Description

Technical Field

[0001] This utility model relates to the field of battery swapping station technology, and in particular to a heat dissipation module for an outdoor battery storage cabinet. Background Technology

[0002] A lithium battery swapping cabinet is a device used to replace lithium batteries in electric vehicles. It typically consists of multiple storage compartments for lithium batteries. Users drive their electric vehicles into the cabinet, where robots or staff help remove the old battery and install the new one, completing the swapping process. The cabinet allows for rapid battery replacement, significantly reducing charging time and facilitating energy replenishment for electric vehicle users during long journeys. Furthermore, the cabinet can perform battery testing, charging, discharging, and management operations to ensure battery safety and performance. It is an important method for electric vehicle battery swapping, providing a more convenient, faster, and safer charging solution. However, existing battery swapping cabinet control systems have certain safety hazards in practical use and require frequent manual monitoring, impacting the system's usability. Therefore, a new technical solution is needed to address these issues.

[0003] Currently, Chinese patent CN221113846U discloses an intelligent management device for a battery swapping cabinet for lithium-ion electric vehicles. The device includes: a cabinet body; an internal mounting groove with fixed posts inside the groove; four sets of fixed posts fixedly connected to the mounting groove; a control plate with mounting holes inside the fixed posts; and mounting nuts on the surface of the fixed posts. This design ensures the stability of the control plate installation. Additionally, heat dissipation holes are provided on the back of the mounting groove, arranged in a strip-like, inclined pattern. This design facilitates heat dissipation while preventing dust ingress.

[0004] The existing technical solutions have the following drawbacks: during the charging process, the battery will emit a lot of heat, which cannot be dissipated in time through the heat dissipation holes, and the heat dissipation structure needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a heat dissipation module for an outdoor battery storage cabinet to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An outdoor battery storage cabinet heat dissipation module includes a battery swapping cabinet. An exhaust module is located at the rear of the battery swapping cabinet. Multiple battery swapping compartments are arranged in a rectangular row on the battery swapping cabinet. Each battery swapping compartment has a sealed door at its front. An air intake pipe and an exhaust pipe are installed inside the battery swapping cabinet. The exhaust pipe is connected to the exhaust module, which is used to create a negative pressure inside the battery swapping cabinet through the exhaust pipe. One end of the air intake pipe is connected to the outside of the battery swapping cabinet, and the air intake pipe is connected to each battery swapping compartment. Filter cotton cartridges are inserted at the points where the air intake pipe connects to each battery swapping compartment.

[0007] By adopting the above technical solution, since many battery swapping cabinets are installed outdoors in actual use, insulation and water resistance need to be considered. This inevitably requires the battery swapping cabinet to be set as a sealed structure. Therefore, a large amount of heat released by the battery during charging will accumulate inside the battery swapping cabinet. The common method is to use passive heat dissipation (opening a large number of heat dissipation holes and then setting a structure with heat dissipation holes to prevent rainwater from entering). Passive heat dissipation cannot solve the problem of large heat dissipation. This solution adopts an active heat dissipation structure, which accelerates the air flow through the exhaust module. Therefore, it is necessary to avoid the problem of excessive air humidity in rainy weather. This device uses filter cotton cylinders at each connected position to extract moisture. Generally speaking, no replacement is required. In rainy weather, the filter cotton cylinders absorb water vapor. On sunny or cloudy days, the heat emitted during the charging of the energy storage battery will dry the water vapor absorbed by the filter cotton cylinders.

[0008] In a further embodiment, the cross-section of the exhaust pipe is circular, and the cross-section of the intake pipe is rectangular.

[0009] By adopting the above technical solution, the rectangle is designed to better fit the structure of the battery swapping compartment, allowing the air intake pipe to make maximum use of the inner wall of the battery swapping compartment.

[0010] In a further embodiment, the rear side of the battery swapping compartment is a completely open structure, and the air intake pipe is used to completely block the rear side of the battery swapping compartment.

[0011] By adopting the above technical solution, the connection between the air extraction pipe and the battery swapping compartment is set at the top front of the battery swapping compartment, so that the airflow moves from back to front after entering the battery swapping compartment. Since the charging position of conventional energy storage batteries is set at the rear, the position that dissipates the most heat is also at the rear. This method makes full use of the heat exchange efficiency of the airflow.

[0012] In a further embodiment, the exhaust module is an axial flow fan.

[0013] By adopting the above technical solution, the axial flow fan has a strong suction capacity and is suitable for this solution. Because a filter cotton cylinder is inserted into the air inlet pipe of this solution, a high-power exhaust fan is required.

[0014] In a further embodiment, the door has a mesh structure, and a lifting plate is provided on the front side of the battery swapping compartment.

[0015] By adopting the above technical solution, the lifting plate can be opened when it is not raining, so that the mesh of the hatch can be utilized to improve heat dissipation efficiency and reduce the power consumption of the exhaust module. When it rains, the lifting plate is lowered to achieve a sealed treatment of the hatch.

[0016] In summary, this utility model has the following beneficial effects: 1. Since many battery swapping cabinets are installed outdoors in actual use, insulation and water resistance need to be considered. This inevitably requires the battery swapping cabinet to be designed as a sealed structure. Therefore, a large amount of heat released by the battery during charging will accumulate inside the battery swapping cabinet. The common method is to use passive heat dissipation (opening a large number of heat dissipation holes and then setting a structure with heat dissipation holes to prevent rainwater from entering). Passive heat dissipation cannot solve the problem of large heat dissipation. This solution adopts an active heat dissipation structure, which accelerates the air flow through the exhaust module. Therefore, it is necessary to avoid the problem of excessive air humidity in rainy weather. This device uses filter cotton cylinders at each connected position to extract moisture. Generally speaking, no replacement is required. In rainy weather, the filter cotton cylinders absorb water vapor. On sunny or cloudy days, the heat emitted during the charging of the energy storage battery will dry the water vapor absorbed by the filter cotton cylinders. Attached Figure Description
