Definitions
- Cooling system for vehicle engine with water circuit and oil circuit
- the invention relates to cooling systems for a vehicle engine.
- Such a system is known from EP-1 277 932, in the embodiment of FIG. 1.
- This system comprises a module comprising an oil filter and an oil cooler.
- the module is coupled to the oil circuit by being connected to an oil pump and to the engine crankcase.
- the module is coupled to the water circuit so that it communicates with a water pump, a radiator and the cylinder block. Precisely, the water leaving the module is transmitted to the water pump, then sent from it into the cylinder block. At the outlet of the cylinder block, a fraction of the water passes through the radiator to join the module while another fraction enters the module without passing through the radiator.
- This arrangement has the disadvantage that it is relatively bulky, complicated to implement and relatively unreliable due to the large number of interfaces.
- An object of the invention is to make the system more compact, simpler to implement and more reliable.
- a cooling system for a vehicle engine comprising: - a module comprising an oil cooler and a filter;
- the system according to the invention may also have at least one of the following characteristics:
- the module has a water inlet extending upstream of the cooler
- the module has a water outlet extending downstream of the cooler
- the duct extends upstream of the water outlet; - it includes a water pump extends year! downstream of the exit ⁇ 'B ⁇ I ⁇ ;
- the modufe includes a huila filter relaxing downstream of the cooler
- the module has an inlet Hufe relaxing upstream of at least one of the filter, and the refroid ⁇ ss ⁇ ur dratti conduit, and preferably the charges;
- the module exhibiting a relaxing oil outlet downstream from at least one of the filter, the cooler and the oil duct, and preferably all three.
- FIG. 1 is a diagram illustrating the water circuits and eight systems according to the preferred embodiment of the invention:
- FIG. 2 is a diagram similar to FIG. 1 showing more precisely the spatial arrangement of the ducts
- FIGS. 3 and 4 show two partial sectional views of a filtering and cooling module of the system of FIG. 1 illustrating respectively the circuit and the oil circuit;
- FIG. 5 and 6 are views respectively illustrating the two main outer faces of the module of Figures 3 and 4.
- This system 2 is a cooling system and a fiirfige for a motor vehicle engine
- the system comprises a filtering and cooling module 4. This module is connected to a water circuit 6.
- the system comprises : also a
- the pump at 10 is intended to put water in the circuit
- oil circuit Lo 8 radiator serves to cool: water in th water circuit!.
- the module comprises a refrûldisseor of iiule 14 and an oil filter 16.
- the oil cooler referred to cool the oil by means of the water flowing through Ie cool heart, L® filter howling is operable to purify oil that
- the water circuit 6 comprises a single water conduit 20 connecting a
- the module 4 Downstream of the water inlet 22, the module 4 comprises a terminating y ⁇ branch 24 which divides the flow of eay this conduit between on the one hand the oil refeeder 14 and ⁇ , water diversion duct 28 mounted parallel to the cooler
- L @ module 4 comprises a branch 27 extend downstream of the cooler and the water flow from the cooler is mixed with the water debut from the bypass duct 26.
- the set the reconstituted flow comes to a single output oau 28 modulates intêgrale ⁇ iert 4 and is transmitted to an input! pumped water from the water 10.
- the conduit 25 dp bypass 26 has flow control means AAU: formed for example by a nozzle 30 disposed downstream cte i 'arn ⁇ nt end of the "armature and upstream of its end av ⁇ I.
- the fraction of this flow passes through the oil cooler, while the fraction of the flow circumvents it by means of the bypass duct.
- of oil from the oil pump 11 enters into an input of single oil 32 modyte 4 It then reaches a branch 34 extending ⁇ n $ val of this task.
- a fraction of this flow pgr a first branch 42 of Terri bra ⁇ cliarnert and reaches the ⁇ ? oil filter 16, the complementary fraction of this flow is sent into an oil duct 36, then to the eThuite cooler 14, leaving the cooler ur.
- this complementary fraction enters a second oil inlet of the oil filter.
- the two fractions of this flow are combined inside the oil title and come out in the form of a single flow through a filter outlet.
- the module 4 is thus connected to the other system members by only four pipes that put in communication respectively ⁇ ⁇ with the radiator the water pump, the pomf "oil and the housing.
- all the flow of sau from the engine passes through module 4, i & il ensures distribution of water and oil in Téchang core 14 ⁇ al thee oil filter 18 in a minimum space requirement and no external stitching.
- the module 4 is attached to the cylinder cylinder 12 of the engine . interface of the module with the casing cy ⁇ ndre, one recovers the .j dèbi oil coming from Is pump to liai the. This oil is filtered and partially cooled before emerging to the main engine ramp by the same interface. As an see, the flow of water and oil s® cross at self! modute and this, for efficiency closed heat exchanges.
- H ⁇ v ⁇ jrrtlûri encompasses filter functions and Huite ";) rafr ⁇ idisseir oil on a carrier which acts as iuyao made of water to transfer the flow rate: the water to the radiator water pompa housing in a minimal footprint and without external bypass.
- the oil filter is M of the rechargeable type, it is arranged in a housing integrated in the support. A plastic cover removably closes it in order to make the cartridge accessible for its replacement.
- the oil is a standard POE type oil.
- the cooler has a specific interface adapts itself to the mountings of the support. The interface is designed to be able to pass through its flow and scream on both sides with a tight fit suitable for two fluids.
- the module 4 also makes it possible to avoid pressure drops on the water and hut circuits.
- the cooler 14 extends downstream of the radiator B into the water circuit.
- the oil circuit comprises an oil bypass conduit causing a fraction of the flow from the ictement in the oil filter without passing through is what has been described above, and d # indêpe ⁇ dam ⁇ i ⁇ nt ⁇ different, characteristics presented £> $ rf®s us about the circuit configuration of water, especially EI ⁇ d participate ⁇ ridarn ment milk that extends refra ⁇ dîsseur ⁇ not downstream of the radiator in the wall.
