Definitions
- the invention relates to the field of cooling of automotive engine engines such as passenger cars, trucks, buses or construction site machines.
- a cooling circuit generally passes through a plurality of mechanical members to be cooled and may also heat some heat-energy consuming elements, connected by tubings or other flexible or rigid conduits in which circulates a heat transfer fluid commonly referred to by the term of cooling liquid.
- the invention more particularly relates to a particular arrangement of the cooling circuit for more effectively dissipating heat to the atmosphere and to improve the overall efficiency of heat exchange between the various mechanical components and elements to be heated of the motor vehicle.
- the cooling circuit of a motor vehicle engine comprises a main circuit called "high temperature" for cooling and regulating the temperature of the engine.
- a main circuit thus comprises a radiator for discharging the heat energy released by the engine and conveyed by the coolant.
- This radiator allows a heat exchange with an ambient air flow depending on the speed of the vehicle and / or the actuation of the fan.
- a pump is also part of this main circuit and allows to adjust the flow of coolant in the circuit.
- a thermostat arranged on the main circuit makes it possible to short-circuit the radiator and thus to heat the coolant more quickly
- the main engine cooling circuit can also be used for different applications, and in particular to cool different equipment.
- these elements are for example and in particular a condenser of the air conditioning circuit of the passenger compartment of the motor vehicle, but also a heat exchanger of the engine cooling oil circuit, the gearbox cooling oil circuit, the circuit compressed air supercharging or the exhaust gas recirculation circuit also called "Exhaust Gas Recycling” (EGR).
- EGR exhaust Gas Recycling
- secondary circuits can be connected to the main cooling circuit.
- the coolant may, in a first embodiment as described in document FR 2 832 185, pass into a radiator dedicated to this secondary loop to lower its temperature below that of the coolant in the main circuit. The coolant then passes into the equipment to be cooled.
- Such a secondary loop is generally referred to as a "low temperature loop" since the coolant temperature is lowered before it is used to cool equipment.
- the different equipment to be cooled do not need to be cooled at low temperature and can be cooled by the main circuit called "high temperature".
- the exhaust gas recirculation system EGR
- the cooling circuit of the recycled gas must allow to lower the temperature of the exhaust gas from a temperature of 600 0 C to about 180 ° C, and therefore a fluid at 0 ° C allows such cooling. It is the same for the cooling circuit of the charge air which must allow to cool the compressed air whose compressor outlet temperature is about 200 0 C to 25O 0 C.
- the ventilation air evacuates, in the radiators, all the heat energy generated by the heat sources.
- the air does not however, it may heat up above the temperature of the cooling liquid in the main circuit.
- the secondary circuits may also be devoid of radiators.
- the main circuit radiator must discharge the additional amount of heat supplied to the coolant.
- motor vehicle cooling circuits comprising two separate cooling loops, one being specifically dedicated to the cooling of the exhaust gas recirculation device (EGR). ).
- a second object of the invention is to reduce the number of elements, in particular by using a single pump, a single expansion tank and a single degassing system for the two cooling circuits.
- the cooling circuit is characterized in that it comprises a first branch of the main loop arranged in parallel with respect to the first radiator.
- This first branch comprises successively, in the flow direction of the coolant flow, a second heat exchanger capturing the heat of a second heat source and a second radiator connected in series by means of hoses for the circulation of the coolant.
- the temperature of the coolant at the outlet of the second exchanger is raised to a temperature greater than or equal to the predetermined threshold value.
- the overheating of the engine could have detrimental consequences on the engine joints or on the internal games allowing the sliding of the pistons inside the cylinders, and in general on the lubrication of the various moving mechanical parts.
- the different equipment connected to this "very high temperature" bypass does not require such temperature regulation, and can withstand much higher temperatures.
- the temperature of the coolant at the outlet of the second exchanger is greater than the temperature of the coolant in the main circuit, in rated speed.
- the heat sources some of the heat energy is removed in the second heat exchanger, may be of different natures.
- the different sources can then be used independently or in combination according to various embodiments of the second exchanger.
- the second exchanger is, for example, of the liquid / gas type in which the gases released during combustion inside the engine, are recovered and cooled by means of the exchanger and pass from a temperature of approximately 600 0 C to about 18O 0 C.
- This lowering temperature is due to the heat exchange with the coolant entering the first branch of the main loop of the cooling circuit.
- the Coolant is therefore at a higher temperature than in the main circuit.
- the second heat source of the second heat exchanger may comprise a circuit of the lubricating oil of the heat engine.
- the second exchanger is of the liquid / liquid type in which the coolant is heated by the engine lubricating oil.
- the second heat source of the second heat exchanger may comprise a supercharged compressed air circuit.
- the second exchanger is, for example, of the liquid / gas type in which the coolant stores heat energy conveyed by the air previously compressed by a device of the compressor or turbocharger type.
- the temperature of the air at the outlet of this type of device is generally of the order of 200 to 25O 0 C.
- radiators of the main loop and the "very high temperature" bypass can be arranged relative to each other in various ways.
- these radiators can be arranged aeraulically in series.
- the air captured by the front face of the vehicle enters successively through the cooling fins of the radiator of the main loop and the first bypass.
- the two radiators are arranged one behind the other, for example perpendicular to the direction of travel of the vehicle corresponding to the direction of the air flow.
- the air which makes it possible to cool the second radiator is at a temperature higher than that of the outside air, ie for example of approximately 100 ° C. when the outside air is at 40 ° C.
- the air temperature is not detrimental since the coolant circulating in the second radiator is also at a higher temperature.
- the air, even heated, can, in the second radiator, cool the coolant.
- the second radiator preferably has dimensions smaller than or equal to the first radiator, and thus does not generate an increase in the overall width and height of the air intake surface on the front of the vehicle.
- a cooling circuit comprising a "very high temperature” bypass makes it possible to increase the dissipated thermal power.
- the first and second radiators may be arranged aeraulically in parallel.
- the two radiators can be cooled by separate air flows, which generates an overall exchange surface greater than the size of the larger of the two radiators.
- This arrangement makes it possible to improve the overall efficiency of the cooling since, in this case, the flow of air passing through the two radiators is at the same temperature corresponding to the temperature of the external environment.
- the two radiators can also be cooled by the same flow of air deflected after passing through the first radiator.
- the flow of air passing through the second radiator is at a temperature greater than that of the air flow passing through the first radiator.
- a thermostat can be positioned on this loop so as to regulate the coolant flow rate as a function of its temperature.
- the first branch can be arranged downstream, in the direction of flow of the coolant, the thermostat arranged on the main circuit.
- the thermostat blocks the circulation of the coolant inside the first radiator, it also blocks the circulation of the coolant in the first bypass.
- the coolant is not cooled and circulates in closed circuit in the first exchanger.
- the first branch may be arranged upstream, always in the direction of circulation of the coolant, a thermostat arranged on the main circuit.
- the thermostat when the thermostat is actuated, the coolant no longer circulates in the first radiator, but it can however flow in the first bypass.
- the first branch may comprise a second thermostat.
- the first branch may comprise a control valve.
- Such a valve thus makes it possible to regulate the flow rate of the cooling liquid in the first bypass.
- the cooling circuit may comprise a second branch of the main loop, arranged in parallel with respect to the first radiator and the first heat exchange, this second bypass may have successively in a direction of circulation of the liquid of cooling, a third radiator and a third heat exchanger capturing the heat of a third heat source connected in series by means of hoses for the circulation of the coolant.
- the cooling circuit may also include a second branch to provide heat at a lower temperature than the main loop.
- This second derivation then plays the role of derivation "low temperature".
- the cooling of the charge air can in particular be carried out in two stages.
- a first cooling by means of the second exchanger of the first bypass "very high temperature” allows a first lowering in contact with the cooling fluid at high temperature.
- a second cooling of the charge air in the third exchanger of the second bypass makes it possible to take advantage of a cooling fluid at low temperature.
- Analogous cycles of using the second heat exchanger as "pre-cooler” and the third heat exchanger as “cooler” can also be used to cool the engine oil or the exhaust gases of the recycling system.
- the first bypass may also include a fourth heat exchanger connected to a circuit for heating the ventilation air of the vehicle cabin.
- This heat exchanger can be arranged parallel to the second radiator, especially at the output of the second heat exchanger of the high temperature loop. Indeed, in this case, the coolant is heated to a very high temperature, before entering the fourth heat exchanger. This supply of heat energy makes it possible in particular to improve the efficiency of the heat transfer.
- FIG. 1 is a schematic representation of a cooling circuit according to the invention
- Figure 2 is a schematic representation of a second heat exchanger capturing the heat released by different elements of the vehicle; Figures 3 to 5 show different variants of the cooling circuit according to the invention.
- the invention relates to a cooling circuit of a motor vehicle engine.
- a cooling circuit of a motor vehicle engine can be reported in particular in the engine compartment of a car, a truck, a coach, a bus or a construction vehicle in particular.

- the main loop 1 comprises a first heat exchanger 2 sensing the heat of a first heat source, a radiator 3 and a pump 4. These various elements are connected in series by means of the hoses 5, 6, 7, 8, 9, 9 .
- the pump 4 makes it possible to circulate the coolant both in the main loop 1 and in the first bypass 11.
- the pump 4 can be arranged anywhere in the main loop 1 or in one of its derivations.
- the first branch 11 is then arranged in parallel with the first radiator
- This first branch 11 comprises a second heat exchanger 12 sensing the heat of a second heat source and a second radiator 13. These two elements are connected in series by means of the hose 16.
- the temperature of the coolant must not exceed a predetermined threshold value TO, generally of HO 0 C.
- TO a predetermined threshold value
- the temperature of the coolant at the outlet of the first heat exchanger is regulated at the temperature T1.
- the temperature T2 of the coolant in the hose 16 downstream of the second heat exchanger 12 is greater than the temperature T1 of the coolant in the upstream hose 15 of it.
- the temperature T1 of the coolant in the main loop is substantially equal to the threshold value TO. Therefore, the temperature T2 of the coolant in the bypass 11 is greater than or equal to the predetermined threshold value TO once the engine is at temperature.
- the first and second radiators 13 may be arranged aeraulically in series.
- the flow of air passing through the first radiator 3 then passes through the second radiator 13 without the need to deflect it.
- the outside temperature may be around 40 ° C. This temperature is then raised after passing through the first radiator 3. This particular arrangement of the two radiators 3.13 one behind the other, limits the air intake surface on the front of the vehicle.
- the second heat exchanger 12 positioned on the branch 11, can capture heat from a plurality of different heat sources arranged in parallel or in series.
- the heat energy captured by the coolant in this exchanger 12 switches the coolant from the temperature T1 to the temperature T2 in the hose 16.
- the one or more heat sources may be formed by, in particular, a circuit 50 of the exhaust gas recirculation system and / or a circuit 60 of the engine lubricating oil and / or a compressed air circuit 70. overeating. Indeed, the temperature of these fluids is much higher than the temperature T1 of the coolant. The temperature difference with the coolant in the high temperature loop is sufficient to ensure satisfactory cooling of the coolant in the second radiator. In this way, the overall efficiency of the heat exchange between the different heat sources and the ventilation air is improved.
- the second radiator 33 of the bypass 11 can also be offset laterally with respect to the rear surface of the first radiator 3.
- the flow of air passing through the first radiator 3 may either be deflected to cool the second radiator 33, or directly evacuated.
- the amount of heat evacuated with equal capture surface is then increased.
- the ventilation air can be captured laterally with respect to the front face of the vehicle and this arrangement makes it possible to improve the efficiency of the heat exchange in the "very high temperature" loop.
- the first bypass 11 may comprise a valve 20 for regulating the flow of the coolant inside the first bypass 11.
- This regulating valve 20 allows, when the latter is closed, to rapidly heat the temperature of the liquid of the cooling liquid in the exchanger 12.
- the valve 21 When the valve 21 is open, the heat exchanger 12 then dissipates a maximum heat energy.
- the main loop 1 may include a thermostat 19, the first bypass 11 being arranged downstream of the thermostat 19.
- a thermostat 19 increases the speed of rise in temperature of the coolant in the main loop 1 to by way of a hose 49 "bypassing" the first radiator 3 and the first bypass 11.
- the first heat exchanger 2 is a closed circuit with the pump 4 and the heat stored by the coolant is not exchanged with the air from the outside environment.
- the three radiators 3, 13, 23 can be arranged in various configurations, namely aeraulically in series or in parallel.
