- each blade 133 is formed of a strip, for example metal, assembled, in particular by brazing or the like, on the last plate 124 and the penultimate plate 124.
- the insert 127 consists of two distribution compartments 135a and 135b disjoint.
- the two distribution compartments 135a and 135b are identical.
- the two distribution compartments 135a and 135b are arranged in point symmetry with respect to each other. Accordingly, the two distribution compartments 135a and 135b respectively define the input circulation channel 128a and the output circulation channel 128b.
- the insert 127 consists of a dispensing device 136, consisting of a single piece, comprising two distribution chambers 136a and 136b.
- the two distribution chambers 136a and 136b are identical.
- the two distribution chambers 136a and 136b are arranged in point symmetry with respect to each other.
- constituent walls of the insert 127 advantageously extend, respectively, in the first direction and the second direction, as shown in Figure 8a.
- at least one of the constituent walls of the insert 127 may form an angle with the first direction and / or the second direction, as shown in Figure 8b.
- Such particular arrangements make it possible to locate the inlet of the second fluid 121 and the outlet of the second fluid 122 in an optimal configuration.
- FIGS. 9a to 9c are schematic views of the last plate 24 of the heat exchanger 100 according to respective integration variants in the air conditioning loop 2 of the air conditioning system 1.
- the last plate 124 is provided with a connection element 140 making it possible to connect the heat exchanger 100 to the other components of the air conditioning loop 2 and / or the secondary loop 18 of the air conditioning system 1.
- the connecting element 140 is the expansion member 5 of the air conditioning loop 2 or any other constitutive component of the air-conditioning loop 2 and / or the secondary loop 18.
- the connection element 140 comprises a inlet opening 141 and a discharge opening 142 of the second fluid which are, respectively, in fluidic relation with the inlet of the second fluid 121 and the outlet of the second fluid 122.
- the connecting element 140 comprises a major axis A passing through the centers of the intake opening 141 and the discharge opening 142.
- the connecting element 140 is positioned so that the major axis A forms a given angle with the first median axis x, between 0 ° and 90 °, for example of the order of 45 °.
- the angle is equal to 0 °
- the angle is equal to 90 °
- the angle is equal to 45 °.
