The tank includes a recessed region between two parts of the tank and the elongate member extends through an aperture defined in each of the parts, such that an exposed portion of the elongate member is outside the tank. The second heat exchanger is mounted to the exposed portions of two elongate members of the first heat exchanger via connecting unit.

Abstract: A header plate includes slots to receive heat exchange tubes of a heat exchanger. Each slot includes a lip extending in a direction of the tubes. Each slot has straight sides and corners. At least two tabs extend from each lip. One tab is on one side of each lip, and another tab is on an opposite side of each lip. Tabs are absent from the corners of the lip. Each tab is turned out from the lip so that the tabs on the lip act as a lead in for a tube entering the slot. Each slot has two long sides opposite one another. At least one tab is on each long side of the lip.

Abstract: A mounting assembly for mounting a heat exchanger comprises an elongate member defining a screw threaded axial bore at each end, and a bolt for each screw threaded bore. The assembly further comprises two elastomeric parts each being substantially top hat shaped and defining an axial bore to receive one end of the elongate member, such that the assembly can be mounted between two apertured mounting parts by arranging the heat exchanger between the mounting parts, with the elongate member received in a bore through the heat exchanger, and tightening the bolts so that the mounting part is clamped between the end of the elongate member and the bolt head, with the elastomeric parts mounting the mounting assembly in the heat exchanger bore so that resilient compression of the elastomeric parts allows movement of the heat exchanger with respect to the elastomeric parts.

Abstract: The present disclosure relates to an assembly forming a heat exchanger or part of a heat exchanger. The assembly comprises a core with at least one insert in the form of a side plate, and a header plate attached to the or each insert by at least one snap fit connection. Accordingly, the assembling process of the assembly can be facilitated, and cost of the assembly can be reduced.

Abstract: Two side channels are for mounting the first heat exchanger. Each side channel defines a back and two side walls protruding from the back. An elongate member is at each end of a tank of the first heat exchanger. Each elongate member extends through the tank and being attached at each end to one of the side walls of one of the two channels so that the elongate member spans the channel to mount the first heat exchanger to the channel. The tank includes a recessed region between two parts of the tank and the elongate member extends through an aperture defined in each of the parts, such that an exposed portion of the elongate member is outside the tank. The second heat exchanger is mounted to the exposed portions of two elongate members of the first heat exchanger via connecting unit.

Abstract: A heat exchanging apparatus comprises a first heat exchanger, oil cooler, arranged to allow ambient air to pass therethrough and a second heat exchanger, radiator, adjacent the first heat exchanger and arranged to allow air exiting the first heat exchanger to pass therethrough. The apparatus further comprises a third heat exchanger comprising two or more interconnected heat exchanging cores, charge air coolers. Each core is arranged to allow ambient air to pass therethrough.

Abstract: A heat exchanger includes a core and a pair of end tanks attached to the end of the core. Each end tank extends over an outermost peripheral end of the core such that the core extends into a chamber defined by the end tank. The end tank is welded to the core at the outer surface of the core and a lower end surface of the tank.
