Description

Technical Field

[0001] The present invention relates to the technical field of thermal management systems for new energy vehicles, and in particular to an electronic water valve, a thermal management system thereof, and a vehicle. Background Art

[0002] The thermal management system for new energy vehicles includes a battery thermal management system and a motor electronic control thermal management system. Temperature significantly impacts the efficiency of battery operation and discharge. At low temperatures, the depth of discharge is shallow, and prolonged operation at low temperatures shortens the battery life. Therefore, to ensure efficient charging and discharging of the battery pack, a thermal management system is required to heat or cool the battery pack. Motor operation generates significant heat, raising the motor temperature and affecting output power, reducing power, and in severe cases, causing the vehicle to stall. Therefore, motor cooling is necessary. During other operations of the new energy vehicle thermal management system, some components may also require heating.

[0003] Traditional thermal management systems for batteries and motors in new energy vehicles rely on multiple electronic valves to control each medium flow channel within the thermal management system. These valves are connected in series or parallel, allowing the thermal management system to operate as separate circulation loops or adjust them to form a single circulation loop. Traditional thermal management systems involve multiple electronic valves, resulting in complex and costly structures and complicated medium flow channels. Summary of the Invention

In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0054] Please refer to Figure 1 and Figure 2The technical solution of the present invention proposes an electronic water valve 01, which includes a valve housing 10 and a valve core 30. The valve housing 10 is provided with a first inlet port 11, a second inlet port 12, a first outlet port 13, a second outlet port 14, a third outlet port 15 and a fourth outlet port 16; the valve core 30 is rotatably mounted on the valve housing 10, so that when the first inlet port 11 is connected to the fourth outlet port 16, the second inlet port 12 is connected to the second outlet port 14 or the first outlet port 13; when the first inlet port 11 is connected to the first outlet port 13, the second inlet port 12 is connected to the fourth outlet port 16 or the third outlet port 15; when the first inlet port 11 is connected to the second outlet port 14, the second inlet port 12 is connected to the third outlet port 15.

[0055] The valve housing 10 is provided with two inlet ports, namely a first inlet port 11 and a second inlet port 12, and four outlet ports, namely a first outlet port 13, a second outlet port 14, a third outlet port 15, and a fourth outlet port 16. Fluid flows in through the first inlet port 11 and the second inlet port 12 and out through the first outlet port 13, the second outlet port 14, the third outlet port 15, and the fourth outlet port 16. A valve core 30 is rotatably mounted on the valve housing 10. Different passages are formed in the valve core 30. When the valve core 30 rotates, the passages in the valve core 30 can communicate with different inlet ports and different outlet ports, forming five different circulation modes: a first circulation mode, a second circulation mode, a third circulation mode, a fourth circulation mode, and a fifth circulation mode.

[0056] When the valve core 30 is in the initial position, the first inlet port 11 is connected to the fourth outlet port 16, and the second inlet port 12 is connected to the second outlet port 14. The electronic water valve 01 is in the first flow mode. At this time, fluid flows into the first inlet port 11 and out of the fourth outlet port 16. Simultaneously, fluid flows into the second inlet port 12 and out of the second outlet port 14. In the first flow mode, the first inlet port 11 can communicate with the fourth outlet port 16 through one of the pathways, and the second inlet port 12 can communicate with the second outlet port 14 through another pathway. The two pathways do not interfere with each other, and the remaining outlet ports are not connected.

[0057] The valve core 30 rotates a certain angle, connecting the first inlet port 11 to the fourth outlet port 16 and the second inlet port 12 to the first outlet port 13. The electronic water valve 01 is in the second flow mode. At this point, fluid flows in through the first inlet port 11 and out through the fourth outlet port 16. Simultaneously, fluid flows in through the second inlet port 12 and out through the first outlet port 13. In the first flow mode, the first inlet port 11 can communicate with the fourth outlet port 16 via one of the pathways, while the second inlet port 12 can communicate with the first outlet port 13 via another pathway. The two pathways do not interfere with each other, and the remaining outlet ports are not interconnected.

[0058] The valve core 30 continues to rotate a certain angle, connecting the first inlet port 11 to the first outlet port 13, and the second inlet port 12 to the fourth outlet port 16. The electronic water valve 01 is in the third flow mode. At this point, fluid flows into the first inlet port 11 and out of the first outlet port 13. Simultaneously, fluid flows into the second inlet port 12 and out of the fourth outlet port 16. In the first flow mode, the first inlet port 11 can communicate with the first outlet port 13 through one of the pathways, and the second inlet port 12 can communicate with the fourth outlet port 16 through another pathway. The two pathways do not interfere with each other, and the remaining outlet ports are not connected.

[0059] The valve core 30 continues to rotate a certain angle, connecting the first inlet port 11 to the first outlet port 13, and the second inlet port 12 to the third outlet port 15. The electronic water valve 01 is now in the fourth flow mode. At this point, fluid flows into the first inlet port 11 and out of the first outlet port 13. Simultaneously, fluid flows into the second inlet port 12 and out of the third outlet port 15. In the first flow mode, the first inlet port 11 can connect to the first outlet port 13 through one of the pathways, and the second inlet port 12 can connect to the third outlet port 15 through another pathway. The two pathways do not interfere with each other, and the remaining outlet ports are not connected.

[0060] The valve core 30 continues to rotate a certain angle, connecting the first inlet port 11 to the second outlet port 14, and the second inlet port 12 to the third outlet port 15. The electronic water valve 01 is now in the fifth flow mode. At this point, fluid flows into the first inlet port 11 and out of the second outlet port 14. Simultaneously, fluid flows into the second inlet port 12 and out of the third outlet port 15. In the first flow mode, the first inlet port 11 can communicate with the second outlet port 14 through one of the pathways, and the second inlet port 12 can communicate with the third outlet port 15 through another pathway. The two pathways do not interfere with each other, and the remaining outlet ports are not connected.

[0061] The present invention's technical solution utilizes two inlet ports and four outlet ports on the valve housing 10, with the valve core 30 rotatably mounted thereto. This allows the inlet ports to communicate with different outlet ports, thereby enabling switching between different flow modes. The electronic water valve 01 described in the present invention offers a wide range of flow circuit modes, compatible with one-to-many continuous switching capabilities, and suitable for more integrated thermal management systems.

[0062] Please refer to Figure 2The first inlet port 11 and the second inlet port 12 are respectively arranged on opposite sides of the valve housing 10, the first outlet port 13 and the second outlet port 14 are arranged on one side wall between the first inlet port 11 and the second inlet port 12, and the third outlet port 15 and the fourth outlet port 16 are arranged on the other side wall between the first inlet port 11 and the second inlet port 12. The first inlet port 11 and the second inlet port 12 are respectively arranged on opposite sides of the valve housing 10, with a gap between the first inlet port 11 and the second inlet port 12. Cutting along the axial direction of the valve housing 10 with the connecting line of the first inlet port 11 and the second inlet port 12 as a tangent, the valve housing 10 has two oppositely arranged side walls, one of which is provided with the first outlet port 13 and the second outlet port 14, and the other side of which is provided with the third outlet port 15 and the fourth outlet port 16. Ports are provided on all four sides of the valve housing 10, with the first inlet port 11 and the second inlet port 12 oppositely arranged. The first outlet port 13 and the second outlet port 14 are located on one side of the first inlet port 11, and the third outlet port 15 and the fourth outlet port 16 are located on the other side. Likewise, the second inlet port 12 has the third outlet port 15 and the fourth outlet port 16 on one side and the first outlet port 13 and the second outlet port 14 on the other side.

[0063] The first outlet port 13 and the third outlet port 15 are positioned opposite each other, while the second outlet port 14 and the fourth outlet port 16 are positioned opposite each other. The first outlet port 13 is positioned directly below the second outlet port 14, and the third outlet port 15 is positioned directly below the fourth outlet port 16. The first outlet port 13 and the third outlet port 15 are positioned opposite each other, with the extended axes of the first and third outlet ports 13 and 15 coinciding. The center points of the first and third outlet ports 13 and 15 are equidistant from the bottom surface of the valve housing 10 and from the center points of the first and second inlet ports 11 and 12. The second outlet port 14 and the fourth outlet port 16 are positioned opposite each other, with the extended axes of the second and fourth outlet ports 14 and 16 coinciding. The center points of the second and fourth outlet ports 14 and 16 are equidistant from the bottom surface of the valve housing 10 and from the center points of the first and second inlet ports 11 and 12. The first outlet port 13 is positioned directly below the second outlet port 14, and the projection of the center point of the second outlet port 14 in the axial direction of the valve housing 10 coincides with the projection of the center point of the first outlet port 13. The third outlet port 15 is located directly below the fourth outlet port 16 in the axial direction of the valve housing 10, and the projection of the center point of the fourth outlet port 16 coincides with the projection of the center point of the third outlet port 15. To ensure that the flow rates of all passages are the same in different circulation modes, the sizes of the first inlet port 11, the second inlet port 12, the third outlet port 15, and the fourth outlet port 16 should be the same. However, during the manufacturing process, there may be slight errors in the sizes of the first outlet port 13 and the second outlet port 14. In the axial direction of the valve housing 10, the projections of the center points of the first outlet port 13 and the second outlet port 14 should coincide. Similarly, during the manufacturing process, there may be slight errors in the sizes of the third outlet port 15 and the fourth outlet port 16. In the axial direction of the valve housing 10, the projections of the center points of the third outlet port 15 and the fourth outlet port 16 should coincide. In other preferred embodiments, different communication modes require different flow rates, and the sizes of the first outlet port 13 and the second outlet port 14 can be significantly different. The projections of the center points of the first outlet port 13 and the second outlet port 14 along the axis of the valve housing 10 should also coincide with each other to avoid situations where outlet ports that are not allowed to communicate in one mode are not connected. Similarly, the third outlet port 15 and the fourth outlet port 16 can be significantly different, but the projections of the center points of the first outlet port 13 and the second outlet port 14 along the axis of the valve housing 10 should also coincide with each other.

[0064] The valve housing 10 includes a first end and a second end, with a first inlet port 11 and a second inlet port 12 disposed opposite each other between the first and second ends. The distances between the first inlet port 11 and the second inlet port 12 and the first end are greater than the distance between the first outlet port 13 and the first end, and less than the distance between the second outlet port 14 and the first end. The axes of the first inlet port 11 and the second inlet port 12 are perpendicular to the axes of the first outlet port 13, the second outlet port 14, the third outlet port 15, and the fourth outlet port 16. The first inlet port 11 and the second inlet port 12 are disposed on opposite sides of the valve housing 10, with the extended lines of the axes of the first inlet port 11 and the second inlet port 12 coinciding. The center points of the first inlet port 11 and the second inlet port 12 are equidistant from the bottom surface of the valve housing 10. The distance from first outlet port 13 to the first end is a1, the distance from second outlet port 14 to the first end is a2, the distance from first inlet port 11 to the first end is A1, and the distance from second inlet port 12 to the first end is A2, satisfying the following relationship: a1 < A1 < a2, a1 < A2 < a2, A1 = A2. The axes of first inlet port 11 and second inlet port 12 are perpendicular to the axes of first outlet port 13, second outlet port 14, third outlet port 15, and fourth outlet port 16. It can be understood that the first inlet port 11, the second inlet port 12, the first outlet port 13, the second outlet port 14, the third outlet port 15 and the fourth outlet port 16 are relatively arranged on the upper, middle and lower layers of the valve housing 10, the second outlet port 14 and the fourth outlet port 16 are relatively arranged in the upper layer, the first inlet port 11 and the second inlet port 12 are relatively arranged in the middle layer, the axes of the first inlet port 11 and the second inlet port 12 are perpendicular to the axes of the second outlet port 14 and the fourth outlet port 16, the first outlet port 13 and the third outlet port 15 are arranged in the lower layer, the axes of the first outlet port 13 and the third outlet port 15 are perpendicular to the axes of the first inlet port 11 and the second inlet port 12, and the projections of the axes of the first outlet port 13 and the third outlet port 15 coincide with the projections of the axes of the second outlet port 14 and the fourth outlet port 16.

In this first flow mode, the electronic water valve 01 has two pathways. In one pathway, fluid flows from the first inlet port 11 into the first open groove 321, then out of the fourth outlet port 16 via the second open groove 311.

The first inlet port 11 is connected to the first outlet port 13 through the first open groove 321 and the third open groove 331 in sequence, and the second inlet port 12 is connected to the third outlet port 15 through the first opening 323, the through chamber 38 and the fifth opening 334 in sequence.

[0072] Please refer to Figure 7 The valve core 30 continues to rotate a certain angle, and the electronic water valve 01 enters the fourth flow mode. In this fourth flow mode, the electronic water valve 01 has two pathways. One pathway allows fluid to flow from the first inlet port 11 into the first open groove 321, then out of the first outlet port 13 via the third open groove 331. The other pathway allows fluid to flow from the second inlet port 12 into the first opening 323, through the through chamber 38, from the middle structure 32 to the lower structure 33, and out of the third outlet port 15 via the fifth opening 334. These two pathways do not interfere with each other, and the remaining outlet ports are not interconnected.

[0073] Please refer to Figure 3 The first inlet port 11 is connected to the second outlet port 14 through the first open groove 321 and the second open groove 311 in sequence, and the second inlet port 12 is connected to the third outlet port 15 through the first opening 323, the through chamber 38 and the fifth opening 334 in sequence.

[0074] Please refer to Figure 8 The valve core 30 continues to rotate a certain angle, and the electronic water valve 01 enters the fifth flow mode. In this fifth flow mode, the electronic water valve 01 has two pathways. In one pathway, fluid flows from the first inlet port 11 into the first open groove 321, then out of the second outlet port 14 via the second open groove 311. The other pathway allows fluid to flow from the second inlet port 12 into the first opening 323, through the through chamber 38, from the middle structure 32 to the lower structure 33, and out of the third outlet port 15 via the fifth opening 334. These two pathways do not interfere with each other, and the remaining outlet ports are not interconnected.

[0075] Please refer to Figure 3 The valve core 30 is provided with a plurality of interconnected open grooves and openings, arranged along the outer periphery of the valve core 30 in upper, middle, and lower layers. The upper structure 31 is provided with a second open groove 311, a fourth opening 312, and a second opening 313.

The lower structure 33 is provided with a third open groove 331, a fifth opening 334, and a third opening 333. The valve core 30 is rotatably mounted to the valve housing 10, so that the inlet port communicates with different outlet ports through different open grooves or openings, thereby enabling switching between different flow modes.

[0076] It is understandable that when the electronic water valve 01 is in operation, all open slots and all ports of the valve core 30 are filled with fluid. Regardless of the angle at which the valve core 30 rotates, or the flow mode in which the electronic water valve 01 is in, the first inlet port 11 is always connected to the first open slot 321, and the second inlet port 12 is always connected to the first port 323. Fluid always flows from the first inlet port 11 into the first open slot 321, and fluid always flows from the second inlet port 12 into the first port 323. When the valve core 30 rotates, some open slots or ports are in the same position as the outlet port, and fluid flows out from the outlet port connected to the open slot or port. Some open slots or ports are staggered with the outlet port and are blocked by the valve housing 10. In different modes, the outlet port connected to the open slot or port is different, and fluid can flow out from different outlet ports. In any flow mode, there is only one outlet port connected to the first inlet port 11 and only one outlet port connected to the second inlet port 12. Furthermore, the outlet port connected to the first inlet port 11 and the outlet port connected to the second inlet port 12 are two different outlet ports. In any flow mode, the electronic water valve 01 has two non-interfering pathways.

[0078] The valve core 30 includes a vertical plate 36, which is curved with an arc angle of less than 180° and has both a convex and a concave surface. A first rotating disk 341 is connected to the top of the vertical plate 36, and a second rotating disk 342 is connected to the bottom of the vertical plate 36.

The first baffle 351 is close to the first rotating disk 341, and the second baffle 352 is close to the second rotating disk 342. The valve core 30, which is composed of the vertical plate 36, the first rotating disk 341, the first baffle 351, the second baffle 352, and the second rotating disk 342, is cylindrical.

[0079] The first turntable 341 and the first baffle 351 form the upper structure 31. A plurality of first partitions 314 are vertically arranged between the first turntable 341 and the first baffle 351. The first partitions 314 divide the space between the first turntable 341 and the first baffle 351 into multiple small spaces. A panel 37 connected to the first partition 314 is also provided between the first turntable 341 and the first baffle 351. The panel 37 seals each small space into a closed space. The panel 37 is provided with an opening, which is connected to the closed space. The closed space with the opening forms a second open groove 311, a second opening 313, and a fourth opening 312. The second open groove 311 is connected to the convex surface of the vertical plate 36, and the second opening 313 and the fourth opening 312 are connected to the concave surface of the vertical plate 36.

[0080] The first baffle 351 and the second baffle 352 form the middle structure 32. Two second partitions 324 are vertically mounted on the first baffle 351 and the second baffle 352. The two second partitions 324 are connected to the two sides of the vertical plate 36, separating the first open groove 321 from the first opening 323. The first open groove 321 is connected to the convex surface of the vertical plate 36, and the first opening 323 is connected to the concave surface of the vertical plate 36.

[0081] The second baffle 352 and the second turntable 342 form the lower structure 33. A plurality of third partitions 332 are disposed between the second baffle 352 and the second turntable 342. The third partitions 332 divide the space between the second baffle 352 and the second turntable 342 into a plurality of small spaces. A panel 37 is also disposed between the second baffle 352 and the second turntable 342, connecting the third partitions 332. The panel 37 seals each small space into a closed space. The panel 37 has an opening that communicates with the closed space. The closed space with the opening forms a third open slot 331, a third opening 333, and a fifth opening 334. The third open slot 331 is connected to the convex surface of the vertical plate 36, and the third opening 333 and the fifth opening 334 are connected to the concave surface of the vertical plate 36.

[0082] A through chamber 38 is provided on the concave surface of the vertical plate 36. It extends axially through the upper structure 31, the middle structure 32, and the lower structure 33 of the valve core 30, providing communication with the first port 323, the second port 313, the third port 333, the fourth port 312, and the fifth port 334. During manufacturing, to facilitate processing, the through chamber 38 can be connected to the bottom of the valve core 30. A blocking block can be provided at the bottom of the through chamber 38 to seal it and reduce internal leakage.

[0083] The central angle of the first opening 323 is greater than the central angle of the first open groove 321, and the first opening 323 is provided with a reinforcing rib 322. If the curvature of the vertical plate 36 is less than 180°, then the convex surface of the vertical plate 36 is less than 180°. The first open groove 321 and the first opening 323 are separated on both sides of the vertical plate 36. The central angle of the first open groove 321 set on the convex surface of the vertical plate 36 is less than 180°, while the central angle of the first opening 323 set on the concave surface of the vertical plate 36 is greater than 180°. The first opening 323 is provided with a reinforcing rib 322, which connects the first baffle 351 and the second baffle 352. The reinforcing rib 322 can improve the stability of the valve core 30, avoid the situation where the curvature of the first opening 323 is too large and causes structural instability, and can extend the service life of the valve core 30.

[0084] The second open groove 311 is arranged above the first open groove 321 and is connected to the first open groove 321, so that the first inlet port 11 can be connected to the fourth outlet port 16 or the second outlet port 14, and the projected ends of the first open groove 321 are outside the projected ends of the second open groove 311; the second opening 313 is arranged above the first opening 323, and there is a gap between the second opening 313 and the fourth opening 312 and the second open groove 311, so that the second inlet port 12 can be connected to the second outlet port 14; the fourth opening 312 is arranged above the first opening 323, and the fourth opening 312 is adjacent to the second open groove 311, so that the second inlet port 12 can be connected to the fourth outlet port 16; the central angle of the fourth opening 312 is the same as the central angle of the second opening 313.

[0085] The second open slot 311 is positioned above and connected to the first open slot 321. The central angle of the second open slot 311 is smaller than that of the first open slot 321, and the projection of the second open slot 311 falls within the projection of the first open slot 321. When the electronic water valve 01 is in the first and second flow modes, fluid can enter through the first inlet port 11, flow through the first and second open slots 321, and then exit through the fourth outlet port 16. When the electronic water valve 01 is in the fifth flow mode, fluid can enter through the first inlet port 11, flow through the first and third open slots 321, and then exit through the second outlet port 14.

[0086] The second opening 313 is positioned above the first opening 323, with a gap between the second opening 313 and the fourth opening 312 and the second open slot 311. The central angle of the second opening 313 is smaller than that of the first opening 323, and the projection of the second opening 313 falls within the projection of the first opening 323. When the electronic water valve 01 is in the first flow mode, fluid can enter through the second inlet port 12, flow through the first and second openings 323, and then out through the second outlet port 14.

[0087] The fourth opening 312 is positioned above the first opening 323 and adjacent to the second open slot 311. The central angle of the fourth opening 312 is smaller than that of the first opening 323 and is the same as that of the second opening 313. Furthermore, the projection of the fourth opening 312 falls within the projection of the first opening 323. When the electronic water valve 01 is in the first flow mode, fluid can enter through the second inlet port 12, flow sequentially through the first opening 323 and the fourth opening 312, and then exit through the fourth outlet port 16.

[0088] The third open groove 331 is arranged below the first open groove 321 and is connected to the first open groove 321, so that the first inlet port 11 can be connected to the first outlet port 13, and one end of the projection of the third open groove 331 falls into the projection of the first open groove 321, and the other end is outside the projection of the first open groove 321; the third opening 333 is arranged below the first opening 323, the third opening 333 is adjacent to the third open groove 331, and there is a gap between the third opening 334, so that the second inlet port 12 can be connected to the first outlet port 13, and the two ends of the projection of the first opening 323 are outside the two ends of the projection of the third opening 333; the fifth opening 334 is arranged below the first opening 323 and is connected to the first opening 323, so that the second inlet port 12 can be connected to the third outlet port 15, and the two ends of the projection of the first opening 323 are outside the two ends of the projection of the fifth opening 334; the central angle of the fifth opening 334 is greater than the central angle of the third opening 333.

[0089] The third open slot 331 is positioned below and connected to the first open slot 321. The central angle of the third open slot 331 is smaller than that of the first open slot 321. One end of the third open slot 331's projection falls within the projection of the first open slot 321, while the other end lies outside the projection of the first open slot 321. This means that the third open slot 331 is offset from the first open slot 321 by a certain angle. When the electronic water valve 01 is in the third and fourth flow modes, fluid can enter the first inlet port 11, flow through the first and third open slots 321, and then out of the first outlet port 13.

[0090] The third opening 333 is positioned below the first opening 323, adjacent to the third open slot 331 and spaced apart from the fifth opening 334. The central angle of the third opening 333 is smaller than that of the first opening 323, and the projection of the third opening 333 falls within the projection of the first opening 323. When the electronic water valve 01 is in the second flow mode, fluid can enter through the second inlet port 12, flow sequentially through the first opening 323 and the third opening 333, and then exit through the first outlet port 13.

[0091] The fifth opening 334 is disposed below and communicates with the first opening 323.

[0092] The first rotating disk 341 and the second rotating disk 342 are each provided with ribs 343. Ribs 343 are located on the top surface of the first rotating disk 341 and the bottom surface of the second rotating disk 342. Ribs 343 are arranged in a ripple pattern centered on the axis of the valve core 30. Ribs 343 reduce frictional resistance during the rotation of the valve core 30 and also serve as a guide and positioning mechanism.

[0093] Please refer to Figure 9 The electronic water valve 01 also includes a sealing gasket 20, which is installed between the valve housing 10 and the valve core 30. The sealing gasket 20 is provided with through-holes 21 corresponding to the first inlet port 11, the second inlet port 12, the first outlet port 13, the second outlet port 14, the third outlet port 15, and the fourth outlet port 16. Sealing ribs 22 are provided around the through-holes 21. The outer wall of the sealing gasket 20 is in contact with the electronic water valve 01. The sealing gasket 20 has multiple through-holes 21, which are the same number, size, and location as the ports on the electronic water valve 01. Sealing ribs 22 are provided around the through-holes 21 to enhance the sealing effect of the sealing gasket 20 when the ports are connected to the passageway of the valve core 30. The sealing ribs 22 extend axially and circumferentially around the through-holes 21. The sealing ribs 22 are staggered horizontally and vertically on the sealing gasket 20 to separate the various openings, ensuring that the various ports of the valve housing 10 remain independent and the electronic water valve 01 will not leak.

[0094] The sealing rib 22 is serrated. The serrated sealing rib 22 can produce significant elastic deformation when subjected to pressure, generating sufficient pressure between the sealing gasket 20 and the valve housing 10. The sealing gasket 20 has greater compliance with the valve housing 10 and the valve core 30, thereby improving the sealing effect of the sealing gasket 20.

[0095] The sealing gasket 20 includes an elastic deformation layer and a low friction layer, and the elastic deformation layer is attached to the outer periphery of the low friction layer. The inner layer of the sealing gasket 20 is a low friction layer, which is smooth. When the valve core 30 rotates, the friction between the two is small, which can reduce the motor torque. The outer layer of the sealing gasket 20 is an elastic deformation layer, and the elastic deformation layer is provided with a sealing rib 22. The sealing rib 22 can produce a large elastic deformation after being compressed, and sufficient pressure is generated between the sealing gasket 20 and the valve housing 10. The sealing gasket 20 has a large compliance with the valve housing 10 and the valve core 30, which improves the sealing effect of the sealing gasket 20 and can effectively reduce internal leakage. The elastic deformation layer and the low friction layer can be separately molded and then compounded using other processes, or they can be co-molded.

[0096] The elastic deformation layer is made of EPDM (ethylene propylene diene monomer). EPDM is a copolymer of ethylene, propylene, and a small amount of non-conjugated diene. It is a type of ethylene propylene diene monomer (EPDM), designated as EPDM (Ethylene Propylene Diene Monomer). EPDM offers excellent properties such as low cost, weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, and a wide operating temperature range. With a density of 0.87 kg / m³, EPDM can be extensively oil-filled and filled with fillers, thus reducing the cost of rubber products. EPDM lacks polarity and has a low degree of unsaturation, making it highly resistant to various polar chemicals such as alcohols, acids, alkalis, oxidants, refrigerants, detergents, animal and vegetable oils, ketones, and fats. EPDM has a wide operating temperature range, with a minimum operating temperature of -40°C to -60°C. It can be used at 130°C for long periods and at 150°C to 200°C for short or intermittent use.

[0097] The low-friction layer is made of polytetrafluoroethylene (PTFE). Polytetrafluoroethylene (Teflon or PTFE), a polymer compound formed by the polymerization of tetrafluoroethylene, exhibits excellent chemical stability, corrosion resistance, sealing properties, high lubricity and non-stick properties, electrical insulation, and good aging resistance. PTFE can withstand long-term use at temperatures between 200°C and 260°C and remains flexible at -100°C. It is corrosion-resistant and resistant to aqua regia and all organic solvents. It is highly lubricating, possessing the lowest coefficient of friction among plastics (0.04). It is also non-sticky, possessing the lowest surface tension among solid materials and resisting adhesion to any substance.

[0098] Please refer to Figure 1The electronic water valve 01 also includes a valve cover 50 and a drive device 40. The valve cover 50 is installed above the valve housing 10. The valve cover 50 is provided with a mounting hole for connecting the drive device 40. The electronic water valve 01 includes a valve housing 10, a sealing gasket 20, a valve core 30, a valve cover 50 and a drive device 40. The valve core 30 is installed inside the valve housing 10. The sealing gasket 20 is arranged between the valve housing 10 and the valve core 30. The valve cover 50 is installed on the top of the valve housing 10 and the valve core 30. The drive device 40 is arranged above the valve cover 50. The valve cover 50 is used to limit the axial movement of the valve core 30. When the valve core 30 rotates, due to the restriction of the valve cover 50, the valve core 30 will not be displaced in the axial direction, thereby avoiding the misalignment of the open groove or through-port with the port, which prevents the fluid from flowing out of the outlet port or flows out of other outlet ports. The valve cover 50 is provided with a mounting hole to cooperate with the installation and fixation of the drive device 40. The driving device 40 can include any power source that can drive the valve core 30, driving the valve core 30 to execute according to a pre-set path. In one embodiment, the valve core 30 can also be provided with a hollow support column, which is arranged in the through chamber 38. One end of the support column is connected to the block, and the block can be provided with a protrusion that extends into the interior of the support column. The block is clamped with the support column to facilitate the installation and removal of the block. The other end of the support column is connected to the valve cover 50, or the other end of the support column is provided with a connector, and the valve cover 50 is installed above the valve core 30 through the connector.

[0099] The technical solution of the present invention is to provide two inlet ports, namely a first inlet port 11 and a second inlet port 12, on the valve housing 10; and four outlet ports, namely a first outlet port 13, a second outlet port 14, a third outlet port 15, and a fourth outlet port 16. On one side of the valve core 30, from top to bottom, are sequentially provided with a second open groove 311, a first open groove 321, and a third open groove 331, which can communicate with each other. On the other side of the valve core 30, the upper layer is provided with a second opening 313 and a fourth opening 312, the middle layer is provided with a first opening 323, and the lower layer is provided with a third opening 333 and a fifth opening 334. The axial core of the valve core 30 is provided with a through chamber 38, which extends through the upper, middle, and lower layers of the valve core 30 to connect the first opening 323, the second opening 313, the third opening 333, the fourth opening 312, and the fifth opening 334. The valve core 30 is rotatably mounted on the valve housing 10, allowing the first inlet port 11 and the second inlet port 12 to communicate with different outlet ports through different open slots or openings, without interfering with each other, thereby enabling switching between different flow modes. The electronic water valve 01 of the present invention offers a wide range of flow circuit modes, compatible with one-to-many continuous switching functionality, and suitable for more integrated thermal management systems.

[0100] A sealing gasket 20 is also positioned between the valve housing 10 and the valve core 30. Through-holes 21 are provided on the sealing gasket 20, corresponding one-to-one with the ports of the valve housing 10. The sealing gasket 20 comprises an elastically deformable layer and a low-friction layer, which adheres to the inner circumference of the elastically deformable layer. The low-friction layer, which adheres to the valve core 30, is smooth and has low friction, reducing the motor torque required when the valve core 30 rotates. Sealing ribs 22 are provided on the side of the elastically deformable layer facing the valve housing 10. These ribs extend axially and circumferentially around the through-holes 21 and along the sealing gasket 20. These ribs are serrated, allowing them to undergo significant elastic deformation under pressure. This generates sufficient pressure between the sealing gasket 20 and the valve housing 10, ensuring its conformability to the valve housing 10 and valve core 30. This improves the sealing effectiveness of the sealing gasket 20 and effectively reduces internal leakage within the electronic water valve 01.

[0101] The electronic water valve 01 proposed in the technical solution of the present invention is applied to a thermal management system, which generally serves energy storage (e.g., lithium-ion battery packs), traction motors, other powertrain components, and cabin environment systems. The thermal management system also includes components for cooling the fluid (i.e., radiators or coolers) and / or components for heating the fluid (i.e., heaters). In different systems, the fluid is transported to different components through pathways for various purposes, either heating or cooling. In thermal management systems, one type of system is a thermal system, in which the fluid may be water, a coolant, and / or a refrigerant that is circulated to transfer thermal energy between two or more parts of the system. In different systems, the fluid may be another fluid that is suitable for the current system.
