At the same time, the terms such as "on" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present disclosure. The change or adjustment of their relative relationship should also be regarded as the scope of the implementation of the present disclosure without substantially changing the technical contents.
[0029] In order to more clearly understand the present disclosure, various embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.
[0030] The present disclosure provides a valve assembly 1. Figure 1 , Figure 2 and Figure 3 The valve assembly 1 includes a valve block 300, a first valve member 100 and a second valve member 200. The valve block 300 is provided with a first receiving chamber 310 and a second receiving chamber 320, which are used to receive the first valve member 100 and the second valve member 200 respectively. The valve block 300 is also provided with a first port 301, a second port 302 and a third port 303 communicating with the first receiving chamber 310, and a fourth port 304, a fifth port 305 and a sixth port 306 communicating with the second receiving chamber 320. The first valve member 100 is at least partially installed in the first receiving chamber 310, and can operatively connect at least one of the second port 302 and the third port 303 to the first port 301 (to be described later). The second valve member 200 is at least partially installed in the second receiving chamber 320, and can operatively connect at least one of the fifth port 305 and the sixth port 306 to the fourth port 304 (to be described later) to switch the working mode of the valve assembly 1.
[0031] Specifically, Figure 3 As shown, the valve block 1 can be roughly plate-shaped and an integrated component with a simple structure and easy to manufacture, which can improve the integration of the valve assembly 1 and facilitate the installation of the valve assembly 1. In one embodiment, the first receiving chamber 310 and the second receiving chamber 320 can be arranged on the same side of the valve block 300 (such as Figure 3The first port 301, the second port 302 and the third port 303 may be located at the bottom wall 319 of the first receiving chamber 310, and / or the fourth port 304, the fifth port 305 and the sixth port 306 may be located at the bottom wall 329 of the second receiving chamber 320. Such an arrangement may enable the first valve member 100 and / or the second valve member 200 matched with the above ports to be configured as a butterfly valve, which can effectively reduce the height of the valve assembly 1 compared to a ball valve, further improve the integration, and reduce the occupied space.
[0032] See also Figure 4 The valve block 300 also includes a first flow channel 330 and a second flow channel 340, and a first communication port 311, a second communication port 312, a third communication port 313, a fourth communication port 314, a fifth communication port 315 and a sixth communication port 316 that can be communicated with an external element (such as a flow channel plate). The first flow channel 330 and the second flow channel 340 can be arranged roughly in parallel and located on both outer sides of the first port to the sixth port 301-306. The second port 302 and the fifth port 305 can be communicated with the first flow channel 330, and the third port 303 and the sixth port 306 can be communicated with the second flow channel 340, so that the interior of the valve block 300 can form a roughly U-shaped channel, wherein the first receiving chamber 310 and the second receiving chamber 320, especially the first to third ports 301-303 and the fourth to sixth ports 304-306 therein, can be located at the two diagonals of the U-shaped channel, such as Figure 3 and Figure 4 shown.
[0033] Please continue to see Figure 4 The first communication port 311 and the fourth communication port 314 of the valve block 300 are respectively located at the two ends of the first flow channel 330, and the connection point between the second port 302 and the first flow channel 330 and the connection point between the fifth port 305 and the first flow channel 330 are located between the first communication port 311 and the fourth communication port 314. The third communication port 313 and the sixth communication port 316 are respectively located at the two ends of the second flow channel 340, and the connection point between the third port 303 and the second flow channel 340 and the connection point between the sixth port 306 and the second flow channel 340 are located between the third communication port 313 and the sixth communication port 316. The second communication port 312 is communicated with the first port 301, and the fifth communication port 315 is communicated with the fourth port 304.
[0034] Preferably, the first communication port 311, the second communication port 312 and the third communication port 313 may be located on the first end surface (eg, Figure 4 The fourth communication port 314, the fifth communication port 315 and the sixth communication port 316 are located on the second end face (such as the left end face) of the valve block 300 which is arranged opposite to the first end face. Figure 4Such an arrangement can make the structure of the valve assembly 1 more compact and easy to install on an external component (such as a flow channel plate).
[0035] Please continue to see Figure 4 , the valve assembly 1 may further include a first one-way valve 10 and a second one-way valve 20. The first one-way valve 10 is disposed in the first flow channel 330 and is located between the connection point between the second port 302 and the first flow channel 330 and the connection point between the fifth port 305 and the first flow channel 330 (i.e., the first port 302 and the fifth port 305 are located on both sides of the first one-way valve 10). The first one-way valve 10 allows one-way flow from the second port 302 to the fifth port 305, or in other words, allows one-way flow from the first communication port 311 to the fourth communication port 314. The second one-way valve 20 is disposed in the second flow channel 340 and is located between the connection point between the third port 303 and the second flow channel 340 and the connection point between the sixth port 306 and the second flow channel 340 (i.e., the third port 303 and the sixth port 306 are located on both sides of the second one-way valve 20). The second check valve 20 allows a one-way flow from the third port 303 to the sixth port 306 , or in other words, allows a one-way flow from the third communication port 313 to the sixth communication port 316 .
[0036] In order to facilitate the installation of the first one-way valve 10 and the second one-way valve 20, the first flow channel 330 and the second flow channel 340 at least have a first section with a larger inner diameter and a second section with a smaller inner diameter. The outer diameter of the first one-way valve 10 is smaller than the inner diameter of the first section of the first flow channel 330 and larger than the inner diameter of the second section, wherein the first section can be penetrated to one end of the valve body 10, for example, to the fourth communication port 314, so that the first one-way valve 10 can be placed in the first flow channel 330 through the fourth communication port 314, and positioned by the second section, and installed in the first flow channel 330. Similarly, the outer diameter of the second one-way valve 20 is smaller than the inner diameter of the first section of the second flow channel 340 and larger than the inner diameter of the second section, wherein the first section can be penetrated to one end of the valve body, for example, to the sixth communication port 316, so that the second one-way valve 20 can be placed in the second flow channel 330 through the sixth communication port 316, and positioned by the second section, and installed in the second flow channel 340.
[0037] Preferably, the first one-way valve 10, the first connecting port 311 and the fourth connecting port 314 can be roughly coaxially arranged (that is, the first flow channel 330 can be roughly a straight flow channel), wherein the first one-way valve 10 is located in the first flow channel 330; and the second one-way valve 20, the third connecting port 313 and the sixth connecting port 316 can be roughly coaxially arranged (that is, the second flow channel 340 can be roughly a straight flow channel), wherein the second one-way valve 20 is located in the second flow channel 340. Such an arrangement can further improve the compactness of the valve assembly 1 and reduce the flow resistance compared to the one-way valve being located at the corner of the flow channel.
[0038] See also Figure 5 and Figure 6 The first valve member 100 can be a three-way butterfly valve, which can be detachably plugged into the first receiving chamber 310 for easy installation. The first valve member 100 includes three valve ports V1, V2 and V3, which are respectively connected to the first port 301, the second port 302 and the third port 303 of the valve block 300, and the first port 301 can be selectively connected to the second port 302 and / or the third port 303 through the different connection states of the three valve ports of the first valve member 100, thereby switching the connection state of the flow channel, and then realizing the switching between different working modes of the thermal management system.
[0039] For details, see Figures 5 to 9 The first valve member 100 includes a valve body 110, a valve core 120 located in the valve body 110, and an actuator 130 located outside the valve body 110 and capable of driving the valve core 120 to rotate. The valve body 110 may be substantially in the shape of a hollow column, and is provided with a first valve port V1, a second valve port V2, and a third valve port V3 running through the bottom thereof, which are respectively used to connect to the first port 301, the second port 302, and the third port 303 of the valve block 100.
[0040] The valve core 120 may be substantially in the shape of a circular plate, and is provided with a first through hole 121, a second through hole 122, and a third through hole 123, which may be connected to different valve ports when the valve core 120 is in different working positions, so as to realize the switching between different working modes of the first valve member 100. In one embodiment, the shape and size of the first through hole 121, the second through hole 122, and the third through hole 123 of the valve core 120 may be substantially the same as the first valve port V1, the second valve port V2, and the third valve port V3 of the valve body 110, such as Fig. 9 shown.
[0041] When the valve core 120 is located in the valve body 110 and is in the first working position (eg Fig. 9 ), the first through hole 121, the second through hole 122 and the third through hole 123 are aligned with the first valve port V1, the second valve port V2 and the third valve port V3 of the valve body 110 respectively, so that the three valve ports V1-V3 of the first valve member 100 can be connected to each other through the valve cavity in the valve body 110. In addition, because the first valve port V1, the second valve port V2 and the third valve port V3 of the first valve member 100 are connected to the first port 301, the second port 302 and the third port 303 of the valve block 300 respectively, when the valve core 120 is in the first working position, the first valve member 100 can make the first port 301 of the valve block 300 connected to the second port 302 and the third port 303.
[0042] When the valve core 120 is driven by the actuator 130 and moves along Fig. 9When the valve body 110 is rotated counterclockwise to the second working position (not shown), the first through hole 121 and the second through hole 122 can be aligned with the third valve port V3 and the first valve port V1 of the valve body 110 respectively, and the second valve port V2 is blocked by the valve core 120, so that the first valve port V1 and the third valve port V3 of the first valve member 100 can be connected through the valve cavity in the valve body 110, and the second valve port V2 is closed. In addition, because the first valve port V1, the second valve port V2 and the third valve port V3 of the first valve member 100 are connected to the first port 301, the second port 302 and the third port 303 of the valve block 300 respectively, when the valve core 120 is in the second working position, the first valve member 100 can make the first port 301 of the valve block 300 connected to the third port 303.
[0043] When the valve core 120 is driven by the actuator 130 and continues to move along Fig. 9 When the valve body 110 is rotated counterclockwise to the third working position (not shown), the third through hole 123 and the first through hole 121 can be aligned with the first valve port V1 and the second valve port V2 of the valve body 110 respectively, and the third valve port V3 is blocked by the valve core 120, so that the first valve port V1 and the second valve port V2 of the first valve member 100 can be connected through the valve cavity in the valve body 110, and the third valve port V3 is closed. In addition, because the first valve port V1, the second valve port V2 and the third valve port V3 of the first valve member 100 are connected to the first port 301, the second port 302 and the third port 303 of the valve block 300 respectively, when the valve core 120 is in the third working position, the first valve member 100 can make the first port 301 of the valve block 300 connected to the second port 302.
[0044] It can be seen that the first valve member 100 can operatively connect the first port 301 of the valve block 300 to at least one of the second port 302 and the third port 303 .
[0045] For details, please refer to Figure 6 The valve body 110 may include a valve seat 1101 and a valve cover 1102, which define a valve cavity for accommodating the valve core 120, wherein at least a portion of the valve seat 1101 can be directly inserted into the first receiving chamber 310 to facilitate the installation of the first valve member 100.
[0046] Preferably, the first valve member 100 may include a sealing member (not shown), which is at least disposed at the outer edge of the second valve port V2 and the third valve port V3 and abuts against the valve core 120, so that a sealed connection between the valve core 120 and the valve port can be achieved to prevent fluid leakage. Preferably, the first valve member 100 may also include an elastic member 140 (such as a spring) disposed between the valve cover 1102 and the valve core 120, which is used to make the valve core 120 press the sealing member to improve the sealing performance. Specifically, the actuator 130 can drive the valve core 120 through a driving shaft, and the elastic member 140 can be sleeved on the driving shaft, and the two ends elastically abut against the valve cover 1102 and the valve core 120 respectively. Preferably, the first valve member 100 may also include a thrust bearing, which is disposed between the elastic member 140 and the valve cover 1102 to reduce the rotation resistance of the valve core 120.
[0047] In addition, in order to limit the rotation angle of the valve core 120, the first valve member 100 may also be provided with a limiting mechanism. The limiting mechanism may include a limiting groove and a limiting block matched therewith, wherein one of the limiting groove and the limiting block is provided on the valve cover 1102, and the other is provided on the driving shaft, so that the rotation angle of the valve core 120 can be limited and its movement accuracy can be improved.
[0048] The second valve component 200 may also be a three-way butterfly valve, which can be detachably plugged into the second receiving chamber 320 for easy installation. The second valve component 200 also includes three valve ports, which are respectively connected to the fourth port 304, the fifth port 305 and the sixth port 306 of the valve block 300, and the fourth port 304 can be selectively connected to the fifth port 305 and / or the sixth port 306 through the different connection states of the three valve ports of the second valve component 200, thereby switching the connection state of the flow channel, and then realizing the switching between different working modes of the thermal management system.
[0049] For the specific structure of the second valve member 200, please refer to Figures 5 to 9 , which is similar in structure to the aforementioned first valve member 100, and will not be described in detail for the sake of brevity.
[0050] Please return to see Figure 1 and Figure 2 The valve assembly 1 may further include an expansion valve 400. The expansion valve 400 is detachably plugged into the sixth communication port 316 of the valve block 300 to facilitate installation of the valve assembly 1.
[0051] See also Fig.10 and Fig.11 The expansion valve 400 may be a ball valve having three states: fully open, throttling and fully closed. In the fully open state, the fluid may flow through the expansion valve 400 without throttling; in the throttling state, the fluid may flow through the expansion valve 400 with throttling; and in the fully closed state, the fluid cannot flow through the expansion valve 400.
[0052] Specifically, the expansion valve 400 may include a valve body 410, a valve core 420 located in the valve body 410, and an actuator 430 located outside the valve body 410 and used to drive the valve core 420. The valve body 410 may be provided with a protruding connector 411 for directly plugging into the sixth connecting port 316 of the valve block 300, so that it is easy to install and has a stable connection. The valve port of the expansion valve 400 passes through the connector 411 and can be in fluid communication with the valve block 300. The valve core 420 may be a spherical core. When the flow channel opening in the valve core 420 is aligned with the valve port of the valve body 410 (such as Fig.11 When the actuator 430 drives the valve core 420 to rotate until its flow channel opening is partially connected to the valve port, the expansion valve 400 is in a throttling state; when the actuator 430 drives the valve core 420 to rotate until its flow channel opening is not connected to the valve port, the expansion valve 400 is in a fully closed state.
[0053] Please return to see Figure 1 and Figure 2 The valve assembly 1 may further include a first sensor 30 and a second sensor 40. The first sensor 30 may be, for example, a pressure and temperature sensor. The first sensor 30 may be disposed in the flow channel between the second communication port 312 of the valve block 300 and the first port 301 to sense the pressure and temperature of the fluid in the flow channel. The second sensor 40 may be, for example, a temperature sensor. The second sensor 40 may be disposed in the flow channel between the fifth communication port 315 and the fourth port 304 of the valve block 300 to sense the temperature of the fluid in the flow channel.
[0054] The following will be combined with the attached Figure 4 The following describes different working modes of the valve assembly 1. When the valve assembly 1 is in different working modes, the flow channel thereof has different connection states.
[0055] The first communication port 311, the third communication port 313 and the fifth communication port 315 of the valve assembly 1 can be used as a fluid inlet, and the second communication port 312, the fourth communication port 314 and the sixth communication port 316 can be used as a fluid outlet. For example, the first communication port 311 of the valve assembly 1 can be connected to an external heat exchanger in a thermal management system, the third communication port 313 can be connected to an internal heat exchanger in the thermal management system, the fifth communication port 315 can be connected to a condenser in the thermal management system, and the second communication port 312, the fourth communication port 314 and the sixth communication port 316 as fluid outlets can be connected to other components in the thermal management system.
[0056] When the first valve component 100 is connected to the first port 301 and the third port 303, and the second valve component 200 is connected to the fourth port 304 and the sixth port 306, the valve assembly 1 is in the first working mode. At this time: the fluid flowing out of the external heat exchanger can flow into the valve assembly 1 through the first connecting port 311, and flow out of the valve assembly 1 through the first check valve 10 and the fourth connecting port 314 in sequence; the high-temperature and high-pressure fluid flowing out of the condenser can flow into the valve assembly 1 through the fifth connecting port 315, and flow out of the valve assembly 1 through the fourth port 304, the sixth port 306, the sixth connecting port 316 and the expansion valve 400 in sequence; the low-temperature and low-pressure fluid flowing out of the internal heat exchanger can flow into the valve assembly 1 through the third connecting port 313, and flow out of the valve assembly 1 through the third port 303, the first port 301 and the second connecting port 312 in sequence. It should be noted that since the fluids on both sides of the second one-way valve 20 are respectively in a high-temperature and high-pressure state and a low-temperature and low-pressure state, this pressure difference prevents the fluid flowing in from the third connecting port 313 from flowing to the sixth connecting port 316 through the second one-way valve 20.
[0057] When the first valve component 100 is connected to the first port 301, the second port 302 and the third port 303, and the second valve component 200 is connected to the fourth port 304 and the fifth port 305, the valve assembly 1 is in the second working mode. At this time, the low-temperature and low-pressure fluid flowing out of the external heat exchanger can flow into the valve assembly 1 through the first connecting port 311, and flow out of the valve assembly 1 through the second port 302, the first port 301 and the second connecting port 312 in sequence; the higher-temperature and high-pressure fluid flowing out of the condenser can flow into the valve assembly 1 through the fifth connecting port 315, and flow out of the valve assembly 1 through the fourth port 304, the fifth port 305 and the fourth connecting port 314 in sequence; the low-temperature and low-pressure fluid flowing out of the internal heat exchanger can flow into the valve assembly 1 through the third connecting port 313, and can flow out of the valve assembly 1 through two branches, the first branch passes through the second one-way valve 20, the sixth connecting port 316 and the expansion valve 400 in sequence, and the second branch passes through the third port 303, the first port 301 and the second connecting port 312 in sequence. It should be noted that, in this working mode, there is a pressure difference between the fluids on both sides of the first one-way valve 10 , so that the fluid flowing in from the first communication port 311 will not flow to the fourth communication port 314 through the first one-way valve 10 .
[0058] When the first valve member 100 is connected to the first port 301, the second port 302 and the third port 303, and the second valve member 200 is connected to the fourth port 304, the fifth port 305 and the sixth port 306, the valve assembly 1 is in the third working mode. At this time, the low-temperature and low-pressure fluid flowing out of the external heat exchanger can flow into the valve assembly 1 through the first connecting port 311, and flow out of the valve assembly 1 through the second port 302, the first port 301 and the second connecting port 312 in sequence; the higher-temperature and high-pressure fluid flowing out of the condenser can flow out of the valve assembly 1 through the first connecting port 313. The five connecting ports 315 flow into the valve assembly 1, and flow out of the valve assembly 1 through two branches respectively, the first branch sequentially passes through the fourth port 304, the fifth port 305 and the fourth connecting port 314, and the second branch sequentially passes through the fourth port 304, the sixth port 306, the sixth connecting port 316 and the expansion valve 400; the low-temperature and low-pressure fluid flowing out of the internal heat exchanger can flow into the valve assembly 1 through the third connecting port 313, and sequentially pass through the third port 303, the first port 301 and the second connecting port 312 and flow out of the valve assembly 1. It should be noted that in this working mode, there is a pressure difference between the fluids on both sides of the first and second one-way valves 10 and 20, so that the fluid flowing in from the first connecting port 311 will not flow to the fourth connecting port 314 through the first one-way valve 10, and the fluid flowing in from the third connecting port 313 will not flow to the sixth connecting port 316 through the second one-way valve 20.
[0059] When the first valve component 100 is connected to the first port 301 and the second port 302, and the second valve component 200 is connected to the fourth port 304 and the fifth port 305, the valve assembly 1 is in the fourth working mode. At this time: the low-temperature and low-pressure fluid flowing out of the external heat exchanger can flow into the valve assembly 1 through the first connecting port 311, and flow out of the valve assembly 1 through the second port 302, the first port 301 and the second connecting port 312 in sequence; the higher temperature and high-pressure fluid flowing out of the condenser can flow into the valve assembly 1 through the fifth connecting port 315, and flow out of the valve assembly 1 through the fourth port 304, the fifth port 305 and the fourth connecting port 314 in sequence; the low-temperature and low-pressure fluid flowing out of the internal heat exchanger can flow into the valve assembly 1 through the third connecting port 313, and flow out of the valve assembly 1 through the second one-way valve 20, the sixth connecting port 316 and the expansion valve 400 in sequence. It should be noted that, in this working mode, there is a pressure difference between the fluids on both sides of the first one-way valve 10 , so that the fluid flowing in from the first communication port 311 will not flow to the fourth communication port 314 through the first one-way valve 10 .
[0060] It can be seen that the present disclosure can realize the switching between the working modes of the valve assembly 1 through the communication states of different valve ports of the first valve component 100 and the second valve component 200.
[0061] The valve assembly of the present disclosure integrates multiple valve components through a valve block, thereby improving the compactness and integration of the valve assembly. Moreover, by arranging the first port, the second port and the third port on the bottom wall of the first receiving chamber, and / or the fourth port, the fifth port and the sixth port on the bottom wall of the second receiving chamber, the valve block can make the first valve component and / or the second valve component matched with the above ports be set as a butterfly valve, which can effectively reduce the height of the valve assembly compared to the ball valve, further improve the integration and reduce the occupied space. In addition, the valve block can be set as an integrated structure, which can further improve the integration, and the structure is simple and easy to install.
[0062] The present disclosure also provides a thermal management system, which includes the aforementioned valve assembly.
[0063] The above describes exemplary implementations of the valve assembly and thermal management system provided by the present disclosure with reference to preferred embodiments. However, it can be understood by those skilled in the art that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above-mentioned specific embodiments, and various technical features and structures proposed in the present disclosure can be combined in various ways without exceeding the protection scope of the present disclosure, which is determined by the attached claims.
