[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a photovoltaic energy storage cabinet, comprising:

[0006] Cabinet;

[0007] Multiple guide rail assemblies are installed sequentially in the cabinet along the vertical direction;

[0008] Multiple battery module mounting cabinets, which are slidably mounted on the guide rail assembly;

[0009] A side ventilation duct is fixedly installed inside the cabinet. The lower end of the side ventilation duct is provided with an air inlet, the upper end with an air outlet, and the side wall of the side ventilation duct is provided with an exhaust port.

[0010] An air intake assembly is installed at the bottom of the cabinet, at a position corresponding to the air intake of the bypass ventilation duct;

[0012] At least one exhaust fan mounting mechanism, which is detachably mounted on the guide frame through the connecting hole;

[0013] An exhaust fan is mounted on the exhaust fan mounting mechanism.

[0014] Furthermore, the exhaust fan mounting mechanism includes: a mounting bracket and a fan mounting block, wherein:

[0015] The mounting bracket is provided with a fixed part and a connecting part connected together. The fixed part includes a pair of guide cylinders, which are adapted to pass through the connecting holes of the guide bracket.

[0016] The fan mounting block is provided with a connecting groove that slides with the connecting part of the mounting bracket, and the fan mounting block is adapted to move along the length direction of the connecting part of the mounting bracket.

[0017] Furthermore, the fan mounting block is provided with mounting holes suitable for installing an exhaust fan.

[0018] Furthermore, the photovoltaic energy storage cabinet also includes a locking block, which has a locking groove that cooperates with the fixing part of the mounting bracket;

[0020] The locking block is adapted to be fixed on the mounting bracket by fasteners passing sequentially through the second threaded hole and the first threaded hole.

[0021] Furthermore, the bypass ventilation duct is provided with an air inlet guide section, a vertical air duct section, and an air outlet guide section in sequence from bottom to top along the vertical direction, wherein:

[0022] One end of the air inlet guide section is connected to the air inlet, and the other end is connected to the bottom of the vertical air duct section;

During operation, the bottom air inlet component blows cool air into the bypass ventilation duct, forming a complete main air duct through the air inlet, vertical duct, and outlet of the bypass ventilation duct. The exhaust fan on the mounting mechanism guides hot air around the battery module into the main air duct through the exhaust port of the bypass ventilation duct. The vertical duct utilizes the natural upward movement of hot air to create natural convection through temperature difference, ensuring that even when the fan stops running, the temperature difference effect continues to assist airflow and continuously enhance heat dissipation. This not only achieves efficient heat dissipation for the battery module but also effectively avoids potential safety hazards caused by fan damage.

[0030] In addition, the exhaust fan installation mechanism adopts a combination design of installation connecting frame and fan mounting block, which allows the installation position of the exhaust fan to be flexibly adjusted according to the actual operating conditions.

[0040] Cabinet 1;

[0041] Eight guide rail assemblies are installed vertically in the cabinet 1.

[0042] Eight battery module mounting cabinets 3 are slidably mounted on the guide rail assembly.

[0043] Side ventilation duct 6 is fixedly installed inside cabinet 1. The lower end of the side ventilation duct 6 is provided with an air inlet, the upper end with an air outlet, and the side wall of the side ventilation duct 6 is provided with an exhaust port.

[0044] Air intake component 4 is installed at the bottom of cabinet 1, at the position corresponding to the air intake of the bypass ventilation duct 6.

[0048] In this embodiment, as Figure 1-3 As shown, the exhaust fan mounting mechanism 7 can be flexibly installed at different heights on the guide frame 5 according to actual heat dissipation needs. When running, the bottom air inlet component 4 blows cool air into the bypass ventilation duct 6, forming a complete main air duct through the air inlet, vertical air duct, and air outlet of the bypass ventilation duct 6. The exhaust fan on the exhaust fan mounting mechanism 7 guides the hot air around the battery module into the main air duct through the exhaust port of the bypass ventilation duct 6. The vertical air duct utilizes the natural rising characteristic of hot air to form natural convection through temperature difference, ensuring that even when the fan stops running, the temperature difference effect can still assist airflow and continuously enhance the heat dissipation effect. This not only achieves efficient heat dissipation of the battery module but also effectively avoids potential safety hazards caused by fan damage.

[0049] Specifically, such as Figure 1 and Figure 4 and Figure 6 As shown, the exhaust fan mounting mechanism 7 includes: a mounting bracket 71 and a fan mounting block 72, wherein:

The mounting bracket 71 is securely connected to the guide bracket 5 via a pair of guide cylinders and the connecting holes 51, while the fan mounting block 72 can slide along the connecting part of the mounting bracket 71. This allows the exhaust fan's mounting position to be adjusted according to actual heat dissipation requirements.

[0057] The locking block 73 engages with the fixing part of the mounting bracket 71 through the locking groove, and is connected to the fasteners of the first threaded hole and the second threaded hole, forming a stable locking structure.

[0058] Specifically, such as Figure 1 and Figure 3 As shown, the bypass ventilation duct 6 is provided with an air inlet guide section, a vertical duct section, and an air outlet guide section from bottom to top in the vertical direction, wherein:

[0059] One end of the air inlet guide section is connected to the air inlet, and the other end is connected to the bottom of the vertical air duct section;

[0060] The vertical air duct section extends vertically, and the exhaust port is located on the side wall of the vertical air duct section. The vertical air duct section is located between the exhaust fan mounting mechanism 7 and the inner wall of the cabinet 1.

[0061] One end of the air outlet guide section is connected to the top of the vertical air duct section, and the other end passes through the cabinet 1 and is connected to the outside. The air outlet is located on the other end of the air outlet guide section.

[0063] The exhaust vents on the side wall of the vertical air duct section correspond to the positions of the exhaust fans. A baffle is provided at the corresponding position of the exhaust vent in the side ventilation duct 6, and the baffle is set at an angle upward.

[0064] Specifically, such as Figure 1-2 As shown, the air intake assembly 4 includes six fan groups installed at the bottom of the cabinet 1;

[0065] The fan assembly directs airflow towards the interior of cabinet 1.

[0066] Specifically, such as Figure 1-2 As shown, the battery module mounting cabinet 3 is equipped with a pair of handle assemblies 31.
