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.

First claim

What is claimed is:

1. A heat exchanger arrangement comprising:
a first heat exchanger having a first heat transfer matrix with a first air intake surface and with a first air outlet surface; and
a second heat exchanger having 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 such that the first air outlet surface is opposite the second air intake surface and the first and second 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 first and second heat exchangers or on both lateral side regions of the first and second heat exchangers, the at least one sealing strip providing a lateral sealing between the first heat exchanger and the second heat exchanger,
wherein the at least one sealing strip is an injection-molded sealing strip that has an injection-molded hard component on which a soft component is molded, and
wherein the at least one sealing strip is attached to either the first heat exchanger or the second heat exchanger and the soft component of the at least one sealing strip extends in a direction from either the first heat exchanger or the second heat exchanger, to which the at least one sealing strip is attached, towards the other of the first heat exchanger or the second heat exchanger to provide the lateral sealing between the first heat exchanger and the second heat exchanger.

2. The heat exchanger arrangement according to claim 1 , wherein the at least one sealing strip is arranged on both lateral side regions of the first and second heat exchangers.

3. The heat exchanger arrangement according to claim 1 , wherein the hard component is made of a thermoplastic material, a polyamide, or polypropylene, and/or wherein the soft component is made of an elastomer or a thermoplastic elastomer.

4. The heat exchanger arrangement according to claim 1 , wherein the hard component is made of a thermoplastic material and at least one additive, including fibers, particles, spheres, and/or rods that are made of glass or carbon.

5. The heat exchanger arrangement according to claim 1 , wherein the at least one sealing strip has a bar that is part of the hard component, wherein the bar provides for stability of the at least one sealing strip and is provided to attach the at least one sealing strip to either the first heat exchanger or the second heat exchanger.

6. The heat exchanger arrangement according to claim 5 , wherein an attachment is provided on the bar to attach the at least one sealing strip to either the first heat exchanger or the second heat exchanger.

7. The heat exchanger arrangement according to claim 5 , wherein at least lone first tab-like element that is part of the hard component is provided on the bar, wherein the at least one first tab-like element projects from the bar and serves to hold the soft component.

8. The heat exchanger arrangement according to claim 7 , wherein at least one second tab-like element that is part of the soft component is provided on the bar, wherein the at least one second tab-like element projects from the bar and from the at least one first tab-like element, and wherein the at least one second tab-like element is used for sealing.

9. The heat exchanger arrangement according to claim 8 , wherein the at least one second tab-like element includes two second tab-like elements that are part of the soft component, the two second tab-like elements being spaced apart from another and being provided on the bar.

10. The heat exchanger arrangement according to claim 9 , wherein a recess is provided along the bar between the two second tab-like elements for the passage of a portion of either the first or second heat exchanger, a pipe, or a connecting flange.

11. The heat exchanger arrangement according to claim 6 , wherein the attachment provided on the bar attaches directly to either the first heat exchanger or the second heat exchanger.
