[0002] The expansion water tank is one of the core components of the automotive cooling system, mainly used to adjust the volume change of the coolant, maintain the stability of the system pressure, and improve the heat dissipation efficiency. In fuel vehicles, usually one expansion water tank is equipped, while in new energy vehicles, due to the independent thermal management of each component, three expansion water tanks can also be set according to the battery, motor and electronic control system. And with the continuous development of new energy vehicle technology, the performance requirements for the expansion water tank are also increasing continuously.

[0003] Although the expansion water tank in the prior art is continuously developing towards lightweight in terms of materials, when the vehicle is moving, the liquid inside the expansion water tank will move continuously with the vehicle. Long-term shaking is likely to cause the expansion water tank to be stressed and cracked, affecting the normal operation of the expansion water tank. Summary of the Invention

[0004] To solve the problem that although the expansion water tank in the prior art is continuously developing towards lightweight in terms of materials, when the vehicle is moving, the liquid inside the expansion water tank will move continuously with the vehicle. Long-term shaking is likely to cause the expansion water tank to be stressed and cracked, affecting the normal operation of the expansion water tank, the present application provides a thickened expansion water tank with a self-cooling diversion pipe, and the specific scheme is as follows.

[0005] A thickened expansion water tank with a self-cooling diversion pipe, comprising a tank body, an inlet pipe and an outlet pipe are arranged on the tank body, the inlet pipe is used for introducing coolant, and the outlet pipe is used for discharging coolant. It is characterized in that: the tank body comprises an upper shell and a lower shell, and the upper shell and the lower shell are detachably connected; A plurality of isolation plates are arranged in the upper shell, and isolation plates are also arranged in the lower shell. A plurality of the isolation plates are arranged at equal intervals along the transverse direction, and the isolation plates are also arranged at equal intervals along the longitudinal direction. The transverse isolation plates and the vertical isolation plates are perpendicular to each other and integrally arranged. The isolation plates in the lower shell and the upper shell are correspondingly arranged. The isolation plates in the lower shell can form independent liquid chambers, and the isolation plates in the upper shell can form independent gas chambers. Through grooves are formed on the adjacent isolation plates, and the through grooves are for the flow of gas and liquid, the outlet pipe; A return air pipe is further arranged on the upper shell, the return air pipe is communicated with the corresponding gas chamber, and the outlet pipe is communicated with the corresponding liquid chamber.

[0006] By adopting the above technical solution, the upper shell and the lower shell of the expansion water kettle are detachably connected, which is convenient for disassembly, cleaning and maintenance. The isolation plate in the upper shell and the lower shell forms independent gas chambers and liquid chambers, which can effectively isolate gas and liquid, prevent mixing, and can also reduce the damage to the expansion water kettle caused by the continuous movement of the liquid in the expansion water kettle, improving the working efficiency of the expansion water kettle. The through grooves on the isolation plate allow gas and liquid to flow through, ensuring the connectivity between the chambers and enabling the coolant to be evenly distributed among the chambers. The return air pipe is connected to the gas chamber, which helps to discharge the gas, ensuring the internal pressure balance of the expansion water kettle. The liquid outlet pipe is connected to the liquid chamber, facilitating the discharge of the coolant.

[0007] Optionally, a diversion pipe is provided at the return air pipe. One end of the diversion pipe is connected to the return air pipe, and the other end of the diversion pipe extends into the liquid chamber of the lower shell.

[0008] By adopting the above technical solution, the setting of the diversion pipe can effectively guide the gas to flow from the return air pipe to the liquid chamber, avoiding the direct entry of high-temperature gas into the upper side of the liquid chamber and causing turbulence or impact on the liquid. The liquid entering the liquid chamber can be directly cooled, reducing the impact on the liquid surface.

[0009] Optionally, a guide plate is provided in the lower shell corresponding to the diversion pipe. The guide plate is arranged corresponding to the shape of the diversion pipe and surrounds the diversion pipe.

[0010] By adopting the above technical solution, the setting of the guide plate can be adapted according to the shape of the diversion pipe, effectively supporting and positioning the diversion pipe, preventing it from shifting or shaking in the lower shell, so as to ensure the smooth flow between the diversion pipe and the liquid chamber. In addition, the abutting design of the guide plate and the diversion pipe further enhances the structural stability, avoiding the change of the position of the diversion pipe caused by external vibration or liquid flow impact, and improving the overall reliability of the expansion water kettle.

[0011] Optionally, a guide plate is also provided in the lower shell corresponding to the liquid outlet pipe. The guide plate and the liquid outlet pipe cooperate to form a diversion space, and the diversion space can guide the liquid to flow into the liquid outlet pipe.

[0012] By adopting the above technical solution, the guide plate provided in the lower shell and the liquid outlet pipe cooperate to form a diversion space, which can effectively guide the liquid to flow into the liquid outlet pipe along a predetermined path, thus avoiding the problems of liquid retention or poor flow in the lower shell, and improving the efficiency and stability of liquid discharge.

[0013] Optionally, a liquid level sensor is further provided on the upper shell. The liquid level sensor is provided with a detection probe facing the lower shell. A relief hole is provided on the isolation plate in the lower shell corresponding to the detection probe. The liquid level sensor is inclined and the detection probe can extend into the relief hole.

[0014] By adopting the above technical solution, the expansion kettle can realize accurate detection of the liquid level. The detection probe of the liquid level sensor extends into the isolation plate in the lower shell through the clearance hole, and the inclined liquid level sensor improves the sensitivity and accuracy of detection. The design of the clearance hole ensures the accurate position of the detection probe and reduces the situation where the detection probe of the liquid level sensor moves and affects the detection accuracy.

[0015] Optionally, a connecting thread is provided at the liquid inlet pipe, and the connecting thread is used for detachably connecting the cover body. A liquid level identification piece is also provided at the position of the kettle body corresponding to the liquid inlet pipe. The liquid level identification piece is slidably connected to the upper shell body, and a support block is provided on the lower shell body corresponding to the liquid level identification piece. The support block can abut against the liquid level identification piece, and the liquid level identification piece is bent and cannot completely block the liquid inlet pipe.

[0016] By adopting the above technical solution, a connecting thread is provided at the liquid inlet pipe of the expansion kettle, which can be conveniently connected to the cover body in a detachable manner, thereby improving the convenience of use. The liquid level indicator is slidably connected to the upper shell body and abutted and limited by the support block on the lower shell body. This design enables the liquid level indicator to move within a certain range, making it easy to observe the liquid level changes. At the same time, its bending setting ensures that the liquid inlet pipe will not be completely blocked, reducing the situation where gas cannot be discharged.

[0017] Optionally, a collecting tank is provided on the upper shell, and the collecting tank is arranged around the liquid inlet pipe, and the collecting tank is used to receive condensed water at the liquid inlet pipe.

[0018] By adopting the above technical solution, the setting of the collection tank can effectively receive the condensed water generated at the liquid inlet pipe, preventing the condensed water from dripping to the outside and causing pollution or safety hazards. Since the collection tank is arranged around the liquid inlet pipe, its structural design is reasonable, and it can collect condensed water in all directions, thereby improving the reliability and practicality of the device.

[0019] Optionally, a drainage groove is further provided in the collecting groove, and the drainage groove is connected to the collecting groove. A drainage tube is also provided on the drainage groove, one end of the drainage tube is connected to the drainage groove, and the other end of the drainage tube is used to discharge liquid.

[0020] By adopting the above technical solution, the condensed water in the collecting tank can be gathered through the drainage tank and discharged through the drainage pipe, which effectively prevents the condensed water from accumulating in the collecting tank, thereby keeping the outside of the expansion kettle dry and clean.

[0021] Optionally, a flow guide plate is arranged in the liquid chamber communicated with the liquid outlet pipe. A guide rail is arranged in the liquid chamber corresponding to the flow guide plate. The flow guide plate is slidably connected with the guide rail. One end of the guide rail faces the liquid outlet pipe. The guide rail passes through the through groove and extends into the adjacent liquid chamber. The flow guide plate can pass through the through groove and enter the adjacent liquid chamber. A driving member for driving the flow guide plate is arranged on the guide rail. A rubber membrane is arranged on the flow guide plate and is fixedly connected with the flow guide plate. A pressure sensor is also arranged on the flow guide plate. The pressure sensor is electrically connected with the driving member. The pressure sensor detects the magnitude and direction of the pressure to drive the flow guide plate.

[0022] By adopting the above technical solutions, the sliding connection design of the flow guide plate and the guide rail makes the flow of liquid between the liquid chambers smoother, effectively avoiding the problem of liquid retention. One end of the guide rail faces the liquid outlet pipe and passes through the through groove and extends into the adjacent liquid chamber, which can guide the flow guide plate to flexibly switch between different chambers, thereby optimizing the flow direction and flow distribution of the liquid. The setting of the driving member realizes the automatic adjustment function of the flow guide plate. The pressure sensor detects the magnitude and direction of the pressure and feeds it back to the driving member, so that the flow guide plate can dynamically adjust its position according to the actual pressure situation, further improving the controllability and efficiency of the liquid flow. And the rubber membrane is used to push the liquid, which can not only increase the thrust by the contraction and restoration of the rubber membrane, but also detect the pressure more intuitively, and can effectively detect the pressure.

[0023] Optionally, the driving member includes a driving spring and two electromagnets. The electromagnets are respectively arranged at both ends of the guide rail. One end of the driving spring is fixedly connected with the electromagnet, and the other end of the driving spring is fixedly connected with the flow guide plate. The electromagnet can adsorb the driving spring to contract.

[0024] By adopting the above technical solutions, the flow guide plate can move flexibly according to actual needs, improving the guiding property and efficiency of the liquid flow. At the same time, the structure is simple and reliable, and it is easy to realize automatic control.

[0025] In summary, the present application has at least the following beneficial effects: The present application solves the problem that although the expansion water kettle in the prior art is continuously developing towards lightweight in terms of materials, when the vehicle is moving, the liquid inside the expansion water kettle will move continuously with the vehicle, and long-term shaking is likely to cause the expansion water kettle to be stressed and cracked, affecting the normal operation of the expansion water kettle. The present application reduces the situation that the liquid affects the kettle body due to large-scale movement inside the kettle body by arranging a plurality of isolation plates inside the kettle body and separating the liquid in each space by the isolation plates.

[0031] The following further details the present application through specific embodiments in conjunction with the accompanying drawings.

[0032] First embodiment A thickened self-cooling and diversion pipe expansion kettle, as Figure 1 and Figure 2 shown, includes a kettle body 1. A liquid inlet pipe 11 and a liquid outlet pipe 12 are arranged on the kettle body 1. The liquid inlet pipe 11 is used for introducing coolant, and the liquid outlet pipe 12 is used for discharging coolant. The kettle body 1 includes an upper shell 13 and a lower shell 14, and the upper shell 13 and the lower shell 14 are detachably connected. Specifically, when implemented, the upper shell 13 and the lower shell 14 can be detachably connected by bolts, and the shapes of the upper shell 13 and the lower shell 14 are correspondingly arranged.

[0033] As Figure 2 and Figure 3As shown, multiple partition plates 2 are provided inside the upper housing 13, and partition plates 2 are also provided inside the lower housing 14. The partition plates 2 are arranged at equal intervals along the horizontal direction, and the partition plates 2 are also arranged at equal intervals along the vertical direction. The horizontal partition plates and the vertical partition plates are arranged perpendicular to each other and integrally. The partition plates 2 inside the lower housing 14 and the upper housing 13 are arranged corresponding to each other. The partition plates 2 inside the lower housing 14 can form independent liquid chambers 22, and the partition plates 2 inside the upper housing 13 can form independent gas chambers 23. Through holes 21 are provided on the adjacent partition plates 2, and the through holes 21 allow gas and liquid to flow through. Specifically, when implemented, the gas chambers 23 allow gas to move, and the liquid chambers 22 allow liquid to flow. The standard liquid level is at the junction of the upper housing 13 and the lower housing 14.

[0034] As Figure 1 and Figure 2 shown, a return air pipe 15 is further provided on the upper housing 13. The return air pipe 15 is communicated with the corresponding gas chamber 23, and the liquid outlet pipe 12 is communicated with the corresponding liquid chamber 22. A diversion pipe 151 is provided at the return air pipe 15. One end of the diversion pipe 151 is connected to the return air pipe 15, and the other end of the diversion pipe 151 extends into the liquid chamber 22 of the lower housing 14.

[0035] A guide plate 16 is provided inside the lower housing 14 corresponding to the diversion pipe 151. The guide plate 16 is arranged corresponding to the shape of the diversion pipe 151, and the guide plate 16 surrounds the diversion pipe 151. Specifically, when implemented, there are two return air pipes 15. The return air pipes 15 can introduce high-temperature gas into the kettle body 1, and introducing high-temperature gas above the liquid surface is likely to cause turbulence or impact. Therefore, the high-temperature gas can be directly introduced into the coolant through the diversion pipe 151 for cooling, thereby reducing the situation where the liquid is disordered due to a sudden increase in temperature.

[0036] As Figure 2 and Figure 3 shown, a guide plate 16 is also provided inside the lower housing 14 corresponding to the liquid outlet pipe 12. The guide plate 16 and the liquid outlet pipe 12 cooperate to form a diversion space 161, and the diversion space 161 can guide the liquid to flow into the liquid outlet pipe 12.

[0037] As Figure 1 and Figure 2 shown, a liquid level sensor 17 is further provided on the upper housing 13. The liquid level sensor faces the lower housing 14 and is provided with a detection probe 171. A relief hole 24 is provided on the partition plate 2 inside the lower housing 14 corresponding to the detection probe 171. The liquid level sensor 17 is inclined and the detection probe 171 can extend into the relief hole 24. Specifically, when implemented, the liquid level sensor 17 is obliquely arranged, and the detection probe 171 of the liquid level sensor 17 extends into the relief hole 24 for liquid level detection.

[0038] As Figure 1As shown in the figure, a connecting thread 111 is provided at the liquid inlet pipe 11. The connecting thread 111 is used for detachably connecting the cover body. At the position of the kettle body 1 corresponding to the liquid inlet pipe 11, a liquid level marking member 131 is further provided. The liquid level marking member 131 is slidably connected to the upper housing 13. A support block 141 is provided at the lower housing 14 corresponding to the liquid level marking member 131. The support block 141 can abut against the liquid level marking member 131. The liquid level marking member 131 is bent and cannot completely block the liquid inlet pipe 11. A collection groove 132 is provided on the upper housing 13. The collection groove 132 is arranged around the liquid inlet pipe 11 and is used for receiving the condensed water at the liquid inlet pipe 11. A drainage groove 133 is further provided in the collection groove 132. The drainage groove 133 is communicated with the collection groove 132. A drainage pipe 134 is provided on the drainage groove 133. One end of the drainage pipe 134 is communicated with the drainage groove 133, and the other end of the drainage pipe 134 is used for discharging the liquid. In specific implementation, part of the gas will flow to the liquid inlet pipe 11 for discharge, and condensed water will be formed due to the temperature difference. At this time, the condensed water can flow and be collected in the collection groove 132, and then the condensed water can enter the drainage groove 133 and be discharged through the drainage pipe 134.

[0039] Working principle: A plurality of isolation plates 2 are arranged inside the kettle body 1. The liquid is separated in each space by the isolation plates 2, so as to reduce the situation that the liquid moves greatly inside the kettle body 1 and collides with the inner wall of the kettle body 1, which affects the kettle body 1, and reduce the damage of the kettle body 1.

[0040] Embodiment 2 As Figure 4 shown, the main difference between Embodiment 2 and Embodiment 1 is that a flow guide plate 3 is provided in the liquid chamber 22 communicated with the liquid outlet pipe 12. A guide rail 31 is provided in the liquid chamber 22 corresponding to the flow guide plate 3. The flow guide plate 3 is slidably connected to the guide rail 31. One end of the guide rail 31 faces the liquid outlet pipe 12. The guide rail 31 extends into the adjacent liquid chamber 22 through the through groove 21. The flow guide plate 3 can enter the adjacent liquid chamber 22 through the through groove 21. A driving member for driving the flow guide plate 3 is provided on the guide rail 31. A rubber membrane 32 is provided on the flow guide plate 3. The rubber membrane 32 is fixedly connected to the flow guide plate 3. A pressure sensor 33 is further provided on the flow guide plate 3. The pressure sensor 33 is electrically connected to the driving member. The pressure sensor 33 detects the pressure magnitude and direction to drive the flow guide plate 3. In specific implementation, the liquid flow rate flowing towards the liquid outlet pipe 12 can be detected by the pressure sensor 33. Whether the flow rate is too large or too small will affect the liquid discharge of the liquid outlet pipe 12. Therefore, the flow rate can be adjusted by the back-and-forth movement of the flow guide plate 3 to make the liquid discharge more stable.

[0041] As Figure 4As shown in the figure, the driving member includes a driving spring 311 and two electromagnets 312. The electromagnets 312 are respectively arranged at both ends of the guide rail 31. One end of the driving spring 311 is fixedly connected to the electromagnet 312, and the other end of the driving spring 311 is fixedly connected to the flow guide plate 3. The electromagnet 312 can adsorb the driving spring 311 to contract. Specifically, when the flow guide plate 3 needs to push the liquid towards one side, the electromagnet 312 on that side is in a repeated start-stop state, so as to realize the pushing of the liquid.

[0042] Working principle: The basic principle is the same as that of the embodiment, but a flow guide plate 3 that can adjust the flow rate according to the real-time pressure is added. Through the flow guide plate 3, the liquid outflow rate of the liquid outlet pipe 12 is kept stable.

[0043] The above is the preferred embodiment of this application. It does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
