Abstract: The application relates to a heat exchanger and a connecting system for the heat exchanger. This subject matter includes a housing formed by a top part and a bottom part and a first connecting element and a second connecting element connected to these top and bottom parts. Specific embodiments of the subject matter are shown in which the connecting elements connect the housing top part and bottom part by a positive and/or material connection. The advantages of each embodiment over prior approaches are too numerous to include in this abstract, but will be apparent to one of ordinary skill in the art when reviewing the full specification.

Abstract: Heat exchanger having a housing, having a first fluid port and having a second fluid port, wherein the housing is in fluid communication with a fluid source via the fluid ports, wherein the housing can be traversed by a flow of a fluid, wherein the housing is of multi-part design and has a housing upper part and a housing lower part, wherein the housing upper part and/or the housing lower part has a base region and an at least partially encircling turned-up edge region, wherein housing the two parts are formed from a plastic or a fiber composite material.

Abstract: The invention relates to a heat exchanger with a first and a second collecting tank, with at least one tube arranged between the two collecting tanks, each having a fluid inlet and a fluid outlet. At least one tube end is in fluid communication with a collecting tank and is connected to the collecting tank via a form-fitting and/or integrally bonded connection, wherein the opening is surrounded by an opening edge.

Abstract: Heat exchanger having a housing, having a fluid inlet and having a fluid outlet, wherein the heat exchanger is in fluid communication via the fluid inlet and the fluid outlet with a fluid circuit, having a flow-guiding element in the interior of the housing, wherein the housing is formed from a substantially planar housing upper part and a substantially trough-like housing lower part, wherein the housing lower part has a base region and an encircling side wall, wherein the housing lower part is formed by a supporting structure and an encasement and the supporting structure is at least partially surrounded by the encasement, wherein the supporting structure is formed from a metallic material, and the encasement is formed substantially from a plastic, wherein the housing upper part is formed from a plastic and the housing lower part is connected to the housing upper part substantially by means of plastic-on-plastic contact.

Abstract: Heat exchanger having a first collecting box and having a second collecting box, having at least one tube arranged between the two collecting boxes, wherein a fluid inlet and a fluid outlet are provided which are arranged individually on in each case one of the collecting boxes or on a single one of the collecting boxes, wherein the tube is received at the ends in an opening in in each case one of the collecting boxes and is in fluid communication with the collecting boxes, wherein the opening is surrounded by an opening edge whose contour corresponds to the outer contour of the tube, and in that the opening is designed such that the opening cross section narrows toward the interior of the collecting box and the tube can be inserted, under preload at the circumference, into the opening.
