Definitions
- the present invention relates to the field of heat exchangers and more particularly to the field of tri-fluid plate heat exchangers for motor vehicles allowing heat energy exchanges between two separate heat transfer fluids and a third heat transfer fluid.
- Plate heat exchangers generally comprise a stack of plates forming different superimposed circulation spaces in which the various heat transfer fluids pass. A separate heat transfer fluid circulates in each circulation space. A first heat transfer fluid generally circulates in alternating circulation spaces over the entire height of the stack of plates. The second and third heat transfer fluids for their part circulate in separate circulation spaces between two circulation spaces in which the first heat transfer fluid circulates. The second and third heat transfer fluids thus each circulate over part of the height of the stack of plates.
- One of the aims of the present invention is therefore to at least partially overcome the drawbacks of the prior art and to provide an improved tri-fluid heat exchanger.
- the present invention therefore relates to a tri-fluid heat exchanger comprising a stack of plates and:
- a third circulation circuit of a third heat transfer fluid between a third inlet manifold and a third outlet manifold of the third heat transfer fluid the stack of plates forming an alternation of first and second heat transfer fluid circulation spaces stacked in the direction of the stack of plates, the first circuit being arranged within the first circulation spaces and the second and third circuits being arranged jointly within the second circulation spaces.
- the first circulation circuit has at least two passes within the same first circulation space.
- the second and third circulation circuits each comprise at least two passes within the same second circulation space.
- the second and third circulation circuits are arranged side by side so that the second circulation circuit is arranged in line with a first passes from the first circulation circuit and the third circulation circuit directly above a second pass from the first circulation circuit.
- the second and third circulation circuits are intertwined so that a pass of the first circulation circuit is arranged simultaneously in line with a passes from the second (12) t to the third circulation circuit.
- the circulation of the first heat transfer fluid in the first circulation spaces is countercurrent to the circulation of the second and third heat transfer fluids in the second circulation spaces.
- the plates have at least one rib configured to define the path of the passes.
- each circulation space comprises a first and a second plate contiguous to one another defining said circulation space, in the stack, the second plate of a space of circulation being in contact with the first plate of the adjacent circulation space and vice versa.
- the plates have a curved profile with side edges, the plates being nested one inside the other, the side edges of two adjacent plates overlapping so as to form the circulation spaces.

- first element or second element As well as first parameter and second parameter or even first criterion and second criterion, and so on.
- first element or second element As well as first parameter and second parameter or even first criterion and second criterion, and so on.
- indexing does not imply a priority of an element, parameter or criterion with respect to another and it is easily possible to interchange such names without departing from the scope of the present description.
- This indexation does not imply an order in time, for example, to assess this or that criterion.
- FIGS 1 and 2 show a tri-fluid heat exchanger 1 respectively shown schematically in section and in exploded perspective.
- This tri-fluid heat exchanger 1 comprises a stack of plates 20a, 20b, 20c, 30a, 30b, 30c (visible in Figures 5 and 6) forming an alternation of first A and second B heat transfer fluid circulation spaces stacked in the direction of the stack of plates 20a, 20b, 20c, 30a, 30b, 30c.
- the tri-fluid heat exchanger 1 also comprises a first circulation circuit 11 of a first heat transfer fluid between a first inlet manifold 11a and a first outlet manifold 11b of the first coolant fluid.
- the tri-fluid heat exchanger 1 further comprises a second circulation circuit 12 of a second heat transfer fluid between a second inlet manifold 12a and a second outlet manifold 12b for the second heat transfer fluid.
- the tri-fluid heat exchanger 1 further comprises a third circulation circuit 13 of a third heat transfer fluid between a third inlet manifold 13a and a third outlet manifold 13b for the third heat transfer fluid.
- the first coolant can for example be a refrigerant used in an air conditioning circuit such as, for example, C02, R134a or R1234y.
- the second heat transfer fluid can in turn be glycol water circulating in a thermal management circuit, for example batteries of an electric or hybrid vehicle.
- the third heat transfer fluid can also be a heat transfer fluid such as glycol water circulating in another thermal management circuit.
- the first circulation circuit 11 is arranged within the first circulation spaces A and the second 12 and third 13 circulation circuits are arranged jointly within the second circulation spaces B. Therefore, the second 12 and third 13 circulation circuits do not each take up a circulation space A or B and can each allow exchanges of heat energy with the first circulation circuit 11. The size of the heat exchanger 1 can thus be contained.
- the circulation circuits 11, 12, 13 have a single pass per circulation space A, B.
- FIG. 3 more particularly shows a representation of the first circulation circuit 11 within the first circulation space A.
- the first circulation circuit 11 comprises a first pass 110a starting from the first inlet manifold 11a and crossing the first circulation space A along its length.
- the first circulation circuit 11 has a second pass 110b connected to the end of the first pass 110a opposite the first inlet manifold 11a. This second pass 110b crosses the first circulation space A along its length and joins the second inlet manifold 11b.
- the first 110a and second 110b passes are side by side and separated by a wall 115.
- the first collectors 11a and 11b are arranged on the same side of the first circulation space A.
- the second 12a, 12b and third 13a, 13b collectors cross right through the first circulation space A and are isolated so that they cannot be in fluid communication with the first circulation circuit 11 or between them.
- the second 12a, 12b and third 13a, 13b collectors are aligned and disposed on the first circulation space A opposite the first collectors 11a, 11b.
- FIG. 4 shows a representation of the second 12 and third 13 circulation circuits within the second circulation space B.
- the second circulation circuit 12 comprises a first pass 120a starting from the second inlet manifold 12a and crossing the second circulation space B along its length.
- the second circulation circuit 12 comprises a second pass 120b connected to the end of the first pass 120a opposite to the second inlet manifold 12a. This second pass 120b crosses the second circulation space B over its length and joins the second inlet manifold 12b.
- the first 120a and second 120b passes are side by side and separated by a wall 125.
- the third circulation circuit 13 has a first pass 130a starting from the third inlet manifold 13a and crossing the second circulation space B along its length.
- the third circulation circuit 13 has a second pass 130b connected to the end of the first pass 130a opposite the third inlet manifold 13a. This second pass 130b crosses the second circulation space B along its length and joins the second inlet manifold 13b.
- the first 130a and second 130b passes are side by side and separated by a wall 135.
- the second 12 and third 13 circulation circuits are arranged side by side so that the second circulation circuit 12 is arranged in line with a first pass 110a of the first circuit circulation 11 and the third circulation circuit 13 in line with a second pass 110b of the first circulation circuit 11.
- the second 12 and third 13 circulation circuits are separated by another wall 145.
- the second and third collectors 12a, 12b, 13a and 13b are arranged on the same side of the second circulation space B.
- the first collectors 11a, 11b cross right through the second circulation space B and are isolated so that they cannot be in fluid communication with the second 12 and third 13 circulation circuits 11 or between them.
- the second 12a, 12b and third 13a, 13b collectors are aligned and disposed on the second circulation space B opposite the first collectors 11a, 11b.
- FIGS 5 and 6 show a cross-sectional view of the circulation spaces A and B.
- each circulation space A, B has a first 20a, 30a and a second 20b, 30b plate contiguous to one another defining said circulation space A, B.
- the first circulation space A can be formed by a first 20a and a second 20b plate.
- the second circulation space B can be formed by a first 30a and a second 30b plate.
- the second plate 20b, 30b of a circulation space A, B is in contact with the first plate 20a, 30a of the adjacent circulation space A, B and vice versa.
- Walls 115, 125, 135 and 145 may be ribs made on the plates 20a, 20b, 30a and 30b and configured to define the path of the passes 110a, 110b, 120a, 120b, 130a, 130b.
- said plates 20c, 30c may have a curved profile with side edges 21c, 31c.
- the plates 20c, 30c are nested one inside the other and the side edges 21c, 31c of two adjacent plates 20c, 30c overlap so as to form the circulation spaces A, B.
- the walls 115, 125 , 135 and 145 may be ribs made on the plates 20c and 30c and configured to define the path of the passes 110a, 110b, 120a, 120b, 130a, 130b.
- FIGS 7 to 9 show a second embodiment of the first A and second B circulation spaces comprising at least two passes.
- the circulation spaces A, B can be formed by two plates 20a, 20b, 30a, 30b or else a single plate 20c, 30c as described above.
- the second 12 and third 13 circulation circuits are not arranged side by side but are intertwined so that a pass 110a, 110b of the first circulation circuit 11 is disposed simultaneously in line with a pass 120a, 120b, 130a, 130b of the second 12 and of the third 13 circulation circuit 13.
- one of the passes 130a, 130b of the third circuit of circulation 13 is disposed between the first 120a and the second 120b pass of the second circulation circuit 13.
- the various passes 120a, 130a, 120b and 130b can thus be separated by a single wall 155 making a zigzag-shaped path in the second space circulation B.
- This wall 155 can, as before, be a rib made on the plate or plates 30a, 30b, 30c forming the second circulation space B.
- the second manifolds 12a, 12b are no longer aligned with the third collec teurs 13a, 13b but offset due to the intertwining of the passes 120a, 120b, 130a, 130b.
- the first collectors 11a, 11b for their part pass right through the second circulation space B and are isolated so that they cannot be in fluid communication with the second 12 and third 13 circulation circuits 11 or between them. .
- the first circulation space A remains identical to the first embodiment except that the second 12a, 12b and third 13a, 13b collectors are arranged at different locations.
- the passes 110a and 110b have a less rectilinear path than according to the first embodiment but a more tortuous path due to the locations of the second 12a, 12b and third 13a, 13b collectors.
- the circulation of the first heat transfer fluid in the first circulation spaces A can be countercurrent to the circulation of the second and third heat transfer fluids in the second circulation spaces B.
- the first pass 110a of the first circulation circuit 11 can be arranged directly above the second pass 120b of the second circulation circuit 12 and the first pass 130a of the third circulation circuit 13.
- the second pass 110b of the first circulation circuit circulation 11 can be placed directly above the first pass 120a of the second circulation circuit 12 and the second pass 130b of the third circulation circuit 13.
