Description

Technical Field

[0001] This invention relates to the field of new energy battery technology, specifically to a new energy vehicle battery heat dissipation system. Background Technology

[0002] Electric vehicle batteries are divided into two main categories: storage batteries and fuel cells. Storage batteries are suitable for pure electric vehicles and include lead-acid batteries, nickel-metal hydride batteries, sodium-sulfur batteries, secondary lithium batteries, air batteries, and ternary lithium batteries. After the batteries are manufactured, they are stored in a centralized manner. Since it is necessary to keep the batteries cool during storage, structures such as fans are usually configured to dissipate heat from the stored batteries. This cooling system is used to dissipate heat from the batteries.

[0003] When storing batteries, they are placed in a relatively enclosed space to prevent dust from falling on them, causing contamination and static electricity. Since the enclosed space is generally designed with a slot and the internal space is fixed, while the size of batteries varies, it is obvious that the structure of batteries of different sizes is difficult to fit into the fixed-size slot. The batteries are prone to shaking in the slot, which is relatively large and loose compared to the battery size, which is not conducive to the safe storage of the batteries. In addition, conventional wind cooling is also less effective when the batteries are cooled down. Summary of the Invention

[0004] The purpose of this invention is to provide a heat dissipation system for new energy vehicle batteries, which solves the problems mentioned in the background art. In existing battery storage, batteries are placed in a relatively sealed space to prevent dust from falling onto the battery, causing pollution and static electricity. Since the sealed space is generally designed with a slot and the internal space is fixed, while the size of batteries varies, it is obvious that it is difficult for battery structures of different sizes to fit into the fixed-size slot. The battery is prone to shaking in the slot, which is relatively large and loose compared to the battery size, which is not conducive to the safe storage of the battery. Furthermore, conventional wind cooling is also ineffective when the battery is cooled.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a new energy vehicle battery cooling system, comprising a rectangular upper seat, a concave cavity within the upper seat, a support foot fixedly connected to the bottom of the upper seat for supporting the L-shaped structure of the upper seat, a reservoir for storing coolant fixedly connected between the upper seat and the support foot, a liquid cavity within the reservoir, and a pump body disposed within the liquid cavity for transporting coolant. The upper seat has a plate and a reservoir fixedly connected to each other near the cavity. An L-shaped pin is vertically positioned on the concave bottom end wall of the upper seat near the cavity. The reservoir has a fitting opening of the same shape as the pin and movably connected to the end wall away from the plate. The insert plate has a front slot, and the storage base has a rectangular storage cavity for placing the battery. The storage base has a rotating opening near the center of the storage cavity. A rotating shaft is provided at the center of the rotating opening and the center of the front slot. The insert plate has a partitioning component near the center of the storage cavity. The partitioning component rotates through the rotating shaft at the rotating opening and divides the space inside the storage cavity. The end wall of the front slot has symmetrical through holes adjacent to the rotating shaft. The storage base is rotatably connected to a rotating plate near the center of the front slot via the rotating shaft. The upper seat has horizontally placed first coils on both the upper and lower end walls near the insertion cavity, and vertically placed second coils are staggered on the left and right end walls near the insertion cavity.

[0006] Preferably, the partition component includes a partition plate located inside the rotating opening and rotatably connected to the rotating shaft, screw holes symmetrically arranged on the partition plate, screw heads threadedly connected inside the screw holes, a cylindrical limiting post fixed on the screw head, a hexagonal prism-shaped fixing head fixed at the top end of the limiting post, and a connecting hole for threading wires through the prismatic end wall of the fixing head.

[0007] Preferably, the partition plate is disc-shaped and has two screw holes. The depth of the screw holes is less than the length of the screw head, so that when the screw head is turned in the screw hole, the screw head extends out from the bottom of the screw hole to contact the bottom wall of the rotating port and generate friction, thereby limiting the partition plate.

[0008] Preferably, there are two limiting posts, and when the partition plate rotates, it causes the limiting posts to move in a circular motion, so that the limiting posts are closer to or further away from the left and right end faces of the storage cavity.

[0009] Preferably, the connecting holes are arranged in a ring around the center of the fixed head, and there are six connecting holes. One end of the wire is passed through and tied at the connecting hole, and the other end of the wire passes through the through hole and is grounded to remove static electricity from the storage base.

[0010] A notch is provided at the end wall of the rotating plate. The size of the notch is larger than that of the through hole. When the rotating plate rotates through the shaft, the notch is opposite to the through hole, and the through hole is opened. When the notch is misaligned with the through hole, the through hole is blocked.

[0011] Preferably, the upper seat has guide pipes for returning coolant at its left and right ends, and the guide pipes are symmetrically distributed about the center of the liquid chamber, and the liquid chamber is connected to the pump body and the guide pipes.

[0012] Preferably, the first and second snake tubes are provided in two sets, with five first snake tubes and four second snake tubes in each set, and the first and second snake tubes in each set are connected sequentially from bottom to top and finally connected to the guide tube.

[0013] Preferably, the two first coils at the bottom of the upper seat are connected to the pump body, so that when the pump body is running, the coolant is drawn from the liquid chamber and transported from bottom to top along the first and second coils, and finally transported back to the liquid chamber through the guide pipe, forming a coolant circulation path and cooling the upper seat.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. The notch and through hole of the present invention are opposite or offset to each other, and are used to open and close the through hole. In the open state, a grounding wire can be passed through, or a wire connected to the battery component can be passed through, such as a charging circuit or a detection circuit. In the closed state, the through hole is blocked, which can more effectively seal the storage cavity, making the storage cavity more airtight and further preventing dust from entering the storage cavity and contaminating and affecting the battery component.

[0016] 2. In this invention, the two limiting posts move in a circular motion within the storage cavity via a partition plate and a rotating shaft, allowing the limiting posts to divide the space of the storage cavity into two equal parts with highly adjustable sizes, thus storing battery components of different relative sizes. The limiting posts also ensure that the battery components are stably placed in the storage cavity for secure storage.

[0017] 3. In this invention, the first and second coils of the same group are circulated around the insertion cavity located on the same vertical central axis, and a first or second coil is arranged on the three end faces of each insertion cavity. When the pump is running, the coolant circulates through the three end faces of the insertion cavity, so that the three end faces of the insertion cavity are cooled by the coolant, resulting in a better cooling effect.

[0018] 4. The fitting port and the pin fitting activity in this invention make the storage base more stable when it is pulled out, and also increase the contact area between the storage base and the upper base. Furthermore, it increases the heat transfer between the upper base and the storage base, so that the cooling structure on the storage base can fully cool down the battery components on the storage base.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0031] Please see Figure 1-8 The present invention provides a technical solution: a new energy vehicle battery cooling system, including a rectangular upper seat 1, a concave cavity 2 opened in the upper seat 1, a support foot 25 fixedly connected to the bottom of the upper seat 1 for supporting the L-shaped shape of the upper seat 1, a storage seat 3 for storing coolant fixedly connected between the upper seat 1 and the support foot 25, a liquid cavity 4 opened inside the storage seat 3, and a pump body 5 for conveying coolant disposed in the liquid cavity 4. The cavity 2 is provided in multiple ways. Preferably, the cavity 2 is provided in two groups of four, for a total of eight, and the groups are symmetrically arranged about the center of the upper seat 1.

[0032] The upper seat 1 has a plug plate 10 and a storage seat 11 fixedly connected to each other near the insertion cavity 2. The storage seat 11 has a rectangular storage cavity 13 for placing the battery. Each insertion cavity 2 has one plug plate 10 and one storage seat 11. An L-shaped pin 9 is vertically provided on the concave bottom end wall of the upper seat 1 near the concave insertion cavity 2. The storage seat 11 has a fitting opening 21 of the same shape as the pin 9 and movably connected on the end wall away from the plug plate 10. Pulling out the plug plate 10 opens the insertion cavity 2. The storage seat 11 is pulled out to retrieve and store the new energy vehicle battery. The storage seat 11 is pushed into the insertion cavity 2, so that the battery is placed in the insertion cavity 2. During the pulling and pushing process, the fitting port 21 and the pin 9 fit together, making the storage seat 11 more stable when pulled out. At the same time, it also increases the contact area between the storage seat 11 and the upper seat 1. Furthermore, it increases the heat transfer between the upper seat 1 and the storage seat 11, so that the cooling structure on the storage seat 11 can fully cool the battery components on the storage seat 11.

[0033] The upper seat 1 has guide pipes 8 for returning coolant at its left and right ends, and the guide pipes 8 are symmetrically distributed about the center of the liquid chamber 4. The liquid chamber 4 is connected to the pump body 5 and the guide pipes 8. The upper seat 1 has horizontally placed first coil tubes 6 near the upper and lower end walls of the insertion cavity 2, and vertically placed second coil tubes 7 are staggered near the left and right end walls of the upper seat 1 near the insertion cavity 2. There are two sets of first coil tubes 6 and second coil tubes 7, and each set has five first coil tubes 6 and four second coil tubes 7. The first coil tubes 6 and second coil tubes 7 in each set are connected from bottom to top and finally connected to the guide pipes 8. The two first coil tubes 6 at the bottom of the upper seat 1 are connected to the pump body 5. When the pump body 5 is running, it draws coolant from the liquid chamber 4 and delivers it from bottom to top along the first coil tubes 6 and second coil tubes 7. Finally, it is delivered back to the liquid chamber 4 through the guide pipes 8, forming a coolant circulation path and cooling the upper seat 1.

[0034] Specifically, a first coiled tube 6 is arranged on the left and right sides of the bottom wall of the two bottommost cavities 2, for a total of two first coiled tubes 6. The two adjacent ends are connected to the pump body 5. The first coiled tubes 6 and second coiled tubes 7 of the same group are distributed in a circular manner around the cavities 2 located on the same vertical central axis, and each cavity 2 has a first coiled tube 6 or a second coiled tube 7 arranged on each of the three end faces. The first coiled tubes 6 and second coiled tubes 7 of the same group are connected sequentially from bottom to top. The first coiled tubes 6 and second coiled tubes 7 of different groups are not connected without passing through the pump body 5. When the pump body 5 is running, the coolant circulates through the three end faces of the cavities 2, so that all three end faces of the cavities 2 are cooled by the coolant, resulting in better cooling effect.

[0035] The insert plate 10 has a front slot 12, and the storage base 11 has a rotating port 14 near the center of the storage cavity 13. A rotating shaft 15 is provided at the center of the rotating port 14 and the center of the front slot 12. A partition is provided near the center of the storage cavity 13 on the insert plate 10. The partition rotates through the rotating shaft 15 at the rotating port 14 to divide the space inside the storage cavity 13. A through hole 17 is symmetrically provided on the end wall of the front slot 12 adjacent to the rotating shaft 15. A rotating plate 16 is rotatably connected to the storage base 11 near the center of the front slot 12 through the rotating shaft 15. After the partition divides the space in the storage cavity 13, the battery is put into the storage cavity 13 for storage. The partition separates the batteries placed in the storage cavity 13 for storage, and also prevents the batteries from becoming loose due to the size difference between them and the storage cavity 13, making the storage more stable.

[0036] Specifically, the partition component includes a partition plate 18 located within the rotating opening 14 and rotatably connected to the rotating shaft 15, symmetrically arranged screw holes 19 on the partition plate 18, a screw head 20 threadedly connected within the screw holes 19, a cylindrical limiting post 22 fixed on the screw head 20, a hexagonal prism-shaped fixed head 23 fixed at the top end of the limiting post 22, and a connecting hole 24 for threading wires through the prismatic end wall of the fixed head 23. The partition plate 18 is disc-shaped, and there are two screw holes 19. The depth of the screw holes 19 is less than the length of the screw head 20, so that the screw head 20... When screwed into the hole 19, the screw head 20 extends out from the bottom of the screw hole 19 to contact the bottom wall of the rotating opening 14 and generate friction, thereby limiting the partition plate 18. The manual control limit post 22 is rotated, and the screw head 20 is screwed into the screw hole 19 and extends out. At this time, the screw head 20 contacts the bottom wall of the rotating opening 14 and generates friction, limiting the partition plate 18. The screw head 20 is screwed in the opposite direction to retract into the screw hole 19, releasing the contact between the screw head 20 and the bottom wall of the rotating opening 14, so that the partition plate 18 can rotate around the rotating shaft 15.

[0037] When rotating, there are two limiting posts 22. When the partition plate 18 rotates around the rotating shaft 15, it drives the limiting posts 22 to move in a circular motion, so that the limiting posts 22 are close to or away from the left and right end faces of the storage cavity 13. Specifically, when the limiting posts 22 are close to the left and right end faces of the storage cavity 13, the limiting posts 22 divide the space of the storage cavity 13 into two equal parts. At this time, the two equal parts of the space are the smallest, and smaller battery components can be stored. When the limiting posts 22 are away from the left and right end faces of the storage cavity 13, the two equal parts of the space divided by the limiting posts 22 are the largest. At this time, relatively larger battery components can be stored. Battery components of different sizes can be placed in the storage cavity 13. One side wall of the battery component is in contact with the side wall of the storage cavity 13, and the other side wall of the battery component is abutted and limited by the limiting posts 22, so that the battery component is stably placed in the storage cavity 13 and stored safely.

[0038] The connecting holes 24 are arranged in a ring around the center of the fixed head 23, and there are six connecting holes 24. One end of the wire is passed through and tied at the connecting holes 24. The other end of the wire passes through the through hole 17 and is grounded to remove static electricity from the storage base 11. One end of the wire can be randomly selected to pass through one of the connecting holes 24 at the fixed head 23, and then pass through another random connecting hole 24 at the fixed head 23. After that, it is tied and bound so that the metal material of the wire is connected to the metal material of the fixed head 23. Then, the other end of the wire is passed through the through hole 17 and connected to the grounding terminal, such as the ground, so that the static electricity in the storage cavity 13 is guided out, making the battery relatively safe to store and protecting the stored battery.

[0039] The rotating plate 16 has a notch at its end wall, which is larger than the through hole 17. When the rotating plate 16 rotates through the shaft 15, the notch and the through hole 17 are aligned, and the through hole 17 is opened. At this time, a grounding wire or a wire connecting the battery can be passed through, such as a charging circuit or a testing circuit. When the notch and the through hole 17 are misaligned, the through hole 17 is blocked, which can more effectively seal the storage cavity 13, making the storage cavity 13 more airtight and further preventing dust from entering the storage cavity 13 and contaminating and affecting the battery.

[0040] In summary, when using this new energy vehicle battery cooling system, first pull out the insert plate 10 and the storage seat 11 from the concave insertion cavity 2 inside the upper seat 1 to expose the storage cavity 13. Then, place the battery component into the storage cavity 13. Next, the system is powered by a partition plate 18 located inside the rotating opening 14 and rotatably connected to the rotating shaft 15, symmetrically arranged screw holes 19 on the partition plate 18, a screw head 20 threaded into the screw holes 19, a cylindrical limiting post 22 fixed on the screw head 20, and a hexagonal prism-shaped... The partitioning mechanism formed by the fixed head 23 and the connecting holes 24 for connecting wires through the prismatic end walls of the fixed head 23 regulates the space within the storage cavity 13. Specifically, when the partition plate 18 rotates around the rotating shaft 15, it causes the limiting post 22 to move in a circular motion, allowing the limiting post 22 to move closer to or away from the left and right end faces of the storage cavity 13. Specifically, when the limiting post 22 is close to the left and right end faces of the storage cavity 13, the limiting post 22 divides the space of the storage cavity 13 into two equal parts, at which point the two equal parts are at their minimum size, which can store smaller electrical components. When the limiting post 22 is far away from the left and right end faces of the storage cavity 13, the limiting post 22 divides the storage cavity 13 into two equal spaces, which is the largest. At this time, relatively large battery components can be stored, allowing battery components of different sizes to be placed in the storage cavity 13. One side wall of the battery component is in contact with the side wall of the storage cavity 13, while the other side wall of the battery component is abutted and limited by the limiting post 22, so that the battery component is stably placed in the storage cavity 13 and stored securely. Then, when the screw head 20 is turned in the screw hole 19, the screw head 20... 0 extends from the bottom of the screw hole 19 to contact the bottom wall of the rotating opening 14 and generate friction, thereby limiting the partition plate 18. The manual control limit post 22 rotates and the screw head 20 is turned so that the screw head 20 is screwed into the screw hole 19 and extends out. At this time, the screw head 20 contacts the bottom wall of the rotating opening 14 and generates friction, limiting the partition plate 18. The screw head 20 is turned in the opposite direction so that the screw head 20 is retracted into the screw hole 19, releasing the contact between the screw head 20 and the bottom wall of the rotating opening 14, so that the partition plate 18 can rotate around the rotating shaft 15.

[0041] At this point, first, insert one end of the wire into any one of the connecting holes 24 at the fixed end 23, and then exit through another arbitrary connecting hole 24 at the fixed end 23. Then, tie a knot to connect the metal of the wire to the metal of the fixed end 23. Next, insert the other end of the wire through the through hole 17 and connect this end to the grounding terminal, such as the ground, so that static electricity in the storage cavity 13 is discharged, making the battery relatively safe to store and protecting the stored battery. The end wall of the rotating plate 16 is correspondingly... An opening is provided, the size of which is larger than that of the through hole 17. When the rotating plate 16 rotates through the rotating shaft 15, the opening is opposite to the through hole 17, and the through hole 17 is opened. At this time, a grounding wire or a wire connecting the battery can be passed through, such as a charging circuit or a detection circuit. When the opening is misaligned with the through hole 17, the through hole 17 is blocked. At this time, the storage cavity 13 is sealed more tightly, making the storage cavity 13 more airtight and further preventing dust from entering the storage cavity 13 and contaminating and affecting the battery.

[0042] After the battery is stored in the storage seat 11 and positioned, the storage seat 11 is pushed into the insertion cavity 2. At this time, the pump body 5 runs and draws the coolant from the liquid cavity 4, and delivers it from bottom to top along the first coil 6 and the second coil 7. Finally, it is delivered back to the liquid cavity 4 through the guide pipe 8, forming a coolant circulation path, which cools the upper seat 1. The fitting port 21 and the pin 9 are in contact, making the storage seat 11 more stable when pulled out. At the same time, it increases the contact area between the storage seat 11 and the upper seat 1, further increasing the heat transfer between the upper seat 1 and the storage seat 11, so that the cooling structure on the storage seat 11 can fully cool the battery on the storage seat 11.

[0043] Specifically, in the entire cooling structure, a first coil 6 is arranged on the left and right sides of the bottom wall of the two bottommost cavities 2, for a total of two first coil 6. The two adjacent ends are connected to the pump body 5. The first coil 6 and second coil 7 of the same group are distributed in a circular pattern around the cavities 2 located on the same vertical central axis, and each of the three end faces of the cavities 2 is provided with a first coil 6 or a second coil 7. The first coil 6 and second coil 7 of the same group are connected sequentially from bottom to top. The first coil 6 and second coil 7 of different groups are not connected without passing through the pump body 5. When the pump body 5 is running, the coolant circulates through the three end faces of the cavities 2, so that all three end faces of the cavities 2 are cooled by the coolant, resulting in a better cooling effect.

[0044] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
