Description

Technical Field

[0001] The present invention relates to an apparatus for handling fluids within a vehicle that is at least partially electrically powered. Background Technology

[0002] This device is also known in the prior art as an energy optimization module or thermal management unit. Thermal management units essentially perform the task of optimizing the thermal balance in a motor vehicle, aiming to reduce fuel consumption and emissions, ensure engine cooling at every operating point, and optimize interior comfort. Its purpose is to optimally conduct heat flow (e.g., heating and cooling) in the internal combustion engine, gearbox, or passenger compartment to reduce energy consumption and improve interior comfort. Heat is transferred from one object to another via a heat transfer medium (e.g., coolant or air), typically through forced convection. Heat is transferred from one fluid to another via heat exchangers (e.g., radiators, turbocharged air coolers, EGR coolers, or air conditioning condensers). The mass flow rate of the fluid is maintained, in particular, by a pump. Adequate cooling air mass flow is usually ensured by airflow, therefore many vehicles are equipped with electrically driven radiator fans (if airflow is insufficient).

[0003] Such thermal management modules are well known in the prior art. For example, integrated coolant bottle arrangements are known from WO 2017 / 223232 A2. Coolant bottle arrangements include containers configured for use in thermal systems. Examples of such thermal systems include cooling / heating systems for battery-powered electric vehicles, generators (e.g., engine-based systems), other physical infrastructure equipment, etc. Such a reservoir includes a first section and a second section. The second section connects to the first section at a storage interface to form a reservoir configured to store a fluid medium and / or allow the fluid medium to flow. The first section may include an integral channel providing a pathway for the flow of the fluid medium. The reservoir may also include component interfaces configured to facilitate the connection of components. Such components include, for example, pumps, battery pumps, transmission pumps, coolers, heaters, filters, aerators, valves, connectors, fans, or coolers.

[0004] Furthermore, a device for treating at least one fluid in a vehicle, particularly a vehicle at least partially electrically driven, is known from DE 10 2018 102 542 A1. This device includes at least one substantially plate-shaped first dispensing element and at least one second dispensing element arranged substantially parallel to the first dispensing element, wherein the first and / or second dispensing elements include at least one fluid handling element in at least some areas, and wherein the first and second dispensing elements include plastic in at least some areas, as well as a method for producing the device for treating at least one fluid (particularly at least one device according to the invention).

[0005] The known problem with thermal management modules is that several independent components are distributed throughout the vehicle and interconnected via hoses, cables, and control units. This results in hoses, cables, and control units sometimes being spread over long distances, and necessitates significant assembly work. There is also a high risk of leakage and short circuits, affecting the overall reliability and maintainability of the thermal management module. Furthermore, there are frequent problems due to leakage, such as pressure and voltage drops. Excessive cable length or corrosion can exacerbate this problem.

[0006] It is also particularly important to reduce flow losses at interfaces and fluid valves. This is based on the fact that flow losses at valves are especially caused by deviations from ideal geometry. These manifest as pressure differences upstream and downstream of the valve. Due to pressure losses, it may even be necessary to provide higher inlet pressures in the system to compensate for the pressure losses that occur. However, higher inlet pressures result in increased leakage.

[0007] Therefore, the present invention addresses the task of a thermal management module that overcomes problems arising from the prior art, based on a detailed description. Summary of the Invention

[0008] The solution according to the invention is to provide an apparatus for handling fluids within at least a partially electrically driven vehicle. The apparatus having a valve device includes a valve housing comprising at least two radially arranged port openings and at least one axially arranged port opening for fluid inflow and / or outflow. Furthermore, the valve device includes a valve body configured to be disposed within the valve housing and rotatable about an axial rotation axis R, wherein the valve body includes a first connecting channel and a second connecting channel, the first connecting channel being configured in an arcuate shape for connecting the two radially arranged port openings, and the second connecting channel being configured in an arcuate shape for connecting the radially arranged port opening to the axially arranged port opening. The at least two radially arranged port openings define a base plane B, the base plane B being configured orthogonal to the axial rotation axis R, and the first arcuate connecting channel defines a first connecting channel plane V, the first connecting channel plane V including a first tilt angle α greater than 0° relative to the base plane B.

[0009] This offers technical advantages, such as minimizing flow resistance through the arc-shaped connecting channels. Due to the initial inclination angle, the connecting channels do not directly confine each other. In other words, each connecting channel can be oriented without protrusions or edges that cause flow. This, in turn, significantly reduces the fluid pressure difference between the upstream and downstream of the connecting channels.

[0010] The fluid in this invention can be understood as any form of cooling water, coolant, or refrigerant. For example, ethylene glycol or a mixture of ethylene glycols is added to a water-based fluid to lower its freezing point. Alternatively, the fluid can be oil-based to eliminate its electrical conductivity. This provides the added advantage of being able to directly cool the battery.

[0011] The base plane B can alternatively be defined by the geometric center of the two port openings. Alternatively, it can be envisioned that the tilt angle α is defined as the deviation of the right angle between the first connecting channel plane V and the axis of rotation R. Thus, in a specific example, if the tilt angle α between the first connecting channel plane V and the base plane B is 5°, then the axis of rotation R intersects the first connecting channel plane V at a 95° angle.

[0012] According to a preferred embodiment, the first tilt angle α is less than 45°, particularly less than 30°, particularly less than 15°, and particularly less than 5°. This allows for full consideration of specific conditions. For example, the specific tilt angle α depends on the diameter of the valve body and the diameter of the connecting channel.

[0013] According to another embodiment, radially arranged port openings and axially arranged port openings define an axial plane A, and an arcuate second connecting channel defines a second connecting channel plane W, wherein the axial plane A includes a second inclination angle β greater than 0° relative to the second connecting channel plane W. This achieves the technical advantage of providing additional clearance, for example, to reduce resistance to flow through the arcuate connecting channel. The second inclination angle further reduces the mutual confinement of the connecting channels, and each connecting channel can be aligned as much as possible without protrusions and without edges that cause flow. This, in turn, reduces the fluid pressure difference upstream and downstream of the connecting channel.

[0014] According to another preferred embodiment, the second tilt angle β is less than 45°, particularly less than 30°, particularly less than 15°, and particularly less than 5°. This allows the device to be optimally adapted to specific conditions. For example, the specific tilt of the second tilt angle β depends on the diameter of the valve body and the diameter of the connecting channel.

[0015] According to an additional embodiment, the arcuate second connecting channel for connecting the radially arranged port opening to the axially arranged port opening includes an additional connecting channel for connecting the second radially arranged port opening to the axially arranged port opening. This provides the technical advantage of reducing the pressure difference, for example, by providing a first and / or second tilt angle in this embodiment. For example, the first tilt angle of the first connecting channel can be configured independently of the configuration of the second connecting channel. However, the second connecting channel can also be combined with the second radially arranged port opening.

[0016] To further reduce the pressure difference between the upstream and downstream of the valve, the valve body is configured as a ball and includes a bearing disposed outside the valve body. This has technical advantages, for example, the bearing cannot interact with the fluid flow inside the valve body. For example, the bearing is disposed above the valve body and simultaneously supports a drive shaft used to move the valve body from a first switching position to a second switching position. Alternatively, the valve body can be configured as a cylinder, in which case all other features associated with a cylindrical configuration can be combined.

[0017] According to a particularly advantageous embodiment, the valve body comprises at least two parts welded together. This has the technical advantage of making the valve body particularly easy to manufacture. For example, the individual parts can be manufactured by injection molding and then bonded or welded together. However, alternatively, the valve body can also be manufactured by additive manufacturing or by casting processes.

[0018] To further stabilize the bearing and prevent the valve body from tilting, the bearing includes a bearing ring allocated to the axial port opening.

[0019] To further reduce the pressure difference between the upstream and downstream of the valve, at least one port opening of the valve housing is equipped with a sealing element, wherein the inner diameter of the corresponding connecting channel is substantially the same as the inner diameter of the sealing element. Therefore, for example, a technical advantage is achieved by optimizing fluid flow not only within the connecting channel but also within the sealing element. In other words, the sealing element is designed such that its inner diameter continues or extends the connecting channel. Therefore, due to the protrusions in the sealing element, there is no fluid back pressure or other flow effects. This further reduces the pressure difference of the fluid. For example, this type of sealing element is assigned to each port opening.

[0020] According to another embodiment, a spring element is associated with a sealing element, wherein the spring element is arranged circumferentially and configured to apply an axial force to reduce leakage. The spring element can be configured, for example, as spring steel or an O-ring. The spring element allows the sealing element to abut the valve body without gaps, which further optimizes fluid flow and further reduces the pressure difference between the upstream and downstream of the valve body.

[0021] To further reduce leakage and improve the installability of sealing elements, the sealing elements include polytetrafluoroethylene (PTFE). This means it is made of or coated with PTFE. Furthermore, PTFE is particularly heat-resistant, which can also extend the service life of valve equipment.

[0022] According to another preferred embodiment, the valve body includes at least one profile assigned to the inlet and / or outlet of a first or second connecting channel. This achieves the technical advantage that the opening cross-section of the connecting channel can be continuous, for example, when transitioning from one switching position to another. For instance, this allows for better control of flow behavior.

[0023] Based on this, the profile is configured along the base plane of the valve housing. Therefore, the longitudinal extension of the profile is configured to be orthogonal to the axis of rotation R, which optimally ensures the controllability of the valve.

[0024] According to another embodiment, the device includes a device housing having a first housing section and a second housing section, wherein the first housing section and the second housing section are configured to be adjacent to each other by a fluid-impermeable profile wall. The profile wall includes a side oriented toward the first housing section and a side oriented toward the second housing section. Furthermore, the device includes at least one fluid handling element, wherein the fluid handling element includes a component for generating a controllable variable magnetic field disposed in the first housing section and a component in the form of a valve device movable through the generated magnetic field and disposed in the second housing section. This results in the technical advantage of, for example, that only magnetic coupling exists between the component for generating the controllable variable magnetic field and the component movable through the generated magnetic field. This magnetic coupling acts through the fluid-impermeable profile wall and allows the component movable through the generated magnetic field to be arranged for wet operation in the second housing section in the fluid. On the other hand, the component for generating the controllable variable magnetic field is disposed together with the control unit in a "hydraulically decoupled," dry first housing section. The separation between the electronic components in the water-bearing second housing section and the first housing section reduces the risk of leakage and short circuits. Furthermore, dynamic sealing is not required. This means there is no heat loss due to friction, and energy efficiency is improved. Overall, a higher level of efficiency can therefore be achieved. This means that the valve device can be fully housed within the second housing section.

[0025] According to another embodiment, the component for generating the controllable variable magnetic field includes a stator, and the component in the form of a valve device movable by the generated magnetic field includes a rotor. Due to the rotor-stator arrangement, torque can be generated via magnetic coupling through a fluid-impermeable contour wall, which can be used to transfer the valve body from a first switching position to a second switching position. Alternatively, the fluid handling element may include, for example, an electric motor, a coil device, or a switching magnet, as a component for generating the controllable variable magnetic field arranged in the first housing section.

[0026] Furthermore, torque can be transmitted to the valve body via a wet-running gearbox. This offers technical advantages, such as the torque generated at the rotor can be adapted to the desired function. For example, different stages can be used for transmission. The gearbox can be positioned directly in the fluid and thus within the second housing section. This eliminates the need for dynamic seals. Potentially necessary lubrication can be provided directly via cooling water, and any heat loss due to friction is directly dissipated into the cooling fluid.

[0027] According to another embodiment, the profile wall includes a cylindrical protrusion that at least substantially fills the interior of the stator disposed in the first housing section. This has technical advantages, for example, the protrusion of the profile wall determines the precise mounting position of the stator. The profile wall thus has a dual function: on the one hand, fluid impermeability essential to the present invention, and on the other hand, positioning of the stator in the first housing section.

[0028] Furthermore, the contour wall serves to center the rotor within the stator. According to yet another embodiment, a cylindrical protrusion is configured to receive the rotor arranged in the second housing section. This provides the additional advantage of, for example, optimal orientation of the rotor arranged in the second housing section relative to the stator. Furthermore, the cylindrical protrusion can serve as a rotor guide during operation, where fluid impermeability is not restricted while still ensuring separation between the water-bearing second housing section and the electronics in the first housing section.

[0029] According to another embodiment, the device includes a second fluid processing element, which includes a fluid pump. Therefore, for example, the technical advantage that the fluid circuit can be controlled by the fluid pump can be realized.

[0030] In a particular embodiment, the rotor axes of the fluid handling elements are arranged parallel to each other. This provides a particular advantage: manufacturing and assembly in this arrangement are exceptionally simple. Furthermore, individual components can be easily tested and replaced.

[0031] On the other hand, there is a device for handling fluids within at least a partially electrically driven vehicle, wherein the device includes a housing, a first housing section, and a second housing section, wherein the first housing section and the second housing section are configured to be adjacent to each other by a fluid-impermeable contour wall. Furthermore, the contour wall includes a side oriented toward the first housing section, a side oriented toward the second housing section, and at least one fluid handling element, wherein the fluid handling element includes a member arranged in the first housing section for generating a controllable variable magnetic field and a member arranged in the second housing section movable by the generated magnetic field.

[0032] This results in the technical advantage of having only magnetic coupling between, for example, the component used to generate the controllable variable magnetic field and the component that can move through the generated magnetic field. This magnetic coupling acts through a fluid-impermeable contour wall and allows the component that can move through the generated magnetic field to be arranged for wet operation in the fluid within the second housing section. On the other hand, the component used to generate the controllable variable magnetic field, together with the control unit, is arranged in a "hydraulically decoupled," dry first housing section. The separation between the electronic components in the water-bearing second housing section and the first housing section reduces the risk of leakage and short circuits. Furthermore, dynamic seals are not required. Therefore, there is no heat loss due to friction, and energy efficiency is improved. Overall, higher efficiency can thus be achieved.

[0033] In the context of this invention, a fluid-impermeable profiled wall is understood as a continuous separation layer configured to be uninterruptedly continuous, at least between the component for generating a controllable variable magnetic field and the component movable by the generated magnetic field. In this context, fluid impermeability means that fluid exchange cannot occur through the profiled wall. A fluid-impermeable profiled wall can, for example, be limited to a single fluid handling element. Alternatively, the profiled wall can also be understood as a continuous separation layer for accommodating several fluid handling elements. Unlike known elastically deformable seals based on elastomers, no leakage occurs due to flow around the profiled wall. An impermeable profiled wall is understood like a continuous shell surface. For example, a continuous interface can also be the surface of a plastic body that internally carries components movable by the generated magnetic field and can be controlled by components for generating a controllable variable magnetic field from the outer surface of the plastic body.

[0034] A component used to generate a controllable, variable magnetic field can be understood as any component applicable to generating a magnetic field with the assistance of an electric current. The magnetic field is configured to be controlled by a current supply, which in its simplest case means at least switching the magnetic field between on and off. However, the magnetic field strength can also be varied between switching on and off. For example, arrangements of electric coils, electromagnets, stepper motors, switched magnets, brushless motors, claw motors, or electric linear actuators can be conceived as such components.

[0035] On the other hand, permanent magnets, ferromagnets, or objects made of rare-earth-based materials can be conceived as components capable of moving through the generated magnetic field.

[0036] According to an advantageous further embodiment of the invention, the component for generating the controllable variable magnetic field includes a stator, and the component movable by the generated magnetic field includes a rotor. Due to the rotor-stator arrangement, torque can be generated through fluid-impermeable contour walls by means of magnetic coupling. Alternatively, the fluid handling element may include, for example, an electric motor, a coil arrangement, or a switching magnet, as a component arranged in the first housing section for generating the controllable variable magnetic field.

[0037] According to another embodiment, the profile wall includes a cylindrical protrusion that at least substantially fills the interior of the stator disposed in the first housing section. This has the technical advantage that, for example, the cylindrical protrusion of the profile wall determines the precise mounting position of the stator. The profile wall thus has a dual function: on the one hand, fluid impermeability essential to the present invention, and on the other hand, positioning of the stator in the first housing section.

[0038] According to yet another embodiment, the cylindrical protrusion is configured to receive a rotor arranged in the second housing section. This has additional advantages, such as optimal orientation of the rotor arranged in the second housing section relative to the stator. Furthermore, the cylindrical protrusion can serve as a rotor guide during operation, wherein fluid impermeability is not restricted while still ensuring separation between the water-bearing second housing section and the electronics in the first housing section.

[0039] According to another advantageous embodiment, the second housing section is configured to carry fluid and includes at least one connection for fluid inflow and / or outflow. This has technical advantages, for example, the second housing section can be designed without electrical interfaces. The focus is solely on fluid supply, diversion, and discharge, wherein the manufacture of the second housing section is characterized by the selection of inexpensive materials and suitable connection methods. For example, the second housing section can be manufactured using vibration welding or mirror welding, which is problematic due to thermal reasons when integrated with an electronic control unit and can therefore only be implemented separately. Several ports for fluid inflow and / or outflow can also be implemented. Ports represent customer interfaces. The hose diameter, number, and corresponding position of the ports can be varied. Depending on customer requirements, the orientation of the ports can also be adjusted, wherein variable adjustability of the ports is also conceivable.

[0040] To allow the entire device to be adapted as flexibly as possible to specific customer requirements, different functions can be assigned to each fluid handling element within the device. For this purpose, fluid handling elements include fluid pumps or fluid valves. Depending on the intended use, embodiments of the fluid handling elements are implemented in which, in each embodiment, the magnetic coupling remains connected to a fluid-impermeable contour wall, and components movable by the generated magnetic field are arranged for wet operation in the fluid within a second housing section.

[0041] According to a preferred embodiment, the rotor is associated with components for conveying and / or controlling fluid. Due to the magnetic coupling between the stator and rotor, magnets arranged on the rotor are set to rotate by the stator. Furthermore, different components can be arranged on the rotor itself, depending on the desired function of the corresponding fluid handling element. For example, a pump with an impeller or a rotating wheel can be used to pump fluid. To control or direct the fluid, for example, a rotary valve or a switching valve can be used.

[0042] According to an alternative embodiment, the component includes a switching element. This allows for the technical advantage of configuring, for example, the switching element as a rotary slide valve. This makes the device or fluid handling element suitable for different vehicles and different functions. Different installation spaces and different requirements of vehicle manufacturers necessitate different switching strategies. For example, fluid can be diverted by rotating a slide valve, and multiple ports and switching modes can be achieved.

[0043] According to an alternative embodiment, the component includes a rotating wheel. This has technical advantages, such as the ability to directly integrate the rotating wheel into the fluid circuit. The stator-rotor connection allows for pump functionality through rotation. For example, the rotating wheel is configured as an impeller.

[0044] According to an additional embodiment, a wet-running gearbox is associated with the rotor. This provides technical advantages, such as the torque generated at the rotor being adaptable to the required function. For example, different stages can be used for transmission. The gearbox can be arranged directly in the fluid and thus within the second housing section. This eliminates the need for dynamic seals. Potentially necessary lubrication can be provided directly by cooling water, and any heat loss due to friction is dissipated directly into the cooling fluid. As an alternative to this embodiment, the rotor can also be operated without a wet-running gearbox. For example, the rotor can be sealed to the fluid by means of seals. Therefore, the rotor can be dry-run.

[0045] In a particular embodiment, an electrical control unit is associated with the first housing section for controlling the device. The electrical control unit is necessary for the operation of the device and can be located either outside or inside the first housing section. It is also contemplated to operate the device with a customer-supplied external control unit, where an interface can be provided on the first housing section for this purpose. However, alternatively or additionally, the control unit may be located within the first housing section.

[0046] Based on this, the electrical control unit is arranged within the first housing section, adjacent to a fluid-impermeable contour wall. For example, by placing the electrical control unit against the fluid-impermeable contour wall within the first housing section, a technological advantage of effectively cooling the electrical control unit can be achieved. This cooling occurs without the risk of direct contact with the fluid, thus avoiding short circuits. Furthermore, the fluid can be heated using dissipated heat. Another advantage is the large temperature difference between the low coolant temperature and the chip temperature of the power electronic devices. For example, a temperature sensor can be arranged on one side of the electrical control unit (i.e., in the dry area) to measure the fluid temperature. The sensor will therefore measure through the fluid-impermeable contour wall, where the evaluation of the sensor signal can be performed directly in the dry area of ​​the first housing section.

[0047] According to another embodiment, the device includes a second fluid handling element, which includes a fluid pump. Therefore, for example, it can provide the technical advantage that an additional fluid circuit can be controlled by the second fluid pump.

[0048] In a particularly preferred embodiment, the device includes a third fluid handling element comprising a fluid valve. The fluid valve functions as a rotary spool valve. The rotary valve allows the device to be adapted to different vehicles, where varying installation spaces and requirements may necessitate, for example, the redirection of fluid flow. A switching interface allows switching from a parallel circuit to a series circuit.

[0049] According to a particular embodiment, the fluid valve includes a dual-rotary sliding arrangement with a first layer and a second layer. This results in the technical advantage of simultaneously arranging and operating two switching positions in a single rotary valve having only one fluid handling element. For example, no additional fluid handling element is required because both switching positions can be controlled using only a single rotor-stator arrangement. For example, it may be necessary to supply fluid to different mounting spaces on different vehicles. To avoid having to replace the entire fluid handling element, rotary valve assemblies with different layers can be used. Thus, depending on the desired purpose, different fluid passages are interconnected without changing the entire fluid handling element. For example, the first layer may include a valve position allowing 90° rotation, while the second layer may include a valve position allowing 180° rotation, i.e., straight-line forward movement. The desired functionality is achieved by appropriately utilizing the associated ports of the rotary valve assembly in the first or second plane.

[0050] According to another embodiment, the device includes an expansion valve for an associated heat exchanger. This provides the technical advantage that, for example, the heat exchanger can also be integrated into the device, and the control of the expansion valve can be performed in a manner similar to other fluid handling elements of the device. The manufacture and assembly of the device are further simplified.

[0051] Based on this, the heat exchanger includes an associated heating device. Preferably, the heating device can be integrated into the heat exchanger, allowing direct heating of the fluid, which can then be used to heat a battery, engine, or vehicle interior. The heat exchanger (also known as a cooler) will thus have the capability of active heating or cooling.

[0052] Such heat exchangers are typically made of brazed stacked sheets. The plates are brazed in such a way that a channel for the first fluid is always in alternating thermal contact with a channel for the second fluid. This large contact area allows for optimal heat transfer. For example, thermoformed sleeves can be brazed into a package of stacked metal sheets, which can then be filled with heating wires and insulating ceramic, similar to a conventional heating cylinder. The heating device can also operate inductively, for example, where an inductively heatable object is inserted and heated via a circulating induction coil. The use of a combined control unit is also envisioned, which would save on additional cabling and simplify module integration. Overall, this heat exchanger eliminates the need for additional hose connections and makes the device more compact.

[0053] According to another embodiment, the first housing section includes a removable first cover element. This provides the technical advantage that components of electronic devices, such as those in dry areas, can be directly accessed for maintenance purposes. Therefore, inspection or maintenance is greatly simplified.

[0054] According to an additional embodiment, the second housing section includes a removable second cover element. This also provides the technical advantage of allowing direct access to all wet-operating parts of the equipment for maintenance purposes. Inspection or maintenance is also greatly simplified.

[0055] According to a particularly preferred embodiment, the device includes a first fluid circuit associated with a first fluid handling element and a second fluid circuit associated with a second fluid handling element. This makes the device particularly easy to operate. In combination with a dual rotary spool valve arrangement, for example, a total of four fluid circuits can be operated with two fluid handling elements, each having two switching positions in the rotary spool valve. Additional functionality can be provided by combining serial or parallel arrangements.

[0056] In a particular embodiment, the rotor axes of the fluid handling elements are arranged parallel to each other. This provides a particular advantage: production and assembly in this arrangement are exceptionally simple. Furthermore, individual components can be easily tested and replaced.

[0057] To improve the flexibility of the device and its integration into vehicles, the ports for fluid inflow and / or outflow are arranged in a plane that is substantially orthogonal to the orientation of the rotor axis of the fluid handling element. Attached Figure Description

[0073] Figure 1 An exploded view of an apparatus 100 according to the invention for processing fluids according to a first embodiment is shown. The apparatus 100 is intended for use in vehicles that operate at least partially on electricity. Therefore, it can be used in both purely electric vehicles and hybrid vehicles.

[0074] The device 100 includes a first housing section 200 and a second housing section 300, wherein the first housing section 200 and the second housing section 300 are configured to be adjacent to each other by a fluid-impermeable profile wall 150. The profile wall 150 is configured as a single piece. In this embodiment, the profile wall 150 is also the outer wall of the second housing section 300, thereby sharing the same side of the second housing section 300 oriented toward the first housing section 200.

[0075] On the side facing the first housing section 200, the profile wall 150 includes a plurality of cylindrical protrusions 152. Applied to these cylindrical protrusions 152 are stator-shaped components (210A, 210B, 210C) for generating a controllable variable magnetic field. The cylindrical protrusions 152 protrude into the interior of each arranged stator and fill the interior in such a way that hollow cylinders are disposed on the side of the second housing section 300, and components 310A, 310B, 310C, designed to be movable by the generated magnetic field, can be inserted into the second housing section 300. The components 210A, 210B, 210C, 210D for generating the controllable variable magnetic field are configured as stators of stepper motors in this embodiment, but they could also be configured as conventional motors, brushless DC motors (e.g., claw motors), or solenoid valves.

[0076] On the side of the profile wall 150 oriented toward the second housing section 300 (not shown), there are components 310A, 310B, and 310C, which are configured to be movable by a magnetic field generated by corresponding associated components 210A, 210B, and 210C for generating a controllable variable magnetic field. Components 310A, 310B, and 310C, configured to be movable by the generated magnetic field, each includes a rotor with an associated magnet. The rotor is rotated by a stator, thereby allowing the components 310A, 310B, and 310C configured to be movable by the magnetic field to be controlled by the stator. Components 310A, 310B, and 310C movable by the generated magnetic field are associated with components for conveying and / or controlling fluid. For example, the stator of component 210B for generating the controllable variable magnetic field is associated with a switching element 330 configured as a rotary slide valve. Due to the rotary slide valve, different installation spaces and different requirements can be achieved through different loop strategies. The fluid can be diverted, and different port and switching modes can be combined.

[0077] The stators of components 210A and 210C, used to generate the controllable variable magnetic field, are each associated with an impeller 340. The impeller is configured, for example, as an impeller and is directly integrated into the fluid circuit within the second housing section 300. Torque is generated from the stator via magnetic coupling to the rotor, which causes the impeller to rotate. Therefore, the impeller can be used as a pump for the corresponding associated fluid circuit.

[0078] Rotors associated with components 310A, 310B, and 310C, configured to move via a magnetic field, are respectively placed in cylindrical protrusions 152 of the contour wall 150 in the second housing section 300. In other words, the cylindrical protrusions 152 enable both precise arrangement of the stator in the first housing section 200 and precise arrangement of the rotor in the second housing section 300, thereby achieving a precise association between the rotor and stator. Therefore, the cylindrical protrusions perform a dual function: on the one hand, the allocation of the rotor and stator, and on the other hand, the fluid seal separation between the first housing section 200 and the second housing section 300, which can be termed hydraulic decoupling.

[0079] The combination of stator-shaped components 210A, 210B, and 210C arranged in the dry first housing section 200 for generating a controllable variable magnetic field, and corresponding associated components 310A, 310B, and 310C arranged in the wet second housing section 300 and operated across the contour wall 152 by magnetic coupling, each describe fluid handling elements 110A, 110B, and 110C.

[0080] An exception is component 210D in the form of a stepper motor for generating a controllable variable magnetic field. This is arranged in the dry first housing section 200. However, the expansion valve 370 is associated with the stepper motor. Compared to the fluid handling elements 110A, 110B, 110C already described, there is no continuous fluid-impermeable profile wall 150 between component 210D for generating the controllable variable magnetic field and the component movable through the generated magnetic field. The latter is integrated into the housing of the expansion valve 370, and the expansion valve 370 is arranged only parallel to the other fluid handling elements 110A, 110B, 110C on the housing section of device 100, where the stepper motor is integrated into the dry area of ​​the first housing section 200. To seal the necessary openings in the fluid-impermeable profile wall 150 for the expansion valve 370 to pass through, it is recommended to arrange O-rings.

[0081] In general, in this embodiment, device 100 includes a first fluid handling element 110A configured as a fluid pump. Furthermore, device 100 includes a second fluid handling element 110C, which also includes a fluid pump. This allows for the operation of two separate fluid loops or allows fluid to be delivered from two separate fluid loops. Additionally, device 100 includes a third fluid handling element 110B, which includes a switching element 330 or a fluid valve. The fluid valve is configured with a rotary slide valve, and the rotary slide valve allows device 100 to adapt to different vehicles. Different installation spaces and different requirements of the vehicle can be accommodated, for example, by redirecting the fluid. By switching the rotary slide valve, a switch can be made from a parallel fluid loop to a series fluid loop. Furthermore, a proportional mixing ratio can be provided. Additionally, device 100 includes a component 210D in the form of a stepper motor for generating a controllable variable magnetic field, wherein an expansion valve 370 is associated with component 210D for operating a heat exchanger 380.

[0082] All fluid handling elements (110A, 110B, 110C) are arranged on the device 100 such that the rotor shafts (not shown) of the fluid handling elements 110A, 110B, 110C are arranged parallel to each other. This significantly simplifies the fabrication and assembly of the entire device 100, allowing for easy testing and replacement of additional individual components.

[0083] Multiple ports 320A, 320B, 320C, and 320D are arranged on the second housing section 300 for fluid inflow and / or outflow. These ports serve as customer interfaces and can be modified as needed in terms of pipe diameter and corresponding location. This embodiment includes a total of four ports 320A, 320B, 320C, and 320D, which respectively discharge fluid laterally from and introduce fluid laterally into the second housing section 300. One port 320D serves as a connection to a heat exchanger 380. The heat exchanger 380 is associated with a stepper motor-type component 210D in the dried first housing section 200 for generating a controllable variable magnetic field. The heat exchanger 380 is also associated with an expansion valve 370.

[0084] The device 100 also includes an electrical control unit 220, which is also arranged in the dry first housing section 200. The electrical control unit 220 is configured as a flat object, as is typically used for, for example, a control panel. The control unit 220 is arranged above stator-shaped components 210A, 210B, 210C, 210D for generating a controllable variable magnetic field. The electrical control unit 220 is essential for controlling the device 100. For example, the control unit 220 could also be arranged between the various stators within the first housing section 200, but adjacent to a fluid-impermeable profile wall 150. This would be advantageous because the electrical control unit 220 can be additionally cooled without the risk of direct contact with the fluid. Furthermore, heating can be provided through heat losses that occur during the operation of the electrical control unit 220.

[0085] The first housing section 200 includes a removable first cover element 202. This first cover element 202 facilitates access to all electronic components—such as the electrical control unit 220 or components 210A, 210B, 210C, 210D for generating a controllable variable magnetic field (which are mounted within the first housing section 200). Therefore, components of the electronic devices in the drying area and device 100 can be directly accessed for maintenance, inspection, or even testing purposes. Furthermore, the first cover element 202 includes a connector port 204 that can be used as an additional interface for customers. For example, device 100 can be connected and operated using a customer's own control unit.

[0086] Therefore, the second housing section 300 also has a removable second cover element 302. This second cover element 302 can also be removed for maintenance purposes, thereby allowing direct access to all wet-operating components of the device 100. For example, defective components can also be replaced without removing the entire device 100 directly from the relevant vehicle.

[0087] As already explained, the first housing section 200 and the second housing section 300 are configured to be adjacent to each other via a fluid-impermeable profile wall 150. The profile wall 150 is configured as a single piece. In this embodiment, almost all of the fluid handling elements 110A, 110B, and 110C are arranged on a continuous fluid-impermeable profile wall 150. The continuous fluid-impermeable profile wall 150 is also the outer wall of the second housing section 300.

[0088] Figure 2AA detailed longitudinal section of the fluid handling element 110A of the device 100 according to the invention is shown. The device 100 includes a first housing section 200 and a second housing section 300, wherein the first housing section 200 and the second housing section 300 are configured to be adjacent to each other by a fluid-impermeable profile wall 150. The profile wall 150 is also the outer wall of the second housing section 300, and thus its outer wall is identical to the side of the second housing section 300 oriented toward the first housing section 200.

[0089] The profile wall 150 includes a protrusion 152 on the side facing the first housing section 200. The protrusion 152 is used to surround the stator-shaped component 210A that generates a controllable variable magnetic field, and the protrusion 152 protrudes completely through the interior of the stator, almost completely filling it.

[0090] Furthermore, the electrical control unit 220 for the control device 100 is located within the first housing section 200. It is arranged above the stator-shaped component 210A for generating a controllable variable magnetic field. The stator-shaped component 210A for generating the controllable variable magnetic field and the electrical control unit 220 for the control device 100 are enclosed by the first cover element 202 and protected from external influences such as dust, moisture, or mechanical effects.

[0091] Within the second housing section 300, configured to carry fluid, a movable component 310A movable by a generated magnetic field is arranged. The movable component 310A includes a rotor 314 with an associated magnet. The rotor 314 is precisely inserted into a protrusion 152 of the profile wall 150, ensuring precise alignment between the rotor 314 and the stator. The rotor 314 is configured to rotate by the stator, thereby configuring the movable component 310A to rotate and thus controllable by the stator. To enhance the functionality of the rotor-stator arrangement, an insulator (not shown) is arranged radially between the rotor 314 and the protrusion 152. Ferritic filler, for example, is suitable for this purpose. A rotating wheel 340 is arranged below the rotor 314, which functions as a pump for conveying fluid by rotation. The rotating wheel 340 is located inside a rotating wheel housing 342, with a fluid inflow opening 344 located at the lower end of the rotating wheel housing 342. Due to the radial rotation of the impeller 340, fluid flows into the impeller housing 342 through the fluid inlet opening 344 and out through the fluid outlet opening (not shown). Therefore, the impeller housing 342 can be incorporated into the second housing section 300 as a separate component that varies depending on the impeller size and / or desired pump performance. The rotor 314 includes a rotor axis 312A, and a magnetically movable component 310A, including the rotor 314 and the impeller 340, is arranged rotationally symmetrically with respect to this rotor axis 312A.

[0092] Figure 2B A longitudinal cross-sectional view of an alternative embodiment of the fluid handling element 110 of the device 100 according to the invention is shown. This embodiment also includes a first housing section (not shown) and a second housing section (not shown), wherein the first housing section 200 and the second housing section 300 are configured to be adjacent to each other by a fluid-impermeable profile wall 150. The profile wall 150 includes a protrusion 152 on its side oriented toward the first housing section 200. The protrusion 152 is used to surround a stator-shaped member 210 for generating a controllable variable magnetic field. The stator includes a first stator 210-1 and a second stator 210-2. The first stator 210-1 and the second stator 210-2 are arranged adjacent to each other in the direction of the rotor axis 312.

[0093] A component movable by the generated magnetic field is arranged within a second housing section 300 configured to carry fluid. The component movable by the generated magnetic field includes a first component 310-1 movable by the generated magnetic field and a second component 310-2 movable by the generated magnetic field.

[0094] The first component 310-1, which can move through the generated magnetic field, is associated with the magnetic field of the first stator 210-1, and the second component 310-2, which can move through the generated magnetic field, is associated with the magnetic field of the second stator 210-2.

[0095] Furthermore, the first component 310-1, which can be moved by the magnetic field generated by the first stator 210-1, includes a first rotor 314A with associated magnets.

[0096] Therefore, the second component 310-2, which can be moved by the magnetic field generated by the second stator 210-2, includes a second rotor 314B with associated magnets.

[0097] Two rotors 314A and 314B are precisely inserted into the protrusion 152 of the contour wall 150 in the second housing section 300. The first rotor 314A is associated with the first stator 210-1. The first rotor 314A is set to rotate by the first stator 210-1, thereby the first member 310-1, which can be moved by the magnetic field of the first stator 210-1, can be set to rotate and thus can be controlled by the first stator 210-1.

[0098] The second rotor 314B is associated with the second stator 210-2. The second rotor 314B is set to rotate by the second stator 210-2, so that the second member 310-2, which can be moved by the magnetic field of the second stator 210-2, can be set to rotate and thus can be controlled by the second stator 210-2.

[0099] Rotor shaft 316 connects the first rotor 314A to the first rotating wheel 340A, which can rotate to function as a pump to transport fluid. The first rotating wheel 340A is located within a rotating wheel housing 342A, with a fluid inlet opening 344A located at the lower end of the rotating wheel housing 342A. Due to the radial rotation of the rotating wheel 340A, fluid flows into the rotating wheel housing 342A through the fluid inlet opening 344A and out through the fluid outlet opening 346A.

[0100] The second rotor 314B is connected to the second rotating wheel 340B via a hollow rotor shaft 317. The second rotating wheel 340B can be used as a pump to transport fluid by rotation. The second rotating wheel 340B is located inside the rotating wheel housing 342B, through which fluid flows into the rotating wheel housing 342B via a laterally arranged fluid inlet port 344B. Rotation of the rotating wheel 340B causes the fluid to flow out radially through the fluid outlet opening 346B.

[0101] The first rotating wheel housing 342A and the second rotating wheel housing 342B are separated from each other by a separator 348. The rotor shaft 316 associated with the first rotor 314A and the first stator 210-1 extends through the hollow rotor shaft 317 and through the second rotating wheel housing 342B. For example, the hollow rotor shaft 317 can be directly fixed to the separator element 348.

[0102] The first rotating wheel 340A can be operated by selectively controlling the first stator 210-1 via an electrical control unit 220 (not shown). The second rotating wheel 340B can operate independently of the first rotating wheel 340A by selectively controlling the second stator 210-2. Here, rotors 314A and 314B include a common rotor axis 312, and both the first member 310-1, movable by the magnetic field generated by the first stator 210-1, and the second member 310-2, movable by the magnetic field generated by the second stator 210-2, are arranged rotationally symmetrically with respect to this common rotor axis 312.

[0103] This means that two different fluid pumps can be arranged and operated within a compact housing. This results in the added advantage that two different fluid circuits can deliver fluids separately from each other within device 100. By separating stators 210 into a first stator 210-1 and a second stator 210-2, the two pumps can be controlled at different and diverging speeds. This leads to a high degree of flexibility, and different operating modes can be followed in separate fluid circuits without considering any dependencies or influences between the fluid circuits.

[0104] To improve the functionality of the device 100, an insulator (not shown) may be arranged in the radial direction between the first rotor 314A and the fluid-impermeable profile wall 150. Similarly, an insulator (not shown) may be arranged in the radial direction between the second rotor 314B and the fluid-impermeable profile wall 150. For example, a ferrite filler may be used here.

[0105] Figure 2C A detailed longitudinal section of a fluid handling element 110 of a device 100 according to another embodiment of the invention is shown. This embodiment also includes a first housing section (not shown) and a second housing section (not shown), wherein the first housing section 200 and the second housing section 300 are configured to be adjacent to each other by a fluid-impermeable profile wall 150. The profile wall 150 includes a protrusion 152 on its side oriented toward the second housing section 300. A stator-shaped member 210 for generating a controllable variable magnetic field is inserted into the protrusion 152. The stator includes a first stator 210-1 and a second stator 210-2. The first stator 210-1 and the second stator 210-2 are arranged adjacent to each other in the direction of the rotor axis 312.

[0106] A component movable by the generated magnetic field is arranged in a second housing section 300, which is configured to carry fluid. The component movable by the generated magnetic field includes a first rotor 314A and a second rotor 314B.

[0107] The first rotor 314A is associated with the magnetic field of the first stator 210-1, and the second rotor 314B is associated with the magnetic field of the second stator 210-2.

[0108] Two rotors 314A and 314B are arranged in the second housing section 300 around the protrusion 152 of the profile wall 150. The first rotor 314A is associated with and rotated by the first stator 210-1 and is therefore controllable by the first stator 210-1.

[0109] The first rotor 314A is connected to the first rotating wheel 340A, which can be used as a pump to transport fluid by rotation. The first rotating wheel 340A is arranged radially outside the first rotor 314A and is located inside the rotating wheel housing 342A.

[0110] Due to the radial rotation of the rotating wheel 340A, fluid enters the rotating wheel housing 342A through the fluid inlet port 344A arranged on the side and flows out through the fluid outlet port 346A.

[0111] The second rotor 314B is associated with the second stator 210-2. The second rotor 314B is rotated by the second stator 210-2 and can therefore be controlled by the second stator 210-2.

[0112] The second rotor 314B is connected to the second rotating wheel 340B, which functions as a pump for pumping fluid by rotation. The second rotating wheel 340B is located radially outside the second rotor 314B and is arranged within the rotating wheel housing 342B. Fluid flows into the rotating wheel housing 342B from below via the fluid inlet port 344B. Due to the rotation of the rotating wheel 340B, the fluid is discharged radially through the fluid outlet opening 346B.

[0113] The first rotating wheel housing 342A and the second rotating wheel housing 342B are configured to be separated from each other by means of a separating element 348. For example, the separating element 348 is arranged radially outward on a protrusion 152 of the profile wall 150, and the protrusion 152 includes a retainer formed for this purpose.

[0114] The first rotating wheel 340A can be operated by selectively controlling the first stator 210-1 via an electrical control unit 220 (not shown). The second rotating wheel 340B can operate independently of the first rotating wheel 340A by selectively controlling the second stator 210-2. Here, rotors 314A and 314B include a common rotor axis 312, and both the first stator 210-1 and the second stator 210-2, as well as the first rotating wheel 340A and the second rotating wheel 340B, are arranged rotationally symmetrically relative to this common rotor axis 312.

[0115] This means that two different fluid pumps can be arranged and operated within a compact housing. This results in the added advantage that two different fluid circuits can deliver fluids separately from each other within device 100. By separating stators 210 into a first stator 210-1 and a second stator 210-2, the two pumps can be controlled at different and divergent rotational speeds. This leads to a high degree of flexibility, allowing different operating modes to be followed in separate fluid circuits without considering any dependencies or influences between the fluid circuits. Figure 2B Compared to the previous embodiment, the fluid handling element 110 in this embodiment requires significantly less axial mounting space. This is due to the shape of the outer rotor. The stator is arranged inside the rotor, and the associated rotating wheel is also located radially outside the rotor. This significantly increases the outer diameter of this embodiment of the fluid handling element, thereby providing higher overall operational smoothness and greater resistance to pressure waves. On the other hand, the inner stator can be configured to be smaller, thereby reducing manufacturing costs. In another embodiment, an outer rotor arrangement with only one stator and only one associated rotor is also conceivable.

[0116] To improve the functionality of the device 100, an insulator (not shown) may be arranged between the first rotor 314A and the fluid-impermeable profile wall 150. Similarly, an insulator (not shown) may be arranged between the second rotor 314B and the fluid-impermeable profile wall 150. For example, a ferrite filler may be suitable for this purpose.

[0117] Figure 3 A longitudinal cross-sectional view of the fluid handling element 110A of the device 100 according to the invention is shown. A stator-shaped component 210A for generating a controllable variable magnetic field is arranged in a first housing section (not shown). Separated from the profile wall (not shown) and thus in an adjacent second housing section 300 (not shown), a component 310A in the form of a rotor 314 configured to be movable by the magnetic field is arranged. The rotor 314 is surrounded in the radial direction by an insulator (not shown). The rotor 314 also includes two bearings 313 configured to receive the rotor shaft. An actuating wheel 340 for radial fluid outflow is located in the lower section of the rotor 314.

[0118] In the perspective view, below the rotating wheel 340 is the rotating wheel housing 342. The rotating wheel housing 342 shows a fluid inlet port 344, centrally located in the base of the rotating wheel housing 342. Additionally, the rotating wheel housing 342 includes a fluid outlet opening 346 disposed in its sidewall. Due to the radial rotation of the rotating wheel 340, fluid flows into the rotating wheel housing 342 through the fluid inlet port 344 and flows out through the fluid outlet port 346. This produces the pumping action of the fluid handling element 110A.

[0119] Figure 4 A detailed longitudinal section of another fluid handling element 110B of the device 100 according to the invention is shown. The device 100 includes a first housing section 200 and a second housing section 300, wherein the first housing section 200 and the second housing section 300 are configured to be adjacent to each other by a fluid-impermeable profile wall 150. The profile wall 150 is also the outer wall of the second housing section 300, and thus its outer wall is identical to the side of the second housing section 300 oriented toward the first housing section 200.

[0120] The profile wall 150 includes a protrusion 152 on the side facing the first housing section 200. The protrusion 152 is used to surround the stator-shaped component 210B that generates a controllable variable magnetic field, and the protrusion 152 protrudes completely through the interior of the stator, almost completely filling it.

[0121] Furthermore, the electrical control unit 220 for the control device 100 is located within the first housing section 200 and is arranged above the stator-shaped component 210B for generating a controllable variable magnetic field. The stator-shaped component 210B for generating the controllable variable magnetic field and the electrical control unit 220 for the control device 100 are enclosed by the first cover element 202 and protected from external influences such as dust, moisture, or mechanical effects.

[0122] Within the second housing section 300, configured to carry fluid, a movable component 310B, movable by a generated magnetic field, is arranged. The movable component 310B includes a rotor 314 with associated magnets. The rotor 314 is precisely inserted into a protrusion 152 of the profile wall 150, ensuring precise alignment between the rotor 314 and the stator. The rotor 314 is rotated by the stator, thereby causing the movable component 310B to be rotated and thus controlled by the stator. To improve the functionality of the rotor-stator arrangement, an insulator (not shown) is arranged radially between the rotor 314 and the protrusion 152. Ferritic filler, for example, is suitable for this. A switching element 330 is arranged below the rotor 314. The switching element can be configured as a rotary slide valve, thereby allowing the fluid to be diverted depending on the specific position of the rotary slide valve. Fluid diversion allows for multiple ports and switching modes within the device 100. This makes the device 100 or fluid handling element 110B suitable for different vehicles and corresponding desired functions. Port 320B is arranged laterally on the switching element 330, and the port is configured for fluid inflow and / or outflow. The fluid handling element 110B includes a rotor axis 312B, and the movable component 310B, rotor 314, and switching element 330 are arranged rotationally symmetrically with respect to the rotor axis 312B.

[0123] Figure 5A schematic diagram of a wet-running gearbox 350 according to the device 100 of the present invention is shown. The wet-running gearbox 350 includes a drive element 352 that receives the torque of the rotor. The torque causes a drive worm 354 to rotate via the drive element 352. A transversely arranged gear 356 is coupled to an associated gear stage 358. A rotary sliding opening 359 is located directly at the gear stage 358. In the assembled state, the output element of a rotary slider (not shown) protrudes through the rotary sliding opening 359 and directly engages with the gear stage 358 in the wet-running gearbox 350. This allows for precise control of the position of a switching element 330 configured as a rotary slider. Due to the general self-locking of the wet-running gearbox 350, no force (magnetic or electrical) is required to hold the rotary slider in place. This provides a considerable advantage, for example, for proportional operation. With this wet-running gearbox 350, any number of gear stages 358 can be coupled to determine the position of the coupled switching element 330 based on the stator ultimately controlled by the electrical control unit 220. The wet gearbox 350 is disposed directly in the fluid and therefore in the second housing section 300. This means that no dynamic seal is required. The necessary lubrication of the wet-running gearbox 350 is performed directly via the cooling fluid, and heat loss due to friction is dissipated directly into the cooling fluid.

[0124] Figures 6A to 6G Several schematic diagrams of a dual rotary valve arrangement 360 according to the device 100 of the present invention are shown. A simple rotary valve arrangement includes a so-called 2x90° deflection. These 2x90° deflections include the disadvantage that the channels cannot cross two different planes to connect with each other. The dual rotary valve arrangement 360 according to the present invention includes a first layer 360A and a second layer 360B. The advantage of this dual rotary valve arrangement 360 is that both rotary valves can operate simultaneously using only one rotary valve arrangement. This saves the need for an additional fluid handling element 110B or additional rotary valves that must operate with an additional stator-rotor arrangement.

[0125] Figure 6A A schematic diagram of the rotary valve wall 363 of the dual rotary valve arrangement 360 is shown. The rotary valve wall 363 is part of the housing that houses the rotary valve—in this embodiment, it has upper channel connecting elements and lower channel connecting elements 364, 365. The rotary valve wall 363 includes a plurality of inlet openings and outlet openings 362A, 362B arranged in a first plane 360A or a second plane 360B. Here, only one upper inlet and outlet opening 362A is located on the upper first plane 360A, while three lower inlet and outlet openings 362B are located on the lower second plane 360B. The inlet openings 362A and outlet openings 362B are arranged 90° apart from each other around the entire circumference of the rotary valve wall 363.

[0126] Figure 6BThis is a schematic diagram of a double rotary valve arrangement 360. The rotary valve wall 363 includes an upper first layer 360A with upper inlet and outlet openings 362A and a lower second layer 360B with a total of three lower inlet and outlet openings 362B. An upper channel connecting element 364 and a lower channel connecting element 365 are located within the rotary valve wall 363. The two channel connecting elements 364 and 365 are arranged to be rotatable relative to the rotary valve wall 363. However, the upper channel connecting element 364 and the lower channel connecting element 365 cannot rotate relative to each other. Therefore, they are configured with a common channel connecting element.

[0127] The upper channel connecting element 364 is configured in a T-shape with a total of three channel arms in the plan view. Two of the three channel arms are located in the first plane 360A and one of the three channel arms extends into the second plane 360B. With this arrangement, the upper channel connecting element 364 can be aligned relative to the rotary valve wall 363 such that the upper inlet and outlet openings 362A of the first plane 360A are connected to the lower inlet and outlet openings 362B. Thus, fluid can flow into the double rotary spool valve arrangement 360 via the upper inlet and outlet openings 362A and out via the lower inlet and outlet openings 362B, and vice versa. One of the three channel arms thus remains unused and ends blindly / non-through at the rotary spool valve wall 363 where there are no inlet and outlet openings.

[0128] Similar to the upper channel connecting element 364, the lower channel connecting element 365 is configured in a T-shape with a total of three channel arms in the plan view. Compared to the upper channel connecting element 364, all three channel arms lie in a single plane (second plane 360B). In this arrangement, two of the three channel arms connect the two lower inlet and outlet openings 362B at a 90° angle. The third channel arm remains unused and terminates blindly at the rotary slide valve wall 363, which has no inlet or outlet openings.

[0129] Figure 6C It shows according to Figure 6BThe arrangement 360 comprises two rotary valves in different configurations. The rotary valve wall 363 includes an upper first layer 360A with upper inlet and outlet openings 362A and a lower second layer 360B with a total of three lower inlet and outlet openings 362B. Within the rotary valve wall 363 are an upper channel connecting element 364 and a lower channel connecting element 365. The upper channel connecting element 364 is configured in a plan view as a T-shape with three channel arms, two of which are located in the first plane 360A and one of which extends into the second plane 360B. Similar to the upper channel connecting element 364, the lower channel connecting element 365 is configured in a plan view as a T-shape with three channel arms. Compared to the upper channel connecting element 364, all three channel arms are located in a single plane (the second plane 360B).

[0130] In this arrangement, with Figure 6B Compared to the previous arrangement, the two channel connecting elements 364 and 365 are arranged in a 90° rotation relative to the rotary slide valve wall 363.

[0131] With this arrangement, the upper channel connecting element 364 is oriented relative to the rotary valve wall 363, such that the upper inlet and outlet opening 362A of the first layer 360A is connected to another lower inlet and outlet opening 362B, i.e., the inlet and outlet opening 362B opposite to the upper inlet and outlet opening 362A. Therefore, fluid can flow into the double rotary valve arrangement 360 via the upper inlet and outlet opening 362A and out through the other lower inlet and outlet opening 362B, and vice versa. The third channel arm remains unused here and terminates blindly at the rotary valve wall 363 where there are no inlet and outlet openings.

[0132] In this arrangement, the lower channel connecting element 365 is oriented relative to the rotary valve wall 363 such that the other two lower inlet and outlet openings 362B are connected to each other at an angle of 180°. Therefore, fluid can flow into the dual rotary valve arrangement 360 via the lower inlet and outlet openings 362B and out via the opposite lower inlet and outlet openings 362B, and vice versa. The third channel arm remains unused and terminates blindly at the rotary valve wall 363 where there are no inlet and outlet openings.

[0133] Figure 6D An alternative embodiment of the dual rotary spool arrangement 360 according to the invention is shown. This dual rotary spool arrangement 360 further includes a first layer 360A and a second layer 360B. This embodiment can also operate two rotary spools simultaneously using only one rotary spool arrangement. This also saves the additional fluid handling element 110B or additional rotary spools that must operate with an additional stator-rotor arrangement.

[0134] This dual rotary valve arrangement 360 includes the same rotary valve wall 363 as in the previous figure. The rotary valve wall 363 includes multiple inlet and outlet openings 362A, 362B, of which only one upper inlet and outlet opening 362A is located on an upper first plane 360A, while three lower inlet and outlet openings 362B are located on a lower second plane 360B. The inlet and outlet openings 362A, 362B are arranged around the entire circumference of the rotary valve wall 363, spaced 90° apart from each other.

[0135] Within the rotary valve wall 363 is a mounting element 366, which is arranged to rotate about a central axis 361. The mounting element 366 separates the internal space into a first part and a second part, defined by the radially extending rotary valve wall 363 and by two end faces that axially restrict the rotation of the rotary valve wall 363. This separation is achieved through a number of surfaces, which, due to their specific arrangement, fulfill a certain function. Figure 6B and Figure 6C The same functionality applies to the embodiments described above. The setting element 366 includes a longitudinal plane 367 arranged parallel to but spaced apart from the central axis 361. The distance of the longitudinal plane 367 from the central axis 361 depends on the diameters of the upper inflow and outflow openings 362A and 362B, since the inflow and outflow of fluid through the upper and lower inflow and outflow openings 362A and 362B should be unrestricted. Therefore, the longitudinal plane 367 must include a distance from the central axis 361 that approximately corresponds to half the diameter of the respective inflow and outflow openings 362A, 362B. The longitudinal plane 367 is continuous with an outer flat plane 368 at the front end of the rotary valve wall 363, wherein the rotary valve wall 363 defines a first plane 360A of the double rotary valve arrangement 360 having the outer flat plane 368 at its front end. The outer flat plane 368 is arranged perpendicular to the central axis 361 and radially directly adjacent to the rotary valve wall 363. Furthermore, the setting element 366 includes an inclined plane 369 that allows fluid communication at least between the upper inflow and outflow opening 362A and the lower inflow and outflow opening 362B offset by 90°. The inclined plane 369 intersects the central axis 361 and the longitudinal plane 367. Therefore, a first portion of the space is defined by a front plane that axially restricts the rotary valve wall 363 and includes an outer flat plane 368, the inclined plane 369, and the longitudinal plane 367. When the setting element 366 is incorporated into the double rotary valve arrangement 360, the first portion of the space is at least substantially above the setting element 366. Therefore, a second portion of the space is at least partially below the outer flat plane 368 and the inclined plane 369.

[0136] The element 366 can be aligned within the rotary valve wall 363 such that the upper inlet and outlet openings 362A of the first layer 360A are fluidly connected to the lower inlet and outlet openings 362B. Therefore, fluid can flow into the dual rotary valve arrangement 360 through the upper inlet and outlet openings 362A and out through the lower inlet and outlet openings 362B, and vice versa. In other words, the fluid can change planes 360A and 360B as it flows through the first portion of the space.

[0137] In this arrangement of the setting element 366, the second portion of the space below the setting element 366 is fluidly connected to two lower inlet and outlet ports 362B at a 90° angle. Therefore, from the moment the fluid enters the double rotary slide valve arrangement 360, the fluid remains in the second plane 360B and is turned 90° until it leaves the double rotary slide valve arrangement 360.

[0138] Figure 6E It shows Figure 6D The diagram shows a dual rotary valve arrangement 360 in different configurations. The rotary valve wall 363 includes an upper first layer 360A with upper inlet and outlet ports 362A and a lower second layer 360B with a total of three lower inlet and outlet ports 362B. A setting element 366 is arranged within the rotary valve wall 363. In this arrangement, with... Figure 6D Compared to the previous arrangement, the setting element 366 is arranged in a 90° rotation relative to the rotary slide valve wall 363.

[0139] The element 366 is oriented within the rotary valve wall 363 such that the upper inlet and outlet opening 362A of the first layer 360A is fluidly connected to a lower inlet and outlet opening 362B opposite to the upper inlet and outlet opening 362A. Therefore, fluid can flow into the double rotary valve arrangement 360 via the upper inlet and outlet opening 362A and out via the other lower inlet and outlet opening 362B, and vice versa.

[0140] In this arrangement of element 366, two additional lower inlet and outlet ports 362B, arranged opposite to each other, are fluidly connected to each other through a second portion of space below element 366. Figure 6D Compared to the arrangement shown, fluid flows into and out of the double rotary valve arrangement 360 in the same direction. Similarly, from the time the fluid flows into the double rotary valve arrangement 360 until it flows out of the double rotary valve arrangement 360, the fluid remains in the second plane 360B.

[0141] Figure 6FA perspective view shows a mounting element 366 having a central axis 361, an inclined plane 369, a longitudinal plane 367, and a flat plane 368. Furthermore, the mounting element 366 includes a short inflow plane 369A, which flattens the inclined plane 369 at its upper portion. The central axis 361 has an upper portion suitable for connection to a wet-running gearbox (not shown) and a lower portion suitable for supporting the mounting element 366.

[0142] Figure 6G An alternative perspective view is shown according to Figure 6F Setting element 366.

[0143] This setting element 366 is typically manufactured via injection molding. Its design is less complex than, for example, branch channel arrangements. The injection mold can be configured as a simple "on / off" mold, eliminating the need for additional side slides. This reduces the design, maintenance, and manufacturing costs of the setting element 366.

[0144] Figure 7 An exploded view of an apparatus 100 according to the invention for treating a fluid according to another embodiment is shown. The apparatus 100 includes a first housing section 200 and a second housing section 300, wherein the first housing section 200 and the second housing section 300 are configured to be adjacent to each other by a fluid-impermeable profile wall 150. The profile wall 150 is configured as a single piece. In this embodiment, the profile wall 150 is also the outer wall of the second housing section 300, thereby sharing the same side of the second housing section 300 oriented toward the first housing section 200.

[0145] The contour wall 150 includes cylindrical protrusions 152 on its side facing the first housing section 200. Stator-shaped components 210A, 210B, and 210C for generating a controllable variable magnetic field are applied to these cylindrical protrusions 152. Each cylindrical protrusion 152 protrudes into and completely fills the internal space of each arranged stator. In this embodiment, the components 210A, 210B, 210C, and 210D for generating the controllable variable magnetic field are configured as the stator of a stepper motor.

[0146] On the side of the profile wall 150 oriented toward the second housing section 300 (not shown), there are components 310A, 310B, 310C configured to be movable by a generated magnetic field from corresponding associated components 210A, 210B, 210C for generating a controllable variable magnetic field. Each component 310A, 310B, 310C configured to be movable by the generated magnetic field includes a rotor having an associated magnet (not shown). The rotor is set to rotate by the stator, thereby enabling the components 310A, 310B, 310C configured to be movable by the magnetic field to be controlled by the stator. Components 310A, 310B, 310C movable by the generated magnetic field are each associated with components for conveying and / or controlling fluid. Thus, the stator for component 210B, used to generate the controllable variable magnetic field, is assigned to a switching element 330, which is configured as a rotary slide valve. Due to the rotary slide valve, different installation spaces and different requirements can be achieved in each case using different switching strategies. The fluid can be diverted, and different ports and switching modes can be combined.

[0147] The rotating impeller 340 (not shown) is associated with each of the stators of components 210A and 210C used to generate a controllable variable magnetic field. The rotating impeller 340 is configured as an impeller and is directly integrated into the fluid circuit within the second housing section 300. Torque is generated by the stator via magnetic coupling to the rotor, thereby causing the impeller to rotate. Thus, the impeller can be used as a pump for the corresponding associated fluid circuit.

[0148] The rotors associated with components 310A, 310B, and 310C, each configured to be movable by a magnetic field, are each placed in a cylindrical protrusion 152 to receive a rotor located in the second housing section 300. In other words, the cylindrical protrusion 152 enables precise arrangement of the stator in the first housing section 200 and the rotor in the second housing section 300, thereby achieving precise allocation of the rotor and stator to each other. The cylindrical protrusion 152 thus performs a dual function: on the one hand, it allocates the rotor to the stator, and on the other hand, it provides a fluid-tight separation (which can be described as hydraulic decoupling) between the first housing section 200 and the second housing section 300.

[0149] A combination of stator-shaped components 210A, 210B, 210C arranged in the dry first housing section 200 for generating a controllable variable magnetic field, and corresponding associated components 310A, 310B, 310C movable by the generated magnetic field, each describing a fluid handling element 110A, 110B, 110C, wherein components 310A, 310B, 310C are arranged in the wet second housing section 300 and can operate across the contour wall 152 via magnetic coupling.

[0150] A stepper motor-shaped component 210D for generating a controllable variable magnetic field is associated with the first drying housing section 200. Additionally, a component movable via the generated magnetic field is associated, configured as an expansion valve 370. Compared to the fluid handling elements 110A, 110B, and 110C described above, there is no continuous fluid-impermeable contour wall between the component 210D for generating the controllable variable magnetic field and the component movable via the generated magnetic field. The latter is integrated into the housing of the expansion valve 370, and the expansion valve 370 is arranged only parallel to the other fluid handling elements 110A, 110B, and 110C on the housing section of the device, wherein the stepper motor is integrated into the drying area of ​​the first housing section 200. A total of four lateral retaining members 304 are arranged to stabilize the expansion valve 370 in the device 100.

[0151] In general, the device 100 in this embodiment has a first fluid handling element 110A configured as a fluid pump. Furthermore, the device 100 includes a second fluid handling element 110C, which also includes a fluid pump. This allows for the operation of two separate fluid circuits or allows the delivery of fluid from two separate fluid circuits. Additionally, the device 100 includes a third fluid handling element 110B, which includes a fluid valve or switching element 330. The fluid valve is configured with a rotary slide valve, and the rotary slide valve adapts the device 100 to different vehicles. Different installation spaces and different requirements of the vehicle can be accommodated, for example, by redirecting the fluid. By switching the rotary slide valve, a switch can be made from a parallel fluid circuit to a series fluid circuit. An expansion valve 370 is configured to operate a heat exchanger 380. The heat exchanger 380 is laterally fixed to the second housing section 300 by means of a flange 382.

[0152] All fluid handling elements 110A, 110B, and 110C are arranged on the device 100 such that the rotor shafts (not shown) of the fluid handling elements 110A, 110B, and 110C are arranged parallel to each other. This greatly simplifies the fabrication and assembly of the entire device 100, allowing for easy testing and replacement of additional individual components.

[0153] Multiple ports 320A, 320B, 320C, and 320D are arranged on the second housing section 300 for fluid inflow and outflow. These ports serve as customer interfaces and can be modified as needed in terms of hose diameter and corresponding location. This embodiment includes a total of four ports 320A, 320B, 320C, and 320D, which laterally discharge fluid from or laterally introduce fluid into the second housing section 300. Port 320D is used for connection to a heat exchanger 380.

[0154] Device 100 includes an electrical control unit 220, which is also arranged in the dry first housing section 200. The electrical control unit 220 is typically configured as a flat object, such as for a control circuit board. The control unit 220 is arranged above stator-shaped components 210A, 210B, 210C, 210D for generating a controllable variable magnetic field. The electrical control unit 220 is essential for controlling device 100. For example, the control unit 220 could also be arranged between the various stators within the first housing section 200, but adjacent to a fluid-impermeable profile wall 150. This would be advantageous because the electrical control unit 220 could be additionally cooled without the risk of direct contact with the fluid. Furthermore, heating could be provided using the heat loss generated during the operation of the electrical control unit 220. Alternatively, the electrical control unit 220 could also be arranged externally to device 100. This is suitable, for example, for an external customer-specific control unit connected to device 100 via an interface (e.g., via connector port 204).

[0155] The first housing section 200 includes a removable first cover element 202. This first cover element 202 simplifies access to all electronic components arranged within the first housing section 200. Therefore, direct access to dry areas and electronic components within the device 100 is possible for repair, inspection, and even testing purposes. For example, the cover element 202 can be connected to the second housing section 300 via a threaded connection. However, alternatively, a clamp or snap-fit ​​connection is equally conceivable. Additionally, the first cover element 202 includes a connector port 204 for use as an additional interface for customers. For example, the device 100 can be connected and operated via a customer's own control unit.

[0156] Therefore, the second housing section 300 also has a removable second cover element 302. This second cover element 302 can also be removed for maintenance purposes, thereby allowing direct access to all wet-operating components of the device 100. For example, defective components can be replaced without removing the entire device 100 directly from the associated vehicle. The second cover element 302 has a total of three bearings 303 configured to receive corresponding components 310A, 310B, 310C that can be moved by the generated magnetic field. For example, the lower portion of the central axis 361 (not shown) of the setting element 366 (not shown) can be received by the associated bearing 303 in the second cover element 302.

[0157] Figure 8 A cross-sectional view of a valve device 400 according to the invention is shown. The valve device 400 is part of a device 100 (not shown) for handling fluids within at least a partially electrically driven vehicle. The valve device 400 includes a valve housing 410 having at least two radially arranged port openings 420—three port openings 420 in… Figure 8 As shown in the diagram. One of the three port openings 420 can also be configured as a blind / non-obstructed port, depending on its function. Additionally, there are downwardly projecting axially arranged port openings 420 for fluid inflow and / or outflow. The valve body 430 is located within the valve housing 410 and is configured to rotate about an axial axis of rotation R. The valve body 430 has a first arcuate connecting channel 440 and a second arcuate connecting channel 442. The first arcuate connecting channel 440 connects the two radially arranged port openings 420. The second arcuate connecting channel 442 connects the radially arranged port openings 420 to the axially arranged port openings 420. The radially arranged port openings 420 form a base plane B, which is orthogonal to the axis of rotation R.

[0158] A first arcuate connecting channel 440 defines a first connecting channel plane V. The first connecting channel plane V is inclined relative to the base plane B. The two planes enclose each other at a first inclination angle α of approximately 5°. As a result, the first arcuate connecting channel 440 is configured to be spatially inclined, wherein the inlet and outlet openings of the connecting channel 440 are oriented downwards.

[0159] The valve body 430 is configured in a spherical shape and includes an upper bearing 450 and a lower bearing 450. The upper bearing 450 is directly associated with an opening in the housing cover 412. The lower bearing 450 includes a bearing ring 452, which ensures the stability of the valve body 430 within the valve housing 410. A sealing element 460 is located at the transition between the valve body 430 and each radial port opening 420.

[0160] Figure 9 Another cross-sectional view of the valve device 400 according to the invention is shown. The same features are indicated by the same reference numerals and need not be described again.

[0161] Furthermore, the second arcuate connecting channel 442 for connecting the radially arranged port opening 420 with the axially downwardly arranged port opening 420 includes an additional connecting channel 444 for connecting the second radially arranged port opening 420 with the axially arranged port opening 420. The second radially arranged port opening 420 is closed by the valve housing 410 in the shown switching position of the valve body 430.

[0162] Figure 10 A cross-sectional view of the valve body 430 is shown. The valve body 430 shown corresponds to the aforementioned... Figure 9The valve body 430 includes a second arcuate connecting channel 442 for connecting a radially arranged port opening 420 (not shown) to an axially downward arranged port opening 420 (not shown). Furthermore, the valve body 430 includes an additional connecting channel 444 for connecting the radially arranged port opening 420 to the axially arranged port opening 420. A bearing ring 452 is disposed as part of a bearing 450 on the underside of the valve body 430.

[0163] Figure 11 A perspective view of a valve body 430 according to another embodiment is shown. The valve body 430 includes a profile 470 associated with the inlet and / or outlet of a connection channel 440. The profile extends longitudinally and is orthogonal to the axis of rotation R. A bearing ring 452 is located on the underside of the valve body 430.

[0164] All features explained and illustrated in connection with the various embodiments of the invention may be provided in different combinations within the subject matter of the invention in order to achieve their advantageous effects simultaneously. The scope of protection of the invention is given by the claims and is not limited to the features explained in the specification or shown in the drawings.
