Abstract

A heat exchange module having a first heat exchanger, configured to enable heat exchange between a first fluid and a flow of air and extending inside a first plane of overall extension, and a second heat exchanger, configured to enable heat exchange between a second fluid and the flow of air and extending inside a second plane of overall extension, is disclosed. A housing delimiting, with the first heat exchanger, a circulation channel for the flow of air is included. The module has at least one air distribution member, movable between a position in which the air distribution member allows the flow of air to pass through the first heat exchanger and the second heat exchanger, and a position in which the air distribution member prevents the flow of air from passing through the first heat exchanger while allowing the flow of air to pass through the second heat exchanger.

First claim

The invention claimed is:

1 . A heat exchange module comprising:
at least two heat exchangers, namely a first heat exchanger, wherein the first heat exchanger is configured to enable heat exchange between a first fluid and a flow of air and extend inside a first plane of overall extension, and a second heat exchanger, wherein the second heat exchanger is configured to enable heat exchange between a second fluid and the flow of air and extend inside a second plane of overall extension; wherein the first plane of overall extension is separate from the second plane of overall extension; at least one housing delimiting, with the first heat exchanger, a circulation channel for the flow of air; and at least one air distribution member, positioned upstream of both the first heat exchanger and the second heat exchanger, which is movable between a first position, in which the air distribution member allows the flow of air to pass through the first heat exchanger and then the second heat exchanger, and a second position, in which the air distribution member prevents the flow of air from passing through the first heat exchanger while still allowing the flow of air to pass only through the second heat exchanger.

2 . The heat exchange module as claimed in claim 1 , wherein the air distribution member comprises at least one flap which can rotate about an axis of rotation belonging to the flap, the heat exchange module comprising an actuator which is intended for operating the flap and is configured to actuate the flap via an axis of operation of the flap, the flap extending between a first longitudinal end and a second longitudinal end of the flap, which ends are comprised inside a plane of overall elongation of the flap, the axis of rotation and/or the axis of operation being able to be inscribed in the plane of overall elongation of the flap.

3 . The heat exchange module as claimed in claim 2 , wherein the axis of rotation and the axis of operation are separate from one another.

4 . The heat exchange module as claimed in claim 2 , wherein the axis of rotation and the axis of operation coincide.

5 . The heat exchange module as claimed in claim 1 , wherein the first plane of overall extension of the first heat exchanger and the second plane of overall extension of the second heat exchanger are concurrent and between them form a first angle (α) of less than 45°.

6 . The heat exchange module as claimed in claim 1 , wherein the first heat exchanger and the second heat exchanger each comprise:
a heat exchange core interposed between a first end plate and a second end plate, and a dimension of the first heat exchanger measured between the first end plate and the second end plate of the first heat exchanger being smaller than a dimension measured of the first end plate and the second end plate of the second heat exchanger.

7 . The heat exchange module as claimed in claim 6 , wherein a first end plate of the first heat exchanger is vertically above a line of the second heat exchanger, the line extending at a first distance corresponding to one third, to within +/−10%, of a total transverse dimension of the second heat exchanger.
