Heat exchanger
View Patent ↗A heat exchanger, such as a condenser or a gas cooler for an air-conditioning system of a motor vehicle, has at least two fin/tube cores which have, on two opposite sides of the fin/tube cores, at least two collecting tubes which can have a flow connection to one another. The collecting tubes can have connecting or junction members which each co-operate with a closure plate or separating plate in order to make the heat exchanger easier to manufacture.
1. A heat exchanger comprising:
at least two fin/tube cores each having a collecting tube on each opposite sides of the fin/tube core, wherein adjacent collecting tubes on a common side of the fin/tube cores are in fluid communication with one another via a passageway extending between the adjacent collecting tubes;
a member received on two of the adjacent collecting tubes; and
a plate engaged with the member and at least partially retaining the member in a position along the two of the adjacent collecting tubes;
wherein an aperture in the member establishes fluid communication between the two of the adjacent collecting tubes.
2. The heat exchanger of claim 1 , wherein the plate extends across at least two adjacent collecting tubes and is received in an opening in the member.
3. The heat exchanger of claim 1 , wherein the plate extends across a single collecting tube and is received in an opening in the member.
4. The heat exchanger of claim 1 , wherein the plate is received within an opening in at least one of the collecting tubes.
5. The heat exchanger of claim 1 , wherein the plate is received within an opening in each collecting tubes; and wherein the openings are located at a common position along the collecting tubes.
6. The heat exchanger of claim 1 , wherein the aperture is defined in the member such that fluid passes in at least one of a first direction entering the member and a second direction exiting the member.
7. The heat exchanger of claim 1 , wherein the plate comprises two adjacent bowl-shaped portions each positioned for insertion into a respective end of a collection tube.
8. The heat exchanger of claim 1 , wherein the aperture establishes a fluid flow path between the collecting tubes that crosses the plate.
9. A heat exchanger, comprising:
a first fin/tube core coupled to a first collecting tube;
a second fin/tube core coupled to a second collecting tube and located adjacent the first collecting tube;
a member shaped to receive and extend about at least a portion of the circumference of each of the first and second collecting tubes; and
a plate received within a portion of the member and at least partially retaining the member in place along the first and second collecting tubes;
wherein the plate is received within an opening on a side of the first collecting tube.
10. The heat exchanger of claim 9 , wherein the first and second collecting tubes are substantially parallel to one another.
11. The heat exchanger of claim 9 , wherein the member also extends to a location between the first and second collecting tubes.
12. The heat exchanger of claim 9 , wherein the member is located at a position disposed from opposite ends of the collecting tubes.
13. The heat exchanger of claim 9 , wherein the member is located proximate adjacent ends of the first and second collecting tubes.
14. A heat exchanger, comprising:
a first fin/tube core coupled to a first collecting tube;
a second fin/tube core coupled to a second collecting tube and located adjacent the first collecting tube;
a member shaped to receive and extend about at least a portion of the circumference of each of the first and second collecting tubes; and
a plate received within a portion of the member and at least partially retaining the member in place along the first and second collecting tubes;
wherein the plate is received within an opening defined between portions of the member extending away from the first and second collecting tubes.
15. The heat exchanger of claim 14 , wherein a portion of the plate is received in an open end of the first collecting tube.
16. The heat exchanger of claim 15 , wherein another portion of the plate is received in an open end of the second collecting tube.
17. The heat exchanger of claim 9 , wherein the plate is received within an opening on a side of the first collecting tube.
18. The heat exchanger of claim 9 , further comprising an aperture in the member and through which fluid flows between a location within the first collecting tube and a location outside of the heat exchanger.
