Description

Technical Field

[0001] The present invention relates to the technical field of new energy batteries, and in particular to a new energy vehicle battery heat dissipation system. Background Art

[0002] Electric vehicle batteries are divided into two categories, storage batteries and fuel cells. Storage batteries are suitable for pure electric vehicles, including 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 will be stored in a centralized manner. Since the batteries need to be cooled during storage, fans and other structures are generally configured to dissipate the heat of the stored batteries. This cooling system is used to dissipate the heat of the batteries.

[0003] When batteries are stored, they are placed in a relatively closed space to prevent dust from falling on the batteries, causing pollution and generating static electricity. Since the closed space generally adopts a slot design, the internal space is fixed, and the battery sizes are different, it is obvious that battery structures of different sizes are difficult to match with slots of fixed sizes. Batteries are prone to shaking in slots that are larger and looser than the battery size, which is not conducive to safe storage of batteries. In addition, when the battery is cooled, the effect of conventional wind cooling is also poor. Summary of the invention

[0004] The purpose of the present invention is to provide a new energy vehicle battery heat dissipation system to solve the problem proposed in the above background technology that when storing batteries, the batteries are placed in a relatively closed space to prevent dust from falling on the batteries, causing pollution and generating static electricity. Since the closed space generally adopts a notch design, the internal space is fixed, and the sizes of batteries are different, it is obvious that battery structures of different sizes are difficult to match with notches of fixed sizes. The batteries are easy to shake in the loose notches that are larger than the battery size, which is not conducive to the safe storage of the batteries. In addition, when the batteries are cooled, the effect of conventional wind cooling is also poor.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new energy vehicle battery cooling system, comprising a rectangular upper seat, a concave insertion cavity opened in the upper seat, an L-shaped support foot fixedly connected to the bottom of the upper seat for supporting the upper seat, a storage seat fixedly connected between the upper seat and the support foot for storing coolant, a liquid cavity opened inside the storage seat, and a pump body for conveying coolant arranged in the liquid cavity, the upper seat is provided with a plug plate and a storage seat fixedly connected to each other near the insertion cavity, an L-shaped plug pin is vertically provided at the concave bottom end wall of the upper seat near the concave insertion cavity, and a fitting opening with the same shape as the plug pin and movably connected is opened at the end wall of the storage seat away from the plug plate, the A front notch is provided on the plug plate, and a rectangular storage cavity for placing battery components is provided in the storage seat. A rotating opening is provided near the center of the storage cavity on the storage seat, and a rotating shaft is provided at the center of the rotating opening and the center of the front notch. A partitioning member is provided near the center of the storage cavity on the plug plate, and the partitioning member rotates through the rotating shaft at the rotating opening and divides the space in the storage cavity. Through holes are symmetrically provided at the end wall of the front notch close to the rotating shaft, and the storage seat is connected to a rotating plate by rotating the rotating shaft near the center of the front notch. A horizontally placed first coil is provided at the upper and lower end walls of the upper seat near the insertion cavity, and a vertically placed second coil is staggered at the left and right end walls of the upper seat near the insertion cavity.

[0006] Preferably, the partitioning member includes a partition plate located in the rotating mouth and rotatably connected to the rotating shaft, screw holes symmetrically arranged on the partition plate, screw heads threadedly connected in the screw holes, a cylindrical limiting column fixed on the screw head, a hexagonal solid head fixed at the top end of the limiting column, and a connecting hole for threading a wire provided at the prismatic end wall of the solid head.

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

[0008] Preferably, two limiting columns are provided, and when the partition plate rotates, it drives the limiting columns to move in a circular motion, so that the limiting columns are close to or away from the left and right end surfaces of the storage cavity.

[0009] Preferably, the guide holes are distributed in a ring shape about the center of the fixed head, and six guide holes are provided. One end of the wire can be passed through and bound at the guide hole, and the other end of the wire passes through the through hole and is grounded, so as to remove static electricity on the storage seat.

[0010] A notch is correspondingly provided at the end wall of the rotary plate, and the size of the notch is larger than the size of the through hole, so that when the rotary plate rotates through the rotating shaft, the notch is opposite to the through hole, and the through hole is opened; when the notch and the through hole are staggered, the through hole is blocked.

[0011] Preferably, guide pipes for reflowing cooling liquid are relatively arranged at the left and right ends of the upper seat, and the guide pipes are symmetrically distributed about the center of the liquid cavity, and the liquid cavity is connected with the pump body and the guide pipes.

[0012] Preferably, the first coils and the second coils are each provided in two groups, and each group is provided with five first coils and four second coils, and each group of the first coils and the second coils are connected in sequence 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 respectively connected to the pump body, so that when the pump body is running, the coolant is drawn into the liquid cavity and transported from bottom to top along the first coil and the second coil in sequence, and finally transported back to the liquid cavity from the guide pipe, forming a coolant circulation passage to cool down the upper seat.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The notch of the present invention is opposite to or offset from the through hole and is used to open and close the through hole. In the open state, a grounding wire can be passed through, and a wire connecting a battery component, such as a charging circuit or a detection circuit, can also be passed through. In the closed state, the through hole is blocked, and the storage cavity can be more tightly sealed, making the storage cavity more tightly sealed, further preventing dust from penetrating into the storage cavity and contaminating and affecting the battery component.

[0016] 2. The two limiting columns of the present invention make circular motion displacement in the storage cavity through the partition plate and the rotating shaft, so that the limiting columns divide the space of the storage cavity into two equal parts on the left and right sides, the size of which can be adjusted with high freedom, so as to store battery components of relatively different sizes, and use the limiting columns to stably place the battery components in the storage cavity for safe storage.

[0017] 3. The first coil and the second coil of the same group of the present invention are circulated around the plug cavity located on the same vertical central axis, and each of the three end faces of the plug cavity is provided with a first coil or a second coil. When the pump body is running, the coolant circulates through the three end faces of the plug cavity, so that the three end faces of the plug cavity are cooled by the cooling liquid, and the cooling effect is better;

[0018] 4. The fitting opening and the latch fitting activity in the present invention make the storage seat more stable when pulled out, and also increase the contact area between the storage seat and the upper seat. Further, the heat transfer between the upper seat and the storage seat is increased, so that the cooling structure on the storage seat can fully cool the battery components on the storage seat.

[0032] The upper seat 1 is provided with a plug board 10 and a storage seat 11 fixedly connected to each other near the insertion cavity 2, and a rectangular storage cavity 13 for placing battery components is opened in the storage seat 11. Each insertion cavity 2 is provided with a plug board 10 and a storage seat 11. The upper seat 1 is vertically provided with an L-shaped plug pin 9 at the concave bottom end wall of the concave insertion cavity 2, and the storage seat 11 is provided with a fitting opening 21 of the same shape as the plug pin 9 and movably connected at the end wall of the side away from the plug board 10. The plug board 10 is pulled out to insert the insertion cavity 2. The storage seat 11 in the upper seat 1 is pulled out to take out the new energy vehicle battery, and 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 opening 21 and the latch 9 fit and move, making the storage seat 11 more stable when pulled out, and also increasing the contact area between the storage seat 11 and the upper seat 1. Further, the heat transfer between the upper seat 1 and the storage seat 11 is increased, so that the cooling structure on the storage seat 11 can fully cool the battery components on the storage seat 11;

[0033] Guide pipes 8 for returning cooling liquid are relatively arranged at the left and right ends of the upper seat 1, and the guide pipes 8 are symmetrically distributed about the center of the liquid cavity 4, and the liquid cavity 4 is connected with the pump body 5 and the guide pipes 8. The upper seat 1 is provided with a horizontally placed first coil 6 at the upper and lower end walls near the insertion cavity 2, and the upper seat 1 is provided with a vertically placed second coil 7 at the left and right end walls near the insertion cavity 2. The first coil 6 and the second coil 7 are arranged in two groups, and each group of the first coil 6 is provided with five, and the second coil 7 is provided with four, and each group of the first coil 6 and the second coil 7 is connected in sequence from bottom to top, and finally connected to the guide pipe 8. The two first coils 6 at the bottom of the upper seat 1 are respectively connected with the pump body 5, so that when the pump body 5 is running, the cooling liquid is drawn into the liquid cavity 4, and transported in sequence from bottom to top along the first coil 6 and the second coil 7, and finally transported back to the liquid cavity 4 from the guide pipe 8, forming a cooling liquid circulation passage, so that the temperature in the upper seat 1 is reduced;

[0034] Specifically, a first coil 6 is arranged on the left and right sides of the bottom end walls of the two bottommost insertion chambers 2, with a total of two first coils 6, where two adjacent ends are respectively connected to the pump body 5, wherein the first coil 6 and the second coil 7 of the same group are circulated around the insertion chamber 2 located on the same vertical central axis, and a first coil 6 or a second coil 7 is arranged on the three end faces of each insertion chamber 2, and the first coil 6 and the second coil 7 of the same group are connected in sequence from bottom to top, and the first coils 6 and the second coils 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 insertion chamber 2, so that the three end faces of the insertion chamber 2 are all cooled by the cooling liquid, and the cooling effect is better;

[0035] A front notch 12 is provided on the plug board 10, a rotating opening 14 is provided at the center of the storage cavity 13 of the storage seat 11, a rotating shaft 15 is provided at the center of the rotating opening 14 and the center of the front notch 12, a partitioning piece is provided at the center of the plug board 10 near the storage cavity 13, the partitioning piece rotates through the rotating shaft 15 at the rotating opening 14 and divides the space in the storage cavity 13, through holes 17 are symmetrically provided at the end wall of the front notch 12 close to the rotating shaft 15, and a rotating plate 16 is connected to the storage seat 11 near the center of the front notch 12 through the rotating shaft 15. After the partitioning piece divides the space in the storage cavity 13, the battery component is put into the storage cavity 13 for storage, and the batteries placed in the storage cavity 13 are stored separately by the partitioning piece, and at the same time, the battery will not be loosened due to the size difference with the storage cavity 13 during storage, and the storage is more stable;

[0036] Specifically, the partition member includes a partition plate 18 located in the rotating port 14 and rotatably connected to the rotating shaft 15, a screw hole 19 symmetrically arranged on the partition plate 18, a screw head 20 threadedly connected in the screw hole 19, a cylindrical limiting column 22 fixed on the screw head 20, a hexagonal column-shaped fixed head 23 fixed at the top end of the limiting column 22, and a guide hole 24 for connecting the wire through the prismatic end wall of the fixed head 23. The partition plate 18 is in the shape of a disc, and two screw holes 19 are provided. The depth of the screw hole 19 is less than the length of the screw head 20, so that the screw head 20 is in the screw hole. When the screw head 20 is screwed in the screw hole 19, the screw head 20 can extend from the bottom of the screw hole 19 to contact with the bottom end wall of the rotating mouth 14 and generate friction, thereby limiting the partition plate 18. The manual limiting column 22 rotates and the screw head 20 is screwed to screw the screw head 20 into the screw hole 19 and extend out. At this time, the screw head 20 contacts the bottom end wall of the rotating mouth 14 to generate friction, limiting the partition plate 18, and the screw head 20 is screwed in the opposite direction to retract the screw head 20 into the screw hole 19, releasing the contact between the screw head 20 and the bottom end wall of the rotating mouth 14, so that the partition plate 18 can rotate around the rotating shaft 15;

[0037] When rotating, two limiting posts 22 are provided, and 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 on the left and right. At this time, the two-part space is the smallest, and smaller-sized 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-part space divided by the limiting posts 22 into the largest, at this time, relatively large-sized battery components can be stored, so that battery components of different sizes can be placed in the storage cavity 13, and 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 guide holes 24 are distributed in a ring shape about the center of the fixed head 23, and there are six guide holes 24. One end of the wire can be passed through and bound at the guide hole 24, and the other end of the wire passes through the through hole 17 and is grounded, which is used to remove static electricity on the storage seat 11. One end of the wire is inserted into any guide hole 24 at the fixed head 23, and then passes through another guide hole 24 at the fixed head 23, and then is tied and tied, so that the metal material of the wire is connected to the metal material of the fixed head 23, and then the other end of the wire is passed through along the through hole 17, and the end is connected to the grounding end, such as the ground, so that the static electricity in the storage cavity 13 is guided and discharged, so that the battery components are relatively safe when stored, and the stored battery components are protected;

[0039] Among them, a notch is correspondingly opened at the end wall of the rotating plate 16, and the size of the notch is larger than the size of the through hole 17, so that when the rotating plate 16 rotates through the rotating shaft 15, the notch is opposite to the through hole 17, and the through hole 17 is opened. At this time, the grounding wire can be connected, and the wire connecting the battery component, such as the charging circuit and the detection circuit, can be connected. When the notch and the through hole 17 are staggered, the through hole 17 is blocked. At this time, the storage cavity 13 can be more tightly sealed, making the storage cavity 13 more tightly sealed, and further preventing dust from penetrating into the storage cavity 13 and polluting and affecting the battery component.

[0040] In summary, when the new energy vehicle battery cooling system is used, the plug plate 10 and the storage seat 11 in the concave plug cavity 2 opened in the upper seat 1 are first pulled out to expose the storage cavity 13, and then the battery is placed in the storage cavity 13, and then the battery is inserted into the storage cavity 13 through the partition plate 18 located in the rotating port 14 and rotatably connected to the rotating shaft 15, the screw holes 19 symmetrically arranged on the partition plate 18, the screw heads 20 threadedly connected in the screw holes 19, the cylindrical limiting columns 22 fixed on the screw heads 20, and the hexagonal column-shaped fixed at the top end of the limiting columns 22. The partitioning member formed by the fixed head 23 and the guide hole 24 for connecting the wires provided at the prismatic end wall of the fixed head 23 regulates the space in the storage cavity 13. Specifically, when the partition plate 18 rotates around the rotating shaft 15, it drives the limiting column 22 to move in a circular motion, so that the limiting column 22 approaches or moves away from the left and right end surfaces of the storage cavity 13. Specifically, when the limiting column 22 approaches the left and right end surfaces of the storage cavity 13, the limiting column 22 divides the space of the storage cavity 13 into two equal parts on the left and right. At this time, the space of the two equal parts is the smallest, and batteries of smaller sizes can be stored. When the limiting column 22 is away from the left and right end surfaces of the storage cavity 13, the space divided into two equal parts by the limiting column 22 is the largest. At this time, relatively large battery components can be stored, so that battery components of different sizes can be placed in the storage cavity 13, and 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 against and limited by the limiting column 22, so that the battery component is stably placed in the storage cavity 13 and stored stably. Then, when the screw head 20 is screwed in the screw hole 19, the screw head 20 It can extend from the bottom of the screw hole 19 to contact with the bottom end wall of the rotating mouth 14 and generate friction, so that the partition plate 18 is limited, the manual limit column 22 is rotated, the screw head 20 is screwed, and the screw head 20 is screwed into the screw hole 19 and extended out. At this time, the screw head 20 contacts the bottom end wall of the rotating mouth 14 to generate friction, limit the partition plate 18, and reversely screw the screw head 20 to retract the screw head 20 into the screw hole 19, release the contact between the screw head 20 and the bottom end wall of the rotating mouth 14, so that the partition plate 18 can rotate around the rotating shaft 15;

[0041] At this time, firstly, one end of the wire is inserted into any one of the guide holes 24 at the fixed head 23, and then passed out from another arbitrary guide hole 24 at the fixed head 23, and then tied and tied, so that the metal material of the wire is connected to the metal material of the fixed head 23, and then the other end of the wire is passed out along the through hole 17, and the end is connected to the grounding end, such as the ground, so that the static electricity in the storage cavity 13 is guided and discharged, so that the battery components are relatively safe when stored, and the stored battery components are protected. The end wall of the rotating plate 16 is correspondingly A notch is provided, and the size of the notch is larger than the size of the through hole 17, so that when the rotating plate 16 rotates through the rotating shaft 15, the notch is opposite to the through hole 17, and the through hole 17 is opened. At this time, a grounding wire or a wire connecting a battery component, such as a charging circuit or a detection circuit, can be passed through. When the notch is staggered from the through hole 17, the through hole 17 is blocked, and at this time, the storage cavity 13 can be more tightly blocked, making the storage cavity 13 more tightly sealed, and further preventing dust from penetrating into the storage cavity 13 and contaminating and affecting the battery component;

[0042] After the battery components are stored in the storage seat 11 and limited, the storage seat 11 is pushed into the insertion cavity 2. At this time, when the pump body 5 is running, the coolant is drawn into the liquid cavity 4, and transported from bottom to top along the first coil 6 and the second coil 7 in sequence, and finally transported back to the liquid cavity 4 from the guide tube 8, forming a coolant circulation passage, so that the temperature inside the upper seat 1 is reduced, and the fitting port 21 and the latch 9 are in contact with each other, so that the storage seat 11 is more stable when being pulled out, and the contact area between the storage seat 11 and the upper seat 1 is also increased. Further, the heat transfer between the upper seat 1 and the storage seat 11 is increased, so that the cooling structure on the storage seat 11 can fully cool the battery components 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 end walls of the two lowest insertion chambers 2, with a total of two first coils 6. Here, two adjacent ends are respectively connected to the pump body 5, wherein the first coil 6 and the second coil 7 in the same group are circulated around the insertion chamber 2 located on the same vertical central axis, and a first coil 6 or a second coil 7 is arranged on the three end faces of each insertion chamber 2. The first coil 6 and the second coil 7 in the same group are connected in sequence from bottom to top, and the first coils 6 and the second coils 7 in 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 insertion chamber 2, so that the three end faces of the insertion chamber 2 are cooled by the cooling liquid, and the cooling effect is better.

[0044] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
