- FIG. 1 shows a heat exchange module, designated by the general reference 2. It consists of two exchangers, namely a main heat exchanger, designated by the general reference 4, and a secondary heat exchanger , designated by the general reference 6.
- the main heat exchanger 4 consists of an inlet manifold 8, an outlet manifold 10 and a bundle of circulation tubes 12 interposed between the manifold inlet 8 and outlet manifold 10.
- the inlet manifold 8 has a partition wall 14 which divides it into a main inlet chamber 16 and into a secondary inlet chamber 18.
- the outlet manifold 10 comprises a partition wall 20 which divides it into a main outlet chamber 22 and a secondary outlet chamber 24.
- a inlet manifold 26 is connected to the main inlet chamber 16 and an inlet manifold 28 is connected to the secondary inlet chamber 18.
- the tubing 26 distributes the heat transfer fluid in the tubes of the bundle 12 connected to the main inlet chamber and the inlet tubing 28 distributes the heat transfer fluid in the tubes of the bundle 12 connected to the secondary inlet chamber 18.
- the chamber main outlet 22 has an outlet pipe 30 which allows the outlet of the heat transfer fluid entered by the inlet pipe 26 from the main outlet chamber 22.
- the secondary outlet chamber 24 does not have an outlet pipe, but a passage orifice 32 which puts it in communication with an inlet manifold 34 of the secondary exchanger 6.
- the latter also has an outlet manifold 36 and a bundle of tubes 38 interposed between the inlet manifold 34 and the outlet manifold 36.
- An outlet manifold 40 is connected to the outlet manifold 36.
- the passage orifice 32 can be opened or closed using means d switching which will be described later.
- the bundle of tubes 12 of the main heat exchanger 4 and the bundle of tubes 38 of the secondary exchanger 6 are traversed by the same flow of air shown diagrammatically by the arrow 42.
- the two exchangers are arranged in such a way that 1 the secondary exchanger 6 is cooled first by the air flow 42.
- the tubes of the bundle 12 are therefore cooled by an air flow which has already warmed up in contact with the tubes of the bundle 38 of the secondary exchanger 6.
- the part of the tubes of bundle 12 of . the main exchanger 4 connected to the main inlet chamber 16 and to the main outlet chamber 22 constitutes, in the following, a main radiator 196 (see Figures 15 - 18).
- the heat exchange module 2 can thus generate two temperature levels, for example a high temperature equal to approximately 100 ° C and a low temperature equal to approximately 60 ° C.
- the high temperature radiator is intended to be part of a high temperature circuit and to cool the engine of the motor vehicle, as well as equipment which does not need to be cooled to a low temperature.
- the low temperature radiator is connected to a so-called low temperature network and it is intended for the cooling of fluid for which the temperature level of the engine cooling circuit is too high.
- the circulation of the heat transfer fluid in the heat exchange module 2 of FIG. 1 is carried out as follows.
- the hot fluid of the main circuit, or high temperature circuit enters the main radiator 196 through the inlet pipe 26 of the main inlet chamber, as shown by the arrow 44, passes through the tubes 12 of the bundle connected to the main inlet chamber 16 and enters the main outlet chamber 22.
- the cooled heat transfer fluid leaves the main outlet chamber 22 via the pipe 30, as shown by arrow 46.
- the hot heat transfer fluid of the secondary circuit enters the inlet chamber secondary 18 by the inlet tube 28, as shown diagrammatically by the arrow 48. It traverses the part of the tubes of the bundle 12 connected to the secondary inlet chamber 18 and to the secondary outlet chamber 24. It enters the secondary outlet 24 and passes into the inlet manifold 34 through the passage orifice 32, as shown diagrammatically by the arrows 50. The fluid then travels through the tubes of the bundle 38, from left to right according to the figure, to enter the outlet manifold 36. The cooled heat transfer fluid leaves through the outlet pipe 40, as shown by arrow 52. It is the same heat transfer fluid which circulates in the main radiator and in the secondary radiator.
- FIG. 2 shows a perspective view of an alternative embodiment of the heat exchange module 2 of the
- inlet manifold 8 of the main exchanger 4 comprises a " single inlet tubing 26 instead of the tubing 26 and 28 of the embodiment of Figure 1.
- the inlet manifold 8 does not have a partition wall
- the inlet pipe 26 is used both for the entry of the heat transfer fluid from the main network or high temperature network and the heat transfer fluid from the secondary network or low temperature network, as shown by the arrow 44.
- part of the fluid enters the tubes of the bundle 12 connected to the main outlet chamber 22, and the rest of the fluid enters the portion of the tubes of the bundle 12 connected to the secondary outlet chamber 24.
- the outlet manifold 10 is divided into a main outlet chamber 22 and a secondary outlet chamber by a partition wall 20, in the same manner as in the embodiment of FIG. 1.
- FIG. 3 shows an alternative embodiment of the heat exchange module shown in FIG. 2.
- the latter comprises a single inlet pipe 26 connected to the inlet manifold 8 of the main exchanger 2.
- the manifold inlet 34 of the secondary exchanger 6 comprises a partition 58 which divides it into a lower chamber 60 and an upper chamber 62.
- the outlet manifold 36 of the secondary exchanger 6 comprises a partition partition 64 which divides it into a lower chamber 66 and an upper chamber 68.
- the heat transfer fluid circulates in the tubes of the bundle 38 of the secondary exchanger 6 by performing a series of back and forth movements between the inlet manifold box 34 and the outlet manifold box 36. These back and forth movements are called passes. In the example shown, there are three passes. After entering the lower chamber 60 through the passage orifice 32, as shown diagrammatically by the arrow 70, the fluid circulates from right to left, according to the figure, to enter the lower chamber 66 of the outlet manifold 36.
- FIG. 4 another alternative embodiment of a heat exchange module 2. It differs from the preceding, illustrated and described with reference to Figures 1 to 3, in that the outlet manifold 10 of the main heat exchanger 4 does not have a partition wall which divides its interior volume into two chambers. Consequently, the main radiator, or high temperature radiator 196, merges with the main heat exchanger or high temperature exchanger 4. Likewise, the secondary radiator 200 merges with the secondary heat exchanger 6.
- the circulation of the fluid in this heat exchange module is carried out as follows.
- the heat transfer fluid of the main circuit enters the inlet manifold 8 of the main heat exchanger 4 through the inlet pipe 80, as shown by the arrow 82. It traverses the tubes of the bundle 12, from left to right according to the figure, to reach the outlet manifold 10 from which it emerges cooled by the outlet manifold 84, as shown schematically by the arrow 86.
- the fluid of the secondary circuit, or low temperature circuit enters the manifold 36 of the secondary radiator, - through tubing 88, as shown by arrow 90. It traverses the tubes of bundle 38, from left to right according to the figure, to enter the outlet manifold 34 and exit through tubing 92, as shown by arrow 94.
- the heat exchange module 2 of Figure 4 may also include an orifice. passage 32 connecting the outlet manifold 10 of the main heat exchanger with the inlet manifold 34 of the secondary heat exchanger, as shown. Passage port 32 can be opened or closed by switching means which will be described later. This arrangement makes it possible to vary the exchange capacity of the exchanger by circulating the fluid in all or part of the latter.
- FIG. 5 a fifth alternative embodiment of a heat exchange module 2.
- This embodiment is similar to the embodiment of Figure 4 in the sense that the outlet manifold of the exchanger main heat 4 does not have a partition wall which divides it into a main outlet chamber and a secondary outlet chamber. The interior volume of this box is therefore in one piece. The circulation of the heat transfer fluid in the main heat exchanger 4 therefore takes place in the same manner as in the embodiment shown in FIG. 4.
- the outlet manifold 36 of the main heat exchanger 6 has a partition 96 which divides it into a lower chamber 98 and an upper chamber.
- the heat transfer fluid of the low temperature circuit enters the upper chamber 100 through the inlet tubing 102, as shown by arrow 104. It flows through the upper part of the bundle tubes, located above the partition wall 96, from left to right according to the figure, to arrive in the manifold 34 and to be distributed in the latter, as shown diagrammatically by the arrow 106, then it traverses the lower part of the tubes of the bundle 38, located below the partition of separation 96, from right to left according to Figure 5, to return to the lower chamber 98 of the manifold 36.
- the cooled secondary fluid leaves the lower chamber 98 through the outlet pipe 110, as shown in the arrow 112.
- the radiator secondary thus has two passes. However, it could include more, for example three or four.
- the heat exchange module of FIG. 5 is further distinguished by the fact that the exchange surfaces 114 in heat exchange relation with the tubes of the bundle 12 of the main heat exchanger 4 and 38 of the secondary heat exchanger 6 are formed by corrugated spacers.
- the passage orifice 32 between the manifold 10 of the main heat exchanger 4 and the manifold 34 of the secondary heat exchanger 6 can be opened and closed by switching means .
- switching means There are shown in Figures 6 and 7 two embodiments of such switching means.
- a control member 120 integral with a wall of the inlet manifold 34 of the secondary heat exchanger 6 actuates a rod 122 which carries a piston 124.
- the piston 124 which comprises a seal
- the piston 124 moves away from the opening of the passage orifice 32, which allows the circulation of the fluid, as shown schematically by the arrows 128.
- the embodiment of the control means is identical, except for the fact that the piston 124 is located inside the outlet manifold 34 of the secondary exchanger 6 instead of being located inside the outlet manifold 10 of the main exchanger 4.
- the piston 124 moves away from the tubular spacer 126, which opens the passage orifice 32 and allows the passage of the fluid, as shown schematically by the arrows 128 .
- the exchangers are assembled in a single operation by brazing.
- the exchangers are assembled partly by brazing and partly by mechanical means.

- the main network also includes a bypass on which is mounted a heating radiator 190, also called an air heater.
- it may also include a bypass on which are mounted heat exchangers which exchange heat with the heat transfer fluid of the main network and which are intended for cooling vehicle equipment such as a gas cooler. exhaust 192 or an engine lubricating oil cooler 194.
- the main network includes a bypass on which the main radiator 196 is mounted, and a bypass line 198 which allows the main radiator 196 to be short-circuited.

- the low temperature radiator 252 is mounted in series with a condenser 204 forming part of an air conditioning circuit of: the passenger compartment of the motor vehicle.
- the exchangers 254 and 256 are permanently part of the high temperature circuit, while the exchanger 252 is permanently part of the low temperature circuit.
