    Ky! System in a vehicleBACKGROUND OF THE INVENTION AND BACKGROUND ARTThe present invention relates to a cooling system in a vehicle according to the preamble of claim 1.
    During combustion processes in the cylinders of the internal combustion engine, heat energy is created whichheats the connecting areas in the cylinder block and cylinder head. The areas thatis closer to the combustion chamber obtained at a higher temperature than the areas which are located at a stone distance from the combustion chamber. There are then warmer and colder zones in the cylinder block and cylinder head of the combustion engine during operation of an internal combustion engine. In the event of operation dathe combustion engine is loaded hard for a long period of time, the warmer zones can be offthe cylinder block and the cylinder head obtain a very high temperature.
    Conventional cooling systems for cooling internal combustion engines circulate cooling fluid which during normal operation can have a temperature in the range 80-90 ° C. Da cool watercirculating through the internal combustion engine cooling ducts provide all cooled zones inthe internal combustion engine a cooling rned coolant of essentially the same temperature. In the case of operation when a combustion engine is heavily loaded, the cooling may be deficient in the hottest zones of the cylinder block and the cylinder head.
    DE 102011117102 discloses a cooling system threaded by a circulating cooling vessel which can cool oneinternal combustion engine crankcase and cylinder head. The cooling system consists of a high-temperature cooling circuit and a low-temperature cooling circuit. Cooling fluid can be averaged between the two cooling circuits with the help of valves. The temperature of the cooling vessel in the respective cooling circuits can thus be varied. The cooling water from the low temperature cooling circuit can be ledthrough a lower warmer section of the internal combustion engine cylinder head and coolantfrom the high temperature cooling circuit can be passed through an upper cooler section of the cylinder head. Thus, the lower vanitating section of the cylinder head can be cooled with a cooling liquid which has a lower temperature than the cooling liquid which cools the lower cooler section of the cylinder head. This cooling system is complicated to control and it contains i.a.valves that are expensive to procure.2SUMMARY OF THE INVENTIONThe object of the present invention is to provide a cooling system which has an uncomplicated control and relatively few components which can be procured at a relativelylow cost while being able to reliably cool different zones on a reliable saltan internal combustion engine riled coolant of different temperatures.
    This object is achieved with the initially defined cooling system which can be characterized by the features stated in the characteristic part of the claim. The cooling system includesA first line of conductors is connected to a radiator and a first thermostat that regulatessupply of coolant to the cooler depending on the temperature of the coolant. The first conduit portion has a similar design to a conventional cooling system. The cooling system further comprises a second conduit portion which directs the cooling liquid through atminstory a first zone of the internal combustion engine, and a third conduit portion which conductscoolant through a second zone of the internal combustion engine heated to a bearingtemperature in the first zone during operation of the internal combustion engine. The second conduit portion comprises a second cooler which had the capacity to cool the coolant to a lower temperature than in the first cooler and a second thermostat which regulates the supply of coolant to the second cooler depending on the temperature of the coolant.
    Coolant temperature in the cooling system at related to the temperature of the internal combustion engine. As the cooling water has a low temperature in the cooling system, the internal combustion engine also has a low temperature. In the case of operation when the temperature of the coolant is equal to the warmer first zone of the internal combustion engine which has a temperature of an acceptablesize. The other temmstaten at dirnensionerad so it oppriar at onecoolant temperature corresponding to a temperature in the warmer first zone of the internal combustion engine cla extra cooling is required. In the case of Adana operating cases, it opensthe second thermostat and coolant are led through the second cooler, which thus has the capacity to cool the coolant to a lower temperature than in the first cooler. DarmedCoolant with a lower temperature can be led to the first zone ofthe internal combustion engine is the coolant which is led to the second zone of the internal combustion engine. In addition, more efficient cooling of the first zone of the internal combustion engine is provided, which ensures that the temperature in the first zone does not rise to an excessively high temperature level.3According to an embodiment of the present invention, the second conduit portion comprises a bypass line and that the second thermostat is adapted to lead the coolant past the second cooler via the bypass line as the coolant has a lower temperature than the control temperature of the second thermostat. Such a second management party may have oneinlet line which leads the coolant to the other cooler and an outlet line whichleads the coolant from the radiator to the internal combustion engine. The bypass line extends this case between the inlet line and the outlet line. The second thermostat is arranged in the inlet line adjacent to the bypass line where it alternatively leads the coolant through the bypass line or through the cooler depending on the coolant.temperature in the other pipe section.
    According to an embodiment of the present invention, the second conduit portion and the third conduit portion receive cooling fluid in a conduit in the cooling system so that they are coated substantially immediately downstream of the cooling water pump.

    According to an embodiment of the present invention, the third conduit portion comprises at least two cooling channels arranged in parallel which extend through other zones of the combustion engine. The cylinder head and cylinder blocks of the internal combustion engine each comprise their other zones which are located at a distance from each other. It is also in the datacase appropriate to arrange a cooling duct through the respective at a distance from each othercoated other zones in order to obtain an acceptable cooling.
    According to an embodiment of the present invention, the cooling system comprises a third thermostat which prevents cooling liquid from being conducted via the third conduit portion to the secondthe zone of the internal combustion engine when the coolant has a lower temperature than the thirdthe control temperature of the thermostat and allows cooling water to be led via the third4the line portion to the second zone of the combustion engine when the coolant has a higher temperature than the control temperature of the second thermostat. In this case, the colder second zone does not receive initial cooling after a cold start as long as the cooling liquid has a lower temperature than the control temperature of the third thermostat. Mimed canthe internal combustion engine obtains a faster heating after a cold start. The thirdthe control temperature of the thermostat defines as it is light-duty to start cooling the cooler other zones of the internal combustion engine. The first zones are cooled from the start by cooling water from the second line section.

Sadana tennostats are very cheap to obtain at the same time as they hate a lotthings function. At least one of the thermostats can have a variablecontrol temperature. During certain operating cases, it may be difficult to regulate the opening temperature of the tin states. The above-mentioned theme state can in some cases be provided with an electric heating unit with which the control temperature of the wax body can be adjusted.
    According to an embodiment of the present invention, the cooling system comprises a fourth conduit portion where the cooling liquid is used for cooling a component or a medium in the vehicle.

The internal combustion engine 1 can be a diesel electric motor and the vehicle a heavy vehicle.
    The internal combustion engine 1 comprises an exhaust line 3 which is provided with a turbine 4 ata turbocharger. A return line 5 for exhaust gas recirculation returns a part of the exhaust gases from the exhaust line 3 to the internal combustion engine I. The return line 5 comprises an EGR valve 7 with which the exhaust gas flow in the return line 5 is regulated and an EGR cooler 6 cools the recirculating exhaust gases. Vehicle 2 comprises oneair line 8 which leads I.uft to the internal combustion engine 1. A compressor 9 sucks in andcompresses the air in the air cooler 8. The compressed air is led to a charge air cooler 11 which is arranged at a front portion of the vehicle 2. A cooling fluid 10 sucks a cooling air stream of ambient air through the charge air cooler 11. After the charge air has cooled in the charge air cooler 11 it is mixed recirculating exhaust gases inthe return line 5, after which the mixture is led to the cylinders 12 of the combustion engine.
    The internal combustion engine 1 is cooled by a cooling system with a circulating cooling box. The coolant is circulated in the cooling system by means of a coolant pump 13. The coolant pump 13 can be driven in a conventional manner by the internal combustion engine 1 withan appropriate transmission not shown. The cooling system comprises an inlet line 13a whichleads the coolant to the coolant pump 13 and an outlet line 13b which receives coolant from the coolant pump 13. The cooling system comprises an expansion tank 14 for filling coolant in the cooling system as well as maintaining pressure in the system when the coolant becomes vain and expands. The expansion tank 14 dr associated withthe inlet line 13a of the coolant pump via a so-called static line 14a. This creates arequired pressure in the inlet line 13a in connection with the suction side of the coolant pump 136said that cavitation is prevented. The cooling system comprises a first thermostat 15 which regulates the cooling water flow through a first conduit portion 19 of the cooling system, a second thermostat 16 which regulates the cooling water flow through a second conduit portion 20 of the cooling system and a third thermostat 17 which regulates the cooling water flow through a third conduit portion 21in the cooling system. Teirnostatema are tried advantage of the type that contains a wax bodywhich is phase converted at the control temperature. Such thermostats are very cheap to procure while at the same time they have a range of things to do. They can also be equipped with an electric heating unit with which the control temperature can be controlled during differentThe first thermostat 15 receives coolant in a return line 18 from the internal combustion engine 1. The first thermostat 15 opens when the temperature of the coolant in the return line 18 exceeds the control temperature of the first thermostat 15. When the coolant in the return line 18 has a lower temperature than the firstthe control temperature Ti said, it leads the coolant to the coolant pumpInlet line 13a without cooling When the cooling liquid in the return line 18 has a higher temperature than the first control temperature Ti, the first thermostat 15 opens and the cooling liquid is led through the first line circuit 19. The first line circuit comprises an inlet line 19a which receives the cooling water from the return line 18 and leadsit to a first radiator 19b which is arranged at the front part of the vehicle in a positiondownstream of the charge air cooler 11 with respect to the direction of the cooling air stream through the charge air cooler 11. The cooling liquid in the first cooler 19b is cooled in this case by the same air flow as first passed through the charge air cooler 11. The air flowing through the first cooler 19b has a higher temperature. theambient air. The first conduit portion 19 includes an outlet conduit 19c whichleads the coolant from the first cooler 19b to the inlet line 13a of the coolant pump.
    The second thermostat 16 is arranged in a second conduit portion 20. The secondthe conduit portion 20 includes an inlet conduit 20a which receives cooling water frailthe coolant pump outlet line 13b. The inlet line 20a at at an opposite spiritconnected to a second cooler 20b. The second cooler 20b is arranged at the front part of the vehicle in a position at the level of the charge air cooler 11. It may alternatively be arranged in front of the charge air cooler 11. The cooling liquid is also cooled in this case by a cooling air stream which is passed through the second cooler 20b. aspassed through the second cooler 20b, however, has the ambient temperature and thusa lower temperature than the air passed through the first cooler 19b. The other7the conduit portion 20 includes an outlet conduit 20c which directs the coolant from the second cooler 20b to two parallel cooling channels 20d which extend through first zones 1a of the internal combustion engine which requires very good cooling. The first zones 1a form the areas of the internal combustion engine cylinder block and cylinder headwhich receives a high temperature during operation. The second thermostat 16 is providedinlet line 20a. The second thermostat has a second control temperature T2. When the cooling liquid in the inlet line 20a has a lower temperature than the second control temperature T2 sd, the second thermostat 16 conducts cooling liquid, via a bypass line 20e, from the inlet line 20a to the outlet line 20c without cooling inthe second cooler 20b. When the cooling box in the inlet line 20a has a higher temperatureat the second control temperature T2, the second thermostat 16 conducts cooling liquid to the second cooler 20b for cooling before it is passed on to the cooling channels 20d which extend through the combustion engine 1.
    The third conduit portion 21 includes an inlet conduit 21a which conducts cooling water frailthe outlet line 13b of the cooling water pump to the third thermostat 21. The third line part 21 comprises two parallel outlet lines 21b which conduct coolant from the third thermostat 17 when it opens to two parallel arranged cooling channels 21c which extend through a respective second zone 1b of the combustion engine. Theother zones 1b include the areas of the internal combustion engine cylinder blocks andcylinder heads which do not receive the same high temperature during operation as in the first zones 1a. The third thermostat 17 senses the temperature of the cooling water tank in the outlet line 13b of a cooling water pump. The third thermostat 17 opens cid the coolant has a higher temperature a third control temperature T3. The cooling systemalso includes a fourth lead circuit 22 which receives cooling velocitiesthe coolant pump outlet line 13b. the line circuit 22 comprises an inlet line 22a which receives cooling water and leads it to the EGR cooler 6. The fourth line circuit 22 comprises a return line 22b which leads the cooling water from the EGR cooler 6 to the inlet line 13a of the cooling water pump.
    After a cold start of the internal combustion engine 1, the coolant pump 13 starts the circulation of coolant in the cooling system. The cooling water initially has the ambient temperature which in winter can be very low. The inlet line 20a of the second line circuit 20 continuously receives cooling liquid from the outlet line 13b of the coolant pump. The other onethe thermostat 16 senses the temperature of the cooling water tank in the inlet line 20a. The cooling waterhas at least initially a lower temperature than that of the other thermostat8control temperature T2. The second thermostat 16 leads the clamed cooling liquid, via the bypass line 20e, to the outlet line 20c without cooling in the second cooler 20b. The coolant is then passed through the cooling channels 20d which stack through the first zones 1a of the internal combustion engine. The cooling fluid provides a cooling ofcylinder blocks and cylinder heads in the first zones. After the coolant passesthrough the combustion engine 1 it is wound up in the return line 18 and led towards the first thermostat 15 which controls the cooling water flow in the part of the first line portion 19. The third thermostat 17 senses the temperature of the cooling water in the outlet line 13b of the cooling water purge. The cooling water has atrninstone initially after a cold start a storagetemperature at the control temperature T3 of the third thermostat. Thus, it preventsthe third thermostat 17 to cool water is led through the cooling channels 2 lb which protrude through one of the second zones 1b of the internal combustion engine. Thus, at this stage, no cooling of the other zones 1b of the combustion engine 1 takes place. Thus, the combustion engine 1 obtains a faster recovery.
    The return line 18 receives coolant circulating through the cooling channels 20d via the second line circuit 20. The first thermostat 15 senses the temperature of the coolant in the return line 18. At this stage the coolant has a clearly lower temperature than the control temperature Ti of the first tin state 15. The first thermostat 15 thus leadsthe coolant to the coolant pump inlet line 13a without cooling in the first cooler19b. The fourth line circuit 22 continuously receives coolant from the outlet line 13b of the coolant pump. This coolant is led to the EGR cooler 6 where it cools the recirculating exhaust gases in the return line 5. The coolant is then led to the coolant pump inlet line 13a for renewed circulation in the cooling system. Duringthe above-mentioned initial stage after a cold start is accustomed to the coolant fromthe first zones 1a of the internal combustion engine 1a and the recirculating exhaust gases in the EGR cooler 6. The coolant does not provide cooling in either the first cooler 19b or the second cooler 20b. The cooling fluid in the cooling system obtains & armed a rapidly rising temperature.
    Relatively soon after a cold start, the temperature of the coolant reaches the control temperature T3 of the third tettuostat 17. The third thermostat 17 opens and a cooling water flood is obtained through the inlet line 21a. The third thermostat 17 now leads the cooling water, via the two. the outlet lines 21b, to the respective cooling channels 21c which stackthrough the other zones of the internal combustion engine lb. The cooling fluid in the other circuithowever, inlet line 20a still has a lower temperature than that of the other tin state916 control temperature 12. The second thermostat thus also leads in the data stage cooling water, via the bypass line 20e, to the outlet line 20c without cooling in the second cooler 20b. The coolant is then passed through the cooling channels 20d which extend through the first zones 1a of the internal combustion engine. The cold that passes throughthe cooling ducts 20d, 21c of the internal combustion engine are collected in the return line 18 and led towardsthe first thermostat 15. The first thermostat 15 senses the temperature of the cooling water tank in the return line 18.
    Even at this stage, the coolant has a lower temperature than that of the first ternostatcontrol temperature T1. The first thermostat 15 then leads the cooling liquid tothe coolant pump inlet line 13a without cooling in the first cooler 19b. Coolant circulation in the fourth conductor circuit 22 is unchanged. During this stage, a cooling of the combustion engine's other zones 1 is added. The cooling liquid is thus supplied with heat energy from the combustion engine's first layer and otherzones lb and from the recirculating exhaust gases in the EGR cooler 6. The cooling vesselprovides no cooling in the cooling system and the coolant temperature continues to rise.
    During continued operation of the vehicle 2, the coolant is heated, said the smaningorn up to onetemperature which is higher than the control temperature Ti of the first teiutostan 15. Thethe first thermostat 15 opens and leads coolant through the first line circuit 19. The coolant is led, via the inlet line 19a, to the cooler 19b where the coolant is cooled by air forced through the cooler 19b by means of the cooling surface 10 and the vehicle wind speed. The coolant is then led, via the outlet line I 9e, to the coolant pumpinlet line 13a for renewed circulation in the cooling system. At this stage providesthe coolant thus a cooling in the cooler 19. The function of the cooler 19 is to cool the coolant so that with the aid of the first thermostat 15 it can give the coolant a stable operating temperature at which the combustion engine 1 obtains optimum properties. The cooling effect that the cooling liquid receives in the cooler corresponds to essentially has the heating effectwhich the coolant is supplied when it is heated by the internal combustion engine and the recirculating onesthe exhaust gases in the EGR radiator 6.
    However, the load of the internal combustion engine varies during operation and clamed the heat output to be cooled in the first radiator 19b. In the event of an operation in your internal combustion engine1 is loaded hard, the first cooler 19b did not always have the capacity to cool it offheat effect that the coolant absorbs when it cools the internal combustion engine 1 and theyrecirculating the exhaust gases in the EGR cooler 6. As a result, the coolant temperature of the return line 18 rises to a higher level. at the control temperature Ti of the first thermostat. Since the first radiator 19b has the capacity to maintain the temperature of the coolant at the desired operating temperature, the second opensthe tennostaten 16. The second thermostat 16 liar a control temperature T3 asdefines when the temperature of the coolant after cooling in the first cooler 19b is too high. D. this occurs, the second thermostat 16 leads coolant in the second conduit portion 20 to the second cooler 20b. Mimed leads coolant already cooled in the first cooler 19b is cooled in the second cooler 20b In a second stage of tuft withambient temperature. It can be armed to maintain a lower temperature than the cooling waterwhich is led through the third line circuit 21 and through the second zones 1 of the combustion notor. This relatively cold cooling vessel is led from the second cooler 20b, via the outlet line 20c, to the cooling channels 20d which extend through the first zones 1a 1a of the combustion engine. The first zones thus provide oneefficient cooling. During this stage, all the cooling liquid in the first cooler is thus cooled19b. The part of the coolant which is passed through the second conduit portion also contains a cooling in a second stage in the second cooler 20b to a lower temperature than the coolant which is only cooled in the first cooler 19b, D. also the second cooler 20b is used for cooling of cooling water provides the cooling system with a range of cooling capacity.
    At the same time, the extra supplied cooling effect can be applied to the areas where the coolingNamely, in the hot first zones 1a of the internal combustion engine 1 is required the risk that the temperature in the first zones 1a of the internal combustion engine I becomes too high if the internal combustion engine 1 is loaded very hard for a long period that clamed is substantially eliminated. An additional advantage of the cooling system is that it onlya coolant pump is required to circulate the coolant in all conduit portions 19, 20,21, 22 of the cooling system. This can be done by the second line circuit 20, the third line circuit 21 and the floating line circuit 22 receiving cooling water from the outlet line 13b of the cooling water pump in I inlet lines 20a, 21a, 22a arranged in parallel. An additional advantage of the cooling system is that it has a very simple control.
    The thermostats 15, 16 and 17 provide a simple and efficient control ofthe cooling system. Thermostats are components that can be purchased at a very low cost.
    The invention is in no way limited to the embodiment described hereinthe drawing but can be varied freely within the scope of the claims.11
