Description

Technical Field

[0001] This utility model relates to the field of battery technology, and more specifically to a drainage structure for an energy storage cabinet. Background Technology

[0002] The electrical components (temperature control module, power module, battery pack) inside a large-capacity energy storage cabinet are mostly arranged in the same housing space. Energy storage cabinets are exposed to multiple water sources during operation, including condensate, rainwater, fire sprinkler water, and liquids sprayed during thermal runaway. Current technology uses a single drainage structure for all energy storage cabinets, which is flawed and can lead to blockages that render the entire drainage system inoperable. Utility Model Content

[0003] To address the shortcomings and defects of existing technologies, a drainage structure for energy storage cabinets with a more reasonable drainage design and improved operational reliability is provided.

[0004] A drainage structure for an energy storage cabinet, comprising: A cabinet formed by panels surrounding a frame, wherein multiple partitions are spaced at intervals from top to bottom along the height direction inside the cabinet, and are separated by the partitions to form a sequentially spaced arrangement from top to bottom: The first section is used to house the temperature control module; The second section is used to house the power modules; The third section is used to house the battery pack; The bottom partition of the first section has a through groove running vertically through it. The side wall of the cabinet is provided with a first drainage groove that is recessed inward to the bottom of the first through groove, and the first drainage groove is connected to the first through groove. The bottom partition of the second section is provided with a second through groove running vertically through it, and the side wall of the cabinet is provided with a second drainage groove that is recessed inward to the bottom of the second through groove. The second drainage groove is connected to the second through groove.

[0005] With the above structure, the energy storage cabinet drainage structure of this utility model has the following advantages compared with the prior art: During use, the water (mainly condensate) in the first zone can flow from the first channel into the first drainage channel, and finally flow to the outside. Water within the second zone (mainly infiltrated water) can flow from the second channel into the second drainage channel, eventually flowing to the outside. The entire process relies solely on gravity for drainage, which prevents internal electronic components from getting wet and extends the lifespan of the device.

[0006] Among them, due to the high waterproof performance of the temperature control module itself, it is placed in the first section at the top. The power module has relatively weak waterproof performance, so it is placed in the second section in the middle with better waterproof performance, which makes the drainage design more reasonable.

[0007] In addition, the isolation between the temperature control module, power module, and battery pack reduces mutual interference, making the device more stable and reliable in operation.

[0008] As an improvement of this utility model, first through slots are respectively provided on the left and right sides of the bottom partition of the first section. Furthermore, the left and right side walls of the cabinet are each equipped with a first drainage channel that is independently connected to the first through channel.

[0009] As an improvement of this utility model, the bottom partition of the second section is cut off at the rear, and the rear of the first section is closed by a baffle. The panel at the rear of the cabinet surrounds the rear of the first and second sections to form an exhaust channel extending vertically. The rear side of the second section is connected to the front wall of the bottom end of the exhaust duct; The second drainage trough is installed on the bottom wall of the exhaust duct.

[0010] As an improvement of this utility model, the bottom wall of the exhaust channel surrounds the second drainage groove and forms a sunken area by being recessed downward.

[0011] As an improvement of this utility model, the first channel and the second channel are respectively equipped with filter screens.

[0012] As an improvement of this utility model, an air outlet louver is also provided on the rear side of the second partition, and an air guide channel is formed between the air outlet louvers. The air guide channel is an inclined air guide structure with a front height greater than the rear height. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] Please see Figure 1-5 As shown, A drainage structure for an energy storage cabinet, comprising: The cabinet 1 is formed by the panels surrounding the frame. Multiple partitions are spaced at intervals from top to bottom along the height of the cabinet 1, creating a top-to-bottom separated structure. The first partition, 1.1, is used to accommodate the temperature control module 5; The second partition, 1.2, is used to accommodate the power module 6; The third section, 1.3, is used to house the battery pack; The bottom partition of the first section 1.1 is provided with a first through groove 1.11 running vertically through it. The side wall of the cabinet 1 is provided with a first drainage groove 1.4 that is recessed inward to the lower part of the first through groove 1.11, and the first drainage groove 1.4 is connected to the first through groove 1.11; The bottom partition of the second section 1.2 is provided with a second through groove 1.21 that runs vertically through the bottom. The side wall of the cabinet 1 is provided with a second drainage groove 1.5 that is recessed inward to the bottom of the second through groove 1.21. The second drainage groove 1.5 is connected to the second through groove 1.21.

[0021] During use, the water (mainly condensate) in the first section 1.1 can flow from the first channel 1.11 into the first drainage channel 1.4, and eventually flow to the outside. The water in the second zone 1.2 (mainly infiltrated water) can flow from the second channel 1.21 into the second drainage channel 1.5, and eventually flow to the outside. The entire process relies solely on gravity for drainage, which prevents internal electronic components from getting wet and extends the lifespan of the device.

[0022] Among them, due to the high waterproof performance of the temperature control module 5, it is placed in the first partition 1.1 at the top. The power module 6 has relatively weak waterproof performance, so it is placed in the middle of the second partition 1.2, which has better waterproof performance, making the drainage design more reasonable.

[0023] In addition, the isolation between the temperature control module 5, the power module 6, and the battery pack reduces mutual interference factors, making the device more stable and reliable in operation.

[0024] Please see Figure 2 , Figure 4 , Figure 5 As shown, first through slots 1.11 are respectively opened on the left and right sides of the bottom partition of the first section 1.1. Furthermore, the left and right side walls of the cabinet 1 are respectively provided with two sets of drainage structures, namely the first drainage channel 1.4 and the first partition 1.1, which are independently connected to the first through channel 1.11. This can improve the drainage effect and separate the drainage areas to avoid local water accumulation.

[0025] The bottom partition of the second section 1.2 is cut off at the rear, and the rear of the first section 1.1 is closed by a baffle 1.12. The panel portion of the rear side of the cabinet 1 surrounds the rear of the first section 1.1 and the second section 1.2 to form an exhaust channel 2 extending vertically. The rear side of the second partition 1.2 is connected to the bottom front wall of the exhaust duct 2, which is mainly for the exhaust of hot air from the power module 6. In some embodiments, an exhaust fan 2.2 may be installed in the exhaust duct 2. In some embodiments, the exhaust outlet of the exhaust duct 2 is arranged on the upper side of the cabinet 1. The second drainage trough 1.5 is set on the bottom wall of the exhaust channel 2. Water seeping into the exhaust channel 2 can be discharged through the drainage structure at the bottom of the exhaust channel 2, avoiding water accumulation inside, which would make the device vulnerable to damage and reduce the heat exhaust performance, thus making the device operate more stably.

[0026] The bottom wall of the exhaust duct 2 surrounds the second drainage channel 1.5, and a sunken area 2.1 is formed by the downward indentation.

[0027] If water enters the exhaust channel 2, the water can converge in the sinking area 2.1, which will facilitate drainage from the second drainage channel 1.5.

[0028] The first channel 1.11 and the second channel 1.21 are respectively equipped with filter screens 3 to prevent external debris from entering.

[0029] Please see Figure 5 As shown in the figure, the direction of airflow is indicated by red dashed lines. The second section 1.2 is also equipped with air outlet louvers 4. The air outlet louvers 4 form an air guide channel. The air guide channel is an inclined air guide structure with a front height greater than the rear height.

[0030] After the above improvements, water vapor needs to climb a certain height to pass through the air outlet louver 4 and enter the second section 1.2, making it more difficult for water vapor to enter.

[0031] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
