Abstract

A heat exchanger with mutually adjacent first flow channels and second flow channels. The first flow channels and the second flow channels are received in a first manifold at a first end region of the flow channel end regions and in a second manifold at a second end region of the flow channel end regions. The first manifold has a first base and the second manifold has a second base, the first base and second base having a plurality of openings in which the end regions of the flow channels are received. The first manifold has a first longitudinal channel and a second longitudinal channel. The second manifold has a second cover which together with the second base of the second manifold forms transverse channels, and one first flow channel and one second flow channel are fluidically connected to each other via a respective transverse channel.

First claim

What is claimed is:

1. A heat exchanger comprising:
mutually adjacent first flow channels;
second flow channels;
a first header having a first base and a first cover;
a second header having a second base and a second cover;
wherein the first flow channels and the second flow channels, at a first end region, are received in the first header and at a second end region, are received in the second header,
wherein the first base and the second base have a plurality of openings in which the first and second end regions of the first and second flow channels are received,
wherein the first cover has a first longitudinal channel, a second longitudinal channel and pockets that extend from one side surface of each of the first longitudinal channel and the second longitudinal channel, the pockets forming space-apart side channels that each extend in an axial direction that is perpendicular to an axial direction of each of the first longitudinal channel and the second longitudinal channel,
wherein the first flow channels are in fluid communication with the first longitudinal channel and the second flow channels are in fluid communication with the second longitudinal channel,
wherein the second cover of the second header, together with the second base of the second header, forms cross channels,
wherein the first flow channels and the second flow channels are each in fluid communication with one another via the cross channels,
wherein the first base and the second base, on the longitudinal sides, have at least partially upstanding edge regions, which laterally close the first and second longitudinal channels, the cross channels and the pockets, and
wherein the upstanding edge regions have a bottom edge region, which is formed by at least one continuous material strip, and wherein a plurality of crenellated sealing elements upwardly extend from the bottom edge region.

2. The heat exchanger according to claim 1 , wherein the pockets are each arranged in alignment with one of the openings of the first base and with the first end regions of the first and second flow channels.

3. The heat exchanger according to claim 1 , wherein the second cover has a wave-like contour in a longitudinal section with wave troughs and wave peaks, wherein the wave troughs are in contact with the base of the second header, and wherein the wave peaks together with connecting elements, that connect the wave peaks to the wave troughs, form the cross channels.

4. The heat exchanger according to claim 3 , wherein the wave-like contour is made as a rounded wave profile or as a rectangular profile or as a trapezoidal profile.

5. The heat exchanger according to claim 1 , wherein the openings in the first base and the second base have passages, and wherein the passages are directed away from the interior of the first header and the second header, respectively, toward the first and second flow channels.

6. A heat exchanger comprising:
mutually adjacent first flow channels;
second flow channels;
a first header having a first base and a first cover;
a second header having a second base and a second cover;
wherein the first flow channels and the second flow channels, at a first end region, are received in the first header and at a second end region, are received in the second header,
wherein the first base and the second base have a plurality of openings in which the first and second end regions of the first and second flow channels are received,
wherein the first cover has a first longitudinal channel, a second longitudinal channel and pockets that extend from one side surface of each of the first longitudinal channel and the second longitudinal channel, the pockets forming space-apart side channels that each extend in an axial direction that is perpendicular to an axial direction of each of the first longitudinal channel and the second longitudinal channel,
wherein the first flow channels are in fluid communication with the first longitudinal channel and the second flow channels are in fluid communication with the second longitudinal channel,
wherein the second cover of the second header, together with the second base of the second header, forms cross channels,
wherein the first flow channels and the second flow channels are each in fluid communication with one another via the cross channels
wherein the first base and the second base, on the longitudinal sides, have at least partially upstanding edge regions, which laterally close the first and second longitudinal channels, the cross channels and the pockets, and
wherein the upstanding edge regions have fixing elements via which the first cover and the second cover are fixable to the first base and the second base, respectively.

7. The heat exchanger according to claim 2 , wherein the pockets in the first cover are formed by indentations, which are introduced in an edge running laterally parallel to the first longitudinal channel and to the second longitudinal channel and merge into the first longitudinal channel or the second longitudinal channel.

8. The heat exchanger according to claim 2 , wherein the cross channels and pockets have a variable cross section.

9. The heat exchanger according to claim 1 , wherein at least one of the first longitudinal channel or the second longitudinal channel have one or more partition walls that divide the at least one of the first longitudinal channel or the second longitudinal channel into a number of sections.

10. An arrangement of a heat exchanger according to claim 1 in a climate control system, wherein the heat exchanger is a two-row condenser and is arranged within a climate control unit of a climate control system, wherein the first flow channels form a first row and the second flow channels form a second row, and wherein a first fluid flows through the first flow channels and the second flow channels and a second fluid flows around the first flow channels and the second flow channels.

11. The heat exchanger according to claim 5 , wherein the passages surround each of the openings in the first base and the second base such that each opening is surrounded by a respective passage, and wherein each passage protrudes from an exterior surface of one of the first base or the second base.

12. The heat exchanger according to claim 5 , wherein the passages are spaced apart from one another.

13. The heat exchanger according to claim 1 , wherein a total number of pockets is equal to a combined total number of the first flow channels and the second flow channels.

14. The heat exchanger according to claim 1 , wherein the sealing elements are aligned with the pockets, such that each respective sealing element laterally closes a respective one of the pockets.

15. The heat exchanger according to claim 6 , wherein the upstanding edge regions have a bottom edge region, which is formed by at least one continuous material strip, and wherein a plurality of crenellated sealing elements upwardly extend from the bottom edge region and wherein the fixing elements and the sealing elements alternate in position along the upstanding edge region.
