Description

Technical Field

[0001] This invention relates to a multi-state electronic water outlet combination valve for the thermal management system of electric heavy trucks, belonging to the field of electromagnetic valve technology. Background Technology

[0002] The thermal management system of electric heavy trucks is responsible for creating suitable operating temperatures for core components such as batteries, motors, electronic controls, and passenger compartments. The pipelines that are distributed throughout the vehicle are the "blood vessels" of this system, responsible for regulating the temperature of these components and keeping them within the optimal operating temperature range.

[0003] In the existing technology, the thermal management system of electric heavy trucks requires the use of multiple independent electronic three-way valves and four-way valves to distribute the coolant, which leads to complex pipeline connections, large flow resistance and pressure loss, resulting in reduced system heat exchange efficiency. Moreover, the traditional design scheme usually uses an independent loop design, which leads to problems such as component redundancy and fragmented control logic.

[0004] Patent application number 202111439923.3 discloses a directional control valve core, comprising a core body, the core body including a cylindrical rod portion, at least one sealing lip portion provided on the outer circumference of the rod portion, the rod portion and the sealing lip portion being made of the same metal material, the diameter of the rod portion being smaller than the maximum circumferential diameter of the sealing lip portion; and a sealing layer, the sealing layer being uniformly and seamlessly fixedly covering the outer circumferential surface of the core body, the shape of the sealing layer being matched with the outer shape of the core body, and being made of a low-temperature resistant elastic material. However, although the above-mentioned directional control valve core solves the problems of sealing and durability, it still cannot solve the problems of complex piping connections and redundant components in the thermal management system of electric heavy trucks.

[0005] Therefore, there is a need for a multi-state electronic water outlet combination valve for the thermal management system of electric heavy-duty trucks, which simplifies pipeline connections and solves the problem of component redundancy. Summary of the Invention

[0020] In some embodiments, such as Figures 1-3 As shown in this embodiment, a multi-state electronic water outlet combination valve for an electric heavy-duty truck thermal management system includes: Valve seat 1, wherein the valve seat 1 is provided with mutually parallel: The first flow channel 2 and the second flow channel 3, and the valve seat 1 is further provided with the following in a direction perpendicular to the first flow channel 2: Valve core 4, wherein the valve core 4 is provided with: A first fluid passage group 5 and a second fluid passage group 6 are distributed at intervals along the axial direction of the valve core 4. The valve core 4 is also connected to: Actuator 7, which is used to drive the valve core 4 to rotate around its center line at any fixed angle; Depending on the angle at which the actuator 7 drives the valve core 4 to rotate, the valve core 4 has at least five operating states: In the first working state, liquid from a liquid source enters from the inlet of the first flow channel 2, flows through the valve core 4, and simultaneously flows out from the outlet of the first flow channel 2 and the outlet of the second flow channel 3. In the second working state, liquid from one liquid source flows in from the inlet of the first flow channel 2, flows through the valve core 4 and flows out from the outlet of the first flow channel 2. At the same time, liquid from another liquid source flows in from the inlet of the second flow channel 3, flows through the valve core 4 and flows out from the outlet of the second flow channel 3. In the third working state, liquid from a liquid source flows in from the inlet of the second flow channel 3, flows through the valve core 4, and flows out from the outlet of the second flow channel 3. In the fourth working state, liquid from a liquid source flows in from the inlet of the second flow channel 3, flows through the valve core 4, and simultaneously flows out from the outlet of the first flow channel 2 and the outlet of the second flow channel 3. In the fifth working state, liquid from a liquid source flows in from the inlet of the second flow channel 3, flows through the valve core 4, and flows out from the outlet of the first flow channel 2.

[0021] During use: The inlet of the first flow channel 2 is connected to the hydrothermal pool, the inlet of the second flow channel 3 is connected to the cold liquid pool, and the outlet of the second flow channel 3 is connected to the power battery compartment in sequence through the first one-way valve and the first water pump. The flow direction of the first one-way valve is set to flow from the outlet of the second flow channel 3 to the power battery compartment. The outlet of the first flow channel 2 is connected to the passenger compartment in sequence through the second one-way valve and the second water pump. The flow direction of the second one-way valve is set to flow from the outlet of the first flow channel 2 to the passenger compartment. When the battery temperature is less than or equal to 5 degrees Celsius or the set temperature of the passenger compartment is greater than or equal to 20 degrees Celsius, the actuator 7 drives the valve core 4 to rotate to the first working state. At this time, the hot liquid in the hydrothermal pool flows in from the inlet of the first flow channel 2, and the hot liquid flows out from the outlet of the first flow channel 2 and the outlet of the second flow channel 3, respectively, to the power battery compartment and the passenger compartment to exchange heat and raise the temperature of the two compartments. When the battery temperature is greater than or equal to 32 degrees Celsius or the set temperature of the passenger compartment is greater than or equal to 20 degrees Celsius, the actuator 7 drives the valve core 4 to rotate to the second working state. At this time, the cold liquid in the cold liquid pool flows in from the inlet of the second flow channel 3 and flows out from the outlet of the second flow channel 3, flowing to the power battery compartment to exchange heat with the power battery compartment, thereby reducing the battery temperature. At the same time, the hot liquid in the hot liquid pool flows in from the inlet of the first flow channel 2 and flows out from the outlet of the first flow channel 2, flowing to the passenger compartment to exchange heat with the passenger compartment, thereby increasing the temperature inside the passenger compartment. When the battery temperature is between 25 and 32 degrees Celsius, and the natural cooling source can meet the requirements, the actuator 7 drives the valve core 4 to rotate to the third working state. The cold liquid in the cold liquid pool flows in from the inlet of the second flow channel 3 and flows out from the outlet of the second flow channel 3, flowing to the power battery compartment to exchange heat with the power battery compartment, thereby reducing the battery temperature. When the battery temperature is between 35 and 40 degrees Celsius or the passenger compartment temperature is between 28 and 32 degrees Celsius, i.e. when the passenger compartment requires regular cooling, the natural cold source cannot meet the demand. The actuator 7 drives the valve core 4 to rotate to the fourth working state. At this time, the cold liquid in the cold liquid pool flows in from the inlet of the second flow channel 3 and flows out from the outlet of the first flow channel 2 and the outlet of the second flow channel 3, respectively, to the power battery compartment and the passenger compartment to exchange heat and lower the temperature of the power battery compartment and the passenger compartment. When the battery temperature is less than 25 degrees Celsius and the passenger compartment temperature is set between 25 and 28 degrees Celsius, that is, when the vehicle parking battery has no cooling requirement and the passenger compartment needs slight cooling, the actuator 7 drives the valve core 4 to rotate to the fifth working state. At this time, only the second water pump works, and the cold liquid in the cold liquid pool flows in from the inlet of the second flow channel 3 and flows out from the outlet of the first flow channel 2, flowing to the passenger compartment to exchange heat with the passenger compartment and lower the temperature inside the passenger compartment. Depending on the temperature conditions, the actuator 7 can rotate the valve core 4 to quickly switch the working state to meet different heat exchange requirements. This ensures that the power battery compartment and passenger compartment are always in a comfortable working temperature and the temperature range required by the personnel. The multi-state electronic water outlet combination valve can meet the different water outlet pipeline scheme requirements of the electric heavy truck thermal management system, simplifying pipeline connection and solving the problem of component redundancy. It should be noted that the temperature determination conditions for each working state can be adjusted through a preset program according to actual usage needs.

[0022] In one embodiment, reference is made to Figures 3-6As shown, the fluid passages in the first fluid passage group 5 and the second fluid passage group 6 are evenly distributed circumferentially around the axis of the valve core 4. The interval angle between two adjacent fluid passages in the same fluid passage group is equal to the fixed angle by which the actuator 7 drives the valve core 4 to rotate. A first liquid-closing plate is provided at any fluid passage in the first fluid passage group 5, and a second liquid-closing plate is provided at any fluid passage in the second fluid passage group 6. The first liquid-closing plate and the second liquid-closing plate are offset by one position circumferentially from the axis of the valve core 4.

[0023] In the first working state, the second liquid-blocking plate rotates to the inlet of the second flow channel 3 to block the cold liquid from entering the valve core 4. In the fourth working state, the first liquid-blocking plate rotates to the inlet of the first flow channel 2 to block the hot liquid from entering the valve core 4.

[0024] In one embodiment, reference is made to Figures 4-6 As shown, the first liquid passage group 5 includes: a first liquid passage 501, a second liquid passage 502, a third liquid passage 503, a fourth liquid passage 504, and a fifth liquid passage 505. The first liquid passage 501, the second liquid passage 502, the third liquid passage 503, the fourth liquid passage 504, the fifth liquid passage 505, and the first liquid-closing plate are distributed circumferentially along the valve core 4 and are spaced at equal angles. The second liquid passage 502 and the fifth liquid passage 505 are arranged opposite to each other. The second liquid passage group 6 includes: a sixth liquid passage 601, a seventh liquid passage 602, an eighth liquid passage 603, a ninth liquid passage 604, and a tenth liquid passage 605. The sixth liquid passage 601, the seventh liquid passage 602, the eighth liquid passage 603, the ninth liquid passage 604, and the tenth liquid passage 605 are... The second liquid-sealing plate is distributed circumferentially along the valve core 4 and the interval angles are equal. The seventh liquid hole 602 and the tenth liquid hole 605 are arranged opposite to each other. Any two liquid holes among the first liquid hole 501, the third liquid hole 503, the fourth liquid hole 504, the sixth liquid hole 601, the eighth liquid hole 603 and the ninth liquid hole 604 are interconnected. In the second working state, liquid from one liquid source flows in from the inlet of the first flow channel 2, flows through the second liquid hole 502 and the fifth liquid hole 505 and flows out from the outlet of the first flow channel 2. At the same time, liquid from another liquid source flows in from the inlet of the second flow channel 3, flows through the tenth liquid hole 605 and the seventh liquid hole 602 and flows out from the outlet of the second flow channel 3.

[0025] It should be noted that, referring to Figures 5-6 As shown, an independent flow channel is formed between the second liquid hole 502 and the fifth liquid hole 505 through a pipe fitting, and an independent flow channel is formed between the tenth liquid hole 605 and the seventh liquid hole 602 through a pipe fitting to ensure the independence of the flow between liquids in the second working state. In the first working state, the second liquid shut-off plate rotates to the inlet of the second flow channel 3, and the first water pump and the second water pump work simultaneously, so that the hot liquid in the hydrothermal pool flows into the valve core 4 from the inlet of the first flow channel 2, and flows through the first liquid hole 501 to the fourth liquid hole 504 and the eighth liquid hole 603 at the same time, so that it flows out from the outlet of the first flow channel 2 and the outlet of the second flow channel 3 at the same time. In the second working state, the first water pump and the second water pump work simultaneously, so that the hot liquid in the hydrothermal pool flows into the valve core 4 from the inlet of the first flow channel 2, flows through the second liquid hole 502 to the fifth liquid hole 505, and flows out from the outlet of the first flow channel 2. At the same time, the cold liquid in the cold liquid pool flows into the valve core 4 from the inlet of the second flow channel 3, flows through the tenth liquid hole 605 to the seventh liquid hole 602, and flows out from the outlet of the second flow channel 3. In the third working state, the first liquid shut-off plate rotates to the inlet of the first flow channel 2, and only the first water pump works, so that the cold liquid in the cold liquid pool flows into the valve core 4 from the inlet of the second flow channel 3, and flows through the sixth liquid hole 601 to the ninth liquid hole 604, and flows out from the outlet of the second flow channel 3. In the fourth working state, the first liquid shut-off plate rotates to the inlet of the first flow channel 2, and the first water pump and the second water pump work simultaneously, so that the cold liquid in the cold liquid pool flows into the valve core 4 from the inlet of the second flow channel 3, and flows through the sixth liquid hole 601 to the third liquid hole 503 and the ninth liquid hole 604 at the same time, so that it flows out from the outlet of the first flow channel 2 and the outlet of the second flow channel 3 at the same time. In the fifth working state, the first liquid shut-off plate rotates to the inlet of the first flow channel 2, and only the second water pump works, so that the cold liquid in the cold liquid pool flows into the valve core 4 from the inlet of the second flow channel 3, and flows through the sixth liquid hole 601 to the third liquid hole 503, and flows out from the outlet of the first flow channel 2.

[0026] In one embodiment, reference is made to Figures 3-6 As shown, the first and second liquid-sealing plates are integrally formed with the valve core 4 to improve the sealing performance of the first and second liquid-sealing plates for liquid.

[0027] In one embodiment, reference is made to Figure 3 As shown, the actuator 7 includes a dustproof housing and a stepper motor disposed within the dustproof housing. The output end of the stepper motor is connected to the valve core 4 to drive the valve core 4 to rotate.

[0028] Since the different working states of valve core 4 are determined by its rotation angle, the working states of valve core 4 can be precisely switched by using a stepper motor as actuator 7.

[0029] In one embodiment, reference is made to Figures 1-3 As shown, the outer periphery of the inlet end of the first flow channel 2 is provided with a pleated portion for external pipe connection.

[0030] By setting up an external pipe with pleats, the pipe can be prevented from detaching from the inlet end of the first flow channel 2, thereby improving the stability of the pipe connection. Preferred, refer to Figures 1-3 As shown, the outlet end of the first flow channel 2 and the inlet and outlet ends of the second flow channel 3 can all be configured in the same way to improve the stability of the overall pipeline connection.

[0031] In one embodiment, reference is made to Figures 1-3 As shown, both sides of the valve core 4 are provided with cover plates 8, and each of the cover plates 8 is provided with a connection hole to allow the actuator 7 to be connected to the valve core 4.

[0032] Cover plates 8 are provided on both sides of the valve core 4, making the valve seat 1 and the cover plate 8 a separate design. During installation, the valve core 4 is first placed into the valve seat 1, and then the cover plate 8 is installed and fixed, which facilitates the installation of the valve core 4 while ensuring the sealing of the valve seat 1.

[0033] In one embodiment, reference is made to Figures 1-3 As shown, the cover plate 8 is detachably connected to the valve seat 1.

[0034] The cover plate 8 and the valve seat 1 are designed to be detachably connected, which facilitates the replacement of the valve core 4.

[0035] In one embodiment, reference is made to Figures 1-3 As shown, the valve seat 1 has a threaded hole on the side near the cover plate 8, and the cover plate 8 is connected to the threaded hole on the valve seat 1 by bolts 9.

[0036] By connecting the cover plate 8 to the valve seat 1 with bolts 9, the connection stability can be maintained while the cover plate 8 can be quickly disassembled and assembled, thus improving work efficiency.

[0037] In one embodiment, reference is made to Figures 1-3 As shown, both the threaded holes and the bolts 9 are provided with multiple holes.

[0038] The combination of multiple bolts 9 and threaded holes makes the connection between the cover plate 8 and the valve seat 1 tighter, improving the sealing performance.

[0039] In one embodiment, reference is made to Figures 1-3 As shown, the bolts 9 are distributed at the four corners of the cover plate 8.

[0040] Distributing the bolts 9 at the four corners of the cover plate 8 makes the constraint force of the bolts 9 on the cover plate 8 more even, and makes it fit the valve seat 1 better.

[0041] In addition to the above embodiments, the present invention also includes other embodiments. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of the present invention.
