Description

Technical Field

[0001] This utility model belongs to the field of battery system heat dissipation technology, and in particular relates to a high-efficiency heat dissipation device for battery systems. Background Technology

[0002] Battery system heat dissipation is crucial for ensuring battery performance and safety. It dissipates the heat generated during battery operation in a timely manner through various methods, such as liquid cooling and air cooling, to prevent overheating that could lead to performance degradation, shortened lifespan, or even thermal runaway. This ensures that the battery operates within a suitable temperature range, improves system stability and reliability, and facilitates the efficient application of batteries in numerous fields.

[0003] When using air cooling to dissipate heat from batteries, filter plates are usually installed at the air inlet to filter the incoming air and prevent dust and impurities from entering the equipment. However, some existing battery systems' high-efficiency heat dissipation devices do not allow for easy removal of the filter plates, which may prevent thorough cleaning. As a result, dust trapped on the filter plates may accumulate over time, clogging the filter pores and affecting ventilation, thus reducing heat dissipation efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency heat dissipation device for a battery system. By providing a disassembly mechanism, it solves the problem that the filter plate is not easy to disassemble in some existing high-efficiency heat dissipation devices for battery systems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a high-efficiency heat dissipation device for a battery system, comprising a housing, on which a disassembly mechanism and a water-cooling mechanism are provided.

[0007] The disassembly mechanism includes an air-cooled box fixedly connected to the left side of the housing. A filter plate is slidably connected to the inner wall of the air-cooled box. Several positioning seats are fixedly connected to the inner wall of the air-cooled box. Several connecting rods are fixedly connected to the right side of the filter plate. The right ends of the connecting rods extend into the interior of the corresponding positioning seats and are slidably connected to the corresponding positioning seats. Two sliding grooves are opened on the front and rear sides of the air-cooled box. Positioning pins are slidably connected to the inner walls of the sliding grooves. The ends of the positioning pins near the corresponding connecting rods extend into the interior of the corresponding positioning seats and pass through the corresponding connecting rods. The positioning pins are slidably connected to the corresponding positioning seats and connecting rods. Limit plates are fixedly connected to the positioning pins. Springs are wound around the positioning seats. A pull plate is fixedly connected between the ends of two corresponding positioning pins away from the corresponding connecting rods.

[0008] Furthermore, two support frames are fixedly connected to the inner wall of the air-cooled box, and two fans are fixedly connected to the two support frames.

[0009] Furthermore, ventilation holes are provided on both the front and rear sides of the housing, and a cover plate is provided on the top of the housing.

[0010] Furthermore, the water-cooling mechanism includes a partition fixedly connected inside the housing, and a plurality of batteries are disposed on the top of the partition.

[0011] Furthermore, a coolant tank is fixedly connected to the inner bottom wall of the housing, and a water pump is fixedly connected to the top of the partition.

[0012] Furthermore, a water pumping pipe is fixedly connected between the water pump and the coolant tank, and a water delivery pipe is fixedly connected to the front side of the water pump.

[0013] Furthermore, the end of the water supply pipe away from the water pump extends to the bottom of the partition and is fixedly connected to the partition. A U-shaped coil is fixedly connected to the end of the water supply pipe away from the water pump. A return pipe is fixedly connected to the end of the U-shaped coil away from the water supply pipe. The end of the return pipe away from the U-shaped coil is fixedly connected to the coolant tank.

[0014] Furthermore, a water injection pipe is fixedly connected to the top of the coolant tank, the top end of the water injection pipe passes through the cover plate and is slidably connected to the cover plate, and a drain pipe is fixedly connected to the right side of the coolant tank, the right end of the drain pipe extends to the outside of the shell and is fixedly connected to the shell.

[0015] This utility model has the following beneficial effects:

[0016] 1. By setting up a disassembly mechanism, pulling the pull plate moves the positioning pin, which in turn moves the limiting plate. The limiting plate then causes the spring to contract, and the positioning pin moves away from the connecting rod, allowing the connecting rod to smoothly disengage from the positioning seat. The filter plate then moves away from the air-cooled box, causing the filter plate to move along with the connecting rod. This disassembly mechanism facilitates the removal of the filter plate, allowing for thorough cleaning. This prevents dust from accumulating on the filter plate over time, which can clog it and affect airflow. Disassembling and cleaning the filter plate removes accumulated dust, ensuring its breathability and maintaining a stable airflow. This ensures the fan can effectively draw cool air into the housing, providing good heat dissipation for the battery.

[0017] 2. By setting up a water-cooling mechanism and starting the water pump, the water pump draws coolant from the coolant tank through the suction pipe and then transfers the coolant into the U-shaped coil through the delivery pipe. Heat exchange occurs through the contact between the U-shaped coil and the separator. Finally, the coolant in the U-shaped coil returns to the coolant tank through the return pipe. The water-cooling mechanism enhances heat dissipation, effectively and comprehensively reducing battery temperature. At the same time, it optimizes the heat transfer path, resulting in better temperature uniformity of the battery, avoiding localized overheating, ensuring uniform internal battery reactions, which is beneficial to improving battery performance and lifespan. It also reduces the temperature difference between individual batteries within the casing, improving system stability and safety, precisely controlling temperature, effectively avoiding battery safety hazards, and to a certain extent reducing the risk of battery overheating due to the failure of a single heat dissipation method.

[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

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

[0029] Please see Figure 1-6As shown, this utility model is a high-efficiency heat dissipation device for a battery system, including a housing 1. The housing 1 is equipped with a disassembly mechanism 2 and a water-cooling mechanism 3. The disassembly mechanism 2 includes an air-cooled box 21 fixedly connected to the left side of the housing 1. A filter plate 22 is slidably connected to the inner wall of the air-cooled box 21. Several positioning seats 23 are fixedly connected to the inner wall of the air-cooled box 21. Several connecting rods 24 are fixedly connected to the right side of the filter plate 22. The right ends of the connecting rods 24 extend into the interior of the corresponding positioning seats 23 and are slidably connected to them. Two sliding grooves 25 are provided on the front and rear sides of the air-cooled box 21. Positioning pins 26 are slidably connected to the inner walls of the sliding grooves 25. One end of each positioning pin 26 near the corresponding connecting rod 24 extends into the interior of the corresponding positioning seat 23 and passes through the corresponding connecting rod 24. The positioning pins 26 are slidably connected to the corresponding positioning seats 23 and connecting rods 24. Limit plates 27 are fixedly connected to each positioning pin 26. Springs 28 are wound around the positioning seats 23. Pull plates 29 are fixedly connected between the ends of the two corresponding positioning pins 26 away from the corresponding connecting rods 24. Two support frames 210 are fixedly connected to the inner wall of the air-cooled box 21. Two fans 211 are fixedly connected to the two support frames 210. Exhaust holes 212 are opened on the front and rear sides of the housing 1. A cover plate 213 is provided on the top of the housing 1. The filter plate 22 is easily disassembled by the disassembly mechanism 2, so that the filter plate 22 can be thoroughly cleaned. This prevents the filter plate 22 from accumulating dust over a long period of use, which would cause the filter plate 22 to become clogged and affect the air intake. By disassembling and cleaning the filter plate 22, the dust accumulated on the surface of the filter plate 22 can be removed, ensuring the air permeability of the filter plate 22 and maintaining a stable air intake. This ensures that the fans 211 can effectively introduce cold air into the housing 1, providing good heat dissipation conditions for the battery 32.

[0030] The water-cooling mechanism 3 includes a partition 31 fixedly connected inside the housing 1. Several batteries 32 are mounted on the top of the partition 31. A coolant tank 33 is fixedly connected to the inner bottom wall of the housing 1. A water pump 34 is fixedly connected to the top of the partition 31. A water pump pipe 35 is fixedly connected between the water pump 34 and the coolant tank 33. A water supply pipe 36 is fixedly connected to the front of the water pump 34. The end of the water supply pipe 36 away from the water pump 34 extends to the bottom of the partition 31 and is fixedly connected to the partition 31. A U-shaped coil 37 is fixedly connected to the end of the water supply pipe 36 away from the water pump 34. A return pipe 38 is fixedly connected to the end of the U-shaped coil 37 away from the water supply pipe 36. The end of the return pipe 38 away from the U-shaped coil 37 is fixedly connected to the coolant tank 33. A water injection pipe 39 is fixedly connected to the top of the coolant tank 33. The top end of the water inlet pipe 39 passes through the cover plate 213 and is slidably connected to the cover plate 213. The right side of the coolant tank 33 is fixedly connected to the drain pipe 310. The right end of the drain pipe 310 extends to the outside of the housing 1 and is fixedly connected to the housing 1. The water cooling mechanism 3 enhances the heat dissipation effect, which can efficiently and comprehensively reduce the temperature of the battery 32. At the same time, it optimizes the heat transfer path, which can make the temperature uniformity of the battery 32 better, avoid local overheating, ensure uniform internal reaction of the battery 32, improve the performance and life of the battery 32, reduce the temperature difference of each battery 32 in the housing 1, improve the stability and safety of the system, accurately control the temperature, effectively avoid the safety hazards of the battery 32, and reduce the risk of battery 32 overheating due to the failure of a single heat dissipation method to a certain extent.

[0031] One specific application of this embodiment is as follows: When the fan 211 is working, it blows external air, which is cooler than the internal temperature of the housing 1, into the housing 1. When the external air is blown into the housing 1, the hot air inside the housing 1 is forced to move and is discharged from the housing 1 through the exhaust port 212, causing the air inside the housing 1 to circulate and carry away the hot air inside the housing 1, thereby cooling the battery 32 inside the housing 1. At the same time, when the fan 211 is working, the air blown into the housing 1 is filtered by the filter plate 22, thereby filtering out dust, particulate impurities, etc., and preventing air from entering the air-cooled box 21 and entering the interior of the housing 1 through the air-cooled box 21, which could damage the battery and fan 211 inside the housing 1. Pulling the pull plate 29 will move the positioning pin 26. When the filter plate 22 moves, the limiting plate 27 moves, and the spring 28 contracts as the limiting plate 27 moves. When the positioning pin 26 moves, it will release the restriction on the connecting rod 24, allowing the connecting rod 24 to smoothly disengage from the positioning seat 23. Then, the filter plate 22 can be moved away from the air-cooled box 21 to disassemble it, which facilitates thorough cleaning of the positioning seat 23. This prevents excessive accumulation of trapped dust on the surface of the filter plate 22 during long-term use, which can cause filter screen blockage, affect the ventilation efficiency of the filter plate 22, and thus affect the heat dissipation effect. When the filter plate 22 is installed, the connecting rod 24 on the filter plate 22 is slid into the corresponding positioning seat 23 while the pull plate 29 is pulled. There are four connecting rods 24 and four positioning seats 23. After the connecting rod 24 has fully slid into the positioning seat 23, the pull plate 29 is released to quickly complete the installation of the filter plate 22.

[0032] When the temperature of the battery 32 inside the casing 1 is too high, the water pump 34 is started. The water pump 34 draws out the coolant from the coolant tank 33 through the water pump pipe 35, and then transmits the coolant into the U-shaped coil 37 through the water supply pipe 36. Heat exchange occurs between the U-shaped coil 37 and the separator 31, carrying away the heat from the separator 31, thereby reducing the temperature of the battery 32 and achieving the effect of heat dissipation and cooling. This further enhances the heat dissipation efficiency. The coolant in the U-shaped coil 37 returns to the coolant tank 33 through the return pipe 38, thus circulating the coolant. This allows the coolant to be recycled and makes it easier for the flowing coolant to carry away the heat from the separator 31. Coolant is added to the coolant tank 33 through the water injection pipe 39, and the coolant in the coolant tank 33 is discharged through the drain pipe 310.
