Description

Technical Field

[0001] This application relates to the field of diversion system technology, specifically a temperature control system, a vehicle, an energy storage system, and a multi-way valve. Background Technology

[0002] With the booming development of industries such as new energy vehicles and energy storage stations, the importance and complexity of temperature control systems are gradually increasing, especially the complexity of liquid pipelines. For example, the functional modules that may utilize liquid pipelines in an energy storage system include: battery cooling, battery heat pump heating, battery thermistor heating, power conversion system (PCS) cooling, and energy storage cabinet dehumidification. In the automotive field, this also involves motor cooling, passenger compartment cooling, and heating. To achieve temperature control of different locations throughout the entire device using a single temperature control system, multi-way valves are typically installed in the liquid cooling pipelines of the temperature control system to achieve flow diversion, merging, or regulation of the liquid flow path within the pipelines.

[0003] However, existing multi-way valves typically consist of a valve body and a valve core. The curved surfaces of the valve body and valve core make them prone to internal leakage. Furthermore, the large contact area results in significant friction, placing higher demands on the torque required for the actuators. Summary of the Invention

[0004] This application provides a temperature control system, a vehicle, an energy storage system, and a multi-way valve, which helps to reduce the risk of leakage in the temperature control system.

[0005] In a first aspect, this application provides a temperature control system, comprising an actuator, multiple liquid lines, and a multi-way valve. The multiple liquid lines are respectively used to transmit coolant to one or more heating elements, thereby controlling the temperature of the heating elements. The liquid lines are connected to the multi-way valve, and the actuator is used to drive the multi-way valve to move according to the temperature of one or more liquid lines or heating elements. The actuator drives the multi-way valve to adjust its operating mode, allowing the liquid lines to have different connection schemes. Specifically, the multi-way valve includes a first valve body and a second valve body. The first valve body includes a first plane, and the second valve body includes a second plane. The first and second planes are parallel and fit together. The actuator is used to drive the first and second planes to rotate relative to each other around the rotation axis of the multi-way valve according to the temperature of one or more liquid lines or heating elements. The first plane includes multiple sets of first fan-ring openings, each set of first fan-ring openings including two spaced-apart first fan-ring openings. The multiple first fan-ring openings are divided into multiple rings around the rotation axis and arranged at intervals. Two first fan-ring openings in each set are connected through an internal channel of the first valve body. The aforementioned second plane includes multiple sets of second annular openings. Each set of second annular openings includes multiple spaced-apart second annular openings, arranged in a ring around the rotation axis. Each second annular opening connects to at least one first annular opening and, through the internal channel of the second valve body, connects to at least one liquid pipeline. In this technical solution, the first and second valve bodies are mated by a planar fit, resulting in reliable contact between the planes and reducing the likelihood of leakage. Furthermore, both the first and second valve bodies have internal channels, which are themselves less prone to leakage, and the channels themselves are less likely to experience cross-flow leakage, further reducing the probability of leakage in the multi-way valve.

[0006] In the specific technical solution, the central angle of each first fan-ring opening is equal to a preset angle value. At least one second fan-ring opening in each group includes one or more radial baffles. At least one second fan-ring opening is divided into at least two fan-ring opening segments by the radial baffles, and the central angle of each fan-ring opening segment is equal to the preset angle value. Each fan-ring opening segment is used to communicate with one first fan-ring opening. When the aforementioned second fan-ring opening is divided into at least two fan-ring opening segments by the radial baffles, flow splitting or merging can be achieved. Alternatively, when the multi-way valve adjusts its operating mode, that is, when the first valve body is driven to rotate relative to the second valve body, the aforementioned second internal channel can still be connected to the same first internal channel in different operating modes.

[0007] When specifically setting the aforementioned radial baffles, each of the aforementioned radial baffles is fixed to the second valve ring opening radially along the second valve ring opening. The specific fixing method of the aforementioned radial baffles is not limited. For example, the radial baffles can be integrally formed with the second valve body, or the aforementioned radial baffles can be fixedly connected to the second valve body by welding or bonding processes.

[0008] In another specific technical solution, the difference between the inner and outer diameters of each second fan-ring opening is equal to a preset length value. At least one of the first fan-ring openings includes a circumferential baffle plate, which divides the second fan-ring opening into two layers of fan-ring openings. The difference between the inner and outer diameters of each layer of fan-ring openings is equal to the preset length value. Each layer of fan-ring opening is used to communicate with one second fan-ring opening. When the first fan-ring opening is divided into at least two layers of fan-ring openings by the circumferential baffle plate, flow splitting or merging can be achieved. Alternatively, when the multi-way valve adjusts its operating mode, that is, when the first valve body is driven to rotate relative to the second valve body, the first internal channel can still communicate with the same second internal channel in different operating modes.

[0009] When specifically setting the aforementioned circumferential baffles, each circumferential baffle is fixed to the opening of the first annular ring along the circumference of the opening. The specific fixing method of the aforementioned circumferential baffles is not limited; for example, the circumferential baffles can be integrally formed with the first valve body, or the aforementioned circumferential baffles can be fixedly connected to the first valve body through welding or bonding processes.

[0010] In the specific technical solution, the first plane includes multiple rings of first fan-ring openings, which include a first ring of first fan-ring openings, a second ring of first fan-ring openings, a third ring of fan-ring openings, and a fourth ring of fan-ring openings arranged sequentially along the direction away from the rotation axis; the second plane includes multiple sets of second fan-ring openings, which include a first set of second fan-ring openings, a second set of second fan-ring openings, a third set of second fan-ring openings, and a fourth set of second fan-ring openings arranged sequentially along the direction away from the rotation axis; each ring of first fan-ring openings is located in the same ring, and each set of second fan-ring openings is located in the same ring; the rings containing the multiple sets of second fan-ring openings correspond one-to-one with the rings containing the multiple rings of first fan-ring openings; each second fan-ring opening is used to communicate with the first fan-ring opening located in the same ring.

[0011] The following lists several arrangements of the first sector opening on the first plane and the second sector opening on the second plane.

[0012] In one arrangement, a first plane includes a first ring first fan ring opening, the first ring first fan ring opening includes six first fan ring openings, the six first fan ring openings are respectively located in five groups of first fan ring openings; a second plane includes a first group of second fan ring openings, the first group of second fan ring openings includes four second fan ring openings, each second fan ring opening in the first group of second fan ring openings includes a radial baffle, and each second fan ring opening in the first group of second fan ring openings is used to communicate with any first fan ring opening in the first ring first fan ring opening.

[0013] In another arrangement, the first plane includes a second ring with a first fan-ring opening, the second ring with a first fan-ring opening including four first fan-ring openings, the four first fan-ring openings being located in three groups of first fan-ring openings respectively; the second plane includes a second group of second fan-ring openings, the second group of second fan-ring openings including two second fan-ring openings, one of the second fan-ring openings of the second group of second fan-ring openings including a radial baffle, the other second fan-ring opening of the second group of second fan-ring openings including two radial baffles; each second fan-ring opening in the second group of second fan-ring openings is used to communicate with any first fan-ring opening in the second ring with a first fan-ring opening.

[0014] In another arrangement, the first plane includes a third ring first fan ring opening, which includes four first fan ring openings located in three groups of first fan ring openings; the second plane includes a third group of second fan ring openings, which includes three second fan ring openings, and two of the second fan ring openings in the third group include two radial baffles; each second fan ring opening in the third group is used to communicate with any one of the first fan ring openings in the third ring first fan ring opening.

[0015] In another arrangement, the first plane includes a fourth ring first fan ring opening, the fourth ring first fan ring opening includes two first fan ring openings, the two first fan ring openings are respectively located in two groups of first fan ring openings; the second plane includes a fourth group of second fan ring openings, the fourth group of second fan ring openings includes one second fan ring opening, the second fan ring opening in the fourth group of second fan ring openings includes two radial baffles; each second fan ring opening in the fourth group of second fan ring openings is used to communicate with any first fan ring opening in the fourth ring first fan ring opening.

[0016] Specifically, when configuring the second valve body, at least one end of the second internal channel has at least two third fan-ring openings, and any liquid pipeline connected to any of these third fan-ring openings is connected to the corresponding second internal channel. In this embodiment, different liquid pipelines can be connected to the second internal channel, enriching the application scenarios of the multi-way valve.

[0017] In implementing the multi-way valve in the embodiments of this application, the specific structure is not limited. In one technical solution, the first valve body is a cylindrical valve body, and the second valve body includes a first end cap, a second end cap, and a cylinder. The first and second end caps are connected to the two ends of the cylinder, and a second internal channel is located in the first end cap. The first end cap, the second end cap, and the cylinder enclose a cylindrical mounting cavity, and the cylindrical valve body is mounted in the cylindrical mounting cavity. The outer surface of the cylindrical valve body fits against the cylindrical mounting cavity, and the first plane fits against the second plane. Under the drive of the actuator, the first valve body rotates within the cylindrical mounting cavity. In this solution, the first valve body is assembled in the cylindrical mounting cavity formed by the second valve body, resulting in a better sealing effect and reducing the likelihood of leakage.

[0018] Secondly, this application also provides a vehicle. The vehicle includes a battery pack and the aforementioned temperature control system from the first aspect. At least one liquid line in the temperature control system is thermally bonded to the battery pack. The battery pack acts as a heat-generating device, and the liquid lines are used to transfer coolant to the battery pack, enabling the temperature control system to control the temperature of the battery pack.

The battery pack acts as a heat-generating device, and the liquid lines are used to transfer coolant to the battery pack, enabling the temperature control system to control the temperature of the battery pack. The temperature control system in this energy storage system is less prone to leakage.

[0020] Fourthly, this application also provides a multi-way valve. The multi-way valve includes a first valve body and a second valve body, wherein: the first valve body includes a first plane, the second valve body includes a second plane, the first and second planes are parallel to each other and fit together, multiple liquid lines are respectively used to transmit coolant to one or more heating devices, and an actuator is used to drive the first and second planes to rotate relative to each other around the rotation axis of the multi-way valve according to the temperature of one or more liquid lines or heating devices, wherein: the first plane includes multiple sets of first fan-ring openings, each set of first fan-ring openings includes two spaced-apart first fan-ring openings, the multiple first fan-ring openings are divided into multiple rings around the rotation axis and arranged at intervals, and two first fan-ring openings in each set are connected through an internal channel of the first valve body; the second plane includes multiple sets of second fan-ring openings, each set of second fan-ring openings includes multiple spaced-apart second fan-ring openings, each set of second fan-ring openings is arranged in a ring around the rotation axis, and each second fan-ring opening is used to connect to at least one first fan-ring opening and to at least one liquid line through the internal channel of the second valve body.

[0043] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.

[0045] Furthermore, the descriptions such as "first," "second," and "third" in the embodiments of this application are merely for distinguishing different specific structures, while the structures may have the same characteristics.

[0046] It should be noted that specific details are set forth in the following description to provide a full understanding of this application. However, this application can be implemented in many ways other than those described herein, and those skilled in the art can make similar extensions without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below. The following descriptions are preferred embodiments for carrying out this application; however, these descriptions are for the purpose of illustrating the general principles of this application and are not intended to limit the scope of this application. The scope of protection of this application shall be determined by the appended claims.

[0047] To facilitate understanding of the temperature control system, vehicle, energy storage system, and multi-way valve provided in this application embodiment, their application scenarios are described below. The temperature control system can specifically be a liquid cooling system, heating system, or hydraulic system, etc. In short, this temperature control system includes multiple liquid pipelines, involving liquid diversion and convergence between these pipelines, requiring pipelines to regulate liquid flow. For example, the temperature control system in a vehicle or energy storage system can adopt the temperature control system described in this application embodiment. Specifically, the vehicle temperature control system can be used to control the temperature of the vehicle's battery pack, and the energy storage system temperature control system can be used to control the temperature of the energy storage system's battery pack. Furthermore, the above-mentioned temperature control system can also be applied to electronic devices such as computer rooms or servers. In the prior art, this can be achieved by setting up a valve group formed by multiple three-way valves. However, this solution results in a more complex control process, more connecting components, and a higher risk of leakage. In addition, it also leads to a larger valve group size in the temperature control system, occupying more space.

[0048] Figure 1 This diagram illustrates two topologies of the temperature control system in this application. The temperature control system includes a driver, multiple liquid lines, and a multi-way valve 900, with the liquid lines connected to the multi-way valve 900. At least one liquid line carries a battery pack 100, and at least one of the multiple liquid lines is thermally bonded to the battery pack, thereby enabling the temperature control system to control the temperature of the battery pack. Specifically, the temperature control system can dissipate heat or heat the battery pack according to the actual working environment, ensuring the battery pack operates under suitable temperature conditions.

[0049] like Figure 1As shown in (a) above, in a specific embodiment, the liquid pipeline of the above-mentioned temperature control system includes a heat exchange circuit 300, a heating circuit 400, a first cooling circuit 500, a second cooling circuit 600, a battery pack temperature control circuit 700, and a load temperature control circuit 800. At least one liquid pipeline has a heat exchanger, which is specifically located on the heat exchange circuit 300 including the compressor. The above-mentioned temperature control system can also be used to control the temperature of the load 200. In this embodiment, the multi-way valve 900 is a ten-way valve. The above-mentioned temperature control system includes a heat exchange circuit 300, a heating circuit 400, a first cooling circuit 500, a second cooling circuit 600, a battery pack temperature control circuit 700, and a load temperature control circuit 800. The heating circuit 400 and the first cooling circuit 500 are respectively connected to the heat exchange circuit 300 for heat exchange. For example, the heating circuit 400 exchanges heat with the heat exchange circuit 300 through a heat exchanger, and the first cooling circuit 500 exchanges heat with the heat exchange circuit 300 through another heat exchanger. The aforementioned battery pack temperature control circuit 700 is thermally connected to the battery pack 100 and is used to control the temperature of the battery pack 100. The load temperature control circuit 800 is thermally connected to the load 200 and is used to control the temperature of the load 200. The aforementioned first cooling circuit 500, second cooling circuit 600, battery pack temperature control circuit 700, and load temperature control circuit 800 are respectively connected to the valve port of multi-way valve 900. The driver drives multi-way valve 900 to rotate, thereby controlling multi-way valve 900 according to the actual application scenario, so that different circuits are connected and the temperature control system is in different working modes.

[0050] like Figure 1 As shown in (b) above, in another specific embodiment, the multi-way valve 900 is an eight-way valve. This embodiment is similar to... Figure 1 The only difference in the embodiment shown in (a) is that it does not include load 200 and load temperature control circuit 800.

[0051] This application also provides a vehicle in which the aforementioned temperature control system can be a vehicle temperature control system. Specifically, the vehicle includes at least a battery pack and the aforementioned temperature control system. The battery pack is equivalent to the vehicle's heat-generating device, and at least one liquid line in the temperature control system is thermally bonded to the battery pack for controlling the temperature of the vehicle's battery pack.

[0052] In addition, this application also provides an energy storage system, wherein the temperature control system can also be a temperature control system for an energy storage system. The energy storage system includes at least a battery pack and the temperature control system. The battery pack is equivalent to a heating element of the energy storage system. At least one liquid pipeline in the temperature control system is thermally bonded to the battery pack for controlling the temperature of the battery pack of the energy storage system.

[0053] In the embodiments of this application, "used for" refers to the capability of a structure, which is different from the actual connection relationship. For example, "A is used for B" means that A has the relevant capability and can perform the function of B. However, in reality, in a certain scenario, or in various scenarios, A may not perform the aforementioned function of B.

[0054] Figure 2 This is a schematic diagram of a multi-way valve in one embodiment of this application, such as... Figure 2 As shown, the multi-way valve 900 includes a first valve body 1 and a second valve body 2. The first valve body 1 includes a first plane 11, and the second valve body 2 includes a second plane 21. During assembly, the first valve body 1 and the second valve body 2 are mounted relative to each other around a rotation axis, such that the first plane 11 and the second plane 21 are parallel and in contact with each other. This design allows the first valve body 1 and the second valve body 2 of the multi-way valve 900 to achieve a reliable contact between the planes through planar fit, reducing the likelihood of leakage.

[0055] Figure 3 This is a schematic diagram of one structure of the first valve body in an embodiment of this application. Figure 4 This is a top view schematic diagram of the first valve body in an embodiment of this application. Figure 3 and Figure 4 As shown, the first plane 11 of the first valve body 1 includes multiple sets of first fan-ring openings 111. Each set of first fan-ring openings 111 includes two spaced-apart first fan-ring openings 111. The multiple first fan-ring openings 111 are divided into multiple rings around the rotation axis and arranged at intervals. Two first fan-ring openings 111 in each set are connected through an internal channel of the first valve body 1. For ease of description, the internal channel of the first valve body 1 is referred to as the first internal channel 112 in the following embodiments. The first valve body 1 includes multiple first internal channels 112, and the two ends of the first internal channel 112 are the first fan-ring openings 111. Each of the first fan-ring openings 111 connected by the first internal channel 112 constitutes a set of first fan-ring openings 111. In one embodiment, the first fan-shaped opening 111 at one end of the first internal channel 112 is located on the first plane 11, and the first fan-shaped opening 111 at the other end of the first internal channel 112 is also located on the first plane 11. The first fan-shaped openings 111 at both ends of each first internal channel 112 are connected through the first internal channel 112. The plurality of first fan-shaped openings 111 are arranged on different rings centered on the rotation axis on the first plane 11. Figure 3 and Figure 4 In the embodiment shown, the first plane 11 includes two rings, one of which has an inner diameter larger than the other, such that the two rings do not overlap in the radial direction, and each ring is provided with two first fan-shaped openings 111.

[0056] Figure 5 This is a cross-sectional view of the second valve body in one embodiment of this application. Figure 6 This is a top view schematic diagram of the second valve body in an embodiment of this application. For example... Figure 5 and Figure 6 As shown, the second plane 21 of the second valve body 2 includes multiple sets of second fan-ring openings 211. Each set of second fan-ring openings 211 includes multiple spaced-apart second fan-ring openings 211, and each set of second fan-ring openings 211 is arranged in a ring around the rotation axis. The second valve body 2 includes multiple internal channels. For ease of description, the internal channels of the second valve body 2 are referred to as second internal channels 212 in the following embodiments. One end of the second internal channel 212 is a second fan-ring opening 211, which is located on the second plane 21. The other end of the second internal channel 212 is a third fan-ring opening 213, which is located on the side of the second valve body 2 opposite to the second plane 21. In one embodiment, one end of the second internal channel 212 is a second fan-ring opening 211, and the other end is a third fan-ring opening 213. The second fan-ring opening 211 and the third fan-ring opening 213 are connected through the second internal channel 212. Each second annular opening 211 is used to connect to at least one liquid conduit through the second internal channel 212. Specifically, the aforementioned third annular opening 213 is connected to at least one liquid conduit, thereby connecting the second annular opening to at least one liquid conduit through the second internal channel 212, thus enabling communication between the liquid conduit and the second internal channel 212. In a specific embodiment, second annular openings 211 located in the same ring form a group of second annular openings 211, such as... Figure 5 In the illustrated embodiment, the second surface includes two annular rings, each annular ring having two second sector-ring openings 211, and these two second sector-ring openings 211 form a group. Figure 5 In the specific embodiment shown, the multi-way valve includes two sets of second fan ring openings 211, each set of fan ring openings includes two second fan ring openings 211, and the two second fan ring openings 211 are arranged at intervals.

[0057] In a specific embodiment, at least one end of the second internal channel 212 has at least two third fan-shaped openings 213. A liquid conduit communicating with any one of the third fan-shaped openings 213 is also connected to the corresponding second internal channel 212. That is, a second internal channel 212 can connect to one, two, or more liquid conduits.

[0058] Figure 7 This is a schematic diagram of a multi-way valve in one embodiment of this application, such as... Figure 7As shown in the specific embodiment, when the first valve body 1 and the second valve body 2 of the multi-way valve are assembled, the first plane 11 and the second plane 21 are parallel and fit together, achieving a planar seal between the first valve body 1 and the second valve body 2. Each second sector ring opening 211 is used to communicate with at least one first sector ring opening 111, and each first internal channel 112 is used to communicate with two or more second internal channels 212, which are connected to liquid pipelines. By adjusting the relative position of the first valve body 1 and the second valve body 2, the second sector ring opening 211 can be connected to different first sector ring openings 111, thereby adjusting the connection or disconnection of different liquid pipelines.

[0059] The aforementioned actuator is used to drive the first plane 11 and the second plane 21 to rotate relative to each other around the rotation axis of the multi-way valve according to the temperature of one or more liquid lines or heating devices, thereby adjusting the temperature control scheme of the temperature control system. In one embodiment, the second valve body 2 can be relatively fixed, and the actuator is connected to the first valve body 1 to drive the first valve body 1 to rotate relative to the second valve body 2 around the aforementioned rotation axis. Since the third sector opening 213 of the second valve body 2 is connected to the liquid line, driving the first valve body 1 to rotate is relatively convenient. The annulus containing the plurality of the aforementioned first sector openings 111 is the same as the annulus containing the second sector openings 211. For example Figures 3 to 7 In the illustrated embodiment, the first sector ring opening 111 is arranged on two rings of the first plane 11, and the second sector ring opening 211 is arranged on two rings of the second plane 21. Since the two rings arranged by the first sector ring opening 111 are the same as the two rings arranged by the second sector ring opening 211, each second sector ring opening 211 is connected to different first sector ring openings 111 located on the same ring.

[0060] In this embodiment, a flow channel is formed using a first internal channel 112 located inside the first valve body 1 and a second internal channel 212 located inside the second valve body 2. Since the first internal channel 112 and the second internal channel 212 are not prone to leakage, and cross-flow leakage between the channels is unlikely, no additional sealing structure is needed between the first internal channels 112 and the second internal channels 212, further reducing the probability of leakage in the multi-way valve. Because the first valve body 1 and the second valve body 2 are sealed by contact between the first plane 11 and the second plane 21, the contact area is small. When adjusting the relative position of the first valve body 1 and the second valve body 2, the friction between the first plane 11 and the second plane 21 is small, resulting in lower power requirements for the drive device and reducing the energy consumption of the multi-way valve.

[0061] In a specific embodiment, the first valve body 1 and the second valve body 2 can be made of metal or plastic, and can be formed by injection molding or casting.

[0062] Please refer to Figure 4 and Figure 6 In one embodiment, the central angle α of each first sector ring opening 111 is equal to a preset angle value, and the central angle β of each second sector ring opening 211 is equal to a preset angle value. In this embodiment, the driver drives the first valve body 1 and the second valve body 2 to rotate relative to each other around the rotation axis. Specifically, the driver drives the first valve body 1 to rotate around the rotation axis by a preset angle value or an integer multiple of the preset angle value, so that the first sector ring opening 111 is connected to different second sector ring openings 211, and at least one first internal channel 112 is connected to different second internal channels 212.

[0063] In one embodiment, when the first valve body 1 rotates relative to the second valve body 2 about the axis of rotation by a preset angle value or an integer multiple of the preset angle value, the plane between the first fan ring openings 111 of the first plane 11 and the plane between the second fan ring openings 211 of the second plane 21 come into contact with each other to form a sealing structure, so as to ensure the sealing performance of the multi-way valve.

[0064] Figure 8 This is a schematic diagram of the structure of the second valve body in one embodiment of this application. Please refer to it. Figure 7 and Figure 8 In a specific embodiment, the first valve body 1 is a cylindrical valve body, and the second valve body 2 includes a first end cap 22, a second end cap 23, and a cylinder 24. The first end cap 22 and the second end cap 23 are connected to the two ends of the cylinder 24, and the second internal channel 212 is located in the first end cap 22. The first end cap 22, the second end cap 23, and the cylinder 24 enclose a cylindrical mounting cavity, and the cylindrical valve body is installed in the cylindrical mounting cavity. The outer surface of the cylindrical valve body is in contact with the cylindrical mounting cavity, and the first plane 11 is in contact with the second plane 21. In this embodiment, the first valve body 1 rotates within the cylindrical mounting cavity under the drive of the actuator. The second valve body 2 has a cylindrical mounting cavity, which can serve as a sealing structure for the multi-way valve, ensuring that the first plane 11 and the second plane 21 are in contact without leakage. In this solution, the multi-way valve achieves sealing itself without the need for other structural components, and the sealing effect is good. When assembling a multi-way valve, simply connect the second valve body 2 to the liquid pipeline; the assembly is relatively simple.

[0065] In implementing the above solution, the first end cap 22 and the cylinder 24 can be integrally formed. In this solution, there is no connecting gap between the first end cap 22 and the cylinder 24, which reduces the structure that the second valve body 2 needs to assemble and seal, simplifies assembly, and reduces the risk of leakage.

[0066] In a specific embodiment, the aforementioned first internal channels are interlaced within the first valve body 1 but are not interconnected. Furthermore, in one embodiment, the different first sector openings 111 of the aforementioned first plane 11 have the same area, thereby reducing flow resistance. Additionally, the different second sector openings 211 of the aforementioned second plane 21 also have the same area. The different third sector openings 213 of the aforementioned second valve body 2 have the same area, which, in addition to reducing flow resistance, also facilitates the standardization of the external interface of the multi-way valve. Furthermore, in one embodiment, the areas of the aforementioned first sector opening 111, second sector opening 211, and third sector opening 213 are the same.

[0067] It is worth noting that the "multiple" mentioned in the embodiments of this application refers to at least two, that is, two or more cases.

[0068] The above embodiments use a two-position four-way valve as an example to illustrate part of the technical solution of this application. To make the details of the solution clearer, a four-position ten-way valve is used as an example below to illustrate part of the technical solution of this application.

[0069] Figure 9 This is a schematic diagram of a structure of the first plane in an embodiment of this application, such as... Figure 9 As shown, the first plane 11 includes seven sets of first fan-ring openings 111, each set of first fan-ring openings 111 represented by a different line type. Furthermore, each set of first fan-ring openings 111 is connected by a first internal flow channel. In this embodiment, the multiple first fan-ring openings 111 are distributed in four different rings. Figure 10 This is a schematic diagram of a structure of the second plane in an embodiment of this application, such as... Figure 10 As shown, the second plane 21 includes four sets of second fan-ring openings 211, each set of second fan-ring openings 211 arranged in a ring, so the multiple second fan-ring openings 211 of the second plane 21 are arranged in four rings. The four rings of the second plane 21 are the same as the four rings of the first plane 11, so the second fan-ring openings 211 located in the same ring can communicate with any first fan-ring opening 111 located in the same ring.

[0070] Please refer to Figure 9 The central angle α of each first sector opening 111 is equal to a preset angle value. Figure 11 This is a partial cross-sectional view of the second valve body in an embodiment of this application. Please refer to the diagram below. Figure 10 and Figure 11 In one embodiment, at least one second fan-ring opening 211 in each group of second fan-ring openings 211 includes one or more radial baffles 25, and the at least one second fan-ring opening 211 is divided into at least two fan-ring opening segments by the radial baffles 25. Specifically, the radial baffles 25 extend radially and divide the second fan-ring opening 211 circumferentially into at least two fan-ring opening segments, such as... Figure 11 In the illustrated embodiment, a radial partition plate divides a second fan-ring opening 211 into three fan-ring opening segments. At least two fan-ring opening segments formed by the same second fan-ring opening 211 communicate with the same second internal flow channel, and the central angle β of each fan-ring opening segment is equal to a preset angle value. In actual operation, a certain fan-ring opening segment of the second fan-ring opening 211 is used to communicate with the first fan-ring opening 111. Since both the aforementioned central angle α and central angle β are preset angle values, the aforementioned central angle α and central angle β are equal. When achieving communication between the first fan-ring opening 111 and a certain fan-ring opening segment of the second fan-ring opening 211, the first fan-ring opening 111 can be matched with the aforementioned fan-ring opening segment of the second fan-ring opening 211, ensuring reliable communication between the first fan-ring opening 111 and the second fan-ring opening 211.

[0071] When the actuator drives the first valve body 1 and the second valve body 2 to rotate relative to each other around the rotation axis, driving the first valve body 1 to rotate around the rotation axis by a preset angle value or an integer multiple of the preset angle value allows the first sector ring opening 111 to connect with a segment of the sector ring opening 211 of different second sector ring openings, and at least one first internal channel 112 to connect with different second internal channels 212. In this scheme, using the actuator to drive the first valve body 1 to rotate facilitates automated adjustment. Furthermore, when driving the first valve body 1 and the second valve body 2 to rotate relative to each other around the rotation axis, the preset angle value can be rotated each time, or the first valve body 1 and the second valve body 2 can be driven to rotate relative to each other in steps of the preset angle value, which simplifies the control process of the multi-way valve.

[0072] Specifically, when setting the aforementioned radial baffles 25, each radial baffle 25 is fixed to the second annular opening 211 radially. The specific fixing method of the aforementioned radial baffles 25 is not limited; for example, the radial baffles 25 can be integrally formed with the second valve body 2, or the aforementioned radial baffles 25 can be fixedly connected to the second valve body 2 through welding or bonding processes.

[0073] When the second fan-ring opening 211 is divided into at least two fan-ring openings by the radial baffle 25, flow splitting or merging can be achieved. Alternatively, when the multi-way valve adjusts its operating mode, that is, when the first valve body 1 is driven to rotate relative to the second valve body 2, the first internal channel 112 can still be connected to the same second internal channel 212 in different operating modes.

[0074] Please continue to refer to this. Figure 9 and Figure 10 In one embodiment, the difference L1 between the inner and outer diameters of each second fan ring opening 211 is equal to a preset length value. Figure 12 This is a partial cross-sectional view of the first valve body in an embodiment of this application. Please refer to the diagram below. Figure 9 and Figure 12At least one of the first fan-ring openings 111 includes a circumferential baffle 12, which divides the second fan-ring opening 211 into two layers of fan-ring openings. Specifically, the circumferential baffle 12 extends circumferentially and radially divides the first fan-ring opening 111 into at least two layers of fan-ring openings. The two layers of fan-ring openings are connected to the same first internal flow channel, and the second fan-ring opening 211 is connected to any layer of the first fan-ring opening 111, all connected to the same first internal flow channel. The difference between the inner and outer diameters L2 of each layer of fan-ring openings is equal to a preset length value. When the second fan-ring opening 211 is connected to a certain layer of the first fan-ring opening 111, the second fan-ring opening 211 can be matched with a certain layer of the first fan-ring opening 111, so that the first fan-ring opening 111 and the second fan-ring opening 211 are reliably connected.

[0075] Specifically, when setting the aforementioned circumferential baffles 12, each circumferential baffle 12 is fixed to the first annular opening 111 along the circumference of the first annular opening 111. The specific fixing method of the aforementioned circumferential baffles 12 is not limited. For example, the circumferential baffles 12 can be integrally formed with the first valve body 1, or the aforementioned circumferential baffles 12 can be fixedly connected to the first valve body 1 by welding or bonding processes.

[0076] When the first fan ring opening 111 is divided into at least two fan ring openings by the circumferential baffle 12, it can achieve flow splitting or flow merging. Or when the multi-way valve adjusts its working mode, that is, when it drives the first valve body 1 to rotate relative to the second valve body 2, it can make the second internal channel 212 still connected to the same first internal channel 112 in different working modes.

[0077] Please refer to Figure 9 and Figure 10 The first plane 11 can be considered as divided into multiple first sector-shaped regions centered on the rotation axis. Each first sector opening 111 is located within a first sector region, but not simultaneously within two or more first sector regions. Adjacent first sector regions are separated by a first dividing zone, which separates adjacent first sector openings 111 circumferentially. Similarly, the second plane 21 can be considered as divided into multiple second sector-shaped regions centered on the rotation axis. Each second sector opening 211, after being separated by the radial baffle 25, is located within a second sector region, but not simultaneously within two or more second sector regions. Adjacent second sector regions are separated by a second dividing zone, which separates different segments of sector openings circumferentially. The center angles of the first and second sector regions are the same, specifically the preset angle value. Therefore, each time the first valve body 1 rotates, the first dividing zone and the second dividing zone will come into contact to form a sealing structure.

[0078] It is worth noting that the annular and fan-shaped regions mentioned in the embodiments of this application are virtual structures, and there are no actual corresponding structures.

[0079] Please continue to refer to this. Figure 9 In a specific embodiment, the first plane includes multiple rings of first sector openings 111, each ring of first sector openings 111 arranged in a circle, and the multiple rings of first sector openings 111 are arranged sequentially in a direction away from the rotation axis. In other words, the distance between the first sector opening 111 of each ring and the rotation axis is the same, while the distance between the first sector opening 111 of different rings and the rotation axis is different.

[0080] Please continue to refer to this. Figure 10 In a specific embodiment, the second plane includes multiple sets of second fan-shaped openings 211, which are arranged sequentially along a direction away from the rotation axis. Each set of second fan-shaped openings 211 is arranged around the rotation axis of the first plane 11 or the second plane 21, and the distance between each set of second fan-shaped openings 211 and the rotation axis of the first plane 11 or the second plane 21 is not the same. Each second fan-shaped opening 211 in each set is equidistant from the rotation axis of the first plane 11 or the second plane 21. Alternatively, each set of second fan-shaped openings 211 is located in the same ring centered on the aforementioned rotation axis, but each set of second fan-shaped openings 211 is located in different rings.

[0081] The first sector opening 111 of each ring is located in the same ring, and the second sector opening 211 of each group is located in the same ring; the rings containing the multiple groups of second sector openings 211 correspond one-to-one with the rings containing the first sector openings 111 of the multiple rings; each second sector opening 211 is used to communicate with the first sector opening 111 located in the same ring. Specific embodiments are described below.

[0082] In the above embodiments, the distance between the fan ring opening and the rotation axis can be considered as the distance between the inner edge of each fan ring opening closest to the rotation axis and the rotation axis, or the distance between the outer edge of each fan ring opening furthest from the rotation axis and the rotation axis. In short, when comparing the above distances of different fan ring openings, a unified standard should be used. For example, the distance between the inner edge of one fan ring opening closest to the rotation axis and the rotation axis should not be compared with the distance between the outer edge of another fan ring opening furthest from the rotation axis and the rotation axis.

[0083] In specific embodiments, please refer to Figure 9 and Figure 10The aforementioned first plane has multiple rings of first fan-ring openings 111, including a first ring of first fan-ring openings 111, a second ring of first fan-ring openings 111, a third ring of fan-ring openings, and a fourth ring of fan-ring openings arranged sequentially along the direction away from the rotation axis. The aforementioned second plane has multiple sets of second fan-ring openings 211, including a first set of second fan-ring openings 211, a second set of second fan-ring openings 211, a third set of second fan-ring openings 211, and a fourth set of second fan-ring openings 211 arranged sequentially along the direction away from the rotation axis.

This third group of second fan-ring openings 211 includes three second fan-ring openings 211. Two of the second fan-ring openings 211 in the third group include two radial baffles 25, and this second fan-ring opening 211 includes three fan-ring opening segments. The other second fan-ring opening 211 in the third group does not have a radial baffle 25 and is itself an independent fan-ring opening. The first sector opening 111 of the third ring and the second sector opening 211 of the third group are located in the same ring. The first sector opening 111 of the third ring includes four first sector openings 111, which are respectively located in the three groups of first sector openings 111. Each second sector opening 211 in the third group of second sector openings 211 is used to communicate with any one of the first sector openings 111 in the first sector opening of the third ring.

[0088] The aforementioned fourth group of fan ring openings is located on the outer periphery of the second fan ring opening 211 of the third group, and is radially adjacent to the second fan ring opening 211 of the third group. The distance between each second fan ring opening 211 in the fourth group and the rotation axis is greater than the distance between each second fan ring opening 211 in the third group and the rotation axis. The fourth group of second fan ring openings 211 includes one second fan ring opening 211, and the third fan ring opening 213 in the fourth group of second fan ring openings 211 includes two radial baffles 25.
