Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of battery assembly, in particular to a flow-promoting circulation temperature regulating type battery pack assembly. BACKGROUND

[0002] The flow-promoting circulation temperature regulating type battery pack assembly is a component for battery pack temperature management, which realizes temperature regulation of the battery pack by promoting the circulation flow of the cooling medium to ensure that the battery works in a suitable temperature range and improves the performance and life of the battery.

[0003] A cooling device for a lithium battery and a lithium battery pack, as disclosed in Chinese Patent No. CN108923098B, includes a shell, the upper and lower ends of the shell are respectively clamped with upper and lower clamping plates, and the inner cavity of the shell is divided into a battery mounting cavity and a heat dissipation cavity, the left end of the battery mounting cavity is inserted into an air inlet pipe, and the right end of the battery mounting cavity is inserted into an air outlet pipe, the battery mounting groove is uniformly provided with a battery mounting groove, and the lithium battery is fixedly installed in the battery mounting groove, the air cooling device tightly adheres to the cold plate on the left and right sides of the lithium battery, and the aluminum cold plate with a thickness of one millimeter is used to dissipate heat from the single lithium battery, ensuring the heat dissipation performance of the single lithium battery. At the same time, the air deflector is arranged in the battery mounting cavity, the cooling air entering from the air inlet pipe is guided by the air deflector, and then discharged through the air outlet pipe. The staggered arrangement of the air inlet pipe and the air outlet pipe ensures that the cooling air can fully circulate between the single lithium batteries, and the battery pack is cooled.

[0004] In the prior art cited document, the battery pack is placed in a closed space composed of the shell, the upper clamping plate and the lower clamping plate, which makes it difficult to dissipate heat, resulting in residual heat in the closed space, affecting the heat dissipation and temperature regulation of the battery pack. SUMMARY

[0005] To solve the above technical problems, the present application is realized by the following technical scheme: A flow-promoting circulation temperature regulating type battery pack assembly, comprising: a base, and a support block fixedly installed at the bottom side of the base, a locking bolt being installed at the center of the support block; A temperature-regulating fixing mechanism includes a connecting column and a limiting pressure plate. The bottom of the connecting column is detachably fixed to the side of the top of the base. The limiting pressure plate is fixedly installed at the top of the connecting column. A circular hole is opened on the surface of the limiting pressure plate. A bent air pipe is fixedly installed at the bottom of the limiting pressure plate. The exhaust end of the bent air pipe is fixedly installed to the surface of the connecting column. A heat-conducting component is installed at the bottom of the bent air pipe. A V-shaped snap-fit ​​plate is fixedly installed on the side of the bottom of the connecting column near the locking bolt. An air outlet cylinder is fixedly installed in the middle of the bottom of the connecting column. An air passage is opened in the middle of the connecting column. Cooling gas is blown into the inside of the bent air pipe. Under the action of gas pressure, the cooling gas quickly enters the air passage from the bent air pipe and is installed on the top of the battery assembly in conjunction with the limiting pressure plate. Under the action of heat transfer, the flow of gas can carry away heat and cool the battery assembly, making the battery assembly less prone to high temperature. A battery assembly is installed between the base and the limiting pressure plate, and a blower mechanism is installed between the base and the air inlet end of the bent air pipe.

[0006] Preferably, the connecting columns are installed vertically, and there are four connecting columns, which are evenly distributed on the side of the top of the base.

[0007] Preferably, the battery components are evenly distributed at the bottom of the limiting pressure plate, the circular holes are evenly distributed on the surface of the limiting pressure plate, and the top of the battery components passes through the center of the circular holes.

[0008] Preferably, there are four bent air tubes, and the four bent air tubes are evenly distributed at the bottom of the limiting pressure plate, and the bent air tubes, air passages and air outlet cylinders are connected.

[0009] Preferably, the heat-conducting component includes a connecting disc, the top of which is fixedly installed to the bottom of the bent air pipe. A T-shaped rod is fixedly connected to the middle of the bottom of the connecting disc, and a heat-conducting sheet is fixedly connected to the outer surface of the T-shaped rod. The outer edge of the heat-conducting sheet, away from the T-shaped rod, is in contact with the surface of the battery assembly. With the connection of the connecting disc and the T-shaped rod, the outer edge of the heat-conducting sheet, away from the T-shaped rod, is in contact with the surface of the battery assembly, thus providing support between adjacent battery components. This makes the battery assembly less prone to tilting and shaking, resulting in a more stable overall battery assembly.

[0010] Preferably, the T-shaped rod is installed vertically, and the heat-conducting plates are evenly distributed on the outer surface of the T-shaped rod.

[0011] By attaching the outer edge of the heat-conducting sheet to the surface of the battery module, the heat of the battery module is dissipated through the heat conduction effect of the heat-conducting sheet. Furthermore, the heat-conducting sheet is evenly distributed on the outer surface of the T-shaped rod, which can increase the heat conduction efficiency and quickly dissipate the heat of the battery module.

[0012] Preferably, the base includes a supporting rectangular plate. The top edge of the supporting block is fixedly installed at the corner of the bottom of the supporting rectangular plate. The bottom end of the connecting column is fixedly installed at the top edge of the supporting rectangular plate. A limit ring is fixedly connected to the top of the supporting rectangular plate. The bottom end of the battery assembly is embedded inside the limit ring. A curved gas flow channel is opened inside the supporting rectangular plate. A circular blind hole is opened on the top edge of the supporting rectangular plate near the connecting column. The exhaust cylinder is inserted into the circular blind hole. An exhaust hopper is fixedly installed on the surface of the supporting rectangular plate near the exhaust port of the curved gas flow channel. The base is installed at the center of the supporting block by a locking bolt. The supporting block and the supporting rectangular plate can be installed at the designated position of the equipment using the locking bolt. After the connecting column is installed on the top edge of the supporting rectangular plate, the V-shaped snap-fit ​​plate is inserted into the edge of the hexagonal nut head at the top of the locking bolt. The edge of the hexagonal nut head at the top of the locking bolt is embedded in the V-shaped snap-fit ​​plate, forming a self-locking mechanism for the hexagonal nut head at the top of the locking bolt, making it less likely for the screw to come loose.

[0013] Preferably, the limiting rings are evenly distributed on the top of the supporting rectangular plate, and the circular blind hole, the curved gas flow channel and the exhaust hopper are connected. The exhaust hopper is conical. As the gas is discharged from the outlet of the curved gas flow channel, the gas discharged from the outlet of the exhaust hopper is affected by the cone shape, which can increase the gas flow speed, promote gas flow, and help accelerate the cooling of the battery assembly.

[0014] By inserting the exhaust cylinder into the interior of the circular blind hole, the cooling gas is discharged from the exhaust cylinder and then enters the interior of the curved gas flow channel. The curved gas flow channel is curved, which increases the contact area between the cooling gas and the supporting rectangular plate, and helps to remove the heat generated at the bottom of the battery assembly.

[0015] By using a supporting rectangular plate to support the bottom of the battery module and a limiting pressure plate to limit and fix the top of the battery module, the battery module is not in a sealed space, which further helps to dissipate heat.

[0016] Preferably, the blower mechanism includes a three-way connecting pipe, the outlet end of which is fixedly installed with the inlet end of the bent air pipe. A connecting round pipe is fixedly installed at the air port at the bottom of the three-way connecting pipe. A blower pump is detachably fixedly installed at the bottom of the connecting round pipe. A right-angle connecting plate is fixedly installed at the bottom of the blower pump. The blower pump blows cooling gas, which, under the delivery of the connecting round pipe, enters the interior of the three-way connecting pipe, facilitating the entry of cooling gas into the interior of the bent air pipe. By controlling the blowing speed and volume of the blower pump, and by controlling the flow speed and volume of the cooling gas, combined with the continuous flow of cooling gas in the bent air pipe into the air passage and the bent gas flow passage, the temperature can be controlled and adjusted.

[0017] Preferably, the connecting round pipe is installed vertically, the bent air pipe, the tee connecting pipe and the connecting round pipe are connected, and the bottom end of the connecting round pipe is connected to the air outlet of the blower.

[0018] This invention provides a current-promoting, temperature-regulating battery pack assembly. It offers the following advantages: 1. This flow-promoting, temperature-regulating battery pack assembly, under the action of gas pressure, allows cooling gas to quickly enter the interior of the air passage from the bent air pipe, and is installed on the top of the battery assembly with a limiting pressure plate. Under the action of heat transfer, as the gas flows, it can carry away heat and cool the battery assembly, making it less likely for the battery assembly to overheat.

[0019] Second, this flow-promoting, temperature-regulating battery pack assembly, with the connection between the connecting disc and the T-shaped rod, allows the outer edge of the heat-conducting plate, away from the T-shaped rod, to fit against the surface of the battery assembly. This provides support between adjacent battery components, making the battery assembly less prone to tilting or shaking, and resulting in a more stable overall battery assembly.

[0020] Third, this flow-promoting, temperature-regulating battery pack assembly uses a heat-conducting plate that is attached to the surface of the battery assembly at the outer edge. The heat is dissipated through the heat conduction of the heat-conducting plate. Furthermore, the heat-conducting plate is evenly distributed on the outer surface of the T-shaped rod, which increases the heat conduction efficiency and allows the heat of the battery assembly to be dissipated quickly.

[0021] Fourth, in this flow-promoting, temperature-regulating battery pack assembly, after the connecting column is installed on the side of the top of the supporting rectangular plate, the V-shaped snap-fit ​​plate is inserted into the edge of the hexagonal nut head at the top of the locking bolt, so that the edge of the hexagonal nut head at the top of the locking bolt is embedded in the interior of the V-shaped snap-fit ​​plate, forming a self-locking mechanism for the hexagonal nut head at the top of the locking bolt, making it less likely for the threads to come loose.

[0022] 5. This flow-promoting, temperature-regulating battery pack assembly inserts an exhaust cylinder into the interior of a circular blind hole, allowing the cooling gas to exit from the exhaust cylinder and then enter the interior of a curved gas flow channel. The curved gas flow channel increases the contact area between the cooling gas and the supporting rectangular plate, which helps to remove the heat generated at the bottom of the battery assembly.

[0023] VI. In this flow-promoting circulating temperature-regulating battery pack assembly, as gas is discharged from the outlet of the curved gas flow channel, the gas discharged from the outlet of the exhaust hopper is conical. The conical shape of the exhaust hopper increases the gas flow velocity, promotes gas flow, and helps to accelerate the cooling of the battery pack assembly.

[0024] 7. This flow-promoting, temperature-regulating battery pack assembly utilizes a supporting rectangular plate to support the bottom of the battery assembly, and a limiting pressure plate to limit and fix the top of the battery assembly, so that the battery assembly is not in a sealed space, which further helps to dissipate heat.

[0025] 8. In this flow-promoting, temperature-regulating battery pack assembly, cooling gas enters the interior of the three-way connecting pipe, facilitating the entry of cooling gas into the interior of the bent air pipe. By controlling the blowing speed and volume of the cooling gas through the blower, and by combining the flow speed and volume of the cooling gas with the continuous flow of cooling gas into the air passage and the bent air passage, the temperature can be controlled for temperature regulation.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] For the first embodiment, please refer to... Figures 1-6 The present invention provides a technical solution: A current-enhancing, temperature-regulating battery pack assembly includes: The base 1 and the support block 2 fixedly installed on the bottom side of the base 1, with a locking bolt 3 installed at the center of the support block 2; The temperature-regulating fixing mechanism 4 includes a connecting column 41 and a limiting pressure plate 42. The bottom of the connecting column 41 is detachably fixed to the side of the top of the base 1. The limiting pressure plate 42 is fixedly installed on the top of the connecting column 41. A circular hole 43 is opened on the surface of the limiting pressure plate 42. A bent air pipe 44 is fixedly installed on the bottom of the limiting pressure plate 42. The exhaust end of the bent air pipe 44 is fixedly installed to the surface of the connecting column 41. A heat-conducting component 45 is installed on the bottom side of the connecting column 41, near the locking bolt 3. A V-shaped snap-fit ​​plate 46 is fixedly installed, and an air outlet cylinder 47 is fixedly installed at the middle of the bottom of the connecting square column 41. An air passage 48 is opened at the middle of the connecting square column 41. Cooling gas is blown into the inside of the bent air pipe 44, and under the action of gas pressure, the cooling gas quickly enters the air passage 48 from the bent air pipe 44. Combined with the limiting pressure plate 42, it is installed on the top of the battery assembly 5. Under the action of heat transfer, the heat can be carried away with the flow of gas, which has a cooling effect on the battery assembly 5, making the battery assembly 5 less prone to high temperature. The connecting square columns 41 are installed vertically. There are four connecting square columns 41, and the four connecting square columns 41 are evenly distributed on the top side of the base 1.

[0030] A battery assembly 5 is installed between the base 1 and the limiting pressure plate 42, and a blower assembly 6 is installed between the base 1 and the air inlet end of the bent air pipe 44.

[0031] The battery assembly 5 is evenly distributed on the bottom of the limiting pressure plate 42, and the round holes 43 are evenly distributed on the surface of the limiting pressure plate 42. The top of the battery assembly 5 passes through the center of the round hole 43.

[0032] There are four bent air tubes 44, and the four bent air tubes 44 are evenly distributed at the bottom of the limiting pressure plate 42. The bent air tubes 44, the air passage 48 and the air outlet cylinder 47 are connected.

[0033] The heat-conducting component 45 includes a connecting disc 451. The top of the connecting disc 451 is fixedly installed to the bottom of the bent air pipe 44. A T-shaped rod 452 is fixedly connected to the middle of the bottom of the connecting disc 451. A heat-conducting plate 453 is fixedly connected to the outer circular surface of the T-shaped rod 452. The outer edge of the heat-conducting plate 453, away from the T-shaped rod 452, is in contact with the surface of the battery assembly 5. With the connection of the connecting disc 451 and the T-shaped rod 452, the outer edge of the heat-conducting plate 453, away from the T-shaped rod 452, is in contact with the surface of the battery assembly 5, which can support the adjacent battery assemblies 5, making the battery assembly 5 less prone to tilting and shaking, and making the battery assembly 5 more stable.

[0034] The T-shaped rod 452 is installed vertically, and the heat-conducting plates 453 are evenly distributed on the outer surface of the T-shaped rod 452. The outer edge of the heat-conducting plates 453 is attached to the surface of the battery assembly 5. Through the heat conduction effect of the heat-conducting plates 453, the heat of the battery assembly 5 is dissipated. In addition, the heat conduction efficiency is increased by the even distribution of the heat-conducting plates 453 on the outer surface of the T-shaped rod 452, which can quickly dissipate the heat of the battery assembly 5.

[0035] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 8 As shown: The base 1 includes a supporting rectangular plate 101. A supporting block 2 is fixedly installed at the top edge and the bottom corner of the supporting rectangular plate 101. The bottom end of a connecting square column 41 is fixedly installed at the top edge of the supporting rectangular plate 101. A limiting ring 102 is fixedly connected to the top of the supporting rectangular plate 101. The bottom end of the battery assembly 5 is embedded inside the limiting ring 102. A curved gas flow channel 103 is provided inside the supporting rectangular plate 101. A circular blind hole 104 is provided on the top edge of the supporting rectangular plate 101 near the connecting square column 41. An exhaust cylinder 47 is inserted into the circular blind hole 104. An exhaust hopper 105 is fixedly installed on the surface of the support block 2 near the outlet of the curved gas flow channel 103. It is installed at the center of the support block 2 by locking bolts 3. The support block 2 and the support rectangular plate 101 can be installed at the designated position of the equipment by locking bolts 3. After the connecting column 41 is installed on the side of the top of the support rectangular plate 101, the V-shaped snap plate 46 is inserted into the edge of the hexagonal nut head at the top of the locking bolt 3. The edge of the hexagonal nut head at the top of the locking bolt 3 is embedded in the interior of the V-shaped snap plate 46, forming a self-locking effect on the hexagonal nut head at the top of the locking bolt 3, which makes it less likely for the threads to come loose.

[0036] The limiting rings 102 are evenly distributed on the top of the supporting rectangular plate 101. The circular blind hole 104, the curved gas flow channel 103 and the exhaust hopper 105 are connected. The exhaust hopper 105 is conical and is inserted into the interior of the circular blind hole 104 through the exhaust cylinder 47. After the cooling gas is discharged from the exhaust cylinder 47, the cooling gas enters the interior of the curved gas flow channel 103. The curved gas flow channel 103 is curved, which increases the contact area between the cooling gas and the supporting rectangular plate 101, and helps to remove the heat emitted from the bottom of the battery assembly 5.

[0037] As gas is discharged from the outlet of the curved gas flow channel 103, the gas discharged from the outlet of the exhaust hopper 105 is conical. The conical shape of the exhaust hopper 105 increases the gas flow velocity, promotes gas flow, and helps to accelerate the cooling of the battery assembly 5.

[0038] The bottom of the battery assembly 5 is supported by the supporting rectangular plate 101, and the top of the battery assembly 5 is limited and fixed by the limiting pressure plate 42, so that the battery assembly 5 is not in a closed space, which further helps to dissipate heat.

[0039] The third embodiment is based on the first and second embodiments; please refer to [link / reference]. Figures 1 to 9 As shown: The blower mechanism 6 includes a three-way connecting pipe 61, the air outlet of the three-way connecting pipe 61 is fixedly installed with the air inlet of the bent air pipe 44, a connecting round pipe 62 is fixedly installed at the air port at the bottom of the three-way connecting pipe 61, a blower pump 63 is detachably fixedly installed at the bottom of the connecting round pipe 62, and a right-angle connecting plate 64 is fixedly installed at the bottom of the blower pump 63.

[0040] The air pump 63 is fixedly installed between the right-angle connecting plate 64 and the supporting rectangular plate 101, making the overall structure of the air pump 63 more stable. When the operator starts the air pump 63, the air pump 63 blows the cooling gas. The cooling gas is transported by the connecting round pipe 62 and enters the interior of the three-way connecting pipe 61, which facilitates the entry of the cooling gas into the interior of the bent air pipe 44. By controlling the blowing speed and blowing volume of the air pump 63, and by controlling the flow speed and flow volume of the cooling gas, combined with the continuous flow of the cooling gas in the bent air pipe 44 into the air passage 48 and the bent gas flow passage 103, the temperature can be controlled and adjusted.

[0041] The connecting round pipe 62 is installed vertically, and the bend air pipe 44, the three-way connecting pipe 61 and the connecting round pipe 62 are connected. The bottom end of the connecting round pipe 62 is connected to the air outlet of the blower pump 63.

[0042] In use, first install the support block 2 at the center by tightening the bolt 3, and then use the bolt 3 to install the support block 2 and the support rectangular plate 101 at the designated position of the equipment. At this point, the battery assembly 5 is installed on the top of the supporting rectangular plate 101, so that the battery assembly 5 is embedded inside the limiting ring 102, and the battery assembly 5 can be initially limited. After the connecting square column 41 is installed on the side of the top of the supporting rectangular plate 101, the V-shaped snap plate 46 is inserted into the edge of the hexagonal nut head at the top of the locking bolt 3, so that the edge of the hexagonal nut head at the top of the locking bolt 3 is embedded in the interior of the V-shaped snap plate 46, forming a self-locking mechanism for the hexagonal nut head at the top of the locking bolt 3, making it less likely for the threads to come loose. Next, the limiting pressure plate 42 is installed on the top of the connecting square column 41, so that the top of the battery assembly 5 passes through the center of the round hole 43, and the battery assembly 5 can be fixed. Meanwhile, with the connection between the connecting disc 451 and the T-shaped rod 452, the outer edge of the heat-conducting plate 453 and the side away from the T-shaped rod 452 are in contact with the surface of the battery assembly 5, which can support the adjacent battery assemblies 5, so that the battery assembly 5 is less likely to tilt or shake, and the battery assembly 5 is more stable. Furthermore, the heat is dissipated from the battery assembly 5 by attaching the outer edge of the heat-conducting sheet 453 to the surface of the battery assembly 5 through the heat conduction effect of the heat-conducting sheet 453. In addition, the heat-conducting sheet 453 is evenly distributed on the outer circular surface of the T-shaped rod 452, which can increase the heat conduction efficiency and quickly dissipate the heat of the battery assembly 5. The operator starts the blower pump 63 to blow the cooling gas. The cooling gas is delivered by the connecting pipe 62 and enters the interior of the three-way connecting pipe 61, which facilitates the entry of the cooling gas into the bent air pipe 44. By controlling the blowing speed and volume of the cooling gas by the blower pump 63, and by controlling the flow speed and volume of the cooling gas, combined with the continuous flow of the cooling gas in the bent air pipe 44 into the air passage 48 and the curved gas flow passage 103, the temperature can be controlled and adjusted. Furthermore, cooling gas is blown into the inside of the bent air pipe 44, and under the action of gas pressure, the cooling gas quickly enters the air passage 48 from the bent air pipe 44 and is installed on the top of the battery assembly 5 in conjunction with the limiting pressure plate 42. Under the action of heat transfer, the heat can be carried away with the flow of gas, which has a cooling effect on the battery assembly 5, making the battery assembly 5 less prone to high temperature. Furthermore, by inserting the exhaust cylinder 47 into the interior of the circular blind hole 104, the cooling gas is discharged from the exhaust cylinder 47 and then enters the interior of the curved gas flow channel 103. The curved gas flow channel 103 is curved, which increases the contact area between the cooling gas and the supporting rectangular plate 101, and helps to remove the heat emitted from the bottom of the battery assembly 5. As the gas is discharged from the outlet of the curved gas flow channel 103, the gas discharged from the outlet of the exhaust hopper 105 is conical. The conical shape of the exhaust hopper 105 increases the gas flow velocity, promotes gas flow, and helps to accelerate the cooling of the battery assembly 5. The bottom of the battery assembly 5 is supported by the supporting rectangular plate 101, and the top of the battery assembly 5 is limited and fixed by the limiting pressure plate 42, so that the battery assembly 5 is not in a closed space, which further helps to dissipate heat.
