Definitions

  • Modern cars have a complex cooling system with several "partial cooling circuits" on. Some of these subcooling circuits are dependent on the operating condition of the vehicle or its vehicle components, e.g. the engine and the transmission, optionally provided for cooling or for heating or preheating of individual components. To control such a complex cooling system, a variety of control or regulating organs are required.
  • the object of the invention is to provide a cooling system with a plurality of controllable cooling liquid-carrying partial cooling circuits, which is constructed compact and inexpensive.
  • the starting point of the invention is a vehicle having a fluid control system for cooling fluid, which has a plurality of coolant fluid-carrying fluid circuits, their volume flows are controlled or regulated by control or regulating organs. By controlling or regulating the volume flows of the individual fluid circuits, the heat output transported by the individual fluid circuits can be regulated.
  • the term "fluid circuits" is to be understood here extremely broad. Generally speaking, this refers to fluid circuits designed to transport heat. Depending on the type of fluid circuit and depending on the operating state of the vehicle or its vehicle components, these fluid circuits are used for cooling, ie for removing heat or for preheating or heating vehicle components.
  • the essence of the invention consists in that all the control or regulating elements present in the vehicle, which are provided for controlling or regulating the volume flows of the coolant-carrying fluid circuits of the fluid control system, are structurally combined or integrated into a common control / regulating device.
  • the number of control elements and the number of cable and line strands and holding devices can be reduced compared with conventional cooling systems. Overall, therefore, the complexity of the fluid control system can be reduced. Furthermore, the filling and venting of the fluid control system is simplified. Furthermore, a modular design, a standardization of individual components as well as a reduction of the number of interfaces is made possible.
  • the controller is modularly composed of a plurality of individual control modules.
  • Each of these control modules is associated with at least one or more of the controllable fluid circuits.
  • the individual control / regulating modules may each have a housing, which may then be connected to the common control / regulating device.
  • the fluid control system can have several different fluid circuits.
  • a fluid circuit may be provided which has a heat accumulator which is provided to store after stopping the vehicle, a portion of the heat contained in the cooling fluid of the fluid control system, then at restarts the vehicle, the stored heat over the fluid control system in the short term supply to other vehicle systems.
  • a heat accumulator depending on the operating strategy, e.g. the engine oil circuit, the transmission oil circuit or the heating circuit provided for heating the passenger compartment are preheated. Preheating the engine and / or transmission oil circuits reduces exhaust emissions during warm-up of the vehicle and reduces wear on the engine and transmission.
  • a fluid circuit is further provided, the cooling channels extending exclusively through the cylinder head of the engine and allow depending on the operating condition of the engine, a preheating and / or cooling of the cylinder head portion of the engine.
  • crankcase can be preheated and / or cooled independently of the cylinder head.
  • split cooling Such independent preheating or cooling of the cylinder head and crankcase is also referred to as "split cooling".
  • a fluid circuit may be provided which has a heat exchanger, via which the cooling fluid-carrying fluid circuit is thermally coupled to a motor oil circuit of the vehicle engine. about This fluid circuit can then be selectively preheated or cooled, the engine oil of the vehicle engine.
  • Another aspect of the invention is to provide a fluid circuit having a coolant / heater core.
  • Thisdestattkeits- / heating heat exchanger allows a thermal coupling of this fluid circuit with a heater which is provided for heating the passenger compartment.
  • a fluid circuit with a coolant / gear oil heat exchanger can be provided, via which the gear oil can be preheated or cooled in a targeted manner.
  • FIG. 1 shows a cooling system 1 of a vehicle.
  • the cooling system 1 has a plurality of "partial circuits" which are used as a function of the operating state of the vehicle, in particular of the engine 2, for preheating or for cooling individual vehicle components.
  • the individual subcircuits are controlled or regulated by a central control / regulating device 3.
  • a central control / regulation unit 3 individual control circuits associated with the respective subcircuits are structurally combined.
  • the individual control / regulating modules can be combined in a common housing of the control / regulating device 3.
  • the Control / regulating device 3, however, can also be modular. That is, the housing of the individual control / regulating modules can be connected to the control / regulating device 3 with each other.
  • a central element of the cooling system 1 is the main water cooler 4.
  • the main water cooler 4 has an inlet 5 and an outlet 6. Via the input 5, hot water coming from the engine 2 is supplied to the main water cooler 4. After the cooling water has been cooled in the main water cooler 4, it flows via the outlet 6 to an input 7 of the control / regulation device 3. In the control / regulation device 3, the cooled cooling water is distributed to the individual partial circuits.
  • a first partial circuit has a heat accumulator 8.
  • heat can be stored from the cooling water after parking the vehicle.
  • the heat stored in the heat accumulator 8 can be used for faster heating of individual vehicle components, such as e.g. the cylinder head, the crankcase or the engine oil or the transmission oil are used.
  • Another partial circuit comprising cooling channels, which are provided in the crankcase 9 of the engine 2, is supplied via an output 10 of the control / regulating device 3 with cooling water.
  • the crankcase 9 of the engine 2 can be preheated in a targeted manner when the engine is cold or cooled when the engine is hot.
  • Another partial circuit comprising cooling channels, which are provided in the cylinder head 11 of the engine 2, is supplied with cooling water from an outlet 12 of the control device 3.
  • the cylinder head 11 of the engine 2 can be preheated targeted or cooled when the engine is warm engine.
  • Another partial circuit has a cooling water / engine oil heat exchanger 13.
  • the cooling water / engine oil heat exchanger 13 is supplied via an output 14 of the control / regulating device with cooling water.
  • the engine oil can be preheated or cooled specifically when the engine is warm.
  • a partial circuit is provided, which is supplied via an output 15 with cooling water from the control / regulation device 3. From the outlet 15 cooling water, which was previously cooled in the main water cooler 4, flows to an input 16 of a "low-temperature cooler" in which the already pre-cooled cooling water is further cooled. From an outlet 18 of the low temperature radiator 17, the cooling water then flows into a cooling water / transmission oil heat exchanger 19 and thence back into the controller 3.
  • the transmission oil of a transmission of the vehicle can be deliberately preheated or reheated or cooled via this partial circuit.
  • Such cooling water / transmission oil heat exchangers can be used in particular in automatic transmissions, dual-clutch transmissions or automated manual transmissions.
  • a partial circuit with a cooling water / heating heat exchanger 20 is also provided, which is supplied from an outlet 21 of the control / regulation device 3 with cooling water. Via the outlet 21, warm or hot cooling water is supplied to the cooling water / heating heat exchanger. In the cooling water / heating heat exchanger 20, heat is then transferred to the fresh air introduced into the passenger compartment of the vehicle. From the cooling water / heating heat exchanger 20, the cooled cooling water then flows via a line 22 back into the control / regulating device 3.
  • a compensating vessel 23 is mentioned, which allows expansion of the cooling water flowing in the cooling system 1.
  • all the control or regulating elements required for the control / regulation of the individual partial circuits can be structurally combined in the control device 3.
  • no control or regulating organs are required, which are arranged outside the control / regulating device in the individual controllable subcircuits of the cooling system.
  • the coolant pump 24 of the cooling system 1 can be integrated.
  • FIG. 1 shows a cooling system with "inlet regulation".
  • An entry regulation is characterized in that the control / regulating device 3 is supplied via the input 7 directly coolant, which was previously cooled by the main water cooler 4.
  • the control / regulation device 3 of FIG. 1 then controls or regulates the volume flows of the previously cooled coolant to be supplied to the individual subcircuits.
  • FIG. 2 shows a cooling system 1, which is constructed very similar to the cooling system 1 shown in FIG.
  • the main difference with respect to the cooling system of Figure 1 is that in the embodiment of Figure 2, a "exit control" is provided.
  • the controller becomes hot from the engine, i. from the cylinder head part cycle, the Kurbelvüellengephinuseteilnikank and coming from the engine oil subcircuit cooling water via inputs 25, 26, 27, respectively.
  • the hot coolant is then fed to the inlet 5 of the main water cooler 4.
  • the cooled coolant flows to the coolant pump 24, which pumps it into the individual sub-circuits of the cooling system 1.
