A seal (50), in the cutout portion (28), seals the end of the heat transfer tube (28) with the header plate (18).

A frame (100) for a heat exchanger (1), wherein the frame (100) comprises a first arm (110) and a second arm (120) connectable together in a first connection (141) and in a second connection (142), so that the arms (110, 120) form a loop for encircling the heat exchanger (1), wherein at least one of the arms (110, 120) is adapted to restrict the movement of the heat exchanger (1) with respect to the frame (100) in at least one direction after assembly, characterized in that the first connection (141) is detachable and the second connection (142) enables movement of the first arm (110) with respect to the second arm (120) when the first connection (141) is detached.

A recuperator including a number of neighbouring hexagonal sheets which are connected to each other. Flow passages are formed between neighbouring sheets. Each of the sheets, at its periphery, is at least partially surrounded by and connected to an associated connecting body. Neighbouring connecting bodies are connected to each other at at least a part of the periphery of the associated sheets and together form the wall of a housing. Passage openings are provided in the wall which are connected to the flow passages for allowing air into the flow passages via the passage openings. Neighbouring connecting bodies are provided with protruding parts and with recesses respectively on sides facing each other, wherein the forms of the protruding parts and of the recesses adjoin each other in order to connect the connecting bodies to each other by a press fit. Methods for producing a connecting body and for producing a recuperator.

A heat exchanger is disclosed. The heat exchanger includes a protective device, mutually parallel tubes through which a first fluid circulates, and perpendicular fins connecting two successive flat tubes, a second fluid circulating between said flat tubes by passing through said fins, the protective device being apertured so as to allow the circulation of the second fluid through the fins. The protective device includes fixing spikes which are inserted forcibly between the fins.

A component retention assembly is fixed to an associated part and configured to be engaged with a bracket of a component. The component retention assembly may include a pair of cantilever prongs and a clip. The clip includes a hinge and an extension that is removably disposed between the pair of cantilever prongs when the clip is in a closed position.
