Description

Technical Field

[0001] This invention relates to the field of vehicle cooling system technology, specifically to a coolant reservoir and a vehicle. Background Technology

[0002] New energy vehicles contain many different hardware components that require cooling. Different hardware components have different optimal operating temperatures and cooling requirements. Therefore, many vehicles require cooling systems with different temperature circuits to operate.

[0003] A coolant reservoir is a device that holds coolant. It is connected to an inlet pipe and an outlet pipe, and is externally connected to cooling pipes that pass through the hardware that needs to be cooled. The coolant circulates between the external cooling pipes and the coolant reservoir, forming a cooling loop and cooling the corresponding external hardware. Because the coolant temperature varies in different cooling loops, traditional OEMs need to fill and manage two or more coolant reservoirs to cool different hardware. Therefore, there is still room for improvement in reducing the number of coolant reservoirs used and optimizing their management. Summary of the Invention

Therefore, they should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "first position" and "second position" refer to two different positions.

[0034] Figure 1 This is a schematic diagram of a coolant reservoir according to an embodiment of the present invention; Figure 2 for Figure 1 A schematic diagram of the upper body of the coolant reservoir shown; Figure 3 for Figure 2 The cross-sectional view of the upper body of the pot shown at point A-A'; Figure 4 for Figure 1 A schematic diagram of the lower body of the coolant reservoir shown.

[0035] like Figures 1-4 As shown, the coolant reservoir includes an upper reservoir body 1, a first partition 2, a lower reservoir body 3, a second partition 4, an inlet pipe 5, a first inlet pipe 6, a first outlet pipe 7, a second inlet pipe 8, and a second outlet pipe 9.

[0036] The upper vessel 1 has a first receiving cavity; the first partition 2 is fixedly connected to the inner wall of the first receiving cavity, dividing the first receiving cavity into a first flow cavity and a second flow cavity; the lower vessel 3 has a second receiving cavity; the second partition 4 is fixedly connected to the inner wall of the second receiving cavity, dividing the second receiving cavity into a third flow cavity and a fourth flow cavity; after the lower vessel 3 and the upper vessel 1 are fixedly connected to each other, the first partition 2 and the second partition 4 abut against each other, and the first flow cavity communicates with the third flow cavity, and the second flow cavity communicates with the fourth flow cavity; the liquid inlet pipe The first end of the inlet pipe 5 is open and connected to a lid. The second end of the inlet pipe 5 is closed and penetrates the upper body 1. The side wall of the inlet pipe 5 is provided with a first outlet 501 and a second outlet 502. The first outlet 501 is connected to the first flow chamber, and the second outlet 502 is connected to the second flow chamber. The first inlet pipe 6 is connected to the first flow chamber or the third flow chamber. The first outlet pipe 7 is connected to the third flow chamber. The second inlet pipe 8 is connected to the second flow chamber or the fourth flow chamber. The second outlet pipe 9 is connected to the fourth flow chamber.

[0037] When filling with coolant, open the reservoir cap and inject coolant into the inlet pipe 5. The coolant enters the inlet pipe 5 and is split at the outlet. It flows through the first outlet 501 into the first flow chamber and the third flow chamber connected to the first flow chamber, and simultaneously through the second outlet 502 into the second flow chamber and the fourth flow chamber connected to the second flow chamber, until the third and fourth flow chambers are full and the coolant level in the first and second flow chambers reaches a set height. Then, stop filling and close the reservoir cap. The first and third flow chambers together form a first reservoir. The first reservoir, the first inlet pipe 6, the first outlet pipe 7, and the connected external cooling pipes together form a first cooling circuit to cool a specific vehicle hardware device. The second and fourth flow chambers together form a second reservoir. The second reservoir, the second inlet pipe 8, the second outlet pipe 9, and the connected external cooling pipes together form a second cooling circuit to cool another vehicle hardware device. The coolant in the two cooling circuits enters different spaces of the same coolant reservoir through the same inlet pipe 5, and circulates independently without interfering with each other, cooling different hardware devices.

[0038] By using the coolant reservoir of this invention, two cooling circuits are integrated into a single coolant reservoir. Coolant is injected into the two cooling circuits through the same inlet pipe, reducing the number of coolant reservoirs required for the entire vehicle, improving the efficiency of coolant filling, reducing the cost of coolant filling equipment and labor, resulting in a lower vehicle space occupancy and reduced load; and making the overall vehicle cooling management more integrated and convenient.

[0039] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, both the upper pot body 1 and the lower pot body 3 are approximately hollow cuboids with rounded corner transitions. Figure 1 The upper vessel 1 has an opening on its lower surface, and the lower vessel 3 has an opening on its upper surface. The two openings are fixedly connected facing each other, and the connection is sealed. The first end of the liquid inlet pipe 5 protrudes from the upper vessel 1, and its second end penetrates the upper vessel 1 at the top. Figure 2 As shown, the first partition 2 is fixedly connected to the inner wall of the first receiving cavity at a position slightly to the right of the center of the upper vessel 1, dividing the first receiving cavity into a first flow cavity on the left and a second flow cavity on the right. The second end of the liquid inlet pipe 5, that is, the end that penetrates into the upper vessel 1, abuts against the first partition 2. Figure 2 , Figure 3 As shown, the first liquid outlet 501 and the second liquid outlet 502 are symmetrically arranged about the central axis of the liquid inlet pipe 5, and the first partition 2 and the central axis of the liquid inlet pipe 5 are located in the same plane. Figure 4 As shown, the second partition 4 is fixedly connected to the inner wall of the second receiving cavity at a position slightly to the right of the center of the lower pot body 3, dividing the second receiving cavity into two parts. Figure 4 The coolant reservoir comprises a third flow chamber in the left half and a fourth flow chamber in the right half. The fixed position of the second partition 4 within the second receiving cavity corresponds to the fixed position of the first partition 2 within the first receiving cavity. After the openings of the upper reservoir 1 and the lower reservoir 3 are fixedly connected facing each other, the first partition 2 and the second partition 4 are completely matched and abut against each other, forming two completely independent parts within the entire coolant reservoir: a first storage tank formed by the communication of the first and third flow chambers, and a second storage tank formed by the communication of the second and fourth flow chambers. Figure 1 , Figure 2 and Figure 4 As shown, the first inlet pipe 6 penetrates the upper reservoir body 1 and communicates with the first flow chamber; the first outlet pipe 7 penetrates the lower reservoir body 3 and communicates with the third flow chamber; the second inlet pipe 8 and the second outlet pipe 9 respectively penetrate the lower reservoir body 3 and communicate with the fourth flow chamber. To facilitate the flow of coolant out of the coolant reservoir, both the first outlet pipe 7 and the second outlet pipe 9 are arranged in... Figure 1 The lowest position of the lower container 3 is described above. Taking the first cooling circuit as an example, when the corresponding vehicle hardware needs to be cooled, the external drive pump is started. The coolant in the first flow chamber and the third flow chamber is discharged through the first outlet pipe 7, flows through the external cooling pipeline, and exchanges heat with the corresponding hardware to cool it down. Finally, the coolant flows back to the first flow chamber and the third flow chamber through the first inlet pipe 6. The hardware to be cooled in the second cooling circuit is different from that in the first cooling circuit, but the working principle is the same, so it will not be described again here. The second cooling circuit and the first cooling circuit can work simultaneously. According to the actual application, the shape and size of the upper container 1 and the lower container 3 can be adjusted. The connection position of the first partition 2 in the first receiving cavity and the connection position of the second partition 4 in the second receiving cavity can be matched and adjusted. The connection position of the inlet pipe 5 with the upper container 1, as well as the connection positions of the first inlet pipe 6, the first outlet pipe 7, the second inlet pipe 8, and the second outlet pipe 9 on the upper container 1 and the lower container 3 can all be adjusted appropriately.

[0040] Optionally, a boss 503 is provided on the inner wall of the second end of the inlet pipe 5. The cross-section of the boss 503 consists of two inclined surfaces facing away from each other, with the two inclined surfaces facing the first outlet 501 and the second outlet 502, respectively. This arrangement reduces the resistance to coolant injection. When coolant is injected through the inlet pipe 5, the coolant will flow out of the first outlet 501 and the second outlet 502 more smoothly and evenly under the diversion effect of the inclined surfaces of the boss 503. Furthermore, the boss 503 helps to resist the impact of coolant during injection and can prevent coolant from flowing through the first outlet 501 and the second outlet 502 when the two cooling circuits are working.

[0041] like Figure 3As shown, in this embodiment, a boss 503 is provided on the inner wall of the second end of the inlet pipe 5, that is, the end that penetrates the upper vessel body 1. The boss 503 is a cone and is symmetrically arranged about the central axis of the inlet pipe 5. The height of the boss 503 is approximately half the height of the first outlet 501 and the second outlet 502. The inclined surface of the cone faces the first outlet 501 and the second outlet 502, respectively. When coolant is injected through the inlet pipe 5, the coolant flows smoothly out of the first outlet 501 and the second outlet 502 along the inclined surface of the boss 503. When the coolant level rises on one side due to expansion, the inclined surface of the boss 503 with a certain height can prevent coolant from entering the other side. Depending on the actual application, the specific size of the boss 503 can be adjusted, or it can be set to other shapes other than a cone, as long as it can guide the coolant to flow smoothly and evenly out of the first outlet 501 and the second outlet 502 respectively, and prevent the coolant from crossing between the two cooling circuits.

[0042] Optionally, the outer wall of the second end of the liquid inlet pipe 5 is provided with reinforcing ribs 25. This arrangement enhances the impact resistance of the liquid inlet pipe 5 and the boss 503.

[0043] like Figure 2 As shown, in this embodiment, a plurality of reinforcing ribs 25 are fixed at intervals on the outer wall of the end of the inlet pipe 5 that penetrates one end of the upper reservoir 1. A plurality of reinforcing ribs 25 may also be fixed inside the upper reservoir 1 and the lower reservoir 3 to increase the strength of the coolant reservoir.

[0044] Optionally, an exhaust valve is installed on the lid; an exhaust hole 504 is provided through the inlet pipe 5; and an exhaust pipe 10 is connected to the exhaust hole 504 outside the upper body 1. With this configuration, if gas is mixed into the coolant or the coolant expands during the operation of the two cooling circuits, causing excessive pressure inside the coolant tank, the exhaust valve on the lid will be opened, and the gas or coolant will be discharged through the first outlet 501, the second outlet 502, the exhaust hole 504, and the exhaust pipe 10 connected to the exhaust hole 504 on the inlet pipe 5. When the pressure inside the coolant tank drops to the normal range, the exhaust valve automatically closes, ensuring stable venting, drainage, and pressure of the entire system.

[0045] like Figure 1 , Figure 3As shown, in this embodiment, the vent 504 is located on the side wall of the inlet pipe 5 that protrudes from the upper vessel body 1, higher than the first outlet 501 and the second outlet 502. The vent pipe 10 communicates with the vent 504 and its opening faces downwards. The pressure values ​​for opening and closing the vent valve can be adjusted according to actual working needs. A commercially available valve that automatically opens and closes based on pressure changes can be used.

[0046] Optionally, at least one first flow divider 11 is provided in the first flow cavity, and the at least one first flow divider 11 divides the first flow cavity into a plurality of first cavities 12; at least one second flow divider 13 is provided in the second flow cavity, and the at least one second flow divider 13 divides the second flow cavity into a plurality of second cavities 14; each of the first flow divider 11 and the second flow divider 13 is provided with an exhaust port 15; at least one third flow divider 16 is provided in the third flow cavity, and the third flow divider 16 corresponds one-to-one with the first flow divider 11 and abuts against each other, dividing the third flow cavity into a plurality of third cavities 17; at least one fourth flow divider 18 is provided in the fourth flow cavity, and the fourth flow divider 18 corresponds one-to-one with the second flow divider 13 and abuts against each other, dividing the fourth flow cavity into a plurality of fourth cavities 19; each of the third flow divider 16 and the fourth flow divider 18 is provided with a through opening 20. In this configuration, when the cooling circuit is in operation, the coolant entering the third flow chamber through the first inlet pipe 6 must sequentially pass through the openings 20 on each of the third diverter plates 16 and flow through each of the third cavities 17 before exiting through the first outlet pipe 7 to continue participating in the cooling cycle. Similarly, the coolant entering the fourth flow chamber through the second inlet pipe 8 must sequentially pass through the openings 20 on each of the fourth diverter plates 18 and flow through each of the fourth cavities 19 before exiting through the second outlet pipe 9 to continue participating in the cooling cycle. This sequential flow of coolant through each cavity increases the coolant's operating flow, thereby enhancing the system's exhaust effect and preventing air intake.

[0047] like Figure 2 As shown, in this embodiment, the left half of the upper vessel body 1 is a first flow cavity. Two perpendicularly intersecting first flow dividers 11 are disposed within the first flow cavity. Each first flow divider 11 has a through-hole 15. The two first flow dividers 11 divide the first flow cavity into four first cavities 12. Figure 4As shown, the left half of the lower vessel 3 is a third flow chamber. Two perpendicularly intersecting third flow dividers 16 are disposed within this third flow chamber. Each third flow divider 16 has a through-hole 20 for coolant to pass through. The two third flow dividers 16 divide the third flow chamber into four third cavities 17. After the upper vessel 1 and the lower vessel 3 are connected facing each other, the first flow divider 11 and the third flow divider 16 abut against each other, so that each first cavity 12 communicates with the corresponding third cavity 17. Figure 2 As shown, the right half of the upper vessel body 1 is a second flow chamber. A second flow divider 13 is horizontally arranged within the second flow chamber, dividing it into upper and lower second cavities 14. The second flow divider 13 also has a through-hole 15. The first cavities 12 and the second cavities 14 within the upper vessel body 1 are connected via the through-holes 15. The first and second flow chambers are connected via the first and second outlets 501 and 502 on the inlet pipe 5, thus ensuring air circulation and consistent air pressure throughout the upper vessel body 1. Figure 4 As shown, the right half of the lower vessel 3 is a fourth flow chamber. Two fourth flow dividers 18 are vertically arranged within this fourth flow chamber. Each fourth flow divider 18 has a through-hole 20 for coolant to pass through. The two fourth flow dividers 18 divide the fourth flow chamber into three fourth cavities 19, including two upper cavities and one lower cavity. After the upper vessel 1 and the lower vessel 3 are connected facing each other, the second flow divider 13 matches and abuts against the fourth flow divider 18, thus... Figure 2 The second cavity 14 in the upper middle part and Figure 4 The fourth cavity 19 in the lower middle part is connected. Figure 2 The second cavity 14 in the lower middle part and Figure 4 The two fourth cavities 19 in the upper middle part are connected. The flow trajectory of the coolant in the third flow cavity and the fourth flow cavity is as follows: Figure 4 As shown, in the third flow chamber, water flows in from the first inlet pipe 6. Figure 2 The coolant in the first cavity 12 in the upper right corner enters the corresponding... Figure 4 Within the third cavity 17 in the lower right corner, the water flows sequentially through the opening 20 on the third diversion plate 16. Figure 4 The third cavity 17, located in the upper right, upper left, and lower left corners, flows out through the first outlet pipe 7, which connects to the lower left third cavity 17, to the external cooling pipeline. After heat exchange with the hardware equipment requiring cooling, it finally flows back into the first cavity 12 through the first inlet pipe 6, and so on. In the fourth flow cavity, the water flows in through the second inlet pipe 8. Figure 4 The fourth cavity 19 in the lower middle part flows through the opening 20 on the fourth diversion plate 18 and passes through the fourth diversion plate 18. Figure 4 The coolant flows from the fourth cavity 19 located in the upper left and upper right corners, and then through the second outlet pipe 9 connected to the fourth cavity 19 in the upper right corner, to the external cooling pipeline. After heat exchange with the hardware equipment requiring cooling, it finally flows back into the fourth cavity 19 through the second inlet pipe 8, and so on. Depending on the actual application, the specific flow path of the coolant in the third flow cavity and the specific flow path in the fourth flow cavity can be adjusted appropriately. The number of the third flow cavity divided into third cavities 17 and the number of the fourth flow cavity divided into fourth cavities 19 can also be adjusted. Correspondingly, the number of the first flow cavity divided into first cavities 12 and the number of the second flow cavity divided into second cavities 14 are also adjusted accordingly.

[0048] Optionally, the coolant reservoir further includes a guide pipe 21, which is disposed inside the upper reservoir body 1, with its first end penetrating the upper reservoir body 1 and its second end extending into the lower reservoir body 3. When the communication position between the first inlet pipe 6 and the first flow chamber is higher than a set height, the first inlet pipe 6 is connected to the first end of the guide pipe 21; or, when the communication position between the second inlet pipe 8 and the second flow chamber is higher than the set height, the second inlet pipe 8 is connected to the first end of the guide pipe 21. If the first inlet pipe 6 or the second inlet pipe 8 penetrates the upper reservoir body 1 and its communication position with the upper reservoir body 1 is higher than the set height, that is, higher than the liquid level after the coolant is filled, the coolant entering the coolant reservoir through the first inlet pipe 6 or the second inlet pipe 8 will entrain air when falling into the coolant reservoir, affecting the cooling effect. The guide pipe 21 is installed so that it passes through the upper container 1 and extends into the coolant in the lower container 3. When the communication position between the first inlet pipe 6 or the second inlet pipe 8 and the upper container 1 is higher than the liquid level of the coolant in the coolant tank, the guide pipe 21 is installed at the corresponding position in the upper container 1 so that the coolant in the first inlet pipe 6 or the second inlet pipe 8 flows into the corresponding flow chamber through the guide pipe 21, thus preventing air entrapment into the cooling circuit.

[0049] like Figure 1 , Figure 2As shown, in this embodiment, the first inlet pipe 6 penetrates the upper vessel 1 and communicates with the first flow cavity. The position of the inlet pipe 6 penetrating the upper vessel 1 is higher than the liquid level in the coolant reservoir after filling. Therefore, a guide pipe 21 is provided in the first flow cavity. The upper end of the guide pipe 21 is connected to the first inlet pipe 6, and the lower end extends into the coolant in the third flow cavity of the lower vessel 3. This allows the coolant in the first inlet pipe 6 to be directly guided into the coolant in the third flow cavity via the guide pipe 21, preventing air entrapment. In this embodiment, the second inlet pipe 8 penetrates the lower vessel 3 and communicates directly with the fourth flow cavity, which is filled with coolant. Therefore, there is no issue of air entrapment, and coolant does not need to be introduced into the second inlet pipe 8 through the guide pipe 21. If the second inlet pipe 8 penetrates the upper container 1 and communicates with the second flow chamber, and the position of penetrating the upper container 1 is higher than the liquid level in the coolant reservoir, then the guide pipe 21 should be installed in the second flow chamber so that one end of the guide pipe 21 is connected to the second inlet pipe 8 and the other end extends into the coolant in the fourth flow chamber of the lower container 3.

[0050] Optionally, a liquid level line 22 is provided on the outer wall of the upper vessel 1. This feature, combined with the transparent material of the vessel body, serves as a real-time liquid level comparison indicator.

[0051] like Figure 1 As shown in this embodiment, a horizontal line is marked on the outer wall of the upper vessel 1, and an arrow is pointed out to indicate the normal liquid level of the coolant. This serves as a warning during coolant filling in the factory and during after-sales maintenance.

[0052] Optionally, a connecting hole 23 is provided on the first partition plate 2. The connecting hole 23 is provided on the first partition plate 2 at the normal liquid level height after the coolant has been filled. The coolant in the first flow chamber and the second flow chamber on both sides of the first partition plate 2 can flow in a limited manner through the connecting hole 23 to balance the liquid level difference that may occur between the two cooling circuits when the coolant is filled.

[0053] like Figure 2 As shown, in this embodiment, the connecting hole 23 is a circular hole with a diameter of 2 mm, and its opening height on the first partition 2 corresponds to the height of the liquid level line 22 set on the outer wall of the upper tank body 1. When adding coolant, if the liquid level on one side of the connecting hole 23 is higher and the liquid level on the other side is lower, under the pressure of the liquid level difference, the coolant on the higher liquid level side will gradually flow to the lower liquid level side through the connecting hole 23 until the coolant levels in the two cooling circuit tanks are the same.

[0054] Optionally, the coolant reservoir further includes a connector 24, which is fixedly connected to the outer wall of the upper reservoir body 1 and / or the lower reservoir body 3. This arrangement facilitates quick connection to the vehicle body when installing the coolant reservoir onto the vehicle body using the connector 24 pre-connected to the outer wall of the reservoir body.

[0055] like Figure 1 As shown, in this embodiment, the outer walls of both the upper pot body 1 and the lower pot body 3 are fixedly connected to the connecting member 24. Depending on the actual application, the connecting member 24 can be configured as a snap-fit ​​or other fastening member, or it can be configured as a bolt fastening mounting hole.

[0056] The present invention also provides a vehicle, including a body and a coolant reservoir as described in any of the above embodiments, wherein the coolant reservoir is fixedly connected to the body.

[0057] The vehicle using this invention integrates two cooling circuits into the same coolant reservoir, and coolant is injected into the two cooling circuits through the same inlet pipe. This reduces the number of coolant reservoirs required for the entire vehicle, improves the efficiency of coolant filling, reduces the cost of coolant filling equipment and labor, results in a lower vehicle space occupancy, and reduces the load. The overall vehicle cooling management is also more integrated and convenient.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
