Definitions
- the invention relates to heat exchangers for motor vehicles.
- It relates more particularly to a heat exchanger capable of being mounted on the intake air circuit of a heat engine.
- Turbocharged combustion engines in particular diesel engines, are supplied by pressurized air, also called “charge air”, coming from a turbocharger actuated by the engine exhaust gases.
- RAS charge air cooler
- turbocharged heat engines are usually equipped with a particle trap. It is known to reduce noise and facilitate the regeneration of this particle trap by heating the intake air using an exchanger supplied by the engine cooling water. This function can be performed by the secondary charge air cooler, also called "precooler”.
- the object of the invention is in particular to overcome the aforementioned drawbacks.
- a simplified construction heat exchanger capable of reducing manufacturing and assembly costs, as well as space.
- it offers a heat exchanger suitable for being mounted on the intake air circuit of a heat engine, which comprises a body divided into a first part having circulation passages for a first primary fluid (which is the engine charge air) and in a second part having circulation passages for a second primary fluid, for example the engine exhaust gases, the body further comprising circulation passages for a secondary fluid, for example a cooling fluid, which is common to the two parts of the exchanger.
- An exchanger is thus produced which combines two parts, and therefore two functions, a first part traversed by the engine charge air and a second part traversed by another primary fluid, which advantageously consists of the engine exhaust gases. .
- the two primary fluids are cooled by the same secondary fluid.
- the second part of the heat exchanger is advantageously traversed by the engine exhaust gases, which makes it possible to cool them before recirculating them towards the engine intake.
- the secondary fluid circulation passages are common to the two parts of the exchanger and pass through them.
- the circulation passages of the first primary fluid and the circulation passages of the second primary fluid are separated by a separation plate placed between the first part and the second part of the body of the exchanger.
- the circulation passages of the first primary fluid comprise an inlet and an outlet opening at a first end of the body of the exchanger, while the circulation passages of the second primary fluid comprise an inlet and a outlet opening at a second end of the exchanger body.
- the circulation passages of the secondary fluid comprise first passages in the first part and second passages in the second part, these first passages and second passages being connected together by watertight seals. This allows you to decouple the first and second passes.
- the body of the heat exchanger can be produced in different ways, it is preferably formed by a stack of shaped plates delimiting circulation blades for a primary fluid, alternating with circulation blades for the secondary fluid, and dividers placed in the primary fluid circulation plates.
- a plate type exchanger is thus produced, the body of which is divided into a first part traversed by the first primary fluid and a second part traversed by the second primary fluid.
- closure plates advantageously include fixing points.
- the separation plate has a passage provided with a valve controlled by an actuator and suitable for being placed:
- the first primary fluid i.e. the engine charge air
- the first primary fluid can circulate in the entire body of the heat exchanger, which facilitates the cooling of charge air.
- the heat exchanger comprises a first valve and a second valve for regulating the flow rate of the first primary fluid and the flow rate of the second primary fluid respectively.
- These two valves are advantageously provided respectively at two ends of the exchanger, preferably on two end plates of the latter.
- the first part and the second part of the exchanger are formed from materials of different nature, in particular from materials resistant to different temperature ranges.
- the first part of the exchanger can be formed in a material of lower resistance, for example aluminum, while the second part of the exchanger can be formed in a material of higher resistance, for example stainless steel.
- the second primary fluid is preferably formed by a recirculation flow rate of the engine exhaust gases.
- the second part of the heat exchanger which forms an auxiliary exchanger, could also be traversed by another fluid.
- FIG. 1 is a schematic sectional view of a heat exchanger according to a first embodiment of the invention
- FIG. 2 is a schematic sectional view of a heat exchanger according to a second embodiment of
- FIG. 3 is a schematic sectional view of a heat exchanger according to a third embodiment of the invention, comprising a valve shown in the closed position;
- Figure 4 is a view similar to Figure 3, showing the valve in the open position
- FIG. 5 is a perspective view of another heat exchanger according to the invention
- - Figure 6 is an exploded perspective view of the heat exchanger of Figure 5;
- FIG. 7 is an end view of the heat exchanger of Figures 5 and 6;
- the heat exchanger 10 shown in Figure 1 is intended to operate in conjunction with a thermal engine of a motor vehicle, in particular a turbocharged diesel engine, operating with charge air.
- the heat exchanger 10 comprises a body 12 divided into a first part 14 and into a second part 16, these two parts being separated by a separation plate 18.
- the body 12 includes circulation passages (not shown in detail) for a first primary fluid FPL which is the supercharging air of the engine.
- These circulation passages (represented diagrammatically by the arrows 20) comprise an inlet 22 and an outlet 24 for the first primary fluid FPL, which are located at the same end of the body 12 of the heat exchanger.
- the second part 16 comprises circulation passages (not shown in detail) for a second primary fluid FP2 which, in the example, consists of the exhaust gases from the engine.
- These circulation passages (represented schematically by the arrows 26) comprise an inlet 28 and an outlet 30 for the second primary fluid FP2, which are located at another end of the body 12.
- the inlet 22 and the outlet 24 are located on one side of the partition 18, while the inlet 28 and the outlet 30 are placed on the other side of this partition 18.
- the fluid FPL passing through the first part 14 and the fluid FP2 passing through the second part 16 are cooled by the same fluid, namely a secondary fluid FS circulating in circulation passages 31 and 32 which are common to parts 14 and 16 and which cross right through.
- the secondary fluid FS is a coolant, typically the coolant of the vehicle engine.
- the secondary fluid FS enters the passage 31 through an inlet pipe 34 and leaves the passage 32 through an outlet pipe 36.
- the pipes 34 and 36 are disposed respectively at the two ends of one heat exchanger. They could however, as a variant, be arranged at the same end of the heat exchanger.
- the body of the heat exchanger is advantageously produced by a stack of plates defining alternating circulation blades.
- the inlet 22 and the outlet 24 of the fluid FPL are advantageously provided on an end plate 38, while the inlet 28 and the outlet 30 of the primary fluid FP2 are advantageously provided on another end plate 40 of the body 12 of the exchanger.
- the inlet 34 of the fluid FS and the outlet 36 of the secondary fluid are disposed respectively on the end plates 38 and 40.
- a first part 14 is used for cooling the charge air and a second part 16 for cooling the recirculated exhaust gases.
- the two primary fluids are cooled by the same secondary fluid FS, which simplifies the construction of the exchanger, therefore reducing its manufacturing and assembly costs, and also the overall size.
- first part 14 and the second part 16 are decoupled, and it is thus possible to make them differently.
- first part 14 and the second part 16 are formed from materials of different nature, for example from materials resistant to ranges of different temperatures.
- the charge air passing through the part 14 is in a temperature range lower than that of the exhaust gases passing through the part 16. Therefore, the part 14 can be made of a material of lesser thermal resistance, for example aluminum, while the second part 16 can be made of a material of higher thermal resistance, for example stainless steel.
- the passage 31 comprises a first passage 31-1 in the first part 14 and a second passage 31-2 in the second part 16.
- the passage 32 comprises a first passage 32-1 in the first part 14 and a second passage 32-2 in the second part 16.
- the first passages 31-1 and 32-1 are connected respectively to the second passages 31-2 and 32-2 by tight seals 42 and 44, which makes it possible to decouple the circulation passages of the first part from those of the second part .
- the seals 42 and 44 are advantageously interposed between two plates 46 and 48 arranged opposite and spaced from one another.
- These plates 46 and 48 are qualified as closing plates insofar as they respectively close the circulation of the first primary fluid FPL in part 14 and that of the fluid FP2 in part 16.
- These closing plates 46 and 48 play the function of separation of the separation plate 18 of FIG. 1.
- the separation plate 18 has a passage 46 provided with a valve 48 controlled by an actuator 50 by via a rod 52 passing through the part 16.
- the actuator 50 may be constituted, for example, by a jack, an electric motor, a micromotor, etc.
- the separation plate 18 is furthermore provided with an opening 54 making parts 14 and 16 communicate.
- the valve 48 can be placed either in an open position ( Figure 4) or in a closed position ( Figure 3).
- Figure 4 In the open position, the circulation passages of the first primary fluid FPL and the circulation passages of the second primary fluid FP2 communicate with each other, so that the primary fluid FPl can circulate in the first part and the second part of the exchanger, as shown by the arrows. This makes it possible to increase the cooling capacity for the primary fluid FPl, the body of the exchanger then being traversed only by the primary fluid FPl.
- the exchanger comprises a first valve 56 mounted on the inlet 22 and a second valve 58 mounted on the inlet 28, which allows to regulate the flow rate of the first respectively primary fluid FPL and the flow rate of the second primary fluid FP2.
- first valve 56 mounted on the inlet 22
- second valve 58 mounted on the inlet 28, which allows to regulate the flow rate of the first respectively primary fluid FPL and the flow rate of the second primary fluid FP2.
- valve 56 is thus advantageously placed on the end plate 38 and the valve 58 on the end plate 40.
- FIGS. 5 to 10 describe a particular embodiment of the invention, which is similar to that of FIG. 1.
- the body 12 of the exchanger is formed by a stack of shaped plates, namely plates 60 and 62 arranged in pairs and alternately.
- the plates 60 and 62 of the same pair delimit between them a circulation plate 64 for a primary fluid, namely for the FPL fluid in the part 14 and for the FP2 fluid in the part 16 (see in particular Figure 8) .
- a blade 66 for the circulation of the secondary fluid FS that is to say the coolant.
- spacers 68 are arranged in the circulation blades 64 of the primary fluids FPL and FP2, as seen in Figures 9 and 10. These spacers are advantageously formed by corrugated metal sheets and they have the function of increasing the exchange surface in the blades 64 traversed by the primary fluids FPl and FP2 which are both gases. Furthermore, the blades 66 traversed by the secondary fluid FS, which is a liquid, are advantageously provided with bosses 73 which have the role of causing a turbulent flow. In the case where, as already indicated, the parts 14 and 16 of the body 12 are made of different materials, the inserts 68 of the first part 14 and the inserts 68 of the second part 16 are also formed of different materials.
- the separation plate 18 comprises two fixing lugs 70 in the form of an ear, projecting outside the plate.
- the separation plate 18 is inserted during assembly between the plates 60 and 62 of the part 14 and the plates 60 and 62 of the part 16.
- the stack of plates 60 and 62 is framed by two end plates 38 and 40 which constitute reinforcing means.
- the plate 38 receives the inlet tubing 22 and the outlet tubing 24 of the fluid FPL, while the plate 40 receives the inlet tubing 28 and the outlet tubing 30 of the fluid FP2.
- the plate 38 also receives, in this embodiment, the inlet pipe 34 and the outlet pipe 36 of the secondary fluid FS.
- the current plates 60 and 62 are generally identical but arranged alternately to define the aforementioned circulation plates.
- the structure of a blade 60 will now be described, it being understood that this description also applies to a blade 62.
- the blade 60 is of generally oblong shape and it comprises a flat bottom 72 provided with bosses, at the ends of which are arranged two openings 74 and 76 of circular shape.
- the openings 74 and the openings 76 are aligned respectively with the inlet tubing 22 and the outlet tubing 24 to allow the circulation of the FPL fluid in the blades 64 of the part 14 (see in particular Figure 8).
- the openings 74 and the openings 76 are aligned respectively with the outlet pipe 30 and the inlet pipe 28 to allow the circulation of the fluid FP2 in the blades 64 of the part 16 (see in particular Figure 8).
- Each blade 60 also has two other openings 78 and 80, also of circular shape, but of smaller diameter than the openings 74 and 76, and arranged close to the latter.
- the openings 78 and 80 come respectively in alignment with the inlet tubing 34 and the outlet tubing 36 to allow the circulation of the fluid FS in the blades 66 both in the part 14 and in the part 16.
- the separation plate comprises two passage openings 82 and 84 arranged respectively in alignment with the openings 78 and 80.
- the opening 84 is visible in FIG. 10.
- the plates 60 are hollow and each surrounded by a peripheral rim 86 raised relative to the bottom 72 and suitable for being joined in leaktight manner with the homologous peripheral rim of an adjacent plate.
- Each plate 60 is advantageously produced by stamping and cutting a metal sheet. It has bowls 88, 90, 92 and 94 respectively surrounding the openings 74, 76, 82 and 84 ( Figure 6).
- the spacers 68 disposed in the blades 66 have undulations defined by generators which extend in the longitudinal direction of the plates so as not to slow the flow of the primary fluids FPl and FP2.
- the entire exchanger is advantageously produced by brazing in a single operation.
- the parts 14 and 16 are traversed respectively by the charge air and the recirculated exhaust gases, while these two primary fluids are cooled by the engine coolant.
- the part 16 of the body 12, which forms an auxiliary exchanger, could alternatively be traversed by a fluid of another nature.
- the invention is particularly applicable to motor vehicles.
