Description

Technical Field

[0001] This application relates to the field of thermal management technology for electric new energy vehicles, and in particular to a mechanical three-way valve, a thermal management integrated module, and a new energy vehicle. Background Technology

[0002] Thermal management systems involve temperature control and energy efficiency optimization in multiple aspects of new energy vehicles, ensuring their performance, efficiency, and comfort under various conditions, and playing a crucial role in new energy vehicles.

[0003] The thermal management integrated module includes flow path components and several refrigerant valves. The refrigerant valves include multi-way refrigerant valves, which may include three-way valves, etc. The flow path components can be refrigerant flow path plates or valve islands. Each flow path component has multiple flow channels for refrigerant flow. The refrigerant valves connect to these flow path components, so that after these flow paths are connected to other modules in the thermal management integrated module, such as evaporators, condensers, or heat exchangers, multiple flow loops for refrigerant flow can be formed. This allows the refrigerant to flow in different flow loops, thus enabling the thermal management system to function.

[0004] Currently, the large number of refrigerant valves in thermal management integrated modules significantly increases their cost. To address this, multi-way refrigerant valves, often mechanical three-way valves, are frequently used in thermal management integrated modules to reduce the number of valves and lower the overall cost. However, the moving parts in these mechanical three-way valves are prone to jamming during movement within the valve body. Utility Model Content

[0005] This application provides a mechanical three-way valve, a thermal management integrated module, and a new energy vehicle. The mechanical three-way valve can solve the problem of easy jamming in existing mechanical three-way valves by reducing the cost of the thermal management integrated module.

[0006] In a first aspect, embodiments of this application provide a mechanical three-way valve, the mechanical three-way valve comprising:

[0007] The valve body has a valve cavity and multiple communication ports, which are used to connect the flow channels of the flow passage components at corresponding positions to the valve cavity; the multiple communication ports include a first communication port, a second communication port and a third communication port, wherein the second communication port is located between the first communication port and the third communication port;

[0008] A rotating component is rotatably positioned inside the valve cavity opposite to the second communication port, with the end of the rotating component facing the second communication port being the first sealing end;

[0009] When the refrigerant in the flow channel enters the valve cavity through one of the first and third connecting ports, the first sealing end is configured to rotate to a first position in the direction of the other of the first and third connecting ports under the push of the refrigerant, so that the first and third connecting ports are not connected, and the second connecting port is connected to the connecting port for injecting refrigerant into the valve cavity.

[0010] When the refrigerant in the flow channel enters the valve cavity through the second connecting port, the first sealing end is in the second position so that the first sealing end does not contact the cavity wall of the valve cavity, and both the first connecting port and the third connecting port are connected to the second connecting port.

[0011] This application embodiment utilizes a rotating component in a mechanical three-way valve. By rotating this component within the valve body and switching between a first and a second position, the flow path and flow rate of the refrigerant within the flow channel can be controlled. Compared to electrically controlled three-way valves, this mechanical three-way valve eliminates the electrically controlled components, reducing the cost of the three-way valve and the thermal management integration module. Since the rotating component controls the refrigerant flow path within the flow channel by rotating within the valve body, the problem of jamming during axial movement of the moving part is eliminated. This solves the problem of jamming in existing mechanical three-way valves, making the rotating component less prone to jamming while rotating within the valve body. Furthermore, it simplifies the structure of the mechanical three-way valve, reducing its axial dimension and consequently reducing the axial dimension of the flow channel, thus contributing to its lightweight design and the lightweight installation of the flow channel components.

[0012] Furthermore, when the rotating component rotates to the first position, it can increase the communication space between the first and third connecting ports and the second connecting port in the valve body, which is more conducive to the refrigerant flowing from the first and third connecting ports through the valve cavity to the second connecting port.

[0013] In addition, compared to the existing mechanical three-way valves where the moving parts are located on the outside of the valve body along the valve body axis, the rotating parts are located inside the valve cavity, so that the rotating parts are all located inside the valve body. Therefore, the mechanical three-way valve can be reduced in size in the axial direction, which in turn reduces the size of the flow passage parts in the mechanical three-way valve in the axial direction. This is beneficial for its own weight reduction and the weight reduction of its installed flow passage parts.

[0014] In some embodiments, the end of the rotating member facing away from the second communication port is the second sealing end, when the first sealing end is in the first position:

[0015] Both the first and second sealing ends abut against different positions on the valve cavity wall in the circumferential direction.

[0016] In some embodiments, along the axial direction of the valve body, the valve cavity includes a first valve cavity, a second valve cavity, and a third valve cavity, with the second valve cavity located between the first valve cavity and the third valve cavity; the first valve cavity has a first communication port on its cavity wall, the second valve cavity has a second communication port on its cavity wall, and the third valve cavity has a third communication port on its cavity wall;

[0017] The rotating component is rotatably disposed in the second valve cavity. Along the radial direction of the valve body, the end of the rotating component facing the second communication port is the first sealing end, and the end of the rotating component away from the second communication port is the second sealing end.

[0018] In some embodiments, along the axial direction of the valve body, the valve body includes a first valve section and a second valve section connected together.

The end of the first valve section facing the second valve section has a connecting portion with an opening that connects the first valve cavity and the second valve cavity. The inner wall of the second valve section has a first protrusion that divides the space within the second valve section into a second valve cavity and a third valve cavity. The first protrusion has a through-hole that connects the second valve cavity and the third valve cavity.

[0019] When the first sealing end is in the first position: the circumferential direction of the first sealing end abuts against the side of the connecting part facing the second valve section, and the circumferential direction of the second sealing end abuts against the side of the first protrusion facing the first valve section.

[0020] In some embodiments, the rotating member has a middle section located between the first sealing end and the second sealing end, and the middle section of the rotating member has a convex bulge in the circumferential direction;

[0021] When the rotating component is in the second position, the end face of the second sealing end abuts against the cavity wall of the second valve chamber, and the protrusion contacts the connecting part and the first protrusion.

[0022] In some embodiments, the rotating member has a middle section located between the first sealing end and the second sealing end, and the rotating member has a smooth circumferential outer wall in the middle section;

[0023] When the rotating component is in the second position, the end face of the second sealing end abuts against the cavity wall of the second valve chamber, and the circumferential outer wall does not contact the connecting part and the first protrusion.

[0024] In some embodiments, the mechanical three-way valve further includes a first sealing element, and the first sealing element is sleeved on both the first sealing end and the second sealing end in the circumferential direction;

[0025] When the first sealing end is in the first position: both the first sealing end and the second sealing end abut against the cavity wall of the valve cavity through the first sealing element.

[0026] In some embodiments, when the first blocking end is in the second position, the center of the first blocking end is located on the center line of the second communication port.

[0027] In some embodiments, the mechanical three-way valve further includes a rotating shaft disposed in the valve cavity, and the rotating component has a sleeve portion located on the side of the first sealing end away from the second communication port.

[0028] The rotating shaft passes through the sleeve portion, and the rotating component is configured to rotate around the rotating shaft.

[0029] In some embodiments, the device further includes an elastic element located between the sleeve portion and the rotating shaft, with one end of the elastic element connected to the sleeve portion and the other end of the elastic element connected to the rotating shaft.

[0030] The elastic element is configured to deform as the first sealing end rotates to the first position, so that when the refrigerant does not enter the valve cavity through the first and third connecting ports, the elastic element drives the first sealing end to rotate in the opposite direction to the second position.

[0031] In some embodiments, the elastic element includes a torsion spring, which is sleeved on the circumferential outer wall of the shaft.

[0032] Secondly, embodiments of this application provide a thermal management integrated module, which includes a flow element and a mechanical three-way valve as described above. At least a portion of the mechanical three-way valve is installed within the flow element, and the flow element has a flow channel at each connection port corresponding to the mechanical three-way valve, with the connection port communicating with the corresponding flow channel.

[0033] In some embodiments, the thermal management system further includes an elastic fastener having two free ends; at least a portion of the valve body of the mechanical three-way valve is mounted within the flow passage, the valve body having a shoulder protruding outwards from the valve body, and the flow passage having a support portion at a position corresponding to the shoulder, the support portion being supported at the bottom of the shoulder;

[0034] The flow channel component also has a fixing groove on the side of the shoulder away from the support. The elastic fastener is configured to be disposed in the fixing groove and pressed against the side of the shoulder away from the support when the two free ends deform in a direction that brings them closer together.

[0035] In some embodiments, when the support is supported on the bottom of the shoulder, the side of the shoulder facing away from the support is flush with the groove wall of the fixing groove near the shoulder.

[0036] In some embodiments, the valve body and flow passage of the mechanical three-way valve are provided with alignment marks, and when at least a portion of the valve body is installed in the flow passage, the alignment marks on the valve body and the flow passage are aligned with each other.

[0061] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0062] This application provides an embodiment of a new energy vehicle. For example, a new energy vehicle may include electric vehicles and hybrid electric vehicles. A hybrid electric vehicle can refer to a new energy vehicle that combines an internal combustion engine and an electric motor as power systems.

[0063] New energy vehicles include thermal management systems. The thermal management system plays a crucial role in new energy vehicles. It involves temperature control and energy efficiency optimization in multiple aspects, ensuring the performance, efficiency, and comfort of new energy vehicles under various conditions.

[0064] The thermal management system includes an integrated thermal management module. In electric new energy vehicles, the inclusion of this module significantly reduces the number of pipes required for the thermal management system and lowers its failure rate.

[0065] The thermal management integrated module includes flow path components and multiple refrigerant valves. Refrigerant valves include conventional refrigerant valves and multi-way refrigerant valves. For example, conventional refrigerant valves include solenoid-operated valves (SOV), electronic expansion valves (EXV), or check valves (CV). Multi-way refrigerant valves may include three-way valves. Flow path components can be refrigerant flow channels, also known as valve islands. As described in the background section, to reduce the number of refrigerant valves in the thermal management integrated module, multi-way refrigerant valves are commonly used in related technologies. These multi-way refrigerant valves can be mechanical three-way valves, thus reducing the cost of the thermal management integrated module.

[0066] However, the currently used mechanical three-way valve includes a valve body and a moving component. The valve body has multiple communication ports along its axial direction that connect with the flow channels of the flow passage components. The moving component is located within the valve body. When the moving component moves along the axial direction of the valve body within the valve body, it can control the flow path of the refrigerant within the flow passage components.

[0067] Currently, in these types of mechanical three-way valves, the moving component is prone to jamming during its movement within the valve body. This is because the movement of the moving component in these valves is driven by the pressure difference between the refrigerant entering the valve body's connecting port and other ports. For example, when the refrigerant enters the valve body from the connecting port at one axial end, the pressure at that port is higher, driving the moving component towards the connecting port at the other end of the valve body to connect the two flow channels within the mechanical three-way valve. Furthermore, because the moving component's circumferential and internal parts of the valve body are both interference-fitted, and the interference is substantial, this interference can hinder the moving component from moving in the reverse direction after it has reached its position within the valve body. This makes the moving component highly susceptible to jamming when it moves axially backward within the valve body.

[0068] In addition, since some moving parts are located outside the valve body along the axial direction, this results in a large axial dimension for this type of mechanical three-way valve, which is not conducive to its own weight reduction and the weight reduction of its installed flow passage components.

[0069] Therefore, this application provides a mechanical three-way valve, and the thermal management integration module includes the mechanical three-way valve of this application embodiment. The mechanical three-way valve includes a valve body and a rotating component. By rotating the rotating component within the valve body, the flow path of the refrigerant within the flow channel can be controlled. Compared to electrically controlled three-way valves, the mechanical three-way valve of this application can reduce the cost of the thermal management integration module. Furthermore, compared to existing mechanical three-way valves where the moving component moves axially within the valve body, the rotational arrangement of the rotating component within the valve body solves the problem of easy jamming in existing mechanical three-way valves. It also simplifies the structure of the mechanical three-way valve, reduces its axial dimensions, and contributes to its own weight reduction and the weight reduction of its installed flow channel components.

[0070] The structure of the mechanical three-way valve of this application will be further described below with reference to the accompanying drawings.

[0071] See Figure 1 and Figure 2 This application provides a mechanical three-way valve 100, which includes a valve body 1. The valve body 1 has a valve cavity 11 and a plurality of connecting ports 12, which are used to connect the flow channels 210 of the flow channel component 200 at corresponding positions to the valve cavity 11. The plurality of connecting ports 12 include a first connecting port 121, a second connecting port 122, and a third connecting port 123. The second connecting port 122 is located between the first connecting port 121 and the third connecting port 123.

[0072] See Figure 1 At least a portion of the mechanical three-way valve 100 is installed in the flow channel component 200. The flow channel component 200 is provided with a flow channel 210 at each position corresponding to the connection port 12 of the mechanical three-way valve 100. The connection port 12 is connected to the corresponding flow channel 210 so that the connection port 12 connects the flow channel 210 of the flow channel component 200 at the corresponding position to the valve cavity 11.

[0073] Specifically, the flow channel component 200 is provided with flow channels 210 at positions corresponding to the first connecting port 121, the second connecting port 122, and the third connecting port 123. For ease of description, the flow channel 210 in the flow channel component 200 corresponding to the first connecting port 121 is referred to as the first flow channel 211, the flow channel 210 in the flow channel component 200 corresponding to the second connecting port 122 is referred to as the second flow channel 212, and the flow channel 210 in the flow channel component 200 corresponding to the third connecting port 123 is referred to as the third flow channel 213. The first connecting port 121 is used to connect the first flow channel 211 to the valve cavity 11, the second connecting port 122 is used to connect the second flow channel 212 to the valve cavity 11, and the third connecting port 123 is used to connect the third flow channel 213 to the valve cavity 11.

[0074] See Figure 1 and Figure 2The mechanical three-way valve 100 also includes a rotating component 2, which is rotatably disposed within the valve cavity 11 at a position opposite to the second communication port 122. The end of the rotating component 2 facing the second communication port 122 is the first sealing end 21.

[0075] See Figure 3 and Figure 4 When the refrigerant in the flow channel 210 enters the valve chamber 11 through one of the first connecting port 121 and the third connecting port 123, the first sealing end 21 is configured to rotate to a first position under the push of the refrigerant toward the other of the first connecting port 121 and the third connecting port 123, so that the first connecting port 121 and the third connecting port 123 are not connected, and the second connecting port 122 is connected to the connecting port 12 for injecting refrigerant into the valve chamber 11.

[0076] For example, such as Figure 3 As shown, when the refrigerant in the first flow channel 211 enters the valve chamber 11 through the first connecting port 121, the first sealing end 21 is configured to rotate to the first position towards the third connecting port 123 under the push of the refrigerant. For example, as... Figure 4 As shown, when the refrigerant in the third flow channel 213 enters the valve chamber 11 through the third connecting port 123, the first sealing end 21 is configured to rotate to the first position in the direction of the first connecting port 121 under the push of the refrigerant.

[0077] By limiting the connection status of the first connecting port 121, the second connecting port 122, and the third connecting port 123 when the first sealing end 21 is in the first position, only one of the first connecting port 121 and the third connecting port 123 is connected to the second connecting port 122, making the second connecting port 122 the sole outlet for the refrigerant. After the refrigerant in the flow channel component 200 enters the valve chamber 11 through the first connecting port 121 or the third connecting port 123, it can only flow out through the second connecting port 122 and re-enter the flow channel 210 (second flow channel 212) in the flow channel component 200 opposite to the second connecting port 122.

[0078] See Figure 5 When the refrigerant in the flow channel 210 enters the valve chamber 11 through the second connecting port 122, the first sealing end 21 is in the second position so that the first sealing end 21 does not contact the cavity wall of the valve chamber 11, and both the first connecting port 121 and the third connecting port 123 are connected to the second connecting port 122. With this configuration, both the first connecting port 121 and the third connecting port 123 can serve as refrigerant outlets. After the refrigerant in the flow channel component 200 enters the valve chamber 11 through the second connecting port 122, it can simultaneously flow out through the first connecting port 121 and the third connecting port 123, and re-enter the flow channels 210 (first flow channel 211 and third flow channel 213) in the flow channel component 200 corresponding to the first connecting port 121 and the third connecting port 123.

[0079] Therefore, the embodiments of this application can control the flow path and flow rate of the refrigerant in the flow channel component 200 by rotating the rotating component 2 within the valve body 1 and switching between the first and second positions, thereby reducing the cost of the three-way valve and the thermal management integrated module.

[0080] Furthermore, since the rotating component 2 changes the flow path of the refrigerant in the flow channel component 200 by rotating within the valve body 1, the problem of the aforementioned moving component easily getting stuck when moving axially within the valve body 1 is not present, thus solving the problem of the existing mechanical three-way valve 100 being prone to getting stuck.

[0081] Compared to the existing mechanical three-way valve 100 where the moving part is located outside the valve body 1 along the axial direction of the valve body 1, since the rotating member 2 is rotatably located inside the valve cavity 11, the rotating member 2 is located inside the valve body 1. Therefore, the axial dimension of the mechanical three-way valve 100 can be reduced, thereby reducing the axial dimension of the flow channel member 200, which is beneficial to its own weight reduction and the weight reduction of its installed flow channel member 200.

[0082] In addition, when the rotating component 2 rotates to the first position, it can increase the communication space between one of the first communication port 121 and the third communication port 123 and the second communication port 122 in the valve body 1, which is more conducive to the refrigerant flowing from one of the first communication port 121 and the third communication port 123 through the valve cavity 11 to the second communication port 122.

[0083] See Figure 3 and Figure 4 In some embodiments, the end of the rotating member 2 that is away from the second communication port 122 is the second blocking end 22. When the first blocking end 21 is in the first position:

[0084] The first sealing end 21 and the second sealing end 22 both abut against different positions of the valve cavity 11 on the cavity wall in the circumferential direction.

[0085] By having the first sealing end 21 and the second sealing end 22 circumferentially abut against different positions on the cavity wall, it can be ensured that the connecting port 12 for injecting refrigerant into the valve cavity 11 is connected to the second connecting port 122, and the first connecting port 121 and the third connecting port 123 are not connected, so that the second connecting port 122 serves as the only outlet for refrigerant.

[0086] See Figures 3 to 5In some embodiments, along the axial direction of the valve body 1, the valve cavity 11 includes a first valve cavity 111, a second valve cavity 112, and a third valve cavity 113, with the second valve cavity 112 located between the first valve cavity 111 and the third valve cavity 113. The first valve cavity 111 has a first connecting port 121 on its cavity wall, the second valve cavity 112 has a second connecting port 122 on its cavity wall, and the third valve cavity 113 has a third connecting port 123 on its cavity wall, such that the second connecting port 122 is located between the first connecting port 121 and the third connecting port 123 along the axial direction of the valve body 1.

[0087] The rotating member 2 is rotatably disposed within the second valve chamber 112. Along the radial direction of the valve body 1, the end of the rotating member 2 facing the second communication port 122 is the first sealing end 21, and the end of the rotating member 2 away from the second communication port 122 is the second sealing end 22. This arrangement allows the rotating member 2 to rotate radially within the valve body 1 to a position opposite to the second communication port 122. Simultaneously, it facilitates the rotation of the rotating member 2 within the second valve chamber 112, and allows control of the refrigerant flow path within the flow channel component 200 when switching between the first and second positions.

[0088] See Figure 3 In some embodiments, the valve body 1 may include a first valve section 13 and a second valve section 14 connected in the axial direction. The first valve section 13 and the second valve section 14 are two independent components that can be connected by welding, snap-fitting, threaded connection, or fasteners. For example, fasteners may include screws, bolts, etc. The first valve section 13 has a first valve cavity 111, and a first connecting port 121 penetrates the cavity wall of the first valve section 13 to communicate with the first valve cavity 111. The second valve section 14 has a second valve cavity 112 and a third valve cavity 113. The second connecting port 122 penetrates the cavity wall of the second valve section 14 at a position opposite to the second valve cavity 112 to communicate with the second valve cavity 112. The third connecting port 123 penetrates the cavity wall of the second valve section 14 at a position opposite to the third valve cavity 113 to communicate with the third valve cavity 113.

[0089] Compared to the valve body 1 being integrally molded, the design of the first valve section 13 and the second valve section 14 as two components reduces the processing difficulty of the valve body 1 and facilitates its manufacture.

[0090] The following section takes the valve body 1, which includes the first valve section 13 and the second valve section 14, as an example to further illustrate the structure of the mechanical three-way valve 100.

[0091] See Figure 1 and Figure 3One end of the valve body 1 with the third communication port 123 can be inserted into the flow channel component 200 to realize the installation of the valve body 1 and the mechanical three-way valve 100 in the flow channel component 200.

[0092] See Figure 1 and Figure 3 In some embodiments, the radial dimension of the valve body 1 can gradually decrease along its axial direction, with the radial dimension of the valve body 1 near the third communication port 123 being smaller than the radial dimension of the valve body 1 near the first communication port 121. Specifically, the radial dimension of the valve body 1 can gradually decrease along the direction from the first valve segment 13 to the second valve segment 14, so that the radial dimension of the valve body 1 near the third communication port 123 is smaller than the radial dimension of the valve body 1 near the first communication port 121. By limiting the radial dimension of the valve body 1 along its axial direction as described above, the valve body 1 can be easily inserted into the flow channel component 200.

[0093] See Figure 3 The first valve section 13 has a connecting portion 131 at one end facing the second valve section 14. The connecting portion 131 has an opening 15. The opening 15 connects the first valve chamber 111 and the second valve chamber 112. The connecting portion 131 is connected to the second valve section 14. When the connecting portion 131 is connected to the second valve section 14, the connecting portion 131 can at least partially be located on the side of the second valve chamber 112 facing the first valve chamber 111, forming a protrusion on the cavity wall of the valve chamber 11.

[0094] See Figure 3 The inner wall of the second valve section 14 has a first protrusion 142, which divides the space within the second valve section 14 into a second valve chamber 112 and a third valve chamber 113. The first protrusion 142 has a through-hole 141, which connects the second valve chamber 112 and the third valve chamber 113. The first protrusion 142 constitutes another protrusion on the wall of the valve chamber 11.

[0095] See Figure 3 and Figure 4 In some embodiments, the end of the rotating member 2 that is away from the second communication port 122 is the second blocking end 22. When the first blocking end 21 is in the first position:

[0096] The circumferential direction of the first sealing end 21 can abut against the side of the connecting part 131 facing the second valve section 14, and the circumferential direction of the second sealing end 22 can abut against the side of the first protrusion 142 facing the first valve section 13, so that the circumferential directions of the first sealing end 21 and the second sealing end 22 both abut against different positions of the valve cavity 11 on the cavity wall.

[0097] By having the first sealing end 21 and the second sealing end 22 circumferentially abut against different positions on the cavity wall, it can be ensured that the connecting port 12 for injecting refrigerant into the valve cavity 11 is connected to the second connecting port 122, and the first connecting port 121 and the third connecting port 123 are not connected, so that the second connecting port 122 serves as the only outlet for refrigerant.

[0098] See Figure 3 and Figure 4 In some embodiments, a first sealing element 3 is fitted around both the first sealing end 21 and the second sealing end 22. For example, the first sealing element 3 can be a sealing ring, etc. When the first sealing end 21 is in the first position: both the first sealing end 21 and the second sealing end 22 abut against the cavity wall of the valve cavity 11 through the first sealing element 3, so that the first sealing end 21 and the second sealing end 22 can be sealed and connected to the cavity wall of the valve cavity 11 through the first sealing element 3. This ensures that one of the first connecting port 121 and the third connecting port 123 is connected to the second connecting port 122, while better preventing the other of the first connecting port 121 and the third connecting port 123 from connecting to the second connecting port 122, thus achieving better sealing performance.

[0099] Furthermore, since the first sealing element 3 is disposed circumferentially on both the first sealing end 21 and the second sealing end 22, and the rotating member 2 is rotatably disposed within the valve cavity 11, when the rotating member 2 rotates, causing the first sealing end 21 to rotate to the first position, the outer wall of the first sealing element 3 on the first sealing end 21 will adhere to the cavity wall of the valve cavity 11. When the first sealing end 21 rotates to the first position, the second sealing end 22 also rotates synchronously, and the outer wall of the first sealing element 3 on the second sealing end 22 will adhere to the cavity wall of the valve cavity 11. This arrangement enables a sealed connection between the first sealing end 21 and the second sealing end 22 and the cavity wall of the valve cavity 11.

[0100] When the rotating component 2 switches from the first position to the second position, the first sealing end 21 rotates toward the direction of the second connecting port 122, and the second sealing end 22 also rotates synchronously. In this way, the first sealing element 3 can be separated from the cavity wall of the valve cavity 11, and the sealing connection between the first sealing end 21 and the second sealing end 22 and the cavity wall of the valve cavity 11 is released.

[0101] Therefore, compared with the existing mechanical three-way valve 100, the first sealing element 3, which is set to achieve the sealing connection between the first sealing end 21 and the second sealing end 22 and the cavity wall of the valve cavity 11, will not affect the switching of the rotating component 2 between the first position and the second position. While achieving the smooth switching of the first sealing end 21 between the first position and the second position, there is no problem that the rotating component 2 is prone to jamming when rotating.

[0102] See Figures 2 to 5In some embodiments, when the first sealing end 21 is in the second position, its center is located on the centerline of the second connecting port 122. This arrangement helps ensure that, in the second position, the radial distance between the first sealing end 21 and the inner wall of the second connecting port 122 is equal, placing the first sealing end 21 in the middle of the second connecting port 122. This ensures that when the refrigerant in the flow channel 200 and the corresponding flow channel 210 (e.g., the second flow channel 212) enters the valve chamber 11 from the second connecting port 122, the radial thrust on opposite sides of the first sealing end 21 is substantially equal, preventing the first sealing end 21 from rotating. Thus, the position of the first sealing end 21 in the second position (…) Figure 5 As shown, this can be considered as the initial position of the first blocking end 21. Figure 2 As shown), the first sealing end 21 only needs to be in Figure 2 By rotating approximately the same angle in two opposite directions from the initial position, one can reach... Figure 3 and Figure 4 The two first positions shown in the figure can simplify the switching of the rotating member 2 between the second position and the two first positions.

[0103] The following is combined with Figures 3 to 5 The three connection states of the mechanical three-way valve 100 of this application are further described.

[0104] See Figure 3 The first connecting port 121 and the second connecting port 122 are connected. When the refrigerant enters the valve chamber 11 through the first connecting port 121, the first connecting port 121 is at a relatively high pressure end relative to the third connecting port 123. The relatively high pressure of the refrigerant exerts a thrust on the first sealing end 21 of the rotating member 2, causing the first sealing end 21 to rotate toward the position of the third connecting port 123 to the first position. As the refrigerant continues to flow in from the first connecting port 121, the refrigerant will continue to exert a thrust on the first sealing end 21, ensuring that the third connecting port 123 is always in a closed state and does not connect with the first connecting port 121 and the second connecting port 122. At this time, the second connecting port 122 serves as the only outlet for the refrigerant on the valve body 1. When the rotating member 2 rotates to the first position, the communication space between the first connecting port 121 and the second connecting port 122 within the valve body 1 increases, which is more conducive to the flow of the refrigerant.

[0105] See Figure 4The third connecting port 123 is connected to the second connecting port 122. When the refrigerant enters the valve chamber 11 through the third connecting port 123, the third connecting port 123 is at a relatively high pressure end relative to the first connecting port 121. The relatively high pressure refrigerant exerts a thrust on the first sealing end 21 of the rotating member 2, causing the first sealing end 21 to rotate toward the position of the first connecting port 121 to another first position. As the refrigerant continues to flow in from the third connecting port 123, the refrigerant will continue to exert a thrust on the first sealing end 21, ensuring that the first connecting port 121 is always in a closed state and is not connected to the second connecting port 122 and the third connecting port 123. At this time, the second connecting port 122 still serves as the only outlet for the refrigerant on the valve body 1. When the rotating member 2 rotates to this first position, the communication space between the third connecting port 123 and the second connecting port 122 in the valve body 1 increases, which is more conducive to the flow of refrigerant.

[0106] See Figure 5 Both the first connecting port 121 and the third connecting port 123 are connected to the second connecting port 122. When the refrigerant enters the valve chamber 11 through the third connecting port 123, the second connecting port 122 is at a relatively high pressure end relative to the first connecting port 121 and the third connecting port 123. Because the first sealing end 21 is located in the middle of the second connecting port 122, the refrigerant flowing out of the second connecting port 122 exerts a basically equal radial thrust on the first sealing end 21 of the rotating member 2 on both sides, and the first sealing end 21 does not rotate. At this time, the second connecting port 122 serves as the only inlet for the refrigerant on the valve body 1, and the first connecting port 121 and the third connecting port 123 serve as the outlets for the refrigerant on the valve body 1.

[0107] See Figure 6 and Figure 7 In some embodiments, the mechanical three-way valve 100 further includes a rotating shaft 4 disposed within the valve chamber 11. The rotating member 2 has a sleeve portion 24 located on the side of the first sealing end 21 opposite to the second communication port 122. The rotating shaft 4 passes through the sleeve portion 24, and the rotating member 2 is configured to rotate about the rotating shaft 4. With this configuration, the rotating member 2 will rotate about the rotating shaft 4 within the valve chamber 11 (second valve chamber 112) under the push of the refrigerant, realizing the switching of the rotating member 2 between a first position and a second position.

[0108] The rotating shaft 4 can be installed in the valve cavity 11 by means of plugging, snapping, or welding. Specifically, the rotating shaft 4 can be installed in the second valve cavity 112.

[0109] See Figure 7In some embodiments, the rotating member 2 has an intermediate section 23 located between the first sealing end 21 and the second sealing end 22. The intermediate section 23 of the rotating member 2 has a circumferential protrusion 231. When the rotating member 2 is in the second position, the end face of the second sealing end 22 can abut against the cavity wall of the second valve chamber 112, and the protrusion 231 can also contact the connecting part 131 and the first protrusion 142 to ensure that after the refrigerant enters the second valve chamber 112 through the second connecting port 122, it can flow directly toward the positions where the first connecting port 121 and the third connecting port 123 are located, ensuring that the refrigerant can quickly flow out of the valve chamber 11 from the first connecting port 121 and the third connecting port 123.

[0110] See Figure 8 Therefore, in some embodiments, the rotating member 2 has a smooth circumferential outer wall in the intermediate section 23, that is, the rotating member 2 does not have a protrusion 231 in the circumferential direction of the intermediate section 23, and is relatively flat. When the rotating member 2 is in the second position, the end face of the second sealing end 22 can abut against the cavity wall of the second valve cavity 112, and the circumferential outer wall of the rotating member 2 in the intermediate section 23 does not contact the connecting part 131 and the first protrusion 142. At this time, the circumferential outer wall of the intermediate section 23 and the second sealing end 22 will not form a relatively sealed cavity with the cavity wall of the second valve cavity 112. In this way, after the refrigerant enters the second valve chamber 112 through the second connecting port 122, some of the refrigerant will flow towards the second sealing end 22 and then flow out of the valve chamber 112 from the first connecting port 121 and the third connecting port 123. This avoids the formation of a bulge 231 and the second sealing end 22 forming a relatively sealed cavity with the cavity wall of the second valve chamber 112, thus ensuring that the rotating component 2 can rotate quickly under the push of the refrigerant.

[0111] See Figure 7 , Figure 9 and Figure 10 In some embodiments, the mechanical three-way valve 100 further includes an elastic element 5 located between the sleeve portion 24 and the rotating shaft 4, with one end of the elastic element 5 connected to the sleeve portion 24 and the other end connected to the rotating shaft 4. The elastic element 5 is configured to deform during the rotation of the first sealing end 21 to the first position, so that when the refrigerant does not enter the valve cavity 11 through the first connecting port 121 and the third connecting port 123, the elastic element 5 drives the first sealing end 21 to rotate in the opposite direction to the second position. This configuration allows the rotating member 2 to automatically reset to the second position within the valve cavity 11 via the elastic element 5, so that both the first connecting port 121 and the third connecting port 123 are connected to the second connecting port 122.

[0112] Furthermore, since the elastic element 5 is located between the sleeve portion 24 and the rotating shaft 4, the elastic element 5 is hidden inside the rotating member 2. This does not occupy the space for refrigerant flow in the valve cavity 11, which can reduce the flow resistance of the refrigerant when it flows in the valve cavity 11 and improve the performance of the mechanical three-way valve 100. At the same time, it can also make all the components of the mechanical three-way valve 100 except the valve body 1 located inside the valve body 1, with no exposed parts. This can make the mechanical three-way valve 100 smaller in axial direction, lighter in overall weight, and lower in cost.

[0113] For example, the elastic element 5 may include a torsion spring, which is sleeved on the circumferential outer wall of the rotating shaft 4. In this way, the two ends of the torsion spring are connected to the sleeve portion 24 and the rotating shaft 4 respectively, and the torsion spring will deform during the process of the rotating member 2 rotating around the rotating shaft 4 to the first position.

[0114] See Figure 6 As an example, a first groove 241 may be provided on the inner wall of the sleeve portion 24, and a second groove 41 may be provided on the circumferential outer wall of the rotating shaft 4. One end of the elastic element 5 may be installed and fixed in the first groove 241, and the other end of the elastic element 5 may be installed and fixed in the second groove 41, so as to realize the connection between the elastic element 5 and the sleeve portion 24 and the rotating shaft 4.

[0115] It should be noted that when the refrigerant does not enter the valve chamber 11 through the first connecting port 121 and the third connecting port 123, the elastic element 5 can provide some force to the rotating member 2, which can help the rotating member 2 maintain the second position (initial position) in the valve chamber 11.

[0116] This solution utilizes the pressure difference between the refrigerants in different parts of the thermal management system, and combines it with a suitable elastic element 5 to enable the refrigerant to flow from different connection ports 12 into the valve body 1. The refrigerant drives the rotating component 2 to rotate automatically, thereby achieving automatic control of the refrigerant flow direction and flow rate in the circulation loop.

[0117] The installation of the mechanical three-way valve 100 within the flow channel component 200 will be further described below with reference to the accompanying drawings.

[0118] See Figure 1 and Figure 11 In some embodiments, the thermal management system further includes a resilient fastener 6 having two free ends 61. The two free ends 61 are configured to move toward each other under the action of an external force to adjust the radial dimension of the resilient fastener 6. For example, when the two free ends 61 move toward each other under the action of an external force, the radial dimension of the resilient fastener 6 can be reduced.

[0119] The valve body 1 has a shoulder 16 protruding outwards. When at least a portion of the valve body 1 is installed within the flow channel member 200, the flow channel member 200 has a support portion 220 at a position corresponding to the shoulder 16, the support portion 220 supporting the bottom of the shoulder 16. The flow channel member 200 also has a fixing groove 230 on the side of the shoulder 16 away from the support portion 220. The elastic fixing member 6 is configured to be disposed within the fixing groove 230 and pressed against the side of the shoulder 16 away from the support portion 220 when the two free ends 61 deform in a direction toward each other. Specifically, when the external force applied to the two free ends 61 disappears, the two free ends 61 will move in a direction away from each other, restoring the original radial dimension of the elastic fixing member 6, so that the elastic fixing member 6 is pressed against the side of the shoulder 16 away from the support portion 220.

[0120] Through the combined action of the support 220 and the elastic fastener 6, the valve body 1 can be fixed inside the flow channel 200, so as to realize the installation of the mechanical three-way valve 100 inside the flow channel 200.

[0121] Furthermore, compared to the valve body 1 being connected to the flow channel component 200 via threads, the mechanical three-way valve 100 can be more easily installed in the flow channel component 200 via the elastic fastener 6 and the support part 220, resulting in higher assembly and maintenance efficiency of the mechanical three-way valve 100 in the flow channel component 200.

[0122] See Figure 1 In some embodiments, when the support portion 220 is supported on the bottom of the shoulder portion 16, the side of the shoulder portion 16 away from the support portion 220 is flush with the groove wall of the fixing groove 230 near the shoulder portion 16, so as to ensure that the elastic fastener 6 can be pressed well on the side of the shoulder portion 16 away from the support portion 220.

[0123] See Figure 1 In some embodiments, the valve body 1 of the new energy vehicle has a second seal 7 in the circumferential direction. When at least a portion of the valve body 1 is installed within the flow channel 200, the second seal 7 is disposed between the valve body 1 and the flow channel 200. The second seal 7 enables a seal between the valve body 1 and the flow channel 200.

[0124] There can be multiple second seals 7. Multiple second seals 7 can be spaced apart along the axial direction of the valve body 1 on the circumferential outer wall of the valve body 1 to achieve sealing between the valve body 1 and the flow channel component 200 at multiple locations.

[0125] Figure 1Three second seals 7 are shown, designated as second seal 7a, second seal 7b, and second seal 7c. Second seal 7a is located at the end of the valve body 1 adjacent to the exterior of the flow channel 200. For example, second seal 7a may be located at the end of the first valve section 13 away from the second valve section 14. Second seal 7a prevents refrigerant leakage to the exterior of the flow channel 200. Second seals 7b and 7c are located at the end of the valve body 1 facing the interior of the flow channel 200. For example, second seal 7b may be located in the first valve section 13 near the second valve section 14, and second seal 7c may be located on the second valve section 14. Second seal 7b prevents refrigerant leakage between adjacent flow channels 210 within the flow channel 200.

[0126] In some embodiments, both the valve body 1 and the flow channel component 200 are provided with alignment marks. When at least a portion of the valve body 1 is installed within the flow channel component 200, and the connecting port 12 on the valve body 1 corresponds to the corresponding flow channel 210, the alignment marks on the valve body 1 and the flow channel component 200 are aligned with each other. With this configuration, by observing the alignment marks on the valve body 1 and the flow channel component 200, it can be determined whether the connecting port 12 on the valve body 1 corresponds to the corresponding flow channel 210, ensuring that the connecting port 12 and the corresponding flow channel 210 do not have excessive positional misalignment, allowing the refrigerant to flow more smoothly between the connecting port 12 and the corresponding flow channel 210, resulting in lower refrigerant flow resistance.

[0127] Alignment markings can be, but are not limited to, straight lines. In this case, the alignment markings on the valve body 1 and the flow channel component 200 are aligned with each other, which can be understood as the straight lines serving as alignment markings on the valve body 1 and the flow channel component 200 being on the same straight line.

[0128] It should be noted that alignment marks can also be patterns that can be aligned with each other, etc. This will not be elaborated upon further here.
