Description

Technical Field

[0001] This application relates to the field of fluid control technology, and in particular to a valve device and a thermal management system. Background Technology

[0002] With increasing global emphasis on environmental protection and sustainable development, new energy vehicles are rapidly developing and becoming an important direction for the automotive industry. Thermal management systems, especially those for new energy vehicles, often feature complex circuits to accommodate different heat pump modes. Multi-port valves are used to switch between different connection relationships according to system requirements. In addition to multi-port valves with mode-switching functions, proportional valves are also used to achieve proportional distribution of coolant. Therefore, if the system needs to simultaneously have mode-switching and proportional regulation functions, different valves are required in the system architecture to meet the usage requirements, resulting in a large number of valves and a complex thermal management system structure. Utility Model Content

[0003] This application provides a valve device and a thermal management system that can simultaneously switch between connection modes and proportional modes through the valve device, thereby reducing the number of valves required and simplifying the structure of the thermal management system.

[0004] In a first aspect, embodiments of this application provide a valve device, comprising: a housing, the housing including a first housing wall and a second housing wall, the first housing wall having a first hole, the second housing wall having a second hole and a plurality of third holes, the plurality of third holes being circumferentially spaced around the second hole; a valve core, the valve core being disposed within the housing and fitted against the second housing wall, the valve core having a flow channel groove on the side near the second housing wall, one end of the flow channel groove extending to communicate with the second hole, the valve core having a rotating shaft and a fourth hole, the rotating shaft and the second hole being coaxially arranged, the fourth hole being located on one side of the rotating shaft; and a driving member, the driving member driving the rotating shaft to rotate the valve core within the housing, and enabling the flow channel groove and the fourth hole to communicate with at least one of the plurality of third holes.

[0005] In the above technical solution, the valve device with the above structure drives the valve core to rotate within the housing via a driving component. The valve core cooperates with the second housing wall to achieve multiple communication modes and multiple proportional adjustments. Thus, the valve device integrates the functions of a multi-way valve and a proportional valve. While satisfying multiple communication modes and proportional adjustment modes, the valve device has a smaller size, saving space and reducing weight. Integrating multiple functions also reduces the number of valves and lowers costs. Moreover, switching between communication modes and proportional adjustments can be achieved through a single driving component. The valve device has a relatively simple structure, fewer parts, and is easy to control, thus improving its operational reliability.

[0006] In some embodiments, in the circumferential direction of the distribution of the plurality of third holes, the distance between any two adjacent edges of any two adjacent third holes is less than the size of the fourth hole and less than the size of the flow channel groove.

[0007] In the above technical solution, it is easy to achieve communication between the fourth hole and the two adjacent third holes, communication between the flow channel and the two adjacent third holes, and the proportional adjustment process. This solution is relatively simple, reducing manufacturing difficulty and cost. Moreover, the above solution can satisfy the above functions while making the overall structure of the valve device more compact, reducing the volume of the valve device, further reducing material usage, and thus reducing weight and cost.

[0008] In some embodiments, a portion of the plurality of third holes are first type holes and another portion are second type holes. In the circumferential direction in which the plurality of third holes are distributed, the size of the first type holes is larger than the size of the second type holes, and the second type holes are located between two adjacent first type holes.

[0009] In the above technical solution, the size difference between the first type of orifice and the second type of orifice allows the valve device to adapt to various flow path requirements. The first type of orifice is suitable for high-flow-rate connected flow paths, while the second type of orifice is suitable for low-flow-rate connected flow paths, thus meeting the flow distribution requirements under different operating conditions.

[0010] In some embodiments, the first type of hole is an arc-shaped hole, and the second type of hole is a round hole.

[0011] In the above technical solution, the first type of orifice is designed as an arc-shaped orifice, and the second type of orifice is designed as a circular orifice. The arc-shaped orifice is suitable for high-flow-rate connecting channels, and its shape better conforms to the natural path of fluid flow, which can reduce fluid resistance and pressure loss. The circular orifice is suitable for low-flow-rate connecting channels, which can meet low-flow-rate requirements. The combination of the two makes it easy to achieve connecting channels with different flow rates. In addition, the shapes of arc-shaped and circular orifices are relatively simple, the processes are relatively simple, and they are easy to manufacture, which can reduce manufacturing costs.

[0012] In some embodiments, in the circumferential direction of the distribution of a plurality of third holes, the distance between the adjacent edges of two first holes located on both sides of the second type of hole is greater than the size of the fourth hole.

[0013] In the above technical solution, since the distance between the adjacent edges of the two first-type holes is greater than the size of the fourth hole, and the second-type hole is the smallest hole among the multiple third holes, when the fourth hole is connected to the second-type hole, it will not be interfered with by the first-type holes on both sides. This is beneficial to realize that the first hole, the fourth hole and the third hole form only one connected flow path, thereby meeting the requirement of switching to a connected flow path with a smaller flow rate.

[0014] In some embodiments, the size of the fourth hole is L1 in the circumferential direction of the distribution of the plurality of third holes, and the size of the fourth hole is H1 in the rotational radial direction of the valve core, wherein H1 is less than L1.

[0015] In the above technical solution, the fourth hole, with its aforementioned structure, forms an elongated hole. While satisfying various connection modes and proportional adjustment functions, the fourth hole can be arranged adjacent to the second hole, thereby making the internal structure of the valve device more compact, reducing its size and weight. Furthermore, the fourth hole in this structure also forms a large overlap area with the third hole, allowing for a wider proportional adjustment range, improving the range and accuracy of flow control, and ultimately enhancing the flow regulation effect.

[0016] In some embodiments, the flow channel includes a first part and a second part that are interconnected. The first part extends along the rotational radial direction of the valve core and communicates with a second hole. The second part is located at the end of the first part away from the second hole. In the circumferential direction where a plurality of third holes are distributed, the size of the second part is larger than the size of the first part.

[0017] In the above technical solution, the first part extends along the radial direction of the valve core's rotation and communicates with the second hole, allowing fluid to flow from the second hole to the location of the third hole. The larger size of the second part allows the valve core to communicate with more third holes when rotating, and also creates a larger overlapping area with the third holes, increasing the proportional adjustment range to meet the requirements of more types of connected flow paths.

[0018] In some embodiments, both the valve core and the housing are circular.

[0019] In the above technical solution, the valve core and the housing are [missing information]. Furthermore, the circular structure allows for uniform distribution of fluid pressure across the valve core and housing, which helps reduce localized stress concentration and improves the service life of the valve device.

[0020] In some embodiments, the second shell wall is disposed adjacent to the first shell wall, the shell includes a third shell wall, the third shell wall is opposite to the second shell wall and adjacent to the first shell wall, the drive member is disposed on the third shell wall, and the rotating shaft passes through the third shell wall and is connected to the drive member.

[0021] In the above technical solution, the first hole, the second hole, and the third hole are all used to connect to external pipes. Therefore, the first and second shell walls facilitate the arrangement of surrounding pipes, which helps to reduce pipe length and lower costs. The third shell wall, which is opposite to the second shell wall, provides more space for the installation of the drive component, reduces interference during drive component installation, lowers the difficulty of installing or disassembling the drive component, and facilitates later maintenance or replacement.

[0022] In some embodiments, the valve device includes a first seal disposed between the valve core and the second housing wall, and the first seal has a first clearance hole corresponding to the second hole and the third hole.

[0023] In the above technical solution, the first sealing element ensures a sealed state between the valve core and the second shell wall, allowing the fluid medium inside the shell to flow only through the second, third, and fourth holes and the flow channel groove. This reduces the risk of leakage between different flow channels and also minimizes the risk of crossflow, improving the operational reliability of the valve device. The first clearance hole serves to prevent the first sealing element from interfering with the operation of the second and third holes.

[0024] Secondly, embodiments of this application also provide a thermal management system, including: a collector, the collector having an end face, the collector having a plurality of heat exchange channels inside, one end of the plurality of heat exchange channels extending to the end face, and a plurality of channel openings formed on the end face; a valve device of any of the preceding items, a second shell wall sealingly fitted to the end face, a second hole corresponding to and communicating with one of the plurality of channel openings, and a plurality of third holes corresponding to and communicating with the remaining channel openings one by one.

[0025] In the above technical solution, because the valve device can realize multiple connection modes and switch between different connection modes, while also performing proportional adjustment, it can integrate multiple valve functions and possess both connecting and proportional valve capabilities. Using this valve device in the thermal management system can reduce the number of components, simplify the piping connection structure, and thus reduce pipe length, thereby lowering costs. Furthermore, the valve device can achieve connection mode switching and proportional adjustment under the action of a single drive component, making control relatively simple and further reducing costs. Because the valve device integrates multiple functions and has a small overall size, it can also save space in the thermal management system.

[0062] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0063] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0066] In this application, "multiple" means two or more (including two).

[0067] With increasing global emphasis on environmental protection and sustainable development, new energy vehicles are rapidly developing and becoming an important direction for the automotive industry. Thermal management systems, especially those for new energy vehicles, often feature complex circuits to accommodate different heat pump modes. Multi-port valves are used to switch between different connection relationships according to system requirements. In addition to multi-port valves with mode-switching functions, proportional valves are also used to achieve proportional distribution of coolant. Therefore, if the system needs to simultaneously have mode-switching and proportional regulation functions, different valves are required in the system architecture to meet the usage requirements, resulting in a large number of valves and a complex thermal management system structure.

[0068] Based on the above considerations, in order to solve the problem that the thermal management system architecture requires different valves to meet the usage requirements, resulting in a large number of valves and a complex structure, the applicant has designed a valve device, including a housing, a valve core, and a drive component. The housing includes a first housing wall and a second housing wall. The first housing wall has a first hole, and the second housing wall has a second hole and multiple third holes, which are circumferentially spaced around the second hole. The valve core is located inside the housing and is sealed and fitted to the second housing wall. The valve core has a flow channel groove on the side near the second housing wall, one end of which extends to communicate with the second hole. The valve core has a rotating shaft and a fourth hole. The rotating shaft and the second hole are arranged coaxially, and the fourth hole is located on one side of the rotating shaft. The drive component drives the rotating shaft to rotate the valve core inside the housing and allows the flow channel groove and the fourth hole to communicate with at least one of the multiple third holes.

[0069] In this type of valve device, the valve core is driven to rotate within the housing by a drive component. The valve core, in conjunction with the second housing wall, enables multiple communication modes and proportional adjustments. This allows the valve device to integrate the functions of a multi-way valve and a proportional valve. While satisfying multiple communication and proportional adjustment modes, the valve device has a smaller size, saving space and reducing weight. Integrating multiple functions also reduces the number of valves, lowering costs. Furthermore, switching between communication modes and proportional adjustments can be achieved through a single drive component. The valve device has a simpler structure, fewer components, and is easier to control, thus improving its operational reliability.

[0070] The valve device disclosed in the embodiments of this application can be used, but is not limited to, in thermal management systems, water treatment and water supply systems, gas or oil pipeline systems, agricultural irrigation systems, etc.

[0071] This application provides a thermal management system using a valve device. The thermal management system may include, but is not limited to, air conditioning thermal management, battery thermal management, electric drive thermal management, and electronic control thermal management. The thermal management system can also be applied to vehicles, which may be, but are not limited to, gasoline-powered vehicles, natural gas-powered vehicles, or new energy vehicles, including pure electric vehicles, hybrid electric vehicles, and range-extended electric vehicles.

[0072] For ease of explanation, the following embodiments will be described using a valve device 100 according to an embodiment of this application as an example.

[0073] Reference Figures 1 to 5 , Figure 1 This is a schematic diagram of the structure of a valve device 100 provided in some embodiments of this application. The embodiments of this application provide a valve device 100, including: a housing 10, a valve core 20, and a drive member 30. The housing 10 includes a first housing wall 101 and a second housing wall 102. The first housing wall 101 has a first hole 101a, and the second housing wall 102 has a second hole 1021 and a plurality of third holes 1022. The plurality of third holes 1022 are circumferentially spaced around the second hole 1021. The valve core 20 is disposed inside the housing 10 and fitted against the second housing wall 102. The valve core 20 has a flow channel groove 201 on the side near the second housing wall 102. One end of the flow channel groove 201 extends to communicate with the second hole 1021. The valve core 20 has a rotating shaft 202 and a fourth hole 20a. The rotating shaft 202 and the second hole 1021 are axially arranged, and the fourth hole 20a is located on one side of the rotating shaft 202. The driving member 30 drives the rotating shaft 202 to rotate the valve core 20 inside the housing 10, and allows the flow channel groove 201 and the fourth hole 20a to communicate with at least one of the plurality of third holes 1022.

[0074] The housing 10 can refer to the main structural component of the valve device 100, serving a mechanical support and encapsulation function. The first housing wall 101 and the second housing wall 102 can refer to the shell walls forming the housing 10. The first housing wall 101 and the second housing wall 102 can be, but are not limited to, one of the top shell wall, bottom shell wall, and lateral shell walls of the housing 10. (Refer to...) Figure 2 The valve device 100 may have a first direction X, a second direction Y and a third direction Z. The first shell wall 101 may refer to the shell wall of the housing 10 arranged around the third direction Z. The second shell wall 102 may be the shell wall of the housing 10 located at one end of the third direction Z.

[0075] Valve core 20 can refer to the core control component of valve device 100, which directly controls the on / off state, flow rate, and flow direction of fluid through movement. Flow channel groove 201 can refer to a groove or channel structure formed on valve core 20, used to create a fluid passage. The shape of flow channel groove 201 can be, but is not limited to, straight, arc, spiral, or other complex shapes. Rotating shaft 202 can refer to a shaft-like component mounted on valve core 20, through which valve core 20 can rotate. (Refer to...) Figure 2 and Figure 3 The rotating shaft 202 can refer to a shaft extending along a third direction Z.

[0076] The driving component 30 can refer to the component that drives the rotating shaft 202 to rotate, and can be, but is not limited to, an electric motor, a pneumatic motor, a hydraulic motor, etc.

[0077] In the valve device 100 with the above structure, the first hole 101a is normally open to the cavity formed by the housing 10 and the valve core 20, and the second hole 1021 and the flow channel groove 201 are also normally open. Since the second housing wall 102 is provided with the second hole 1021 and a plurality of third holes 1022 arranged circumferentially around the second hole 1021, when the driving member 30 drives the rotating shaft 202 to rotate the valve core 20, when the valve core 20 rotates to a certain position, the flow channel groove 201 can be connected to one or more of the plurality of third holes 1022. Thus, the fluid medium can form a connecting path between the second hole 1021, the flow channel groove 201 and the third holes 1022. When the flow channel groove 201 is connected to one third hole 1022, a connecting flow path can be formed. When the flow channel groove 201 is connected to two or more third holes 1022, two or more connecting paths can be formed. The fourth hole 20a can also be connected to one or more of the third holes 1022, thereby forming one or more connected flow paths between the first hole 101a, the fourth hole 20a and the third hole 1022.

[0078] For example, refer to Figure 5 The flow channel 201 can flow with the second hole 1021 and the third hole 1022, thereby forming a connected flow path (see...). Figure 5 (As indicated by the arrow on the left), the fourth hole 20a can connect with the first hole 101a and the third hole 1022, thus forming a connected flow path (see...). Figure 5 The arrow on the right points to...

[0079] During the rotation of the valve core 20 by the driving component 30, the overlapping areas of the flow channel groove 201 and the third hole 1022, as well as the overlapping areas of the fourth hole 20a and the third hole 1022, can also be controlled, thereby enabling flow distribution and proportional adjustment. Since the overlapping areas of the flow channel groove 201 and the third hole 1022, as well as the overlapping areas of the fourth hole 20a and the third hole 1022, have a large range during the rotation of the valve core 20, multiple proportional ranges can be adjusted, thus achieving multi-level adjustment. It should be noted that by adjusting the number of third holes 1022, the valve device 100 can achieve a greater number of connection modes and proportional adjustment modes.

[0080] In the above technical solution, the valve device 100 with the above structure drives the valve core 20 to rotate within the housing 10 via the drive component 30. The valve core 20 cooperates with the second housing wall 102 to achieve multiple communication modes and multiple proportional adjustments. Thus, the valve device 100 can integrate the functions of a multi-way valve and a proportional valve. While satisfying multiple communication modes and proportional adjustment modes, the valve device 100 has a smaller size, saving space and reducing weight. By integrating multiple functions, the number of valves can also be reduced, lowering costs. Moreover, the switching of communication modes and proportional adjustment can both be achieved through a single drive component 30. The valve device 100 has a relatively simple structure, fewer parts, and is easy to control, which can improve the operational reliability of the valve device 100.

[0081] In some embodiments, refer to Figure 6 In the circumferential direction of the distribution of multiple third holes 1022, the distance between any two adjacent edges of any two adjacent third holes 1022 is less than the size of the fourth hole 20a and less than the size of the flow channel groove 201.

[0082] "The circumferential direction of the distribution of the third hole 1022" can refer to the circular distribution trajectory of multiple third holes 1022 around the valve core 20.

[0083] "The edge of the third hole 1022" can refer to the outer contour line of the third hole 1022. For ease of understanding, refer to... Figure 6 The distance between any two adjacent edges of the third hole 1022 can be L2, the size of the fourth hole 20a is L1, and the size of the flow channel groove 201 is L3. That is to say, L2 is less than L1 and L2 is less than L3.

[0084] In the above technical solution, it is easy to achieve communication between the fourth hole 20a and the two adjacent third holes 1022, communication between the flow channel 201 and the two adjacent third holes 1022, and the proportional adjustment process. This solution is relatively simple, reducing manufacturing difficulty and cost. Moreover, the above solution can satisfy the above functions while making the overall structure of the valve device 100 more compact, reducing the volume of the valve device 100, further reducing material usage, and thus reducing weight and cost.

[0085] In some embodiments, refer to Figure 2 , Figure 3 and Figure 6 A portion of the multiple third holes 1022 are first type holes 1022a, and another portion are second type holes 1022b. In the circumferential direction of the distribution of the multiple third holes 1022, the size of the first type holes 1022a is larger than the size of the second type holes 1022b, and the second type holes 1022b are located between two adjacent first type holes 1022a.

[0086] The first type of hole 1022a and the second type of hole 1022b can refer to two different shapes of holes, see reference. Figure 2 , Figure 3 and Figure 6 It is understood that, in the circumferential direction where the multiple third holes 1022 are distributed, the first type of hole 1022a is a hole with a larger length dimension, and the second type of hole 1022b is a hole with a smaller length dimension. The first type of hole 1022a and the second type of hole 1022b can be, but are not limited to, strip-shaped holes, waist-shaped holes, round holes, arc-shaped holes, etc., and the shapes of the first type of hole 1022a and the second type of hole 1022b can be the same or different, and no specific limitation is made in the above embodiments.

[0087] "The second type hole 1022b is located between two adjacent first type holes 1022a" can mean that all the second type holes 1022b and the first type holes 1022a are arranged alternately, or that some of the first type holes 1022a can be arranged adjacently, while the other part of the first type holes 1022a and the second type holes 1022b are arranged alternately.

[0088] In the above technical solution, the size difference between the first type of hole 1022a and the second type of hole 1022b enables the valve device 100 to adapt to various flow path requirements. The first type of hole 1022a is suitable for large flow path requirements, while the second type of hole 1022b is suitable for small flow path requirements, thus meeting the flow distribution requirements under different operating conditions.

[0089] In some embodiments, refer to Figure 2 , Figure 3 and Figure 6 The first type of hole 1022a is an arc-shaped hole, and the second type of hole 1022b is a round hole.

[0090] An arc-shaped hole can refer to a structure in which the edge or outline of the hole is arc-shaped or curved. It can be, but is not limited to, partially arc-shaped, spiral-shaped, elliptical, or other complex curved shapes.

[0091] A round hole can refer to a structure where the edge or outline of the hole is circular. It has a perfectly symmetrical shape, a uniform diameter, and smooth edges.

[0092] In the above technical solution, the first type of hole 1022a is designed as an arc-shaped hole, and the second type of hole 1022b is designed as a circular hole. The arc-shaped hole is suitable for high-flow-rate connecting channels, and its shape better conforms to the natural path of fluid flow, which can reduce fluid resistance and pressure loss. The circular hole is suitable for low-flow-rate connecting channels, which can meet low-flow-rate requirements. The combination of the two makes it easy to achieve the requirements of connecting channels with different flow rates. In addition, the shapes of arc-shaped holes and circular holes are relatively simple, the processes are relatively simple, and they are easy to manufacture, which can reduce manufacturing costs.

[0093] In some embodiments, refer to Figure 6 In the circumferential direction of the distribution of multiple third holes 1022, the distance between the adjacent edges of two first holes 1022a located on both sides of the second hole 1022b is greater than the size of the fourth hole 20a.

[0094] Reference Figure 6 "The distance between the adjacent edges of two first-class holes 1022a located on both sides of the second-class hole 1022b in the circumferential direction of the distribution of multiple third holes 1022" can be L4; "The size of the fourth hole 20a in the circumferential direction of the distribution of multiple third holes 1022" can be L1, that is, L4 is greater than L1.

[0095] In the above technical solution, since the distance between the adjacent edges of the two first-type holes 1022a is greater than the size of the fourth hole 20a, and the second-type hole 1022b is the smallest hole among the multiple third holes 1022, when the fourth hole 20a is connected to the second-type hole 1022b, it will not be interfered with by the first-type holes 1022a on both sides. This is conducive to realizing that the first hole 101a, the fourth hole 20a and the third hole 1022 form a connected flow path, which meets the requirement of switching to a connected flow path with a smaller flow rate.

[0096] In some embodiments, refer to Figure 6 In the circumferential direction where multiple third holes 1022 are distributed, the size of the fourth hole 20a is L1, and in the rotational radial direction of the valve core 20, the size of the fourth hole 20a is H1, wherein H1 is less than L1.

[0097] H1 being less than L1 can mean that the fourth hole 20a is a rectangular or nearly rectangular hole. For example, the fourth hole 20a can be an oblong hole, an arc-shaped hole, etc.

[0098] In the above technical solution, the fourth hole 20a, with the aforementioned structure, can form an elongated hole. While satisfying multiple connection modes and proportional adjustment functions, the fourth hole 20a can be arranged close to the second hole 1021. This allows for a more compact internal structure of the valve device 100, reducing its size and weight. Furthermore, the fourth hole 20a with the aforementioned structure can form a large overlap area with the third hole 1022, enabling a wider proportional adjustment range, improving the range and accuracy of flow control, and ultimately enhancing the flow regulation effect.

[0099] In some embodiments, refer to Figure 3 and Figure 5 The flow channel 201 includes a first part 2011 and a second part 2012 that are interconnected. The first part 2011 extends along the rotational radial direction of the valve core 20 and communicates with the second hole 1021. The second part 2012 is located at the end of the first part 2011 away from the second hole 1021. In the circumferential direction where a plurality of third holes 1022 are distributed, the size of the second part 2012 is larger than the size of the first part 2011.

[0100] The first part 2011 extends radially along the rotation of the valve core 20 and communicates directly with the second hole 1021, guiding fluid from the second hole 1021 into the flow channel 201. The second part 2012 is located at the end of the first part 2011 away from the second hole 1021, and is larger in size, used to optimize the flow path and distribution of fluid.

[0101] In the above technical solution, the first part 2011 extends along the radial direction of the valve core 20 and communicates with the second hole 1021, allowing fluid to flow from the second hole 1021 to the location of the third hole 1022. The larger size of the second part 2012 allows the valve core 20 to communicate with more third holes 1022 when rotating, and also allows for a larger overlapping area with the third holes 1022, which can increase the proportional adjustment range to meet the requirements of more types of connected flow paths.

[0102] In some embodiments, refer to Figures 2 to 4 Both the valve core 20 and the housing 10 are circular.

[0103] In the above technical solution, the valve core 20 and the housing 10 are circular, which allows the valve device 100 to be constructed as a disc valve. The valve device 100 is relatively low in height, saving space. Moreover, the circular valve core 20 and housing 10 are easier to process and manufacture, reducing manufacturing process difficulty, improving product yield, and thus reducing costs. At the same time, the circular structure also allows the fluid pressure to be evenly distributed on the valve core 20 and housing 10, which helps to reduce the problem of local stress concentration and improve the service life of the valve device 100.

[0104] In some embodiments, refer to Figures 2 to 5 The second shell wall 102 is disposed adjacent to the first shell wall 101. The shell 10 includes a third shell wall 103, which is opposite to the second shell wall 102 and adjacent to the first shell wall 101. The driving member 30 is disposed on the third shell wall 103, and the rotating shaft 202 passes through the third shell wall 103 and is connected to the driving member 30.

[0105] In other words, the first shell wall 101, the second shell wall 102, and the third shell wall 103 together constitute the shell 10. For example, the second shell wall 102 can be the bottom wall, the first shell wall 101 can be the side wall, and the third shell wall 103 can be the top wall. For another example, the second shell wall 102 can be the top wall, the first shell wall 101 can be the side wall, and the third shell wall 103 can be the bottom wall.

[0106] Optionally, refer to Figure 2 , Figure 3 and Figure 5 The third shell wall 103 may be provided with a mounting hole 103a, into which the rotating shaft 202 is installed and sealed. In the above technical solution, the first hole 101a, the second hole 1021, and the third hole 1022 are all used to connect to external pipes. Therefore, the first shell wall 101 and the second shell wall 102 facilitate the arrangement of surrounding pipes, which helps to reduce the length of pipes and reduce costs. The third shell wall 103 is opposite to the second shell wall 102, which can provide more space for the installation of the drive component 30, reduce interference during the installation of the drive component 30, reduce the difficulty of installing or disassembling the drive component 30, and facilitate later maintenance or replacement.

[0107] In some embodiments of this application, reference is made to Figures 1 to 3 , Figure 5 The shell 10 includes a shell body 11 and a shell cover 12. The shell body 11 is provided with a first shell wall 101 and a second shell wall 102, and the shell cover 12 covers the shell body 11.

[0108] Shell body 11 can refer to a shell structure having a bottom wall and a perimeter of side walls, and being open at one end. Shell cover 12 can refer to a structural component used to seal shell body 11.

[0109] In the above technical solution, by configuring the housing 10 into a structure including a housing body 11 and a housing cover 12, the housing cover 12 can be removed from the housing body 11, facilitating the installation or removal of the internal valve core 20, simplifying subsequent maintenance, and reducing operating costs. Furthermore, the housing 10 is a split structure, allowing the housing body 11 and housing cover 12 to be manufactured separately, further reducing manufacturing costs. The housing cover 12 also provides support and fixation for the installation of the valve core 20, improving the installation reliability of the valve core 20.

[0110] In some embodiments of this application, reference is made to Figure 2 , Figure 3 and Figure 5 The valve device 100 also includes a first sealing element 40, which is sealed between the valve core 20 and the second shell wall 102. The first sealing element 40 is provided with a first clearance hole 40a corresponding to the second hole 1021 and the third hole 1022.

[0111] The first sealing element 40 can refer to a component that performs a sealing function, such as a gasket, a sealing film, etc. For example, the first sealing element 40 can be a gasket.

[0112] There can be multiple first clearance holes 40a. One of the multiple first clearance holes 40a is set to correspond to the second hole 1021, and the rest are set to correspond one-to-one with the multiple third holes 1022. The shape of the first clearance hole 40a matches the corresponding second hole 1021, and the shape and size of the two are equal. Similarly, the shape of the first clearance hole 40a matches the corresponding third hole 1022.

[0113] In the above technical solution, the first sealing element 40 ensures a sealed state between the valve core 20 and the second shell wall 102, allowing the fluid medium inside the shell 10 to flow only through the second hole 1021, the third hole 1022, the fourth hole 20a, and the flow channel groove 201. This reduces the risk of leakage between different flow channels and also minimizes the risk of crossflow, improving the operational reliability of the valve device 100. The first clearance hole 40a serves a clearance function, ensuring that the first sealing element 40 does not affect the operation of the second hole 1021 and the third hole 1022.

[0114] In some embodiments of this application, reference is made to Figure 2 , Figure 3 and Figure 5 The valve device 100 also includes a second seal 50, which is sealed on the outside of the second housing wall 102.

[0115] The second sealing element 50 can refer to a component that performs a sealing function, such as a sealing gasket, a sealing film, etc. For example, the second sealing element 50 can be a sealing gasket. It should be noted that the second sealing element 50 is provided with a second clearance hole 50a corresponding to the second hole 1021 and the third hole 1022.

[0116] In the above technical solution, the second sealing element 50 can keep the second shell wall 102 sealed with the external connecting parts or connecting pipes, so that the fluid medium inside the shell 10 can only flow through the second hole 1021 and the third hole 1022, which can reduce the risk of fluid medium leakage and improve the working reliability of the valve device 100.

[0117] Reference Figure 7 This application also provides a thermal management system 1000, including: a current collector 200 and a valve device 100 of any of the above embodiments. The current collector 200 has an end face 2001, and a plurality of heat exchange channels 2002 are provided inside the current collector 200. One end of the plurality of heat exchange channels 2002 extends to the end face 2001, and a plurality of flow ports 200a are formed on the end face 2001. A second shell wall 102 is sealed and fitted to the end face 2001. A second hole 1021 corresponds to and communicates with one of the plurality of flow ports 200a. A plurality of third holes 1022 correspond to and communicate with the remaining flow ports 200a one by one.

[0118] The collector 200 can refer to a component that integrates multiple heat exchange channels 2002, thus integrating the functions of multiple pipes. The collector 200 can be, but is not limited to, rectangular, circular, etc. The end face 2001 can refer to a surface of the collector 200, which can be sealed with the second shell wall 102 of the valve device 100 through the second sealing element 50, thereby enabling the second hole 1021 and multiple third holes 1022 of the second shell wall 102 to correspondingly engage with the multiple heat exchange channels 2002.

[0119] For ease of understanding, the first hole 101a of the valve device 100 can be connected to the first pipe 300, through which a fluid medium can flow. The second hole 1021 is connected to the second pipe 400, and multiple third holes 1022 are all connected to the third pipe 500.

[0120] One or more of the third conduits 500 may, together with the manifold 200, the valve device 100, and the first conduit 300, form one or more connected flow paths. For example, refer to Figure 7In the valve device 100, when the valve core 20 rotates to the point where the fourth hole 20a is connected to only one third hole 1022, the first pipe 300, the valve device 100, the collector 200, and the third pipe 500 together form a connected flow path. By continuing to adjust the angle of the valve core 20, the size of the overlapping area between the fourth hole 20a and the current third hole 1022 can be adjusted, thereby achieving proportional adjustment. When the valve core 20 rotates to the point where the fourth hole 20a is connected to two third holes 1022, the first pipe 300, the valve device 100, the collector 200, and the third pipe 500 together form a connected flow path, and the first pipe 300, the valve device 100, the collector 200, and the other third pipe 500 together form another connected flow path. By adjusting the angle of the valve core 20, the size of the overlapping area between the fourth hole 20a and the two third holes 1022 can be adjusted, thereby achieving proportional adjustment of the two connected flow paths.

[0121] One or more of the multiple third pipes 500 can, together with the manifold 200, the valve device 100, and the second pipe 400, form another or more connected flow paths. For example, refer to Figure 7 In the valve device 100, when the valve core 20 rotates to the point where the flow channel groove 201 is connected to only one third hole 1022, the second pipe 400, the valve device 100, the collector 200, and the third pipe 500 together form a connected flow path. By continuing to adjust the angle of the valve core 20, the size of the overlapping area between the flow channel groove 201 and the current third hole 1022 can be adjusted, thereby achieving proportional adjustment. When the valve core 20 rotates to the point where the flow channel groove 201 is connected to two third holes 1022, the second pipe 400, the valve device 100, the collector 200, and the third pipe 500 together form a connected flow path, and the second pipe 400, the valve device 100, the collector 200, and the other third pipe 500 together form another connected flow path. By adjusting the angle of the valve core 20, the size of the overlapping area between the flow channel groove 201 and the two third holes 1022 can be adjusted, thereby achieving proportional adjustment of the two connected flow paths.

[0122] In the above technical solution, since the valve device 100 can realize multiple connection modes and switch between different connection modes, and can also perform proportional adjustment, the valve device 100 can integrate multiple valve functions and has the functions of a connecting valve and a proportional valve. Using this valve device 100 in the thermal management system 1000 can reduce the number of parts, simplify the pipeline connection structure, and thus reduce the pipeline length, thereby reducing costs. Moreover, the valve device 100 can realize connection mode switching and proportional adjustment under the action of a single driving component 30, making control relatively simple and also reducing costs. Because the valve device 100 can integrate multiple functions and has a relatively small overall size, it can also save space in the thermal management system 1000.

The driving component 30 can drive the valve core 20 to rotate within the housing 10 and connect the flow channel groove 201 and the fourth hole 20a to at least one of the plurality of third holes 1022.
