[0025] The embodiments of this application will be further described below with reference to the accompanying drawings:

[0026] The integrated components of the technical solution of this application can be implemented in various ways. At least one of these implementations can be applied to a vehicle thermal management system, and at least one of these implementations can be applied to other thermal management systems such as a home thermal management system or a commercial thermal management system. The fluid in the fluid management device can be coolant, oil, or other media. The following description uses a fluid management device applied to a vehicle thermal management system as an example, in conjunction with the accompanying drawings.

[0027] Please see Figures 1 to 12As shown. One embodiment of this application provides an integrated component 100, which can be used in a vehicle thermal management system. The integrated component 100 includes a flow channel plate assembly 20, which includes a flow channel portion 21 and a flow channel cavity 211. The flow channel portion 21 forms or is part of the flow channel cavity 211. The flow channel plate assembly 20 includes at least one mounting portion 22, the mounting cavity of which (not shown) communicates with the flow channel cavity 112. The integrated component 100 also includes a fluid management device (not shown), which is fixedly connected or limitedly connected to the flow channel plate assembly 20. The fluid management device includes at least one of an electric valve and an electric pump. The flow channel plate assembly 20 also includes a mating portion, which is sealed to the mounting portion, thereby allowing the fluid management device to communicate with the flow channel cavity 211. Specifically, when the fluid management device includes an electric valve, the electric valve can control the flow rate or on / off state of the coolant in the flow channel cavity 211. When the fluid management device includes an electric pump, at least one of the inlet and outlet of the electric pump can be connected to the corresponding flow channel cavity 211 through a mounting part, and the electric pump can provide power for the flow of coolant. As a specific embodiment, the fluid management device includes an electric pump and an electric valve. The flow channel plate assembly 20 includes an interface portion 23, which is connected to an external pipe. Coolant outside the interface portion 23 can enter the flow channel cavity 211, or coolant inside the flow channel cavity 211 can be transported to the outside of the integrated assembly 100 through the interface portion 23. The direction of gravity of the integrated assembly 100 after installation is defined as the first direction 101. The first direction 101 is perpendicular to both the second direction 102 and the third direction 103. The third direction 103 is perpendicular to the second direction 102. The extension length of the flow channel plate assembly 20 in the third direction 103 is greater than the extension length in the first direction 101. It should be noted that, as mentioned above and below, the length direction of the expansion kettle 10 is parallel to the third direction 103, the width direction of the expansion kettle 10 is parallel to the second direction 102, and the height direction of the expansion kettle 10 is parallel to the first direction 101.

[0028] The integrated component 100 also includes an expansion tank 10, which has a liquid storage chamber 13 and an inlet channel 18. The liquid storage chamber 13 can hold the working medium, and the wall corresponding to the liquid storage chamber 13 includes the tank bottom 17. The expansion tank 10 includes a connecting port (not shown in the figure), which is disposed through the lower tank body 12 and communicates with the flow channel portion 21. The expansion tank 10 is fixedly connected to the flow channel plate assembly 20, specifically, the expansion tank 10 and the flow channel plate assembly 20 are welded together. Welding methods include, but are not limited to, infrared welding, laser welding, and hot plate welding. Integrating the expansion tank into the flow channel plate assembly facilitates the miniaturization of the entire thermal management system.

[0029] The expansion tank 10 includes a vent 14 with a vent cavity 143. The flow channel plate assembly 20 includes a flow channel 21 with a flow channel cavity 211. Specifically, when the expansion tank 10 and the flow channel plate assembly 20 are installed and fixed, the wall corresponding to the flow channel cavity 211 is sealed and fixed to the wall corresponding to the inlet channel 18. It can be understood that... Figure 9 As shown, the inlet channel 18 and the flow channel cavity 211 are merged into a single cavity after installation. The exhaust section 14 also includes an exhaust channel 141, an exhaust hole 142, and a through groove 144. The exhaust cavity 143 is connected to the inlet channel 18 through the exhaust hole 142, and the liquid storage cavity 13 is connected to the exhaust cavity 143 through the through groove 144. The exhaust hole 142 is formed on the wall corresponding to the exhaust channel 141, and the through groove 144 is formed on the wall corresponding to the exhaust channel 141. At least part of the wall corresponding to the exhaust cavity 143 is composed of the exhaust channel 141. It can be understood that the gas-liquid mixture in the inlet channel 18 enters the exhaust cavity 143 through the exhaust hole 142, and the gas-liquid mixture flows in the exhaust channel 141. The exhaust channel 141 facilitates the gas-liquid separation of the gas-liquid mixture, and the separated air and working medium are discharged into the liquid storage cavity 13 through the through groove 144. In this way, it is beneficial to reduce the gas in the working medium, thereby improving the heat exchange capacity of the thermal management system.

[0030] In thermal management systems, the working medium flowing through the flow chamber often generates bubbles due to temperature changes or vehicle vibrations. If these bubbles are not separated, it will affect both the performance of the water pump and the overall heat exchange efficiency of the thermal management system. An expansion tank can vent the working medium from the flow chamber. The inventors discovered that in related solutions, the expansion tank's venting section has multiple flow channels to extend the flow path of the working medium, facilitating gas-liquid separation. However, these multiple channels increase the complexity of the expansion tank's internal structure, leading to increased development costs.

[0031] As one implementation method, please refer to Figures 1 to 12As shown, the integrated assembly 100 includes an expansion tank 10, which has a liquid storage chamber 13 and an inlet channel 18. The expansion tank 10 includes an exhaust section 14, which has an exhaust channel 141. The exhaust channel 141 connects the liquid storage chamber 13 and the inlet channel 18. The exhaust channel 141 includes a first channel 1411 and a second channel 1413. The exhaust section 14 includes a partition 145, which separates the first channel 1411 and the second channel 1413. The first channel 1411 and the inlet channel 18 are connected. 8. The second channel 1413 is connected to the liquid storage chamber 13. The partition 145 includes a connecting channel 1412, which connects the first channel 1411 and the second channel 1413. One end of the connecting channel 1412 is provided with a first vent 1422a, and the other end of the connecting channel 1412 is provided with a second vent 1423a. The first vent 1422a is formed on the wall corresponding to the first channel 1411, and the second vent 1423a is formed on the wall corresponding to the second channel 1413. Specifically, the exhaust channel 141 includes a first channel 1411, a connecting channel 1412, and a second channel 1413. The exhaust port 142 includes a first exhaust port 1421, a second exhaust port 1422, and a third exhaust port 1423. At least a portion of the wall of the first channel 1411 is the same wall as the wall of the flow channel portion 21. The first exhaust port 1421 is formed on the same wall as the first channel 1411 and the flow channel portion 21. The first exhaust port 1421 connects the inlet channel 18 and the exhaust chamber 143. The exhaust chamber 143 includes a first exhaust chamber 1431, a second exhaust chamber 1432, and a third exhaust chamber 1433. At least a portion of the wall corresponding to the first exhaust chamber 1431 is the first channel 1411, and at least a portion of the second exhaust chamber 1432 is the third exhaust chamber 1433. The wall portion corresponding to cavity 1432 is a connecting channel 1412, and the wall portion corresponding to at least a portion of the third exhaust cavity 1433 is a second channel 1413. The wall of at least a portion of the connecting channel 1412 is the same wall as the wall of the first channel 1411. The second exhaust hole 1422 is formed on the same wall of the connecting channel 1412 and the first channel 1411, and the second exhaust hole 1422 connects the first exhaust cavity 1431 and the second exhaust cavity 1432. The wall of at least a portion of the second channel 1413 is the same wall as the wall of the connecting channel 1412, and the third exhaust hole 1423 is formed on the same wall of the second channel 1413 and the connecting channel 1412, and the third exhaust hole 1423 connects the second exhaust cavity 1432 and the third exhaust cavity 1433.Along a direction perpendicular to the first direction 101 of the integrated component 100, the first channel 1411 and the second channel 1413 are spaced apart. A partition 145 is located between the first channel 1411 and the second channel 1413. A first vent 1422a is provided at one end of the connecting channel 1412 near the first channel 1411, and a second vent 1423a is provided at the other end of the connecting channel 1412 near the second channel 1413. The first vent 1422a is formed on the wall corresponding to the first channel 1411, and the second vent 1423a is formed on the wall corresponding to the second channel 1413. It can be understood that at least part of the wall constituting the connecting channel 1412 is the wall of the first channel 1411 and / or the second channel 1413. More specifically, part of the wall constituting the connecting channel 1412 is the wall of the first channel 1411, and part of the wall constituting the connecting channel 1412 is the wall of the second channel 1413. In this way, it is beneficial to simplify the structural design of the venting channel, thereby simplifying the internal structure of the kettle.

[0032] As one implementation method, please refer to Figures 1 to 12 As shown, one end of the partition 145 is connected to the wall corresponding to the first channel 1411, and the other end of the partition 145 is connected to the wall corresponding to the second channel 1413. The partition 145 includes a second exhaust chamber 1432. The wall corresponding to the second exhaust chamber 1432 includes a first side portion 1451 and a second side portion 1452. Along a direction perpendicular to the first direction 101, the first side portion 1451 and the second side portion 1452 are arranged opposite to each other. Specifically, along a third direction 103, the first side portion 1451 and the second side portion 1452 are arranged opposite to each other, with the first side portion 1451 closer to the first channel 1411 than the second side portion 1452. The wall corresponding to the first channel 1411 includes the first side portion 1451, and the wall corresponding to the second channel 1413 includes the second side portion 1452. It can be understood that a portion of the wall corresponding to the second exhaust chamber 1432 is composed of the first channel 1411 and the second channel, the first side portion 1451 is the common wall portion connecting the channel 1412 and the first channel 1411, and the second side portion 1452 is the common wall portion connecting the channel 1412 and the second channel 1413. This approach simplifies the structural design of the exhaust channel.

[0033] like Figure 9 and Figure 12As shown, the exhaust port 142 includes a second exhaust port 1422 and a third exhaust port 1423. The second exhaust port 1422 is connected to the first channel 1411 and the second exhaust chamber 1432. The third exhaust port 1423 is connected to the second channel 1413 and the second exhaust chamber 1432. The second exhaust port 1422 includes a first exhaust outlet 1422a, which is formed on the first side portion 1451. The third exhaust port 1423 includes a second exhaust outlet 1423a, which is formed on the second side portion 1452. Specifically, the second vent 1422 includes a first vent 1422a and a third vent 1422b. Along the third direction 103, the first vent 1422a is closer to the first channel 1411 than the third vent 1422b. The third vent 1423 includes a second vent 1423a and a fourth vent 1423b. Along the third direction 103, the second vent 1423a is closer to the second channel 1413 than the fourth vent 1423b. This design simplifies the structural design of the venting channels, thereby simplifying the internal structure of the kettle.

[0034] like Figure 1 and Figure 2 As shown, the shape of the expansion vessel 10 is not strictly limited; for example, the expansion vessel 10 is generally rectangular. The expansion vessel 10 includes an upper body 11 and a lower body 12, which are fixedly connected or mutually restrictive. Specifically, the expansion vessel 10 includes an upper body 11 and a lower body 12, which are sealed together. At least a portion of the vent 14 is integrally formed with the lower body 12. The upper body 11 and the lower body 12 form at least a portion of the liquid storage cavity 13. The arrangement of the upper body 11 and the lower body 12 facilitates the processing of the expansion vessel 10. The upper body 11 and the lower body 12 can be sealed together by welding or bolts. The upper pot body 11 has a first receiving cavity 112, and the lower pot body 12 has a second receiving cavity 121. The upper pot body 11 has a first end face, and the lower pot body 12 has a second end face. The opening of the first receiving cavity 112 is formed on the first end face, and the opening of the second receiving cavity 121 is formed on the second end face. The first end face and the second end face can be fixed by welding. The openings of the first receiving cavity 112 and the second receiving cavity 121 are at least partially opposite to each other.

[0035] like Figures 3 to 12 As shown, at least a portion of the exhaust portion 14 is located in the lower body 12. Specifically, a portion of the exhaust portion 14 is located in the lower body 12, and a portion of the exhaust portion 14 is located in the upper body 11. The portion of the exhaust portion 14 located in the upper body 11 is sealed to the portion of the exhaust portion 14 located in the lower body 12. This sealing connection means that, in order to prevent the working medium from leaking from the exhaust portion at the connection between the upper and lower bodies, in this embodiment, the upper body 11 and the lower body 12 are welded together in a sealed manner. Specifically, as shown... Figure 4As shown, the upper vessel body 11 includes a sealing portion 111, which is sealed to the exhaust portion 14. More specifically, the sealing portion 111 includes a first sealing portion 1111, a second sealing portion 1112, and a third sealing portion 1113. The first sealing portion 1111, the second sealing portion 1112, and the third sealing portion 1113 are respectively sealed to the corresponding first channel 1411, connecting channel 1412, and second channel 1413. It can be understood that at least a portion of the wall portions corresponding to the first exhaust chamber 1431, the second exhaust chamber 1432, and the third exhaust chamber 1433 are the first sealing portion 1111, the second sealing portion 1112, and the third sealing portion 1113. Of course, as another embodiment, the exhaust portion 14 can also be entirely located in the lower vessel body 12. In this way, it is beneficial to prevent the working medium from leaking from the inside of the exhaust portion.

[0036] As one implementation method, such as Figures 5 to 12 As shown, the expansion pitcher 10 includes a side portion 16 and a bottom portion 17, which are connected. The wall portion corresponding to the liquid storage chamber 13 also includes the side portion 16 and the bottom portion 17. The venting portion 14 is fixedly connected to the side portion 16 and includes a venting channel 141. The venting channel 141 protrudes from the side portion 16 toward the liquid storage chamber 13. The venting channel 141 includes a first channel 1411 and a second channel 1413. The first channel 1411 and the second channel 1413 are arranged parallel to or perpendicular to the side portion 16 of the lower pitcher body 12. Specifically, as shown... Figure 5 As shown, the first channel 1411 and the second channel 1413 protrude from the side portion 16 of the pot along the second direction 102 toward the direction close to the liquid storage chamber 13. The first channel 1411 and the second channel 1413 are arranged side by side along the third direction 103. Of course, in other embodiments, the first channel 1411 and the second channel 1413 can be arranged in other ways. For example, the first channel 1411 can be located on the side portion 16 of the lower pot body 12 in the third direction 103, and the second channel 1413 can be located on the side portion 16 of the lower pot body 12 in the second direction 102. The first channel 1411 and the second channel 1413 are arranged perpendicularly. The exhaust channel 141 includes a connecting channel 1412, which connects the first channel 1411 and the second channel 1413. It can be understood that the working medium flows from the inlet channel 18 through the first channel 1411, the connecting channel 1412 and the second channel 1413 into the liquid storage chamber 13. The flow direction of the working medium changes with the exhaust channel 14, increasing the fluctuation of the working medium. In this way, it is beneficial for the gas in the working medium to be released from the liquid.

[0037] like Figures 5 to 12As shown, the exhaust section 14 also includes an exhaust port 142, which includes a first exhaust port 1421, a second exhaust port 1422, and a third exhaust port 1423. Along the direction of gravity of the integrated component 100, the second exhaust port 1422 and / or the third exhaust port 1423 are higher than the first exhaust port 1421, which facilitates the discharge of separated gas into the liquid storage chamber 13, thereby completing the gas-liquid separation function of the working medium. It should be noted that the direction of gravity of the integrated component 100 mentioned above and below refers to the direction of gravity along which the integrated component 100 is installed, such as the first direction 101 in this embodiment. This method helps to reduce the amount of gas present in the working medium and improves the heat exchange capacity of the thermal management system.

[0038] Furthermore, the vent 142 includes a first vent 1421, which is located on the wall corresponding to the inlet channel 18. The first channel 1411 includes a first bottom 1411a, which is connected to the first side portion 1451. The first bottom 1411a separates the inlet channel 18 and the first channel 1411. The first vent 1421 is formed in the first bottom 1411a and connects the first channel 1411 and the inlet channel. Specifically, as shown... Figure 9 As shown, the first exhaust port 1421 is located on the common wall of the first exhaust chamber 1431 and the inlet channel 18. The first exhaust port 1421 penetrates at least a portion of the common wall of the first exhaust chamber 1431 and the inlet channel 18, and the first exhaust port 1421 connects the common wall of the first exhaust chamber 1431 and the inlet channel 18. Preferably, in the installed state, along the direction of gravity of the integrated assembly 100, for example, Figure 9 In the integrated component 100, in the first direction 101, the first exhaust port 1421 is located on the upper wall of the flow channel portion 21. It is understood that, since the density of air is less than the density of the working medium, along the direction of gravity of the integrated component 100, the air in the flow channel cavity 211 and the inlet channel 18 will flow towards the upper wall of the flow channel portion 21. The location of the first exhaust port 1421 on the upper wall of the wall corresponding to the inlet channel 18 facilitates the discharge of gas from the inlet channel 18. In this way, it is beneficial to reduce the amount of gas in the flow channel component.

[0039] Furthermore, the vent 142 includes a second vent 1422. Along a direction perpendicular to the first direction 101 of the integrated assembly 100, the first channel 1411 is closer to the inlet channel 18 than the connecting channel 1412. The second vent 1422 is located on the wall corresponding to the second vent chamber 1432. Specifically, the second vent 1422 is located on the common wall of the first vent chamber 1431 and the second vent chamber 1432. The second vent 1422 penetrates at least a portion of the common wall of the first vent chamber 1431 and the second vent chamber 1432. The working medium enters the first channel 1411 from the first vent 1421 and then exits the first channel 1411 from the second vent 1422. More specifically, at least a portion of the wall corresponding to the first vent chamber 1431 is formed by the first channel 1411, and the first vent 1421 is formed in the first channel. In the wall portion of channel 1411, the first exhaust chamber 1431 flows through the first exhaust hole 1421 into the inlet channel 18, and the second exhaust hole 1422 is formed in the wall portion shared by the first channel 1411 and the connecting channel 1412. Preferably, along the direction of gravity of the integrated assembly 100, the first exhaust hole 1421 is formed on the bottom wall of the first channel 1411, and the second exhaust hole 1422 is formed on the side wall of the first channel 1411 near the top wall. It can be understood that air in the flow channel cavity 211 enters the first exhaust chamber 1431 through the first exhaust hole 1421, flows from bottom to top in the first channel 1411 along the direction of gravity, and is then discharged through the second exhaust hole 1422. The location of the second exhaust hole 1422 on the side wall of the first channel 1411 near the top wall facilitates air entering the connecting channel 1412 through the second exhaust hole 1422. In this way, the flow direction of the working medium is changed, and the flow time of the working medium is prolonged, which is beneficial for the precipitation of gas in the working medium.

[0040] Furthermore, the exhaust port 142 includes a third exhaust port 1423, which is located on the wall corresponding to the second exhaust chamber 1432. Specifically, the third exhaust port 1423 is located on the common wall of the second exhaust chamber 1432 and the third exhaust chamber 1433. The third exhaust port 1423 penetrates at least part of the common wall of the second exhaust chamber 1432 and the third exhaust chamber 1433. The working medium enters the first channel 1411 from the first exhaust port 1421, then leaves the first channel 1411 through the second exhaust port 1422 and enters the connecting channel 1412, and then leaves the connecting channel 1412 through the third exhaust port 1423 and enters the second channel 1413. More specifically, the second vent 1422 is formed on the common wall of the first channel 1411 and the connecting channel 1412, and the second vent 1422 is formed on the common wall of the connecting channel 1412 and the second channel 1413. Along the direction of gravity of the integrated assembly 100, the height of the third vent 1423 is not lower than the height of the second vent 1422. Preferably, along the direction of gravity of the integrated assembly 100, the first vent 1421 is formed on the bottom wall of the first channel 1411, and the second vent 1422 is formed on the side wall of the first channel 1411 near the top wall. It can be understood that the air in the flow channel cavity 211 enters the first vent cavity 1431 through the first vent 1421. The air flows from bottom to top in the first channel 1411 along the direction of gravity, then flows into the connecting channel 1412 through the second vent 1422, then into the third vent cavity 1433 through the third vent 1423, and finally flows into the liquid storage cavity 13 through the through groove 144. This method changes the flow direction of the working medium and prolongs its flow time, which is beneficial for the release of gas from the working medium.

[0041] As one implementation method, please refer to Figures 5 to 12 As shown, the exhaust section 14 includes a through groove 144, which is formed in the wall corresponding to the second channel 1413. Specifically, the through groove 144 is located in the common wall of the second channel 1413 and the liquid storage chamber 13, and penetrates the common wall of the second channel 1413 and the liquid storage chamber 13. The through groove 144 connects the second channel 1413 and the liquid storage chamber 13. It can be understood that the second channel 1413 and the liquid storage chamber 13 are connected through the through groove 144. When the liquid storage chamber 13 contains a working medium... The second channel 1413 also contains a working medium. When no working medium flows into the exhaust section 14 from the inlet channel 18, the liquid level of the working medium in the storage chamber 13 is flush with the liquid level of the working medium in the third exhaust chamber 1433. When the working medium flows into the exhaust section 14 from the inlet channel 18, the working medium previously present in the second channel 1413 is discharged from the through channel 144 under pressure, and then the newly entering working medium in the second channel 1413 is discharged from the through channel 144. In this way, it is beneficial for the precipitation of gas in the working medium and reduces the occurrence of "boiling" phenomenon of the working medium in the expansion tank.

[0042] More specifically, as an implementation method, such as Figure 10 As shown, along the first direction 101, the wall corresponding to the second channel 1413 extends to the bottom 17 of the container. The end of the second channel 1413 that contacts the bottom 17 of the container is defined as the first end 1413a. The through groove 144 is recessed from the first end 1413a in a direction away from the bottom 17 of the container. Specifically, the through groove 144 is located in the part of the wall corresponding to the second channel 1413 near the bottom 17 of the container. It can be understood that setting the through groove 144 in the part of the wall corresponding to the second channel 1413 near the bottom of the container is beneficial to maximizing the use of the space of the expansion tank 10 and can also avoid the occurrence of "dead water". It is also beneficial to ensure that the old liquid in the expansion tank 10 is completely drained when new coolant is added. Preferably, the first end 1413a abuts against the bottom 17 of the container. It can be understood that the first end 1413a abuts against the bottom 17 of the container, which increases the flow path of the working medium, so as to facilitate the gas-liquid separation of the working medium. Of course, in other embodiments, the first end 1413a may not abut against the bottom 17 of the pot, and there may be a gap between the first end 1413a and the bottom 17 of the pot along the first direction 101, which is beneficial to the simplification of the structure of the exhaust part 14.

[0043] As one implementation, the vent 142 is a circular hole with a diameter ranging from 2mm to 5mm. Preferably, the vent 142 is a circular hole with a diameter of 3mm. Of course, the vent 142 can also be of other shapes. Specifically, the diameter corresponding to the minimum flow cross-sectional area of ​​the first vent 1421 is 2mm-5mm, the diameter corresponding to the minimum flow cross-sectional area of ​​the second vent 1422 is 2mm-5mm, and the diameter corresponding to the minimum flow cross-sectional area of ​​the third vent 1423 is 2mm-5mm. It can be understood that the working medium in the flow channel cavity 211 and the inlet channel 18 is a gas-liquid mixture. The vent 142 serves as the inlet / outlet for the working medium to enter the liquid storage cavity 13 from the inlet channel 18. Controlling the diameter of the vent 142 helps control the flow rate of the working medium in the venting section 14, thereby facilitating the precipitation of gas in the working medium.

[0044] The circulating working medium in the thermal management system is affected by temperature, requiring replenishment. The flow channel plate assembly 20 includes a replenishment section (not shown in the figure), which has a replenishment chamber. One end of the replenishment chamber is connected to the expansion tank 10, and the other end is connected to the flow channel cavity 211. In this embodiment, the thermal management system includes an expansion tank. The working medium in the expansion tank can enter the flow channel plate assembly through the replenishment chamber of the replenishment section to replenish the working medium of the entire thermal management system.

[0045] Furthermore, to further reduce the generation of large air bubbles within the expansion vessel 10, the expansion vessel 10 has a baffle portion 15, which is arranged parallel to the side portion 16 of the vessel and is fixedly connected to the wall portion corresponding to the liquid storage chamber 13. This method further facilitates the separation of large air bubbles into smaller air bubbles, thereby reducing the "boiling" phenomenon of the working medium within the expansion vessel.

[0046] Please see Figures 1 to 12 As shown, the flow channel plate assembly 20 can be made of the same type or a single material, including plastics, metals, rubber, or other materials. These materials can also be a combination of multiple materials, such as plastics and metals. The metals mentioned herein include aluminum and aluminum alloys. The flow channel plate assembly 20 is assembled from multiple components, such as multiple stacked components, which can be fixedly connected by welding. Welding methods include, but are not limited to, laser welding, infrared welding, hot plate welding, or ultrasonic welding.

[0047] The above examples illustrate the principles and implementation methods of the present invention. These embodiments are merely illustrative and intended to aid in understanding the method and core concepts of the present invention. It should be noted that those skilled in the art can make various improvements and modifications to the present invention without departing from its principles, and these improvements and modifications also fall within the scope of protection of the present invention.
