Definitions
- the present invention relates to a device for cooling and / or heating a motor vehicle according to the preamble of the independent claim.
- cooling systems are therefore used in which a coolant flows through the cooling water spaces, which at least surround the cylinder and cylinder head, in order to then at least partially emit the heat to the environment via a cooler, or via a heat exchanger for the heating, for example to use a vehicle interior.
- auxiliary units In modern vehicles, various engine auxiliary units are used, which are also referred to below as units or Auxiliary units are used.
- auxiliary units can be electrical machines, such as starters or generators, or oil coolers and air conditioning compressors. In many cases it is necessary to cool such units in a manner similar to that of the internal combustion engine.
- a significantly increased efficiency of modern engines means that the amount of heat generated by the internal combustion engine, which is available for further use in the cooling and heating system of the vehicle, is increasingly restricted.
- the heat input into the cooling water which can be provided by the internal combustion engine itself, is no longer sufficient.
- the internal combustion engine and its catalytic converter do not reach the optimum working temperatures in the time available, which leads to increased fuel consumption and increased exhaust gas emissions.
- Cooling and heating circuit of the vehicle are integrated to additionally heat the cooling water in certain operating states of the internal combustion engine.
- auxiliary heaters are either operated electrically or burn fuel (chemical auxiliary heaters) in order to generate the required heat.
- These auxiliary heaters are quite expensive and also have the disadvantage that they also have to be installed in the, generally narrow, engine compartment of a motor vehicle and thus cause considerable costs.
- Power electronics that emit heat while driving are equipped with devices for liquid cooling.
- the cooling connections of these devices are connected via a closed pipe system to a pump and a heating system which can emit heat to the interior of the vehicle. This allows the Power semiconductors via the heat sink dissipated heat are supplied to the heating system.
- a main problem with the entry of the heat loss from electronic power semiconductors, for example also from starters or generators, into the cooling circuit of a vehicle is not to exceed the permissible component temperature of the semiconductor elements at high cooling water temperatures.
- a heat exchange system for a vehicle with an internal combustion engine and an electric motor is known, the engine cooling circuit of which is equipped with a mechanical water pump and the electronics cooling circuit of which is equipped with an electric water pump.
- the two cooling circuits are coupled to one another by openable or closable connecting lines so that the heat dissipated by the power electronics through the cooling water can be used to heat the cooling water and thereby to heat the passenger compartment via a heating heat exchanger.
- a heating and cooling concept for a motor vehicle is known from a special edition of the Automobiltechnische publication (ATZ) and the Motortechnische Symposium (MTZ) from May 1998, in which the water cooler of the cooling system is divided serially into a high and a low temperature section. With this split of the cooler, two different flow rates are possible.
- By inserting a separator into the radiator water box about 20% of the radiator network area in the lower area of the radiator is used to produce a low-temperature part.
- a throttled coolant flow in the low temperature range an almost twice as high temperature cooling gradient is achieved as in the upper cooler area, which due to its higher flow rate only achieves a temperature reduction of around 7 degrees Celsius in the case of cooling output.
- the claimed device according to the invention for cooling and / or heating a motor vehicle has the advantage that through the at least one bypass line and the associated bypass valve, which are assigned to at least one secondary cooler segment and which are parallel to this secondary cooler segment in the cooling and heating system of the motor vehicle are arranged, the heat dissipation in the assigned cooler segment is to be regulated as required.
- the bypass valve and the assigned bypass line make it possible to bypass the cooler if necessary.
- the full thermal output of the additional unit for example a generator or starter, can be used to accelerate the warm-up of the internal combustion engine or to increase the heating output of the system.
- At least one first unit to be cooled is connected to the cooling and heating system of the motor vehicle via a secondary cooler segment.
- the first unit to be cooled can have a " different temperature " to the engine temperature level be operated. For example, it is possible to cool a first unit with a temperature significantly lower than the engine temperature.
- At least one second unit to be cooled is connected in parallel to the internal combustion engine and / or to the main cooler segment, this unit can be cooled without the need for an additional coolant pump. In this way, it is possible that neither coolant heated water is supplied to the unit by the internal combustion engine, nor that coolant heated by the unit is supplied to the internal combustion engine.
- the second unit to be cooled that is to say an unit connected in parallel to the internal combustion engine and / or to the main cooler segment, can also be a first unit to be cooled, that is to say additionally connected to the cooling and heating system of the motor vehicle via a secondary cooler segment.
- a first and a second unit are spoken of in the following, which are not subject to any sequence, but only differentiate the manner in which an auxiliary unit is introduced into the cooling and heating circuit according to the invention of a motor vehicle.
- the volume flow and / or the temperature of the coolant pumped by at least one first and / or at least one second unit can be varied via at least one valve in the feed line of the at least one first and / or at least one second unit.
- this at least one valve can be a thermostatic valve, in particular a mixing valve.
- this at least one valve in the supply line to the at least one first and / or the at least one second unit is a regulated mixing valve. This valve allows the coolant flow to be regulated as required by a first or a second unit. In this way it is possible to load the water pump as little as possible and to minimize the pump output.
- a regulated three-way valve can be used, which distributes the volume flow provided by the water pump to the internal combustion engine and the electrical machine as required.
- Such a measure also makes it possible for the first unit to be operated at significantly lower temperatures than the internal combustion engine, specifically within a defined, second temperature range.
- the presence of such a second defined temperature range can be advantageous, for example, if the first unit is formed by a power electronics circuit, for example, assigned to a starter generator, and the second unit is such a starter generator. In this case, it is possible to operate the starter generator in a temperature range comparable to that of the internal combustion engine, while the associated one
- Power electronics circuit can be operated at a significantly lower temperature. In this way, it is possible to ensure that the components of the power electronics are not thermally destroyed or otherwise adversely affected.
- the valves located in the feed lines to the units are actuated as a function of the temperature detected by a temperature sensor.
- a control unit is part of the device and that this control unit actuates the regulable or controllable valves in accordance with a comparison value or limit value stored, for example, in the control unit itself.
- Power electronics circuit or is formed by another type of circuit, it is also possible, for example, to integrate the control and / or regulating device directly into this circuit.
- Sensor signals other than those supplied by a temperature sensor are also possible for controlling or regulating the supply lines using a control device or a corresponding control and / or regulating circuit.
- additional sensors for the pressure, the flow volume or other useful parameters of the coolant can be present in the device according to the invention.
- the delivery rate of the coolant pump can be regulated or controlled independently of the speed of the internal combustion engine.
- the use of an electrical coolant pump is possible.
- the delivery rate of the coolant pump of the device according to the invention can advantageously be regulated or controlled using one of the sensor signals, in particular a temperature signal, via the control unit. It is also advantageous that both the coolant pump and the corresponding control valves in the feed lines of the auxiliary units can be controlled directly on the basis of known or currently detected state variables of the units, such as the current power loss or a load profile.
- the cooling capacity of the main cooler segment and the existing secondary cooler segments can be increased by assigning one or more cooler fans to the main cooler segment and / or the existing secondary cooler segments.
- the system parameters detected by the control device can advantageously be taken into account when controlling or regulating this at least one cooler fan.
- the main cooler segment and the at least one secondary cooler segment are structurally integrated in a common cooling module.
- This integrated design enables space-saving, compact installation of the cooling module in the engine compartment of the motor vehicle.
- the common cooling module has a common inlet for the existing cooler segments.
- the cooling segments integrated in the common cooling module parallel to one another in the cooling and heating system.
- This parallel segmentation of the vehicle cooler enables the generation of various temperature subsystems in the heating and cooling system of the vehicle in a simple manner.
- the coolant pump can be advantageously used in this way integrate into the cooling and heating system of the vehicle so that the coolant is pressed through the cooling module.
- a device according to the invention is thus possible, in which only a single coolant pump supplies all subcooling circuits (temperature subsystems) at the same time, even when different temperature levels are present in these subcooling circuits.
- the common cooling module in each case has separate inlet channels and separate outlet channels for the individual, existing cooler segments. It is preferably provided that at least one secondary cooler segment has at least one secondary cooler inlet which is connected to the pressure side of the coolant pump. This measure can ensure that the coolant pump, which is present anyway, generates the required coolant volume flow. In this way, it is advantageously possible to implement an embodiment of the device according to the invention which can dispense with an additional coolant pump.
- the arrangement of the at least one secondary cooler inlet on the pressure side of the coolant pump ensures that the coolant flows through the additional cooler at a sufficient pressure. For the same reason, in embodiments in which at least one second unit is provided, this is to be connected advantageously on the pressure side of the coolant pump.
- a particularly advantageous embodiment of the device according to the invention for heating and cooling a motor vehicle results from the fact that the common cooling module and the bypass valves regulating the flow through the respective segments of this cooling module have a structural design are integrated in a common cooler module. This results in a compact, modular cooling module that can easily accommodate different requirements, such as a different number of thermal subsystems in the cooling circuit.
- the cooling system it is provided that at least two components or units are advantageously connected in series.
- the waste heat of one component can be used to heat another component.
- the waste heat from the cylinder head of the engine can be used to heat up the oil faster when the engine is warming up.
- a four-way mixing valve can advantageously be integrated in the cooling circuit, for example.
- the at least one coolant inlet of the engine can be shut off, for example by a valve, as claimed by the device according to the invention, there is the possibility of further reducing the required coolant flow when the internal combustion engine is switched off.
- waste heat from an aggregate integrated in the coolant circuit or another component can optionally be used to heat the internal combustion engine or to heat the interior.
- the implementation of a parking heater is possible.
- the first unit is an electrical circuit which it. requires that this circuit is operated in a significantly lower temperature range than the internal combustion engine.
- a particularly preferred embodiment of the cooling system according to the invention provides that the first unit is a power electronics circuit which is assigned, for example, to a generator, a starter, an (additional) electric drive motor or a starter generator, which in this case represents the second unit.
- Starter generators combine the function of conventional starters and conventional alternators or generators. Starter generators are strong sources of heat and therefore have to be cooled in many cases. Since they can be operated at temperatures which correspond to the temperatures of the coolant for cooling the internal combustion engine, their parallel connection to the internal combustion engine and / or to the main cooler is particularly advantageous.
- the coolant temperatures usually used for cooling internal combustion engines are generally too high for the associated power electronics. It is therefore particularly advantageous if the power electronics circuit assigned to the starter generator, for example, is connected to the cooling and heating system of the motor vehicle via a secondary cooler segment. In this way, the power electronics circuit can operate in a temperature range which is significantly below the temperature of the coolant used for cooling the internal combustion engine.
- the waste heat generated by the power electronics circuit or a starter or generator can advantageously be used for the rapid heating of further components present in the coolant circuit, such as the engine itself.
