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.
In a heat exchange structure comprising a radiator (10) having a downstream tank (20), means for admitting heated fluid to the radiator (10) wherein said fluid flows through the radiator (10) to the downstream tank (20), said downstream tank (20) has an opening (38) in one side thereof, baffle means (55) mounted in said downstream tank (20) for diverting flow from the radiator through said baffle means (55), and oil cooler (66) mounted in said downstream tank (20) in close association with said baffle means (55) whereby said flow through said baffle means (55) flows over said oil cooler (66), a plate (46) sealingly attached over said opening (38) in said downstream tank (20), and an outlet (52) in said downstream tank (20) downstream from said baffle means (55) and oil cooler (66) for exiting the fluid from said downstream tank (20).
In a heat exchange structure comprising a radiator (10) having a top tank (22), a bottom tank (20) and a bundle of tubes (24) extending between said top tank (22) and bottom tank (20), means for admitting heated fluid to the top tank (22) wherein said fluid flows through the top tank (22) and through the tubes (24) to the bottom tank (20), the bottom of said bottom tank (20) being open (38), a baffle means (55) mounted in said bottom tank (20) for diverting flow from said tubes (24) through said baffle means (55), a bottom plate (46) covering said open bottom (38) of the bottom tank (20), an oil cooler (66) mounted on said bottom plate (46) and projecting into said bottom tank (20) in line with said baffle means (55) whereby said flow through said baffle means (55) flows over said oil cooler (66), an oil inlet (70) and an oil outlet (71) passing through said plate (46) into and out of said oil cooler (66), means (50) for sealingly attaching said plate (46) to said bottom tank (20) to seal said bottom tank (20) closed, and an outlet (52) in said bottom plate (46) downstream from said baffle means (55) and oil cooler (66) for exiting the fluid from said bottom tank.
