[0024] The features and exemplary embodiments of various aspects of this application will now be described in detail. To make the objectives, technical solutions, and advantages of the present invention clearer, the implementation of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments. In this document, relational terms such as "first" and "second" are used merely to distinguish one component from another that has the same name, and do not necessarily require or imply any such actual relationship or order between these components.

[0025] Fluid control components can be applied to thermal management systems, which can be vehicle thermal management systems, such as those for new energy vehicles. See also Figure 1-13The fluid control assembly includes a drive component 1, a valve component 2, and a flow channel management component 3. The flow channel management component 3 has a receiving cavity 301. Part of the valve component 2 is located in the receiving cavity 301, and the other part of the valve component 2 is located in the drive component 1. The valve component 2 is connected to the flow channel management component 3, and the drive component 1 is also connected to the flow channel management component 3. The drive component 1 can control the on / off state and opening degree of the valve component 2. The on / off state of the valve component 2 can change the on / off state of the flow channel 61 of the flow channel management component 3. Controlling the opening degree of the valve component 2 can achieve throttling and connection of the flow channel 61 of the flow channel management component 3. It should be noted that when the valve component 2 is fully open, the valve component 2 controls the connection of the flow channel 61 of the flow channel management component 3, and does not satisfy the throttling and connection requirement. The connection is defined to include conventional connection methods in the art, such as fixed connection, limiting connection, detachable connection, snap-fit ​​connection, sealing connection, or adhesive connection.

[0026] The flow management component 3 includes a valve body 30 and a branch pipe 60. Multiple valve bodies 30 are provided, spaced apart. One branch pipe 60 connects two adjacent valve bodies 30. The valve bodies 30 and branch pipe 60 are integrally formed. Each valve body 30 includes a receiving cavity 301, and each branch pipe 60 has a flow channel 61 connecting two adjacent receiving cavities 301. A first plane is defined, perpendicular to the axial direction of the valve bodies 30, and the projections of the branch pipes 60 onto this first plane do not overlap. Multiple valve bodies 30 (two or more) are spaced apart, with adjacent valve bodies 30 connected by branch pipes 60. The number of branch pipes 60 is related to the number of valve bodies 30 and also to the flow direction in the thermal management system. One branch pipe 60 connects two adjacent valve bodies 30. The integral formation of the branch pipe 60 and valve body 30 can be achieved through forging, casting, or a combination of the aforementioned processes and machining. In related technologies, the branch pipe section 60 and the valve body section 30 are independently set and connected together by welding or other fixing methods. Multiple valve body sections 30 are fixed on the same support plate. The technical solution of this application has a relatively simple structure. Since there is no need for further assembly between the components, the dimensional accuracy requirements of the components are low, and the manufacturing is relatively simple. In this technical solution, the number of branch pipe sections 60 can be set according to different thermal management systems. The projections of multiple branch pipe sections 60 on the first plane do not overlap, which is beneficial for demolding of the upper and lower molds during die casting, so that the flow channel management component 3 is formed in one step, improving production efficiency and saving processing costs.

[0027] To reduce the weight of the flow channel management component 3, the flow channel management component 3 includes a notch 03 located between two adjacent valve body parts 30. Specifically, the valve body part 30 in this technical solution is roughly cylindrical in shape, as the cylindrical structure can save materials to the maximum extent and reduce weight. The cylindrical structure mainly cooperates with the formation of the valve component 2, which has a receiving cavity 301. The valve component 2 forms the wall of the receiving cavity 301. The cylindrical structure makes the wall thickness of the receiving cavity 301 relatively uniform. The branch pipe part 60 connects the two adjacent valve body parts 30. The main function of the branch pipe part 60 is to form a flow channel 61, which connects to the receiving cavity 301 of the valve body part 30. The branch pipe part 60 is roughly hollow cylindrical in shape. The wall thickness of the branch pipe part 60 only needs to be able to withstand the fluid pressure. Therefore, the space between the two valve body parts 30 is partially occupied by the branch pipe part 60, and the remaining part is the notch 03. This structure can save materials and reduce the weight of the flow channel management component 3. Figure 7 As shown, along the axial direction of the valve body 30, the receiving cavity 301 includes a first sub-cavity 3011 and a second sub-cavity 3012. The first sub-cavity 3011 has an opening at the end of the valve body 30, and the second sub-cavity 3012 communicates with the first sub-cavity 3011. The first sub-cavity 3011 is closer to the valve component 2 than the second sub-cavity 3012. A portion of the flow channel 61 connects to the first sub-cavities 3011 of two adjacent valve bodies 30, and / or a portion of the flow channel 61 connects to the second sub-cavities 3012 of two adjacent valve bodies 30. That is, the flow channel 61 of the branch pipe 60 can connect to the first sub-cavities 3011 of two adjacent valve bodies 30, and can also connect to the second sub-cavities 3012 of two adjacent valve bodies 30. With this structure, the branch pipe 60 can be parallel to the first plane. After casting into a blank of the flow channel management component 3, it is beneficial to machine the flow channel 61 and the interface 04. It should be noted that each valve body 30 has a receiving cavity 301 for accommodating the valve component 2, and each valve body 30 has a receiving cavity 301 including a first sub-cavity and a second sub-cavity, which will not be labeled in the attached drawings.

[0028] Reference Figure 4 – Figure 11In this technical solution, multiple valve components 2 are provided, defining a first direction and a second direction, which intersect. Multiple valve body parts 30 are arranged in an array along the first and second directions, and branch pipe parts 60 are provided along the first and / or second directions. That is, multiple valve components 2 are arranged in rows and columns, which shortens the size in a single direction to a certain extent. Specifically, the first and second directions are arranged perpendicularly, and each valve body part 30 is arranged in two rows, with four valve body parts 30 in each row; the valve body parts 30 in the first row include a first valve body part 31, a second valve body part 32, a third valve body part 33, and a fourth valve body part 34, and the valve body parts 30 in the second row include a fifth valve body part 35, a sixth valve body part 36, a seventh valve body part 37, and an eighth valve body part 38. To make the flow channel management component 3 more compact, the centers of the receiving cavities 301 of each row of valve components 2 are approximately on a straight line. Each row is provided with multiple branch pipe sections 60. For example, in this technical solution, each row includes 4 valve body sections 30. The branch pipe sections 60 connect adjacent valve body sections 30. Therefore, 3 branch pipe sections 60 are provided in the first row and 2 branch pipe sections 60 are provided in the second row. According to the system requirements, the sixth valve component 262 and the seventh valve component 272 are not connected by flow channels 61, so no branch pipe section 60 is provided. The branch pipe sections 60 in each row are arranged along the first direction. The branch pipe section 60 is provided between the two valve body sections 30 in each column. In this embodiment, the branch pipe section 60 is provided between the third valve body section 33 and the seventh valve body section 37, and between the fourth valve body section 34 and the eighth valve body section 38. The branch pipe section 60 is arranged along the second direction. In this design, the branch pipe 60 is arranged along the first direction or the second direction, which can shorten the length of the branch pipe 60 within a limited space, which is beneficial to the compact structure of the flow channel management component 3 and reduces the flow resistance of the flow channel 61.

[0029] The flow channel management component 3 also includes an interface 04, at least one interface 04 being arranged radially along the valve body portion 30, and / or at least one interface 04 being arranged axially along the valve body portion 30. The interface 04 is used to connect the flow channel 61 of the flow channel management component 3 to other thermal management components within the system, such as condensers, evaporators, compressors, and receivers. In some technical solutions, the flow channel management component 3 has an interface portion 40, which is integrally formed with the valve body portion 30. The interface portion 40 protrudes outward along the outer wall of the valve body portion 30, and at least one interface 04 is located in the interface portion 40. The interface portion 40 has a channel 401 communicating between the interface 04 and the receiving cavity 301. Specifically, in this technical solution, the valve body 30 is generally cylindrical, and the interface 40 extends outward along the outer wall of the valve body 30 to form a protrusion. Along the radial direction of the valve body 30, the interface 40 has at least a partially planar structure, on which an interface 04 is formed. The channel 401 of the interface 40 connects the interface 04 and the receiving cavity 301. The interface 04 and the channel 401 are coaxially arranged, which is beneficial for machining after casting. It should be noted that coaxiality here refers to allowing certain machining tolerances, not absolute coaxiality. The interface 40 is formed on the outer side of the valve body 30 and is located on the outer periphery of the flow channel management component 3. Multiple interface 40s can be provided depending on the system, such as... Figure 4-5 As shown, in this embodiment, interface portions 40 are formed on the first valve component 21, the fourth valve component 24, the fifth valve component 25, the sixth valve component 26, the seventh valve component 27, and the eighth valve component 28. To improve the connection strength between the valve components 2, the interface portions 40 formed on adjacent valve components 2 can be connected as a single unit. In other embodiments, along the axial direction of the valve body portion 30, at least one interface 04 is located on the bottom wall of the valve body portion 30, and the interface 04 communicates with the receiving cavity 301. Here, "connection" means that the interface 04 can be directly connected to the receiving cavity 301, that is, the projections of the interface 04 and the receiving cavity 301 on the first plane at least partially overlap. It can also mean that the interface 04 is indirectly connected to the receiving cavity 301, that is, the interface 04 is connected to the receiving cavity 301 through the channel 401. For example, taking the seventh valve body 37 as an example, the interface 04 is connected to the first sub-cavity of the seventh valve body 37, which can reduce the length of the flow channel 61 to a certain extent. An interface 40 is formed on the seventh valve body 37, and the interface 40 is also provided with the interface 04. This interface 04 is connected to the first sub-cavity of the seventh valve body 37. Multiple loops are arranged in parallel on the same valve component 2. Some interfaces 04 are located at the bottom of the valve body 30, which reduces the volume of the interface 40 to a certain extent and is conducive to the miniaturization of the flow channel management component 3.

[0030] The valve component 2 includes a receiving cavity 301. In this embodiment, the receiving cavity 301 is a combination of multiple cylindrical cavities of different diameters. The receiving cavity 301 has an opening on the top side of the valve body 30. A portion of the valve component 2 is installed in the receiving cavity 301 through the opening. The diameter of the cylindrical cavities in the receiving cavity 301 gradually decreases along the direction away from the top side. The diameter of one or more cylindrical cavities closest to the top side is basically the same as or slightly larger than the diameter of the mounting portion of the valve component 2, so as to meet the assembly requirements, sealing requirements, or welding requirements when the valve component 2 is installed in the receiving cavity 301. Each valve component 2 includes a receiving cavity 301, and the receiving cavity 301 includes a first sub-cavity 3011 and a second sub-cavity 3012. In this embodiment, the diameter of the first sub-cavity 3011 is larger than the diameter of the second sub-cavity 3012. That is, the valve component 2 and the second sub-cavity 3012 are sealed together by a sealing element, and the valve component 2 and the first sub-cavity 3011 are clearance-fitted. This is beneficial for the assembly of the valve component 2 and the valve body 30, and also for the passage of fluid.

[0031] The flow channel management component 3 also includes a mating part 70, which is integrally formed with the interface part 40 and the valve body part 30. The mating part 70 protrudes along the outer wall of the valve body part 30 in a direction away from the center of the valve body part 30. In other technical solutions, the mating part 70 is disposed on the interface part 40, located in the planar structure of the interface part 40, near the interface 04, or along the axial direction of the valve component 2, the mating part 70 protrudes along the end face of the interface part 40. The drive component 1 is connected to the flow channel management component 3 through the mating part 70, and the external device in the thermal management system is connected to the fluid control component through the mating part 70. In this embodiment, the mating part 70 is provided with a threaded hole, and the drive component 1 is threadedly connected to the flow channel management component 3, and the external device in the thermal management system is threadedly connected to the flow channel management component 3.

[0032] The valve body 30 includes a connecting port 302 located on the wall forming the receiving cavity 301. The connecting port 302 includes a first connecting port 3021 and a second connecting port 3022. The first connecting port 3021 is formed on the side wall of the first sub-cavity, and the second connecting port 3022 is formed on the bottom wall of the second sub-cavity. Part of the first connecting port 3021 connects the channel 401 and the first sub-cavity, and part of the first connecting port 3021 connects the flow channel 61 and the first sub-cavity. Part of the second connecting port 3022 connects the channel 401 and the second sub-cavity, and part of the second connecting port 3022 connects the flow channel 61 and the second sub-cavity. The number and position of the connecting ports 302 on each valve component 2 determine the direction of the fluid. The valve component 2 can control the flow and cut-off of the fluid from the first connecting port 3021 to the second connecting port 3022, or adjust the flow rate. The fluid can also pass through the first connecting port 3021 on the valve component 2 and flow to the first sub-cavity of the adjacent valve body 30.

[0033] Specifically, at least one valve body portion 30 has two first communication ports 3021 and second communication ports 3022. One first communication port 3021 communicates with a channel 401, and the other first communication port 3021 communicates with a first sub-cavity of an adjacent valve body portion 30. The second communication port 3022 communicates with another channel 401. Figure 6-7 As shown, the interface portion 40 formed in the first valve component 21 has two interfaces 04, namely the first interface 41 and the second interface 42. The first interface 41 is connected to the first sub-cavity of the first valve component 21, and the second interface 42 is connected to the second sub-cavity of the first valve component 21. The first sub-cavity of the first valve component 21 and the second sub-cavity of the second valve component 22 are connected through the flow channel 61 of the branch pipe portion 60. The fluid enters the first valve body portion 31 from the first interface 41. The fluid can selectively flow through the valve port of the first valve component 21 and flow out from the second interface 42, or when the first valve component 21 is in a closed state, the fluid passes through the first sub-cavity of the first valve body portion 31 and enters the first sub-cavity of the second valve body portion 32 from the flow channel 61 of the branch pipe portion 60.

[0034] And / or, at least one valve body portion 30 has a first communication port 3021 and a second communication port 3022. The first communication port 3021 communicates with the first sub-cavity of its adjacent valve body portion 30, and the second communication port 3022 communicates with the second sub-cavity of its adjacent other valve body portion 30 or with the interface 4. For example, the first sub-cavity of the second valve component 22 communicates with the first sub-cavity of the first valve component 21, that is, the second valve component 22 is indirectly connected to the first interface 41. The second sub-cavity of the second valve component 22 communicates with the second sub-cavity of the third valve component 23 and with the third interface 43 formed on the fourth valve component 24. That is, the second sub-cavity of the second valve component 22, the second sub-cavity of the third valve component 23, and the second sub-cavity of the fourth valve component 24 are all connected to the third interface 43. The branch pipe portion 60 connecting the second valve component 22 and the third valve component 23 is on the same axis, and the flow channel 61, the channel 401, and the third interface 43 are coaxially arranged, which is beneficial for machining. Alternatively, the third valve body 33 may have a first communication port 3021. The first sub-cavity of the third valve body 33 and the first sub-cavity of the seventh valve body 37 are connected through the flow channel 61 of the branch pipe 60. The seventh valve body 37 has a fourth interface 44. The aforementioned flow channel 61, channel 401, and fourth interface 44 are coaxially arranged along the second direction. The branch pipe 60 is arranged along the first direction and / or the second direction to ensure that the connection distance is the shortest straight-line distance. In this technical solution, adjacent valve body parts 30 are connected by the branch pipe 60, and communication between different receiving cavities 301 is achieved through the flow channel 61. The valve component 2 and the branch pipe 60 can realize the on / off relationship between different flow channels 61 and channels 401 in the entire flow channel management component 3, satisfying the application of multiple working modes of the thermal management system.

[0035] The flow channel management component 3 of this application includes a first interface 41 and a second interface 42. The first interface 41 and the second interface 42 have openings in the interface portion 40 connected to the first valve body portion 31. The first interface 41 and the second interface 42 are arranged side by side. The third interface 43 has an opening in the interface portion 40 connected to the fourth valve body portion 34. The interface portion 40 connected to the fifth valve body portion 35 includes an eighth interface 48 and a ninth interface 49. The eighth interface 48 and the ninth interface 49 are located on different sides of the interface portion 40 connected to the fifth valve body portion 35. The interface portion 40 connected to the sixth valve body portion 36 includes a tenth interface 50. The interface portion 40 connected to the seventh valve body portion 37 includes a fourth interface 44. The interface portion 40 connected to the eighth valve body portion 38 includes a fifth interface 45 and a sixth interface 46. The fifth interface 45 and the sixth interface 46 are located on different sides of the interface portion 40 connected to the fifth valve body portion 35. The ninth interface 49, the tenth interface 50, the fourth interface 44, and the fifth interface 45 are located on the same side of the flow channel management component 3. The seventh interface 47 is located on the bottom wall of the seventh valve body 37. In this embodiment, the seventh interface 47 has an opening on the bottom surface at the connection position between the interface part 40 and the seventh valve body 37.

[0036] In this technical solution, the first sub-cavity of the first valve body 31 is connected to the first interface 41 and the first sub-cavity of the second valve body 32; the second sub-cavity of the first valve body 31 is connected to the second interface 42; the third interface 43 is connected to the second sub-cavity of the second valve body 32, the second sub-cavity of the third valve body 33, and the second sub-cavity of the fourth valve body 34; the fourth interface 44, the first sub-cavity of the third valve body 33, and the first sub-cavity of the seventh valve body 37 are connected; the fifth interface 45, the first sub-cavity of the fourth valve body 34, and the first sub-cavity of the eighth valve body 38 are connected; the sixth interface 46 is connected to the second sub-cavity of the seventh valve body 37 and the second sub-cavity of the eighth valve body 38; the seventh interface 47 is connected to the first sub-cavity of the seventh valve body 37; the eighth interface 48 is connected to the first sub-cavity of the fifth valve body 35 and the first sub-cavity of the sixth valve body 36; the ninth interface 49 is connected to the second sub-cavity of the fifth valve body 35; and the tenth interface 50 is connected to the second sub-cavity of the sixth valve body 36.

[0037] Figure 12-13The diagram illustrates an embodiment of a fluid control component applied to a thermal management system. In this embodiment, the thermal management system includes a compressor 201, a gas-liquid separator 202, a first heat exchanger 203, a second heat exchanger 204, a third heat exchanger 205, and a fourth heat exchanger 206. The working fluid in all heat exchangers is refrigerant, although some heat exchangers may include another working fluid, such as coolant. The coolant and refrigerant can exchange heat within the heat exchangers. It should be noted that in this embodiment, the gas-liquid separator 202 has a dual-channel design. One end of the first flow channel 2021 is connected to the refrigerant flow channel of the third heat exchanger 205, and the other end is connected to the ninth interface 49. One end of the second flow channel 2022 is connected to the inlet of the compressor 201, and the other end is connected to the fourth interface 44. The refrigerant flowing between the first flow channel 2021 and the second flow channel 2022 can exchange heat; in other words, the gas-liquid separator 202 has an intermediate heat exchange function. The connection relationship between the interface 04 of the fluid control component and the thermal management system is as follows: Figure 13 As shown, the outlet of compressor 201 is connected to the first interface 41, one end of the refrigerant flow channel of the third heat exchanger 205 is connected to one end of the first flow channel 2021 of gas-liquid separator 202, the other end of the refrigerant flow channel of the third heat exchanger 205 is connected to the third interface 43, the refrigerant flow channels of the first heat exchanger 203 are connected to the second interface 42 and the fifth interface 45 respectively, the refrigerant flow channels of the second heat exchanger 204 are connected to the eighth interface 48 and the sixth interface 46 respectively, and the refrigerant flow channels of the fourth heat exchanger 206 are connected to the tenth interface 50 and the seventh interface 47 respectively.

[0038] Figure 13 This is a schematic diagram illustrating the working principle of a fluid control component according to an embodiment of this application. In this embodiment, the fluid control component is applied to a thermal management system, including but not limited to the following three working modes:

[0039] First operating mode: First valve component 21 is closed, third valve component 23 and fourth valve component 24 are closed, second valve component 22 is open. The high-temperature and high-pressure gaseous working fluid (such as refrigerant) at the outlet side of compressor 201 flows from first interface 41 through the first sub-cavity of first valve body 31 to the first sub-cavity of second valve body 32, flows out from third interface 43 and enters the refrigerant flow channel 61 of third heat exchanger 205. After being cooled and dissipated by third heat exchanger 205, it becomes a higher-temperature working fluid and enters the first flow channel 2021 of gas-liquid separator 202. After being cooled and dissipated by intermediate heat exchange in gas-liquid separator 202, it flows into first interface 04. After being throttled by fifth valve component 25, it becomes a low-temperature and low-pressure gas-liquid two-phase working fluid. A portion of it flows from first interface 04 into the refrigerant flow channel 61 of second heat exchanger 204. After being evaporated and absorbed by heat by second heat exchanger 204, it becomes a lower-temperature working fluid and flows into sixth interface 46. When third valve component 23 and eighth valve component 28 are closed and seventh valve component 27 is open... When open, the lower-temperature working fluid flows from the sixth port 46 through the first sub-cavity of the eighth valve body 38 into the first sub-cavity of the seventh valve body 37, and flows out from the fourth port 44 through the seventh valve component 27; another part of the fluid is throttled again by the sixth valve component 26 and flows into the refrigerant passage of the fourth heat exchanger 206 from the first port 04. After heat exchange and evaporation with the working fluid in the coolant passage of the fourth heat exchanger 206, it becomes a lower-temperature working fluid, flows in from the seventh port 47, and merges with the lower-temperature working fluid flowing out from the fourth port 44. They flow together into the second flow passage 2022 of the gas-liquid separator 202. After gas-liquid separation by the gas-liquid separator 202, the gas phase working fluid flows back to the inlet of the compressor 201 for recirculation. It should be noted that in this working mode, the seventh valve component 27 can be closed. At this time, the low-temperature and low-pressure gas-liquid two-phase working fluid after being throttled by the fifth valve component 25 is directly throttled again by the sixth valve component 26, retaining only the working process of the other part of the fluid.

[0040] Second operating mode: With the second valve component 22 closed, the fourth valve component 24 closed, the seventh valve component 27 closed, the eighth valve component 28 open, and the third valve component 23 open, the high-temperature and high-pressure gaseous working fluid (such as refrigerant) at the outlet side of the compressor 201 flows from the first port 41 into the first sub-cavity of the first valve body 31, flows out through the first valve component 21 from the second port 42 into the refrigerant channel of the first heat exchanger 203, and after being cooled and dissipated by the first heat exchanger 203, it becomes a higher-temperature working fluid that flows from the fifth port 45 into the first sub-cavity of the eighth valve body 38, flows out from the sixth port 46 into the refrigerant channel of the second heat exchanger 204, and after being cooled and heat-exchanged again by the second heat exchanger 204, it flows in from the first port 04. A portion of it is throttled by the fifth valve component 25 and flows out from the first port 04 into the first flow channel 2021 of the gas-liquid separator 202. After intermittent heat exchange and cooling, the refrigerant enters the refrigerant channel of the third heat exchanger 205. After evaporation and heat absorption in the third heat exchanger 205, it becomes a lower-temperature working fluid and flows into the second sub-cavity of the third valve body 33 from the third port 43. The refrigerant flows in through the third valve component 23 and flows out from the fourth port 44. Another part flows into the refrigerant channel of the fourth heat exchanger 206 from the first port 04 after being throttled by the sixth valve component 26. After heat exchange and evaporation and heat absorption with the working fluid in the coolant channel of the fourth heat exchanger 206, it becomes a lower-temperature working fluid and flows in from the seventh port 47. After merging with the lower-temperature working fluid flowing out from the fourth port 44, they flow together to the gas-liquid separator 202. After gas-liquid separation by the gas-liquid separator 202, the gas phase working fluid flows back to the inlet of the compressor 201 for recirculation. It should be noted that in this working mode, the eighth valve component 28 can be fully open, or the opening degree can be adjusted according to actual use.

[0041] Third operating mode: First valve component 21 is open, second valve component 22 is closed, third valve component 23 is closed, fourth valve component 24 is open, seventh valve component 27 is closed, and eighth valve component 28 is closed. The high-temperature and high-pressure gaseous working fluid (such as refrigerant) at the outlet side of compressor 201 flows in from the first port 41, passes through the first valve component 21, flows out from the second port 42, enters the refrigerant flow channel 61 of the first heat exchanger 203, and after being cooled and dissipated by the first heat exchanger 203, it becomes a higher-temperature working fluid that passes through the first sub-cavity of the eighth valve body 38 from the fifth port 45, enters through the fourth valve component 24, flows out from the third port 43, enters the refrigerant flow channel of the third heat exchanger 205, and after being cooled and dissipated by the third heat exchanger 205, it becomes a higher-temperature working fluid that enters the gas-liquid separator. After being cooled by intermediate heat exchange in the gas-liquid separator 202, the refrigerant flows into the first flow channel 2021 of the separator 202 from the first interface 04. After being throttled by the fifth valve component 25, it becomes a low-temperature, low-pressure gas-liquid two-phase working fluid. The refrigerant cannot flow into the second heat exchanger 204 from the first interface 04 for heat exchange. At this time, the refrigerant is throttled again by the sixth valve component 26 and flows into the refrigerant channel of the fourth heat exchanger 206 from the first interface 04. After heat exchange and evaporation with the working fluid in the coolant channel of the fourth heat exchanger 206, it becomes a lower-temperature working fluid. It flows into the seventh interface 47 and flows out from the fourth interface 44 into the second flow channel 2022 of the gas-liquid separator 202. After gas-liquid separation by the gas-liquid separator 202, the gas phase working fluid flows back to the inlet of the compressor 201 for recirculation.
