Description

Technical Field

[0001] The present application relates to the field of energy storage, and in particular to an air-cooled energy storage battery cabinet. Background Art

[0002] In modern energy storage systems, air-cooled energy storage battery cabinets play a vital role. This device is mainly used to store and maintain battery packs, and its purpose is to ensure the stability of the battery and extend its service life through an effective cooling system. Usually, in order to reduce the operating temperature of the battery, the air cooling system uses air as the cooling medium and uses a single air conditioning system to push the hot air out from the inside of the battery cabinet.

[0003] However, when using a single air conditioning system for temperature control, especially in configurations dealing with multiple layers and multiple battery packs, such a system often cannot effectively achieve uniform heat dissipation inside the battery cabinet. The exhaust of hot air may cause heat dissipation blind spots to form inside the battery cabinet, especially in certain areas of the battery cabinet. These local heat dissipation blind spots can cause the battery pack to overheat, affecting its performance and safety.

[0004] Specifically, although the single air conditioning system can provide cooling in the central area, its overall air flow efficiency is low due to the air duct and structural design. Especially when the batteries are densely packed, the heat generated is high, or the external ambient temperature is high, this heat dissipation method often cannot effectively reduce the temperature inside the battery cabinet, and thus cannot achieve the ideal cooling effect.

[0005] In view of the shortcomings of the current air-cooled battery cabinet in using a single air conditioning system to achieve heat dissipation of multi-layer battery packs, it has become very necessary to develop a new type of air-cooled energy storage battery cabinet with higher efficiency and simpler structure. Utility Model Content

[0006] The purpose of the present application is to overcome at least one of the shortcomings of the prior art and to provide an air-cooled energy storage battery cabinet that uses a single cold air source to save costs, simplify the structure and achieve efficient heat dissipation.

[0007] To achieve the above-mentioned purpose, the present application discloses an air-cooled energy storage battery cabinet, comprising a cabinet body and a cold air component installed on one side of the cabinet body, wherein the cabinet body is open on one side, and the cold air component seals the cabinet body opening to form a sealed energy storage compartment; an air outlet is provided on the top of the cold air component, and a plurality of return air outlets are provided on the bottom; a refrigeration air conditioner is provided in the cold air component, and the air outlet end of the refrigeration air conditioner is opposite to the air outlet, and the air inlet end is opposite to each return air outlet; a plurality of support plates are provided in the cabinet body at intervals in the vertical direction, and a ventilation hole group is provided on the plate surface of the support plate, and a part of the cabinet space is vertically ventilated through the support plate It is divided into several compartments for rotating batteries, and each compartment is connected through a ventilation hole group; a front reserved position is reserved between the cold air component and each compartment, and a return air duct cooperating with the return air port is formed by using the reserved position, the return air duct is located in front of each compartment, and an air inlet duct opposite to the return air duct is formed behind each compartment through a reserved interval; the front of the top compartment in the cabinet is connected to the air outlet of the cold air component through an air inlet pipe, and an air guide connected to the air inlet duct is provided at the back, and the low-temperature airflow generated by the cold air component enters the air inlet duct from the top compartment through the air guide.

[0008] Specifically, the cabinet body is composed of a frame and a panel covering the cabinet frame.

[0009] Furthermore, the support plate is provided with a vertical plate at one end close to the return air duct, the support plate is provided with at least one opening, and a negative pressure fan is installed at each opening, and the negative pressure fan guides the airflow from one side of the air inlet duct to the return air duct.

[0010] Compared with the prior art, the present invention has at least one of the following beneficial effects:

[0011] 1. The battery cabinet uses a single cold air source and achieves efficient air flow through optimized air duct design. Compared with the traditional single air conditioning system, this design effectively avoids the formation of internal heat dissipation blind spots, thereby distributing cold air more evenly and ensuring that each battery pack can be effectively cooled.

[0012] 2. The design simplifies the structural complexity and reduces the need to use multiple cooling devices, thereby reducing energy consumption and initial investment costs. The use of a single cold air source combined with efficient air circulation achieves lower operating costs and is an energy-saving and economical solution.

[0013] 3. By providing more uniform and effective cooling, the new battery cabinet can reduce performance degradation and safety risks caused by battery overheating, thereby extending the service life of the battery pack and enhancing its stability.

[0014] 4. The design of the battery cabinet includes several vertical support plates and ventilation hole groups, as well as the use of space to create specific air inlet and return air ducts. This structure not only optimizes air circulation, but also provides possibilities for future expansion and modularization.

[0015] 5. By concentrating all cooling air components on one side of the cabinet and designing easy-to-access air ducts and fans, the maintenance and upgrade of the new battery cabinet becomes easier, reducing maintenance costs and time. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figures 1 to 4An exemplary structure for achieving the technical purpose of the present application is shown. As shown in the figure, the air-cooled energy storage battery cabinet in this embodiment includes a cabinet body 1 made of metal material. The outer surface of the cabinet body 1 is covered with a protective insulating material panel 2 to improve safety and durability. A single opening is opened on one side of the cabinet body 1, and the opening is completely sealed by a cold air component 3, thereby forming a closed energy storage bin.

[0029] In this embodiment, the cold air assembly 3 is installed on the side opening of the cabinet 1, and a refrigeration and air conditioning system is built in. The air outlet of the refrigeration and air conditioning is aligned with an air outlet 4 on the upper side of the cold air assembly 3, and the air inlet is aligned with a plurality of return air ports 5 arranged on the side of the cold air assembly 3. This configuration ensures that cold air can be delivered from the top, while hot air flows back from one side, forming an effective air circulation.

[0030] More specifically, a plurality of support plates 6 are arranged vertically inside the cabinet 1, and each support plate 6 is provided with a ventilation hole group 7. The support plates 6 divide the interior of the cabinet 1 into a plurality of compartments 8, and each compartment 8 is used to store one or more groups of batteries 9. The compartments 8 are interconnected through the ventilation hole group 7 on the support plates 6, ensuring that hot and cold air can flow freely to prevent local overheating.

[0031] More specifically, in front of each compartment 8, a front reserved space is reserved between the cold air assembly 3 and the compartment 8, and the reserved space is used to form a return air duct 10 that cooperates with the return air port 5. The design of the return air duct 10 ensures that hot air can be effectively drawn out of the compartment 8 and re-cooled. In addition, an air inlet duct opposite to the return air duct is formed at a certain interval behind each compartment 8, further optimizing the air flow circulation.

[0032] More specifically, an air inlet duct 11 is provided in front of the uppermost compartment in the cabinet 1, and the air inlet duct 11 is directly connected to the air outlet 4 of the cold air assembly 3. An air guide 12 is provided behind the compartment 8 for guiding cold air into the air inlet duct.

[0033] In some embodiments, each support plate 6 is also equipped with at least one negative pressure fan 13 near one end of the return air duct 10. These negative pressure fans 13 help to enhance the circulation of air flow, push the cold air into the compartment 8 more effectively, and accelerate the discharge of hot air.

[0034] Although the exemplary embodiments of the present disclosure have been described, it should be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without departing from the spirit and scope of the present disclosure in essence. Therefore, all changes and modifications are included in the scope of protection of the present disclosure as defined by the claims. The present disclosure is defined by the appended claims, and the equivalents of these claims are also included.
