The heat exchange structure is assembled in a picture frame mounting (12) with attaching members (16) passing through bottom members (17) of the picture frame mounting (12) and threading into fasteners (18) in the bottom tank (20) to removably anchor the picture frame mounting (12) and the heat exchange structure together.

Heat exchange structure

A receptacle is provided to receive and reinforce an engine fluid cooling radiator core. The core is secured within the receptacle and mounted adjacent an implement fluid cooling core. The implement cooling core and the receptacle are connected by at least one, but preferably two connector bars. The connector bars are resiliently connected to an associated supportive frame.
