Description

Technical Field

[0001] The present disclosure relates to the field of fluid control, and in particular, to a flow channel plate and a fluid device having the same. Background Art

[0002] Thermal management systems are widely used in various devices and systems. For example, they can be applied to vehicles, particularly new energy vehicles, to ensure that the vehicle's target objects are maintained in a suitable temperature environment. A thermal management system may include a multi-way valve and a matching manifold plate. A multi-way valve switches its connection mode by rotating the valve core, thereby changing the connectivity of multiple pipes connected to the manifold plate. However, to meet complex and diverse connectivity requirements, traditional multi-way valves require relatively complex structures and large sizes. Utility Model Content

[0003] In view of this, the present disclosure provides a flow channel plate and a fluid device having the same, aiming to solve the problem that conventional multi-way valves have a relatively complex structure and a large volume in order to cope with complex and diverse connection requirements.

[0004] On the one hand, the present disclosure provides a flow channel plate. The flow channel plate provided by the present disclosure is suitable for matching with a multi-way valve. The multi-way valve includes a valve core that can be driven to rotate, and the valve core includes multiple valve ports. The flow channel plate includes multiple valve interfaces and multiple pipe interfaces. The multiple valve interfaces include a first valve interface and a second valve interface separated by at least one valve interface. The first valve interface is connected to a valve port when the valve core rotates to one position. The second valve interface is connected to another valve port when the valve core rotates to another position. The multiple pipe interfaces are suitable for being connected to multiple external pipe channels respectively. Each pipe interface corresponds to at least one valve interface connected thereto. One of the multiple pipe interfaces is connected to both the first valve interface and the second valve interface.

[0005] According to the flow channel plate provided by the present disclosure, the same pipe interface of the flow channel plate is connected to two non-adjacent valve interfaces of the flow channel plate. These two valve interfaces are respectively connected to two valve ports of the multi-way valve when the valve core rotates to different positions. Therefore, the same pipe interface can be connected to two valve ports when the valve core rotates to different positions. In this way, the flow channel plate and the multi-way valve can cooperate to provide a variety of operating modes to meet more complex or diverse connection requirements. Due to the presence of the flow channel plate in which the same pipe interface is connected to the two first valve interfaces, the structure of the multi-way valve connected thereto is simplified and the volume is reduced.

[0006] In some embodiments, the plurality of pipe interfaces include a first pipe interface, which is connected to both the first valve interface and the second valve interface. The flow channel plate is provided with at least one bypass channel and at least one main channel, wherein the at least one bypass channel includes a first bypass channel. The at least one main channel includes a first main channel. The first pipe interface is connected to the first valve interface or the second valve interface via the first main channel. The first valve interface and the second valve interface are connected via the first bypass channel.

[0007] According to this structure, the first pipe interface is connected to one of the first valve interface and the second valve interface through the first main channel, and the first valve interface is connected to the second valve interface through the first bypass channel, thereby connecting the first pipe interface to both the first valve interface and the second valve interface.

[0008] In some embodiments, the plurality of valve interfaces are arranged in a ring shape or a partially ring shape along a circumferential direction to form a middle region between the plurality of valve interfaces. The first bypass flow channel at least partially extends through the middle region.

[0009] On the one hand, this structure fully utilizes the space surrounded by the multiple valve interfaces, so that the addition of the first bypass channel does not significantly increase the volume of the channel plate, making it a more compact structure. On the other hand, according to this structure, the distance of the first bypass channel is shorter, thereby reducing the flow resistance.

[0010] In some embodiments, the plurality of valve interfaces further include a third valve interface and a fourth valve interface separated by at least one valve interface. The third valve interface is connected to one valve port when the valve core rotates to one position, and the fourth valve interface is connected to another valve port when the valve core rotates to another position. The plurality of pipe interfaces further include a second pipe interface, and the second pipe interface is connected to both the third valve interface and the fourth valve interface. At least one bypass channel includes a second bypass channel, and at least one main channel includes a second main channel. The second pipe interface is connected to the third valve interface or the fourth valve interface through the second main channel, and the third valve interface and the fourth valve interface are connected through the second bypass channel. The shortest distance between the third valve interface and the fourth valve interface is smaller than the shortest distance between the first valve interface and the second valve interface.

[0011] The first pipe interface is connected to the non-adjacent first and second valve interfaces, and the second pipe interface is connected to the non-adjacent third and fourth valve interfaces. In addition, the shortest distance between the third and fourth valve interfaces is smaller than the shortest distance between the first and second valve interfaces. This structure enables the flow channel plate and the multi-way valve to cooperate to provide more diverse and complex connection states, thereby meeting more diverse and complex connection requirements.

[0012] In some embodiments, the first valve interface, the fourth valve interface, the third valve interface and the second valve interface are arranged in sequence along the circumferential direction.

[0013] According to the arrangement of the first to fourth valve interfaces, the first bypass flow path and the second bypass flow path do not need to intersect, which helps to reduce the structural complexity of the flow channel plate and simplify the structure of the flow channel plate.

[0014] In some embodiments, the multiple valve interfaces include a fifth valve interface, the fifth valve interface is located between the third valve interface and the fourth valve interface, and the orthographic projection of the second bypass channel on the plane where the multiple valve interfaces are located at least partially overlaps with the fifth valve interface.

[0015] According to this structure, the second bypass channel will occupy the back space of the fifth valve interface, ensuring a larger width and smaller flow resistance.

[0016] In some embodiments, the channel wall of the first bypass channel includes an extension portion located in the middle area, and the extension portion is in a smooth arc shape.

[0017] When the fluid medium in the first bypass flow path flows through the middle area, it is guided by the extended portion of the flow channel wall. The balanced arc-shaped extended portion helps reduce flow resistance and suppress turbulence.

[0018] In some embodiments, the flow channel plate is further provided with a communication port, which spans the flow channel wall between the first main flow channel and another main flow channel adjacent thereto, and the first pipe interface is connected with both the first main flow channel and the other main flow channel through the communication port.

[0019] The first pipe interface connects to both the first and second main channels via a connecting port that spans the first main channel and the second main channel. This allows the first pipe interface to connect not only to the first and second valve interfaces via the first main channel and the first bypass channel, but also to the other valve interface via the second main channel. This allows one pipe interface to connect to at least three valve interfaces, enabling the manifold plate and multi-way valve to collaborate to provide more operating modes and meet more complex or diverse connectivity requirements.

[0020] In some embodiments, the flow channel plate includes a first plate body and a second plate body, a plurality of valve interfaces are provided on the side of the first plate body facing away from the second plate body, a protruding first wall portion is provided on the side of the first plate body facing the second plate body, and a protruding second wall portion is provided on the side of the second plate body facing the first plate body, and the first wall portion and the second wall portion are combined to form at least one main flow channel and at least one bypass flow channel.

[0021] According to this structure, the two plates are first formed separately by injection molding or the like, and then assembled (hot plate welding) together to form a flow channel plate having multiple flow channels therein. Therefore, the flow channel plate having this structure is easy to manufacture.

[0022] On the other hand, the present disclosure further provides a fluid device, which includes the flow channel plate according to the above aspect and a multi-way valve connected to the flow channel plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Numerous specific details are set forth below to provide an understanding of the structure, function, and use of the embodiments described in the specification and illustrated in the accompanying drawings. It is understood that the embodiments described and illustrated herein are non-limiting examples, and thus it is recognized that the specific structural and functional details disclosed herein are representative and exemplary. Modifications and changes may be made to these embodiments without departing from the scope of the claims.

[0036] <Exemplary Fluid Device>

[0037] The present disclosure provides a fluid device 100. The fluid device 100 can be applied to a thermal management system, which can be applied to a vehicle, especially a new energy vehicle. Figure 1 The fluidic device 100 may include a multi-way valve 10 and a manifold plate 20. The multi-way valve 10 may be coupled to the manifold plate 20, such that multiple external pipelines connected to the manifold plate 20 are connected to the multi-way valve 10 through flow channels within the manifold plate 20. In one example, the multi-way valve 10 may be mounted on the manifold plate 20. In other examples, the multi-way valve 10 may be coupled to the manifold plate via an intermediate component.

[0038] The multi-way valve 10 and the flow channel plate 20 are described below with examples.

[0039] <Exemplary Multi-Port Valve>

[0040] refer to Figure 3 and Figure 4 The multi-way valve 10 may include a valve body 11 and a valve core 12. The valve core 12 may be disposed in the valve body 11 and may be driven to rotate relative to the valve body 11 about the axis AA. By way of example only, the valve body 11 may include a first housing portion 111 and a second housing portion 112. The two housing portions 111 and 112 may be assembled together to form the valve body 11. It will be appreciated that in other examples, the valve body 11 may be integrally formed or may be composed of three or more assembled housing portions.

[0041] The valve body 11 may be provided with a plurality of valve openings 13, which may be arranged along a direction around axis AA. The valve core 12 may be provided with a plurality of valve ports 14, which may also be arranged along a direction around axis AA. As the valve core 12 is driven and rotated relative to the valve body 11, the plurality of valve ports 14 and the plurality of valve openings 13 may form different fluid paths, thereby switching the communication mode of the multi-way valve 10 and the connection status of the multiple external flow paths to accommodate different operating modes of the thermal management system.

[0042] For example, when the valve core 12 is in one position, one of the valve ports is defined as the first valve port, and the first valve port can be connected to one of the valve body openings opposite to each other, and the valve body opening is defined as the first valve body opening, thereby forming a fluid path; when the valve core 12 is rotated to another position, the first valve port can be connected to another valve body opening opposite to each other to form another fluid path, and the valve body opening is defined as the second valve body opening, thereby realizing the switching connection mode of the multi-way valve 10.

[0043] <Exemplary Flow Channel Plate>

[0044] refer to Figure 5 and Figure 6, the flow channel plate 20 can be provided with multiple valve interfaces 23 and multiple pipe interfaces 24. When the flow channel plate 20 is matched with the multi-way valve 10, the multiple valve interfaces 23 of the flow channel plate 20 can be respectively connected to the multiple valve body openings 13 of the multi-way valve 10. As an example, the multiple valve interfaces 23 can be arranged in a ring shape or a partial ring shape around the axis AA, and the end face of the flow channel plate 20 provided with multiple valve interfaces 23 carries the multi-way valve 10, so that the multiple valve interfaces 23 are respectively opposite to the multiple valve body openings 13 to achieve communication. The multiple pipe interfaces 24 can be respectively connected to multiple external pipelines, so that the fluid medium can flow from the external pipeline into the flow channel plate 20, and can also flow from the flow channel plate 20 into the external pipeline. For example, the multiple external pipelines can be part of a thermal management system for transporting and transferring fluid media for heating or cooling. Each pipe interface 24 is connected to at least one corresponding valve interface 23.

[0045] Combine Figure 7 and Figure 8 , the multiple valve interfaces 23 may include a first valve interface 23a and a second valve interface 23b. The first valve interface 23a and the second valve interface 23b may be separated by at least one valve interface 23. That is, the first valve interface 23a and the second valve interface 23b may be non-adjacent with at least one valve interface 23 between them. The multiple pipe interfaces 24 may include a first pipe interface 24a. The first valve interface 23a and the second valve interface 23b are both connected to the first pipe interface 24a. During operation, when the valve core 12 of the multi-way valve 10 rotates to one position, the first valve interface 23a may be connected to one valve port 14 of the valve core 12 through the corresponding valve body opening 13; when the valve core 12 rotates to another position, the second valve interface 23b may be connected to the other valve port 14 through the corresponding valve body opening 13.

[0046] According to the flow channel plate 20 provided by the present disclosure, the same pipe interface 24a of the flow channel plate 20 is connected to two non-adjacent valve interfaces 23a and 23b. These two valve interfaces 23a and 23b are respectively connected to the two valve ports 14 of the multi-way valve 10 when the valve core 12 rotates to different positions. Therefore, the same pipe interface 24a can be connected to the two valve ports 14 when the valve core 12 rotates to different positions. In this way, the flow channel plate 20 and the multi-way valve 10 can cooperate to provide more connection modes to meet more complex or diverse connection requirements. Due to the existence of the flow channel plate 20 in which the same pipe interface 24a is connected to the two first valve interfaces 23a and 23b, the structure of the multi-way valve 10 connected thereto is simplified and the volume is reduced.

[0047] Continue to refer Figure 7 and Figure 8The flow channel plate 20 may be provided with at least one main flow channel 25 and at least one bypass flow channel 26. The at least one main flow channel 25 may include a first main flow channel 25a. The at least one bypass flow channel 26 may include a first bypass flow channel 26a. The first pipe interface 24a may be connected to the first valve interface 23a via the first main flow channel 25a, while the first valve interface 23a and the second valve interface 23b may be connected via the first bypass flow channel 26a. Accordingly, the first pipe interface 23a is connected to the first valve interface 23a via the first main flow channel 25a, while the first valve interface 23a and the second valve interface 23b are connected via the first bypass flow channel 26a, thereby achieving communication between the first pipe interface 24a and both the first valve interface 23a and the second valve interface 23b.

[0048] In other examples, the first pipe interface 24a may be connected to the second valve interface 23b via the first main channel 25a. Furthermore, in other examples of the present disclosure, two branch channels may be formed downstream of the first pipe interface 24a, each extending to two main channels 25. These two main channels 25 are connected to the first valve interface 23a and the second valve interface 23b, respectively. In this way, the first pipe interface 24a may be connected to both the first valve interface 23a and the second valve interface 23b. There are many ways to connect the same pipe interface 24 to two non-adjacent pipe interfaces 24, and this disclosure does not impose any particular restrictions on this.

[0049] Continue to refer Figure 7 and Figure 8 , multiple valve interfaces 23 can be arranged in a circular or partially circular shape along a circumferential direction, that is, in a direction around the axis AA, to form an intermediate area between the multiple valve interfaces 23. For ease of understanding, the intermediate area is indicated by a dotted line in the figure. The first bypass channel 26a can at least partially extend through the intermediate area. On the one hand, this structure makes full use of the space surrounded by the multiple valve interfaces 23, so that the addition of the first bypass channel 26a does not significantly increase the volume of the flow channel plate 20, making it have a more compact structure. On the other hand, according to this structure, the distance of the first bypass channel 26a is shorter, and thus the flow resistance is smaller.

[0050] Continue to refer Figure 7 and Figure 8The multiple valve interfaces 23 may further include a third valve interface 23c and a fourth valve interface 23d. The third valve interface 23c and the fourth valve interface 23d may be separated by at least one valve interface 23. That is, the third valve interface 23c and the fourth valve interface 23d may be non-adjacent, separated by at least one valve interface 23. During operation, when the valve core 12 of the multi-way valve 10 rotates to one position, the third valve interface 23c communicates with one valve port 14 of the valve core 12; when the valve core 12 rotates to another position, the fourth valve interface 23d communicates with another valve port 14 of the valve core 12. The multiple pipe interfaces 24 may further include a second pipe interface 24b, which may communicate with both the third valve interface 24c and the fourth valve interface 24d. The shortest distance between the third valve interface 23c and the fourth valve interface 24d is less than the shortest distance between the first valve interface 23a and the second valve interface 23b. According to this structure, the first pipe interface 24a is connected to the non-adjacent first and second valve interfaces 23a and 23b, and the second pipe interface 24b is connected to the non-adjacent third and fourth valve interfaces 23c and 23d, and the shortest distance between the third and fourth valve interfaces 23c and 23d is smaller than the shortest distance between the first and second valve interfaces 23a and 23b. This structure enables the flow channel plate 20 and the multi-way valve 10 to cooperate to provide more diverse and complex connection states, thereby meeting more diverse and complex connection requirements.

[0051] Continue to refer Figure 7 and Figure 8 The at least one main flow channel 25 may further include a second main flow channel 25b, and the at least one bypass flow channel 26 may further include a second bypass flow channel 26b. The second pipe interface 24b may be connected to the third valve interface 23c through the second main flow channel 25b, and the third valve interface 23c and the fourth valve interface 23d may be connected through the second bypass flow channel 26b.

[0052] In other examples, the second pipe port 24b may be connected to the fourth valve port 23d via the second main flow channel 25b. Furthermore, in other examples, two branch flow channels may be formed downstream of the third pipe port 24c, each extending to two main flow channels 25. These two main flow channels 25 are connected to the third and fourth valve ports 23c and 23d, respectively. In this way, the second pipe port 24b can also be connected to both the third and fourth valve ports 23c and 23d.

[0053] Continue to refer Figure 7 and Figure 8The first valve interface 23a, the fourth valve interface 23d, the third valve interface 23c, and the second valve interface 23b can be arranged sequentially along a direction around the axis AA. With this arrangement of the first to fourth valve interfaces 23a-23d, the first bypass flow path 26a and the second bypass flow path 26b do not need to intersect, which helps reduce the structural complexity of the flow channel plate 20 and simplify its structure.

[0054] Continue to refer Figure 7 and Figure 8 The plurality of valve interfaces 23 may further include a fifth valve interface 23e, which is located between the third valve interface 23c and the fourth valve interface 23d. The orthographic projection of the second bypass channel 26b on the plane where the plurality of valve interfaces 23 are located, that is, on the plane perpendicular to the axis AA, may at least partially overlap with the fifth valve interface 23e. For ease of understanding, the overlapping portion is shown in FIG. Figure 8 According to this structure, the second bypass flow channel 26b will occupy the back space of the fifth valve interface 23e, ensuring that the second bypass flow channel 26b has a larger width and a smaller flow resistance.

[0055] Continue to refer Figure 7 and Figure 8 The channel wall of the first bypass channel 26a can include an extension portion 27a located in the middle region. The extension portion 27a can be in a smooth arc shape. When the fluid medium in the first bypass channel 26a flows through the middle region, it is guided by the channel wall extension portion 27a. According to the above configuration, the balanced arc-shaped extension portion 27a helps reduce flow resistance and suppress turbulence.

[0056] In some embodiments, the flow channel plate 20 may also be provided with a communication port 241, which may span the flow channel wall 27 between the first main flow channel 25a and the other main flow channel 25c adjacent thereto, and the first pipe interface 24a may be connected to both the first main flow channel 25a and the other main flow channel 25c through the communication port 24. Through the communication port 241 spanning the first main flow channel 25a and the other main flow channel 25c, the first pipe interface 24a is connected to both the first main flow channel 25a and the other main flow channel 25c. In this way, the first pipe interface 24a can not only be connected to the first valve interface 23a and the second valve interface 23b through the first main flow channel 25a and the first bypass flow channel 26a, but can also be connected to the other valve interface 23f through the other main flow channel 25c. In this way, one pipe interface 24a is connected to at least three valve interfaces 23a, 23b, and 23f, so that the flow channel plate 20 and the multi-way valve 10 can collaboratively provide more working modes to meet more complex or diverse connection requirements.

[0057] refer to Figure 5 and Figure 9, the flow channel plate 20 may include a first plate body 21 and a second plate body 22. A plurality of valve interfaces 23 may be provided on the side of the first plate body 21 facing away from the second plate body 22. A protruding first wall portion 211 may be provided on the side of the first plate body 21 facing the second plate body 22, and a protruding second wall portion 212 may be provided on the side of the second plate body 22 facing the first plate body 21. The first wall portion 211 and the second wall portion 212 may be matched to form at least one main flow channel 25 and at least one bypass flow channel 26. According to this structure, the two plate bodies 211 and 212 can be formed separately by injection molding or the like, and then the two plate bodies 211 and 212 can be assembled (hot plate welding) together to form a flow channel plate 20 with multiple flow channels 25 and 26 inside. Therefore, the flow channel plate 20 with this structure is easy to manufacture.

[0058] It can be understood that in other examples, the flow channel plate 20 can also be formed in one piece, or the flow channel plate 20 can be composed of three or more plate bodies assembled together.

[0059] It should be noted that the various elements described in the above specific embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0060] It should be understood that multiple components and / or parts can be provided by a single integrated component or part. Alternatively, a single integrated component or part can be divided into separate multiple components and / or parts. The disclosure "a" or "an" used to describe a component or part does not mean to exclude other components or parts.

[0061] It should be understood that although the terms "first" or "second" etc. may be used in this disclosure to describe various elements (such as a first valve interface and a second valve interface), these elements are not defined by these terms, which are merely used to distinguish one element from another.

[0062] The basic principles of the present disclosure have been described above in conjunction with specific embodiments. However, it should be noted that the advantages, strengths, and effects mentioned in this disclosure are merely illustrative and not restrictive, and should not be construed as necessarily possessed by each embodiment of the present disclosure.
