Abstract: The invention relates to a heat exchanger (1), in particular for a motor vehicle. The heat exchanger (1) includes a plurality of tubular bodies (2) stacked onto one another along a stack direction (S), which in each case delimit a first fluid path (3a) for being flowed through by a refrigerant (K). The individual tubular bodies (2) are arranged along the stack direction (S) spaced apart from one another, so that between intermediate spaces (4) formed between the tubular bodies (2) that are adjacent in the stack direction (S), each form a second fluid path (3b) fluidically separated from the first fluid paths (3a) for being flowed through by air. The individual tubular bodies (2) extend transversely, preferentially perpendicularly to the stack direction (S) along a longitudinal direction (L).

Abstract: A heat exchanger arrangement having at least a first heat exchanger and having a second heat exchanger, wherein the first heat exchanger has a first heat transfer matrix with a first air intake surface and with a first air outlet surface, and wherein the second heat exchanger has a second heat transfer matrix with a second air intake surface and with a second air outlet surface, wherein the first heat exchanger and the second heat exchanger are arranged adjacent to one another in such a manner that the first air outlet surface is opposite the second air intake surface and the two heat exchangers are arranged one behind the other in a primary direction of airflow, wherein at least one sealing strip is arranged on at least one lateral side region of the two heat exchangers or on both lateral side regions of the heat exchangers.

Abstract: A closure plug for a collector of a refrigerant circuit with a substantially cylindrical base body with a circumferential wall, wherein a first circumferential groove, in which an O-ring is arranged, is provided in the circumferential wall, wherein an elastomer ring is injection molded onto the circumferential wall at an axial distance from the first circumferential groove.
