Abstract

A condenser for an air conditioning circuit is disclosed. The condenser has a housing which is connected to a refrigerating fluid reserve by a flange having cylinder shaped tubes, the housing receiving a first heat exchange portion between the refrigerating fluid and a cooling liquid, the first portion being configured to convey the refrigerating fluid to the refrigerating fluid reserve, and a second heat exchange portion which produces a heat exchange complement between the refrigerating fluid and the cooling liquid at the outlet of the refrigerating fluid reserve.

First claim

The invention claimed is:

1. A condenser for an air conditioning circuit, the condenser comprising:
a housing which is configured to be connected to a single refrigerating fluid reserve positioned outside of the housing, wherein the refrigerating fluid reserve is fixed to a long outer side at a bottom of the housing by a flange comprising two cylinder shaped tubes, wherein the long outer side is longer than at least one side of the housing,
the housing receiving a first heat exchange portion, corresponding to a first partial length of the long outer side, between a refrigerating fluid and a cooling liquid, the first heat exchange portion being configured to convey the refrigerating fluid to the refrigerating fluid reserve, and a second heat exchange portion, corresponding to a second partial length of the long outer side, which is configured to produce a heat exchange complement between the refrigerating fluid and the cooling liquid at an outlet of the refrigerating fluid reserve,
wherein a first end of the fluid reserve is positioned externally adjacent to the first heat exchange portion of the housing, and a second end of the fluid reserve is positioned externally adjacent to the second heat exchange portion of the housing,
wherein the flange is disposed across the first heat exchange portion and the second heat exchange portion.

2. The condenser as claimed in claim 1 , comprising a cooling liquid circuit which is common to the first and second heat exchange portions.

3. The condenser as claimed in claim 1 , comprising a different circuit for each of the first and second heat exchange portions.

4. The condenser as claimed in claim 1 , wherein the housing comprises an assembly of stacked plates which define between them circulation plates of the refrigerating fluid and the cooling liquid in the first and second heat exchange portions, the assembly of stacked plates being configured to provide a circulation path of the refrigerating fluid allowing circulation in series of the refrigerating fluid in the housing, from the first heat exchange portion toward the refrigerating fluid reserve, then from the refrigerating fluid reserve into the second heat exchange portion.

5. The condenser as claimed in claim 4 , wherein the assembly of stacked plates is configured to provide at least one circulation path of the cooling liquid extending in the first and second heat exchange portions.

6. The condenser as claimed in claim 4 , wherein each in the assembly of stacked plates extends with continuity of material in a region of the first heat exchange portion and the second heat exchange portion.

7. The condenser as claimed in claim 4 , wherein the assembly of stacked plates comprises inlet collectors and/or outlet collectors of the refrigerating fluid communicating with the circulation plates of the refrigerating fluid in a region of the first heat exchange portion and/or second heat exchange portion, and/or inlet collectors and/or outlet collectors of the cooling liquid communicating with the circulation plates of the cooling liquid.

8. The condenser as claimed in claim 7 , wherein the inlet collectors and/or outlet collectors of the refrigerating fluid open at one side of the housing and the inlet collectors and/or outlet collectors of the cooling liquid open at an opposite side of the housing which is intended to be opposite the refrigerating fluid reserve.

9. The condenser as claimed in claim 7 , wherein the inlet collectors of the refrigerating fluid in the first exchange portion and outlet collectors of the refrigerating fluid of the second exchange portion open at one side of the housing and the inlet collectors of the refrigerating fluid in the second exchange portion and outlet collectors of the refrigerating fluid of the first exchange portion open at an opposite side of the housing.

10. The condenser as claimed in claim 7 , wherein the assembly of stacked plates extends in a rectangular parallelepipedal volume, the inlet collectors and outlet collectors of the cooling liquid and the inlet collectors of the refrigerating fluid in the first heat exchange portion and outlet collectors of the refrigerating fluid of the second heat exchange portion being orientated parallel along four edges of the housing.

11. The condenser as claimed in claim 7 , wherein the first heat exchange portion comprises partitions which are parallel with the assembly of stacked plates and which are arranged alternately in the inlet collector and outlet collector of the refrigerating fluid of the first exchange portion, in order to direct the refrigerating fluid in the first heat exchange portion in accordance with a plurality of circulation passes of the refrigerating fluid.

12. The condenser as claimed in claim 4 , wherein the assembly of stacked plates is configured to define a barrier to the circulation of the refrigerating fluid between the first heat exchange portion and second heat exchange portion.

13. The condenser as claimed in claim 12 , wherein the assembly of stacked plates, which define the circulation plates of the refrigerating fluid are form by a metal sheet having a raised portion which defines the barrier.

14. A condenser plate of a condenser as claimed in claim 13 .

15. An assembly of a condenser as claimed in claim 1 ; and a reserve.

16. A condenser for an air conditioning circuit, the condenser comprising:
a housing which is configured to be connected to a single refrigerating fluid reserve, the housing receiving a first heat exchange portion between a refrigerating fluid and a cooling liquid, the first heat exchange portion being configured to convey the refrigerating fluid to the refrigerating fluid reserve, and a second heat exchange portion which is configured to produce a heat exchange complement between the refrigerating fluid and the cooling liquid at an outlet of the refrigerating fluid reserve;
wherein the housing comprises an assembly of stacked plates which define between them circulation plates of the refrigerating fluid and the cooling liquid in the first and second heat exchange portions, the assembly of stacked plates being configured to provide a circulation path of the refrigerating fluid allowing circulation in series of the refrigerating fluid in the housing, from the first heat exchange portion toward the refrigerating fluid reserve, then from the refrigerating fluid reserve into the second heat exchange portion,
wherein each plate in the assembly of stacked plates extends with continuity of material continuing from the first heat exchange portion through the second heat exchange portion,
wherein the refrigerating fluid reserve is fixed to a long outer side at a bottom of the housing by a flange comprising two cylinder shaped tubes, and
wherein a first end of the fluid reserve is positioned externally to the first heat exchange portion of the housing, and a second end of the fluid reserve is positioned externally to the second heat exchange portion of the housing,
wherein the flange is disposed across the first heat exchange portion and the second heat exchange portion.
