Definitions
- a plurality of partial circuits comprising coolant circuit of an internal combustion engine for a motor vehicle with a device for operating such a coolant circuit, in particular for controlling the coolant flow in the individual subcircuits.
- Such coolant circuits are preferably used for the thermal management of an internal combustion engine, wherein the coolant flow between the sub-circuits of the coolant circuit is distributed by a device for operating the coolant circuit such that adjusts an optimum operating temperature of the internal combustion engine as quickly as possible.
- DE 602 09 019 T2 shows a control valve for a cooling circuit of an internal combustion engine, wherein the circuit is traversed by a coolant and a first branch with a radiator of the engine, a second branch forming a branch line of the radiator, and one or more third branches with each having at least one hot air generator for heating the passenger compartment.
- the control valve is formed as a body having a fluid inlet, a second branch connected to the first output, a second branch connected to the first branch and at least one second branch connected to the third branch, wherein a rotatably disposed within the body regulating member of the selective Control of the outputs is used.
- the regulating member can also assume a position in which no output is opened.
- a disadvantage of such a control valve is the rigidly predetermined sequence of possible positions.
- frequent position changes are necessary, which require just as frequent rotation of Regulierorgans.
- the fact that the control valve realizes many functions with only one Regulierorgan a complex structure of the control valve with a variety of components is necessary, which brings difficulties in wear and tightness with it.
- DE 103 06 094 A1 shows an internal combustion engine cooling system for a vehicle having a coolant pump, an engine circuit for conducting the coolant through the engine, a radiator circuit for conducting the coolant through the radiator, a bypass circuit for returning the coolant to the engine circuit without flowing through the radiator circuit, and a heater circuit for conducting the coolant through the heater core.
- a rotary valve is described with a valve body having an inlet port and a plurality of outlet ports, wherein the outlet ports a radiator port for conducting the coolant in a radiator circuit, a bypass port for conducting the coolant in a bypass circuit and a heater port to Conducting the coolant in a Schuerniklauf include.
- the valve body further includes a rotatably mounted Stromverzweiger with a plurality of fluid passages, which depend on a rotational position of Power splitter for preset flow paths between the inlet port and the outlet ports.
- the preset flow paths thereby comprise a first mode of operation for distributing the coolant to the radiator connection and to the heater connection while blocking the bypass connection, a second mode of distributing the coolant to the bypass connection while simultaneously blocking the coolant from the radiator connection and the heater connection, a third mode of operation Distributing the coolant to the heater port while simultaneously blocking the coolant from the radiator port and the bypass port, and a fourth mode of distributing the coolant to the radiator port and the bypass port while blocking the coolant from the heater port.
- a disadvantage of such a combustion engine cooling system is due to the structure of the rotary valve limiting the switchable circuits.
- the inclusion of additional circuits would inevitably lead to a deterioration in the control of the circuits in detail.
- the coolant temperature can not be adjusted with sufficient accuracy and speed to the desired value, which leads to a poorer achievement of the operating temperature of the internal combustion engine.
- the object of the present invention is therefore to provide a coolant circuit which, with a simple construction, permits extensive control of a multiplicity of partial circuits of the coolant circuit.
- a coolant circuit in particular a multi-circuit having coolant circuit of an internal combustion engine with a main cooling circuit and a heating circuit, has a arranged on a turntable coolant pump, wherein the turntable with a rotary valve housing a plurality of flowed through by coolant connections, and a first and at least a second rotatably mounted in the rotary valve housing rotary valve, each having at least one flow path forming rotary valve flow-through, the connections brought by a rotational movement of the respective rotary valve in at least partially overlap with the rotary valve flow openings and wherein a first branch of the main cooling circuit leading from the internal combustion engine to a main radiator port of the first rotary valve is switchable by the first rotary valve, and wherein a second branch of the main cooling circuit leading from an outlet of the coolant supply pump to the internal combustion engine is switchable by the second rotary valve
- the headers of the individual subcircuits are connected to the first rotary valve, which is fluidically connected to a suction port of the coolant pump.
- the rotary valve flow-through openings of the first rotary valve can be brought into a continuously variable overlap with the corresponding connections of the rotary valve housing and thus switch different flow paths with varying flow rates.
- the control of the return flow of the coolant from the coolant supply pump is realized in a second branch of the main cooling circuit by the second rotary valve.
- the second rotary valve can be very easily formed as a rotary body with a through hole as a rotary valve flow-through, which corresponds to the two opposite ports of the rotary valve housing.
- the heating circuit branches off upstream of the second rotary valve from the second branch of the main cooling circuit and leads coolant via a heating heat exchanger to the internal combustion engine.
- the heating circuit branches off in front of the second rotary valve, this is constantly acted upon regardless of the position of the second rotary valve with heated coolant from the coolant pump, which contributes to a rapid heating of the passenger compartment in the motor vehicle through the heater core.
- a bypass branches off from the first branch of the main cooling circuit downstream of the internal combustion engine to a bypass port of the first rotary valve, wherein the first rotary valve switches the bypass.
- the bypass heated coolant flows from the internal combustion engine to the bypass port of the first rotary valve, without being cooled by the main radiator.
- an oil cooler circuit carries coolant from the engine via an oil cooler to an oil cooler port of the first rotary valve, wherein the first rotary valve switches the oil cooler circuit.
- heated coolant flows from the internal combustion engine into the oil cooler, where a heat exchange with the lubricant of the internal combustion engine takes place.
- the coolant flows to the oil cooler port of the first rotary valve, where it can be mixed with the coolant flows from the other sub-circuits.
- the second rotary valve closes the second branch of the main cooling circuit. If the coolant has a relatively low temperature below a first threshold, which is often the case after the start of the engine, the second branch of the main cooling circuit is closed by the second rotary valve, whereby no coolant from the coolant supply pump can flow back into the internal combustion engine. If the heating circuit is also closed, the coolant heats up particularly quickly in the internal combustion engine, since no circulation takes place in the coolant circuit.
- the first rotary valve closes the oil cooler port and the main radiator port while the bypass port is opened. Thus, all coolers located in the coolant circuit are not flowed through with coolant during this phase.
- the first rotary valve opens the bypass and the second rotary valve opens and closes the second branch of the main cooling circuit at intervals.
- the second rotary valve is rotated in such a way that it passes coolant through at intervals. This results in a relatively low coolant flow with a weak circulation of the coolant within the internal combustion engine, which leads to a more homogeneous temperature distribution at the individual components of the internal combustion engine at a further rapid heating rate of the coolant.
- the first rotary valve closes the oil cooler port and the main radiator port while the bypass port is opened.
- the first rotary valve opens the bypass and the oil cooler circuit and the second rotary valve opens the second branch of the main cooling circuit.
- the second rotary valve is permanently opened.
- the first rotary valve opens the oil cooler connection in addition to the bypass connection, but preferably still keeps the main cooler connection closed.
- the first rotary valve opens the oil cooler circuit and intermittently opens and closes the first branch of the main cooling circuit and the bypass to achieve a coolant temperature set point and the second rotary valve opens the second branch of the main cooling circuit.
- the coolant temperature rises above the third threshold value, but is still below a limit value, the coolant has reached approximately its intended setpoint temperature, whereupon the first rotary valve alternately alternately opens and closes the bypass connection and the main radiator connection.
- the coolant temperature in the first branch of the main cooling circuit is determined downstream of the internal combustion engine.
- determining the coolant temperature in the first branch of the main cooling circuit at the coolant outlet of the internal combustion engine can be relatively simple be closed on the present in the internal combustion engine coolant temperature.
- the first rotary valve in a coasting operation after the engine is shut down, opens the first branch of the main cooling circuit and closes the bypass, and the second rotary valve closes the second branch of the main cooling circuit. Since in after-running operation after switching off the internal combustion engine by the lack of wind usually no sufficient heat dissipation takes place on the radiators more, the second rotary valve closes the second branch of the main cooling circuit, while the first rotary valve opens the main radiator connection and the bypass port, and the oil cooler connection closes. As a result, the coolant from the internal combustion engine can flow back into the internal combustion engine via the main radiator, the turntable and the heating heat exchanger. By flowing through both the main radiator and the heating heat exchanger, the cooling surface increases, which contributes to improved heat dissipation.
- a heating feed pump arranged in the heating circuit circulates the coolant. Since from a belt-driven coolant delivery pump after switching off the engine no more capacity can be retrieved, the circulation takes place during the follow-up operation by an electrically driven heating pump in the heating circuit.
- a shut-off valve is arranged in the heating circuit, in particular upstream of the heating pump, which is open in the wake mode.
- the inflow of coolant to the heater core can be interrupted when no heating power for the passenger compartment of the motor vehicle is required.
- the first rotary valve is arranged coaxially to the suction mouth of the coolant delivery pump and the second rotary valve is arranged axially parallel to the suction mouth of the coolant delivery pump.
- the first rotary valve is arranged with its axis of rotation coaxial with the axis of rotation of the suction mouth of the coolant delivery pump, the coolant delivery pump can easily suck the coolant from the interior of the first rotary valve.
- the second rotary valve is arranged with its axis of rotation axially parallel to the axis of rotation of the suction mouth of the coolant pump with a fluidic connection to the outlet of the coolant pump, so that the coolant pump can promote the sucked from the first rotary valve coolant to the second rotary valve.
- Particularly advantageous is an arrangement of the second rotary valve in a radial peripheral region of the coolant supply pump. Such an arrangement provides advantages in terms of space utilization.
- the first rotary valve is driven by an actuator and the second rotary valve is operatively connected via at least one angular range with the first rotary valve, wherein the second rotary valve is driven by the first rotary valve.
- the first rotary valve is provided with an actuator, costs and space can be saved.
- the drive of the second rotary valve takes place indirectly by a toothing with the first rotary valve, wherein the first and the second rotary valve mesh with each other only in an angular range.
- the angular range of attacks is limited, where the second rotary valve comes to rest, if it is not operatively connected to the first rotary valve. If there is no more active connection between the first and the second rotary valve, the second rotary valve is located on one of the stops on the outer edge of the angle rich, while the first rotary valve outside the angle range can continue to turn.
