[0001] The present application relates to the technical field of switching valves, and in particular to a multi-way valve, an integrated module, a thermal management system and a vehicle. Background Art

[0002] In the prior art, in order for the thermal management system to meet the heating or cooling requirements of the vehicle for the motor, battery or passenger compartment, it is usually necessary to design a complex circuit and use multiple valves to adjust the connection relationship between the circuits according to the requirements of the thermal management system. However, due to the large number of valves, the thermal management system occupies a large space and has a low degree of integration, which increases costs and control difficulties. Summary of the invention

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the first purpose of the present application is to propose a multi-way valve, which has a high degree of integrated design, a simple structure and a compact size, so as to reduce the cost of the integrated module and the thermal management system, and solve the technical problems in the prior art that multiple valves are required, resulting in a large space occupied by the thermal management system, a low degree of integration, a high cost and a high control difficulty.

[0004] The second objective of the present application is to provide an integrated module having the multi-way valve.

[0005] The third objective of the present application is to provide a thermal management system having the above-mentioned multi-way valve.

[0006] A fourth objective of the present application is to provide a vehicle having the above-mentioned integrated module or thermal management system.

[0007] In a first aspect, an embodiment of the present application provides a multi-way valve, comprising: a valve body, the valve body being provided with at least five valve ports; a valve core, the valve core being rotatably disposed in the valve body, the valve core comprising a first flow channel and a second flow channel arranged at intervals, the first flow channel being used to communicate with the two valve ports, the valve core being rotated so that the first flow channel is used to communicate with different valve ports; the second flow channel having a switching mode and a proportional adjustment mode, the valve core being rotated so that the second flow channel is switched between the switching mode and the proportional adjustment mode, in the switching mode, the second flow channel being used to communicate with the two valve ports and to communicate with different valve ports when the valve core is rotated, and in the proportional adjustment mode, the second flow channel being used to communicate with at least three valve ports and to change the connection area with at least one valve port when the valve core is rotated.

[0008] In the technical solution of the embodiment of the present application, by setting the first flow channel and the second flow channel arranged at intervals, and setting the second flow channel to have a switching mode and a proportional adjustment mode, the multi-way valve of the present application can be simplified in structure while having a switching function and a proportional adjustment function at the same time, so that a multi-way valve can replace a three-way valve and a four-way valve at the same time, thereby improving the integration of the multi-way valve and expanding the adaptability of the multi-way valve. In this way, the multi-way valve is applied to the thermal management system and the integrated module, which can effectively improve the integration of the thermal management system and the integrated module and reduce the control difficulty and cost of the thermal management system and the integrated module.

[0009] In some embodiments, the at least five valve ports include a central valve port and a plurality of peripheral valve ports, the peripheral valve ports are arranged at intervals around the central valve port, the first flow channel is connected to the central valve port, the valve core rotates so that the first flow channel is connected to different peripheral valve ports, and the second flow channel is used to connect at least two peripheral valve ports to switch between the switching mode and the proportional adjustment mode. Thus, the multi-way valve of the present application has both the switching function and the proportional adjustment function, so as to realize the use of a multi-way valve to replace a three-way valve and a four-way valve at the same time, improve the integration of the multi-way valve, and ensure the function of the multi-way valve.

[0010] In some embodiments, the valve core is provided with an annular blocking protrusion, which stops at the valve body and is arranged around the central valve opening. While preventing the blocking protrusion from blocking the central valve opening, the blocking protrusion can also be used to reduce the contact area between the valve core and the valve body, thereby reducing the friction between the valve core and the valve body, ensuring that the valve core can effectively rotate relative to the valve body and reducing the difficulty of rotation.

[0011] In some embodiments, the plurality of peripheral valve ports include a first valve port, a second valve port, a third valve port and a fourth valve port, the first valve port and the second valve port are symmetrically arranged relative to the central valve port, and the third valve port and the fourth valve port are symmetrically arranged relative to the central valve port. This reduces the difficulty of forming the plurality of peripheral valve ports, and ensures that when the valve core rotates, the first flow channel can communicate with the central valve port and one of the peripheral valve ports, and enables the second flow channel to communicate with at least two peripheral valve ports, so as to facilitate the switching function and proportional adjustment function of the multi-way valve and improve the integration of the multi-way valve.

[0012] In some embodiments, the second flow channel is formed as an arc-shaped flow channel, so that when the external medium flows along the second flow channel, the resistance of the second flow channel to the external medium can be reduced, thereby reducing the pressure drop and flow loss of the external medium, and ensuring the performance of the multi-way valve.

[0013] In some embodiments, the central angle of the second flow channel is not less than 180°, so as to ensure that when the valve core rotates, the second flow channel can communicate with at least two peripheral valve ports, thereby ensuring the performance of the multi-way valve and facilitating the switching function and proportional adjustment function of the multi-way valve.

[0014] In some embodiments, the first flow channel includes a first part and a second part, the first end of the first part is connected to the central valve port, the second end of the first part is connected to the second part, the second part is formed into an arc-shaped flow channel, and the second part is used to communicate with different peripheral valve ports, thereby achieving communication between the central valve port and different peripheral valve ports, so as to ensure the function of the multi-way valve and facilitate switching between multiple modes.

[0015] In some embodiments, the valve core rotates so that the first flow channel can be connected to any one of the plurality of peripheral valve ports. In other words, the first flow channel can connect the central valve port to any peripheral valve port, so that the multi-way valve can have multiple working modes and can switch between multiple working modes without increasing the cost of the multi-way valve, greatly expanding the adaptability of the multi-way valve.

[0016] In some embodiments, the valve core rotates so that the second flow channel can be connected to any two adjacent ones or any three adjacent ones of the plurality of peripheral valve ports. That is to say, the second flow channel can connect any two adjacent peripheral valve ports, or any three adjacent peripheral valve ports, wherein when any two adjacent peripheral valve ports are connected, it can be used to achieve function switching, and when any three adjacent peripheral valve ports are connected, it can be used for proportional adjustment, so that the multi-way valve of the present application has a mode switching function and a proportional adjustment function, expanding the adaptability of the multi-way valve.

[0017] In some embodiments, the valve core includes: a disk body, the disk body is provided with a first opening and a second opening; a hollow first protrusion and a hollow second protrusion, the first protrusion and the second protrusion are arranged on the disk body at intervals, the inner cavity of the first protrusion is connected to the first opening to define the first flow channel, and the inner cavity of the second protrusion is connected to the second opening to define the second flow channel. The molding difficulty of the first flow channel and the second flow channel is reduced, thereby reducing the molding difficulty of the valve core and improving the manufacturing efficiency of the multi-way valve.

[0018] In some embodiments, the multi-way valve further comprises a driving member, the driving member is connected to the valve core to drive the valve core to rotate; on the rotation axis of the valve core, the driving member and the plurality of valve ports are respectively arranged on opposite side walls of the valve body. While ensuring that the valve core can effectively rotate relative to the valve body, the difficulty of setting the driving member can be reduced, and the driving member can be prevented from obstructing the connection between the valve port and the external structural member, so as to reduce the difficulty of assembling the multi-way valve.

DETAILED DESCRIPTION

[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments.

[0051] Reference to "embodiments" in this application means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0052] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "attached" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements.

[0054] In the embodiments of the present application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary descriptions and should not constitute any limitation to the present application.

[0055] The term "plurality" used in the present application refers to two or more (including two).

[0056] Valves are used in thermal management systems. They are mainly used to switch the connection between different circuits in the thermal management system according to demand, so that the thermal management system can meet the heating or cooling needs of the vehicle for the motor, battery or passenger compartment, ensuring the comfort, safety and cruising range of the vehicle.

[0057] However, the applicant has noticed that in order to achieve the connection relationship between different circuits, multiple valves are usually required to be set up, but the coordination of multiple valves will cause the thermal management system to occupy a larger space and have a lower degree of integration, thereby increasing the cost and control difficulty of the thermal management system.

[0058] In order to solve the above problems, the embodiment of the present application provides a multi-way valve 1000. The specific solution is to set at least five valve ports 110 on the valve body 100, and set a first flow channel 210 and a second flow channel 220 spaced apart on the valve core 200, and the first flow channel 210 is set to be able to communicate with the two valve ports 110. In this way, when the valve core 200 rotates, the first flow channel 210 can be used to connect different valve ports 110 to achieve switching between different modes, thereby achieving the connection relationship between different circuits in the switching thermal management system, and the second flow channel 220 is set to be able to communicate with two valve ports 110 or with three valve ports 110. When the valve core 200 rotates to connect the second flow channel 220 When two different valve ports 110 are connected, switching between different modes can be achieved. When the valve core 200 is rotated to make the second flow channel 220 connect to three different valve ports 110 and change the connecting area between the second flow channel 220 and at least one valve port 110, proportional adjustment of the valve port 110 can be achieved, so that the multi-way valve 1000 of the present application can replace a three-way valve and a four-way valve at the same time, improve the integration of the multi-way valve 1000, and expand the adaptability of the multi-way valve 1000. Moreover, since the present application only has the first flow channel 210 and the second flow channel 220, the structure of the valve core 200 can also be simplified, thereby making the multi-way valve 1000 simple in structure, reducing the manufacturing difficulty of the multi-way valve 1000 and improving the manufacturing efficiency.

[0059] The multi-way valve 1000 of the embodiment of the present application is described below with reference to the accompanying drawings.

[0060] Combination Figure 1-Figure 4 As shown, a multi-way valve 1000 according to an embodiment of the present application includes a valve body 100 and a valve core 200 .

[0061] Among them, combined Figure 1 , Figure 2 and Figure 3 As shown, the valve body 100 is provided with at least five valve ports 110. The valve ports 110 are used to achieve communication between the inside and outside of the multi-way valve 1000, thereby ensuring that the external medium can flow into the interior of the multi-way valve 1000 through the valve ports 110, and the external medium flowing into the interior of the multi-way valve 1000 can flow out through the valve ports 110, so as to achieve the transportation of the external medium.

[0062] When different valve ports 110 are connected, switching between multiple modes can be achieved.

[0063] In some embodiments, the valve port 110 is connected to an external pipeline, such as a water pump, a motor cooling pipeline, a battery heating pipeline and a cooling pipeline, a cabin heating pipeline, etc., so that the valve port 110 can be used to discharge the external medium to the external pipeline or the external pipeline can be used to transport the external medium to the multi-way valve 1000, so that the multi-way valve 1000 can be used to control the flow direction of the external medium.

[0064] It should be noted that the external medium mentioned here can be water, refrigerant or other liquids.

[0065] The valve core 200 is rotatably disposed in the valve body 100. Figure 4 , Figure 5 and Figure 6 As shown, the valve core 200 includes a first flow channel 210 and a second flow channel 220, the first flow channel 210 and the second flow channel 220 are arranged at intervals, the first flow channel 210 is used to communicate with two valve ports 110, and the valve core 200 rotates so that the first flow channel 210 is used to communicate with different valve ports 110. That is, when the valve core 200 rotates relative to the valve body 100, the first flow channel 210 can be controlled to communicate with different valve ports 110, thereby realizing switching between multiple modes, so that the multi-way valve 1000 has the function of mode switching.

[0066] It should also be noted that the communication mentioned here means that the external medium between the two can flow mutually. For example, when the two valve ports 110 are connected through the first flow channel 210, the external medium flowing through one of the valve ports 110 can flow to the other valve port 110 through the first flow channel 210, and correspondingly, the external medium flowing through the other valve port 110 can also flow to one of the valve ports 110 through the first flow channel 210, so as to realize the flow of the external medium, thereby ensuring the working performance of the thermal management system.

[0067] The second flow channel 220 has a switching mode and a proportional adjustment mode. The valve core 200 rotates to make the second flow channel 220 switch between the switching mode and the proportional adjustment mode. In the switching mode, the second flow channel 220 is used to communicate with two valve ports 110 and connect to different valve ports 110 when the valve core 200 rotates. In the proportional adjustment mode, the second flow channel 220 is used to communicate with at least three valve ports 110 and change the connection area with at least one valve port 110 when the valve core 200 rotates. Here, it means that the second flow channel 220 can be connected to two valve ports 110 or to at least three valve ports 110, wherein at least three valve ports 110 refer to three valves 110 or more than three valves 110, that is, in the proportional adjustment mode, the second flow channel 220 is used to be connected to three valve ports 110 or to be connected to more than three valves 110. When the second flow channel 220 is connected to two valve ports 110 and the valve core 200 rotates, the second flow channel 220 can be controlled to be connected to different valve ports 110, thereby realizing switching between multiple modes; when the second flow channel 220 is connected to at least three valve ports 110 and the valve core 200 rotates, the connecting area between the second flow channel 220 and at least one valve port 110 can be changed, thereby realizing proportional adjustment, so that the multi-way valve 1000 of the present application can have both mode switching function and proportional adjustment function, thereby expanding the adaptability of the multi-way valve 1000.

[0068] In a specific example, Fig.10 , Fig.13 , Fig.16 and Fig.19 As shown, in the proportional adjustment mode, the second flow channel 220 is used to communicate with three valve ports 110 arranged in sequence, and when the valve core 200 rotates, the communication area of ​​the valve ports 110 connected to both ends of the second flow channel 220 can be changed.

[0069] At the same time, through the above-mentioned setting, the multi-way valve 1000 of the present application can also replace a three-way valve and a four-way valve, thereby improving the integration of the multi-way valve 1000. In this way, the multi-way valve 1000 is applied to the thermal management system, which can effectively improve the integration of the thermal management system and reduce the control difficulty and cost of the thermal management system.

[0070] It is worth noting that the present application can achieve mode switching and proportional adjustment through the cooperation of the first flow channel 210 and the second flow channel 220. This can not only expand the adaptability of the multi-way valve 1000, but also simplify the structure of the multi-way valve 1000, making the structure of the multi-way valve 1000 simple, thereby reducing the manufacturing difficulty of the multi-way valve 1000.

[0071] That is to say, the multi-way valve 1000 of the present application has a simple structure, low manufacturing difficulty and a high degree of integration. It can simultaneously meet the mode switching function and proportional adjustment function of the combination of a three-way valve and a four-way valve to meet the needs of the thermal management system and reduce the cost of the thermal management system.

[0072] In a specific example, when the valve core 200 rotates relative to the valve body 100, the valve core 200 drives the first flow channel 210 and the second flow channel 220 to rotate synchronously, so that the first flow channel 210 can be connected to different valve ports 110, and the second flow channel 220 can be connected to valve ports 110 at different positions and different numbers, and the connection area between the second flow channel 220 and at least one valve port 110 can be controlled to ensure the working performance of the multi-way valve 1000.

[0073] It should also be noted that when the first flow channel 210 and the second flow channel 220 are rotated to overlap or partially overlap with the corresponding valve port 110, the first flow channel 210 and the second flow channel 220 can be connected to the valve port 110. At this time, the external medium can flow into the first flow channel 210 and the second flow channel 220 through the valve port 110, and the external medium in the first flow channel 210 and the second flow channel 220 can also be discharged through the valve port 110; when the first flow channel 210 and the second flow channel 220 are rotated to be misaligned with the valve port 110, the first flow channel 210 and the second flow channel 220 are not connected to the valve port 110. At this time, the external medium cannot flow into the first flow channel 210 and the second flow channel 220, and the external medium located in the first flow channel 210 and the second flow channel 220 cannot be discharged.

[0074] In addition, by changing the overlapping range between the second flow channel 220 and the corresponding valve port 110 , the communication area between the second flow channel 220 and the corresponding valve port 110 can be changed.

[0075] Specifically, the larger the overlapping range between the second flow channel 220 and the corresponding valve port 110 is, the larger the communicating area between the second flow channel 220 and the corresponding valve port 110 is, which facilitates proportional adjustment.

[0076] It can be seen from the above structure that the multi-way valve 1000 of the embodiment of the present application is provided with a first flow channel 210 and a second flow channel 220 spaced apart on the valve core 200, and at least five valve ports 110 are provided on the valve body 100, and the valve core 200 is rotatably provided in the valve body 100, so that the first flow channel 210, the second flow channel 220 and the plurality of valve ports 110 can be used to cooperate with each other to make the structure of the multi-way valve 1000 of the present application simple, and the multi-way valve 1000 can also have a switching function and a proportional adjustment function at the same time, so that a multi-way valve 1000 can simultaneously replace a three-way valve and a four-way valve, thereby improving the integration of the multi-way valve 1000 and expanding the adaptability of the multi-way valve 1000, so that the multi-way valve 1000 is applied to the thermal management system, which can effectively improve the integration of the thermal management system and reduce the control difficulty and cost of the thermal management system.

[0077] It can be understood that, compared with the prior art, the present application sets a first flow channel 210 and a second flow channel 220 on the valve core 200, and sets at least five valve ports 110 on the valve body 100. The first flow channel 210, the second flow channel 220 and the multiple valve ports 110 cooperate with each other. While simplifying the structure of the multi-way valve 1000, it can also improve the integration of the multi-way valve 1000 and expand the adaptability of the multi-way valve 1000, so as to improve the integration of the thermal management system and reduce the control difficulty and cost of the thermal management system.

[0078] In some embodiments, in combination Figure 1 , Figure 2 and Figure 3 As shown, at least five valve ports 110 are provided on the bottom wall of the valve body 100. The valve ports 110 are formed on the bottom surface of the valve body 100, which can reduce the difficulty of molding the valve ports 110 on the one hand, and reduce the difficulty of matching the valve ports 110 with the first flow channel 210 and the second flow channel 220 on the other hand. At the same time, water inlet and outlet can be realized at the same end of the multi-way valve 1000, further simplifying the structure of the multi-way valve 1000, and making the volume of the multi-way valve 1000 smaller and easier to control.

[0079] In other words, the multi-way valve 1000 of the present application has a simple and compact structure.

[0080] Optionally, the valve body 100 and the valve core 200 are coaxially arranged to ensure that the valve core 200 can effectively rotate relative to the valve body 100, thereby facilitating mode switching and proportional adjustment using the multi-way valve 1000.

[0081] In some embodiments, in combination Figure 4 , Figure 5 and Figure 7 As shown, the valve body 100 has a receiving cavity 120 with a top opening, and the valve core 200 is rotatably disposed in the receiving cavity 120 through the top opening to achieve rotational coordination between the valve body 100 and the valve core 200, while also reducing the difficulty of assembling the valve body 100 and the valve core 200.

[0082] In some embodiments, Figure 1 and Figure 2 As shown, the valve body 100 also includes an upper cover 130, which can be detachably connected to the opening of the accommodating chamber 120 to close the opening, thereby facilitating the use of the valve body 100 to protect the valve core 200 and extend the service life of the valve core 200. At the same time, it can also prevent external debris from entering the accommodating chamber 120, ensure that the valve core 200 can effectively rotate relative to the valve body 100, and ensure the working performance of the multi-way valve 1000.

[0083] Alternatively, if Figure 1 As shown, the upper cover 130 is detachably connected to the opening of the accommodating cavity 120 via a fastener 140 to reduce the difficulty of connecting the upper cover 130 .

[0084] The fastener 140 mentioned here may be a bolt, a screw, etc.

[0085] In some embodiments, in combination Figure 2 and Figure 3As shown, at least five valve ports 110 include a central valve port 111 and multiple peripheral valve ports 112, the peripheral valve ports 112 are spaced apart around the central valve port 111, the first flow channel 210 is connected to the central valve port 111, the valve core 200 rotates so that the first flow channel 210 is connected to different peripheral valve ports 112, and the second flow channel 220 is used to connect at least two peripheral valve ports 112 to switch between the switching mode and the proportional adjustment mode. What is meant here is that the first flow channel 210 is always connected to the central valve port 111, and when the valve core 200 rotates relative to the valve body 100, the first flow channel 210 can be connected to different peripheral valve ports 112, so that the central valve port 111 can be connected to different peripheral valve ports 112 during the rotation of the valve core 200, and each time a peripheral valve port 112 is connected, a mode can be switched, thereby realizing switching between multiple modes; the second flow channel 220 is connected to at least two peripheral valve ports 112, so that the second flow channel 220 switches between the switching mode and the proportional adjustment mode, so that the multi-way valve 1000 can switch between the switching mode and the proportional adjustment mode, and the multi-way valve 1000 has a switching function and a proportional adjustment function, so as to realize the use of a multi-way valve 1000 to replace a three-way valve and a four-way valve at the same time, improve the integration of the multi-way valve 1000, and ensure the function of the multi-way valve 1000.

[0086] in, Fig.10 , Fig.13 , Fig.16 and Fig.19 Schematic diagrams showing the first flow channel 210 being in communication with different peripheral valve ports 112 are shown respectively.

[0087] It should be noted that the second flow channel 220 mentioned above is used to connect at least two peripheral valve ports 112, which means that the second flow channel 220 can be connected to two peripheral valve ports 112 at the same time, and can also be connected to more than two peripheral valve ports 112 at the same time. When the second flow channel 220 is connected to two peripheral valve ports 112 at the same time, during the rotation of the valve core 200, the second flow channel 220 can be controlled to be connected to two different peripheral valve ports 112, and the connected peripheral valve ports 112 are different, which can make the operation mode of the multi-way valve 1000 different, thereby realizing switching between multiple modes. That is, the second flow channel 220 has a switching mode; when the second flow channel 220 is connected to multiple peripheral valve ports 112 (such as three peripheral valve ports 112) at the same time, during the rotation of the valve core 200, the second flow channel 220 can be controlled to connect with three different peripheral valve ports 112 and the connection area between the second flow channel 220 and at least one peripheral valve port 112 can be changed. The connection area is different, and the flow rate of the external medium flowing through the peripheral valve port 112 is also different, thereby realizing mode switching and proportional regulation, that is, the second flow channel 220 has a proportional regulation mode.

[0088] in, Fig. 9 , Fig.11 , Fig.12 , Fig.14 Schematic diagrams showing the second flow channel 220 being connected to two different peripheral valve ports 112; Fig.10 , Fig.13 , Fig.16 and Fig.19 Schematic diagrams showing the second flow channel 220 being in communication with three different peripheral valve ports 112 are shown respectively.

[0089] In some embodiments, in combination Figure 4 , Figure 6 and Figure 7 As shown, the valve core 200 is provided with an annular blocking protrusion 230, which abuts against the valve body 100 and is arranged around the central valve port 111. By abutting the blocking protrusion 230 against the valve body 100, the blocking protrusion 230 can be used to reduce the contact area between the valve core 200 and the valve body 100, thereby reducing the friction between the valve core 200 and the valve body 100, ensuring that the valve core 200 can effectively rotate relative to the valve body 100, and reducing the difficulty of rotation, thereby ensuring the working performance of the multi-way valve 1000.

[0090] In addition, setting the blocking protrusion 230 around the central valve port 111 can also prevent the blocking protrusion 230 from blocking the central valve port 111, thereby preventing the blocking protrusion 230 from blocking the external medium from flowing through the central valve port 111, thereby ensuring the sealing and flow guiding effect of the central valve port 111.

[0091] Optionally, the blocking protrusion 230 is integrally formed with the valve core 200. That is, the blocking protrusion 230 is integrally formed on the valve core 200 to reduce the difficulty of forming the blocking protrusion 230, and at the same time, the position stability of the blocking protrusion 230 can be improved to ensure the working performance of the blocking protrusion 230.

[0092] In some embodiments, Figure 3 and Figure 8 As shown, the plurality of peripheral valve ports 112 include a first valve port 1121, a second valve port 1122, a third valve port 1123 and a fourth valve port 1124. The first valve port 1121 and the second valve port 1122 are symmetrically arranged relative to the central valve port 111, and the third valve port 1123 and the fourth valve port 1124 are symmetrically arranged relative to the central valve port 111. This reduces the difficulty of forming the plurality of peripheral valve ports 112, and ensures that when the valve core 200 rotates, the first flow channel 210 can communicate with the central valve port 111 and one of the peripheral valve ports 112, and enables the second flow channel 220 to communicate with at least two peripheral valve ports 112, so as to facilitate the switching function and the proportional adjustment function of the multi-way valve 1000 and improve the integration of the multi-way valve 1000.

[0093] In some embodiments, Figure 8As shown, the central valve port 111 is arranged at the central position of the bottom wall of the valve body 100, and a plurality of peripheral valve ports 112 are arranged around the central valve port 111 at intervals, and the distance between the same peripheral valve port 112 and two adjacent peripheral valve ports 112 is consistent, so that the first valve port 1121, the second valve port 1122, the third valve port 1123 and the fourth valve port 1124 are evenly arranged in the circumferential direction of the central valve port 111.

[0094] Through the above configuration, the multi-way valve 1000 can have multiple modes to expand the adaptability of the multi-way valve 1000.

[0095] In a specific example, Fig. 9 As shown, in the first working mode, the valve core 200 rotates to make the first flow channel 210 communicate with the central valve port 111 and the third valve port 1123 respectively, and the second flow channel 220 communicates with the second valve port 1122 and the fourth valve port 1124 respectively.

[0096] like Fig.10 As shown, in the second working mode, the valve core 200 rotates to make the first flow channel 210 communicate with the central valve port 111 and the third valve port 1123 respectively, and the second flow channel 220 communicates with the first valve port 1121, the second valve port 1122, and the fourth valve port 1124 respectively.

[0097] like Fig.11 As shown, in the third working mode, the valve core 200 rotates to make the first flow channel 210 communicate with the central valve port 111 and the third valve port 1123 respectively, and the second flow channel 220 communicates with the first valve port 1121 and the fourth valve port 1124 respectively.

[0098] like Fig.12 As shown, in the fourth working mode, the valve core 200 rotates to make the first flow channel 210 communicate with the central valve port 111 and the fourth valve port 1124 respectively, and the second flow channel 220 communicates with the first valve port 1121 and the third valve port 1123 respectively.

[0099] like Fig.13 As shown, in the fifth working mode, the valve core 200 rotates to connect the first flow channel 210 with the central valve port 111 and the fourth valve port 1124 respectively, and the second flow channel 220 with the first valve port 1121, the third valve port 1123, and the second valve port 1122 respectively.

[0100] like Fig.14 As shown, in the sixth working mode, the valve core 200 rotates to make the first flow channel 210 communicate with the central valve port 111 and the fourth valve port 1124 respectively, and the second flow channel 220 communicates with the third valve port 1123 and the second valve port 1122 respectively.

[0101] like Fig.15As shown, in the seventh working mode, the valve core 200 rotates to make the first flow channel 210 communicate with the central valve port 111 and the first valve port 1121 respectively, and the second flow channel 220 communicates with the third valve port 1123 and the second valve port 1122 respectively.

[0102] like Fig.16 As shown, in the eighth working mode, the valve core 200 rotates to make the first flow channel 210 communicate with the central valve port 111 and the first valve port 1121 respectively, and the second flow channel 220 communicates with the third valve port 1123, the second valve port 1122, and the fourth valve port 1124 respectively.

[0103] like Fig.17 As shown, in the ninth working mode, the valve core 200 rotates to make the first flow channel 210 communicate with the central valve port 111 and the first valve port 1121 respectively, and the second flow channel 220 communicates with the second valve port 1122 and the fourth valve port 1124 respectively.

[0104] like Fig.18 As shown, in the tenth working mode, the valve core 200 rotates to make the first flow channel 210 communicate with the central valve port 111 and the second valve port 1122 respectively, and the second flow channel 220 communicates with the fourth valve port 1124 and the first valve port 1121 respectively.

[0105] like Fig.19 As shown, in the eleventh working mode, the valve core 200 rotates to make the first flow channel 210 communicate with the central valve port 111 and the second valve port 1122 respectively, and the second flow channel 220 communicates with the fourth valve port 1124, the first valve port 1121, and the third valve port 1123 respectively.

[0106] like Fig. 20 As shown, in the twelfth working mode, the valve core 200 rotates to make the first flow channel 210 communicate with the central valve port 111 and the second valve port 1122 respectively, and the second flow channel 220 communicates with the first valve port 1121 and the third valve port 1123 respectively.

[0107] It should be noted that the above working modes are only examples and do not represent limitations on this application.

[0108] In summary, the present application creatively sets the position of the valve port 110 and sets the matching relationship between the first flow channel 210, the second flow channel 220 and the valve port 110, so that the multi-way valve 1000 can output six additional modes in addition to the modes output by the combination of traditional three-way valves and four-way valves. This can greatly expand the adaptability of the multi-way valve 1000 without increasing the cost of the multi-way valve 1000.

[0109] in, Fig. 9 The first working mode in Fig.11The third working mode in Fig.12 The fourth working mode in Fig.14 The sixth working mode in Fig.15 The seventh working mode in Fig.17 The ninth working mode in Fig.18 The tenth working mode and Fig. 20 The twelfth working mode in is used to play the function of mode switching; Fig.10 The second working mode in Fig.13 The fifth working mode in Fig.16 The eighth working mode in Fig.19 The eleventh working mode is used to perform a proportional regulation function. Compared with the combination of a traditional three-way valve and a four-way valve, the multi-way valve 1000 not only reduces the cost, but also further improves the breadth of its application.

[0110] In some embodiments, Figure 6 As shown, the second flow channel 220 is formed as an arc-shaped flow channel. In this way, when the external medium flows along the second flow channel 220, the resistance of the second flow channel 220 to the external medium can be reduced, thereby reducing the pressure drop and flow loss of the external medium, and ensuring the performance of the multi-way valve 1000.

[0111] In some embodiments, the central angle of the second flow channel 220 is not less than 180°. In other words, the central angle of the second flow channel 220 is greater than 180° to ensure that when the valve core 200 rotates, the second flow channel 220 can communicate with at least two peripheral valve ports 112, thereby ensuring the performance of the multi-way valve 1000 and facilitating the switching function and proportional adjustment function of the multi-way valve 1000.

[0112] In a specific example, the center angle of the second flow channel 220 is equal to 180°. When the center angle of the second flow channel 220 is too small, the second flow channel 220 cannot be connected to at least three peripheral valve ports 112 at the same time, thereby causing the multi-way valve 1000 to fail to have a proportional adjustment function; when the center angle of the second flow channel 220 is too large, the second flow channel 220 will occupy the layout space of the first flow channel 210, thereby causing the first flow channel 210 to be unable to be arranged on the valve core 200, or causing the first flow channel 210 and the second flow channel 220 to be unable to be arranged at intervals, thereby affecting the working performance of the multi-way valve 1000.

[0113] Therefore, the present application sets the central angle of the second flow channel 220 to be equal to 180°. In this way, while ensuring that the second flow channel 220 can simultaneously connect to at least three peripheral valve ports 112, it can also avoid the second flow channel 220 occupying the layout space of the first flow channel 210, and enable the first flow channel 210 and the second flow channel 220 to be arranged at intervals to ensure the working performance of the multi-way valve 1000.

[0114] In some embodiments, Figure 6 As shown, the first flow channel 210 includes a first portion 211 and a second portion 212, the first end of the first portion 211 is in communication with the central valve port 111, the second end of the first portion 211 is in communication with the second portion 212, the second portion 212 is formed as an arc-shaped flow channel, and the second portion 212 is used to communicate with different peripheral valve ports 112. By configuring the first flow channel 210 to include the first portion 211 and the second portion 212, the first flow channel 210 can be in communication with the central valve port 111 and one of the peripheral valve ports 112, respectively, so that when the valve core 200 rotates relative to the valve body 100, the central valve port 111 can be in communication with different peripheral valve ports 112, thereby realizing switching between multiple modes.

[0115] At the same time, by forming the second part 212 into an arc-shaped flow channel, while reducing the difficulty of molding the second part 212, the resistance of the second part 212 to the external medium can also be reduced, thereby reducing the pressure drop and flow loss of the external medium and ensuring the performance of the multi-way valve 1000.

[0116] In some embodiments, the valve core 200 rotates so that the first flow channel 210 can be connected to any one of the plurality of peripheral valve ports 112. That is, the first flow channel 210 can make the central valve port 111 be connected to any peripheral valve port 112, so that the multi-way valve 1000 can have multiple working modes and can switch between the multiple working modes without increasing the cost of the multi-way valve 1000, which greatly expands the adaptability of the multi-way valve 1000.

[0117] in, Fig.10 , Fig.13 , Fig.16 and Fig.19 Schematic diagrams showing the first flow channel 210 being connected to the third valve port 1123 , the fourth valve port 1124 , the first valve port 1121 , and the second valve port 1122 , respectively.

[0118] Optionally, the central angle of the second portion 212 is not less than 90°. In other words, the central angle of the second portion 212 is greater than 90° to ensure that when the valve core 200 rotates, the second portion 212 can always communicate with one peripheral valve port 112, thereby ensuring the performance of the multi-way valve 1000.

[0119] In a specific example, the center angle of the second portion 212 is equal to 90°. If the center angle of the second portion 212 is too small, the second portion 212 will not be able to communicate with the peripheral valve port 112 when the valve core 200 rotates. Fig.10 and Fig.11 As shown in FIG. 1 , if the center angle of the second portion 212 is too small, the second portion 212 will be Fig.10 Rotate the position to Fig.11position, the peripheral valve port 112 cannot be completely connected with the second portion 212, thereby affecting the working performance of the multi-way valve 1000; when the central angle of the second portion 212 is too large, on the one hand, there is a risk that the second portion 212 is connected to two peripheral valve ports 112 at the same time, and on the other hand, it will also cause the first flow channel 210 and the second flow channel 220 to be unable to be spaced apart, affecting the working performance of the multi-way valve 1000.

[0120] Therefore, the present application sets the central angle of the second portion 212 to be equal to 90°, so that when the second portion 212 completely covers one of the peripheral valve ports 112, the second portion 212 can be spaced apart from the peripheral valve port 112 adjacent to the peripheral valve port 112 (combined with Fig. 9 , Fig.10 and Fig.11 As shown), this ensures that the second portion 212 can always be connected to a peripheral valve port 112, while also preventing the second portion 212 from occupying the layout space of the second flow channel 220, and allowing the first flow channel 210 and the second flow channel 220 to be spaced apart to ensure the working performance of the multi-way valve 1000.

[0121] In summary, there are a first flow channel 210 and a second flow channel 220 on the valve core 200. In the circumferential direction of the valve core 200, the second flow channel 220 occupies an arc of 180°, and the first flow channel 210 occupies an arc of 90°. The 180° flow channel can be used to realize both the mode switching function and the proportional adjustment function, and the 90° flow channel is only used to realize the mode switching function.

[0122] In some embodiments, the central angle of the second portion 212 is greater than the central angle corresponding to the peripheral valve port 112 and less than or equal to the central angle corresponding to the area between the centers of two adjacent peripheral valve ports 112. This ensures that the second portion 212 can effectively connect to one of the peripheral valve ports 112, and avoids that when one end of the second portion 212 is connected to one of the peripheral valve ports 112, the other end of the second portion 212 is simultaneously connected to one of the peripheral valve ports 112, thereby ensuring that the second portion 212 can always connect to one of the peripheral valve ports 112, thereby ensuring the working performance of the multi-way valve 1000.

[0123] In some embodiments, the valve core 200 rotates so that the second flow channel 220 can be connected to any two adjacent ones or any three adjacent ones of the plurality of peripheral valve ports 112. That is to say, during the rotation of the valve core 200, the second flow channel 220 can connect any two adjacent peripheral valve ports 112, or any three adjacent peripheral valve ports 112, wherein when any two adjacent peripheral valve ports 112 are connected, it can be used to achieve function switching, and when any three adjacent peripheral valve ports 112 are connected, it can be used to achieve proportional adjustment, so that the multi-way valve 1000 of the present application has a mode switching function and a proportional adjustment function, and expands the adaptability of the multi-way valve 1000.

[0124] In some embodiments, in combination Figure 5 and Figure 6 As shown, the valve core 200 includes a disc body 240, a hollow first protrusion 250 and a hollow second protrusion 260, the disc body 240 is provided with a first opening 241 and a second opening 242, the first protrusion 250 and the second protrusion 260 are arranged at intervals on the disc body 240, the inner cavity of the first protrusion 250 is connected with the first opening 241 to define the first flow channel 210, and the inner cavity of the second protrusion 260 is connected with the second opening 242 to define the second flow channel 220. That is to say, the present application can form the first flow channel 210 and the second flow channel 220 by providing the hollow first protrusion 250 and the hollow second protrusion 260 and providing the first opening 241 and the second opening 242 on the disc body 240, so as to reduce the molding difficulty of the first flow channel 210 and the second flow channel 220, thereby reducing the molding difficulty of the valve core 200 and improving the manufacturing efficiency of the multi-way valve 1000.

[0125] In some embodiments, part of the side wall of the disc body 240 protrudes toward one side to form a hollow first protrusion 250 and a hollow second protrusion 260, and the first protrusion 250 and the second protrusion 260 are both formed with an inner cavity. In this way, while reducing the difficulty of molding the first protrusion 250 and the second protrusion 260, the structural strength of the first protrusion 250 and the second protrusion 260 can be ensured, and it is easy to achieve the connection between the first protrusion 250 and the first opening 241 and the connection between the second protrusion 260 and the second opening 242, thereby reducing the difficulty of molding the first flow channel 210 and the second flow channel 220, and ensuring the structural stability of the first flow channel 210 and the second flow channel 220, thereby ensuring the diversion effect of the first flow channel 210 and the second flow channel 220.

[0126] In some embodiments, the multi-way valve 1000 further includes a driving member connected to the valve core 200 to drive the valve core 200 to rotate, thereby ensuring that the valve core 200 can effectively rotate relative to the valve body 100 to ensure the working performance of the multi-way valve 1000.

[0127] Optionally, the driving member is a driving motor, which can ensure the driving effect of the driving member while utilizing the driving member to drive the valve core 200 to rotate.

[0128] In some embodiments, Figure 5 As shown, the valve core 200 includes a connecting shaft 270, and the valve core 200 is connected to the driving member via the connecting shaft 270, so that the driving member can be used to drive the valve core 200 to rotate, and the difficulty of matching the driving member with the valve core 200 can also be reduced.

[0129] Optionally, on the rotation axis of the valve core 200, the driving member and the plurality of valve ports 110 are respectively arranged on opposite side walls of the valve body 100. This reduces the difficulty of setting the driving member and also prevents the driving member from obstructing the connection between the valve ports 110 and the external structural member, thereby reducing the difficulty of assembling the multi-way valve 1000.
