Abstract

A receiving box for a heat exchanger may include a box body delimiting at least one duct formed in the box body. The box body may include a plurality of receptacles configured to receive a plurality of tube bodies of the heat exchanger. The plurality of tube bodies may each be fluidically connected to the at least one duct. The box body may define an injection tube that extends along the at least one duct and is separated from the at least one duct via the box body. The injection tube may include at least one outlet opening fluidically connected to the at least one duct.

First claim

The invention claimed is:

1. A receiving box for a heat exchanger, comprising:
a box body defining a plurality of ducts;
the box body including a plurality of receptacles configured to receive a plurality of tube bodies of the heat exchanger, the plurality of tube bodies each fluidically connected to at least one of the plurality of ducts;
wherein the box body defines an injection tube that extends along the plurality of ducts and is separated from the plurality of ducts via the box body;
wherein the injection tube includes at least one outlet opening fluidically connected to an associated duct of the plurality of ducts;
wherein the box body further includes an outer wall that defines a first duct of the plurality of ducts and a second duct of the plurality of ducts in the box body on an outer side;
wherein the box body further includes a central web that partially defines the first duct and the second duct in the box body, and which separates the first duct from the second duct;
wherein the plurality of receptacles includes a plurality of first receptacles disposed in the outer wall of the box body, the plurality of first receptacles fluidically connected to the first duct and configured to receive a plurality of first tube bodies of the plurality of tube bodies;
wherein the plurality of receptacles further includes a plurality of second receptacles disposed in the outer wall of the box body, the plurality of second receptacles fluidically connected to the second duct and configured to receive a plurality of second tube bodies of the plurality of tube bodies; and
wherein the central web is structured to form the injection tube.

2. The receiving box according to claim 1 , wherein the at least one outlet opening opens directly into the associated duct.

3. The receiving box according to claim 1 , wherein:
the central web is double-walled including a first wall and a second wall;
the first wall of the central web partially defines the first duct in the box body; and
the second wall of the central web partially defines the second duct in the box body.

4. The receiving box according to claim 1 , wherein a through flow cross section of the injection tube is smaller than a through flow cross section of each of the plurality of ducts.

5. The receiving box according to claim 1 , wherein an opening flow area via which the at least one outlet opening is connected to the associated duct is disposed at an angle of 30° to 170° relative to a receptacle flow area of at least one receptacle of the plurality of receptacles that extends into the associated duct.

6. The receiving box according to claim 1 , wherein the box body further includes a connection opening for fluidically supplying the receiving box, and wherein the injection tube further includes an inlet opening disposed on an end side of the injection tube and fluidically connected to the connection opening.

7. The receiving box according to claim 6 , wherein the associated duct is fluidically connected to the connection opening via the at least one outlet opening.

8. The receiving box according to claim 1 , wherein the at least one outlet opening includes at least two outlet openings that are disposed spaced apart from one another along the injection tube.

9. The receiving box according to claim 1 , wherein the box body is composed of a cohesive material.

10. A heat exchanger, comprising:
a plurality of tube bodies through which a first flow path for a first fluid extends;
the plurality of tube bodies arranged in a second flow path for a second fluid, the second fluid path fluidically separated from the first flow path; and
a receiving box including a box body defining at least one duct;
the box body including:
a plurality of receptacles configured to receive the plurality of tube bodies of the heat exchanger; and
a double-walled portion defining an injection passage;

the injection passage extending along the at least one duct and separated from the at least one duct via a wall of the double-walled portion of the box body;
the wall of the double-walled portion including at least one outlet opening fluidically connecting the injection passage to the at least one duct;
wherein the plurality of tube bodies are received in the plurality of receptacles and are each fluidically connected to the at least one duct; and
wherein the first flow path extends through the receiving box.

11. The heat exchanger according to claim 10 , wherein the box body further includes a connection opening for fluidically supplying the receiving box, and wherein the wall of the double-walled portion further includes an inlet opening disposed on an end side of the injection passage and fluidically connected to the connection opening.

12. A receiving box for a heat exchanger, comprising:
a box body defining a plurality of ducts;
the box body including a plurality of receptacles configured to receive a plurality of tube bodies of the heat exchanger, the plurality of tube bodies each fluidically connected to an associated duct of the plurality of ducts;
the box body further including a double-walled central web separating the plurality of ducts;
the double-walled central web including:
a first wall at least partially defining a first duct of the plurality of ducts;
a second wall at least partially defining a second duct of the plurality of ducts; and
an injection passage defined by and between the first wall and the second wall;

wherein the injection passage extends along at least one duct of the plurality of ducts; and
wherein at least one of the first wall and the second wall includes a plurality of outlet openings that fluidically connect the injection passage to a respective duct of the plurality of ducts.

13. The receiving box according to claim 12 , wherein the plurality of outlet openings respectively extend into the respective duct.

14. The receiving box according to claim 12 , wherein a through flow cross section of the injection passage is smaller than a through flow cross section of at least one duct of the plurality of ducts.

15. The receiving box according to claim 12 , wherein the plurality of outlet openings are disposed spaced apart from one another in a longitudinal direction of the injection passage.

16. The receiving box according to claim 12 , wherein an opening flow area via which at least one of the plurality of outlet openings is connected to the respective duct is disposed at an angle of 30° to 170° relative to a receptacle flow area of at least one receptacle of the plurality of receptacles that extends into the respective duct.

17. The receiving box according to claim 1 , wherein the central web is formed by at least one portion of the outer wall.

18. The receiving box according to claim 1 , wherein:
a first end of the outer wall is bent around to contact an intermediate portion of the outer wall and form the first duct;
a second end of the outer wall, which is disposed opposite the first end, is bent around to contact the intermediate portion of the outer wall and form the second duct; and
