[0063] The following further describes this application in conjunction with the accompanying drawings and specific implementation modes:

[0064] First, for the convenience of description, it should be noted here that: the thick dashed line in the accompanying drawings is the flow path of the working medium in the first flow channel, and the thick solid line in the accompanying drawings is the flow path of the working medium in the second flow channel.

[0065] See ​ , ​ and ​ are schematic diagrams of the structure of the first implementation mode of the integrated component in this application; the following will introduce the first implementation mode of the integrated component in this application in detail.

[0066] See ​ , the integrated component 100 includes a valve body 3, a first valve component 1 and a second valve component 2. The first valve component 1 and the second valve component 2 are respectively fixedly connected to the valve body 3; the integrated component 100 further includes a first flow channel 31 and a second flow channel 32. The flow of the working medium in the first flow channel 31 and the flow of the working medium in the second flow channel 32 do not interfere with each other. The working medium in the first flow channel 31 and the working medium in the second flow channel 32 flow independently. Here, "do not interfere" means that the working medium in the first flow channel 31 and the working medium in the second flow channel 32 will not have the phenomenon of cross-flow. The first valve component 1 can throttle the working medium in the first flow channel 31, and the second valve component 2 can adjust the outflow pressure of the working medium in the second flow channel 32; through the above structure, the first valve component 1 and the second valve component 2 are integrally assembled together through the valve body 3, so the structure is compact and it is beneficial to simplify the system structure.

[0067] The following will introduce the first valve component of the integrated component in the first implementation mode in detail. See ​ , the integrated component 100 includes a first valve port 101. In this embodiment, the first valve port 101 is formed on the valve body 3. Of course, a part with the first valve port 101 can also be separately provided, and then the part with the first valve port 101 is assembled with the valve body 3; see ​, the first valve assembly 1 includes a first valve core 11 and a first driving part 12. The first driving part 12 can make the first valve core 11 move towards or away from the first valve port 101. Specifically, when the first valve core 11 moves closer to or away from the first valve port 101, the flow cross-sectional area of the working medium at the first valve port 101 changes. That is to say, the opening degree of the first valve port 101 changes. When the first valve core 11 moves towards the first valve port 101, the flow cross-sectional area of the working medium at the first valve port 101 becomes smaller, thereby enabling the working medium to form a throttle at the first valve port 101.

[0068] See ​ , in this embodiment, the first valve core 11 is spherical; the first driving part 12 includes an air box head 121 and a transmission rod 122. The air box head 121 is located on one side of the transmission rod 122, and the first valve core 11 is located on the other side of the transmission rod 122. The first valve core 11 is in contact with the transmission rod 122; see ​ and ​ , the air box head 121 includes a temperature sensing bulb 1211 and a transmission piece 1222. The transmission piece 1222 is connected to the transmission rod 122. The temperature sensing bulb 1211 is used to sense the temperature of the working medium at the outlet of the evaporator or heat exchanger in the system. The temperature sensing bulb 1211 will exert different forces on the transmission piece 1222 according to different temperatures of the working medium. Since the transmission piece 1222 is connected to the transmission rod 122 and the transmission rod 122 is in contact with the first valve core 11, the force exerted by the temperature sensing bulb 1211 on the transmission piece 1222 will also be transmitted to the first valve core 11 through the transmission rod 122, thereby enabling the first valve core 11 to move closer to or away from the first valve port 101. In this embodiment, the first valve assembly is used as a throttle part to throttle the working medium in the first flow channel.

[0069] The second valve assembly of the integrated component in the first embodiment will be introduced in detail below.

[0070] See ​ 、 ​ and ​ , the valve body 3 includes a ball core installation cavity 30, and the second valve assembly 2 includes a ball core 21. The ball core 21 is located in the ball core installation cavity 30. The ball core 21 includes a communication channel 211, and the communication channel 211 can communicate the working media on both sides of the ball core 21. In this embodiment, the communication channel 211 forms part of the second flow channel 32; see ​, the second valve assembly 2 further includes a second driving part 22. The second driving part 22 can drive the ball core 21 to rotate. During the rotation of the ball core 21, the flow cross-sectional area of the working medium at the outlet and / or inlet of the communication channel 211 will change. By changing the flow cross-sectional area of the working medium at the outlet and / or inlet of the communication channel 211, the outflow pressure of the working medium in the second flow channel 32 can be adjusted; in this embodiment, the second valve assembly 2 is equivalent to a pressure regulating part.

[0071] See ​ and ​ , in this embodiment, the second driving part 22 includes a motor part 221 and a connecting rod 222. The motor part 221 is in transmission connection with the connecting rod 222. Specifically, the motor part 221 and the connecting rod 222 are in transmission connection through gear transmission. Here, the "gear transmission" can be a single-stage transmission, or a two-stage or more than two-stage transmission mode. Of course, the motor part 221 and the connecting rod 222 can also be in transmission connection through a direct transmission method; see ​ and ​ , in this embodiment, the connecting rod 222 is in a limiting connection with the ball core 21. Here, the "limiting connection" includes a fixed connection, a radial limiting connection, and an axial limiting connection. Of course, the connecting rod 222 and the ball core 21 can also be integrally provided. Here, the "integrally provided" means that the connecting rod 222 and the ball core 21 are processed into a whole to form a single component; in this embodiment, since the motor part 221 is in transmission connection with the connecting rod 222 and the connecting rod 222 is in a limiting connection with the ball core 21, the motor part 221 can indirectly drive the ball core 21 to rotate. In addition, see ​ , in this embodiment, the central axis of the connecting rod 222 of the second valve assembly 2 is perpendicularly arranged with respect to the central axis of the first valve core 11 of the first valve assembly 1. Specifically, the central axis of the connecting rod 222 of the second valve assembly 2 is perpendicularly arranged in space with respect to the central axis of the first valve core 11 of the first valve assembly 1.

[0072] See ​ , the integrated assembly 100 further includes a cover plate 4. The cover plate 4 is fixedly connected to the valve body 3. The cover plate 4 is located on one side of the valve body 3, and the air box head 121 of the first valve assembly 1 is located on the other side of the valve body 3. The side where the cover plate 4 is located is parallel to the side where the air box head 121 in the first valve assembly 1 is located; see ​ 、 ​ , the cover plate 4 includes a communication part 41. The communication part 41 extends along the axial direction of the cover plate 4. The communication part 41 can be in communication with the outlet side of the communication channel 211 of the ball core 21. Here, the "communication" can be a direct communication or an indirect communication. In this embodiment, the cavity of the communication part 41 constitutes a part of the second flow channel 32; see ​ 、 ​ 、 ​To FIGS. 17, the cover plate 4 includes a convex portion 42 which is axially convexly provided along the cover plate 4, and the convex portion 42 extends into the connecting hole 361 of the valve body 3; thus, by providing the cover plate, it is beneficial to prevent the ball core from disengaging from the connecting hole 361; in addition, the diameter of the connecting hole 361 is larger than the diameter of the ball core 21, so that the ball core 21 can be easily loaded into the ball core installation cavity 30 from the connecting hole 361.

[0073] The valve body described above will be introduced in detail below.

[0074] See ​ 、 ​ 、 ​ 、 ​ and ​ , the integrated component 100 further includes a first port 33 and a second port 34. Specifically, the first port 33 and the second port 34 are formed on the valve body 3, and the first port 33 and the second port 34 are located on different sides of the first valve port 101 in ​ ; in this embodiment, when the first valve port 101 is opened, the first flow passage 31 can communicate the first port 33 and the second port 34. See ​ 、 ​ and ​ , in this embodiment, the first port 33 is located on the inlet side of the first flow passage 31, and the second port 34 is located on the outlet side of the first flow passage 32. Of course, the first port 33 can also be located on the outlet side of the first flow passage 31. At this time, the second port 34 is located on the inlet side of the first flow passage 31; see ​ and ​ , the first port 33 is located on the first wall surface 301 of the valve body 3, the second port 34 is located on the second wall surface 302 of the valve body 3, and the central axis of the first port 33 is perpendicularly arranged with the central axis of the second port 34. In this embodiment, the first wall surface 301 of the valve body 3 is perpendicular to the second wall surface 302 of the valve body 3.

[0075] See ​ and ​ , the integrated component 100 further includes a third port 35 and a fourth port 36. Specifically, in this embodiment, the third port 35 is formed on the valve body 3, the fourth port 36 is formed on the cover plate 4, the third port 35 and the fourth port 36 are located on different sides of the ball core 21, and the central axis of the third port 35 is perpendicularly arranged with the central axis of the fourth port 36; when the communication channel 211 of the ball core 21 is opened, the second flow passage 32 can communicate the third port 35 and the fourth port 36. In this embodiment, the third port 35 is located on the inlet side of the second flow passage 32, and the fourth port 36 is located on the outlet side of the second flow passage 32. Of course, the third port 35 can also be located on the outlet side of the second flow passage 32. At this time, the fourth port 36 is located on the inlet side of the second flow passage.

[0076] See​ and ​ In this embodiment, the side where the third port 35 is located and the side where the second port 34 is located are on the same side of the valve body 3. Specifically, both the third port 35 and the second port 34 are located on the second wall surface 302 of the valve body 3. On the valve body 3, the second port 34 and the third port 35 are not connected; in this embodiment, the wall surface on the side where the first port 33 is located is perpendicularly arranged with respect to the wall surface on the side where the second port 34 is located; refer to ​ and ​ , the valve body 3 includes a connecting channel 361. The wall surface 303 on the side where the opening of the connecting channel 361 is located is perpendicularly arranged with respect to the wall surface 301 on the side where the first port 33 is located, and the wall surface 303 on the side where the opening of the connecting channel 361 is located is perpendicularly arranged with respect to the wall surface 302 on the side where the second port 34 is located. Combining with reference to ​ , the connecting channel 361 is connected to the fourth port 36 through the communicating portion 41 of the cover plate 4.

[0077] By arranging the first port 33, the second port 34, the third port 35 and the fourth port 35 at different positions as described above, the working mediums do not interfere with each other when flowing in the first flow channel 31 and the second flow channel 32. That is to say, the working medium in the first flow channel 31 and the working medium in the second flow channel 32 flow independently, so that the phenomenon of cross-flow of the working medium does not occur in the first flow channel 31 and the second flow channel 32; in addition, combining with reference to ​ 、 ​ and ​ , in this embodiment, the side where the fourth port 36 is located is parallel to the side where the air tank head 121 in the first valve assembly is located.

[0078] Refer to ​ and ​ , in this embodiment, with the second wall surface 302 as a reference, the transmission rod 122 is on one side of the second wall surface 302. Part of the transmission rod 122 is located in the second flow channel 32, and part of the transmission rod 122 is located in the first flow channel 31. Refer to ​ , the second port 34 and the third port 35 are distributed along the axial direction parallel to the transmission rod 122, and the third port 35 is closer to the air tank head 121 than the second port 34; refer to ​ , the second flow channel 32 further includes a first flow-through portion 321 and a second flow-through portion 322. The first flow-through portion 321 is closer to the third port 35 than the second flow-through portion 322. The first flow-through portion 321 connects the third port 35 and the second flow-through portion 322. The central axis L1 of the second flow-through portion 322 is perpendicularly arranged with respect to the central axis L2 of the first flow-through portion 321. In this embodiment, the first flow-through portion 321 and the second flow-through portion 322 are formed on the valve body 3. The first flow-through portion 321 includes two flow channels with different diameters. Combining with reference to FIG. 4 and ​, part of the transmission rod 122 extends into the cavity of the first flow-through portion 321. The second flow-through portion 322 and the fourth port 36 are located on different sides of the spherical core 21. The communication channel 211 between the second flow-through portion 322 and the spherical core 21 can be connected. Specifically, in this embodiment, the inlet of the communication channel 211 between the second flow-through portion 322 and the spherical core 21 can be connected.

[0079] See ​ , in this embodiment, the central axis of the connecting channel 361 coincides with the central axis L1 of the second flow-through portion 322. Of course, the central axis of the connecting channel 361 and the central axis L1 of the second flow-through portion 322 can also be arranged in parallel; in addition, see ​ and ​ , in this embodiment, the valve body 3 is a profile part, which is convenient for processing.

[0080] See ​ , ​ is a schematic structural diagram of the second embodiment of the integrated component in the present application. The structure of the second embodiment of the integrated component in the present application will be introduced in detail below. ​ See ​ , in this embodiment, the integrated component 100a further includes a third valve assembly 5 and a third valve port 61. The first port 33 and the second port 34 of the first flow channel 31 are located on different sides of the third valve port 61; the third valve assembly 5 can cut off the working medium in the first flow channel 31 so that the working medium in the first flow channel 31 does not flow or the working medium in the first flow channel is cut off; in this embodiment, the third valve assembly 5 is equivalent to a cut-off portion.

[0082] Specifically, see ​ and ​, the third valve assembly 5 includes a third driving part 51 and a third valve core 52. Here, the third valve core 52 refers to the component that can close and open the third valve port 61, and the third driving part 51 can make the third valve core 52 move towards or away from the third valve port 61; when the third valve core 52 moves towards the third valve port 61 to a preset position, the third valve core 52 can block the third valve port 61 so as to cut off the working medium in the first flow channel 31; specifically, in this embodiment, the third driving part 51 includes a coil component 511, a moving iron core 512, a stationary iron core 513 and a pressing rod 514. The coil component 511 is sleeved on the outer periphery of the moving iron core 513. After the coil component 511 is energized, an excitation magnetic field is generated, and the moving iron core 512 acts under the action of the excitation magnetic field. The moving iron core 512 is connected to the pressing rod 514, so that the moving iron core 512 can drive the pressing rod 514 to act; when the moving iron core 512 drives the pressing rod 514 to move towards the third valve port 61 to a preset position, the pressing rod 514 can apply a positive pressure to the third valve core 52, so that the third valve core 52 can cut off the working medium in the first flow channel 31; in this embodiment, the material of the third valve core 52 is an elastic plastic material; in this embodiment, the structure and function of the third valve assembly 3 can refer to the structure and function of an electromagnetic valve. Here, the third valve assembly 2 can be a direct-acting electromagnetic valve or a pilot-operated electromagnetic valve; see ​ , in this embodiment, the central axis of the pressing rod 514 is perpendicularly arranged to the central axis of the transmission rod 122 of the first valve assembly.

[0083] See ​ , the valve body 3a includes a first accommodating part 60. The third valve core 52 is located in the cavity of the first accommodating part 60. When the third valve port 61 is opened, the third valve port 61 can communicate the second port 34 of the first flow channel 31 and the cavity of the first accommodating part 60. The bottom wall of the first accommodating part 60 has a communication hole 62. When the first valve port 101 is opened, the communication hole 62 can communicate the first valve port 101 and the cavity of the first accommodating part 60; thus, when the first valve port 101 is opened, after the working medium flows through the first port 33, passes through the first valve port 101, and then flows into the cavity of the first accommodating part 60 through the communication hole 62. At this time, if the third valve port 61 is in an open state, the working medium in the cavity of the first accommodating part 60 will flow from the third valve port 61 into the second port 34 of the first flow channel 31; at this time, if the third valve port 61 is in a closed state, the working medium in the cavity of the first accommodating part 60 will not flow, so that the working medium in the first flow channel 31 is cut off at the third valve port 61; in addition, in this embodiment, the bottom wall of the first accommodating part 60 has two communication holes 62. Of course, three or more communication holes can also be provided.

[0084] Compared with the first embodiment of the integrated component, the integrated component of this embodiment further includes a third valve component, and the function of the third valve component is equivalent to that of a solenoid valve. Compared with the first embodiment of the integrated component, the integrated component in this embodiment has more functions, a relatively high integration degree, and a more compact structure, thus simplifying the structure of the system.

When the air conditioning system operates, the refrigerant is compressed into a high-temperature and high-pressure refrigerant by the compressor 102. After passing through the condenser 101, the high-temperature and high-pressure refrigerant becomes a normal-temperature and high-pressure refrigerant. The normal-temperature and high-pressure refrigerant passes through the throttle valve 104 and enters the evaporator 103. Since the pressure of the normal-temperature and high-pressure refrigerant decreases after passing through the throttle valve 104, the refrigerant vaporizes into a low-temperature refrigerant. The low-temperature refrigerant passes through the evaporator 103, absorbs a large amount of heat, and then returns to the compressor 102 as a refrigerant.

The principle of the battery cooling system will be introduced in detail below. Refer to ​ , when the battery cooling system operates, the refrigerant is compressed into a high-temperature and high-pressure refrigerant by the compressor 102. After passing through the condenser 101, the high-temperature and high-pressure refrigerant becomes a normal-temperature and high-pressure refrigerant. The normal-temperature and high-pressure refrigerant passes through the first flow channel 31 of the integrated component 105. When flowing through the first flow channel of the integrated component 105, the pressure of the normal-temperature and high-pressure refrigerant decreases and becomes a low-temperature refrigerant after passing through the throttling part of the integrated component 105. The low-temperature refrigerant enters the heat exchanger 106 and exchanges heat with the cooling medium for cooling the battery pack in the heat exchanger 106. The refrigerant after heat exchange in the heat exchanger 106 then flows into the second flow channel 32 of the integrated component 105. After passing through the pressure regulating part of the integrated component 105, the pressure becomes smaller and becomes a low-temperature refrigerant and returns to the compressor 102.
