[0041] It should be understood that although various information may be described using terms such as "first," "second," "third," and "fourth" in this application, this information should not be limited to these descriptions. These terms are only used to distinguish information of the same type from one another. "Multiple" means two or more. Where there is no conflict, the features of the various technical solutions in this application can complement or replace each other.

[0042] The liquid storage device and integrated component of this application can be implemented in various ways. At least one of these implementations can be applied to a vehicle thermal management system, and at least one of these implementations can be applied to other thermal management systems such as a household thermal management system or a commercial thermal management system. The following description uses a vehicle-use liquid storage device as an example, in conjunction with the accompanying drawings.

[0043] Referring to Figures 1-25, the liquid storage device 100 includes a cylindrical body 01, a first cover 12, and a second cover 13. The cylindrical body 01 has a hollow structure with openings at both ends. Along the axial direction of the cylindrical body 01, the first cover 12 is located on one side of the cylindrical body 01, and the second cover 13 is located on the other side of the cylindrical body 01. One end of the cylindrical body 01 is fixedly connected to the first cover 12, and the other end of the cylindrical body 01 is fixedly connected to the second cover 13. The fixed connection can be achieved by welding, threaded connection, bonding, or a combination of both. The cylindrical body 01 includes a shell portion 11 and a flow guide portion 14. The shell portion 11 has a hollow structure with openings at both ends, and the flow guide portion 14 is located inside the shell portion 11. The shell portion 11 and the flow guide portion 14 are an integral structure. An integral structure refers to a structure formed into one piece through methods such as extrusion, forging, die casting, and stamping. The liquid storage device 100 includes a liquid storage cavity 101, a cylindrical body 01, a first cover 12, and a second cover 13 fixedly connected to form the liquid storage cavity 101. Specifically, the wall forming the liquid storage cavity 101 includes a portion of the inner wall of the shell portion 11, a portion of the wall of the first cover 12, and a portion of the wall of the second cover 13. The liquid storage device 100 includes a first port 104 and a third port 102. The first port 104 and the third port 102 are located in at least one of the first cover 12 and the second cover 13. Specifically, the first port 104 is located in one of the first cover 12 and the second cover 13, and the third port 102 is located in the other of the first cover 12 and the second cover 13; or both the first port 104 and the third port 102 are located in the first cover 12, or both are located in the second cover 13. The first port 104 is connected to the liquid storage chamber 101, and the third port 102 is connected to one of the ports of the guide section 14. The liquid storage device 100 of this application is used to store refrigerant in the thermal management system, providing the required liquid supply for the refrigeration system cycle and ensuring stable system operation. The liquid storage device 100 is arranged between the condenser and the evaporator, i.e., downstream of the condenser and upstream of the evaporator; or the liquid storage device 100 is arranged downstream of the evaporator, i.e., downstream of the evaporator and between the compressor, to prevent liquid refrigerant from causing liquid slugging on the compressor.In the relevant solutions, the flow guide 14 and the shell 11 are two separate structures. The flow guide 14 and the shell 11 need to be formed separately. The flow guide 14 is fixed or limited to the cover and then fixedly connected to the shell 11. In this solution, the shell 11 and the flow guide 14 are an integral structure, and both the shell 11 and the flow guide 14 are made of metal. In this embodiment, aluminum alloy is used, but other metal materials can also be used. They are formed into an integral structure through an extrusion process, and the structure is relatively simple. The guide section 14 uses a shared mold, making its manufacturing process relatively simple and reducing manufacturing costs to some extent. Furthermore, compared to related technologies where the cover is fixed or limited to the guide section 14, requiring a limiting structure between them, the structure in this technical solution is relatively complex. The first cover 12, the second cover 13, the shell 11, and the guide section 14 are fixedly connected by welding or bonding, eliminating the need for a limiting and fixed structure on the cover to the guide section 14, resulting in a relatively simple cover structure. In some embodiments, the liquid storage device 100 includes a cylinder 01 and a cover. The cylinder 01 has a hollow structure with one open end, the opening of which faces the cover, and the cylinder 01 and the cover are fixedly connected.

[0044] Referring to Figures 1-16, a specific embodiment of this application will be described in detail. The liquid storage device 100 includes a first cover 12, a second cover 13, and a cylindrical body 01. Along the axial direction of the cylindrical body 01, the cylindrical body 01 is located between the first cover 12 and the second cover 13. The first cover 12 is welded to the cylindrical body 01, and the second cover 13 is welded to the cylindrical body 01. This application adopts a welding method, which can effectively solve the sealing problem and improve the strength to a certain extent. The shell part 11 and the flow guide part 14 are formed into an integral structure. The shell part 11 is a cylindrical structure with open ends and a hollow interior. Of course, in other technical solutions, the formation of the shell part 11 can be set according to requirements. It can be other shapes, such as regular shapes like cubes or cuboids, or it can be designed into an irregular shape according to the spatial arrangement. The main function of the flow guide part 14 is to guide the liquid, gaseous, or gas-liquid two-phase refrigerant into other thermal management components of the thermal management system. The shell portion 11 includes an inner cavity, that is, the hollow structure of the shell portion 11 forms the inner cavity of the shell portion 11. The flow guide portion 14 is located in the inner cavity of the shell portion 11. Along the radial direction of the shell portion 11, the flow guide portion 14 protrudes from the inner wall of the shell portion 11 toward the centerline of the shell portion 11. That is, the flow guide portion 14 and the inner wall of the shell portion 11 are designed to fit together. Alternatively, the cylinder 01 includes a connecting portion. Along the radial direction of the shell portion 11, the connecting portion is located between the shell portion 11 and the flow guide portion 14. One end of the connecting portion is connected to the shell portion 11, and the other end of the connecting portion is connected to the flow guide portion 14. The shell portion 11, the flow guide portion 14 and the connecting portion are integrally formed. In other embodiments, as shown in FIG20, the flow guide 14 is located outside the housing portion 11. Along the radial direction of the housing portion 11, the flow guide 14 protrudes outward from the outer wall of the housing portion 11, meaning the flow guide 14 and the outer wall of the housing portion 11 are designed to fit together. Alternatively, the cylinder 01 includes a connecting portion. Along the radial direction of the housing portion 11, the connecting portion is located between the housing portion 11 and the flow guide 14. One end of the connecting portion is connected to the housing portion 11, and the other end is connected to the flow guide 14. The housing portion 11, the flow guide 14, and the connecting portion are integrally formed. Along the axial direction of the housing portion 11, the flow guide 14 extends from one end of the housing portion 11 to the other end. In this embodiment, the two end faces of the flow guide 14 are flush with the two end faces of the housing portion 11, respectively. This structure facilitates the fit between the cylinder 01 and the cover. The flow guide 14 has a channel 141 with openings at both ends of the channel 14. The channel 141 extends through the flow guide 14 along the axial direction of the housing 11. The axis of the channel 141 forming the flow guide 14 is parallel to and spaced apart from the axis of the inner cavity forming the housing 11. This facilitates the extrusion molding of the housing 11 and the flow guide 14. It should be noted that the parallelism here is not absolute, but within the tolerance range allowed by manufacturing and processing.The flow guide 14 includes a connecting port 142, which is located on the side wall of the flow guide 14. Specifically, an opening is formed on the side wall of the flow guide 14, and the connecting port 142 connects the channel 141 of the flow guide 14 and the inner cavity of the housing 11. The connecting port 142 extends circumferentially along the flow guide 14 to maximize the flow area of ​​the connecting port 142. Normally, the outlet of the liquid storage device 100 is located at a relatively low position within the liquid storage device 100. The connecting port 142 of this application is located on the side wall of the flow guide 14, which facilitates the horizontal placement of the liquid storage device 100. Horizontal placement can be understood as, as shown in Figure 21, with the bottom of the liquid storage device 100 being the side wall of the cylinder 01 along the direction of gravity. When the liquid storage device 100 is laid flat or horizontal, in related technologies, the flow guide 14 and the housing 11 are separate structures, with the flow guide 14 located inside the housing 11. The inlet of the flow guide 14 that connects to the liquid storage chamber 101 is relatively close to the bottom of the liquid storage device 100. The flow guide 14 is usually designed as a curved structure, and its structure and process are relatively complex. In this application, the flow guide 14 and the housing 11 are integrally formed, and the structure is relatively simple.

[0045] The liquid storage device 100 includes a first port 104, a second port 103, and a third port 102, wherein the first port 104, the second port 103, and the third port 102 are located in at least one of the first cover 12 and the second cover 13. It should be noted that the terms "first," "second," and "third" in this application refer to similar features and are interchangeable. As shown in Figures 1-5, the third port 102 is located in the first cover 12, and the second port 103 and the first port 104 are located in the second cover 13. The first cover 12 and the second cover 13 are generally plate-shaped structures. The first cover 12 is welded and fixed to the housing part 11, and the second cover 13 is welded and fixed to the housing part 11. The liquid storage device 100 includes a liquid storage cavity 101, which is formed by the sealed cooperation of the housing part 11, the first cover 12, and the second cover 13. One of the first port 104 and the third port 102 is the inlet of the liquid storage device 100, and the other is the outlet of the liquid storage device 100. In this embodiment, the third port 102 and the second port 103 are the outlets of the liquid storage device 100, and the first port 104 is the inlet of the liquid storage device 100. The third port 102 and the second port 103 are respectively connected to the channel 141 of the guide section 14, and the first port 104 is directly or indirectly connected to the liquid storage chamber 101. Of course, the third port 102 and the second port 103 can also be the inlets of the liquid storage device 100, and the first port 104 can be the outlet of the liquid storage device 100. Depending on the system, one or more flow guides 14 may be provided. In this embodiment, two flow guides 14 are provided, namely a first flow guide 14A and a second flow guide 14B. The first flow guide 14A and the second flow guide 14B are arranged opposite to each other. The first port 104 is connected to the second channel 141B of the second flow guide 14B, and the second port 103 is connected to the first channel 141A of the first flow guide 14A. For example, in one thermal management system, the first port 104 is the inlet of the liquid receiver and is connected to the inlet of the condenser. The third port 102 and the second port 103 are the outlets of the liquid receiver. The third port 102 and the second port 103 are connected to the valve components 30 upstream of different evaporators. The refrigerant coming out of the condenser passes through the first port 104 and the second channel 141B of the liquid receiver, and enters the liquid receiver chamber 101 through the connecting port 142 of the second guide section 14B. The refrigerant, after being dried in the liquid receiver chamber 101, is split after passing through the connecting port 142 of the first guide section 14A and the first channel 141A, and flows out of the liquid receiver through the third port 102 and the second port 103 respectively, and enters the valve components 30.Specifically, the first cover 12 is provided with a third opening 102, which is opposite to one end of the first guide portion 14A and is connected to the first channel 141A of the first guide portion 14A. The first cover 12 has a plate-like structure. Along the thickness direction of the first cover 12, the first cover 12 includes a first channel 122 that penetrates the first cover 12. The opening of the first channel 122 in the first cover 12 is the third opening 102. The end face of the first cover 12 is welded and fixed to the end face of the shell portion 11, the end face of the first guide portion 14A, and the end face of the second guide portion 14B. At least one of the end faces of the shell portion 11 that mate with the first cover 12 or the end faces of the first cover 12 that mate with the shell portion 11 is provided with a solder layer, or a solder sheet is provided between the shell portion 11 and the first cover 12 and fixed by brazing. Similarly, the second cover 13 is provided with a second port 103 and a first port 104. The second port 103 is positioned opposite to the other port of the first guide section 14A, and the first port 104 is positioned opposite to one port of the second guide section 14B. The other port of the second guide section 14B is covered by the first cover 12. The second cover 13 is welded and fixed to the other end face of the housing part 11, the other end face of the first guide section 14A, and the other end face of the second guide section 14B. This will not be described in detail here. In this embodiment, the third port 102 and the second port 103 are the outlets of the liquid storage device 100, and the first port 104 is the inlet of the liquid storage device 100. The third port 102 and the second port 103 are respectively positioned opposite to the two ports of the first guide section 14A. The first guide section 14A and the housing part 11 are extruded into an integral structure, and the axis of the guide section 14 is approximately parallel to the axis of the housing part 11. To connect the first channel 141A of the first flow guide 14A with the third port 102 and the second port 103, the two end faces of the first flow guide 14A are welded and fixed to the first cover 12 and the second cover 13 respectively. Furthermore, a first plane is defined, perpendicular to the axis of the housing 11. The projection of the outer wall of the first flow guide 14A onto the first plane includes the projection of the wall forming the first channel 122 onto the first plane, and the projection of the wall forming the second channel 131 onto the first plane. Fluid in the storage chamber 101 enters the first channel 141A through the communication port 142 of the first flow guide 14A. Depending on the different operating modes of the thermal management system, the fluid in the first channel 141A can selectively flow out of the storage device 100 from the first outlet and / or the second outlet and enter the next thermal management component. In some other embodiments, the liquid storage device 100 also includes a fourth port, which is disposed on the first cover 12 and is connected to another port of the second channel 141B of the second guide portion 14B. That is, the liquid storage device 100 includes two inlets, namely the first port 104 and the fourth port.In the above structure, the two ports of the flow guide 14 can be connected to the thermal management components outside the liquid storage device 100, thus enabling multiple inlets and / or outlets of the liquid storage device 100. The structure is relatively simple. In related technologies, if the liquid storage device is to achieve multiple outlets, multiple flow guides need to be connected, with each flow guide corresponding to one outlet, or the cover needs to be designed with flow channels and external interfaces. This makes the cover structure relatively complex, and the size of the cover will increase accordingly, which is not conducive to the miniaturization of the liquid storage device 1. In addition, the cover needs to be manufactured by forging or die casting, increasing the manufacturing cost. In this application, one flow guide 14 leads out two outlets, that is, the two ports of the flow guide 14 are respectively set to correspond to the two outlets of the liquid storage device 100. The connecting port 142 on the flow guide 14 is set on the side wall of the flow guide 14 and communicates with the liquid storage cavity 101. The structure of the cover is relatively simple, and the flow guide 14 can be located inside the shell 11, which reduces the volume of the liquid storage device 100 to a certain extent. As shown in Figure 21, along the direction of gravity, the first guide section 14A is positioned lower than the second guide section 14B. In this technical solution, the second guide section 14B is connected to the inlet of the liquid storage device 100, i.e., the first port 104, and the first guide section 14A is connected to the outlet of the liquid storage device 100, i.e., the third port 102 and the second port 103. The lower positioning of the first guide section 14A is more conducive to the outflow of fluid. Depending on the different layouts of the thermal management components in the thermal management system, the positions of the third port 102, the second port 103, and the first port 104 can be adjusted according to requirements. The second port 103 and the first port 104 can be located on either the first cover 12 or the second cover 13. That is, the first port 104 and the second port 103 are opened on the first cover 12, while no openings are opened on the second cover 13. The third port 102 and the second port 103 are on different covers, and vice versa.

[0046] In some embodiments, the liquid storage device 100 includes an inlet and an outlet. Specifically, the liquid storage device 100 includes a first port 104 and a third port 102. The first port 104 and the third port 102 are located in either the first cover 12 or the second cover 13. The third port 102 is located in the first cover 12, and the first port 104 is located in the second cover 13. The third port 102 is connected to the liquid storage chamber 101 through a guide portion 14. The first port 104 can be directly connected to the liquid storage chamber 101, or it can be indirectly connected to the liquid storage chamber 101 through the guide portion 14. The connection structure is the same as or similar to the structure described above, and will not be specifically described. When the first port 104 is directly connected to the liquid storage chamber 101, the first port 104 is located on the first cover 12 or the second cover 13. Taking the first port 104 located on the second cover 13 as an example, the second cover 13 is a flat plate structure. Along the thickness direction of the second cover 13, the first port 104 penetrates the second cover 13. The second cover 13 is welded and fixed to the shell part 11, and the first port 104 is connected to the liquid storage chamber 101. The first port 104 is the inlet of the liquid storage device 100, that is, the first port 104 is directly connected to the liquid storage chamber 101. The fluid flows directly into the liquid storage chamber 101 through the first port 104 of the liquid storage device 100 due to gravity. In this technical solution, the structure of the fluid outlet and the guide part 14 connected to the outlet is the same as or similar to the above technical solution, and will not be described in detail here.

[0047] The liquid storage device 100 also includes an adapter 16, which is fixedly connected to the first cover 12 or the second cover 13. The main function of the adapter 16 is to facilitate the connection of the third port 102 of the first cover 12 and / or the second port 103 of the second cover 13 to other thermal management components, i.e., through pipeline connection. Specifically, the adapter 16 includes a connecting channel 161, the opening of which is opposite to and communicates with the second port 103 or the first port 104. The adapter 16 is welded and fixed to the first cover 12, ensuring both sealing and strength.

[0048] To improve the strength of the liquid storage device 100, as shown in Figure 5, the liquid storage device 100 also includes a reinforcing part 111. The reinforcing part 111 is located in the inner cavity of the housing part 11. The reinforcing part 111, the housing part 11, and the flow guide part 14 are formed into an integral structure. Specifically, the reinforcing part 111 is generally a cylindrical structure with open ends and a hollow interior. Along the circumference of the housing part 11, part of the reinforcing part 111 is connected to the flow guide part 14. Along the axial direction of the housing part 11, the two end faces of the reinforcing part 111 are flush with the two end faces of the housing part 11, which is beneficial for the extrusion molding of the housing part 11. The reinforcing part 111 includes a through-hole 1111, which extends radially through the housing part 11, connecting the inner and outer cavities separated by the reinforcing part 111. In some technical solutions, one through-hole 1111 is provided, located around the entire circumference of the reinforcing part 111. In other technical solutions, multiple through-holes 1111 are provided and arranged at intervals on the sidewalls of the reinforcing part 111. The reinforcing part 111 in this application improves the strength of the liquid storage device 100, and the reinforcing part 111 is extruded together with the housing part 11, making the manufacturing process relatively simple.

[0049] The liquid storage device 100 also includes a receiving section 181 and a drying package. The liquid storage device 100 includes a receiving cavity 1812, and the drying package is located in the receiving cavity 1812 for absorbing moisture in the refrigerant. As shown in Figure 9, the receiving part 181 is a hollow cylindrical structure with open ends, and the receiving part 181 is made of metal. One end of the receiving part 181 is welded and fixed to the second cover 13. The receiving part 181 and the second cover 13 cooperate to form at least part of the receiving cavity 1812. That is, the wall of the receiving cavity 1812 includes the part of the second cover 13 and the inner wall of the receiving part 181. The drying container is located in the receiving cavity 1812. The receiving part 181 includes a through hole 1811, which is located on the side wall of the receiving part 181. The through hole 1811 connects the cavities on the inner and outer sides of the receiving cavity 1812. Multiple through holes 1811 are provided. The through holes 1811 extend in the direction of the shell part 11. While ensuring strength, the flow area of ​​the through holes 1811 is increased as much as possible to improve the efficiency of the drying fluid. The liquid storage device 100 also includes a cap 182. The first cover 12 includes an installation port 1241. At least a portion of the cap 182 is located in the installation port 1241, and the cap 182 is fixedly or limitedly connected to the first cover 12, that is, the cap 182 and the first cover 12 are detachably connected.

[0050] In another embodiment, as shown in FIG8, the liquid storage device 100 includes a drying assembly 18, which includes a receiving portion 181 and a pressure cap 182. The receiving portion 181 and the pressure cap 182 are detachably fixedly connected or limitedly connected. The fixed connection includes a threaded connection, and the detachable limited connection includes a snap-fit ​​connection. The drying assembly 18 includes a receiving cavity 1812 for placing molecular sieves. Specifically, the receiving portion 181 is generally a hollow structure with one end open. The receiving portion 181 and the pressure cap 182 cooperate to form the receiving cavity 1812. The wall forming the receiving cavity 1812 includes the inner wall of the receiving portion 181 and part of the end wall of the pressure cap 182. One end of the receiving portion 181 has an opening, and part of the pressure cap 182 is inserted into the inner cavity of the receiving portion 181 through the opening of the receiving portion 181 and is tightly fitted with the inner wall of the receiving portion 181. In this embodiment, the pressure cap 182 and the receiving portion 181 are engaged. The pressure cap 182 includes a limiting groove 1821 located on the side of the pressure cap 182. Along the radial direction of the pressure cap 182, the limiting groove 1821 is recessed inward from the outer wall of the pressure cap 182. The receiving portion 181 includes a latching portion 1813 located on the inner wall of the receiving portion 181 and disposed opposite to the limiting groove 1821. One end of the latching portion 1813 is connected to the inner wall of the receiving portion 181. The other end of the latching part 1813 is a free end. The latching part 1813 includes a sloped structure 1814, which is located at the free end of the latching part 1813. The sloped structure 1814 is spaced apart from the inner wall of the receiving part 181. Along the axial direction of the receiving part 181, the gap between the end of the sloped structure 1814 near the pressure cap 182 and the inner wall of the receiving part 181 is smaller than the gap between the end of the sloped structure 1814 away from the pressure cap 182 and the inner wall of the receiving part 181. In this embodiment, the receiving part 181 is made of plastic, and the latching part 1813 is integrally injection molded with the body of the receiving part 181. The latching part 1813 of the receiving part 181 cooperates with the limiting groove 1821 of the pressure cap 182, that is, part of the latching part 1813 is in contact with the limiting groove 1821, thereby limiting the connection between the pressure cap 182 and the receiving part 181. The number of limiting grooves 1821 and snap-fit ​​parts 1813 shall be at least one, and the limiting grooves 1821 and snap-fit ​​parts 1813 shall be set in a one-to-one correspondence.

[0051] As shown in Figures 3, 8, and 9-12, the first cover 12 includes a mounting portion 124 with a mounting opening 1241. A portion of the drying assembly 18 is located within the liquid storage chamber 101. The drying assembly 18 is detachably fixedly connected or limitedly connected to the first cover 12. The fixed connection includes a threaded connection, and the limited connection includes a snap-fit ​​connection. Along the axial direction of the housing portion 11, the mounting portion 124 protrudes upwards or downwards relative to the end face of the first cover 12. The mounting portion 124 and the first cover 12 are an integral structure, formed by extrusion, forging, die casting, or stamping. Alternatively, the mounting portion 124 and the first cover 12 are separate structures, with the mounting portion 124 welded to the first cover 12 for fixed connection. In this embodiment, the mounting portion 124 and the first cover 12 are integrally formed. The pressure cap 182 is snapped and fixed to the first cover 12. The drying assembly 18 includes a snap-fit ​​member 183. The mounting portion 124 has a slot 1242 located on the inner wall of the mounting portion 124. The slot 1242 is arranged circumferentially along the mounting portion 124 and radially along the first cover 12. The slot 1242 is recessed outward on the inner wall of the mounting portion 124. The pressure cap 182 includes a first limiting portion 1822. Along the axial direction of the housing portion 11, the pressure cap 182... The first limiting part 1822 of 2 is away from the mounting opening 1241 of the first cover 12 relative to the slot 1242. The outer wall of the cover 182 is press-fitted with the inner wall of the mounting part 124. The snap-fit ​​member 183 is located in the slot 1242 of the cover 182. The lower end face of the snap-fit ​​member 183 abuts against the first limiting part 1822 of the cover 182, and the upper end face of the snap-fit ​​member 183 abuts against the upper wall forming the slot 1242, thereby restricting the displacement of the cover 182 along the axial direction of the housing part 11 and snap-fitting and fixing the drying assembly 18 and the first cover 12. The first cover 12 includes a second stepped portion 1243, which is located on the inner wall of the mounting portion 124. Along the axial direction of the housing portion 11, the second stepped portion 1243 is away from the mounting opening 1241 relative to the slot 1242. The pressure cap 182 includes a second limiting portion 1823. The first limiting portion 1822 and the second limiting portion 1823 are disposed opposite to each other. The second limiting portion 1823 abuts against the stepped wall of the second stepped portion 1243, thereby restricting the pressure cap 182 from moving towards the bottom of the cylinder. In this embodiment, the snap-fit ​​member 183 is a C-shaped snap ring. The drying assembly 18 also includes a sealing member 184. The pressure cap 182 includes a sealing groove 185, which is located below the second stepped portion 1243 along the axial direction of the housing portion 11. At least part of the sealing member 184 is located within the sealing groove 185 to prevent liquid leakage from the liquid storage chamber 101.In this embodiment, at least one of the mounting portions 124 of the pressure cap 182 and the first cover 12 includes an annular groove 1824. For example, the annular groove 1824 is located on the outer wall of the pressure cap 182 and is recessed toward the center of the pressure cap 182. The wall portion forming the sealing groove 185 is located in the annular groove 1824 and partly in the inner wall of the mounting portion 124. Alternatively, the annular groove 1824 is located on the inner wall of the mounting portion 124, and the wall portion forming the sealing groove 185 is located in the annular groove 1824 and partly in the outer wall of the pressure cap 182. Or, the wall portion forming the annular groove 1824 is located in the pressure cap 182 and partly in the mounting portion 124. During installation, first place the molecular sieve into the receiving cavity 1812 of the receiving part 181, then snap the cap 182 and the receiving part 181 together. Place the sealing element 184 in the annular groove 1824 of the cap 182. Insert the bottom of the drying assembly 18 from the mounting port 1241 of the mounting part 124 of the first cover 12 into the liquid storage cavity 101 until the second limiting part 1823 of the first cover 12 abuts against the stepped wall of the second stepped part 1243 of the mounting part 124. Then, insert the retaining spring into the retaining groove 1242 of the mounting part 124 to limit and fix the drying assembly 18 to the first cover 12. When disassembling the drying assembly 18, first remove the retaining spring from the retaining groove 1242 of the mounting part 124, and then remove the drying assembly 18 from the liquid storage cavity 101.

[0052] In this embodiment, the drying component 18 is detachably installed within the liquid storage chamber 101. Compared to related technologies, where the drying component 18 is sealed within the liquid storage device 100 and cannot be replaced without damage, during the service life of the liquid storage device, the amount of molecular sieve used in the drying component 18 increases to achieve its water absorption function, thus increasing the volume of the drying component 18. This directly leads to a larger overall volume of the liquid storage tank with a fixed effective volume, which is detrimental to the lightweight and miniaturized design requirements of the integrated components. In this application, the drying component 18 is detachably installed within the liquid storage chamber 101, allowing for periodic replacement of the drying component 18. Consequently, the volume of the liquid storage device 100 can be reduced, and after-sales troubleshooting is easier, reducing maintenance difficulty.

[0053] In related technologies, the liquid storage device is equipped with a filter element, which is located at the inlet or outlet of the liquid storage device. For example, a conduit is installed in the liquid storage device, with one end of the conduit connected to the outlet of the liquid storage device and the other end of the conduit connected to the liquid storage chamber. The filter element is installed at one of the ports of the conduit and is sealed inside the liquid storage chamber. It cannot be replaced without damage. If too many impurities accumulate in the later stage, it will affect the performance of the thermal management system.

[0054] To address the aforementioned problems, as shown in Figures 3, 8, and 13-15, the liquid storage device 100 includes a flow guide 14 located within the liquid storage chamber 101. The end of the flow guide 14 is fixedly connected to the first cover 12. The flow guide 14 includes a channel 141 communicating with the liquid storage chamber 101. The first cover 12 includes a third opening 102, which is opposite to and communicates with the channel 141. The filter element 15 is detachably fixed within the channel 141 of the flow guide 14. The fixed connection includes welding, bonding, and other connection methods. The flow guide 14 is located either within the liquid storage chamber 101 or outside the liquid storage chamber 101, i.e., outside the housing portion 11, and communicates with the liquid storage chamber 101. In this application, the third opening 102 of the first cover 12 is disposed opposite to the channel 141 of the flow guide 14. The filter element 15 is detachably fixed in the channel 141 of the flow guide 14, meaning that the filter element 15 can pass through the third opening 102 into the channel 141 of the flow guide 14, and the filter element 15 can also pass through the third opening 102 to be removed from the channel 141 of the flow guide 14. In related technical solutions, the filter element 15 is usually placed on the outer wall of the flow guide 14 and cannot be replaced without damage.

[0055] In the thermal management system, the outlet of the liquid storage device 100 is typically connected to other thermal management components within the system. Generally, the outlet of the liquid storage device 100 is connected to these components via an external connecting pipe 17. The external connecting pipe 17 is detachably fixed or positioned at the outlet of the liquid storage device 100. Specifically, the liquid storage device 100 includes an adapter 16 for connecting the external connecting pipe 17. The adapter 16 is fixedly connected to the first cover 12. The adapter 16 includes a connecting channel 161 that extends through the adapter 16 and is positioned opposite to the third port 102. A portion of the external connecting pipe 17 is located within the connecting channel 161, and the external connecting pipe 17 is detachably connected to the adapter 16. In this embodiment, the adapter 16 has a block-shaped structure, and its end face is fitted or in contact with the end face of the first cover 12 and is welded in place. As shown in Figure 4, the first cover 12 includes a first stepped portion 121, located at the end of the first cover 12 away from the guide portion 14. The opening of the first stepped portion 121 on the first cover 12 forms the third opening 102. The adapter 16 includes a protrusion 162, which protrudes outward relative to the end face of the adapter 16. The outer wall of the protrusion 162 is interference-fitted with the side wall of the first stepped portion 121. The end of the adapter 16 is welded and fixed to the end of the first cover 12. This structure is beneficial for the adapter 16. The positioning of the adapter 16 fixedly assembled with the first cover 12 reduces the use of clamps or simplifies the structure of the clamps. In other embodiments, the positions of the protrusion 162 and the first step 121 are interchangeable. That is, the adapter 16 includes the first step 121, the first cover 12 includes the protrusion 162, the protrusion 162 protrudes outward relative to the end of the first cover 12, the third opening 102 is formed on the protrusion 162, the outer wall of the protrusion 162 is press-fitted with the side wall of the first step 121, and the end of the adapter 16 is welded and fixed to the end of the first cover 12. The adapter 16 includes a connecting channel 161, and part of the outer pipe 17 is located in the channel 141. That is, the outer pipe 17 communicates with the third opening 102 and the channel 141 of the conduit portion, and the outer pipe 17 is detachably connected to the adapter 16. It can be understood that when it is necessary to remove the filter element 15, the outer pipe 17 is removed first, and then the filter element 15 is removed from the guide portion 14. The specific structure of the detachable connection between the outer pipe 17 and the adapter 16 is shown in Figures 18-19. The outer pipe 17 is provided with a pipe section 173 and a flange section 171. The flange section 171 is located outside the pipe section 173, or in other words, the flange section 171 is sleeved on the pipe section 173 and is fixedly connected to the pipe section 173. The adapter 16 includes a threaded hole 163, and the flange section 171 includes a through hole 172. At least a portion of the pipe section 173 is located in the connecting channel 161 of the adapter 16. Nuts or screws pass through the through hole 172 of the flange section 171 and are fixedly connected to the threaded hole 163 of the adapter 16, thereby fixing the outer pipe 17 and the adapter 16.

[0056] The filter element 15 includes a main body 151 and a filter part 152. The main body 151 is located on the outer periphery of the filter part 152 and is used to support the filter part 152. The main body 151 and the filter part 152 are injection molded into an integral structure. The main body 151 is press-fitted with the inner wall of the flow guide 14, or the main body 151 is press-fitted with the wall forming the third opening 102. In this embodiment, the filter element 15 is generally an elongated columnar structure. The filter part 152 has filter holes for filtering impurities in the fluid. A first plane is defined, which is perpendicular to the axial direction of the housing part 11. The first cover 12 includes a first channel 122 that penetrates the first cover 12. The opening of the first channel 122 in the first cover 12 is the third opening 102. The projection of the inner wall of the flow guide 14 onto the first plane falls within the projection range of the wall forming the first channel 122 onto the first plane. The projection of the inner wall of the flow guide 14 onto the first plane also falls within the projection range of the wall forming the connecting channel 161 onto the first plane. The position and size relationship of the flow guide 14, the first channel 122, and the connecting channel 161 are restricted to facilitate the filter element 15 to pass through the connecting channel 161 of the adapter 16 and the first channel 122 of the first cover 12 into the flow guide 14.

[0057] In one embodiment, as shown in Figures 15-16, the main body 151 is generally a hollow cylindrical structure. The main body 151 includes a first section 1511 and a second section 1512. The first section 1511 is located at at least one end of the main body 151. The outer diameter of the first section 1511 is larger than the outer diameter of the second section 1512. The first section 1511 is press-fitted with the inner wall of the flow guide 14, and the second section 1512 is clearance-fitted with the inner wall of the flow guide 14. The first section 1511 is located closer to the outlet of the liquid storage device 100 than the second section 1512. The press-fitted first section 1511 and the inner wall of the flow guide 14 fix the filter element 15 and prevent impurities from entering the system through the outer wall of the filter element 15 and entering the outlet. The second section 1512 is fitted with the inner wall of the guide section 14 with a gap. Impurities in the fluid enter the inner cavity of the main body 151 after being filtered by the filter section 152, and flow out through the second port 103. The impurities remain in the gap between the second section 1512 and the inner wall of the guide section 14, or because the filter element 15 is located at the outlet, the impurities remain in the liquid storage chamber 101, thus increasing the impurity storage space and reducing the blockage of the filter holes by impurities. The second section 1512 includes multiple through ports 1513, which penetrate the inner and outer walls of the main body 151. The filter section 152 blocks the multiple through ports 1513. Of course, the filter element 15 can also be located at the inlet of the liquid storage device 100, such as in the flow guide section 14 connected to the first port 104. That is, the filter element 15 is located at the inlet of the liquid storage device 100. The fluid flowing in from the inlet of the liquid storage device 100 is first filtered by the filter element 15 and then enters the liquid storage chamber 101 through the communication port 142 of the flow guide section 14. Then it enters the channel 141 of the flow guide section 14 through the communication port 142 connected to the outlet and flows out from the outlet of the liquid storage device 100. The appropriate placement position of the filter element 15 can be selected according to the requirements of the thermal management system.

[0058] In other embodiments, as shown in Figures 13-14, the main body 151 is generally a hollow cylindrical structure. The main body 151 includes a reinforcing part 1515 and a mating part 1514. The mating part 1514 is located at at least one end of the reinforcing part 1515 and protrudes from the outer wall of the reinforcing part 1515. The mating part 1514 is press-fitted with the inner wall of the guide part 14, and the reinforcing part 1515 is clearance-fitted with the inner wall of the guide part 14. The reinforcing part 1515 includes a first part 1516 and a second part 1517. The first part 1516 and the second part 1517 are generally plate-shaped and intersecting. In this embodiment, the first part 1516 and the second part 1517 are arranged in a cross shape. Along the circumference of the main body 151, the filter part 152 blocks the space formed between the first part 1516 and the second part 1517, forming the inner cavity of the main body 151. In this embodiment, a reinforcing part 1515 is provided to support the filtering part 152. The reinforcing part 1515 is formed by the intersection of the first part 1516 and the second part 1517, which increases the strength of the main body part 151.

[0059] The filter element 15 also includes a clamping part 153, which is located at the end of the main body 151 near the third port 102. The clamping part 153 is integral with the main body 151. The clamping part 153 has a mounting hole 1531, which facilitates operation and makes it easy to hook the filter element 15 out of the guide part 14.

[0060] The above embodiments describe a liquid storage device 100 with only one outlet. In some embodiments, the liquid storage device 100 includes a third outlet 102 and a second outlet 103, with the third outlet 102 and the second outlet 103 located in one of the first cover 12 and the second cover 13, respectively. The two ports corresponding to the channel 141 of the flow guide 14 correspond to the third outlet 102 and the second outlet 103, respectively. The flow guide 14 has a connecting port 142 that connects to the liquid storage chamber 101. The connecting port 142 is positioned opposite to the filter element 15. It can be understood that the fluid flowing into the flow guide 14 from the connecting port 142 is divided into two paths: one flows out through the filter element 15 from the third outlet 102, and the other flows out through the filter element 15 from the second outlet 103. In this embodiment, two outlets correspond to one filter element 15, which reduces the number of components and lowers the cost.

[0061] Referring to Figures 22-25, this application provides an integrated component, which includes the aforementioned liquid storage device 100. The liquid storage device 100 includes a first port 104, a second port 103, and a third port 102, wherein the third port 102 and the second port 103 are the outlets of the liquid storage device 100, and the first port 104 is the inlet of the liquid storage device 100. The third port 102 is located on the first cover 12, and the second port 103 and the first port 104 are located on the second cover 13. The liquid storage device 100 includes... The adapter 16 is used to connect the outer pipe 17. The adapter 16 is welded and fixed to the first cover 12 or is an integral structure. The adapter 16 is disposed opposite to the third port 102. The integrated assembly includes a first plate 20 and a flow channel 201. The first plate 20 is located on the side of the second cover 13 opposite to the housing part 11. The first plate 20 is welded and fixed to the second cover 13. The wall portion forming the flow channel 201 is located on the second cover 13, and the wall portion forming the flow channel 201 is located on the first plate 20. The integrated assembly includes a mounting block 31 and a valve component 30. The mounting block 31 is fixedly connected to either the second cover 13 or the first plate 20. The mounting block 31 includes a mounting cavity 310, and the valve component 30 is mounted in the mounting cavity 310. The mounting cavity 310 of the mounting block 31 is connected to the flow channel 201 of the integrated assembly. Of course, in other embodiments, the adapter 16 is welded and fixed to the second cover 13, the adapter 16 is disposed opposite to the first opening 104, the first plate 20 is located on the side of the first cover 12 opposite to the housing portion 11, the first plate 20 is welded and fixed to the first cover 12, the wall portion forming the flow channel 201 is located on the first cover 12, and the wall portion forming the flow channel 201 is located on the first plate 20. It should be noted that, according to the requirements of the thermal management system, the first plate 20 is fixedly connected to at least one of the first cover 12 or the second cover 13, and the inlet and outlet of the liquid storage device 100 are located in at least one of the first cover 12 or the second cover 13. In the integrated component of this application, the cover of the liquid storage device 100 and the plate forming the flow channel 201 of the integrated component are shared, which simplifies the structure of the flow channel plate forming the flow channel 201 in the integrated component to a certain extent, and is conducive to the lightweighting of the integrated component.

[0062] The integrated component also includes a heat exchanger 40, which includes an end plate 41. The end plate 41 is welded and fixed to the first plate 20 or the second cover 13. The heat exchange channel of the heat exchanger 40 is connected to a portion of the flow channel. That is, the cylinder 01 is welded and fixed to the second cover 13, and the end plate 41 of the heat exchanger 40 is welded and fixed to the second cover 13. In other words, the cylinder 01 and the heat exchanger 40 can be located on the same side of the second cover 13 or on different sides of the second cover 13. Alternatively, if the cylinder 01 is welded and fixed to the second cover 13, and the end plate 41 of the heat exchanger 40 is welded and fixed to the first plate 20, then the heat exchanger 40 and the cylinder 01 are located on different sides of the flow channel plate. A suitable method can be selected according to design requirements and space. In related technologies, the heat exchanger and the flow channel plate are fixed together by bolts or screws. The heat exchanger also includes a mounting plate, which is welded and fixed to the end plate of the heat exchanger. The mounting plate has lugs, and screws or nuts pass through the mounting holes of the lugs and are threaded to the flow channel plate. The liquid storage assembly is also fixed to the flow channel plate by bolts or screws. Threaded holes or through holes are provided on the end cap of the liquid storage assembly to fix it to the flow channel plate, or a bracket is provided to fix it to the flow channel plate. In the above technical solution, the end plate 41 of the heat exchanger 40 is welded and fixed to the second cover 13 or the first plate 20 forming the flow channel. This can be understood as the mounting plate of the heat exchanger 40 serving as the plate forming the flow channel in related technologies. The cylinder 01 of the liquid storage device 100 is welded and fixed to the second cover 13 forming the flow channel. That is, the second cover 13 and the cylinder 01 cooperate to form the liquid storage chamber 101. The second cover 13 can serve as the end cap or cover plate of the liquid storage device 100. In other words, the mounting plate of the heat exchanger 40, one of the plates of the flow channel plate, and the cover plate of the liquid storage device 100 are shared.
