Abstract

The present invention also concerns a thermal management facility (100) for batteries of electric or hybrid vehicles.

First claim

1 . A heat exchanger comprising:
a circulation device for a first heat-transfer fluid including a first-heat-transfer-fluid inlet and a first-heat-transfer-fluid outlet between which a first heat-transfer fluid flows; and a housing containing the circulation device for the first heat-transfer fluid, the housing including:
at least one opening to be traversed by the first-heat-transfer-fluid inlet and outlet of the circulation device for a first heat-transfer fluid,
a second-heat-transfer-fluid inlet and a second-heat-transfer-fluid outlet between which a second heat-transfer fluid flows.

2 . The heat exchanger as claimed in claim 1 , wherein the circulation device for a first heat-transfer fluid has at least two superimposed heat-exchange tubes.

3 . The heat exchanger as claimed in claim 2 , wherein the heat-exchange tube foul's at least one half turn, the first heat-transfer fluid being designed to flow in parallel in the superimposed heat-exchange tubes.

4 . The heat exchanger as claimed in claim 3 , wherein the heat-exchange tubes are flat.

5 . The heat exchanger as claimed in claim 1 , wherein the circulation device for a first heat-transfer fluid has at least:
one insert interposed between two superimposed heat-exchange tubes of the circulation device for a first heat-transfer fluid, and/or one insert interposed between a heat-exchange tube and the cover or the bottom of the housing.

6 . The heat exchanger as claimed in claim 5 , wherein the insert has an overall corrugated shape.

7 . The heat exchanger as claimed in claim 5 , wherein the insert is in contact with a lower and/or upper heat-exchange tube along a plurality of straight parallel lines.

8 . The heat exchanger as claimed in claim 1 , wherein the at least one opening to be traversed by the first-heat-transfer-fluid inlet and outlet is arranged on one face of the housing that is perpendicular to a lateral face in which the second-heat-transfer-fluid inlet and/or outlet are arranged.

9 . The heat exchanger as claimed in claim 1 , wherein the second-heat-transfer-fluid inlet and outlet are arranged between opposing lateral faces of the housing.

10 . The heat exchanger as claimed in claim 1 , wherein the second-heat-transfer-fluid inlet and outlet are arranged on a single lateral face of the housing.

11 . The heat exchanger as claimed in claim 1 , wherein the housing has a cover and a bottom that are each provided with complementary attachment means.

12 . The heat exchanger as claimed in claim 11 , wherein the complementary attachment means are snap-fitting means.

13 . The heat exchanger as claimed in claim 11 , further comprising a first ring seal interposed between the cover and the bottom of the housing.

14 . The heat exchanger as claimed in claim 13 , wherein one part of the housing, either the bottom or the cover, has a U-shaped peripheral end, a first arm of the U bearing the attachment means, the first ring seal being interposed between the second arm of the U and the peripheral end of the other part of the housing bearing the complementary attachment means.

15 . The heat exchanger as claimed in claim 13 , further comprising a second ring seal interposed between the opening in the housing and the first-heat-transfer-fluid inlet and outlet of the circulation device for a first heat-transfer fluid.

16 . A thermal management facility for batteries of electric or hybrid vehicles, comprising a heat exchanger as claimed in claim 1 , in which:
the first-heat-transfer-fluid inlet and outlet are connected to an air-conditioning circuit, and the second-heat-transfer-fluid inlet and outlet are connected to a cooling water circuit for cooling the batteries.
