Summary of the invention
The objective of the invention is to propose a kind of cooling system that is used for vehicle, it can also realize the good cooling of other medium and member in the vehicle except the cooling combustion motor, or even to be in the situation under the heavy duty at cooling system also be like this.
The cooling system of the type that described purpose utilization is mentioned in foreword and realize that described cooling system is characterised in that feature pointed in the characteristic of claim 1.Cooling system comprises first pipe-loop that is suitable for the cooling combustion motor and second pipe-loop that comprises at least one heat exchanger thus, and the another kind of medium in described heat exchanger in the vehicle is predefined for the coolant cools that receives by from first pipe-loop.In cooling system is not in situation under the heavy duty, the freezing mixture in first pipe-loop will be under the temperature, so that it can be received and be used to the medium in the cooling heat exchanger in second pipe-loop under the situation that does not have extra cooling.In this case, freezing mixture mainly is conducted through bypass line, and passes through additional heat sink before it arrives the heat exchanger that cools off described medium.Additional heat sink is not used to cool off freezing mixture in this case thus.Use bypass line to guarantee not to be cooled too much at the freezing mixture that cooling system is not in the heavy duty cooling system of following time, described cooling can cause the operating temperature that combustion engine is low excessively too much.In cooling system is not in situation under the heavy duty, the freezing mixture that guides to second pipe-loop from first pipe-loop will be under the too high temperature, thereby can not be used to the medium in the cooling heat exchanger under the situation that does not have extra cooling.In this case, freezing mixture mainly is conducted through additional heat sink.Freezing mixture has had the enough low temperature that is used for cooling medium as required when it arrives heat exchanger thus.
According to a preferred embodiment of the present invention, valve system is disposed in the bypass line.Described valve system can be placed in open position and closed position, and it allows freezing mixture to be conducted through bypass line at described open position, and it stops freezing mixture to be conducted through bypass line in described closed position.When valve system was in the closed position, all freezing mixtures were conducted through the pipeline in parallel that is provided with additional heat sink.Do not have valve system or be blocked if having the pipeline self of additional heat sink, then when the valve system in the bypass line is opened, also have ANALYSIS OF COOLANT FLOW by having the pipeline of additional heat sink with certain other method.In order to distribute freezing mixture stream between pipeline, can being constituted as of bypass line makes described freezing mixture with than being conducted through described bypass line by the low flow resistance of pipeline that has additional heat sink.Can realize less suitably ANALYSIS OF COOLANT FLOW thus by additional heat sink.This can be radiator perforate (venting), and reduce radiator thermal fatigue risk and when cold ambient temperature is leading, in radiator, form the risk of ice.
According to another preferred embodiment of the present invention, second pipe-loop comprises the temperature transducer of the temperature that is suitable for detecting described medium, and described control unit is suitable for receiving information and controlling described valve system from described sensor being higher than the highest temperature most at least freezing mixture of following time of accepting temperature and being conducted through the pipeline that has additional heat sink so that be at described medium.The temperature transducer that utilization is positioned properly, in case control unit can be when medium reaches excessive temperature just immediately control valve mechanism so that most at least freezing mixture is conducted through additional heat sink.The described extra cooling of freezing mixture makes its more effectively medium in the cooling heat exchanger.Described more effective cooling has the effect that reduces medium temperature.Be lower than the highest temperature of accepting the predetermined number of degrees with respect of temperature in case medium reaches, control unit is just opened valve system so that freezing mixture is conducted through bypass line once more.Alternatively, second pipe-loop can comprise the temperature transducer that is suitable for detecting coolant temperature, and control unit can be suitable for receiving information and control valve mechanism from described sensor and be higher than the highest temperature most at least freezing mixture of following time of accepting temperature and be conducted through the pipeline that has additional heat sink so that be at freezing mixture.Under the sort of situation, control unit is thus by means of coolant temperature control valve mechanism.When the freezing mixture that receives in second cooling circuit is too warm during with the medium in can not cooling heat exchanger, be conducted through additional heat sink before its medium in allowing cooling heat exchanger.If freezing mixture is not too hot, then it is directed to heat exchanger so that cooling medium via valve system under the situation that does not have extra cooling.
According to another preferred embodiment of the present invention, second pipe-loop comprises at least two heat exchangers that are used to cool off respective media.In heavy vehicle, need to cool off a large amount of media especially.Such medium can be refrigeration agent, the machine oil in the servo-system, fuel and the hydraulic oil in pressurized air, EGR gas, gearbox machine oil, the air-conditioning system.Described heat exchanger can be arranged in parallel in second pipe-loop.This makes the freezing mixture that is in roughly the same temperature can be used for cooling off the medium of respective heat exchanger.Alternatively, described heat exchanger can be in second pipe-loop tandem arrangement.The most effective cooling of the heat exchanger medium that this acquisition freezing mixture at first flows through.Heat exchanger advantageously is a contraflow heat exchanger.This makes medium can be cooled to the temperature near the inlet temperature of freezing mixture in the heat exchanger.
According to another preferred embodiment of the present invention, second pipe-loop receives freezing mixture and makes freezing mixture return described first pipe-loop in the second place from described first pipe-loop at the primary importance place, and freezing mixture compares at described primary importance place in the described second place everywhere under higher pressure.Utilize this connection of second pipe-loop to the first pipe-loop, the coolant pump in first pipe-loop can also be used for making freezing mixture to circulate in second pipe-loop.In order to obtain to be used to guarantee the pressure difference by the continuous ANALYSIS OF COOLANT FLOW of second pipe-loop, second pipe-loop needs relatively on the pressure side receiving freezing mixture and near the suction side of coolant pump freezing mixture being returned relatively near coolant pump.
According to another preferred embodiment of the present invention, second pipe-loop comprises fan, and control unit is suitable for starting fan so that the cooling air flow by additional heat sink to be provided when medium in heat exchanger has extra cooling requirement.The cooling effect of the freezing mixture in the additional heat sink is enhanced thus.Control unit preferably starts the motor of drive fan when freezing mixture is conducted through additional heat sink.Additional heat sink is advantageously located at the peripheral surface in the vehicle, thereby it makes the air flows that is in ambient temperature when fan is activated by it.Freezing mixture can be accepted very effective cooling thus in additional heat sink.

Fig. 1 schematically shows the traffic tool 1 that driven by supercharged combustion engine 2, and it can be a diesel engine.The traffic tool 1 are heavy vehicle advantageously.Combustion engine 2 is had the cooling system cooling of circulating coolant.Coolant pump 3 is suitable for making circulate coolant to pass through cooling system.Cooling system comprises first pipe-loop 4 and second pipe-loop 5.First pipe-loop 4 comprises schematically illustrated cooling tube 4a, and it extends through combustion engine 2 so that described combustion engine 2 bears required cooling.After freezing mixture had cooled off combustion engine 2, it was received in pipeline 4b, and described pipeline 4b guides to thermostat 6 with freezing mixture.Thermostat 6 guides to pipeline 4c and pipeline 4d according to coolant temperature with the freezing mixture of variable amount.Pipeline 4c leads coolant back to petrolift 3 and combustion engine 2, and pipeline 4d guides to freezing mixture in the radiator 7 of the front part office that is assemblied in the traffic tool 1.Radiator fan 8 is suitable for producing the cooling air flow by radiator 7.When freezing mixture had arrived the routine work temperature, roughly all freezing mixtures were directed to radiator 7 so that be directed back via pipeline 4e being cooled before petrolift 3 and the combustion engine 2 at it.First pipe-loop 4 of cooling system has the configuration of traditional cooling system of the combustion engine 2 that is used for cooling traffic vehicle 1 thus.
Second pipe-loop 5 of cooling system comprises pipeline 5a, and it receives freezing mixture at the 4a place, position on the pressure side that is positioned near coolant pump 3 from first pipe-loop 4.Pipeline 5a is divided into two pipeline 5b in parallel, 5c continuously.The first pipeline 5b in parallel comprises extra radiator 9.Described extra radiator 9 is assemblied in the outer peripheral areas of the traffic tool 1.Described in this case outer peripheral areas is positioned at the front portion of the traffic tool 1.The radiator fan 10 that is driven by motor 11 is suitable for producing the cooling air flow by extra radiator 9.The second pipeline 5c in parallel is the bypass line that comprises valve 12.Control unit 13 is suitable for controlling motor 11 and valve 12.Pipeline 5b in parallel, 5c combine in pipeline 5d, and described pipeline 5d guides the first heat exchanger 14a and the second heat exchanger 14b with freezing mixture.In this case, freezing mixture and corresponding heat exchanger 14a, 14b are directed in parallel.Freezing mixture is predefined for the medium among cooling corresponding heat exchanger 14a, the 14b.In this case, the machine oil from the gearbox of the traffic tool is cooled in the first heat exchanger 14a.Another kind of medium is cooled in the second heat exchanger 14b, and described another kind of medium for example can be the medium or the hydraulic oil of the electric component of the refrigeration agent in pressurized air, EGR gas, the air-conditioning system, the machine oil that is used for servo-system, fuel, cooling traffic vehicle 1.In heavy vehicle 1, there are multiple medium and member to be cooled thus.Temperature transducer 15 is suitable for detecting the appropriate location temperature of gearbox machine oil everywhere.In the vehicle operating process, signal about oil temperature is measured and roughly sent constantly to temperature transducer 15 to control unit 13.After freezing mixture had cooled off medium among heat exchanger 14a, the 14b, it was directed back first pipe-loop 4 via pipeline 5e.Freezing mixture is directed back the pipeline 4e in first pipe-loop 4 at position 4e place, described position 4e at this between radiator 7 and coolant pump 3.
In the combustion engine running, coolant pump 3 make circulate coolant by first pipe-loop 4 so that combustion engine is subjected to necessary cooling.Second pipe-loop 5 is dimensioned to making it locate to be received in via pipeline 5a the freezing mixture of circuit special ratios in first pipe-loop 4 at position 4a '.The information that control unit 13 receives about the temperature of gearbox machine oil from temperature transducer 15.Control unit 13 comprises the highest stored information of accepting temperature that should not surpass about gearbox machine oil.During temperature in gearbox machine oil is in acceptable scope, control unit 13 is suitable for valve 12 is remained on open position.Control unit 13 is suitable for keeping motor 10 to be cut off simultaneously, so that fan 11 does not provide the cooling air flow by extra radiator 9.
The feasible flow resistance by bypass line 5c that is constituted as second pipeline system 5 compares by the flow resistance of the pipeline 5b that has extra radiator 9 little a lot.When valve 12 is opened, therefore the major component of coolant circulating will be conducted through bypass line 5c in second pipe-loop 5.Have only the freezing mixture of fraction will be conducted through pipeline 5b and extra radiator 9.Even extra radiator 9 does not need to be used for cooling off the freezing mixture of second pipe-loop 5 in this case, yet for a plurality of reasons, it also is favourable making the freezing mixture of fraction pass extra radiator 9.This little freezing mixture stream makes and can be 9 perforates of extra radiator, guarantee that thus extra radiator 9 remains on a temperature, so that the risk of thermal fatigue reduces, and the risk that formation is iced in extra radiator 9 when cold ambient temperature is leading reduces.Can accept temperature following time when gearbox machine oil is in, be used for cooling off the medium among corresponding heat exchanger 14a, the 14b under the situation of freezing mixture any extra cooling in not having extra radiator 9.After this freezing mixture is located to be directed back first pipe-loop 4 via pipeline 5e at position 4e '.Second pipe-loop 5 thus from first pipe-loop 4 the position 4a ' on the pressure side near coolant pump 3 receive freezing mixture, and locate to lead coolant back to first pipe-loop at position 4e ' near the suction side of coolant pump 3.Described position 4a ' in first pipe-loop 4 and the pressure difference between the 4e ' guarantee that the circulation of freezing mixture by second pipe-loop 5 can be by being held with making the freezing mixture coolant pump 3 that the circuit pump is identical in first pipe-loop 4.
Can accept temperature if the temperature of gearbox machine oil rises to be higher than, then control unit 13 finds that the freezing mixture in first pipe-loop 4 is in too high temperature for cooling off gearbox machine oil in a desired manner.So control unit 13 cut-off valves 12, actuating motor 11 and fan 10 simultaneously.All freezing mixtures in second pipe-loop 5 are conducted through pipeline 5b and extra radiator 9 then, and freezing mixture bears cooling by the air that is forced through extra radiator 9 therein.Freezing mixture in second pipe-loop 5 bore before it is used for the medium of cooling heat exchanger 14a, 14b thus and effectively is cooled to the temperature that is lower than the coolant temperature in first pipe-loop 4 clearly.Because heat exchanger 14a, 14b are arranged in parallel in this case, so the medium among corresponding heat exchanger 14a, the 14b will be by being in the coolant cools of same low temperature.Cold freezing mixture provides effective cooling of the medium among corresponding heat exchanger 14a, the 14b.Effective cooling of gearbox machine oil makes that gearbox machine oil relatively promptly is cooled to and can accept temperature in heat exchanger 14a.When control unit 13 information of receiving represented that gearbox machine oil has been cooled to be lower than the temperature of the highest predetermined number of degrees with respect of accepting temperature, it opened valve 12, cuts off motor 11 and fan 10 simultaneously.Therefore the major component of freezing mixture will be conducted through bypass line 5c once more, and have only fraction to pass through pipeline 5b and extra radiator 9.
Fig. 2 shows an alternate embodiment of cooling system.In this embodiment, control unit 13 is from the information of temperature transducer 16 receptions about the temperature of the freezing mixture of reception second pipe-loop 5.Be higher than under the highest temperature of accepting temperature if freezing mixture is in, then control unit 13 finds that the medium among heat exchanger 14a, the 14b can not be by this warm required cooling of freezing mixture reception.So control unit 13 cut-off valves 12, actuating motor 11 and fan 10 simultaneously.All freezing mixtures in second pipe-loop 5 are conducted through pipeline 5b and extra radiator 9 then, and freezing mixture bears cooling by the air that is forced through extra radiator 9 therein.The freezing mixture that is directed to heat exchanger 14a, 14b in extra radiator 9 after the cooling will be in significantly lower temperature then, and therefore effective cooling of gearbox machine oil among the first heat exchanger 14a can be provided.After this pressurized air be directed to the second heat exchanger 14b, and described therein pressurized air cools off second medium.In this case, heat exchanger 14a, 14b be thus by tandem arrangement, and this is favourable when a kind of medium need be cooled to than the low temperature of another kind of medium.The extra cooling of freezing mixture makes the freezing mixture that spreads all over (running through) cooling system be in lower temperature in the extra radiator 9.When control unit 13 information of receiving represented that freezing mixture has been cooled to be lower than the temperature of the highest predetermined number of degrees with respect of accepting temperature, it found to be used to cool off described medium once more under the situation of can be in the not having extra radiator 9 not any extra cooling of freezing mixture.So control unit 13 is opened valve 12, cut off motor 11 and fan 10 simultaneously.The major component of freezing mixture will be conducted through bypass line 5c thus, and have only fraction to pass through pipeline 5b and extra radiator 9.
The present invention never is limited to the mode of execution of accompanying drawing indication, but can freely change in the scope of claims.
