Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application

[0042] The connecting piece of the present application is used for a thermal management system, especially a vehicle thermal management system, and can also be used for thermal management systems such as commercial, household, and energy storage

[0043] Embodiment 1

[0044] As Figures 1 - 4As shown, an embodiment of the present application provides a connector 10. The connector 10 can be used to install heat management components of a heat management system. The connector 10 has a flow channel, and the flow channel can communicate with the channels of the heat management components. In this embodiment, the connector 10 has a first flow channel 11 and a second flow channel 12. Both the first flow channel 11 and the second flow channel 12 are straight-through flow channels, and the first flow channel 11 and the second flow channel 12 are arranged parallel to each other. In other embodiments, the extension paths of the first flow channel 11 and the second flow channel 12 are arranged at an angle. The connector 10 includes an interface portion, and the interface portion includes a first interface portion 112, a second interface portion 113, a third interface portion 122, and a fourth interface portion 123. The first flow channel 11 is respectively communicated with the interfaces of the first interface portion 112 and the second interface portion 113, and the second flow channel 12 is respectively communicated with the interfaces of the third interface portion 122 and the fourth interface portion 123. Along the extension direction of the first flow channel 11, different multi-way valves are respectively installed at both ends of the connector 10. The first flow channel 11 can communicate with at least one channel of one multi-way valve and at least one channel of another multi-way valve. The second flow channel 12 is similar to the first flow channel 11 and is used to communicate with the channels of different multi-way valves.

[0045] As Figures 2 - 4 shown, the connector 10 includes a connecting component 20. At least a part of the first flow channel 11 is located on one side of the connecting component 20, and at least a part of the second flow channel 12 is located on the opposite side of the connecting component 20. The connecting component 20 has a first port 111 and a second port 121. The connecting component 20 has a connecting channel 21, and the connecting channel 21 communicates with the first port 111 and the second port 121. The first port 111 communicates with the first flow channel 11, and the second port 121 communicates with the second flow channel 12. In this way, the first flow channel 11 and the second flow channel 12 can be communicated with the help of the connecting channel 21.

[0046] As Figures 2 - 4 shown, the connecting channel 21 includes a main channel 211 and a branch channel 25. One end of the main channel 211 communicates with the first port 111, and the other end of the main channel 211 communicates with the second port 121. The branch channel 25 has a first port 251 and a second port 252. Both the first port 251 and the second port 252 face away from the second port 121. Both ends of the branch channel 25 communicate with one end of the main channel 211 close to the first port 111. The main channel 211 includes a mixing area 212, which is shown in Figure 3 and Figure 4 by a dashed box, and the mixing area 212 is close to the second port 252.

[0047] The connector 10 of this embodiment includes two working modes:

[0048] First working mode: The fluid in the main channel 211 flows from the first port 111 to the second port 121. Part of the fluid in the mixing zone 212 flows to the second port 121. The fluid in the branch channel 25 flows to the second port 252. The fluid in the branch channel 25 flows to the mixing zone 212. The fluid in the mixing zone 212 includes two parts of fluid flowing in opposite directions. Part of the fluid in the first flow channel 11 can flow to the second flow channel 12;

[0049] Second working mode: The fluid in the main channel 211 flows from the second port 121 to the first port 111. Part of the fluid in the mixing zone 212 flows to the first port 111. Another part of the fluid in the mixing zone 212 flows to the branch channel 25. The fluid in the branch channel 25 flows to the first port 251. The fluid in the second flow channel 12 can flow to the first flow channel 11.

[0050] Figure 3 In the figure, the flow path of the fluid flowing in from the first port 111 in the first working mode is shown by a dotted line with an arrow. For the fluid flowing in from the first port 111, part of it flows through the main channel 211 and flows out from the second port 121, and the other part flows into the branch channel 25 from the first port 251 and flows out from the second port 252 and then flows through the mixing zone 212. The fluid flowing through the mixing zone 212 includes two branches of fluid flowing in opposite directions. When the fluid flowing through the branch channel 25 flows out from the second port 252, it can give a certain resistance to the fluid flowing in the main channel 211, thereby preventing the fluid from flowing out from the second port 121.

[0051] Figure 4 In the figure, the flow path of the fluid flowing in from the second port 121 in the second working mode is shown by a dotted line with an arrow. The fluid flowing in from the second port 121 is divided in the mixing zone 212. Part of the fluid flows along the main channel 211 to the first port 111, and the other part of the fluid flows into the branch channel 25 from the second port 252 and flows out from the first port 251, and then mixes with the fluid in the main channel 211 and flows out from the first port 111. Because the two paths of fluid mix near the first port 111, even if the two paths of fluid flow in opposite directions, it will not have a great impact on the fluid flowing out from the first port 111 in the communication channel 21.

[0052] That is to say, the setting of the connecting component 20 enables the fluid flowing in from the second port 121 to flow out from the first port 111, and can prevent the fluid flowing in from the first port 111 from flowing out from the second port 121. In other words, the connecting component 20 can unidirectionally connect the second port 121 to the first port 111, or it can be said that the connecting component 20 can unidirectionally connect the second flow channel 12 to the first flow channel 11. It should be noted that the unidirectional connection in this application does not mean reverse cutoff. Unidirectional connection means that one direction can be connected, and only a small part of the fluid can be connected in the reverse direction, while the flow of most of the fluid in the reverse direction is blocked and cannot be connected. The setting of the connecting component 20 is equivalent to installing a check valve in the connecting member 10, which is beneficial to simplifying the manufacturing process and saving manufacturing costs.

[0053] Figure 2 Fig. shows a three-dimensional structural schematic diagram of the base body of the connecting member 10. The base body includes a groove, and the groove forms at least part of the flow channel. Another part of the groove forms at least part of the communication channel 21. The connecting member 10 further includes a cover plate (not shown), and the cover plate can cover the opening of the groove. The wall forming the flow channel includes the side wall of the groove and the wall of the cover plate, and the wall forming the communication channel 21 includes the wall of another part of the groove and the wall of another part of the cover plate. In a specific embodiment, the cover plate includes a mating groove, and the mating groove is correspondingly arranged with the groove and can be assembled to form a flow channel or a communication channel. In another specific embodiment, the cover plate can be a split structure, the outer shape of the cover plate matches the shape of the groove, and the split cover plates respectively cover the corresponding grooves, or one cover plate covers several grooves.

[0054] The structure of the connecting component 20 will be introduced below by taking the structure of the substrate as an example. As Figures 2 - 4As shown, the connecting component 20 includes a main body portion 27, a first portion 28, and a second portion 29. The main body portion 27 includes a first inner wall 271 and a second inner wall 272 that are oppositely arranged. Both the first inner wall 271 and the second inner wall 272 are arc-shaped surfaces. The first portion 28 is generally an arc-shaped structure. The first portion 28 has a first side wall 281 and a second side wall 282 that are arranged back to back. The walls forming the main channel 211 include at least part of the first inner wall 271 and at least part of the first side wall 281. The walls forming the branch channel 25 include at least part of the second inner wall 272 and at least part of the second side wall 282. At least part of the first side wall 281 faces the first inner wall 271, and at least part of the second side wall 282 faces the second inner wall 272. That is to say, along the radial direction of the connecting channel 21, part of the main body portion 27 is located on one side of the first portion 28, and another part of the main body portion 27 is located on the other side of the first portion 28. The first side wall 281 and the first inner wall 271 are oppositely arranged, so that the fluid flowing through the branch channel 25 forms a reflux state, thereby hindering the fluid flowing in from the first port 111. The second portion 29 is a cylindrical structure. Part of the main body portion 27 and the first portion 28 surround the second portion 29. The walls forming the branch channel 25 include at least part of the second inner wall 272, at least part of the second side wall 282, and at least part of the outer side wall of the second portion 29. The setting of the second portion 29 forms a flow guiding member for the branch channel 25, which facilitates the fluid entering from the first port 251 to flow along the side wall. Under the action of centrifugal force, the fluid flow rate is relatively fast, so that the fluid flowing out from the second port 252 has a relatively fast flow rate, which is beneficial to better hinder the fluid flowing in from the first port 111.

[0055] The connecting component 20 includes a first wall 221 and a second wall 222. Specifically, the main body portion 27 includes a first wall 221 and a second wall 222. The walls forming the first flow channel 11 include at least part of the first wall 221, and the walls forming the second flow channel 12 include at least part of the second wall 222. The first port 111 is located on the first wall 221, and the second port 121 is located on the second wall 222.

[0056] As Figure 3 shown, along the extending path direction of the branch channel 25, the radial dimension of the branch channel 25 shrinks from the first port 251 to the second port 252. Along the extending path direction of the main channel 211, the radial dimension of at least part of the main channel 211 shrinks from the second port 121 to the first port 111. The design of the reduced diameter of the branch channel 25 can accelerate the flow rate of the fluid flowing out from the second port 252 and increase the hindrance to the fluid flowing in from the first port 111. The design of the reduced diameter of the main channel 211 can accelerate the fluid flowing from the second port 121 to the first port 111, which is beneficial to the one-way connection from the second port 121 to the first port 111. It should be noted that the gradual change law of the radial dimension of the connecting channel 21 can be understood as the gradual change law of the flow cross-section of the connecting channel 21.

The fourth connection flow channel 72 is in communication with the interface of the fourth interface part 123, and the third connection flow channel 71 is in communication with the fourth valve port 42.

[0062] In this embodiment, as Figures 14 to 15 shown, the shape of the first connection part 60 is not strictly limited; for example, the shape of the first connection part 60 is generally plate-shaped; the first connection part 60 is hermetically connected to the connecting member 10 by means of screws or welding.

The second connection part 70 includes a first protrusion 73, and the second connection part 70 has a first groove 74.

[0064] As Figure 19As shown, the connector 10 includes a mounting portion 18, and the integrated device 100 includes a pump 80. In this embodiment, the number of the mounting portions 18 is three, and the corresponding number of the pumps 80 is three. At least part of the pump 80 is located in the cavity of the mounting portion 18. The pump 80 can provide power to the fluid flowing through the channel of the pump 80. The first pump 81 corresponds to the first pump mounting portion 181, the second pump 82 corresponds to the second pump mounting portion 182, and the third pump 83 corresponds to the third pump mounting portion 183. Among them, the channel of the first pump 81 is communicated with the second flow channel 12 of the connector 10.

[0065] As Figures 5 - 13 shown, the integrated device 100 includes a liquid reservoir 50. The liquid reservoir 50 includes a kettle body 51. The kettle body 51 is integrally provided with the connector 10, which can reduce the processing difficulty of the kettle body 51 and the connector 10, and strengthen the connection strength between the kettle body 51 and the connector 10. As Figure 10 shown, the kettle body 51 has a liquid storage cavity 53, and the connector 10 has an integrated flow channel 13. The wall forming the integrated flow channel 13 includes the inner wall of the connector 10. The interface portion of the connector 10 includes a fifth interface portion 133.

The medium can enter the liquid storage cavity 53 from the integrated flow channel 13, and the medium can also enter the integrated flow channel 13 from the liquid storage cavity 53. Among them, the medium can be a coolant. The liquid reservoir 50 can also be called an expansion kettle or an expansion tank. The connector 10 is also provided with another integrated flow channel 13 corresponding to the third pump 83, and the structure is similar to the above integrated flow channel 13, which will not be elaborated here. In addition, the connector 10 also includes an integrated flow channel 13 corresponding to the second multi-way valve 40. The integrated flow channel 13 corresponding to the second multi-way valve 40 can guide the fluid flowing out of the valve port of the second multi-way valve 40 to other positions of the integrated device 100 and communicate with the interfaces of the interface portions located at other positions. The setting of the integrated flow channel 13 makes the function of the connector 10 more abundant, so that the connector 10 can facilitate the installation of a multi-way valve with more valve ports.

[0066] As Figure 10 shown, the liquid reservoir 50 further includes a kettle lid 52. The kettle body 51 also has an inlet, and the inlet is communicated with the liquid storage cavity 53.

[0067] In this embodiment, the connecting member 10 includes a communicating member 20, and the structure of the communicating member 20 is similar to that in the first embodiment. In this embodiment, the connecting member 10 includes a cover plate, and the cover plate can seal the communicating channel 21. No corresponding cover plates are provided for the first flow channel 11 and the second flow channel 12. In this embodiment, the kettle body 51 and the connecting member 10 are integrally provided, and at least part of the outer side wall of the connecting member 10 can serve as the inner bottom wall of the kettle body 51. Or rather, the wall forming the liquid storage cavity 53 includes the inner wall of the kettle body 51 and the wall of the connecting member 10. The kettle body 51 can be integrally injection-molded. That is to say, the first flow channel 11 and the second flow channel 12 are formed inside the connecting member 10 integrally formed with the kettle body 51. Of course, in other embodiments, the communicating member 20 can be separately molded and then fixedly connected or limitedly connected to the connecting member 10. Or rather, the communicating member 20 can be separately molded and then fixedly connected or limitedly connected to the kettle body 51. Or rather, multiple components of the communicating member 20 can be separately molded and then cooperatively installed with other parts of the connecting member 10. That is to say, the communicating member 20 can be a split structure.

[0068] Next, on the basis of the first embodiment, the structure of the connecting member 10 will be further introduced.

[0069] In this embodiment, as Figures 11 to 12As shown, the connecting channel 21 includes a main channel 211 and a branch channel 25. The extending path of the branch channel 25 is an unclosed circular arc. The branch channel 25 has a first port 251 and a second port 252. The main channel 211 includes a first channel 23, a second channel 24, and a fourth channel 26. The first channel 23 has a fifth port 231 and a sixth port 232. The fifth port 231 is the first port 111. The second channel 24 has a third port 241 and a fourth port 242. The third port 241 is connected to the sixth port 232. The first port 251 is connected to the sixth port 232. The second port 252 is connected to the fourth port 242. The fourth channel 26 has a seventh port 261 and an eighth port 262. The seventh port 261 is connected to the fourth port 242. The eighth port 262 is the second port 121. That is to say, the sixth port 232, the first port 251, and the third port 241 are located in the diversion area, enabling the fluid flowing in from the first port 111 to be diverted here. Correspondingly, the second port 252, the fourth port 242, and the seventh port 261 are located in the mixing area 212. The fluid flowing out of the branch channel 25 and the fluid flowing through the second channel 24 can converge here. The second port 252 faces the first port 111, and the flowing direction of the fluid flowing out of the second port 252 is opposite to that of the fluid flowing into the second channel 24, causing the fluid flowing into the second channel 24 to be blocked. When the acting force of the fluid flowing out of the second port 252 on the fluid flowing through the second channel 24 is relatively large, it is difficult for the fluid flowing through the second channel 24 to flow into the fourth channel 26 through the mixing area 212. That is to say, it is unidirectionally non-connected from the first port 111 to the second port 121. Specifically, the connector 10 includes two working modes:

[0070] The first working mode: The fluid in the main channel 211 flows from the first port 111 to the second port 121. The medium enters the first channel 23, and then the medium flows out of the first channel 23. A part of the medium flowing out of the first channel 23 enters the second channel 24, and the other part enters the branch channel 25. When the medium flowing into the branch channel 25 flows out of the branch channel 25, it impacts the medium in the second channel 24 in the reverse direction, which can increase the resistance of the medium flowing out of the second channel 24 and reduce the amount of the medium flowing from the second channel 24 to the fourth channel 26.

[0071] Second working mode: The fluid in the main channel 211 flows from the second port 121 to the first port 111, the medium enters the fourth channel 26, then the medium flows out of the fourth channel 26, the medium flowing out of the fourth channel 26 enters the second channel 24, and then the medium in the second channel 24 flows into the first channel 23, and the medium entering the first channel 23 flows out of the communication channel 21; wherein, a small part of the medium flowing out of the fourth channel 26 and / or the second channel 24 will enter the branch channel 25. When the fluid flowing in the main channel 211 is not significantly blocked, it can be said that the second port 121 is unidirectionally connected to the first port 111. The second port 252 generally faces the first wall 221.

[0072] As Figure 12 shown, a first surface S is defined. The first surface S is perpendicular to the arrangement direction of the first flow channel 11 and the second flow channel 12. The wall forming the first port 111 and the wall forming the sixth port 232 at least partially coincide in the projection on the first surface S. The wall forming the first port 111 and the wall forming the first port 251 at least partially coincide in the projection on the first surface S. The wall forming the sixth port 232 and the wall forming the fourth port 242 are misaligned in the projection on the first surface S. The wall forming the sixth port 232 and the wall forming the seventh port 261 are misaligned in the projection on the first surface S. The wall forming the sixth port 232 and the wall forming the second port 252 are misaligned in the projection on the first surface S. The wall forming the second port 121 and the wall forming the first port 111 are misaligned in the projection on the first surface S. The arrangement of each port enables the fluid flowing out of the second port 252 to give greater resistance to the fluid flowing through the second channel 24, so that most of the fluid flowing into the first port 111 preferentially flows into the branch channel 25.

[0073] In this embodiment, as Figures 11 to 12 shown, consistent with Embodiment 1, the connecting component 20 includes a main body portion 27, a first portion 28 and a second portion 29. The main body portion 27 includes a first wall 221 and a second wall 222. The main body portion 27 includes a first inner wall 271 and a second inner wall 272 arranged oppositely. The first portion 28 has a first side wall 281 and a second side wall 282 arranged back to back. The first side wall 281 and a part of the first inner wall 271 form at least part of the wall of the fourth channel 26. A part of the outer side wall of the second portion 29 and a part of the first inner wall 271 form at least part of the wall of the second channel 24. Another part of the outer side wall of the second portion 29, a part of the second inner wall 272 and the second side wall 282 form at least part of the wall of the branch channel 25. The second channel 24 and the branch channel 25 are circumferentially arranged around the second portion 29; the gap between the main body portion 27, the first portion 28 and the second portion 29 forms the communication channel 21.

[0074] In this embodiment, the connecting component 20 is integrally provided with other components of the connecting member 10, which can reduce the manufacturing process of the connecting component 20 installed as a separate component in the corresponding installation cavity of the connecting member 10. The first part 28 is generally in an arc-shaped structure. The first part 28 has a first end and a second end facing away from each other. The first end of the first part 28 is connected to the second wall 222, and the second end of the first part 28 is located between the first wall 221 and the second wall 222; the wall of the main body part 27 opposite to the first side wall 281 is the first inner wall 271, and the first inner wall 271 is connected to the first wall 221. The first side wall 281 of the first part 28 is an arc surface, and the first inner wall 271 is an arc surface; along the extension path of the fourth channel 26, the radial dimension of the fourth channel 26 gradually decreases from the second port 121 to the seventh port 261. The outer peripheral wall of the second part 29 is a continuous curved surface, the second side wall 282 is an arc surface, and the gap between the second side wall 282 and a part of the outer peripheral wall of the second part 29 forms a part of the branch channel 25. The main body part 27 further includes a second inner wall 272, the second inner wall 272 is connected to the second side wall 282, the second inner wall 272 is an arc surface, and the gap between the second inner wall 272 and a part of the outer peripheral wall of the second part 29 forms a part of the branch channel 25. The main body part 27 further includes a third inner wall 273, the third inner wall 273 is connected to the first inner wall 271, and the gap between the third inner wall 273 and a part of the outer peripheral wall of the second part 29 forms at least a part of the second channel 24. The main body further includes a fourth inner wall 274 and a fifth inner wall 275. The fourth inner wall 274 is connected to the second inner wall 272, the fifth inner wall 275 is connected to the fourth inner wall 274, and the gap between the fourth inner wall 274 and the fifth inner wall 275 forms the first channel 23. Perpendicular to the direction of the first plane S, the wall forming the sixth port 232 and the second part 29 at least partially overlap in the projection on the first plane S, so that when the medium flows out of the first channel 23, a part of the medium flows into the second channel 24, and another part of the medium flows into the branch channel 25.
