Description

Technical Field

[0001] The present invention relates to a thermal management device and a method for operating a thermal management device. Background Art

[0002] In the sense of the present invention, a thermal management device is understood to be a device for achieving a supply of heat and / or cold to the vehicle. Optionally, waste heat is dissipated to the surrounding area or, in the case of a heat deficiency, heat is absorbed from the surrounding area by the thermal management device in order to make the heat available in the vehicle at a corresponding temperature level.

[0003] Fields of application of thermal management devices are in particular in vehicles with high-efficiency internal combustion engines and in hybrid and electric vehicles.

[0004] In the prior art, multiple coolant circuits or refrigerant circuits are sometimes installed in a vehicle, which dissipate waste heat to the surrounding area via multiple various heat exchangers in the front end of the vehicle. This results in a voluminous heat exchanger package, wherein difficulties are often encountered when finding a satisfactory fluid solution for the heat transfer task, because the heat exchangers have to share a limited fluid favorable space, or unfavorable conditions have to be deliberately accepted.

[0005] Furthermore, a problem with modern vehicles with efficient internal combustion engines or hybrid and electric vehicles is that insufficient heat is generated in the engine at the necessary temperature level so that any available waste heat is used with a heat pump, for example to provide adequate vehicle interior heating or heating of other components.

[0006] In vehicles according to the prior art, waste heat from the air conditioning system is still discharged to the surrounding area by means of a separate additional air-to-air heat exchanger or, in winter, heat is absorbed via the air-to-air heat exchanger as an evaporator.

[0007] An example of a heat management device according to the prior art is described in JP 19990286211 A2.

[0008] The disadvantage of the system according to the prior art is that the various technical solutions are implemented in parallel, resulting in a high installation space requirement for the entire system and negative interactions of the solutions which do not allow the desired high efficiency to be achieved.

[0009] Experts are also trying to reduce the refrigerant fill level in the refrigerant circuit, which is desirable for commercial, ecological and safety reasons, so that refrigerants with higher safety requirements can be used. Summary of the invention

[0010] Technical issues

[0011] The object of the present invention is to provide a thermal management device for a vehicle and a method for operating such a thermal management device, which takes up as little space as possible in the vehicle, has a simple structure, uses a simple refrigerant circuit with its main components, and is intended to operate with natural refrigerants such as carbon dioxide, propane, propylene, isobutane, ammonia as well as chemical refrigerants and chemical refrigerant mixtures.

[0012] Efficient thermal management concepts are also possible, so that sufficient heat is available to heat the vehicle.

[0013] Solution to the problem

[0014] This object is achieved by a heat management device and a method for operating such a heat management device according to the present disclosure. Improvements are also disclosed in the present disclosure.

[0015] The object of the invention is achieved in particular by a thermal management device for a vehicle, which comprises the basic components: a refrigerant circuit and a heat carrier network. The refrigerant circuit can be operated in a refrigerator function mode and a heat pump function mode. This means that, depending on the switching of the heat exchanger, the condenser and the condensation heat generated by it can be used for heating purposes, and on the other hand, the evaporator can be used for cooling and for absorbing heat in the refrigerant circuit when switching to the heat pump mode. The operation of the refrigerant circuit is always the same, that is, the evaporator or condenser is always functionally an evaporator or condenser. The water circuit is equipped with valves accordingly. The heat carrier network is a pipeline system for transporting a heat carrier fluid, in particular a water / glycol mixture, to cool and heat vehicle components. The heat carrier network comprises at least one heat carrier storage, also referred to and implemented as a central water / glycol tank, which serves as a reservoir, distributor and collector for a heat carrier mass flow. The reservoir can be operated with water or additionally with PCM (phase change material) or ice sludge to increase the heating or cooling capacity. Furthermore, additional reservoirs such as PCM or ice sludge reservoirs can be connected to the central water / glycol tank and used to cover performance peaks at maximum cooling / heating demands. The heat carrier network and thereby the multiple heat carrier supply sections are fed from the heat carrier reservoir, and the heat carrier network and thereby the multiple heat carrier supply sections can be switched modularly to various circuits. The formed circuits are used as various components using the reservoir according to the switching, and are used to receive heat or to dissipate heat via the heat carrier supply sections, which implement a circuit with a central low-temperature ambient heat exchanger.

[0016] Therefore, there are three types of heat carrier supply sections to be distinguished within the heat carrier network.

[0017] The first type involves an ambient heat carrier supply section that connects a heat carrier reservoir to a low temperature ambient heat exchanger by means of which waste heat is transferred from the thermal management device to the surrounding area, or ambient heat is transferred from the surrounding environment to the thermal management device by means of the low temperature ambient heat exchanger.

[0018] The second type of heat carrier supply section connects the various components into the circuit and is switched to connect to the heat carrier storage according to the heat transfer task.

[0019] Finally, a third type of heat carrier supply section is distinguished and formed in that the sub-circuit is switched to be connected within the heat carrier network and not connected to the heat carrier storage.

[0020] Preferably, a heat carrier pump and a heat carrier distributor unit are arranged at the heat carrier reservoir, so that the heat transfer fluid can flow by means of the pump through the heat carrier supply section connected in a circuit with the heat carrier reservoir.

[0021] The heat transfer fluid flow within the heat carrier network is switched by means of a heat carrier distributor unit to connect to the outlet of the heat carrier storage.

[0022] According to an advantageous embodiment of the invention, the individually controlled and regulated evaporator heat carrier supply section realizes the circuit of the evaporator with the heat carrier reservoir, the component heat exchanger and / or the battery heat exchanger and the refrigerant circuit.

[0023] Preferably, the heat carrier pump is arranged downstream of the evaporator along the flow direction in the heat carrier supply section of the evaporator.

[0024] According to another advantageous embodiment of the invention, the individually controlled and regulated condenser heater heat carrier supply section realizes a temporary closed circuit with the condenser and heater heat exchanger of the refrigerant circuit, wherein the heat carrier pump is arranged in the condenser heater heat carrier supply section.

[0025] Advantageously, a separately controlled and regulated heat transfer supply section of the component cooler is provided for realizing a circuit with a heat transfer storage and a component heat exchanger within the heat management device.

[0026] According to a further advantageous embodiment of the heat management device, the individually controlled and regulated condenser cooler heat transfer medium supply section implements a circuit with the heat transfer medium storage, the condenser of the refrigerant circuit and the heater heat exchanger.

[0027] The individually controlled and regulated cooler heat carrier supply section advantageously enables a circuit of the evaporator and / or the battery heat exchanger and / or the cooler with a refrigerant circuit.

[0028] According to a further preferred embodiment, the individually controlled and regulated component heater heat carrier supply section implements a circuit with a heat carrier reservoir, a component heat exchanger and / or a battery heat exchanger, and / or a cooler and an evaporator of a refrigerant circuit.

[0029] The electric auxiliary heater is advantageously arranged in the heat carrier network.

[0030] Additional energy storage can advantageously be arranged in the circuit. Said storage can be used to charge high load points, such as fast batteries, to a desired temperature level in advance.

[0031] The refrigerant used in the refrigerant circuit is preferably selected from the group consisting of 20 refrigerants R290 or R1270, R134a, R152a, R1234yf, R1234zf, R744 or R600a.

[0032] The object of the present invention is also achieved by a method for operating a thermal management device according to the aforementioned preferred embodiment, wherein in a combined cooling and heating mode, a condenser heater heat carrier supply section, an evaporator heat carrier supply section, and an ambient heat carrier supply section and a refrigerant circuit, the latter two being connected by switching according to the temperature level of the heat carrier in the heat carrier reservoir.

[0033] According to an alternative method for operating the thermal management device, in cooling mode, the cooling heat carrier supply section, the condenser cooler heat carrier supply section, and the component cooler heat carrier supply section, the ambient heat carrier supply section and the refrigerant circuit are connected by switching.

[0034] According to another alternative method for operating the thermal management device, in the heating mode, the component heater heat carrier supply section, the condenser heater heat carrier supply section, the ambient heat carrier supply section and the refrigerant circuit are connected by switching.

[0035] The idea of ​​the invention is that a plurality of air-to-air heat exchangers for coupling heat into or out of the surrounding area can be combined to form one low-ambient heat exchanger by combining the main components of the thermal management device with a refrigerant circuit and a heat carrier network. The resulting dimensions provide a low-ambient heat exchanger of sufficient size to quickly charge the battery when the vehicle is stationary in order to dissipate very high power levels (up to 30kW to 40kW) to the surrounding area. A water-fed refrigerant heat exchanger is actually easier to handle due to the good heat transfer characteristics of both fluids. A heat carrier reservoir integrated in the thermal management device allows heat to be stored and thereby buffered.

[0036] In the embodiment, the core points of the thermal management according to the present invention are explained with the schematic diagram of the principle shown.

[0037] The low-ambient heat exchanger is a heat exchanger provided in the front end of the vehicle, and may dissipate heat to the surrounding area, or may also absorb heat from the surrounding area.

[0038] In addition to heating in heat pump mode, a central water / glycol tank - also called heat carrier storage - serves as a distributor and collector for all heat carrier flows.

[0039] The heat carrier storage device may additionally comprise a pump and a distributor unit which accordingly conveys and distributes the water / glycol mixture.

[0040] Depending on the need for heating or cooling, the heat exchanger is supplied with a corresponding heat carrier or water mass flow at the front end in contact with the surrounding area. In heat pump mode, the device is particularly advantageous because a heat flow can be received from the surrounding air by means of a high water mass flow and a low temperature difference with the surrounding area, and the heat flow does not cause ice formation in the heat exchanger.

[0041] It is further advantageous that water as a heat carrier fluid does not change temperature due to pressure losses as is typically the case with refrigerants. It is further advantageous that the low ambient heat exchanger can be much larger than a single condenser of the refrigerant circuit acting as an evaporator. It is thus possible to receive sufficient heat from the surrounding area at low temperature differences.

[0042] The invention has the advantage that a simple system is available and that all available heat flows can be used.

[0043] The system advantageously comprises only one heat exchanger which is in contact with the surrounding area. This also allows for a better crash classification of the vehicle.

[0044] Particularly significant advantages are that the refrigerant circuit is managed with a lower liquid level and there is the possibility of using propane or other refrigerants with higher safety requirements but significantly better thermodynamic properties. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Further details, features and advantages of embodiments of the invention emerge from the following description of embodiments examples with reference to the associated drawings. The drawings show:

[0046] Figure 1 : Schematic diagram of the thermal management device in combined cooling and heating mode,

[0047] Figure 2 : Thermal management device in cooling mode, and

[0048] Figure 3 : Thermal management device in heating mode. DETAILED DESCRIPTION

[0049] Figure 1The schematic diagram of the heat management device 1 in the combined cooling and heating mode is shown. The active area of ​​the heat carrier network 3, also called the heat carrier supply section, is shown with the help of arrows indicating the flow direction of the heat carrier fluid. The combined cooling and heating mode shown is an application case, especially in the transition seasons of spring and autumn.

[0050] The thermal management device 1 comprises two main components, a refrigerant circuit 2 and a heat carrier network 3. The refrigerant circuit 2 is schematically shown in its basic form and comprises the components evaporator 4, condenser / gas cooler 5, internal heat exchanger 6, expansion mechanism 7 and evaporator 8 connected in a circuit. The internal heat exchanger 6 is also called subcooling countercurrent and is advantageously integrated in the refrigerant circuit 2 depending on the refrigerant used, but is not absolutely necessary. The refrigerant circuit can also be implemented for the production of work, with two-stage compression and corresponding cooling and two-stage expansion.

[0051] The thermal management device 1 also comprises a heat carrier network 3 for transporting a heat carrier fluid, both heat and cold, to the consumer. Typically, the heat carrier fluid is a mixture of water and glycol from the motor vehicle sector, but other heat carrier fluids for special cases are also conceivable. Depending on the application of the thermal management device 1, the heat carrier network 3 is connected by switching in various zones, also called heat carrier supply sections, in order to achieve specific heat transfer functions of the various components of the thermal management device 1.

[0052] The core element of the heat carrier network 3 is a heat carrier reservoir 11 for functionally storing a large amount of heat carrier fluid. From this central heat carrier reservoir 11 the heat carrier fluid is transported to specific areas of the heat carrier network 3. For even more complex heat carrier networks 3, the network can also be equipped with a plurality of heat carrier reservoirs connected to each other or working individually, depending on the application. Optionally, the reservoirs can also be insulated.

[0053] For this purpose, the heat carrier pump 13 is advantageously arranged directly on the heat carrier reservoir 11 and the heat carrier fluid is conveyed to the corresponding connection area of ​​the heat carrier network 3 via the heat carrier distributor unit 24. The ambient heat carrier supply section 25 has a particularly significant role in the heat carrier network 3. The low-temperature ambient heat exchanger 12 is connected in the ambient heat carrier supply section. The ambient heat carrier supply section 25 forms a circuit of the heat reservoir 11, the heat carrier pump 13, optionally the heat carrier distribution unit 24 and the low-temperature ambient heat exchanger 12. All heat exchanges, i.e. heat is absorbed from the surrounding area or heat is dissipated to the surrounding area, are carried out by means of the low-temperature ambient heat exchanger 12, which is usually arranged centrally at the front end of the motor vehicle. Heat from the surrounding area is correspondingly provided to the heat carrier fluid 11 by means of the ambient heat carrier supply section 25, or heat from the heat carrier fluid is dissipated from the heat carrier reservoir 11 to the surrounding area by means of the low-temperature ambient heat exchanger 12. In contrast to heat management devices according to the prior art, heat exchange from or to the surrounding area takes place only by means of a single central heat exchanger which is realized as and referred to as low-ambient heat exchanger 12 .

[0054] exist Figure 1 In the illustrated operating mode for combined cooling and heating, in addition to the above-mentioned ambient heat carrier supply section 25, a further heat carrier supply section is connected.

[0055] The condenser heater heat carrier supply section 27 forms a circuit of the condenser / gas cooler 5 of the refrigerant circuit by means of the heater heat exchanger 16 of the ventilation system 15, and in this case, the separate heat carrier supply section is driven by the heat carrier pump 19. In order to connect the various lines, in accordance with Figure 1 In the embodiment example of , two three-way valves 22 are provided, by means of which the circuit is connected within the heat carrier network 3 .

[0056] The evaporator heat carrier supply section 26 further functions in the circuit configuration of the described heat carrier network 3, forming a circuit starting from the heat carrier storage 11, through the heat carrier pump 13 and the heat carrier distributor unit 24. As shown in the principle schematic diagram, a plurality of component heat exchangers 18 are optionally connected to the evaporator 8 of the refrigerant circuit 2 via the four-way valve 14, and are incorporated into the circuit via the heat carrier pump 20 and the air cooler 17 of the vehicle's ventilation system 15. Finally, the circuit line is led back to the heat carrier storage 11.

[0057] Optionally, parallel branches are provided by means of a branch point 31, through which the heat carrier fluid is directed from the heat carrier reservoir 11 to the battery heat exchanger 9 and then to the heat carrier reservoir 11 via the multi-way valve 21. Figure 1In the description of FIG. 1 , a cooler 10 is additionally shown, but in the present control and circuit variation, the cooler 10 is not incorporated into the active heat carrier supply section.

[0058] Figure 2 The schematic diagram shows a thermal management device 1 in cooling mode, especially in the warm summer months, for cooling the vehicle. In addition to directly cooling the vehicle interior for the comfort of the vehicle occupants, for example, important components of the drive system as well as electronic components and batteries are also cooled.

[0059] In the present application mode for cooling, the ambient heat carrier supply section 25 with the low-temperature ambient heat exchanger 12 is optionally activated and again individually controlled and regulated. In addition, the functionally important cooling heat carrier supply section 29 is also connected and supplies the heat carrier fluid cooled in the evaporator 8 with the air cooler 17 and in parallel to the battery heat exchanger 9 and optionally additionally to the cooler 10 by means of the heat carrier pump 20. In the present circuit variant, the heat carrier supply section is not connected to the heat carrier fluid reservoir 11.

[0060] The heat carrier fluid from the heat carrier reservoir 11 is supplied to the component heat exchanger 18 in the component cooler heat carrier supply section 23 .

[0061] The heat carrier reservoir 11 is also connected to the condenser / gas cooler 5 via a condenser cooler heat carrier supply section 28 and also to the heater heat exchanger 16 of the vehicle's ventilation system 15 as a loop. The cooling of the components by means of the heat carrier reservoir 11 by means of the heat carrier fluid is carried out by cooling the heat carrier reservoir 11 to the ambient level by means of the low-temperature ambient heat exchanger 12, plus the temperature difference of the low-temperature ambient heat exchanger 12.

[0062] The cooling of the battery by means of the battery heat exchanger 9 and the cooling of the vehicle interior by means of the ventilation system 15 and the air cooler 17 are accomplished by means of the refrigerant circuit 2 acting as a refrigerator.

[0063] Figure 3The principle description of the thermal management device 1 in the heating mode is shown. For the heating principle, in particular for vehicles with efficient internal combustion engines, with an additional high-temperature ambient heat exchanger at the front end, and for hybrid and electric vehicles, it is particularly important to provide heat by means of the heat pump circuit and the function of the thermal management device 1. Thereby, the low-temperature ambient heat exchanger 12 in the ambient heat carrier supply section 25 serves as a coupling element of the thermal management device 1 with the surrounding area to absorb ambient heat with the purpose of subsequently converting the ambient heat and further utilizing the ambient heat to complete the heating task in the vehicle. The heat carrier reservoir 11 is connected to the evaporator 8 of the refrigerant circuit 2 in the component heater heat carrier supply section 30 by means of the component heat exchanger 18. In parallel, the battery heat exchanger 9 is also incorporated after the evaporator 8 in parallel with the component heater heat carrier supply section 30 by means of a branch point 31 used here as a collector point. In this circuit variant, the condenser heater heat carrier supply section 27 is again not connected to the heat carrier reservoir 11 and only forms a circuit via the condenser 5 of the refrigerant circuit 2 and the heater heat exchanger 16 of the ventilation system 15. To realize the circuit, a multi-way valve 21 and a three-way valve 22 are used in a typical manner.

[0064] Thus, by means of a single modularly constructed thermal management device 1 , the thermal management device 1 is provided with various functional types of combined cooling and heating operation, cooling operation as well as heating operation.

[0065] Particularly advantageous when implemented in a vehicle, only one low-ambient heat exchanger 12 needs to be individually controlled and regulated according to the required temperature level of the heat carrier fluid and connected to the heat carrier reservoir 11 , which brings advantages in terms of cost, weight and space.

[0066] Different volume flow rates can be advantageously achieved in the heat carrier network. In the current system, the condenser operates as an evaporator in heat pump mode. In order to prevent the condenser from freezing, the condenser operates at a low temperature difference between the refrigerant area and the surrounding area. However, this has a limiting effect on the superheating of the refrigerant, and also has a limiting effect on the heat source power to be absorbed from the surrounding area. In addition, the pressure loss of the condenser operating as an evaporator, wherein the required evaporator operation leads to an increase in installation space in many cases, such as a pressure drop requirement from 12mm to 16mm. In heat pump mode, for example, a volume flow rate of 202l / h to 300l / h is achieved in the evaporator heat carrier supply section 26, while the volume flow rate in the ambient heat carrier supply section 25 is between 1000l / h and 1500l / h. Thereby, high heat source power can be absorbed from the surrounding area at a very low temperature difference without freezing the low temperature ambient heat exchanger 12, and the refrigerant circuit can operate at a low but safe superheat. The additional necessary electric de-icing function or the enlargement of the wire diameter of the whole heat carrier network is eliminated. If de-icing is required, it is sufficient to open the three-way valve 22 or to increase the temperature in the heat carrier storage 11.

[0067] Cooling by means of an evaporator can also be carried out directly by means of the refrigerant or by a combination of direct and indirect.

[0068] The heat carrier storage 11 can also advantageously be realized in the form of at least two tanks which are selectively connected or disconnected from one another.
