- the second compartment 20 may include a second entrance 20C2 of the third coolant C.
- This second inlet 20C2 can in particular join the third coolant C coming from the inlet 20C in order to circulate in the fourth circulation paths 100b.
- This second inlet 20C2 can for example make it possible to connect to the second compartment 20 acting as an internal heat exchanger, a second cooler (not shown) for example connected in parallel with the third compartment 30 within the thermal management loop X .
- the third compartment 30 is arranged side by side of the superposition of the first 10 and second 20 compartments. According to this second embodiment, only the first compartment 10 is arranged on the second compartment 20.
- the second end plate 102' of the third compartment 30 is thus not side by side with the second end plate 102 of the first compartment 10 as in the first embodiment, but side by side with the second end plate 103 of the second compartment 20.
- the outlet 30C' of the third heat transfer fluid C of the third compartment 30 is thus connected to the inlet 20C of the third heat transfer fluid C of the second compartment 20.
- this connection is made by a connecting plate 105 delimiting these pipes connecting the outlet 30C' and the inlet 20C and arranged opposite the end plate 103 of the second compartment 20 and the second end plate 102' of the third compartment 30.
- the heat exchanger 1 can also comprise a channel 20A'2 passing through the first 10 and second 20 compartment so as to pro along the outlet 20 A' of the first heat transfer fluid A of the second compartment 20 so that the first heat transfer fluid A emerges through the first end plate 101 of the first compartment 10.
- the outlet 20 A' of the second compartment 20 being here connected at the entrance to this channel 20A'2 by a conduit formed in the connecting plate 105.
- the first 10 and third 30 compartments can be made from two separate stacks of plates 100.
- the side-by-side parts of the first 10 and third 30 compartments can be made from a single stack of plates 100 comprising both the first 100a, second 100b, fifth 100e and sixth 100f circulation paths.
- the second 20 and third 30 compartments can be made from two separate stacks of plates.
- the side-by-side parts of the second 20 and third 30 compartments can be made from a single stack of plates 100 comprising both the third 100c, fourth 100d, fifth 100th and sixth 100f traffic paths.
- the third 30 compartment comprises the same number of plates 100 as the first 10 and second 20 compartment together so that the height of the third compartment is identical to the height of the superposition of the first 10 and second 20 compartments. It is however entirely possible to imagine an alternative in which the third 30 compartment comprises a number of plates 100 distinct from the superposition of the first 10 and second 20 compartments in order to meet the constraints and exchange power demands of heat from said compartments.
- the heat exchanger 1 may also include a fourth compartment 40 for heat exchange.
- This fourth compartment 40 comprises in particular:
- the output 40C 'of the third heat transfer fluid C of the fourth compartment 30 can be connected to the input 20C of the third heat transfer fluid C of the second compartment 20.
- the seventh 100i and eighth 100j circulation paths are stacked alternately.
- the direction of circulation in the seventh lOOi and the eighth lOOj circulation path are against the current in order to improve the heat exchanges between the two fluids.
- the outlet 40C' of the fourth compartment 40 and the outlet 30C' of the third compartment 30 are both connected to the inlet 20C of the third heat transfer fluid C of the second compartment 20.
- the outlet 40C' of the third heat transfer fluid C of the fourth compartment 30 can be free or connected directly to the outlet 20C' of the third heat transfer fluid C of the second compartment 20.
- Figures 13 to 15 show a first variant of this third embodiment in which the third compartment 30 is arranged side by side of the first compartment 10 on a first side and the fourth compartment 40 is arranged side by side of the third compartment 30 on a second side of the third compartment 30 opposite its first side.
- Figures 13 to 15 repeats the characteristic of the second embodiment in which the third compartment 30 is arranged side by side of the superposition of the first 10 and second 20 compartments. So in this example, only the first compartment 10 is arranged on the second compartment 20. It is however quite possible to imagine an embodiment in which both the first 10, the third 30 and the fourth 40 compartments are arranged on the second compartment 20.
- the output 40C 'of the fourth compartment 40 and the output 30C' of the third compartment 30 are both connected to the input 20C of the third heat transfer fluid C of the second compartment 20 via connecting plate 105.
- Figure 16 shows a second variant of the third embodiment in which the third compartment 30 and the fourth compartment 40 are both arranged side by side of the first compartment 10 on a first side.
- the fourth compartment 40 is also arranged side by side of the third compartment 30 on a second side of the third compartment 30 contiguous with its first side.
- the example illustrated in Figure 16 repeats the characteristic of the second embodiment in which the third compartment 30 is arranged side by side of the superposition of the first 10 and second 20 compartments.
- the first compartment 10 is arranged on the second compartment 20. It is however quite possible to imagine an embodiment in which both the first 10, the third 30 and the fourth 40 compartments are arranged on the second compartment 20.
- the heat exchanger 1 by its division into different compartments 10, 20, 30 as well as the different connections of the heat transfer fluid circulation paths, makes it possible to have a compact heat exchanger and which can combine various functions such as a condenser, a cooler and an internal heat exchanger. This allows better compactness for better integration within a motor vehicle.
- the structure of the heat exchanger 1 also allows easier assembly, in particular at the level of the connections with a thermal management device comprising various circulation circuits, because it already incorporates certain connections within it and thus reduces the number necessary connections.
