Technical Field

[0001] This utility model belongs to the field of battery module technology, and specifically relates to a battery module structure with heat dissipation function. Background Technology

[0002] With the construction of new power systems based on new energy sources, the penetration rate of new energy in the power system is increasing. However, the volatility, intermittency, and randomness of energy storage battery modules using new energy sources undoubtedly pose significant challenges to the safe and stable operation of the power system. Energy storage battery modules can be used in all aspects of the power system—generation, transmission, transformation, distribution, and consumption—providing various services such as peak shaving, frequency regulation, voltage regulation, and backup power, thereby improving the flexibility, economy, and security of the power system.

[0003] Patent No. 201721142942.9 discloses a battery module with a novel heat dissipation structure, including several interconnected individual battery heat dissipation units, with adjacent individual battery heat dissipation units connected by waist-shaped copper tubes; the individual battery heat dissipation unit includes an individual battery, with several heat dissipation fins evenly distributed on the front and rear sides of the individual battery, and a first square ring plate and a second square ring plate installed on the top edge and bottom edge of the individual battery, respectively. This device achieves heat dissipation through a single heat dissipation fin, resulting in a single heat dissipation mode and limited heat dissipation effect. Utility Model Content

[0004] The purpose of this invention is to provide a battery module structure with heat dissipation function to solve the problems mentioned in the background art.

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

[0006] A battery module structure with heat dissipation function includes:

[0007] The housing has a cover plate installed on one side and a battery pack inside. A heat dissipation mechanism is also provided on the housing, comprising an air-cooling component and a cooling plate component, which work together to improve heat dissipation. The air-cooling component includes an adjusting element, a heat dissipation shell, a filter, an upper air inlet, and a lower air outlet. Several sets of upper air inlets are located inside the upper part of the housing, and several sets of lower air outlets are located inside the bottom part. The upper air inlets allow air to enter, and the lower air outlets allow hot air to exit. The airflow flows from top to bottom, preventing heat from accumulating inside the housing and facilitating ventilation and heat dissipation. The heat dissipation shell is installed on the upper part of the housing via the adjusting element, positioned above the upper air inlets. Both the upper and lower ends of the heat dissipation shell are open, allowing airflow from the cooling fan to enter the housing through the upper air inlets. A cooling fan is installed inside the heat dissipation shell, and a filter is installed at the upper end of the heat dissipation shell to prevent external dust from being brought into the housing.

[0008] The cooling plate assembly includes an installation channel, a cooling plate, and a fastener. The installation channel is provided inside the outer casing, and the cooling plate is installed inside the installation channel via the fastener, which makes it easy to install or remove the cooling plate and facilitates later maintenance.

[0009] Preferably, the adjusting component includes an adjusting plate, a moving groove, and a moving block. The adjusting plate is connected to the lower end of the heat dissipation housing, and a channel is opened inside the adjusting plate for airflow. The moving blocks are connected to both sides of the lower end of the adjusting plate. The moving groove that cooperates with the moving block is opened at the upper end of the outer shell. When it is necessary to adjust the position of the heat dissipation housing and the cooling fan, the adjusting plate is pushed to move at the upper end of the outer shell, and the moving block slides inside the moving groove, thereby adjusting the position of the heat dissipation housing and the cooling fan. This allows the cooling fan to dissipate heat from the localized areas with higher temperatures inside the outer shell, preventing excessively high temperatures caused by poor air circulation inside the outer shell, which is beneficial for heat dissipation. Furthermore, temperature sensors are installed on the inner walls of the outer shell to monitor the temperature, which is beneficial for focusing ventilation and heat dissipation on the localized areas with higher temperatures.

[0010] Preferably, the adjusting component further includes limiting bolts and limiting screw holes. The limiting bolts are threaded to both sides of the adjusting plate. The upper end of the outer shell has multiple sets of limiting screw holes that cooperate with the limiting bolts. After the adjusting plate is moved to a suitable position, the adjusting plate is fixed by screwing the limiting bolts into the corresponding limiting screw holes.

[0011] Preferably, the cooling plate has a circulation channel inside, which is continuously meandering and tortuous, increasing the path of the circulation channel inside the cooling plate and increasing the contact area, which is beneficial to improving the cooling effect. One end of the circulation channel is connected to a coolant inlet pipe, and the other end of the circulation channel is connected to a coolant outlet pipe. By injecting coolant into the coolant inlet pipe and then into the circulation channel, and finally flowing out from the coolant outlet pipe, a cooling cycle is achieved, thereby improving the cooling effect of the cooling plate.

[0012] Preferably, the fixing component includes a mounting limiting plate, a mounting rod, and mounting holes. Mounting limiting plates are mounted on both the upper and lower ends of the cooling plate via rotating shafts. The mounting limiting plates are rotatably connected to the cooling plate. The mounting rod is threadedly connected to one side of the mounting limiting plate. The outer casing has mounting holes that mate with the mounting channel. The mounting holes are located on one side of the mounting channel. The mounting rod is threadedly connected to the mounting hole. When installing the cooling plate, first rotate the mounting limiting plate to the upper end of the cooling plate to avoid interference with installation. Then, insert the cooling plate into the mounting channel. Next, rotate the mounting limiting plate so that the mounting rods on it align with their corresponding mounting holes. Finally, screw the mounting rods into their respective mounting holes to secure the cooling plate. When disassembly is required, unscrew the mounting rods and rotate the mounting limiting plate to remove the cooling plate, which facilitates future maintenance.

[0013] Preferably, the inner sides of the outer casing are provided with supporting side plates, and the inner sides of the supporting side plates are provided with several sets of through holes for heat dissipation. Furthermore, strip-shaped through holes can also be provided on the outer side of the outer casing to facilitate heat dissipation.

[0014] Preferably, each end of the cover plate is equipped with a fixing bolt, and the outer shell has a screw hole on the side near the cover plate that matches the fixing bolt. The cover plate can be removed from one side of the outer shell by removing the fixing bolt, which is simple to operate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention utilizes a wind-cooling component that allows airflow to enter through the upper air inlet on the top of the outer casing and exit through the lower air outlet, carrying away heat. The airflow flows from top to bottom, preventing heat from accumulating inside the casing and circulating without dissipation, thus promoting ventilation and heat dissipation. The cooling plate is easy to install or remove, and the cooling plate assembly provides water cooling. The combined use of the wind-cooling component and the cooling plate assembly, along with multiple heat dissipation methods, further enhances the heat dissipation effect. Attached Figure Description

The air-cooling component includes an adjustment element, a heat dissipation housing 20, a filter screen 21, an upper air inlet 26, and a lower air outlet 27. Several sets of upper air inlets 26 are opened inside the upper end of the housing 10, and several sets of lower air outlets 27 are opened inside the bottom end of the housing 10. The upper air inlets 26 are used for air intake, and the lower air outlets 27 are used for... The hot air is expelled, and the airflow flows from top to bottom, which prevents the heat from accumulating inside the outer casing 10 and is conducive to ventilation and heat dissipation. A heat dissipation shell 20 is installed on the upper end of the outer casing 10 through an adjustment component. The heat dissipation shell 20 is located above the upper air inlet 26. Both the upper and lower ends of the heat dissipation shell 20 are open, which allows the airflow exhausted by the cooling fan to enter the interior of the outer casing 10 through the upper air inlet 26. A cooling fan is installed inside the heat dissipation shell 20. A filter screen 21 is provided at the upper end of the heat dissipation shell 20 to prevent external dust from being brought into the interior of the outer casing 10.

When it is necessary to adjust the position of the heat dissipation housing 20 and the cooling fan, the adjusting plate 22 is pushed to move at the upper end of the outer shell 10, and the moving block slides inside the moving groove 23, thereby adjusting the position of the heat dissipation housing 20 and the cooling fan. This allows the cooling fan to dissipate heat from the areas with higher local temperatures inside the outer shell 10, preventing excessively high temperatures caused by poor air circulation inside the outer shell 10, which is beneficial for heat dissipation. Furthermore, temperature sensors are installed on the inner walls of the outer shell 10 to monitor the temperature, which is beneficial for focusing ventilation and heat dissipation on areas with higher local temperatures.

[0032] refer to Figures 1-5 As shown, the cooling plate 30 has a circulation channel 31 inside. The circulation channel 31 is continuously meandering, which increases the path of the circulation channel 31 inside the cooling plate 30 and increases the contact area, which is beneficial to improving the cooling effect. One end of the circulation channel 31 is connected to a coolant inlet pipe 32, and the other end of the circulation channel 31 is connected to a coolant outlet pipe 33.

The mounting holes 36 are located on one side of the mounting channel. The mounting rod 35 is threadedly connected to the mounting hole 36. When installing the cooling plate 30, the mounting limit plate 34 is first... Rotate the mounting plate 34 to the upper end of the cooling plate 30 to avoid the installation limit plate 34 affecting the installation. Then insert the cooling plate 30 into the installation channel. Rotate the installation limit plate 34 to align the mounting rods 35 on the installation limit plate 34 with the corresponding mounting holes 36. Then screw the mounting rods 35 into the corresponding mounting holes 36 to fix the cooling plate 30 in place.

Several sets of through holes are opened inside the supporting side plates 37 for heat dissipation. Furthermore, strip-shaped through holes can also be opened on the outer surface of the outer shell 10 to facilitate heat dissipation.

The airflow flows from top to bottom, preventing heat from accumulating inside the outer casing 10 and circulating without dissipation, thus promoting ventilation and heat dissipation. Furthermore, the cooling plate 30 is easy to install or remove. The cooling plate assembly provides water cooling. The wind-cooling component and the cooling plate assembly work together, and multiple heat dissipation methods are used in combination, further improving the heat dissipation effect.
