Description

[0001] Valve unit and fluid line system

[0002] The invention relates to a valve unit for a fluid line system and a fluid line system.

[0003] Fluid line systems are particularly used in electric vehicles. Electric vehicles typically have a thermal management system that can adjust or regulate the temperature of various components. Cooling fluids, such as coolants or refrigerants, are used for this purpose and can be distributed through the fluid line system.

[0004] For example, the temperature of an electric vehicle's battery typically needs to be controlled and / or regulated. To ensure optimal performance and service life, its operating temperature and corresponding temperature ranges typically need to be precisely monitored and regulated.

[0005] In addition to the battery, other components may also need to be cooled, or at least their temperature monitored, controlled, adjusted, or regulated. For example, electric motors and power electronics generate heat during operation and must be cooled accordingly to prevent overheating and performance degradation. Cooling of chargers and DC-DC converters may also be required. Chargers and DC-DC converters convert energy for the battery and other electrical systems and also generate heat that must be dissipated to ensure efficient performance.

[0006] Furthermore, interior air conditioning, for example, of a vehicle cabin or vehicle interior, may be desirable. In particular, adjusting heating, cooling, and / or ventilation may be necessary to ensure occupant comfort.

[0007] This results in a large number of components whose fluid supply must be regulated. A fluid distribution system and a valve unit for an electric vehicle are known, for example, from EP 3 746 322 Bi. However, the valve unit disclosed therein only has limited flexibility, so that a comparatively large number of valve units and corresponding feed pumps and fluid channels are required. This makes the fluid distribution system more complex and has comparatively large dimensions. The valve unit is also limited in the number of different flow paths or fluidic connections, and thus in the number of fluid channels that can be connected and / or selected. This results in comparatively high equipment expenditure and a comparatively large amount of space is required for installation, e.g. in an electric vehicle.

[0008] The object of the present invention is to overcome these disadvantages. This object is achieved by a valve unit according to claim 1 and a fluid distribution system according to claim 41. The respective dependent subclaims relate to preferred embodiments.

[0009] A first aspect of the invention relates to a valve unit for a fluid distribution system, in particular for a fluid distribution system of an electric vehicle, wherein the valve unit has a plurality of openings through which a fluid can enter or exit the valve unit, wherein the valve unit has a rotatable valve disc with a valve disc line system and at least one further rotatable valve disc with a further valve disc line system, wherein the valve disc is designed such that, in a first rotational position of the valve disc and / or the further valve disc, a first group of openings, preferably a first pair of openings, is fluidically connected via the valve disc line system and / or the further valve disc line system, and in a second rotational position of the valve disc and / or the further valve disc, a second group of openings, preferably a second pair of openings,is fluidly connected via the valve disc line system and / or the further valve disc line system, wherein at least one opening of the second group is different from an opening of the first group.,

[0010] The valve disc and the further valve disc, and / or the valve disc line system and the further valve disc line system, can thus form an adjustable line system through the valve unit.

[0011] The valve unit according to the invention thus allows flexible switching between different flow paths. Because a fluidic connection between two (or more) openings can be established or broken by rotating the valve disc and / or the further valve disc, it is also possible to switch very quickly between different fluidic connections and / or to establish or break a specific fluidic connection very quickly. Because the valve disc and the further valve disc, and / or the valve disc line system and the further valve disc line system, form an adjustable line system through the valve unit, a suitable selection of the number of valve discs orfurther valve discs and / or through suitable design of the valve disc line system and the further valve disc line system(s), a very flexible flow guidance and combination of possible fluidic connections can be provided.

[0012] "Fluidic connection" can mean that a fluid can be transported, conveyed, and / or guided between the respective fluidically connected components, devices, elements, or the like. A "flow path" can correspond to a fluidic connection between at least two openings, which can be fluidically connected to one another at a specific rotational position of the valve disc and a specific rotational position of the other valve disc.

[0013] The fluid can be, for example, liquid and / or gaseous. The fluid can be or comprise a coolant and / or a refrigerant. The fluid can be or comprise one or more of water, air, glycol, mineral oil, or cooling oil. The fluid can comprise a synthetic coolant, which can be, for example, silicone-based, glycol-based, and / or polyalkylene glycol-based.

[0014] In some embodiments, the valve unit may have exactly one additional valve disc. For example, an additional valve disc may be a second valve disc.

[0015] In some embodiments, the valve unit may have two or more additional valve discs. For example, a second and a third valve disc may be provided, and / or at least one additional valve disc may comprise and / or correspond to at least a second and / or a third valve disc. The present disclosure also encompasses embodiments with two or more additional valve discs. If the valve unit has two or more additional valve discs, these may include some, several, or all of the features, functions, and advantages of the valve disc and / or additional valve disc. “Additional valve disc” may also mean a plurality of additional valve discs. “Additional valve disc” may also mean “at least one of the additional valve discs.” It may be provided that the rotational position of the valve disc does not necessarily have to coincide with and / or correspond to the rotational position of the additional valve disc.For example, with respect to a reference angle and / or a reference rotational position, the valve disc can be rotated by an angle so that it can be in its first rotational position. For example, with respect to a reference angle and / or a reference rotational position, the further valve disc can be rotated by a second angle so that it can be in its first rotational position. The first angle does not necessarily have to be the same as the first angle. For example, with respect to a reference angle and / or a reference rotational position, the valve disc can be rotated by a third angle so that it can be in its second rotational position. For example, with respect to a reference angle and / or a reference rotational position, the further valve disc can be rotated by a fourth angle so that it can be in its first rotational position. The third angle does not necessarily have to be the same as the fourth angle.It can also be provided that the respective reference angles and / or reference positions of the valve disc and the further valve disc can be different.

[0016] The number of rotational positions of the valve disc and / or the additional valve disc is not limited to two. In some embodiments, the sum of the number of rotational positions of the valve disc and the additional valve disc can correspond to at least the number of adjustable or selectable fluidic connections and / or flow paths.

[0017] In the first rotational position, a first opening may be fluidly connected to a second opening, and in the second rotational position, the first opening and / or the second opening may be fluidly connected to a third opening.

[0018] In the first rotational position, a first opening may be fluidly connected to the second opening, and in the second rotational position, a third opening may be fluidly connected to a fourth opening.

[0019] It can be provided that if at least two, several or all openings of the first group are fluidically connected, at least two, several or all openings of the second group cannot be fluidically connected.

[0020] However, other and / or additional fluidic connections may also be present and / or enabled depending on the respective rotational position of the valve disc and / or the additional valve disc(s). In some embodiments, additional valve discs, e.g., a third valve disc, may enable even greater variability and / or adjustability.

[0021] The valve disc and / or the additional valve disc can be detachable from the valve unit. This allows for easy replacement of the valve discs. The valve unit can also be easy to maintain and / or clean. Furthermore, the flow paths and / or fluidic connections can be changed and / or adapted by replacing one or more valve discs.

[0022] A rotational axis of the valve disc and a rotational axis of the additional valve disc can be aligned parallel. Alternatively or additionally, it can be provided that a rotational axis of the valve disc and a rotational axis of the additional valve disc can coincide. In some embodiments, a rotational axis of the valve disc and a rotational axis of at least one, several, or all additional valve discs can be aligned parallel and / or coincide. This can result in a particularly simple flow guidance.

[0023] The additional valve disc can be spaced apart from the valve disc in the direction of the rotational axis. In some embodiments, the additional valve disc can be arranged above the valve disc. If the valve unit has more than two valve discs, these can be arranged spaced apart from one another, one above the other, and / or stacked. This can result in a compact design of the valve unit. The valve unit can be comparatively small.

[0024] The additional valve disc can be rotatable independently of the valve disc. It can be provided that the valve disc and all additional valve discs can be rotated independently of each other and / or can be or be moved independently of each other.

[0025] It can be provided that the valve disc and the further valve disc, and / or respectively adjacent valve discs, can be sealed so that no leakage flow or the like can escape between the respective valve discs and / or is at least minimized. A leakage flow can be an undesired fluid escape. The valve disc and / or the further valve disc can be configured as an expansion valve. In some embodiments, a function as an expansion valve can result depending on the rotation of the valve disc and / or the further valve disc. For example, an expansion valve can be formed or become formed by selecting an overlap or a flow cross-section, and / or a corresponding function can be provided.

[0026] A flow cross-section can be varied at a flow opening of the valve disc line system depending on the rotation of the valve disc and / or the further valve disc.

[0027] A flow cross-section at a flow opening of the further valve disc line system can be variable depending on the rotation of the further valve disc and / or the rotation of the valve disc.

[0028] It can be provided that an overlap of a flow opening of the valve disc line system with one or more flow openings of the further valve disc line system can be adjustable depending on the rotation of the valve disc and / or the further valve disc. For example, this makes it possible to adjust the amount of fluid, e.g., a mass flow and / or a volume flow, that can flow from the valve disc into the further valve disc (or vice versa).

[0029] If the valve unit has at least two further valve discs, an overlap of a flow opening of the further valve disc line system of one of the further valve discs with one or more flow openings of the further valve disc line system of another of the further valve discs can be adjustable depending on the rotation of one further valve disc and / or the other further valve disc.

[0030] An overlap of a flow opening of the valve disc line system with at least one opening of the valve unit can be adjustable depending on the rotation of the valve disc. It can be provided that an overlap of a flow opening of the further valve disc line system with at least one opening of the valve unit can be adjustable depending on the rotation of the further valve disc. This makes it possible to adjust, for example, a quantity of fluid, for example a mass flow and / or a volume flow, that can flow from the valve disc and / or the further valve disc into the opening.

[0031] The valve disc and / or the additional valve disc can be adjustable in an axial direction. Alternatively or additionally, the valve disc and / or the additional valve disc can be adjustable in a direction parallel to the rotational axis of the valve disc and / or the additional valve disc. This allows a flow cross-section and / or an overlap between a flow opening of the valve disc and an opening, and / or between a flow opening of the additional valve disc and an opening, to be adjusted.

[0032] It can be provided that in the case of an axial adjustment, the valve disc and the further valve disc are or will be adjusted equally and / or by the same adjustment distance.

[0033] The valve unit may have a housing. The valve disc and the additional valve disc may be accommodated in the housing. It may be provided that all valve discs, in particular also all additional valve discs, may be accommodated in the housing. This may result in a compact design of the valve unit.

[0038] The valve unit may have a top surface. At least one opening may be arranged on a top surface of the valve unit. Alternatively or additionally, at least one opening may be arranged above the valve disc and / or the further valve disc.

[0039] The valve unit can be configured such that a volume flow and / or mass flow of a fluid flowing in or out through at least one opening can be adjusted depending on the rotation of the valve disc and / or the rotation of the further valve disc.

The axis of symmetry can be aligned parallel to and / or coincide with the rotational axis of the valve disc and / or the rotational axis of the other valve disc. The valve unit can have a peripheral surface. At least one opening can be arranged on a peripheral surface of the valve unit.

[0041] At least one opening can be arranged opposite another opening. In some embodiments, an opening can be arranged at an angle perpendicular to a longitudinal direction and / or extension direction of the valve unit, and / or perpendicular to the rotation axis. It can be provided that at least two openings can be arranged at the same height in the longitudinal direction and / or extension direction of the valve unit, and / or along the rotation axis.

[0042] The valve disc line system can have one or more flow lines, which in some embodiments can be fluidically separated from one another. The further valve disc line system can have one or more flow lines, which in some embodiments can be fluidically separated from one another. It can be provided that at least two, several or all flow lines of the valve disc line system and / or the further valve disc line system can be fluidically separated. If two flow lines are fluidically separated, it can be provided that they do not have any common flow openings. If two flow lines are fluidically separated, it can be provided that in the valve disc and / or the further valve disc, no fluid can flow and / or be exchanged between the two flow lines.

[0043] At least one flow line can be curved. It can be provided that at least one flow line can run at an angle of approximately 90°. Alternatively or additionally, at least one flow line can be configured to deflect a fluid flowing through the flow line by an angle of approximately 90°.

[0044] At least one flow line may have a flow opening spaced from the axis of rotation in a radial direction.

[0045] At least one flow line can run from one flat side of the valve disc to another flat side of the valve disc opposite the flat side. At least one flow line can run from one flat side of the further valve disc to another flat side of the further valve disc opposite the flat side.

[0046] At least one flow line can run perpendicular to the rotational axis and / or parallel to a flat side of the valve disc. At least one flow line can run perpendicular to the rotational axis and / or parallel to a flat side of the valve disc. At least one flow line can run perpendicular to the rotational axis and / or parallel to a flat side of the additional valve disc.

[0047] The flow lines can be arranged and / or selected in such a way that they can enable certain fluidic connections of the openings at certain rotational positions.

[0048] The valve disc line system can be configured to form a heat exchanger. A first flow line and a second flow line can be arranged and / or extend in the valve disc in such a way that they form a heat exchanger. The further valve disc line system can be configured to form a heat exchanger.

A first flow line and a second flow line may be fluidically connected to the mixing chamber, so that fluid transported by the first flow line and fluid transported by the second flow line can be mixed in the mixing chamber.

[0051] The valve unit may include a feed pump. The feed pump may be configured to feed fluid from at least one opening to at least one other opening if they are fluidically connected. This may result in good flow through the valve unit. If the valve unit includes a feed pump, in some embodiments, additional pump units in the fluid distribution system may be omitted or reduced, and / or at least the number of pump units in the fluid distribution system may be reduced.

[0052] The feed pump can be located below the valve disc. The feed pump can be located in a chamber of the valve unit. The feed pump and / or the chamber can be located in the housing of the valve unit. This allows for a compact design of the valve unit.

[0084] The further valve disc 30 can be spaced from the valve disc 20 in the direction of the axis of rotation D. In some embodiments, the further valve disc 30 can be arranged above the valve disc 20. Alternatively or additionally, it can also be provided that the valve disc 20 can be arranged above at least one further valve disc 30. If the valve unit has more than one further valve disc 30, it can be provided that at least one further valve disc 30 can be arranged above at least one further valve disc 30, for example in the direction of the axis of rotation D.
