[0034] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0035] In this disclosure, unless otherwise stated, directional terms such as "up," "down," "left," and "right" are generally used to define the orientation of the accompanying drawings, such as the first direction, second direction, and third direction. Figure 3 As shown, "inner" and "outer" refer to the inner and outer parts of the relevant components. Furthermore, terms such as "first" and "second" are used only for descriptive distinction and should not be interpreted as indicating or implying relative importance.

[0036] In the description of this disclosure, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can be a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0037] With the development of thermal management systems, integrated development is the main development trend in the current thermal management industry. This means that integrated thermal management components are formed by connecting flow channels and other related parts together to form a complete unit.

[0038] In the related technology, the two plates of the flow channel plate of the thermal management integrated component may have small deformations or dimensional tolerances during manufacturing. This can easily lead to localized loose sealing when the two plates are fitted together, resulting in leakage and other problems. Moreover, the connection between the two plates of the flow channel plate is made using ordinary welding technology, which requires multiple welding processes to complete, making the process very cumbersome.

[0039] Therefore, such as Figures 1-6 As shown, one aspect of this disclosure provides a thermal management integrated component, including a water tank 1 and a flow channel plate 2.

[0040] Water tank 1 is used to store cooling water. Flow channel plate 2 is connected to water tank 1. Cooling water flow channel is provided in flow channel plate 2. Cooling water flow channel is connected to water tank 1 and is used to supply cooling water flow.

[0041] The flow channel plate 2 includes a first plate 21 and a second plate 22. The first plate 21 and the second plate 22 are connected to each other and enclose each other to form a cooling water flow channel. The second plate 22 is provided with a plurality of spaced-apart pressing and positioning parts 23. The pressing and positioning parts 23 are used to cooperate with the pressing tooling so that the second plate 22 and the first plate 21 are tightly fitted during welding.

[0042] The first plate 21 and the second plate 22 are connected face to face, meaning that one side of the first plate 21 and one side of the second plate 22 are positioned opposite each other and attached together, and the cooling water channel is located between the first plate 21 and the second plate 22.

[0043] In the above technical solution, the clamping and positioning part 23 enables the clamping and positioning of the first plate 21 and the second plate 22 during laser welding. This allows for clamping at different positions of the first plate 21 and the second plate 22, ensuring a certain degree of clamping between them. This facilitates large-area laser welding, guarantees connection strength, and prevents gaps and leakage. It also solves the problem of loose fit caused by slight deformation or dimensional tolerances in the manufacturing process. Furthermore, the clamping and positioning part 23 can cooperate with clamping fixtures for easy connection, allowing the clamping fixtures to quickly clamp and fix the first plate 21 and the second plate 22, improving manufacturing efficiency.

[0044] To better facilitate cooperation with the clamping fixture, in one embodiment of this disclosure, the clamping positioning part 23 is optionally constructed as a column protruding from the second plate 22, and the clamping positioning part 23 extends in a direction perpendicular to the second plate 22. The clamping positioning part 23 is located on the side of the second plate 22 opposite to the first plate 21.

[0045] The column protrudes from the second plate 22. The column can be integrally formed with the second plate 22 or welded to it. The column can be connected to the clamping fixture, allowing the fixture to clamp and position the column while ensuring sufficient contact area for effective clamping and preventing interference. In some examples, the clamping fixture may also have a positioning groove into which the column portion can extend for positioning and connection, thereby better achieving the clamping effect on the first plate 21 and the second plate 22.

[0046] Alternatively, in another embodiment of this disclosure, the clamping and positioning part 23 is configured as a positioning groove formed in the second plate 22, with the groove opening facing away from the second plate 22 in a direction perpendicular to the second plate 22. The positioning groove allows the protruding structure of the clamping fixture to extend into it, achieving contact and thus realizing positioning and clamping effects.

[0047] In order to further improve the uniformity of pressing the first plate 21 and the second plate 22, optionally, in one embodiment of the present disclosure, the pressing and positioning part 23 includes at least one first point 231 and a plurality of second points 232, the at least one first point 231 being close to the middle of the second plate 22, and the plurality of second points 232 being arranged on both sides of the first point 231 in a first direction.

[0048] The first point 231 can position the middle of the second plate 22, which is conducive to the connection between the clamping tool and the middle of the second plate 22 to achieve the clamping effect. The second point 232 is located on both sides of the first point 231, which can position the second plate 22 near the edge, which is conducive to the connection between the clamping tool and the second plate 22 near the edge to achieve the clamping effect. This ensures uniformity when clamping the entire first plate 21 and the second plate 22, and can more effectively avoid gaps between the first plate 21 and the second plate 22.

[0049] In some examples, there is one first point 231 located in the middle of the second plate 22, and five second points 232, with two and three second points 232 respectively set on both sides of the first point 231 in the first direction. Of course, it should be noted that the number of first points 231 and second points 232 can also be set according to actual needs, and there are no further restrictions here.

[0050] Optionally, in one embodiment of this disclosure, the second plate 22 is provided with a welding area 26, and the second plate 22 and the first plate 21 are welded together by using a laser welding process to weld the welding area 26. Compared to ordinary welding processes, using laser welding significantly improves welding reliability. Furthermore, with the cooperation of the clamping and positioning part 23 and the clamping fixture, full contact of the welding area 26 can be ensured, guaranteeing the quality of the laser welding.

[0051] To further improve the connection strength and efficiency of the first plate 21 and the second plate 22, optionally, in one embodiment of this disclosure, the side of the second plate 22 covering the first plate 21 is provided with a first reinforcing rib 24 and a second reinforcing rib 25. The first reinforcing rib 24 and the second reinforcing rib 25 are spaced apart and opposite to each other. The area between the first reinforcing rib 24 and the second reinforcing rib 25 of the second plate 22 is designated as a welding area 26. The second plate 22 and the first plate 21 are connected by laser welding through the welding area 26. The first reinforcing rib 24 and the second reinforcing rib 25 are configured to limit the overflow of welding material. Through the cooperation of the clamping and positioning part 23 and the clamping fixture, the connection can be made using laser welding, which greatly improves the welding reliability and reduces the overflow problem caused by ordinary welding compared to ordinary welding.

[0052] The first reinforcing rib 24 and the second reinforcing rib 25 extend along the extension direction of the welding area 26. In some examples, the first reinforcing rib 24, the second reinforcing rib 25, and the welding area 26 are close to the edge of the second plate 22, with a portion extending along the circumferential edge of the second plate 22 and another portion extending to the middle of the second plate 22, thereby improving the connection strength. The relative arrangement of the first reinforcing rib 24 and the second reinforcing rib 25 can structurally strengthen the left and right sides of the welding area 26, increasing the structural strength of the first plate 21 and the second plate 22 after welding, as well as improving the structural strength of the entire flow channel plate. At the same time, the first reinforcing rib 24 and the second reinforcing rib 25 can also provide a blocking effect, limiting overflow, improving the welding effect and aesthetics, and ensuring the effect of large-area laser welding.

[0053] Optionally, in one embodiment of this disclosure, the second plate 22 is made of a light-transmitting material, and the first plate 21 is made of a light-absorbing material and is opaque. The light-transmitting nature of the second plate 22 facilitates the determination of the welding area 26, enables large-area laser welding operations, ensures welding effectiveness, and improves connection strength.

[0054] To facilitate the assembly of the first plate 21 and the second plate 22, in one embodiment of this disclosure, the first plate 21 is provided with a first assembly positioning part, and the second plate 22 is provided with a second assembly positioning part 28. The first assembly positioning part and the second assembly positioning part 28 can cooperate with each other to position and connect the second plate 22 with the first plate 21.

[0055] It is understandable that during the assembly and connection of the first plate 21 and the second plate 22, the first assembly positioning part and the second assembly positioning part 28 can be connected, allowing the first plate 21 and the second plate 22 to be aligned and connected together to form structures such as cooling water flow channels, avoiding misalignment and improving assembly efficiency. In some examples, the number of the first assembly positioning part and the second assembly positioning part 28 can be two, and they are set one-to-one. Of course, the number of the first assembly positioning part and the second assembly positioning part 28 can also be set as needed, without further restrictions. In some examples, one of the first assembly positioning part and the second assembly positioning part 28 can be a protrusion, and the other can be a groove.

[0056] Optionally, in one embodiment of this disclosure, the second plate 22 is connected to the water tank 1. The second plate 22 is provided with an inlet 29 that communicates with the cooling water flow channel. The water tank 1 is provided with a water inlet 11, and the inlet 29 communicates with the water inlet 11. This arrangement facilitates communication between the cooling water flow channel and the water tank 1. Since the water tank 1 is connected to the second plate 22, the second plate 22 primarily supports the water tank 1 and does not bear excessive load on other structures. The first plate 21 can be used to support other structures and also allows for connection between the first plate 21 and related structures, enabling the installation and fixation of the thermal management integrated assembly.

[0057] Optionally, in one embodiment of this disclosure, a partition 17 is provided inside the water inlet 11, which divides the water inlet 11 into a first part 171 and a second part 172. The first part 171 is located above the second part 172. The cooling water in the cooling water channel can enter the water tank 1 through the first part 171 to discharge gas, and the cooling water in the water tank 1 enters the cooling water channel through the second part 172.

[0058] It is understandable that the cooling water in the cooling water channel can circulate once within the water tank 1, thereby allowing the gas carried by the cooling water in the cooling water channel to be discharged, achieving exhaust. It is also understandable that the cooling water flowing in from the first part 171 flows back to the cooling water channel from the second part 172. In some examples, the partition 17 is a partition plate, horizontally positioned, located in the middle of the water inlet 11, thus dividing the water inlet 11 into two halves.

[0059] The second part 172 can still be used to replenish cooling water to the cooling water channel. In other words, the cooling water in the water tank 1 can flow into the cooling water channel through the second part 172.

[0060] Optionally, in one embodiment of this disclosure, a turbulence channel 18 is provided inside the water tank 1. The turbulence channel 18 is connected to the first part 171 and the second part 172 respectively. The turbulence channel 18 is used for cooling water flow and gas-liquid separation. By providing the turbulence channel 18, the flow direction of the cooling water can be continuously changed, thereby facilitating gas separation and gas discharge. In some examples, the turbulence channel 18 is provided with multiple baffles to change the flow direction of the cooling water and form turbulence in the cooling water.

[0061] Optionally, in one embodiment of this disclosure, the water tank 1 includes a high-temperature water tank 12 and a low-temperature water tank 13, which are connected to each other. The water inlet 11 includes a first water inlet 111 and a second water inlet 112. The first water inlet 111 is located in the low-temperature water tank 13, and the second water inlet 112 is located in the high-temperature water tank 12. The first water inlet 111 is connected to the water inlet 29. The axes of the first water inlet 111 and the water inlet 29 both extend along a second direction. The second water inlet 112 is used to connect to the engine water pump 8. The top of the high-temperature water tank 12 is provided with a high-temperature pressure cover 121 and an overflow port 122, and the top of the low-temperature water tank 13 is provided with a low-temperature pressure cover 131.

[0062] The high-temperature water tank 12 and the low-temperature water tank 13 are integrated together, and can be integrally molded, thereby improving the integration. The first water inlet 111 is used to allow water from the low-temperature water tank 13 to flow into the cooling water channel, and the second water inlet 112 is used to guide water from the high-temperature water tank 12 to the engine water pump 8. The axes of the first water inlet 111 and the water inlet 29 both extend along the second direction, so that the low-temperature water tank 13 can be located on one side of the second plate 22, the water inlet 29 is opened on one side of the second plate 22, and the first water inlet 111 is opened on one side of the low-temperature water tank 13. When the low-temperature water tank 13 is connected to the second plate 22, the first water inlet 111 and the water inlet 29 can be connected, and a sealing ring 72 can be provided between the first water inlet 111 and the water inlet 29.

[0063] The high-temperature pressure cover 121 and overflow port 122 can be used for engine system exhaust, while the low-temperature pressure cover can be used for low-temperature circuit exhaust. In some examples, level sensors can also be installed inside the high-temperature water tank 12 and the low-temperature water tank 13 to detect the water level height in the high-temperature water tank 12 and the low-temperature water tank 13, respectively. Min and max level lines can also be set on the side walls of the high-temperature water tank 12 and the low-temperature water tank 13. The high-temperature water tank 12 and the low-temperature water tank 13 can have a certain degree of transparency to facilitate water level observation, and can be made of thin metal or plastic.

[0064] Optionally, in one embodiment of this disclosure, the water tank 1 includes a first vessel 14 extending along a third direction and a second vessel 15 extending along a second direction. The first vessel 14 and the second vessel 15 are connected. A mounting bracket 16 is provided on the first vessel 14 and is connected to the flow channel plate 2. The second vessel 15 is located above the first vessel 14 and the flow channel plate 2. The second vessel 15 includes an upper shell 151 and a lower shell 152. The upper shell 151 covers the lower shell 152, and the lower shell 152 is connected to and communicates with the first vessel 14. The second direction is set at an angle to the third direction.

[0065] The first vessel body 14 and the second vessel body 15 can be integrally formed, meaning they are a single unit, divided into two parts, with their interiors completely interconnected. Both the aforementioned high-temperature water tank 12 and low-temperature water tank 13 can include the first vessel body 14 and the second vessel body 15. The second vessel body 15 is further divided into an upper shell 151 and a lower shell 152 for easy assembly. It is understood that the lower shell 152 can be integrally formed with the first vessel body 14, and the upper shell 151, manufactured separately, can be placed on top of the lower shell 152 and connected for fixation, forming a space for holding water.

[0066] The first tank 14 can be connected to the flow channel plate 2 via a mounting bracket 16. The mounting bracket 16 can be connected to the flow channel plate 2 via bolts. The first tank 14 can be located on the side of the flow channel plate 2, that is, on the side of the second plate 22. The first tank 14 can fit snugly against the second plate 22. The second tank 15 is located above the first tank 14 and the flow channel plate 2, extending along a second direction. This makes the water tank 1 formed by the first tank 14 and the second tank 15 an irregularly shaped structure, with a wider top and narrower bottom. This structure can adapt to the structure of the flow channel plate 2 and connect with the side of the flow channel plate 2, achieving a small volume, which helps to reduce weight and meet the vehicle's lightweight requirements. In some examples, the third direction is parallel to the flow channel plate 2, and the second direction is perpendicular to the flow channel plate 2. The second direction is perpendicular to the third direction. Of course, in other examples, the second direction and the third direction may not be perpendicular, but may be set at an acute or obtuse angle.

[0067] Optionally, in one embodiment of this disclosure, the first plate 21 has a first surface 211 and a second surface 212 disposed opposite to each other, the second plate 22 covers the first surface 211, and the second surface 212 is provided with at least one first connection port 3 and at least one second connection port 4, the axis of the first connection port 3 extends along a first direction, and the axis of the second connection port 4 extends along a second direction; wherein the first direction and the second direction are arranged at an angle.

[0068] The first connection port 3 and the second connection port 4 are used to connect with relevant structures in the thermal management system to form the entire thermal management system. The first connection port 3 and the second connection port 4 are respectively connected to the cooling water channels of the flow channel plate, enabling different flow directions of the cooling water and allowing the thermal management system to operate in different modes. The first connection port 3 and the second connection port 4 extend in two directions, which facilitates adaptation to the positions of relevant components, and also facilitates industrial manufacturing. In some examples, the first connection port 3 is located on one side of the first plate 21, and the second connection port 4 is located on the other side of the first plate 21. There can be four second connection ports 4, which can be spaced apart. Alternatively, there can be four first connection ports 3, which can be spaced apart, with three first connection ports 3 arranged side-by-side.

[0069] Optionally, in one embodiment of this disclosure, the first plate 21 has a first surface 211 and a second surface 212 disposed opposite to each other, the second plate 22 covers the first surface 211, the second surface 212 is provided with a valve core mounting groove 5, and a plurality of valve ports 51 communicating with the cooling water flow channel are opened in the valve core mounting groove 5.

[0070] The thermal management integrated assembly also includes a multi-way valve core 6 and a valve cover 61. The multi-way valve core 6 is rotatably connected to the valve core mounting groove 5. The rotation of the multi-way valve core 6 can open or close multiple valve ports 51. The valve cover 61 covers the multi-way valve core 6 and is connected to the groove of the valve core mounting groove 5. By providing the valve core mounting groove 5 on the second surface 212, the multi-way valve core 6 is designed to be embedded and can rotate within the valve core mounting groove 5. This eliminates the need for a valve seat structure, reducing the number of parts. Thus, the valve core mounting groove 5, the multi-way valve core 6, and the flow channel plate 2 are integrated into a single unit, improving the integration of the thermal management integrated assembly.

[0071] The second plate 22 serves as a back plate, fitting against the first surface 211 of the first plate 21. The valve core mounting groove 5 on the second surface 212 of the first plate 21 can be used to install the multi-way valve core 6. Multiple valve ports 51 within the valve core mounting groove 5 can communicate with cooling water channels, allowing for changes in the cooling water flow direction. This thermal management system can thus have multiple operating modes. The valve cover 61 covers the multi-way valve core 6, confining it within the valve core mounting groove 5 and preventing it from detaching, thus ensuring the ability to change the cooling water flow direction.

[0072] It is understandable that the multi-way valve core 6 has an internal channel. When the multi-way valve core 6 rotates within the valve core mounting groove 5, the internal channel connects with different valve ports 51, enabling changes in the flow direction of cooling water and switching between operating modes. For valve ports 51 not connected to the internal channel, the flow is blocked, preventing cooling water from flowing. In some examples, the valve core mounting groove 5 is integrally formed with the first plate 21, and the multi-way valve core 6 is installed into the valve core mounting groove 5 through the groove opening.

[0073] Optionally, in one embodiment of this disclosure, the valve port 51 is disposed at the bottom of the valve core mounting groove 5, and a sealing element 7 is provided between the multi-way valve core 6 and the bottom of the valve core mounting groove 5. The sealing element 7 can seal the gap between the multi-way valve core 6 and the valve core mounting groove 5 to prevent cooling water leakage.

[0074] The inner passage of the multi-way valve core 6 is located at the end of the multi-way valve core 6 facing the bottom of the valve core mounting groove 5, so that the inner passage of the multi-way valve core 6 can be directly opposite the valve port 51. Thus, during the rotation of the multi-way valve core 6, the inner passage of the multi-way valve core 6 can selectively connect with different valve ports 51. Therefore, the sealing element 7 set between the multi-way valve core 6 and the bottom of the valve core mounting groove 5 can produce a sealing effect, preventing leakage between the passage and the valve port 51.

[0075] To further ensure the sealing effect without affecting the connection between the channel port and the valve port 51, optionally, in one embodiment of this disclosure, the sealing element 7 includes a sealing ring 72 and a sealing gasket 71. The sealing gasket 71 is sandwiched between the valve core 6 of the multi-way valve and the bottom of the valve core mounting groove 5. The sealing gasket 71 has multiple through holes 73, which correspond one-to-one with multiple valve ports 51. The sealing ring 72 is sleeved on the sealing gasket 71.

[0076] The sealing gasket 71 is clamped between the valve core 6 of the multi-way valve and the bottom of the valve core mounting groove 5. A through hole 73 on the sealing gasket 71 allows communication between the channel opening and the valve port 51, enabling cooling water to flow through. Simultaneously, the sealing gasket 71 provides a seal. A sealing ring 72 is fitted onto the outer wall of the sealing gasket 71, providing a secondary seal and improving the sealing performance. In some examples, the width of the sealing gasket 71 corresponds to the width of the valve core mounting groove 5, and the size of the through hole 73 corresponds to the size of the valve port 51, thus ensuring both the cooling water flow rate and the sealing effect.

[0077] Optionally, in some examples, the bottom of the valve core mounting groove 5 is provided with an inner groove, which facilitates the insertion of the sealing gasket 71, thereby limiting and fixing the sealing gasket 71 and ensuring the sealing effect. The outer ring of the inner groove is used to place the sealing ring 72 to achieve secondary sealing.

[0078] Optionally, in one embodiment of this disclosure, the sealing element 7 includes a sealing sleeve, which is integrally fitted onto the outer wall of the multi-way valve core 6. In the axial direction of the multi-way valve core 6, the sealing sleeve protrudes from the multi-way valve core 6 and connects to the bottom of the valve core mounting groove 5 to achieve a sealing effect.

[0079] Optionally, in one embodiment of this disclosure, the multi-way valve core 6 includes a seven-way valve core 62 and a three-way valve core 63, and the valve core mounting groove 5 includes a seven-way valve mounting groove 52 and a three-way valve mounting groove 53. The seven-way valve core 62 is connected to the seven-way valve mounting groove 52, and the three-way valve core 63 is connected to the three-way valve mounting groove 53. This arrangement allows for changes in the direction of cooling water flow in multiple directions, enabling the constructed thermal management system to have more operating modes. It also reduces the number of individual valves, improves integration, and facilitates connection and assembly.

[0080] Optionally, in one embodiment of this disclosure, the first plate 21 has a first surface 211 and a second surface 212 disposed opposite to each other, and the second plate 22 covers the first surface 211. A groove is formed on the first surface 211, and the second plate 22 closes the opening of the groove so that the groove forms a cooling water channel. This arrangement facilitates the formation of a cooling water channel and is convenient for processing and manufacturing.

[0081] Optionally, in another embodiment of this disclosure, the first plate 21 has a first surface 211 and a second surface 212 disposed opposite to each other, the second plate 22 covers the first surface 211, and a groove is formed on the side of the second plate 22 facing the first surface 211. The first plate 21 closes the opening of the groove so that the groove forms a cooling water flow channel.

[0082] Optionally, in another embodiment of this disclosure, the first plate 21 has a first surface 211 and a second surface 212 disposed opposite to each other, and the second plate 22 covers the first surface 211. The first surface 211 and the side of the second plate 22 covering the first surface 211 are both provided with grooves, and the openings of the two grooves overlap each other so that the two grooves together form a cooling water flow channel.

[0083] Optionally, in one embodiment of this disclosure, the thermal management integrated component further includes at least one water pump 8, which is connected to the bottom of the flow channel plate 2, and the inlet of the water pump 8 is in communication with the cooling water flow channel. By integrating the water pump 8, the cooling water flow can be driven, and the integrated design of the water pump 8 can improve the integration level of the thermal management integrated component.

[0084] A second aspect of this disclosure also provides a thermal management system including the aforementioned thermal management integrated component.

[0085] A third aspect of this disclosure also provides a vehicle including the aforementioned thermal management integrated component, or the aforementioned thermal management system.
