Description

Technical Field

[0001] This utility model relates to the field of automotive thermal management technology, specifically to a valve core and a multi-mode electronic water valve. Background Technology

[0002] Common thermal management systems for new energy vehicles include engine cooling systems, battery temperature control systems, and air conditioning systems. Electronic water valves are a new type of coolant flow regulating valve in these systems. Their main function is to adjust the pipe connections and coolant flow rates in each pipe according to temperature changes in different operating parts, ensuring that each system operates at its optimal temperature to achieve energy conservation, emission reduction, and improved energy utilization.

[0003] To achieve coolant flow control and reversal, existing automotive thermal management systems employ multiple three-way, four-way, and five-way electronic water valves, which are complex to control and have a scattered layout. This results in relatively high investment in technology development, molds, and production lines for these products, and makes it difficult to unify management and performance requirements. Utility Model Content

[0004] To address the existing technical problems, this utility model provides a valve core and a multi-mode electronic water valve that is compatible with three-way, four-way and five-way modes, and can accurately adapt to the liquid circulation control needs in complex scenarios such as engine cooling systems, air conditioning systems and battery thermal management systems of new energy vehicles.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0006] A valve core includes a valve core body with a first partition plate on the valve core body. One end of the first partition plate is connected to a second partition plate and a third partition plate. The first partition plate, the second partition plate, and the third partition plate are generally Y-shaped, and the first partition plate, the second partition plate, and the third partition plate divide the valve core body into a first valve core flow channel, a second valve core flow channel, and a third valve core flow channel. A fourth valve core flow channel is also provided in the middle of the valve core body. The second valve core flow channel and the fourth valve core flow channel are normally open, while the first valve core flow channel, the third valve core flow channel, and the fourth valve core flow channel are normally closed.

[0007] Preferably, the second partition plate and the third partition plate are arranged symmetrically.

[0008] Preferably, both the second partition plate and the third partition plate are formed from multiple arc-shaped structural plates.

[0009] The use of an arc-shaped structural plate can effectively reduce the flow resistance of liquid through the first valve core channel, the second valve core channel, and the third valve core channel.

[0010] Preferably, the second partition plate and the third partition plate are respectively connected to the first partition plate by a first arc structure, and the second partition plate and the third partition plate are connected by a second arc structure.

[0011] The transition connection method using the first and second circular arc structures can further and effectively reduce the flow resistance of liquid through the first, second, and third valve core channels.

[0012] Preferably, the end of the second partition plate away from the first partition plate is bent toward the side of the first valve core flow channel, and the end of the third partition plate away from the first partition plate is bent toward the side of the third valve core flow channel.

[0013] This design effectively reduces the flow resistance of liquid entering the second valve core channel.

[0014] Preferably, the fourth valve core flow channel is positioned on the valve core body at a lower position than the first valve core flow channel, the second valve core flow channel, and the third valve core flow channel are positioned on the valve core body.

[0015] A multi-mode electronic water valve includes a valve body, the valve body having a valve body core, a mounting cavity in the middle of the valve body core, a valve core being installed in the mounting cavity, four first valve body flow channels distributed circumferentially on the valve body core, each of the first valve body flow channels communicating with the mounting cavity through a slot at a corresponding position, and the valve body core also having a second valve body flow channel, the second valve body flow channel being normally connected to the fourth valve core flow channel.

[0016] Preferably, the slot on the valve body is positioned higher than the second valve body flow channel on the valve body.

[0017] Preferably, a sealing gasket is also installed in the mounting cavity, the valve core is located inside the sealing gasket, and two baffles are provided on the cavity wall of the mounting cavity. The two baffles are respectively located on both sides of one of the slots, and the two arms at the notch of the sealing gasket abut against the baffles at the corresponding positions.

[0018] With this configuration, since the first, second, and third partition plates on the valve core are interference-fitted with the inner side of the sealing gasket, a certain amount of friction will be generated between the first, second, and third partition plates and the sealing gasket during the rotation of the valve core. By pressing the notch of the sealing gasket against the two stop bars, the movement of the sealing gasket due to friction during the rotation of the valve core can be effectively prevented.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model can combine the valve core and valve body to form 12 different modes. One multi-mode electronic water valve can replace the existing three-way, four-way and five-way electronic water valves, meet the liquid circulation control needs of complex scenarios such as cooling system, air conditioning system and battery thermal management system of new energy vehicles, simplify the overall vehicle layout and reduce costs.

When the valve core rotates under the action of the actuator 5, the first valve core flow channel 34, the second valve core flow channel 35 and the third valve core flow channel 36 can be connected to different first valve body flow channels 11 on the valve body 1.

[0044] The slot 13 is positioned higher on the valve body 10 than the second valve body flow channel 12. A shaped sealing gasket 6 is provided at the lower end of the valve body 10. The shaped sealing gasket 6 has through holes corresponding to the four first valve body flow channels 11 and the second valve body flow channels 12, facilitating the flow of coolant.
