Bubble separation structure, thermal management system, and vehicle

Abstract

This application provides a bubble separation structure, a thermal management system, and a vehicle. The bubble separation structure includes a shell. The shell is provided with an inlet, a gas outlet, and a liquid outlet. A flow channel space is provided inside the shell. A separator is provided within the flow channel space. The separator divides the flow channel space into a gas flow channel and a liquid flow channel. In the vertical direction, the gas flow channel is located above the liquid flow channel, and the gas outlet is located above the inlet and the liquid outlet. The gas flow channel connects the inlet and the gas outlet. The liquid flow channel connects the inlet and the liquid outlet. Because the separator divides the flow channel space into a gas flow channel and a liquid flow channel, and the gas flow channel is located above the liquid flow channel, when liquid carrying bubbles enters the bubble separation structure through the inlet, the bubbles rise to the gas flow channel and are promptly discharged through the gas outlet.

Description

Technical Field

[0001] This application relates to the field of thermal management technology, and in particular to a bubble separation structure, a thermal management system, and a vehicle. Background Technology

[0002] With the increasing integration of thermal management systems in new energy vehicles, the three major circulation loops of the vehicle—drive motor, battery pack, and air conditioning—are highly integrated through series and parallel connections, with heat exchange occurring between the loops via flowing coolant. This increased integration necessitates more piping connections between components. Especially after the water pump is integrated into the flow channel plate, bends and dead zones exist in the piping and flow channel plate, causing air contained in the coolant within the thermal management system to circulate and fail to dissipate in a timely manner.

[0003] Residual air within the thermal management system can reduce the heat exchange efficiency of the system's heat exchangers. When air accumulates at the water pump inlet, it can be drawn into the pump, causing it to run dry and preventing it from reaching the required head, thus also reducing the pump's lifespan. Separating air bubbles from the coolant and preventing air from being drawn into the pump are common pain points in new energy vehicles. Utility Model Content

[0004] This application provides a bubble separation structure, a thermal management system, and a vehicle to solve related technical problems.

[0005] This application provides a bubble separation structure, including a shell, which has an inlet, a gas outlet, and a liquid outlet. The shell has an internal flow channel space, within which a separator is disposed, dividing the flow channel space into a gas flow channel and a liquid flow channel. In the height direction, the gas flow channel is located above the liquid flow channel, and the gas outlet is located above the inlet and the liquid outlet. The gas flow channel connects the inlet and the gas outlet; the liquid flow channel connects the inlet and the liquid outlet.

[0006] The bubble separation structure of this application utilizes the buoyancy of the bubbles themselves for gas-liquid separation, achieving a better separation effect. Since the separator divides the flow space into a gas flow channel and a liquid flow channel, with the gas flow channel located above the liquid flow channel, when liquid carrying bubbles enters the bubble separation structure through the inlet, the bubbles rise to the gas flow channel and are promptly discharged through the gas outlet.

[0007] Furthermore, the housing includes a first side plate and a second side plate disposed opposite to each other, and a surrounding plate connecting the first side plate and the second side plate. The inlet is disposed on the surrounding plate, and the gas outlet and the liquid outlet are disposed on the first side plate or the second side plate.

[0008] Because the direction of the inlet is different from that of the gas outlet and the liquid outlet, the liquid needs to change direction during its journey. Due to inertia, the liquid is more likely to maintain its original direction of flow, while the gas is more likely to separate and float with the flow, which further improves the separation effect of the bubble separation structure.

[0009] Furthermore, the surrounding plate includes an upper guide portion, a lower guide portion, and a first end plate and a second end plate respectively connecting the two ends of the upper guide portion and the lower guide portion; the inlet is disposed on the first end plate, and the gas outlet is disposed near the second end plate; in the direction from the inlet to the gas outlet, the separation member extends in the same direction as the upper guide portion.

[0010] Since the separation element and the upper guide section extend in the same direction, the flow of bubbles toward the gas outlet becomes smooth, and the mixed bubbles can be discharged smoothly, thus improving the separation effect of the bubble separation structure.

[0011] Furthermore, in the height direction, the ratio of the distance between the starting position of the separator and the lower guide portion to the length of the first end plate is greater than or equal to 50% and less than or equal to 90%.

[0012] By appropriately positioning the separator, both the bubble separation efficiency and the liquid flow efficiency can be comprehensively improved. When the distance between the separator and the lower guide section is too large, the gap between the separator and the upper guide section is too small, reducing the volume of the gas flow channel and hindering bubble discharge. Conversely, when the distance between the separator and the lower guide section is too small, the volume of the liquid flow channel is reduced, affecting liquid flow and hindering its smoothness.

[0013] Furthermore, the separating element includes a first segment and a second segment, the first segment extending upward in an arc shape from a position near the inlet, and the second segment extending upward in an arc shape from the top of the first segment, the bending directions of the first segment and the second segment being opposite.

[0014] By setting the first and second sections with opposite bending directions, the stability of the bubbles during movement is improved, thus enhancing the separation effect of the bubble separation structure.

[0015] Furthermore, the starting position of the first segment is close to the upper end of the inlet. By placing the starting position of the first segment close to the upper end of the inlet, the interference of the separator on the liquid flow is reduced, thereby improving the efficiency of liquid flow.

[0016] Furthermore, let L be the distance between the starting position of the first segment and the inlet. 31 Let L be the distance between the starting position of the first segment and the liquid outlet. 32 L 31 With L 32The ratio is less than or equal to 30%.

[0017] By properly setting the starting position of the first stage, the separation efficiency of bubbles can be further improved. When the distance between the first stage and the inlet is too large, the movement of bubbles as they enter through the inlet is more chaotic, the guiding process of the separator for the bubbles is not timely, and the bubbles are easily re-mixed into the fluid, resulting in a decrease in the gas-liquid separation rate.

[0018] Furthermore, the second section extends above the liquid outlet; the separator also includes a third section extending from the second section toward the gas outlet; the third section and the housing form a supplementary exhaust channel connecting the liquid outlet and the gas outlet.

[0019] By providing a supplementary exhaust channel above the liquid outlet, the mixed air bubbles in the liquid can be discharged through the supplementary exhaust channel when the liquid flows to the liquid outlet, thereby improving the gas-liquid separation efficiency. On the other hand, if some liquid mixes into the gas channel, this liquid can return to the liquid outlet through the supplementary exhaust channel, thus ensuring the amount of liquid circulating.

[0020] Furthermore, in the height direction, the distance between the end of the third segment and the gas outlet is less than or equal to 30 mm. By reducing the distance between the third segment and the gas outlet, the bubbles guided by the separator can flow to the gas outlet more quickly, thereby improving the separation effect of the bubble separation structure.

[0021] Furthermore, in the height direction, the distance between the end of the third segment and the gas outlet is less than or equal to 10 mm.

[0022] By appropriately setting the distance between the end of the third section and the gas outlet, the separation effect of the bubble separation structure and the amount of liquid in the liquid circulation can be guaranteed. When the distance between the third section and the gas outlet is too large, the guiding effect of the separator on the bubbles is reduced, and some bubbles may not be able to be discharged through the gas outlet after leaving the separator, thus worsening the separation effect of the bubble separation structure.

[0023] Furthermore, the volume ratio of the gas channel to the liquid channel is greater than or equal to 1 / 4 and less than or equal to 1 / 2.

[0024] By appropriately setting the volume ratio of the gas channel to the liquid channel, the separation effect of the bubble separation structure and the normal flow of the liquid can be guaranteed. When the volume ratio is too small, the volume of the gas channel is too small, making it difficult for bubbles to enter the gas channel. When the volume ratio is too large, the volume of the liquid channel is too small, affecting the normal flow of the liquid.

[0025] A second aspect of this application provides a thermal management system including the aforementioned bubble separation structure. Because the bubble separation structure has a good bubble separation effect, the thermal management system of this application has a good heat exchange efficiency.

[0026] A third aspect of this application provides a vehicle including the aforementioned thermal management system. Because the thermal management system of this application has good heat exchange efficiency, the vehicle of this application provides a better driving experience.

Detailed Implementation

[0035] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0036] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0037] like Figure 1 and Figure 2 As shown, a first aspect of this application provides a bubble separation structure, including a shell 10. The shell 10 is provided with an inlet 11, a gas outlet 12, and a liquid outlet 13. A flow channel space 100 is provided inside the shell 10. A separator 20 is provided within the flow channel space 100. The separator 20 divides the flow channel space 100 into a gas flow channel 101 and a liquid flow channel 102.

[0038] In the vertical direction, the gas flow channel 101 is located above the liquid flow channel 102. The gas outlet 12 is located above the inlet 11 and the liquid outlet 13. The gas flow channel 101 connects the inlet 11 and the gas outlet 12. The liquid flow channel 102 connects the inlet 11 and the liquid outlet 13.

[0039] The bubble separation structure of this application utilizes the buoyancy of the bubbles themselves for gas-liquid separation, achieving a better separation effect. Since the separator 20 divides the flow space 100 into a gas flow channel 101 and a liquid flow channel 102, and the gas flow channel 101 is located above the liquid flow channel 102, when liquid carrying bubbles enters the bubble separation structure through the inlet 11, the bubbles will float to the gas flow channel 101 and be discharged in time through the gas outlet 12.

[0040] The volume ratio of gas channel 101 to liquid channel 102 is greater than or equal to 1 / 4 and less than or equal to 1 / 2. Specifically, the volume ratio of gas channel 101 to liquid channel 102 can be 1 / 3. Since air bubbles exist as impurities in the coolant and their content is relatively low, the volume of gas channel 101 is relatively smaller than that of liquid channel 102, ensuring gas discharge while allowing the liquid to flow normally.

[0041] By appropriately setting the volume ratio of gas channel 101 to liquid channel 102, the separation effect of the bubble separation structure and the normal flow of the liquid can be guaranteed. When the volume ratio is too small, the volume of gas channel 101 is too small, making it difficult for bubbles to enter gas channel 101. When the volume ratio is too large, the volume of liquid channel 102 is too small, affecting the normal flow of the liquid.

[0042] The housing 10 includes a first side plate 14, a second side plate 15, and a surrounding plate 16. The first side plate 14 and the second side plate 15 are disposed opposite to each other. The surrounding plate 16 connects the first side plate 14 and the second side plate 15. The surrounding plate 16 is provided with a connector structure 17 for mounting other thermal management components. In one embodiment, an inlet 11 is disposed on the surrounding plate 16. A gas outlet 12 and a liquid outlet 13 are disposed on either the first side plate 14 or the second side plate 15.

[0043] Because the direction of inlet 11 is different from that of gas outlet 12 and liquid outlet 13, the liquid needs to change direction during its flow. Due to inertia, the liquid is more likely to maintain its original flow direction, while the gas is more likely to separate and float with the flow, further improving the separation effect of the bubble separation structure. In other embodiments, the positions of inlet 11, gas outlet 12, and liquid outlet 13 are not limited.

[0044] In one embodiment, the bubble separation structure can be integrally formed by casting or other methods. In other embodiments, the first side plate 14, the surrounding plate 16, and the separator 20 can be integrally formed, and the second side plate 15 can be connected to the surrounding plate 16 by welding or other methods. In this embodiment, the first side plate 14 and the surrounding plate 16 are box-shaped structures, and the second side plate 15 is a cover-shaped structure that seals the opening of the box-shaped structure to form the flow channel space 100.

[0045] The surrounding plate 16 includes an upper guide portion 161, a lower guide portion 162, a first end plate 163, and a second end plate 164. The first end plate 163 connects the lower ends of the upper guide portion 161 and the lower guide portion 162. The second end plate 164 connects the upper ends of the upper guide portion 161 and the lower guide portion 162. An inlet 11 is disposed on the first end plate 163, and a gas outlet 12 is disposed near the second end plate 164. In one embodiment, the separator 20 extends in the same direction as the upper guide portion 161 in the direction from the inlet 11 to the gas outlet 12.

[0046] Since the separation element 20 and the upper guide portion 161 extend in the same direction, the flow of bubbles toward the gas outlet 12 becomes smooth, and the doped bubbles can be discharged smoothly, thus improving the separation effect of the bubble separation structure.

[0047] The separator 20 may include a first segment 21, a second segment 22, and a third segment 23. In one embodiment, the first segment 21 extends upward in an arc shape from a position near the inlet 11. The second segment 22 extends upward in an arc shape from the top of the first segment 21. The first segment 21 and the second segment 22 have opposite curvature directions.

[0048] Specifically, the first segment 21 can be formed by extending counterclockwise. The second segment 22 can be formed by extending clockwise. By setting the first segment 21 and the second segment 22 with opposite bending directions, the stability of the bubble during movement is improved, and the separation effect of the bubble separation structure is enhanced.

[0049] In embodiments where the separating member 20 and the upper guide portion 161 extend in the same direction, the upper guide portion 161 may include a first arc-shaped segment 1611 and a second arc-shaped segment 1612. The first arc-shaped segment 1611 extends in the same direction as the first segment 21, and both may extend in a counterclockwise direction. The second arc-shaped segment 1612 extends in the same direction as the second segment 22, and both may extend in a clockwise direction.

[0050] In one embodiment, in the height direction, the ratio of the distance between the starting position of the separator 20 and the lower guide portion 162 to the length of the first end plate 163 is greater than or equal to 50% and less than or equal to 90%. That is... Figure 2 As shown, the length ratio of L1 to L2 is greater than or equal to 50% and less than or equal to 90%.

[0051] By appropriately positioning the separator 20, both gas separation efficiency and liquid flow efficiency can be comprehensively improved. When the distance between the separator 20 and the lower guide section 162 is too large, the gap between the separator 20 and the upper guide section 161 is too small, reducing the volume of the gas flow channel 101 and hindering bubble discharge. Conversely, when the distance between the separator 20 and the lower guide section 162 is too small, the volume of the liquid flow channel 102 is reduced, affecting liquid flow and hindering its smoothness.

[0052] In one embodiment, the starting position of the first segment 21 is close to the upper end of the inlet 11. By placing the starting position of the first segment 21 close to the upper end of the inlet 11, the interference of the separator 20 on the liquid flow can be reduced, thereby improving the efficiency of the liquid flow.

[0053] In this embodiment, such as Figure 2 As shown, the distance L between the starting position of the first segment 21 and the inlet 11 is... 31 Let L be the distance between the starting position of the first segment 21 and the liquid outlet 13. 32 L 31 With L 32 The ratio is less than or equal to 30%.

[0054] By properly setting the position of the first segment 21, the gas separation effect can be improved. When the distance between the first segment 21 and the inlet 11 is too large, the movement of bubbles as they enter through the inlet 11 is more chaotic, the guiding process of the separator 20 for the bubbles is not timely, and the bubbles are prone to re-enter the fluid, resulting in a decrease in the gas-liquid separation rate. In other embodiments, the specific position of the first segment 21 is not limited.

[0055] Specifically, L 31 The numerical range can be greater than or equal to 1 mm and less than or equal to 5 mm. When the distance between the first segment 21 and the inlet 11 is too small, the inlet of the gas flow channel 101 is too narrow, making it difficult for bubbles to enter the gas flow channel 101, thus weakening the separation effect of the bubble separation structure. In other embodiments, L 31 With L 32 The specific numerical range is not limited.

[0056] In one embodiment, the second segment 22 extends above the liquid outlet 13. A third segment 23 may be formed extending from the second segment 22 toward the gas outlet 12. The third segment 23 and the housing 10 form a supplementary exhaust channel 103. The supplementary exhaust channel 103 connects the gas outlet 12 and the liquid outlet 13.

[0057] By providing a supplementary exhaust channel 103 above the liquid outlet 13, when the liquid flows to the liquid outlet 13, the mixed bubbles can be discharged through the supplementary exhaust channel 103, further improving the separation effect of the bubble separation structure. On the other hand, if some liquid is mixed into the gas channel 101, this part of the liquid can return to the liquid outlet 13 through the supplementary exhaust channel 103, thereby ensuring the amount of liquid circulating.

[0058] The specific structure of the separator 20 is not limited. In other embodiments, the separator 20 may also block the top of the liquid outlet 13 so that the gas channel 101 and the liquid channel 102 are relatively isolated at the end.

[0059] In this embodiment, the upper guide portion 161 may further include a first straight segment 1613, the extension trend of which is the same as that of the third segment 23, both extending in a straight line. The lower guide portion 162 may include a straight segment 1621, a third arc-shaped segment 1622, a protruding segment 1623, and a second straight segment 1624.

[0060] The straight section 1621 is horizontally positioned. The third arc-shaped section 1622 extends from the end of the straight section in a clockwise arc direction. The third arc-shaped section 1622 has the same extending trend as the second section 22 of the separator 20, which can reduce the impact of liquid flow.

[0061] The protruding section 1623 extends counterclockwise along the arc from the top of the third arc-shaped section 1622. The protruding section 1623 protrudes beyond the third arc-shaped section 1622. A protruding region 141 connecting the protruding section 1623 is provided on the first side plate 14. The liquid outlet 13 is located in the protruding region 141, so that the liquid outlet 13 has a large area, which can ensure the liquid flow rate.

[0062] The second straight segment 1624 extends upward from the top of the protruding segment 1623. The second straight segment 1624 has the same extension trend as the third segment 23 of the separator 20, ensuring the smooth operation of the bubbles in the supplementary exhaust channel 103.

[0063] In other embodiments, the specific structural forms of the upper guide portion 161, the lower guide portion 162, and the separator 20 are not limited. The separator 20 can be straight, right-angled broken line, arc, etc. The shapes of the upper guide portion 161 and the lower guide portion 162 can be adapted to the separator 20 to ensure that the gas flow channel 101 and the liquid flow channel 102 are relatively stable and to reduce the impact during the flow process.

[0064] In one embodiment, the distance between the end of the third segment 23 in the height direction and the gas outlet 12 is less than or equal to 30 mm, i.e. Figure 2 The length of L4 is less than or equal to 30mm.

[0065] By reducing the distance between the third section 23 and the gas outlet 12, the bubbles guided by the separator 20 can flow to the gas outlet 12 more quickly, improving the gas-liquid separation efficiency. Specifically, the distance between the end of the third section 23 and the gas outlet 12 can be less than or equal to 10 mm. By reasonably setting the distance between the end of the third section 23 and the gas outlet 12, the separation effect of the bubble separation structure can be improved, and the amount of liquid in circulation can be guaranteed.

[0066] When the distance between the third section 23 and the gas outlet 12 is too large, the guiding effect of the separator 20 on the bubbles is reduced, and some bubbles may not be able to be discharged through the gas outlet 12 after leaving the separator 20, which makes the separation effect of the bubble separation structure worse.

[0067] The distance between the end of the third section 23 and the gas outlet 12 can be greater than or equal to 5 mm. When the distance between the end of the third section 23 and the gas outlet 12 is too small, if some liquid is mixed into the gas flow channel 101, this liquid will be discharged directly through the gas outlet 12 and cannot return to the liquid outlet 13 through the supplementary exhaust flow channel 103, thus reducing the amount of liquid entering the circulation.

[0068] Please refer to the following: Figures 3 to 5 As shown, Figures 3 to 5The simulation results of the bubble separation structure in operation are shown to illustrate the gas movement process within the structure. The lighter-colored areas represent bubbles with higher density.

[0069] In this simulation, the distance between the bottom of the separator 20 and the inlet 11 was 3mm, that is... Figure 2 The L shown 31 The distance is 3mm. The distance between the bottom end of the separator 20 and the liquid outlet 13 is 22mm. That is... Figure 2 The L shown 32 It is 22mm. L 31 With L 32 The ratio is approximately 14%. The distance between the bottom end of the separator 20 and the lower guide portion 162 is 70% of the length of the first end plate 163. Figure 2 The ratio of L1 to L2 shown is 70%. In the height direction, the distance from the top of the separator 20 to the gas outlet 12 is 7 mm, i.e. Figure 2 The length of L4 shown is 7 mm. The volume ratio of gas channel 101 to liquid channel 102 is 1 / 3.

[0070] Under the above simulation conditions, Figures 3 to 5 Simulation results at three different time points are shown. For example... Figure 3 As shown, when the gas-liquid mixture enters through inlet 11, the gas inside moves upward due to buoyancy. Figure 4 As shown, under the guiding effect of the separator 20, bubbles move in the gas flow channel 101, and liquid moves in the liquid flow channel 102. Figure 5 As shown, guided by the separator 20, the bubbles flow to the gas outlet 12, thus achieving gas discharge. The liquid flows to the liquid outlet 13.

[0071] Depend on Figures 3 to 5 It can be seen that during the liquid flow process, after passing through the gas channel 101, the bubbles will mainly concentrate and be discharged from the gas outlet 12, while the gas density near the liquid outlet 13 is lower. Therefore, it can be concluded that the bubble separation structure of this application has a better separation effect.

[0072] The bubble separation structure of this application can be a flow channel plate. Inlet 11 can be used as a coolant inlet. Liquid outlet 13 can be connected to a water pump. Gas outlet 12 can be connected to an expansion tank. In other embodiments, liquid outlet 13 can also be connected to other components besides the water pump.

[0073] A second aspect of this application provides a thermal management system including the aforementioned bubble separation structure. Due to the superior bubble separation effect of the bubble separation structure, the thermal management system of this application exhibits high heat exchange efficiency. The thermal management system of this application can be applied to the thermal management of new energy vehicles, and its specific application scope is not limited.

[0074] A third aspect of this application provides a vehicle including the aforementioned thermal management system. Because the thermal management system of this application has better heat exchange efficiency, the vehicle of this application offers a better driving experience. Specifically, the onboard air conditioner has better cooling or heating effects, the drive motor has better operating performance, and the battery pack has better energy supply efficiency. The vehicle of this application can be a pure electric vehicle or a hybrid vehicle, and the specific type is not limited.

[0075] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
