In traditional fluid management components, the pump component adopts a flow mode of end face inlet and side outlet, and the structure of the impeller cavity cover is relatively complex. At the same time, the flow channel is arranged in the installation part of the flow channel component, which makes the molding of the flow channel plate difficult. Utility Model Content

The pump inlet flow channel connects to the first port, and the pump outlet flow channel connects to the second port. Compared to traditional flow channel assemblies, where the first and second ports are not on the same side, the flow channel assembly requires a curved flow channel connection during pump outlet flow channel processing, making the flow channel assembly difficult to form. In this application, the pump inlet and pump outlet flow channels of the flow channel assembly are located on the same side, simplifying the forming difficulty of the flow channel assembly, further simplifying the process flow, thereby reducing the overall process difficulty of the fluid management component, and thus reducing costs to a certain extent.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of this utility model and are not intended to limit its scope.

[0031] This application provides a fluid management component 100, which can be applied to a thermal management system, and the thermal management system can be used in household air conditioners, automotive air conditioners, and energy storage systems.

[0032] refer to Figures 1 to 18As shown, the fluid management assembly 100 includes a flow channel assembly 1 and a pump assembly 2. The flow channel assembly 1 has a receiving cavity 101, or in other words, the flow channel assembly 1 includes a receiving cavity 101 with an opening. The pump assembly 2 is at least partially located in the receiving cavity 101. The pump assembly 2 is fixedly connected to or limited by the flow channel assembly 1, for example, by welding, bonding, fasteners, threaded connection, or snap-fit ​​limiting. In this application, the pump assembly 2 and the flow channel assembly 1 are fixed by a threaded connection. The threaded connection makes the pump assembly 2 easy to disassemble, making subsequent maintenance more convenient and further reducing the replacement cost of parts. The flow channel assembly 1 has a pump inlet flow channel 102 and a pump outlet flow channel 103. The pump assembly 2 has a first port 201 and a second port 202. The openings of the first port 201 and the second port 202 are arranged along the thickness direction of the flow channel assembly 1. The openings of the pump inlet flow channel 102 and the pump outlet flow channel 103 are arranged along the thickness direction of the flow channel assembly 1. A first plane is defined and is perpendicular to the thickness direction of the flow channel assembly 1. The projection of the first port 201 on the first plane coincides with the projection of the wall forming the opening of the pump inlet flow channel 102 on the first plane. The projection of the second port 202 on the first plane coincides with the projection of the wall forming the opening of the pump outlet flow channel 103 on the first plane. The pump inlet flow channel 102 is connected to the first port 201, and the pump outlet flow channel 103 is connected to the second port 202. The openings of the first port 201 and the second port 202 are positioned toward the end of the pump inlet channel 102, indicating that the first port 201 and the second port 202 are located at the same end. Similarly, the pump inlet channel 102 and the pump outlet channel 103 of the channel assembly 1 that cooperate with it are also at the same end. In contrast to traditional pump components 2, where the first port 201 and the second port 202 are not on the same side, and the pump inlet flow channel 102 and the pump outlet flow channel 103 of the corresponding flow channel component 1 are also not on the same side, the production of the pump outlet flow channel 103 of the flow channel component 1 involves a curved flow channel, making the molding of the flow channel component 1 difficult. In this application, the pump inlet flow channel 102 and the pump outlet flow channel 103 of the flow channel component 1 are located at the same end, simplifying the structure of the flow channel component 1. This reduces the manufacturing difficulty of the flow channel component 1 and further reduces the molding difficulty of the flow channel component 1. At the same time, it reduces the overall manufacturing difficulty of the fluid management component 100 to a certain extent, thereby reducing the cost to a certain extent. In other words, with the first port 201 and the second port 202 located at the same end, the pump outlet flow channel 103 can be designed with flow channels in any direction according to requirements, without being limited to the design along the direction of the pump outlet, thus simplifying the process design to a certain extent. The first port 201 and the second port 202 of the pump assembly 2 are on the same end face, which also helps to make the structure of the pump assembly 2 more compact, so that the axial height dimension of the pump assembly 2 can be reduced. The axial direction of the pump assembly 2 is consistent with the thickness direction of the flow channel assembly 1, and the pump assembly 2 saves space to a certain extent when it is assembled with the flow channel assembly 1.

[0033] Further reference Figures 3 to 18 The pump assembly 2 includes a first housing 21, an isolation sleeve 22, a rotor assembly 23, a pump shaft 24, and a second housing 25. The isolation sleeve 22 and the pump shaft 24 are integrally formed, with the pump shaft 24 as an insert integrally molded with the isolation sleeve 22. This eliminates gaps in traditional assembly, which helps to improve pressure resistance and withstand the impact of the medium, while also extending service life. It also simplifies the assembly process and reduces labor and post-processing costs. Of course, in other specific embodiments, the isolation sleeve 22 and the pump shaft 24 can also be separate structures, which helps to improve the utilization rate of parts, facilitates the later upgrading and replacement of parts, and further facilitates later maintenance. At the same time, disassembling the parts also helps to reduce the processing difficulty of individual parts, further reducing processing costs to a certain extent. The isolation sleeve 22 is located away from the flow channel assembly 1 relative to the first housing 21. The cross-sectional shape of the isolation sleeve 22 along the axial direction of the pump assembly 2 is T-shaped, with a cavity in its middle, namely, the isolation sleeve 22 has a first cavity 222. The opening of the first cavity 222 faces the second opening 202. At least a portion of the rotor assembly 23 is located in the first cavity 222. The cross-sectional shape of the rotor assembly 23 along the axial direction of the pump assembly 2 is T-shaped, with a through hole in its middle. The rotor assembly 23 is sleeved on the pump shaft 24, and the rotor assembly 23 can rotate under the restriction of the pump shaft 24. The isolation sleeve 22 is fixedly connected or limited to the second housing 25, which can be fixed by welding, bonding, fasteners, or snap-fit ​​limiting, etc. The second housing 25 is located away from the first housing 21 and away from the flow channel assembly 1. The second housing 25 is fixedly connected to or limited by the first housing 21, which can be fixed by welding, bonding, fasteners, or snap-fit. In this application, the second housing 25 is fixed to the first housing 21 by welding, which helps to ensure the sealing between the first housing 21 and the second housing 25, thereby protecting the internal components. At the same time, it saves materials to a certain extent, as no additional connectors are needed, which helps to reduce material costs. It also helps to reduce the overall weight of the pump assembly 2. Specifically, as shown in the example... Figures 9 to 11 and Figure 17As shown, the first housing 21 includes a limiting protrusion 216, which protrudes from the end of the first housing 21 away from the flow channel assembly 1 and is arranged circumferentially along the first housing 21. The second housing 25 includes a limiting groove 251, the opening of which faces the first housing 21. The limiting protrusion 216 engages with the limiting groove 251. This method facilitates assembly positioning and simplifies the installation process. At least a portion of the first housing 21 is located in the receiving cavity 101. The first housing 21 is fixedly connected to or limited by the flow channel assembly 1, which can be fixed by welding, bonding, fasteners, or snap-fit. In this application, a portion of the first housing 21 has threads, and the first housing 21 is fixed to the flow channel assembly 1 by a threaded connection. This reduces the number of fasteners, thereby reducing material costs and the overall weight of the structure to a certain extent, and also makes the structure of the pump assembly 2 more compact.

[0034] Pump assembly 2 has an impeller cavity 203. The wall portion forming the impeller cavity 203 is located in the first housing 21 and partly in the isolation sleeve 22. The first housing 21 includes an impeller cover portion 211, a volute portion 212, and a mounting portion 213. The impeller cover portion 211, the volute portion 212, and the mounting portion 213 are integral structures, that is, the impeller cover portion 211, the volute portion 212, and the mounting portion 213 are integrally injection molded. The integral injection molding has no seams or connection points, which helps to strengthen the strength of the first housing 21 and improve the overall durability of the first housing 21. The volute portion 212 is located on the periphery of the impeller cover portion 211, and the mounting portion 213 is located away from the impeller cover portion 211 relative to the volute portion 212. The mounting portion 213 is located on the peripheral wall of the first housing 21. At the same time, there is a groove between the mounting portion 213 and the volute portion 212. The groove helps to reduce the overall weight of the pump assembly 2. The wall forming the receiving cavity 101 includes a first wall portion 11, and a mounting portion 213 has threads. The mounting portion 213 is threadedly connected to the first wall portion 11, which makes subsequent maintenance more convenient and further reduces the replacement cost of parts. Compared with the traditional installation method, the use of bolts, pre-embedded nuts and reinforcing fasteners is eliminated. At the same time, the design of fasteners is eliminated, and to a certain extent, there is no need to consider the accuracy of the holes and the dimensional tolerance requirements of the pre-embedded nuts, which simplifies the processing technology and helps to reduce processing costs.

[0035] Furthermore, the first port 201 is located in the impeller cover portion 211, and the second port 202 is located in the volute portion 212. Alternatively, it can be said that the wall connection mounting portion 213 forming the second port 202 is connected to the impeller cover portion 211. The impeller cavity 203 connects the first port 201 and the second port 202. The first port 201 connects the impeller cavity 203 and the pump inlet flow channel 102. The second port 202 connects the impeller cavity 203 and the pump outlet flow channel 103. Furthermore, the rotor assembly 23 has a first flow channel 204, which connects the first port 201 and the impeller cavity 203. The impeller cavity 203 connects the second port 202 and the first flow channel 204. The fluid medium in the pump inlet channel 102 can enter the first channel 204 through the first port 201 of the first housing 21, and then enter the impeller cavity 203. Under the rotation of the impeller 231 of the rotor assembly 23, it is pumped out of the impeller cavity 203 through the second port 202, and then to the pump outlet channel 103. The volute 212 is designed to collect the fluid medium thrown out by the impeller 231, thereby avoiding disordered fluid diffusion, reducing turbulence and energy loss, and also providing guidance for the outflow of the fluid medium. The width of the volute 212 is set such that its width is larger closer to the second port 202, which helps to make the pressure distribution more uniform, reduce unbalanced forces, extend the service life of the pump assembly 2, and also helps to maintain a constant flow velocity and reduce hydraulic losses.

[0036] refer to Figure 8 and Figure 18 As shown, the isolation sleeve 22 includes a flow guide 221, which protrudes toward the second port 202, defining a second plane. The second plane is perpendicular to the axial direction of the pump assembly 2. The projection of the volute 212 onto the second plane at least partially coincides with the projection of the flow guide 221 onto the second plane, indicating that the flow guide 221 is within the corresponding range of the volute 212. The flow guide 221 has a sloped structure, and at least a portion of the flow guide 221 is located within the wall forming the second port 202. This reduces the need for the flow guide 221 to have a flow guide surface 221a. The inclination direction of the flow guide surface 221a is consistent with the direction of the fluid medium flowing toward the outlet, which is beneficial for providing guidance for the outflow of the fluid medium and ensuring smooth flow of the fluid medium.

[0037] like Figures 3 to 8As shown, the first housing 21 includes a first sealing portion 214 and a second sealing portion 215, shown along the axial direction of the pump assembly 2. The second sealing portion 215 is located away from the pump inlet flow channel 102 relative to the first sealing portion 214. The first sealing portion 214 is located on the wall forming the first port 201 and protrudes from the impeller cover portion 211. The first sealing portion 214 has a hollow structure, and its hollow portion communicates with the first port 201. The first sealing portion 214 is sealed to the flow channel assembly 1, which helps to ensure the sealing between the first port 201 and the flow channel assembly 1 and prevent internal leakage. The second sealing portion 215 is sealed to the flow channel assembly 1, which helps to ensure the sealing between the pump assembly 2 and the flow channel assembly 1 and prevent external leakage.

[0038] Furthermore, the fluid management component 100 includes a first seal 3, which has an annular structure. In this embodiment, the first seal 3 is an O-ring, a standard part that is easy to replace and maintain, thus saving costs to some extent. The wall forming the receiving cavity 101 includes a second wall portion 12, which is the wall portion where the pump inlet flow channel 102 and the pump outlet flow channel 103 are located. The first sealing portion 214 includes a first groove 214a, the opening of which is oriented towards the pump inlet flow channel 102. At least a portion of the first seal 3 is located in the first groove 214a, and the first seal 3 seals against the wall forming the receiving cavity 101. This end-face sealing method helps reduce wear on the first seal 3, increases its service life, and reduces costs to some extent. In some embodiments, the first seal 3 may also be sleeved on the first sealing portion 214, with the first groove 214a opening toward the outer peripheral wall of the first sealing portion 214. At least a portion of the first seal 3 is located in the first groove 214a, and the first seal 3 seals against the wall forming the pump inlet flow channel 102. The arrangement of the first groove 214a helps to prevent the first seal 3 from falling off or shifting when installing or disassembling the pump assembly 2, further ensuring the sealing between the pump assembly 2 and the flow channel assembly 1 and preventing leakage.

[0039] The fluid management assembly 100 includes a second seal 4. In this embodiment, the second seal 4 is an annular structure and is a sealing gasket. A second sealing portion 215 protrudes from the peripheral wall of the first housing 21. The second sealing portion 215 is fixedly connected or limitedly connected to the second seal 4, for example, by vulcanization, bonding, or welding. The second seal 4 seals against the end of the flow channel assembly 1 toward the pump assembly 2. This end-face sealing method helps reduce wear on the second seal 4, increases its service life, and reduces costs to some extent. In some embodiments, the second seal 4 can be an O-ring. O-rings are standard parts, which are easy to replace and maintain, and help save costs to some extent. The second seal 4 is sleeved on the second sealing portion 215. The second sealing portion 215 has a second groove that opens toward the outer peripheral wall of the second sealing portion 215. At least a portion of the second seal 4 is located in the second groove. The second seal 4 seals against at least a portion of the wall forming the receiving cavity 101, that is, the second seal 4 seals against at least a portion of the first wall portion 11.

[0040] The above examples illustrate the principles and implementation methods of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the technical solution and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of this utility model.
