Abstract: The present disclosure relates to a heat exchanger including a plurality of fluid guiding metal pipes (2) having pipe ends (3) arranged side by side at intervals, at least one pipe bottom (4) made of plastic and having receiving through-holes (5) in which the pipe ends (3) may be received, and a collection box (6) made of plastic and which may be connected to the pipe bottom (4) by a locking device formed between the pipe bottom and the collection box, wherein a seal (9) may be inserted between the pipe bottom (4) and the collection box (6), and the seal ensures press-fit of the pipe bottom (4) on the pipe ends (3) and seals the collection box (6) against the pipe bottom (4) and the pipe bottom (4) against the pipe ends (3).

Abstract: The present disclosure relates to a heat exchanger that is characterized by including at least one collector and at least one tube, in which case the tube is installed in the collector by at least one seal disposed between the collector and the tube in such a manner that fluid connection is possible between the collector and the tube, wherein the tube includes at least one reinforcing element. The present disclosure also relates to a method of installing a heat exchanger and a method of manufacturing a heat exchanger, in which case at least one tube is installed in at least one collector by at least one seal disposed between the collector and the tube in such a manner that fluid connection is possible between the collector and the tube, wherein at least one reinforcing element is provided in or to the at least one tube.

Abstract: The present disclosure relates to a heat transfer system 1 for transferring heat between a first fluid and a second fluid. The system 1 has an arrangement 2 composed of pipe elements 3, 3a, 3b, 3c for passing through the first fluid, one or more pipe bottoms 5 having a through opening 6, and one or more sealing elements 7 having a through opening 8. The pipe elements 3, 3a, 3b, 3c are formed of a flat pipe having a first region 10 having a first height X and a width W and one or more second regions 11 having a support surface 13 arranged on one end portion of the pipe elements 3, 3a, 3b, 3c and having a second height Y, respectively. The sealing element 7 is arranged between the edge of the through-hole 6 of the pipe bottom 5 and the support surface 13, respectively, and has a specific wall thickness G. The pipe elements 3, 3a, 3b, 3c having a wide side are arranged in a state aligned parallel to each other and at an interval F with respect to each other in the first region 10.

Abstract: A device for heat transfer between a first fluid and a second fluid includes an assembly of tube elements for conducting the fluid and have a first, nondeformed region and a second, deformed region, disposed at an end of the tube element. A tube plate with passage apertures and a sealing element with passage apertures are provided. The sealing element is disposed between an outer surface of the second region of a tube element and an edge of a rim of the passage aperture of the tube plate. Tube elements are developed as flat tubes with flow channels. Flow channels are separated from one another by an internal structure element. A system and a method for the manufacture of the device are also provided.
