Definitions
- the present invention concerns the field of cooling circuits for thermal engines and relates to a central module, forming an integral structure before installation, for such a circuit.
- Cooling circuits currently tend to comprise more and more sub-circuits for additional functionality, whereas the space available under the engine bonnet and in particular around the engine unit is limited.
- the invention applies more particularly to a cooling circuit for vehicles with an internal combustion engine which comprises, in particular, a main portion of circulation circuit for cooling the cylinders and cylinder heads, a feed pump, a heat exchanger for exhaust gases, a radiator of a main unit heater dissipating the recovered heat in the surrounding medium, a radiator of a secondary unit heater dissipating the recovered heat in the vehicle body, the two unit heaters and the exchanger being installed in three respective circulation sub-circuits mutually set up in shunt or in parallel after the main portion of the circulation circuit and forming therewith a multi-branched circulation loop, said main portion incorporating in a single segment said feed pump connected, upstream, to said three sub-circuits and, downstream, to the cooling means for the cylinders and cylinder heads.
- the object of the invention is to reduce the space required for such a circuit, the number of component parts to be installed and assembled in situ, as well as the duration of installation, the cost and the complexity of the cooling liquid circulation loops.
- the idea behind the invention is to incorporate different portions of the circuit into a single prefabricated structure in the form of a central module for a cooling circuit of the above-mentioned type, said module being characterised in that it forms a rigid hollow body with a plurality of cavities, made up by the assembly of three structural sub-modules, namely a first sub-module comprising a hollow part with a flow distribution chamber, two portions of conduits of the sub-circuit supplying the radiator of the main unit heater, one portion of conduit of the sub-circuit supplying the radiator of the secondary unit heater and one portion of conduit of the sub-circuit supplying the heat exchanger, a second sub-module comprising at least a part of the casing of the heat exchanger, additional portions of conduits of the sub-circuit supplying this latter and an
- a cooling circuit 2 comprising in particular a main portion 3 of a circulation circuit for cooling the cylinders 4 and cylinder heads 4', a feed pump 5, a heat exchanger 6 for exhaust gas, a radiator 7' of a main unit heater 7 dissipating the recovered heat in the surrounding medium, a radiator 8' of a secondary unit heater 8 dissipating the recovered heat in the vehicle body, the two radiators of the unit heaters and the heat exchanger 6 being installed in three respective circulation sub-circuits 9, 10 and 11 mutually set up in shunt or in parallel after the main portion of the circulation circuit 3 and forming therewith a multi-branched circulation loop, said main portion 3 incorporating in a single segment said feed pump 5 connected, upstream, to said three sub-circuits 9, 10 and 11 and, downstream, to the cooling means for the cylinders and cylinder heads (illustrated by broken lines in the engine unit 4"), comprising a water/oil exchanger (labelled "modine
- said module 1 forms a hollow, rigid body with a plurality of cavities, made up of three structural sub-modules 1', 1" and 1"'.
- a first sub-module 1' comprises a hollow part 12 with a flow distribution chamber 12', two portions of conduits 13, 13' of the sub-circuit 9 supplying the radiator 7' of the main unit heater 7, a portion of conduit 14 of the sub-circuit 10 supplying the radiator 8' of the secondary unit heater 8 and a portion of conduit 15 of the sub-circuit 11 supplying the heat exchanger 6.
- a second sub-module 1" comprises at least a part of the casing 16 of the heat exchanger 6, additional portions of conduits 17, 17' of the sub-circuit 11 supplying the latter and an additional portion of conduit 18 of the sub-circuit 9 supplying the radiator 7' of the main unit heater 7.
- a third sub-module 1"' comprises the feed pump 5, end portions of conduit 19, 19' and 19" respectively of the sub-circuit 9 supplying the radiator 7' of the main unit heater 7, of the sub-circuit 11 supplying the heat exchanger 6 and of the sub-circuit 10 supplying the radiator 8' of the secondary unit heater 8 and portions of conduit 20 and 20' forming a part of the common segment of the main portion 3 of circuit extending upstream and downstream of the feed pump 5.
- the first 1' and third 1" modules are assembled with the second module 1" in the region of the two assembly zones ZA1 and ZA2 situated at two opposite ends thereof, assembly being achieved by fitting together mating portions of conduit of the same sub-circuits which are part of the various sub-modules 1', 1" and 1"', a primary adjusting means 21 being installed in the sub-circuit 9 supplying the radiator 7' of the main unit heater 7 and a second adjusting means 22 being installed in the sub-circuit 11 supplying the heat exchanger for exhaust gas 6.
- the central module 1 groups together relatively large portions of the main parts of the cooling circuit into a predefined and reproducible arrangement in accordance with the layout of said circuit, facilitating its installation, its connection and its maintenance and reducing its bulk (reduction of empty spaces between pipes, best use of available space).
- the latter For assembly of the first and third sub-modules 1' and 1" with the second sub-module 1", the latter comprises straight ends of portions of conduits, forming male parts, whereas said two other sub-modules 1' and 1"' have ends of portions of conduits which are flared or enlarged over a certain depth, allowing close fitting of the straight ends of the portions of the second sub-module 1' (the presence of internal collars forming abutments).
- connection zones for the sub-circuits concerned 9 and 11 will be locked together by cooperating assembly plates which receive fixing means (for example combinations of screws and nuts) and are sealed by compression joints, for example O-rings.
- fixing means for example combinations of screws and nuts
- the latter advantageously has an elongate structure with three-dimensional extension, extending after installation over at least two faces of the engine unit 4".
- the sub-modules 1', 1" and 1"' are made of a thermoplastic material, the first 1' and the third 1"' sub-modules being formed by the vibration welding of two integrally moulded parts, the second sub-module 1" being formed all in one piece.
- the first 1' and the second 1" sub-modules consist essentially of two conduit structures set up side by side.
- the third sub-module 1"' has a joint face 23 going through the housing of the feed pump 5, one of the two halves thereof being formed all in one piece with a mounting and coupling flange 24 of a drive motor 25 for said pump 5.
- the central module 1 can comprise, in addition, a portion of conduit 26' of a segment of circuit 26 for charging the feed pump 5 connected, externally to the module 1, to a degassing reservoir 27 into which open two parallel segments of the degassing circuits 28, 28', one 28 of which is fluidically connected to the radiator 7' of the main unit heater 7 and the other 28' of which is fluidically connected at the top of the hollow part 12 to the flow distribution chamber 12', said integrated portion of conduit 26' of the segment of charging circuit 26 incorporating an adjusting means 29 for the flow going through said segment 26 and the hollow part with the distribution chamber 12 comprising a housing 12" for a temperature sensor.
- Such a cooling circuit illustrated schematically in fluid form, is known in particular from French patent application No. 02 08794 of 12 July 2002 in the name of the applicant.
- the interfaces of external connections of the portions of conduits forming parts, incorporated in said module 1, of the sub-circuits 9, 10 supplying the radiators 7', 8' of the two unit heaters 7, 8, of one of the segments of degassing circuits 28', of the segment of charging circuit 26 and of the part 20 of the portion of main circuit 3 extending upstream of the feed pump 5, are in the form of joining pieces 30 made all in one piece with the respective corresponding sub-module 1', 1' 1"', the hollow part 12 with the distribution chamber 12' having an inlet opening 31 surrounded by a fixing flange 31' for a tight fitting to the outlet from the engine unit 4" of the main portion of the circulation circuit 3 in the region of the cylinder heads 4'.
- the proportional or open and shut valve 22 corresponding to the adjusting means for sub-circuit 11 supplying the heat exchanger 6 consists of an added part, the body 22' of which forms part of said sub-circuit 11 and in the region of its inlet and outlet openings has respective fixing flanges 32, 32' for tight fitting to a flange 33 of the outlet opening of the casing 16 of the heat exchanger 6 and to the end portion of conduit 19' of the sub-circuit 11 supplying the heat exchanger 6 which is an integral part of the third sub-module 1"'.
- Said end portion of conduit 19' will of course be fitted with an adapted complementary fixing flange 19"'.
- the adjusting means 22 for the flow in the sub-circuit 11 supplying the heat exchanger 6 and the adjusting means 29 for the flow in the segment of the charging circuit 26 for the feed pump 5 are in the form of a single valve device 34 with two inlets and one outlet, for example a linear valve, the flows coming from the above-mentioned sub-circuit 11 and segment of circuit 26 being combined in the region of the outlet opening of said double valve.
- adjusting means 21 the actuator of which is installed in a protective box 21', could possibly correspond to a proportional control valve such as that known from French patent application No. 2 805 878 of 1 March 2000 in the name of the applicant, or French patent application No. 01 16314 of 17 December 2001 also in the name of the applicant.
- the loss of head in the sub-circuit 11 supplying or going through the heat exchanger 6 for exhaust gas is substantially equivalent to the loss of head in the sub-circuit 9 supplying or going through the radiator 7' of the main unit heater 7.
- the present invention also relates to a cooling circuit for a vehicle with an internal combustion engine, characterised in that it comprises a central module 1, as described above, connected to the cooling means of the cylinders 4 and cylinder heads 4', to the radiators 7' and 8' of the main unit heater 7 and the secondary unit heater 8 and, if need be, to a degassing reservoir 27, via portions of tubing or adapted sleeves.
- the management of the flow in this circuit 2 will be effected by controlling the adjusting means 21, 22 and 29.
