- inlet pipe 62 which is connected to the inlet pipes 54 and 58 and a pipe of outlet 64 connected to outlet pipes 56 and 60.
- a fluid F1 can supply in parallel the two circuits C1 and C2 as in the case of FIG. 1.
- the heat exchanger can include plus an input bypass 66 connected to the first tubing 54 and an output bypass 68 connected to the first outlet pipe 56, which makes it possible to supply only the first C1 circuit (central circuit) by a fluid F2 as shown by the arrows.
- This fluid F2 is advantageously different from the fluid F1.
- the heat exchanger heat further comprises selection means for allow either the supply of pipes 62 and 64, or the supply of leads 66 and 68.
- these selection means include a set of two valves 70 and 72 ( Figures 5 and 6) mounted respectively on the pipeline inlet 62 and outlet pipe 64 and a another set of two valves 74 and 76 mounted respectively on the input bypass 66 and the output bypass 68.
- the air conditioning mode corresponds to the operating mode shown in Figure 5.
- valves 70 and 72 are open, while valves 74 and 76 are closed. It results that circuits C1 and C2 are supplied jointly and traversed by the same fluid F1.
- the fluid F1 is advantageously refrigerant and the heat exchanger is working then as an evaporator to produce cold.
- the additional heating mode corresponds to operating mode shown in Figure 6.
- valves 70 and 72 are closed, while valves 74 and 76 are open. It As a result, only the circuit C1 is supplied by the fluid F2.
- Fluid F2 is also a refrigerant, but when the circuit C1 is only supplied by the fluid F2, the evaporator then functions as a condenser, to produce heat.
- valves 70, 72, 74 and 76 are deleted and replaced here by two non-return valves 78 and 80, one of which is mounted on the first inlet pipe 54 between the inlet pipe 62 and input bypass 66 and the other is mounted on the first outlet pipe 56 between the pipe of output 64 and output bypass 68.
- Circuits C1 and C2 can be supplied jointly by the fluid F1, the valves 78 and 80 not opposing the circulation of the fluid.
- check valves 78 and 80 allow only the circulation of the fluid F2 in the exchanger.
- each of the first channels 14 is bounded by a U-shaped tube 82 and each channels 16 is delimited by a U-shaped tube 84, each tube 82 being “wrapped” by a tube 84.
- the tubes 82 and 84 pass through a multiplicity 86 flat fins to increase heat exchange between the fluids traveling respectively through the circuits C1 and C2 and an air flow A which scans the beam.
- Tubes 82 communicate with an inlet manifold 88 and an outlet manifold 90 and, likewise, the tubes 84 communicate with a manifold inlet 92 and an outlet manifold 94.
- the F1 and F2 circuits can each be powered by identical or different fluids.
- Feeding means selective or not, of the type described with reference to Figures 1 to 8, can therefore be provided.
- Figure 10 shows an example of a circuit of a heat exchanger heat functioning as an evaporator (air conditioning mode), circuits C1 and C2 being both supplied by a cold fluid F1.
- Supply channels 36 and 38 include respective internal partitions 96 and 98 ( Figure 1) placed in selected places, so that these channels have sections of different lengths, for example a section 100 of length L1 and a section 102 of length L2 such that L1 is less than L2 ( Figure 10). this allows to ensure a selected distribution of the fluid F1 between the first channels 14 and the second channels 16.
- FIG. 11 shows an example of a circuit of a heat exchanger heat functioning as a condenser (heating mode additional), only one of the circuits C1 and C2 being supplied by a hot fluid F2.
- the circuits are the same as in the case of FIG. 10, but the second channels 16 are not not supplied and constitute "dead channels" represented schematically by broken lines.
- the first circuit C1 and the second circuit C2 are suitable for being traversed by a fluid cold F1
- the first circuit C1 is suitable for being traversed alone by a hot fluid F2. So we can predict that the first circuit C1 and the second circuit C2 are clean to be traversed by a refrigerant allowing cool the surrounding air, and that the first circuit C1 is suitable to be traversed by itself by a coolant dissipating heat.
