Abstract

Heat exchanger and a retention element for the heat exchanger, the retention element having a receiving region and a spacing element, and the receiving region at least partially receiving the heat exchanger, wherein the receiving region has a contour which substantially corresponds to an outer contour of the heat exchanger, the receiving region having fixing means, by means of which the retention element can be fixed to the heat exchanger, the spacing element protruding outwards from the retention element and protruding beyond the outer contour of the heat exchanger.

First claim

The invention claimed is:

1. A heat exchanger and a retention element for the heat exchanger,
the retention element comprising a receiving region, a spacing element, and a stop element, wherein the receiving region at least partially receives the heat exchanger,
the receiving region comprising a contour which substantially corresponds to an outer contour of the heat exchanger, wherein the contour of the receiving region comprises two opposing curved wall regions connected by a bead-like connection region such that the receiving region is w-shaped, wherein the receiving region comprises a fixing device for fixing the retention element to the heat exchanger, wherein the bead-like connection region engages a complimentary portion of the housing of the heat exchanger,
wherein the spacing element protrudes outwards from the retention element and protrudes beyond the outer contour of the heat exchanger,
wherein the stop element is connected to the two opposing curved wall regions and the connection region and determines a maximum insertion depth of the heat exchanger in the receiving region, wherein the stop element is formed by a wall which terminates and bounds the receiving region at one side, wherein the stop element is arranged orthogonally to the two opposing curved wall regions and the connection region.

2. The heat exchanger and the retention element according to claim 1 ,
wherein the fixing device comprises hook-like elements arranged on an end region of the receiving region,
wherein the receiving region surrounds an at least part-region of the heat exchanger which form the fixing device, wherein the hook-like elements engage in recesses of the heat exchanger or engage behind projections of the heat exchanger.

3. The heat exchanger and the retention element according to claim 1 ,
wherein the spacing element is formed by at least one rib, which extends parallel with the stop element and extends orthogonally to the two opposing curved wall regions and the connection region, wherein the spacing element protrudes in an air flow direction of the heat exchanger via the outer contour of the heat exchanger.

4. The heat exchanger and the retention element according to claim 1 ,
wherein the heat exchanger comprises a retention element at both end regions of a collection receptacle.

5. The heat exchanger and the retention element according to claim 1 ,
wherein the receiving region of the retention element is smaller in a disassembled state than a region of the heat exchanger to be surrounded so that, in an assembled state, a pressing force acts on the heat exchanger.

6. The heat exchanger and the retention element according to claim 1 ,
wherein the retention element is formed from plastics material.

7. An air conditioning system comprising a housing for receiving heat exchangers and air channels for passage of air, further comprising a receiving device for receiving the heat exchanger comprising at least one retention element, wherein the heat exchanger and retention element are comprised according to claim 1 .

8. A heat exchanger and a retention element for the heat exchanger,
wherein the retention element comprises a w-shaped receiving region and a spacing element,
wherein the receiving region at least partially receives the heat exchanger,
wherein the receiving region can be inserted through a pipe/rib block of the heat exchanger,
wherein the retention element can be fixed to the heat exchanger by clamping an end region of the receiving region and a stop element.

9. The heat exchanger and the retention element according to claim 8 ,
wherein the end region of the receiving region is formed by hook-like elements which bend back toward the stop element forming acute angles in the end region.

10. The heat exchanger and the retention element according to claim 2 , wherein the at least part-region of the heat exchanger is a collection receptacle.

11. A heat exchanger and a retention element for the heat exchanger,
the retention element comprising a receiving region and a spacing element, wherein the receiving region at least partially receives the heat exchanger,
the receiving region comprising a contour which substantially corresponds to an outer contour of the heat exchanger, wherein the contour of the receiving region comprises two opposing curved wall regions connected by a bead-like connection region, wherein the receiving region comprises a fixing device for fixing the retention element to the heat exchanger,
wherein the spacing element protrudes outwards from the retention element and protrudes beyond the outer contour of the heat exchanger,
wherein the receiving region is w-shaped and comprises two opposing curved wall regions which are connected by a bead-like connection region, wherein the bead-like connection region engages a complimentary portion of the housing of the heat exchanger.

12. The heat exchanger and the retention element according to claim 11 ,
the receiving region further comprising a stop element which determines a maximum insertion depth of the heat exchanger in the receiving region, wherein the stop element is arranged orthogonally to the two opposing curved wall regions and the connection region.

13. The heat exchanger and the retention element according to claim 12 ,
wherein the stop element is connected to the two opposing curved wall regions and the connection region and determines a maximum insertion depth of the heat exchanger in the receiving region, wherein the stop element is formed by a wall which terminates and bounds the receiving region at one side.

14. An air conditioning system comprising:
a housing for receiving the heat exchanger,
air channels for passage of air,
wherein a receiving device on said housing is provided for receiving the heat exchanger having at least one retention element,
wherein the heat exchanger and the at least one retention element are comprised according to claim 11 .
