A combination structure interconnecting and sealing means for joining an air duct with the end plate of a heat exchanger core to allow for variations in spatial dimensions resulting from thermal expansion. The coupling arrangement comprises a circumferential flange attached, as by welding, to the circular duct. The periphery of the flange is provided with radial slots which are engaged underneath T-shaped clips attached to the heat exchanger plate. Within the circumference of the flange and generally in line with the duct and associated manifold section of the end plate is a U-shaped bladder member extending entirely around the joint and welded to provide a seal between the end of the duct and the plate. Similar bladder members are provided between adjacent units making up an overall heat exchanger core. |
