Description

Technical Field

[0001] The invention relates to a device for treating a fluid in a vehicle which is at least partially electrically driven. Background Art

[0002] Such devices are also referred to in the prior art as energy optimization modules or thermal management devices. Thermal management devices essentially perform the task of optimizing the thermal energy balance in a motor vehicle, with the aim of reducing fuel consumption and emissions, ensuring cooling of the engine at every operating point and optimizing interior comfort. Its purpose is to conduct heat flows (e.g. heating and heat dissipation) in an optimal manner in the internal combustion engine, the gearbox or the passenger compartment in order to reduce energy consumption and improve interior comfort. Heat is transferred from one object to another by means of a heat transfer medium (e.g. a coolant or air), usually by forced convection. Heat is transferred from one fluid to another via a heat exchanger (e.g. a radiator, a charge air cooler, an EGR cooler or an air conditioning condenser). The mass flow of the fluid is maintained, in particular, by a pump. A sufficient cooling air mass flow is usually ensured by the air flow, so many vehicles are equipped with an electrically driven radiator fan (if the air flow is insufficient).

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

[0004] Furthermore, DE 10 2018 102 542 A1 discloses a device for treating at least one fluid in a vehicle, in particular a vehicle that is at least partially electrically driven. The device comprises at least one first, essentially plate-shaped distribution element and at least one second distribution element arranged essentially parallel to the first distribution element, wherein the first distribution element and / or the second distribution element comprises at least one fluid treatment element at least in some areas, and wherein the first distribution element and the second distribution element comprise plastic at least in some areas, and a method for producing a device for treating at least one fluid, in particular at least one device according to the invention.

[0005] A problem with known thermal management modules is that several individual components are arranged in a dispersed manner in the motor vehicle and are connected to one another via connecting hoses, cables and control units. As a result, the connecting hoses, cables and control units are sometimes distributed over long distances and the assembly effort is high. There is also a high risk of leakage and short circuits, which affects the reliability and repair sensitivity of the entire thermal management module. In addition, there are frequent problems due to leakage, such as pressure and voltage losses. Excessive cable lengths or corrosion can also exacerbate this problem.

[0006] The present invention is therefore based on the task of specifying a thermal management module that overcomes the problems from the prior art. Summary of the invention

[0007] The solution according to the invention is to provide a device for treating a fluid in a vehicle that is at least partially electrically driven, wherein the device comprises 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 through a fluid-impermeable contour wall. The contour wall comprises a side positioned toward the first housing section and a side positioned toward the second housing section, a first fluid treatment element and a second fluid treatment element, wherein each of the first fluid treatment element and the second fluid treatment element comprises a member arranged in the first housing section for generating a controllable variable magnetic field, and a member arranged in the second housing section that can be moved by the generated magnetic field. The fluid-impermeable contour wall is continuously configured between the first fluid treatment element and the second fluid treatment element.

[0008] This leads to the technical advantage that, for example, there is only a magnetic coupling between the component for generating a controllable variable magnetic field and the component that can be moved by the generated magnetic field. The magnetic coupling acts through a fluid-impermeable contour wall and allows the component that can be moved by the generated magnetic field to be arranged to run wet in the fluid in the second housing section. On the other hand, the component for generating a controllable variable magnetic field is arranged together with the control unit in a "hydraulic decoupled", dry first housing section. The separation between the second housing section carrying water and the electronic components in the first housing section reduces the risk of leakage and short circuits. In addition, it is not necessary to use dynamic seals. Therefore, there is no heat loss due to friction, and energy efficiency is improved. In general, higher efficiency can therefore be achieved.

[0009] In the sense of the present invention, the fluid-impermeable contour wall is understood as a continuous separation layer, which is configured to be continuous without interruption at least between a component for generating a controllable variable magnetic field and a component that can be moved by the generated magnetic field. In this context, fluid impermeability means that fluid exchange cannot be performed through the contour wall. The fluid-impermeable contour wall should be understood as a continuous separation layer for accommodating several fluid treatment elements. Compared with the known elastically deformable seals based on elastomers, there is no leakage caused by the flow around them. The impermeable contour wall is understood to be like a continuous shell surface. For example, it is configured as a planar surface, wherein the protrusion is configured to arrange the fluid treatment element and rise from the planar surface. Therefore, the entire device can be configured in a box-like manner, wherein the first shell section and the second shell section are symmetrical about the planar contour wall. For example, the continuous separation layer can also be the surface of a plastic object, the surface of which carries a component that can be moved by the generated magnetic field, and can be controlled by a component for generating a controllable variable magnetic field from the outer surface of the plastic object.

[0010] According to an advantageous embodiment, it may be useful to operate the rotary slide valve of the water valve via an actuator with a gearbox in dry areas, since the force / speed ratio allows a higher efficiency here. In this case, a dynamic seal is used, which, however, is mainly subject to static loads as long as no mode switching occurs.

[0011] Fluid in the sense of the present invention may be understood as any form of cooling water, coolant or refrigerant. For example, ethylene glycol or a glycol mixture is added to a water-based fluid to lower the freezing point of the fluid. Alternatively, the fluid may be oil-based to eliminate the conductivity of the fluid. This brings the additional advantage that the battery can be cooled directly.

[0012] A means for generating a controllably variable magnetic field may be understood as any means suitable for generating a magnetic field with the aid of an electric current. The magnetic field is configured to be controllable by a current supply, which in the simplest case means at least switching the magnetic field on and off. However, it is also possible to vary the strength of the magnetic field between switching on and off. For example, an electrical coil arrangement, an electromagnet, a stepper motor, a switching magnet, a brushless motor, a claw motor or an electric linear actuator may be envisaged as such a means.

[0013] On the other hand, permanent magnets, ferromagnets or objects with rare earth-based materials are conceivable as components that can be moved by the generated magnetic field.

[0014] According to an advantageous embodiment, the means for generating a controllably variable magnetic field comprises a stator, and the means movable by the generated magnetic field comprises a rotor. Due to the rotor-stator arrangement, a torque can be generated by means of magnetic coupling through the fluid-impermeable contour wall. Alternatively, the fluid treatment element can comprise, for example, an electric motor, a coil arrangement or a switching magnet as means for generating a controllably variable magnetic field arranged in the first housing section.

[0015] According to another embodiment, the profile wall comprises at least two cylindrical projections, each of which at least substantially fills the inner space of the stator arranged in the first housing segment. This provides the technical advantage that, for example, the profile wall specifies the exact installation position of the respective stator by each of its projections. The profile wall thus has a dual function. On the one hand, the fluid impermeability which is essential for the invention, and on the other hand, the positioning of the stator in the first housing segment.

[0016] According to an additional embodiment, the cylindrical protrusion is configured to receive a rotor arranged in the second housing segment. This provides the additional advantage that, for example, each rotor arranged in the second housing segment is optimally oriented relative to the associated stator. Furthermore, the cylindrical protrusion can be used as a guide for the rotor during operation, wherein the fluid impermeability is not restricted and the separation between the second housing segment carrying water and the electronics in the first housing segment is still ensured.

[0017] According to another advantageous embodiment, the second housing segment is configured to carry a fluid and comprises at least one connection for the inflow and / or outflow of the fluid. This has technical advantages, for example, the second housing segment can be designed without an electrical interface. The focus is only on the supply, diversion and discharge of the fluid, wherein the manufacture of the second housing segment is characterized by an inexpensive material selection and a suitable connection method. For example, the second housing segment can be manufactured by means of vibration welding or mirror welding, which is problematic for thermal reasons when combined with an electronic control unit and can therefore only be implemented separately. Several ports for the inflow and / or outflow of the fluid can also be realized. The port represents a customer interface. The hose diameter, number and corresponding position of the port can vary. Depending on customer requirements, the direction of the port and the alignment (axial / radial) of the port can also be adjusted, wherein variable adjustability of the port is also conceivable.

[0018] In order to adapt the entire device as flexibly as possible to specific customer requirements, different functions can be assigned to each fluid treatment element in the device. For this purpose, at least the first fluid treatment element or the second fluid treatment element comprises a fluid pump or a fluid valve. Depending on the intended use, embodiments of the fluid treatment elements are thus implemented, wherein in each embodiment the magnetic coupling is still connected to the fluid-impermeable contour wall and the component that can be moved by the generated magnetic field is arranged to run wet in the fluid in the second housing section.

[0019] For example, the first fluid treatment element and the second fluid treatment element may include a fluid pump. For example, the first fluid treatment element and the second fluid treatment element may include a fluid valve.

[0020] According to a preferred embodiment, the rotor is associated with a member for conveying and / or controlling the fluid. Due to the magnetic coupling between the stator and the rotor, the magnets arranged on the rotor are set to rotate by the stator. In addition, different members can be arranged on the rotor itself, depending on the required function of the corresponding fluid treatment element. For example, a pump with an impeller or with a running wheel can be used to pump the fluid. In order to control or divert the fluid, for example, a rotary valve or a switch valve can be used.

[0021] According to another embodiment, at least one component comprises a switching element. This allows, for example, the technical advantage that the switching element can be configured as a rotary slide valve. This makes the device or the fluid treatment element suitable for different vehicles and different functions. Different installation spaces and different requirements of vehicle manufacturers require different switching strategies. For example, the fluid can be diverted by a rotary slide valve and a variety of ports and switching modes can be realized.

[0022] According to another embodiment, the component comprises a running wheel. This has the technical advantage that, for example, the running wheel can be directly integrated into the fluid circuit. By means of a stator-rotor connection, a pump function can thus be achieved from the rotation. For example, the running wheel is configured as an impeller.

[0023] According to an additional embodiment, a wet-running gearbox is associated with the rotor. This provides technical advantages, for example, the torque generated at the rotor can be adapted to the required function. For example, different phases can be used for transmission. The gearbox can be arranged directly in the fluid and thus in the second housing section. This eliminates the need for dynamic seals. Potentially necessary lubrication can be provided directly by the cooling water, and any heat losses due to friction are dissipated directly into the cooling fluid. As an alternative to this embodiment, it is also possible to operate the rotor without a wet-running gearbox. For example, the rotor can be sealed from the fluid by means of a seal. Thus, the rotor can be run dry.

[0024] 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 arranged outside the first housing section or inside the first housing section. It is also conceivable to operate the device with an external control unit provided by the customer, wherein an interface can be provided on the first housing section for this purpose. However, alternatively or additionally, the control unit can be arranged inside the first housing section.

[0025] Based on this, the electrical control unit is arranged in the first housing section, adjacent to the fluid-impermeable contour wall. For example, it can be provided that the electrical control unit can be effectively cooled by placing the electrical control unit against the fluid-impermeable contour wall in the first housing section. There is no risk of direct contact with the fluid when this cooling occurs, thereby avoiding short circuits. In addition, the fluid can be heated with dissipated heat. Another advantage is that the temperature difference between the low coolant temperature and the chip temperature of the power electronic device is large. For example, a temperature sensor can be arranged on one side of the electrical control unit (i.e., in a dry area) to measure the fluid temperature. The sensor will therefore be measured by the fluid-impermeable contour wall, and the evaluation of the sensor signal can be performed directly in the dry area of ​​the first housing section. According to a specific embodiment, if a faster sensor response time is required, the temperature sensor can also intersect with a sealing wall with a static seal, and therefore includes direct contact with the fluid flow.

[0026] According to an additional embodiment, the electrical control unit is arranged in the first housing section, adjacent to the fluid-impermeable contour wall between the first fluid treatment element and the second fluid treatment element. Thus, an optimal cooling capacity can be achieved. The more heat that can be removed from the electrical control unit, the higher the cooling capacity at the electrical control unit. Therefore, it is necessary to bring the majority of the electrical control unit as close as possible to the fluid flow. If the fluid-impermeable contour wall is also arranged between the first fluid treatment element and the second fluid treatment element, there is a section in the intermediate space between the first fluid treatment element and the second fluid treatment element that is suitable for arranging the electrical control unit directly in a planar manner on the contour wall. In combination with the directly adjacent fluid flow channels on the opposite sides of the contour wall (thus in the second housing section for wet operation), this leads to an optimal cooling performance.

[0027] In order to adapt the device more flexibly to customer-specific conditions, the device includes a third fluid treatment element, which includes a fluid pump or a fluid valve. This can provide technical advantages such as the ability to control additional fluid circuits. For example, in the case of a fluid valve, an additional rotary slide valve can be used. The rotary slide valve makes the device suitable for different vehicles, where different installation spaces and different requirements may, for example, require the fluid to be diverted. By switching the interface, it is possible to switch from a parallel circuit to a series circuit. For example, the fluid valve includes a double rotary slide arrangement with a first layer and a second layer. For example, this leads to the technical advantage that, for example, two switch positions can be arranged and operated simultaneously in a rotary slide valve with only one fluid treatment element. For example, no additional fluid treatment element is required, because two switch positions can be controlled with only one rotor-stator arrangement. For example, it may be necessary to supply fluid to different installation spaces on different vehicles. In order to prevent the replacement of the entire fluid treatment element, a rotary slide valve arrangement of different layers can be used. Therefore, depending on the desired purpose, different fluid channels are connected to each other without changing the entire fluid treatment element. For example, the first layer can include a valve position that allows a 90° turn, while the second layer can include a valve position that allows a straight pass or a 180° turn, i.e. a straight forward. By appropriately utilizing the dispensing ports of the rotary slide valve arrangement in the first plane or in the second plane, the desired functionality is achieved.

[0028] According to another embodiment, the device comprises a fluid treatment element in the form of 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 similar manner to other fluid treatment elements of the device. The manufacture and assembly of the device are further simplified. Based on this, the heat exchanger comprises an associated heating device. Preferably, the heating device can be integrated into the heat exchanger so that the fluid can be heated directly, which can then be used to heat the battery, the engine or the interior of the vehicle. The heat exchanger (also called a cooler) will therefore have the ability to actively heat or cool.

[0029] Such heat exchangers are usually brazed from stacked sheets. The plates are brazed in such a way that one channel of the first fluid is always in thermal contact with a channel of the second fluid in alternation. Due to the large contact area, an optimal transfer of heat is possible. For example, a thermoformed sleeve can be brazed into a package of stacked metal sheets, which can then be filled with a heating wire and insulating ceramic, similar to a conventional heating cartridge. The heating device can also be operated inductively, for example, in which an inductively heatable object is inserted and heated via a circulating induction coil. It is also conceivable to use a combined control unit, which would save additional cables and simplify module integration. Overall, such a heat exchanger saves additional hose connections and makes the device more compact.

[0030] According to a particularly preferred embodiment, the device comprises a first fluid circuit associated with a first fluid treatment element and a second fluid circuit associated with a second fluid treatment element. This makes the device particularly easy to operate. In combination with a double rotary slide valve arrangement, for example, a total of three fluid circuits with two fluid treatment elements can be operated, each fluid treatment element having two switching positions in the rotary slide valve. In combination with a series or parallel arrangement, additional functions can be provided.

[0031] According to a particular embodiment, the rotor axes of the fluid treatment elements are arranged parallel to each other. This provides the particular advantage that production and assembly in such an arrangement are particularly simple. Furthermore, individual components can be easily tested and replaced.

[0032] In order to increase the flexibility and integration of the device into a vehicle, 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 treatment element.

[0033] According to another aspect, the solution according to the invention comprises providing a device for treating a fluid in an at least partially electrically driven vehicle, wherein the device comprises a device housing, a first housing segment and a second housing segment, wherein the first housing segment and the second housing segment are configured to be adjacent to each other via a fluid-impermeable contour wall. Furthermore, the contour wall comprises a side oriented towards the first housing segment, a side oriented towards the second housing segment and at least one fluid treatment element, wherein the fluid treatment element comprises a member arranged in the first housing segment for generating a controllably variable magnetic field and a member arranged in the second housing segment movable by the generated magnetic field.

[0034] This leads to the technical advantage that, for example, there is only a magnetic coupling between the component for generating a controllable variable magnetic field and the component that can be moved by the generated magnetic field. The magnetic coupling acts through a fluid-impermeable contour wall and allows the component that can be moved by the generated magnetic field to be arranged to run wet in the fluid in the second housing section. On the other hand, the component for generating a controllable variable magnetic field is arranged together with the control unit in a "hydraulic decoupled", dry first housing section. The separation between the electronic components in the second housing section carrying water and the first housing section reduces the risk of leakage and short circuits. In addition, it is not necessary to use dynamic seals. Therefore, there is no heat loss due to friction, and energy efficiency is improved. In general, higher efficiency can therefore be achieved.

[0035] According to an advantageous further development of the invention, the means for generating a controllably variable magnetic field comprises a stator, and the means movable by the generated magnetic field comprises a rotor. Due to the rotor-stator arrangement, a torque can be generated by means of a magnetic coupling through a fluid-impermeable contour wall. Alternatively, the fluid treatment element can comprise, for example, an electric motor, a coil arrangement or a switching magnet as means for generating a controllably variable magnetic field arranged in the first housing section.

[0036] According to another embodiment, the profile wall comprises a cylindrical projection which at least substantially fills the interior of the stator arranged in the first housing segment. This has the technical advantage that, for example, the cylindrical projection of the profile wall determines the exact installation position of the stator. The profile wall thus has a dual function. On the one hand, the fluid impermeability which is essential for the invention, and on the other hand, the positioning of the stator in the first housing segment.

[0037] According to a further embodiment, the cylindrical protrusion is configured to receive a rotor arranged in the second housing segment. This has the additional advantage that, for example, the rotor arranged in the second housing segment is optimally oriented relative to the stator. Furthermore, the cylindrical protrusion can be used as a guide for the rotor during operation, wherein the fluid impermeability is not restricted and the separation between the second housing segment carrying the water and the electronics in the first housing segment is still ensured.

[0038] According to another advantageous embodiment, the second housing segment is configured to carry the fluid and comprises at least one connection for the inflow and / or outflow of the fluid. This has technical advantages, for example, the second housing segment can be designed without electrical interfaces. The focus is only on the supply, diversion and discharge of the fluid, wherein the manufacture of the second housing segment is characterized by an inexpensive material selection and a suitable connection method.

The hose diameter, the number and the corresponding position of the port can vary. Depending on customer requirements, the direction of the port can also be adjusted, wherein variable adjustability of the port is also conceivable.

[0039] In order to adapt the entire device as flexibly as possible to specific customer requirements, different functions can be assigned to each fluid treatment element in the device. For this purpose, the fluid treatment element comprises a fluid pump or a fluid valve. Depending on the intended use, embodiments of the fluid treatment element are thus implemented, wherein in each embodiment the magnetic coupling is still connected to the fluid-impermeable contour wall and the component that can be moved by the generated magnetic field is arranged to run wet in the fluid in the second housing section.

[0040] According to a preferred embodiment, the rotor is associated with a member for conveying and / or controlling the fluid. Due to the magnetic coupling between the stator and the rotor, the magnets arranged on the rotor are set to rotate by the stator. In addition, different members can be arranged on the rotor itself, depending on the required function of the corresponding fluid treatment element. For example, a pump with an impeller or with a running wheel can be used to pump the fluid. In order to control or divert the fluid, for example, a rotary valve or a switch valve can be used.

[0041] According to an alternative embodiment, the component comprises a switching element. This allows, for example, the technical advantage that the switching element can be configured as a rotary slide valve. This makes the device or the fluid treatment element adaptable to different vehicles and different functions. Different installation spaces and different requirements of vehicle manufacturers require different switching strategies.

[0042] According to an alternative embodiment, the component comprises a running wheel. This has technical advantages, for example, the running wheel can be directly integrated into the fluid circuit. By means of a stator-rotor connection, a pump function can thus be achieved from the rotation. For example, the running wheel is configured as an impeller.

[0043] According to an additional embodiment, a wet-running gearbox is associated with the rotor. This provides technical advantages, for example, the torque generated at the rotor can be adapted to the required function. For example, different phases can be used for transmission. The gearbox can be arranged directly in the fluid and thus in the second housing section. This eliminates the need for dynamic seals. Potentially necessary lubrication can be provided directly by the cooling water, and any heat losses due to friction are dissipated directly into the cooling fluid.

[0044] 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 arranged outside the first housing section or inside the first housing section. It is also conceivable to operate the device with an external control unit provided by the customer, wherein an interface can be provided on the first housing section for this purpose.

[0046] According to another embodiment, the device comprises a second fluid treatment element, which comprises a fluid pump. Thus, for example, the technical advantage can be provided that an additional fluid circuit can be controlled by the second fluid pump.

[0047] In a particularly preferred embodiment, the device comprises a third fluid treatment element, which comprises a fluid valve. The fluid valve has the function of a rotary slide valve. The rotary valve makes the device suitable for different vehicles, in which different installation spaces and different requirements may, for example, require a fluid diversion. By means of a switch interface, it is possible to switch from a parallel circuit to a series circuit.

[0048] According to a specific embodiment, the fluid valve comprises a dual rotary sliding arrangement having a first layer and a second layer.

For example, no additional fluid treatment element is required, because the two switch positions can be controlled with only one rotor-stator arrangement. For example, it may be necessary to supply fluid to different installation spaces on different vehicles. In order to avoid having to replace the entire fluid treatment element, different layers of rotary valve assemblies can be used. Therefore, depending on the desired purpose, different fluid channels are interconnected without changing the entire fluid treatment element. For example, the first layer may include a valve position that allows a 90° turn, while the second layer may include a valve position that allows a 180° turn, i.e., a straight line.

Thus, inspection or maintenance is greatly simplified.

[0053] According to an additional embodiment, the second housing section comprises a removable second cover element.

[0069] Figure 1 An exploded view of a device 100 for treating a fluid according to the invention according to a first embodiment is shown. The device 100 is intended for use in a vehicle that is at least partially electrically operated. It can therefore be used both in purely electrically operated vehicles and in hybrid vehicles.

[0070] The device 100 comprises a first housing segment 200 and a second housing segment 300, wherein the first housing segment 200 and the second housing segment 300 are configured to be adjacent to each other via a fluid-impermeable contour wall 150. The contour wall 150 is configured as a single piece. In the present embodiment, the contour wall 150 is also the outer wall of the second housing segment 300, whereby the outer wall is identical to the side of the second housing segment 300 that is oriented toward the first housing segment 200.

[0071] On the side facing the first housing segment 200, the profile wall 150 comprises a plurality of cylindrical protrusions 152. Applied to these cylindrical protrusions 152 are members (210A, 210B, 210C) in the form of stators for generating a controllable variable magnetic field. The cylindrical protrusions 152 protrude into the interior of each arranged stator and fill the interior in the following manner: a hollow cylinder is arranged on the side of the second housing segment 300, into which members 310A, 310B, 310C designed to be movable by the generated magnetic field can be inserted. The members 210A, 210B, 210C, 210D for generating a controllable variable magnetic field are configured as stators of stepper motors in the present embodiment, but they can also be configured as ordinary motors, brushless DC motors (e.g. claw motors) or solenoid valves.

[0072] On the side (not shown) of the profile wall 150 directed toward the second housing segment 300, there are components 310A, 310B, 310C, which are configured to be movable by the magnetic field generated by the corresponding associated components 210A, 210B, 210C for generating a controllable variable magnetic field. Components 310A, 310B, 310C are configured to be movable by the generated magnetic field, and they all include rotors with associated magnets. The rotor is caused to rotate by the stator, so that the components 310A, 310B, 310C configured to be movable by the magnetic field can be controlled by the stator. The components 310A, 310B, 310C that can be moved by the generated magnetic field are respectively associated with the components for conveying and / or controlling the fluid. For example, the stator of the component 210B for generating a controllable variable magnetic field is associated with a switch element 330 configured as a rotating slide. Due to the rotary slide valve, different installation spaces and different requirements can be achieved by different circuit strategies. The fluid can be turned, and different ports and switch modes can be combined.

[0073] The stators of the means 210A, 210C for generating a controllably variable magnetic field are each associated with a running wheel 340. The running wheel is configured, for example, as an impeller and is directly integrated into the fluid circuit within the second housing segment 300. Torque is generated by the stator via magnetic coupling to the rotor, which results in the rotation of the impeller. Thus, the impeller can be used as a pump for the corresponding associated fluid circuit.

[0074] The rotors associated with the members 310A, 310B, 310C configured to be movable by a magnetic field are respectively placed in the cylindrical protrusions 152 of the profile wall 150 in the second housing segment 300. In other words, the cylindrical protrusions 152 enable both a precise arrangement of the stator in the first housing segment 200 and a precise arrangement of the rotor in the second housing segment 300, thereby enabling a precise association of the rotor with the stator. In other words, the cylindrical protrusions 152 enable both a precise arrangement of the stator in the first housing segment 200 and a precise arrangement of the rotor in the second housing segment 300, thereby enabling a precise association of the rotor with the stator. Thus, the cylindrical protrusions fulfil a dual function, on the one hand the allocation of the rotor and the stator, and a fluid-tight separation between the first housing segment 200 and the second housing segment 300, which can be referred to as hydraulic decoupling.

[0075] A combination of components 210A, 210B, 210C in the form of stators for generating a controllable variable magnetic field, arranged in a dry first housing section 200, and corresponding associated components 310A, 310B, 310C, which can be moved by the generated magnetic field, arranged in a wet second housing section 300 and can operate across the contour wall 152 by magnetic coupling, each describes a fluid treatment element 110A, 110B, 110C.

[0076] An exception is a member 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 with the fluid treatment elements 110A, 110B, 110C already described, there is no continuous fluid-impermeable contour wall 150 between the member 210D for generating a controllable variable magnetic field and the member that can be moved by 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 treatment elements 110A, 110B, 110C on the housing section of the device 100, wherein the stepper motor is integrated into the dry area of ​​the first housing section 200. In order to seal the necessary opening in the fluid-impermeable contour wall 150 for the expansion valve 370 to pass therethrough, it is recommended to arrange an O-ring.

[0077] In general, in the present embodiment, the device 100 comprises a first fluid treatment element 110A configured as a fluid pump. In addition, the device 100 comprises a second fluid treatment element 110C, which also comprises a fluid pump. This allows the operation of two separate fluid circuits or allows the delivery of fluids from two separate fluid circuits. In addition, the device 100 comprises a third fluid treatment element 110B, which comprises a switching element 330 or a fluid valve. 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 achieved, for example by diverting the fluid. By switching the rotary slide valve, it is possible to switch from a parallel fluid circuit to a series fluid circuit. In addition, a proportional mixing ratio can be provided. In addition, the device 100 comprises a member 210D in the form of a stepper motor for generating a controllable variable magnetic field, wherein an expansion valve 370 is associated with the member 210D for operating a heat exchanger 380.

[0078] All fluid treatment elements (110A, 110B, 110C) are arranged on the device 100 so that the rotor axes (not shown) of the fluid treatment elements 110A, 110B, 110C are arranged parallel to each other. This significantly simplifies the production and assembly of the entire device 100, wherein additional independent components can be easily tested and replaced.

[0079] A plurality of ports 320A, 320B, 320C, 320D are arranged on the second housing section 300 for fluid inflow and / or outflow. These ports are used as customer interfaces and can be changed in terms of pipe diameter and corresponding position as required. The present embodiment includes a total of four ports 320A, 320B, 320C, 320D, which discharge fluid laterally from the second housing section 300 and introduce fluid laterally into the second housing section 300, respectively. One port 320D is used as a connection with a heat exchanger 380. The heat exchanger 380 is associated with a member 210D in the form of a stepper motor for generating a controllable variable magnetic field in the dry first housing section 200. The heat exchanger 380 is also associated with an expansion valve 370.

[0080] 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, which is usually used for example for control panels, etc. The control unit 220 is arranged above the components 210A, 210B, 210C, 210D in the form of stators for generating controllable variable magnetic fields. The electrical control unit 220 is necessary for controlling the device 100. For example, the control unit 220 can also be arranged between the various stators in the first housing section 200, but adjacent to the fluid-impermeable contour wall 150. This will be advantageous because the electrical control unit 220 can be additionally cooled without the risk of direct contact with the fluid. In addition, heating can be provided by heat losses occurring during the operation of the electrical control unit 220.

[0081] The first housing section 200 comprises a removable first cover element 202. The first cover element 202 facilitates access to all electronic devices, such as the electrical control unit 220 or the components 210A, 210B, 210C, 210D for generating a controllable variable magnetic field (which are installed in the first housing section 200). Thus, the dry area and the components of the electronic devices in the device 100 can be directly approached for maintenance, inspection or even testing purposes. In addition, the first cover element 202 comprises a connector port 204 that can be used as an additional interface for the customer. For example, the device 100 can be connected and operated with the help of the customer's own control unit.

[0082] 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 running parts of the device 100. For example, a defective component can also be replaced without having to remove the entire device 100 directly from the relevant vehicle.

[0083] As already explained, the first housing segment 200 and the second housing segment 300 are configured to be adjacent to each other via a fluid-impermeable contour wall 150. The contour wall 150 is configured as a single piece. In this embodiment, almost all fluid treatment elements 110A, 110B, 110C are arranged on the continuous fluid-impermeable contour wall 150. The continuous fluid-impermeable contour wall 150 is also the outer wall of the second housing segment 300.

[0084] Figure 2ADetailed longitudinal section of a fluid treatment element 110A of a device 100 according to the invention is shown. The device 100 comprises a first housing segment 200 and a second housing segment 300, wherein the first housing segment 200 and the second housing segment 300 are arranged adjacent to each other via a fluid-impermeable contour wall 150. The contour wall 150 is at the same time an outer wall of the second housing segment 300, whereby the outer wall is identical to the side of the second housing segment 300 which is oriented towards the first housing segment 200.

[0085] The profile wall 150 comprises a protrusion 152 on the side facing the first housing segment 200. The protrusion 152 is surrounded by a member 210A in the form of a stator for generating a controllably variable magnetic field and protrudes completely through the interior of the stator, almost completely filling it.

[0086] Furthermore, an electrical control unit 220 for controlling the device 100 is located in the first housing section 200. It is arranged above a component 210A in the form of a stator for generating a controllably variable magnetic field. The component 210A in the form of a stator for generating a controllably variable magnetic field and the electrical control unit 220 for controlling the device 100 are enclosed by a first cover element 202 and are protected from external influences, such as dust, moisture or mechanical effects.

[0087] In the second housing section 300 configured to carry the fluid, a member 310A that can be moved by the generated magnetic field is arranged. The member 310A that can be moved by the generated magnetic field includes a rotor 314 with an associated magnet. The rotor 314 is precisely inserted into the protrusion 152 of the contour wall 150, which ensures a precise alignment between the rotor 314 and the stator. The rotor 314 is set to rotate by the stator, whereby the member 310A that can be moved by the magnetic field is set to rotate and can therefore be controlled by the stator. In order to improve the function of the rotor-stator arrangement, an insulator (not shown) is arranged in the radial direction between the rotor 314 and the protrusion 152. For example, ferrite fillers are suitable for this. A running wheel 340 is arranged below the rotor 314, and the running wheel 340 can be used as a pump for conveying fluid by rotation. The running wheel 340 is located in a running wheel housing 342, wherein a fluid inflow opening 344 is located at the lower end of the running wheel housing 342. Due to the rotation of the running wheel 340 in the radial direction, the fluid thus flows into the running wheel housing 342 through the fluid inlet opening 344 and flows out through the fluid outlet opening (not shown). Therefore, the running wheel housing 342 can be incorporated into the second housing section 300 as a separate component that varies depending on the running wheel size and / or the desired pump performance. The rotor 314 includes a rotor axis 312A, and the member 310A that can be moved by the magnetic field, including the rotor 314 and the running wheel 340, is arranged rotationally symmetrically with respect to the rotor axis 312A.

[0088] Figure 2B A longitudinal cross-sectional view of an alternative embodiment of a fluid treatment element 110 of a device 100 according to the present invention is shown. This embodiment further comprises a first housing segment (not shown) and a second housing segment (not shown), wherein the first housing segment 200 and the second housing segment 300 are configured to be adjacent to each other through a fluid-impermeable contour wall 150. The contour wall 150 comprises a protrusion 152 on the side oriented toward the first housing segment 200. The protrusion 152 is surrounded by a member 210 in the form of a stator for generating a controllable variable magnetic field. The stator comprises 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.

[0089] The member movable by the generated magnetic field is arranged in the second housing section 300 configured to carry the fluid. The member movable by the generated magnetic field includes a first member 310-1 movable by the generated magnetic field and a second member 310-2 movable by the generated magnetic field.

[0090] The first component 310 - 1 that can be moved by the generated magnetic field is associated with the magnetic field of the first stator 210 - 1 , and the second component 310 - 2 that can be moved by the generated magnetic field is associated with the magnetic field of the second stator 210 - 2 .

[0091] Furthermore, the first member 310 - 1 , which is movable by the magnetic field generated by the first stator 210 - 1 , includes a first rotor 314A having associated magnets.

[0092] Thus, the second member 310 - 2 that is movable by the generated magnetic field of the second stator 210 - 2 includes a second rotor 314B having associated magnets.

[0093] The two rotors 314A, 314B are precisely inserted into the protrusion 152 of the profile wall 150 in the second housing segment 300. The first rotor 314A is associated with the first stator 210-1. The first rotor 314A is set in rotation by the first stator 210-1, whereby the first member 310-1, which can be moved by the magnetic field of the first stator 210-1, can be set in rotation and can therefore be controlled by the first stator 210-1.

[0094] The second rotor 314B is associated with the second stator 210-2. The second rotor 314B is set into rotation by the second stator 210-2, whereby the second member 310-2 movable by the magnetic field of the second stator 210-2 can be set into rotation and thus can be controlled by the second stator 210-2.

[0095] The rotor shaft 316 connects the first rotor 314A to the first running wheel 340A, and the first running wheel 340A can rotate to act as a pump to transport fluid. The first running wheel 340A is located in the running wheel housing 342A, wherein the fluid inlet opening 344A is located at the lower end of the running wheel housing 342A. Due to the rotation of the running wheel 340A in the radial direction, the fluid flows into the running wheel housing 342A through the fluid inlet opening 344A and flows out through the fluid outlet port 346A.

[0096] The second rotor 314B is connected to the second running wheel 340B via the hollow rotor shaft 317, and the second running wheel 340B can be used as a pump to transport fluid by rotation. The second running wheel 340B is located in the running wheel housing 342B, wherein the fluid flows into the running wheel housing 342B via the transversely arranged fluid inlet port 344B. The rotation of the running wheel 340B causes the fluid to flow out in the radial direction through the fluid outlet port 346B.

[0097] The first running wheel housing 342A and the second running 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 running wheel housing 342B. For example, the hollow rotor shaft 317 may be directly fixed to the separation element 348.

[0098] The first running wheel 340A can be operated by selectively controlling the first stator 210-1 by the electric control unit 220 (not shown). The second running wheel 340B can be operated independently of the first running wheel 340A by selectively controlling the second stator 210-2. Here, the rotors 314A, 314B include a common rotor axis 312, and the first member 310-1 that can be moved by the magnetic field generated by the first stator 210-1 and the second member 310-2 that can be moved by the magnetic field generated by the second stator 210-2 are both arranged rotationally symmetrically with respect to the common rotor axis 312.

[0099] This means that two different fluid pumps can be arranged and operated in one compact housing. This leads to the additional advantage that two different fluid circuits can be delivered separately from each other in the device 100. By separating the stator 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.

[0100] In order 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 contour wall 150. Similarly, an insulator (not shown) may be arranged in the radial direction between the second rotor 314B and the fluid-impermeable contour wall 150. For example, a ferrite filler is suitable for this.

[0101] Figure 2C A detailed longitudinal section of a fluid treatment element 110 of a device 100 according to the invention according to another embodiment is shown. The embodiment further comprises a first housing segment (not shown) and a second housing segment (not shown), wherein the first housing segment 200 and the second housing segment 300 are configured to be adjacent to each other through a fluid-impermeable contour wall 150. The contour wall 150 comprises a protrusion 152 on the side oriented toward the second housing segment 300. A member 210 in the form of a stator for generating a controllable variable magnetic field is inserted into the protrusion 152. The stator comprises 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.

[0102] The member movable by the generated magnetic field is arranged in the second housing section 300, which is configured to carry a fluid. The member movable by the generated magnetic field includes a first rotor 314A and a second rotor 314B.

[0103] 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 .

[0104] The two rotors 314A, 314B are arranged in the second housing segment 300 around the projection 152 of the profile wall 150. The first rotor 314A is here associated with the first stator 210-1 and is set in rotation by the first stator 210-1 and can therefore be controlled by the first stator 210-1.

[0105] The first rotor 314A is connected to a first running wheel 340A, and the first running wheel 340A can be used as a pump to transport a fluid by rotation. The first running wheel 340A is arranged radially outside the first rotor 314A and is located in a running wheel housing 342A.

[0106] Due to the rotation of the running wheel 340A in the radial direction, the fluid enters the running wheel housing 342A through the fluid inlet port 344A arranged on the side and flows out through the fluid outlet port 346A.

[0107] The second rotor 314B is associated with the second stator 210-2. The second rotor 314B is caused to rotate by the second stator 210-2 and can therefore be controlled by the second stator 210-2.

[0108] The second rotor 314B is connected to the second running wheel 340B, which can be used as a pump for pumping fluid by rotation. The second running wheel 340B is located radially outside the second rotor 314B and is arranged in the running wheel housing 342B. The fluid flows into the running wheel housing 342B from below via the fluid inlet port 344B. Due to the rotation of the running wheel 340B, the fluid is discharged in the radial direction through the fluid outlet port 346B.

[0109] The first running wheel housing 342A and the second running wheel housing 342B are configured to be separated from each other by means of a separation element 348. For example, the separation element 348 is arranged radially outward on a projection 152 of the contour wall 150, and the projection 152 includes a retainer formed for this purpose.

[0110] The first running wheel 340A can be operated by selectively controlling the first stator 210-1 by the electrical control unit 220 (not shown). The second running wheel 340B can be operated independently of the first running wheel 340A by selectively controlling the second stator 210-2. Here, the rotors 314A, 314B include a common rotor axis 312, and both the first stator 210-1 and the second stator 210-2 and the first running wheel 340A and the second running wheel 340B are arranged rotationally symmetrically with respect to the common rotor axis 312.

[0111] This means that two different fluid pumps can be arranged and operated in one compact housing. This leads to the additional advantage that two different fluid circuits can be delivered separately from each other in the device 100. By separating the stator 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 and different operating modes can be followed in separate fluid circuits without taking into account any dependencies or influences between the fluid circuits. Figure 2B Compared to the embodiment of the embodiment of the present invention, the fluid treatment element 110 of this embodiment requires significantly less axial installation space. This is due to the shape of the outer rotor. The stator is arranged inside the rotor and the associated running wheel is also located radially outside the rotor. This significantly increases the outer diameter of this embodiment of the fluid treatment element, thereby providing a higher overall running smoothness and greater tolerance to pressure waves. On the other hand, the internal stator can be configured smaller, thereby reducing manufacturing costs. In another embodiment, it is also conceivable to realize an outer rotor arrangement with only one stator and only one associated rotor.

[0112] To improve the function of the device 100, an insulator (not shown) may be arranged between the first rotor 314A and the fluid-impermeable contour wall 150. Similarly, an insulator (not shown) may be arranged between the second rotor 314B and the fluid-impermeable contour wall 150. For example, ferrite fillers are suitable for this.

[0113] Figure 2D A detailed longitudinal section of a device according to the invention according to another embodiment is shown. The device comprises a first fluid treatment element in the form of a pump device 400 and a second fluid treatment element in the form of a pump device 400. A fluid-impermeable contour wall 150 is continuously arranged between the first fluid treatment element and the second fluid treatment element. An electrical control unit 220 is arranged at a planar portion of the fluid-impermeable contour wall 150. The electrical control unit 220 is arranged adjacent to the fluid-impermeable contour wall 150 in the first housing section 200 to provide optimal cooling performance at the electrical control unit 220. The more heat that can be removed from the electrical control unit 200, the higher the cooling capacity at the electrical control unit 220. Therefore, it is necessary to make the main part of the electrical control unit 220 as close as possible to the fluid flow directly below the contour wall 150 in the second housing section. The electrical control unit 220 is attached to the contour wall 150 via a fastening element 222. For example, the fastening element can be made of a special conductive material. Alternatively, the electrical control unit 220 can be directly attached to the contour wall 150 without using a fastening element 222. The fluid treatment element is not limited to a specific embodiment in the form of a pumping device 400. Alternatively or additionally, the fluid treatment element can also be arranged as a valve, a rotary slide valve or an expansion valve in any conceivable combination. Here, the device can also include more than two fluid treatment elements. For example, the device can include three fluid treatment elements, two of which are configured as pump devices and one fluid treatment element is configured as a rotary slide valve or a valve device. In this case, the fluid-impermeable contour wall 150 will be continuously arranged between the first fluid treatment element, the second fluid treatment element and the third fluid treatment element.

[0114] The two pump devices 400 each include a fixed shaft 403 extending within the second housing section 300 (not shown), through which the fluid flows starting from the cylindrical protrusion 152, through the first rotor 314A, the second rotor 314B, the second running wheel 340B and the first running wheel 340A, and ends at the running wheel housing 342A. The fixed shaft 403 is surrounded by a first hollow shaft 405, which supports the first rotor 314A and allows torque to be transmitted from the first rotor 314A to the first running wheel 340A.

[0115] In addition, the first hollow shaft 405 is surrounded by a second hollow shaft 407. The second hollow shaft 407 supports the second rotor 314B and is configured to transmit the torque of the second rotor 314B to the second running wheel 340B. The second hollow shaft 407 is supported in a fluid dynamic seal 408, which is arranged between the first rotor 314A and the second rotor 314B. Therefore, the fluid dynamic seal 408 has a dual function of sealing the first rotor 314A relative to the second rotor 314B and supporting the second hollow shaft 407.

[0116] The first running wheel 340A is located in a running wheel housing 342A. Fluid flows into the running wheel housing 342A from below through a fluid inlet port 344A. Due to the rotation of the running wheel 340A, the fluid flows out in a radial direction through a fluid outflow port 346A.

[0117] The second running wheel 340B is located within a running wheel housing 342B, wherein fluid flows into the running wheel housing 342B through a laterally arranged fluid inlet port 344B. The rotation of the running wheel 340B causes the fluid to flow out in a radial direction through a fluid outlet port 346B.

[0118] The separator 348 is disposed between the running wheel housing 342B and the running wheel housing 342A to separate the first fluid circuit and the second fluid circuit.

[0119] The separator element 348 comprises a fluid inlet port 344B which is arranged transversely and through which the fluid flows into the running wheel housing 342B. Here, the fluid is turned inside the separator element 348 and flows from below into the running wheel housing 342B via the axial discharge opening 349. The flow from below is significantly more efficient for the performance of the running wheel 340B, thereby improving the pumping device 400 and thus the device 100 as a whole. The axial discharge opening 349 extends radially inwardly, thereby allowing the fluid to flow from below into the running wheel housing 342B even more efficiently and then be transported radially outward from the running wheel 340B.

[0120] In the present embodiment, the first running wheel 340A and the second running wheel 340B are arranged in the same direction relative to each other. An opposite arrangement is also conceivable. The first running wheel 340A and the second running wheel 340B have the same geometric shape.

[0121] The first running wheel 340A can be operated by selectively controlling the first stator 210-1 by the electric control unit 220 (not shown). The second running wheel 340B can be operated independently of the first running wheel 340A by selectively controlling the second stator 210-2. Here, the rotors 314A, 314B include a common rotor axis 312, and the first member movable by the magnetic field generated by the first stator 210-1 and the second member movable by the magnetic field generated by the second stator 210-2 are both arranged rotationally symmetrically with respect to the common rotor axis 312.

[0122] This embodiment also has the advantage that two different fluid pumps can be arranged and operated in one compact housing. This leads to the further advantage that two different fluid circuits can be delivered separately from each other in the device 100. By separating the stator 210 into a first stator 210-1 and a second stator 210-2, the two pumps can be controlled at different and distinct speeds. Thus, a high degree of flexibility is provided and different operating modes can be pursued in separate fluid circuits without envisaging any dependencies or influences between the fluid circuits.

[0123] An insulator (not shown) may be arranged in the radial direction between the first rotor 314A and the fluid-impermeable contour wall 150. Correspondingly, an insulator (not shown) may be arranged in the radial direction between the second rotor 314B and the fluid-impermeable contour wall 150. For example, a ferrite filler is suitable for this purpose.

[0124] Figure 3 A longitudinal cross-sectional view of a fluid treatment element 110A of a device 100 according to the invention is shown. A member 210A in the form of a stator for generating a controllable variable magnetic field is arranged in a first housing section (not shown). Separated from the contour wall (not shown) and therefore in an adjacent second housing section 300 (not shown), a member 310A in the form of a rotor 314 configured to be movable by a magnetic field is arranged. The rotor 314 is surrounded by an insulator (not shown) in the radial direction. The rotor 314 also includes two bearings 313, which are configured to accommodate the rotor axis. A running wheel 340 for the radial outflow of fluid is located in the lower section of the rotor 314.

[0125] In the perspective view, below the running wheel 340 is a running wheel housing 342. The running wheel housing 342 shows a fluid inlet port 344, which is centrally arranged in the base piece of the running wheel housing 342. In addition, the running wheel housing 342 includes a fluid outlet port 346 arranged in the side wall. Due to the rotation of the running wheel 340 in the radial direction, the fluid flows into the running wheel housing 342 via the fluid inlet port 344 and flows out via the fluid outlet port 346. This generates a pumping action of the fluid treatment element 110A.

[0126] Figure 4 A detailed longitudinal section of another fluid treatment element 110B of the device 100 according to the invention is shown. The device 100 comprises a first housing segment 200 and a second housing segment 300, wherein the first housing segment 200 and the second housing segment 300 are arranged adjacent to each other via a fluid-impermeable contour wall 150. The contour wall 150 is also an outer wall of the second housing segment 300, whereby the outer wall is identical to the side of the second housing segment 300 which is oriented towards the first housing segment 200.

[0127] The profile wall 150 comprises a protrusion 152 on the side facing the first housing segment 200. The protrusion 152 is surrounded by a member 210B in the form of a stator for generating a controllably variable magnetic field and the protrusion 152 completely protrudes through the interior of the stator, almost completely filling it.

[0128] Furthermore, an electrical control unit 220 for controlling the device 100 is located within the first housing section 200 and is arranged above a component 210B in the form of a stator for generating a controllably variable magnetic field. The component 210B in the form of a stator for generating a controllably variable magnetic field and the electrical control unit 220 for controlling the device 100 are enclosed by the first cover element 202 and are protected from external influences, such as dust, moisture or mechanical effects.

[0129] In the second housing section 300 configured to carry the fluid, a member 310B that can be moved by the generated magnetic field is arranged. The member 310B that can be moved by the generated magnetic field includes a rotor 314 with an associated magnet. The rotor 314 is precisely inserted into the protrusion 152 of the contour wall 150, which ensures accurate alignment between the rotor 314 and the stator. The rotor 314 is caused to rotate by the stator, whereby the member 310B that can be moved by the magnetic field can be caused to rotate and thus can be controlled by the stator. In order to improve the function of the rotor-stator arrangement, an insulator (not shown) is arranged in the radial direction between the rotor 314 and the protrusion 152. For example, a ferrite filler is suitable for this. The switch element 330 is arranged below the rotor 314. The switch element can be configured as a rotary slide valve, whereby the fluid can be diverted depending on the specific position of the rotary slide valve. The diversion of the fluid allows a variety of ports and switch modes in the device 100. This makes the device 100 or the fluid treatment element 110B suitable for different vehicles and corresponding required functions. A port 320B is arranged transversely to the switching element 330, which port is configured for inflow and / or outflow of fluid. The fluid treatment element 110B comprises a rotor axis 312B, with respect to which the member 310B movable by a magnetic field, the rotor 314 and the switching element 330 are arranged rotationally symmetrically.

[0130] Figure 5 A schematic diagram of a wet-running gearbox 350 of a device 100 according to the invention is shown. The wet-running gearbox 350 comprises a drive element 352 which 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 couples an associated gear stage 358. A rotary slide opening 359 is located directly at the gear stage 358. In the assembled state, an output element of a rotary slide (not shown) protrudes through the rotary slide opening 359 and directly engages a gear stage 358 in the wet-running gearbox 350. This allows the precise position of a switching element 330, which is configured as a rotary slide, to be controlled. Due to the universal self-locking of the wet-running gearbox 350, no force (magnetic or electric) is required to keep the rotary slide in place. This brings considerable advantages for proportional operation, for example. With this wet-running gearbox 350, any number of gear stages 358 can be coupled to ultimately determine the position of the coupled switching element 330 based on the stator controlled by the electrical control unit 220. The wet gearbox 350 is arranged directly in the fluid and thus in the second housing section 300. This means that no dynamic seals are required. The necessary lubrication of the wet-running gearbox 350 takes place directly via the cooling fluid and the heat losses due to friction are dissipated directly into the cooling fluid.

[0131] FIG. 6A to FIG. 6G Several schematic diagrams of a double rotary slide valve arrangement 360 of a device 100 according to the invention are shown. Simple rotary slide valve arrangements include so-called 2x90° deflections. These 2x90° deflections include the disadvantage that the channels cannot be connected to each other across two different planes. The double rotary slide valve arrangement 360 according to the invention includes a first layer 360A and a second layer 360B. The advantage of this double rotary slide valve arrangement 360 is that two rotary slide valves can be operated simultaneously with only one rotary slide valve arrangement. This saves additional fluid treatment elements 110B or additional rotary slide valves that must be operated with an additional stator-rotor arrangement.

[0132] Fig. 6A A schematic diagram of a rotary slide valve wall 363 of a double rotary slide valve arrangement 360 is shown. The rotary slide valve wall 363 is part of a housing that accommodates the rotary slide valves - in this embodiment, there are upper channel connecting elements 364 and lower channel connecting elements 365. The rotary valve wall 363 includes a plurality of inlet openings 362A and outlet openings 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 around the entire circumference of the rotary valve wall 363 at a spacing of 90° from each other.

[0133] Figure 6B360 is a schematic diagram of a dual rotary slide valve arrangement 360. The rotary slide valve wall 363 comprises an upper first layer 360A with an upper inlet and outlet opening 362A and a lower second layer 360B with a total of three lower inlet and outlet openings 362B. An upper channel connection element 364 and a lower channel connection element 365 are arranged in the rotary slide valve wall 363. The two channel connection elements 364, 365 are arranged to be rotatable relative to the rotary slide valve wall 363. However, the upper channel connection element 364 and the lower channel connection element 365 cannot rotate relative to each other. Therefore, they are configured with a common channel connection element.

[0134] The upper channel connecting element 364 is configured as a T-shape with a total of three channel arms in a 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. By this arrangement, the upper channel connecting element 364 can be aligned with respect to the rotary valve wall 363 so that the upper inlet and outlet opening 362A of the first plane 360A is connected with the lower inlet and outlet opening 362B. Therefore, fluid can flow into the double rotary slide valve arrangement 360 via the upper inflow and outflow opening 362A and flow out from the lower inflow and outflow opening 362B, and vice versa. One of the three channel arms therefore remains unused and ends blindly / incommunicably at the rotary slide valve wall 363 without inflow and outflow opening.

[0135] Similar to the upper channel connecting element 364, the lower channel connecting element 365 is configured as a T-shape with a total of three channel arms in a plan view. Compared with the upper channel connecting element 364, all three channel arms are located in a plane (second plane 360B). In this arrangement, two of the three channel arms connect two lower inlet and outlet openings 362B at an angle of 90 °. The third channel arm remains unused and ends blindly at the rotary slide valve wall 363 without inflow and outflow openings.

[0136] Figure 6C Shown according to Figure 6BThe double rotary slide valve arrangement 360 in different arrangements. The rotary slide valve wall 363 includes an upper first layer 360A with an upper inlet and outlet opening 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 arranged in the rotary slide valve wall 363. The upper channel connecting element 364 is configured as a T-shape with three channel arms in a plan view, wherein 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. Similar to the upper channel connecting element 364, the lower channel connecting element 365 is configured as a T-shape with three channel arms in a plan view. Compared with the upper channel connecting element 364, all three channel arms are located in one plane (the second plane 360B).

[0137] In this arrangement, Figure 6B Compared to the arrangement in , the two channel connecting elements 364 , 365 are arranged rotated 90° relative to the rotary slide valve wall 363 .

[0138] By this arrangement, the upper channel connecting element 364 is oriented relative to the rotary slide valve wall 363 so that the upper inflow and outflow opening 362A of the first layer 360A is connected to the other lower inflow and outflow opening 362B, that is, connected to the inflow and outflow opening 362B opposite to the upper inflow and outflow opening 362A. Therefore, the fluid can flow into the double rotary slide valve arrangement 360 via the upper inflow and outflow opening 362A and flow out from the other lower inflow and outflow opening 362B, and vice versa. The third channel arm remains unused and ends blindly at the rotary slide valve wall 363 without inflow and outflow openings.

[0139] In the present arrangement, the lower channel connecting element 365 is oriented relative to the rotary slide valve wall 363 so that the other two lower inflow and outflow openings 362B are connected to each other at an angle of 180°. Thus, fluid can flow into the double rotary slide valve arrangement 360 via the lower inflow and outflow openings 362B and out of the opposite lower inflow and outflow openings 362B, and vice versa. The third channel arm remains unused and ends blindly at the rotary slide valve wall 363 without inflow and outflow openings.

[0140] Fig.6D An alternative embodiment of a dual rotary slide valve arrangement 360 according to the invention is shown. This dual rotary slide valve arrangement 360 also comprises a first layer 360A and a second layer 360B. This embodiment also allows the simultaneous operation of two rotary slide valves with only one rotary slide valve arrangement. This also saves an additional fluid treatment element 110B or an additional rotary slide valve that must be operated with an additional stator-rotor arrangement.

[0141] This double rotary slide valve arrangement 360 comprises the same rotary slide valve wall 363 as in the previous figure. The rotary slide valve wall 363 comprises a plurality of inlet and outlet openings 362A, 362B, of which only one upper inlet and outlet opening 362A is located on the upper first plane 360A, and three lower inlet and outlet openings 362B are located on the lower second plane 360B. The inlet and outlet openings 362A, 362B are arranged around the entire circumference of the rotary slide valve wall 363, at a spacing of 90° from each other.

[0142] There is a setting element 366 in the rotary slide valve wall 363, which is arranged to rotate around the central axis 361. The setting element 366 separates the inner space, which is defined by the rotary slide valve wall 363 in the radial direction and by two end faces that axially limit the rotary slide valve wall 363, into a first part space and a second part space. This separation is achieved by several surfaces, which perform the same functions as the first part space due to their specific arrangement. Figure 6B and Figure 6C The same function as in the case of the embodiment ... In addition, the setting element 366 comprises an inclined plane 369, which allows fluid communication between at least 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, the first partial space is defined by the front plane, which axially limits the rotary slide valve wall 363 and contains the outer flat plane 368, the inclined plane 369 and the longitudinal plane 367. When the setting element 366 is brought into the double rotary slide valve arrangement 360, the first partial space can be said to be at least mostly located above the setting element 366. When the setting element 366 is brought into the double rotary slide valve arrangement 360, the first partial space can be said to be at least mostly located above the setting element 366. Therefore, the second partial space is at least partially below the outer flat plane 368 and the inclined plane 369.

[0143] The arrangement element 366 can be aligned in the rotary slide valve wall 363 so that the upper inlet and outlet opening 362A of the first layer 360A is fluidically connected to the lower inlet and outlet opening 362B. Thus, the fluid can flow into the double rotary slide valve arrangement 360 through the upper inlet and outlet opening 362A and out of the lower inlet and outlet opening 362B, and vice versa. In other words, the fluid can change the plane 360A, 360B when it flows through the first partial space.

[0144] In this arrangement of the setting element 366, the second portion of the space below the setting element 366 fluidly connects the two lower inlet and outlet ports 362B at a 90° angle. Thus, from the time the fluid enters the dual rotary slide valve arrangement 360, the fluid remains in the second plane 360B, being turned 90°, until it leaves the dual rotary slide valve arrangement 360.

[0145] Fig. 6E Shows Fig.6D 360 in a different configuration. The rotary slide 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 in the rotary slide valve wall 363. In this arrangement, Fig.6D Compared to the arrangement of FIG. 3 , the setting element 366 is in a 90° rotated arrangement relative to the rotary slide valve wall 363 .

[0146] The arrangement element 366 is oriented in the rotary slide valve wall 363 so that the upper inlet and outlet openings 362A of the first layer 360A are fluidically connected to another lower inlet and outlet opening 362B opposite the upper inlet and outlet openings 362A. Thus, fluid can flow into the dual rotary slide valve arrangement 360 via the upper inlet and outlet openings 362A and out of the other lower inlet and outlet openings 362B, and vice versa.

[0147] In this arrangement of the setting element 366, the other two lower inlet and outlet ports 362B arranged opposite to each other are fluidically connected to each other through the second partial space below the setting element 366. Fig.6D Compared to the arrangement shown, fluid flows into and out of the dual rotary spool valve arrangement 360 in the same direction. Likewise, from the time the fluid flows into the dual rotary spool valve arrangement 360 until it flows out of the dual rotary spool valve arrangement 360, the fluid remains in the second plane 360B.

[0148] Fig. 6FThe setting element 366 is shown in a perspective view with a central axis 361, an inclined plane 369, a longitudinal plane 367 and a flat plane 368. In addition, the setting element 366 comprises a short inflow plane 369A, which in the upper part flattens the inclined plane 369. The central axis 361 has an upper part suitable for connection to a wet-running gearbox (not shown), and a lower part suitable for supporting the setting element 366.

[0149] Figure 6G An alternative perspective view is shown according to Fig. 6F Setting element 366.

[0150] This arrangement element 366 is usually manufactured by injection molding. It is not as complicated in design as, for example, the branch channel arrangement. 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 arrangement element 366.

[0151] Figure 7 An exploded view of a device 100 for treating a fluid according to another embodiment of the invention is shown. The device 100 comprises a first housing segment 200 and a second housing segment 300, wherein the first housing segment 200 and the second housing segment 300 are arranged adjacent to each other via a fluid-impermeable contour wall 150. The contour wall 150 is configured as a single piece. In this embodiment, the contour wall 150 is also the outer wall of the second housing segment 300, whereby the outer wall is identical to the side of the second housing segment 300 that is oriented toward the first housing segment 200.

[0152] The profile wall 150 includes a cylindrical protrusion 152 on the side facing the first housing segment 200. Components 210A, 210B, 210C in the form of stators for generating a controllable variable magnetic field are applied to these cylindrical protrusions 152. The cylindrical protrusions 152 each protrude into the inner space of each arranged stator and completely fill the inner space. In the present embodiment, the components 210A, 210B, 210C, 210D for generating a controllable variable magnetic field are configured as stators of stepper motors.

[0153] On the side (not shown) of the profile wall 150 oriented toward the second housing segment 300, there are components 310A, 310B, 310C configured to be movable by the generated magnetic field of the corresponding associated components 210A, 210B, 210C for generating a controllable variable magnetic field. Each of the components 310A, 310B, 310C configured to be movable by the generated magnetic field includes a rotor with an associated magnet (not shown). The rotor is set to rotate by the stator, whereby the components 310A, 310B, 310C configured to be movable by the magnetic field can be controlled by the stator. The components 310A, 310B, 310C that can be movable by the generated magnetic field are each associated with a component for conveying and / or controlling a fluid. Therefore, the stator of the component 210B for generating a 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 realized in each case with different switching strategies. Fluids can be diverted and different ports and switch patterns can be combined.

[0154] A running wheel 340 (not shown) is associated with each of the stators of the means 210A, 210C for generating a controllable variable magnetic field. The running wheel 340 is configured as an impeller and is directly integrated into the fluid circuit within the second housing segment 300. Torque is generated by the stator via magnetic coupling to the rotor, resulting in the rotation of the impeller. Therefore, the impeller can be used as a pump for the corresponding associated fluid circuit.

[0155] The rotors associated with the components 310A, 310B, 310C and configured to be movable by a magnetic field are each placed in a cylindrical protrusion 152 for receiving a rotor located in the second housing segment 300. In other words, the cylindrical protrusion 152 enables a precise arrangement of the stator in the first housing segment 200 and a precise arrangement of the rotor in the second housing segment 300, thereby achieving a precise assignment of the rotor and the stator to each other. The cylindrical protrusion 152 thus performs a dual function of allocating the rotor to the stator on the one hand and providing a fluid-tight separation (which can be described as a hydraulic decoupling) between the first housing segment 200 and the second housing segment 300 on the other hand.

[0156] A combination of components 210A, 210B, 210C in the form of stators for generating a controllable variable magnetic field arranged in a dry first housing section 200, and corresponding associated components 310A, 310B, 310C that can be moved by the generated magnetic field, each describing a fluid processing element 110A, 110B, 110C, wherein the components 310A, 310B, 310C are arranged in a wet second housing section 300 and can operate across the contour wall 152 by magnetic coupling.

[0157] A member 210D in the form of a stepper motor for generating a controllable variable magnetic field is associated with the dry first housing section 200. In addition, a member movable by the generated magnetic field is associated, which member is configured in the form of an expansion valve 370. Compared with the above-mentioned fluid treatment elements 110A, 110B, 110C, there is no continuous fluid-impermeable contour wall between the member 210D for generating a controllable variable magnetic field and the member movable by 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 treatment elements 110A, 110B, 110C on the housing section of the device, wherein the stepper motor is integrated into the dry area of ​​the first housing section 200. A total of four transverse retaining members 304 are arranged to stabilize the expansion valve 370 in the device 100.

[0158] In general, the device 100 in this embodiment has a first fluid treatment element 110A configured as a fluid pump. In addition, the device 100 includes a second fluid treatment element 110C, which also includes a fluid pump. This allows the operation of two separate fluid circuits or allows the conveying of fluids from two separate fluid circuits. In addition, the device 100 includes a third fluid treatment 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 makes the device 100 suitable for different vehicles. Different installation spaces and different requirements of the vehicle can be implemented, for example by diverting the fluid. By switching the rotary slide valve, it is possible to switch from a parallel fluid circuit to a series fluid circuit. The 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.

[0159] All fluid treatment elements 110A, 110B, 110C are arranged on the device 100 such that the rotor axes (not shown) of the fluid treatment elements 110A, 110B, 110C are arranged parallel to each other. This greatly simplifies the production and assembly of the entire device 100, wherein additional individual components can be easily tested and replaced.

[0160] A plurality of ports 320A, 320B, 320C, 320D are arranged on the second housing section 300 for fluid inflow and outflow. These ports serve as customer interfaces and can be modified in hose diameter and corresponding positions as required. The present embodiment includes a total of four ports 320A, 320B, 320C, 320D that laterally discharge fluid from the second housing section 300 or laterally introduce fluid into the second housing section 300. Port 320D is used to connect to a heat exchanger 380.

[0161] The 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 generally configured as a flat object, such as for controlling a circuit board, etc. The control unit 220 is arranged above the components 210A, 210B, 210C, 210D formed as stators for generating a controllable variable magnetic field. The electrical control unit 220 is necessary for controlling the device 100. For example, the control unit 220 can also be arranged between the stators in the first housing section 200, but adjacent to the fluid-impermeable contour wall 150. This will be advantageous because the electrical control unit 220 can be additionally cooled without the risk of direct contact with the fluid. In addition, heating can be provided by heat loss generated during the operation of the electrical control unit 220. Alternatively, the electrical control unit 220 can also be arranged outside the device 100. For example, this is applicable to an external customer-specific control unit connected to the device 100 via an interface (e.g., via a connector port 204).

[0162] The first housing section 200 comprises a removable first cover element 202. This first cover element 202 simplifies access to all electronic devices arranged in the first housing section 200. Thus, dry areas and components of the electronic devices in the device 100 can be directly accessed for maintenance, inspection or even testing purposes. For example, the cover element 202 can be connected to the second housing section 300 by means of a threaded connection. However, alternatively, a clamp or a snap connection is also conceivable. In addition, the first cover element 202 comprises a connector port 204 for use as an additional interface for the customer. For example, the device 100 can be connected and operated by means of a customer's own control unit.

[0163] 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 running parts of the device 100. For example, a defective component can also be replaced without having to remove the entire device 100 directly from the relevant vehicle. The second cover element 302 has a total of three bearings 303, which are configured to receive corresponding members 310A, 310B, 310C that can be moved by the generated magnetic field. For example, the lower part 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.

[0164] All features explained and shown in conjunction with the various embodiments of the present invention can be provided in different combinations in the subject matter according to the present invention in order to achieve their advantageous effects at the same time. The scope of protection of the present invention is given by the claims and is not limited by the features explained in the description or shown in the drawings.
