Description

Technical Field

[0001] This utility model application relates to the field of battery module technology, specifically a water-cooled battery module for mining. Background Technology

[0002] A battery module is an intermediate energy storage unit that integrates multiple individual batteries through series and parallel connections, and is equipped with a battery management system, thermal management components, mechanical structure, and electrical interfaces. Its core function is to boost the energy and voltage of individual batteries to a suitable level, while realizing charge and discharge control, status monitoring, and safety protection through the BMS. The module structure typically includes a frame, heat dissipation system, insulation materials, and connectors, taking into account both mechanical strength and thermal stability. As a sub-module of the battery system, the module design needs to balance energy density, lifespan, and cost. It is widely used in electric vehicles, energy storage devices, and other fields, and is a key level connecting individual batteries and the complete battery system.

[0003] Currently, battery modules typically use water cooling for heat dissipation. The traditional method is to place the battery module on a water cooling plate. However, when the battery module is working, the water cooling plate can often only cool the bottom of the battery module. Some heat is still dissipated from the top of the battery module, and there is often no heat dissipation device on the top of the battery module. It can only rely on natural air cooling, which has low heat dissipation efficiency. Summary of the Invention

[0004] To address the issue that water-cooled plates often only cool the bottom of the battery module, while the top of the battery module lacks a heat dissipation device and relies solely on natural air cooling, resulting in low heat dissipation efficiency, this invention provides a water-cooled battery module for mining to solve the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A water-cooled battery module for mining includes a water-cooled plate body, a battery module body mounted on the water-cooled plate body, water-cooled pipes inside the water-cooled plate body, a battery connection slot on one side of the battery module body, a top plate above the battery module body, two cylinders symmetrically fixed on the top surface of the water-cooled plate body, two outer sleeve rods fixed at the two ends of the top surface of the water-cooled plate body away from the cylinders, an inner sleeve rod slidably mounted inside each outer sleeve rod, the top surface of each inner sleeve rod being fixedly connected to the bottom surface of the top plate, a plurality of cooling fans fixed inside the top plate, an air inlet on the top surface of the top plate, and an air outlet on the bottom surface of the top plate.

[0007] Furthermore, storage rods are fixed inside the four sides of the top plate, and a dustproof net is wound around each storage rod. A coil spring is provided between the dustproof net and the storage rod. The inner end of the dustproof net is fixedly connected to the coil spring, and the coil spring is fixedly connected to the storage rod. A fixing hook is fixed to the outer end of the dustproof net. Several limiting devices are fixed on the four sides of the water-cooled plate body, and the fixing hook is fixedly connected to the water-cooled plate body through the limiting devices.

[0008] Furthermore, two connecting nuts are rotatably provided on the bottom surface of the top plate near the cylinder, and each connecting nut is threadedly connected to the output end of the cylinder.

[0009] Furthermore, the dustproof net has a slot at one end near the battery connection slot that matches the shape of the battery connection slot, and the length of the dustproof net is greater than the maximum stroke of the cylinder.

[0010] Furthermore, the limiting device includes a first limiting buckle, and a second limiting buckle is slidably connected to the end of the first limiting buckle away from the main body of the water-cooled plate.

[0011] Furthermore, the radius of the first limiting buckle is the same as the radius of the second limiting buckle, and the radius of the first limiting buckle is the same as the radius of the inner buckle of the fixed hook.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, the battery module body is raised and lowered by a cylinder, and a cooling fan is installed inside the battery module body. The cooling fan drives the airflow speed on the top surface of the battery module body, which improves the heat dissipation efficiency of the top of the battery module body. This solves the problem that water cooling plates can only cool the bottom of the battery module, while the top of the battery module often lacks a heat dissipation device and can only rely on natural air heat dissipation, resulting in low heat dissipation efficiency.

[0014] 2. In this utility model, dustproof nets are set around the battery module body and connected to the storage rod by coil springs, so that the dustproof nets can be stored on the side of the top plate. When the battery module body is working, the dustproof nets are pulled out from the inside of the top plate by pulling the fixing hooks, and then fixed by the first limit buckle and the second limit buckle, so that the battery module body will not be affected by the dust in the mining area when working, thus solving the problem that the working efficiency of the battery module body is easily affected in the working scene with a lot of dust in the mining area.

[0021] To make the purpose, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4A water-cooled battery module for mining includes a water-cooled plate body 1, a battery module body 2 mounted on the water-cooled plate body 1, a water-cooled pipe 4 inside the water-cooled plate body 1, a battery connection groove 3 on one side of the battery module body 2, a top plate 5 above the battery module body 2, two cylinders 6 symmetrically fixed on the top surface of the water-cooled plate body 1, two outer sleeve rods 8 fixed at the two ends of the top surface of the water-cooled plate body 1 away from the cylinders 6, an inner sleeve rod 9 slidably mounted inside each outer sleeve rod 8, and the top surface of each inner sleeve rod 9 fixedly connected to the bottom surface of the top plate 5, a plurality of cooling fans 11 fixed inside the top plate 5, an air inlet 10 on the top surface of the top plate 5, and an air outlet 12 on the bottom surface of the top plate 5, so that the cooling fans 11 dissipate heat from the top of the battery module body 2.

[0023] Specifically, two connecting nuts 7 are rotatably installed on the bottom surface of the top plate 5 near the cylinder 6. Each connecting nut 7 is threadedly connected to the output end of the cylinder 6, thereby improving the stability between the cylinder 6 and the water-cooled plate body 1.

[0024] As an optimization solution, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, storage rods 13 are fixed inside the four sides of the top plate 5. Each storage rod 13 is wrapped with a dustproof net 14. A coil spring is provided between the dustproof net 14 and the storage rod 13. The inner end of the dustproof net 14 is fixedly connected to the coil spring, and the coil spring is fixedly connected to the storage rod 13. A fixing hook 15 is fixed to the outer end of the dustproof net 14. Several limiting devices are fixed on the four sides of the water-cooled plate body 1. The fixing hook 15 is fixedly connected to the water-cooled plate body 1 through the limiting devices, so that the dustproof net 14 prevents dust from entering the interior of the water-cooled plate body 1.

[0025] Specifically, the dustproof net 14 has a slot at one end near the battery connection slot 3 that matches the shape of the battery connection slot 3. The length of the dustproof net 14 is greater than the maximum stroke of the cylinder 6. The limiting device includes a first limiting buckle 16. A second limiting buckle 17 is slidably connected to the end of the first limiting buckle 16 away from the water-cooled plate body 1. The radius of the first limiting buckle 16 is the same as the radius of the second limiting buckle 17. The radius of the first limiting buckle 16 is the same as the radius of the inner buckle ring of the fixed hook 15, thereby improving the limiting effect of the first limiting buckle 16 on the fixed hook 15.

[0026] Working principle: By placing the battery module body 2 inside the water-cooled plate body 1, and then injecting water into the water-cooled plate body 1 through the water-cooling pipe 4, the water-cooled plate body 1 dissipates heat from the bottom of the battery module body 2. The inner sleeve rod 9 is then aligned with the outer sleeve rod 8 and inserted, so that the top plate 5 covers the top of the battery module body 2. At this point, by rotating the connecting nut 7, the connecting nut 7 is threadedly connected to the cylinder 6, allowing the cylinder 6 to adjust the distance between the top plate 5 and the top surface of the battery module body 2 according to its height. Simultaneously, the cooling fan 11 is activated, blowing airflow through the air inlet 10 towards the top surface of the battery module body 2, thus accelerating the cooling fan's operation. The heat dissipation efficiency of the top surface of the battery module body 2 is improved. At the same time, the fixed hooks 15 around the top plate 5 are pulled, causing the fixed hooks 15 to move the dustproof net 14 downward. Then, by putting the fixed hooks 15 on the first limit buckle 16 and sliding the second limit buckle 17, the first limit buckle 16 and the second limit buckle 17 are misaligned, so that the fixed hooks 15 are locked and fixed by the second limit buckle 17 and the first limit buckle 16. At this time, the dustproof net 14 prevents dust from entering the battery module body 2. When the staff touches the second limit buckle 17 to limit the fixed hooks 15, the coil spring on the storage rod 13 drives the dustproof net 14 to roll up, so that the dustproof net 14 is stored inside the top plate 5.
