[0031] Please see Figure 1 and Figure 2 This utility model provides an energy storage cabinet, including a cabinet body 1 and a fan 2. The cabinet body 1 has an air inlet 12 and an air outlet 13 on its wall panel. The fan 2 guides ambient air into the cabinet body 1 through the air inlet 12 and exhausts it through the air outlet 13. The fan 2 accelerates air circulation within the cabinet body 1, carrying away heat generated by the battery modules inside the cabinet body 1, preventing heat accumulation, and thus improving the heat dissipation performance of the energy storage cabinet. Optionally, the energy storage cabinet of this utility model also includes a cabinet door 8. The cabinet body 1 has an installation opening, and the cabinet door 8 is securely mounted to the installation opening via hinges or guide rail assemblies for easy maintenance.

[0032] Please see Figure 3 and Figure 4 In some embodiments, the cabinet 1 is provided with a baffle 11, which divides the cabinet 1 into a first accommodating chamber 1a for installing the fan 2 and a second accommodating chamber 1b for placing the battery module. In this embodiment, the air inlet 12 and the air outlet 13 are located on opposite sides of the baffle 11. Specifically, one of the air inlet 12 and the air outlet 13 is located in the portion of the wall panel corresponding to the first accommodating chamber 1a, and the other is located in the portion of the wall panel corresponding to the second accommodating chamber 1b.

[0033] In one embodiment, the cabinet 1 is generally rectangular, and a baffle 11 divides the cabinet 1 into the first receiving chamber 1a and the second receiving chamber 1b along the height direction of the cabinet 1. An air outlet 13 and an air inlet 12 are respectively located at the top and bottom of the cabinet 1. Specifically, the air outlet 13 and the air inlet 12 are located at the top of the first receiving chamber 1a and the bottom of the second receiving chamber 1b, respectively. A fan 2 is installed in the area corresponding to the air outlet 13 at the top of the first receiving chamber 1a. The placement of the air outlet 13 and the air inlet 12 at the top and bottom of the cabinet 1, compared to placing the air inlet 12 or the air outlet 13 in the middle of the cabinet 1 along its height direction, extends the airflow path, facilitates the even distribution of heat within the cabinet 1, reduces the risk of localized overheating, and allows for sufficient contact between ambient air and the battery module, improving heat exchange efficiency, removing the heat generated by the battery module, and thus extending the battery module's lifespan.

[0034] Example 1

[0035] In one embodiment, the baffle 1 is provided with a ventilation opening, and the first receiving chamber 1a is connected to the second receiving chamber 1b through the ventilation opening. Optionally, the baffle 1 is recessed on its surface to form a through ventilation opening, or there is a gap between one end of the baffle 1 and the wall panel of the cabinet 1 to form the ventilation opening. The baffle 1 facilitates the entry of external ambient air into the cabinet 1 through the air inlet 12 and allows it to fully contact the battery module, reducing the direct flow of ambient ambient air to the air outlet, which helps to improve heat exchange efficiency and thus enhance heat dissipation performance.

[0036] Example 2

[0037] Please see Figure 4 and Figure 5 Unlike Embodiment 1, the energy storage cabinet of this utility model also includes an air guide column 3, which is installed on the cabinet body 1. Specifically, the air guide column 3 is generally hollow in shape, and the first receiving chamber 1a is connected to the second receiving chamber 1b through the air guide column 3. Optionally, the air guide column 3 extends along the height direction of the cabinet body 1. During the operation of the fan 2, a negative pressure can be formed in the first receiving chamber 1a, thereby guiding the gas in the second receiving chamber 1b into the first receiving chamber 1a through the air guide column 3 and out through the air outlet 13, accelerating the gas flow speed in the second receiving chamber 1b, carrying away the heat generated by the battery module in the second receiving chamber 1b, thereby improving the heat dissipation performance of the energy storage cabinet.

[0038] In one embodiment, the air guide column 3 is disposed inside the cabinet 1, passes through the baffle 11, and is fixed to the wall panel of the cabinet 1 by fastener connection, snap-fit, welding, or other connection methods. Specifically, the air guide column 3 has an air guide channel 31 along its axial direction, and a first air vent 32 and a second air vent 33 are opened on its side. The first air vent 32 and the second air vent 33 are respectively connected to the air guide channel 31, and the first air vent 32 and the second air vent 33 are respectively located in the first receiving chamber 1a and the second receiving chamber 1b. During the operation of the energy storage cabinet, ambient temperature air from the external environment enters the second receiving chamber 1b and comes into full contact with the battery module. Afterward, it flows to the first receiving chamber 1a through the air guide column 3, improving heat exchange efficiency and helping to remove heat from the second receiving chamber 1b, thereby extending the service life of the battery module.

[0039] Optionally, a plurality of first vents 32 are spaced apart along the axial direction of the air guide column 3 at the portion of the air guide column 3 located in the first receiving chamber 1a, and a plurality of second vents 33 are spaced apart along the axial direction of the air guide column 3 at the portion of the air guide column 3 located in the second receiving chamber 1b. The air guide column 3 may be made of a nine-fold profile, which can save space, reduce costs, and improve the structural strength of the cabinet 1. It should be noted that the air guide column 3 may also be located on the outside of the cabinet 1.

[0040] Optionally, the number of air guide columns 3 is four, all extending along the height direction of the cabinet 1. The four air guide columns 3 are arranged in pairs opposite each other and fixedly connected to the wall panel of the cabinet 1. This facilitates the uniform flow of gas from the second receiving chamber 1b to the first receiving chamber 1a, further preventing local overheating. Furthermore, while the four air guide columns 3 connect the first receiving chamber 1a and the second receiving chamber 1b, they also enhance the structural strength of the cabinet 1 and save space. It should be noted that this invention does not limit the number of air guide columns 3. The number of air guide columns 3 can be two, and the two air guide columns 3 can be spaced apart along the length or width direction of the cabinet 1. The number of air guide columns 3 can also be four or more.

[0041] In some embodiments, the cabinet 1 is further provided with a mounting plate 4 for mounting a fan 2, and the mounting plate 4 is fixedly connected to the cabinet 1. Specifically, the mounting plate 4 is located in the first accommodating chamber 1a and is parallel to the baffle 11. The edge of the mounting plate 4 is fixed to the wall panel of the cabinet 1. The mounting plate 4 divides the first accommodating chamber 1a into an air outlet channel and an accommodating cavity for accommodating the fan 2. The mounting plate 4 has a ventilation hole 41 for connecting the air outlet channel and the accommodating cavity. The first vent 32 is located between the mounting plate 4 and the baffle 11. The fan 2 is disposed in the area corresponding to the ventilation hole 41 of the mounting plate 4.

[0042] Please see Figure 6 In one embodiment, a water baffle 5 is provided in the area corresponding to the air outlet 13 of the cabinet 1. The water baffle 5 includes a water baffle plate 51 and a mounting part 52. The water baffle plate 51 is fixed to the area corresponding to the air outlet of the cabinet 1 through the mounting part 52. There is a gap between the water baffle plate 51 and the cabinet 1 to allow gas flow. Optionally, the water baffle plate 51 protrudes from its edge toward the cabinet 1 to form a plurality of mounting parts 52. The mounting parts 52 are fixedly connected to the cabinet 1 by fastener connection, welding or snap-fit ​​connection.

[0043] In one embodiment, a guide plate 6 is provided on the side of the water baffle 5 near the air outlet 13 to guide the gas flow direction and prevent turbulence. Optionally, the guide plate 6 is frame-shaped, with the water baffle 5 protruding from its surface near the cabinet to form the guide plate 6, or the guide plate 6 includes a connecting plate and a guide portion, with the guide plate 6 bending and extending from the edge of the connecting plate toward the cabinet 1 to form the guide portion. The connecting plate is fixed to the surface of the water baffle 5 near the cabinet by welding, adhesive bonding, or fastener connection, etc., for easy installation.

[0044] In another embodiment, the middle portion of the water shield 5 protrudes away from its edge portion in a direction away from the cabinet 1 to form an air guide (not shown), which can also be used to guide the direction of gas flow and prevent turbulence.

[0045] Optionally, the mounting plate 4 extends from its corresponding ventilation hole 41 in a direction away from the cabinet 1 to form a water-blocking edge 15, further preventing rainwater or other liquids from entering the interior of the cabinet 1.

[0046] Please see Figure 7 In one embodiment, the bottom of the cabinet 1 is provided with a base 7. Optionally, the air outlet 13 is provided on the side wall of the base 7. In this embodiment, the air outlet 13 can also be used as a forklift hole for easy handling.

[0047] Optionally, the top of the base 7 is provided with a dustproof component 71, which has several heat dissipation holes, or the dustproof component 71 is mesh-like to prevent dust and other debris from entering the cabinet 1. Optionally, a filter layer is attached to the surface of the dustproof component 71. The filter layer can be made of non-woven fabric, polyester fiber, glass fiber, activated carbon, or other filter cotton materials. Understandably, the filter layer can also be directly set in the area of ​​the corresponding air inlet of the base 7.

[0048] The energy storage cabinet of this utility model also includes a temperature sensor and a controller (not shown) electrically connected to each other. The temperature sensor is located in the second housing chamber 1b and is used to detect the temperature of the battery module. The controller is also electrically connected to the fan 2 and is used to adjust the speed of the fan 2. In use, the temperature sensor is used to detect the temperature of the battery module in real time and send the temperature signal to the controller. When the temperature of the battery module is higher than a preset value, the controller can adjust the speed of the fan 2 to accelerate the air circulation speed inside the cabinet 1, introduce ambient air from the outside environment into the cabinet 1 through the air inlet 12 and exhaust it through the air outlet 13, thus removing heat from the cabinet 1. Furthermore, by adjusting the speed of the fan 2 through the controller, energy consumption can be reduced while ensuring heat dissipation.
