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.

First claim

The invention claimed is:

1. A connecting system for a heat exchanger comprising:
a housing, wherein the housing is formed by a housing top part and a housing bottom part, wherein an outer surface of the housing top part is planar, wherein an outer surface of the housing bottom part is planar,
a first connecting element and a second connecting element, wherein the housing bottom part is connected to the housing top part by a positive and/or material connection between the first connecting element and the second connecting element, wherein the first connecting element is arranged on the housing top part and has a projection which projects from an inner surface of the top part towards the bottom part, wherein the second connecting element is arranged on the housing bottom part has a receiving region which projects from the inner surface of the bottom part towards the housing top part, wherein the first connecting element comprises a cone-type projection having angled sides, wherein the second connecting element comprises a complimentary region to the cone-type projection having angled sides, wherein there is a uniform gap between the cone-type projection and the receiving region when the heat exchanger is in an assembled state, wherein the gap fully encircles the cone-type projection, wherein the cone-type projection comprises a spacing element arranged on an end surface of the cone-type projection, wherein the spacing element projects from the end surface of the cone-type projection towards the receiving region and abuts a parallel surface of the receiving region parallel to the end surface of the cone-type projection such that the gap is also formed between the end surface of the cone-type projection and the parallel surface of the receiving region, wherein the gap is entirely filled by an adhesive, wherein a height of the spacing element is equal to a height of the uniform gap between the cone-type projection and the receiving region.

2. The connecting system for a heat exchanger according to claim 1 , wherein an inner contour of the receiving region substantially follows an outer contour of the cone-type projection.

3. A plate type heat exchanger having a connecting system according to claim 1 , wherein the housing has a fluid inlet and a fluid outlet, via which the heat exchanger is in fluid communication with a fluid circuit.
