Battery energy storage container air-cooling heat dissipation structure

Abstract

This utility model discloses a battery energy storage container air-cooled heat dissipation structure, including: a container body; a support frame, which is fixedly installed on one outer wall of the container body; and a shell, which is fixedly installed on the support frame. Compared with the prior art, the air-cooling mechanism utilizes a semiconductor cooling chip array to cool the intake air, thereby lowering the temperature of the air entering the container body and more effectively cooling the battery modules, significantly improving the heat dissipation effect. Through the design of a guide shroud, three ventilation ducts, and air boxes, the guide shroud can initially guide the cold air output by the fan, making the airflow more concentrated and orderly. The three ventilation ducts distribute the cold air to two air boxes, ensuring that the battery modules on each mounting rack receive appropriate cooling airflow. The air boxes precisely guide the distributed cold air to the battery modules on the mounting rack, achieving precise air-cooled heat dissipation for the battery modules.

Description

Technical Field

[0001] This utility model relates to the field of energy storage container technology, and in particular to a wind-cooled heat dissipation structure for a battery energy storage container. Background Technology

[0002] With the rapid development of new energy technologies, battery energy storage systems are widely used in fields such as power storage and distributed energy. Battery energy storage containers, as an integrated battery energy storage device, have advantages such as convenient installation and portability. However, during the operation of battery energy storage containers, the batteries generate a large amount of heat. If this heat cannot be dissipated effectively and in a timely manner, it can lead to excessively high battery temperatures, affecting battery performance and lifespan, and may even cause safety accidents.

[0003] Currently, battery storage containers typically employ air cooling, which involves drawing outside air into the container using fans and using airflow to dissipate the heat generated by the batteries. However, in high-temperature environments, the outside air temperature is too high, and the air drawn into the container cannot effectively lower the battery temperature, resulting in poor heat dissipation. Utility Model Content

[0004] The main purpose of this invention is to propose a wind-cooled heat dissipation structure for battery energy storage containers, which can effectively solve the problems in the background technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a battery energy storage container air-cooled heat dissipation structure, comprising:

[0006] The container itself;

[0007] The bracket is fixedly installed on one side of the outer wall of the container body;

[0008] A housing, which is fixedly mounted on a bracket;

[0009] A chassis, which is fixedly mounted on one outer wall of the shell, and a fan is installed inside the chassis, which is connected to the shell;

[0010] Two mounting brackets are respectively fixedly installed on both sides of the interior of the container body;

[0011] A bellows, which is fixedly mounted on a mounting frame;

[0012] An air-cooling mechanism is installed inside the housing and is used to cool the air to dissipate heat from the battery module on the mounting bracket.

[0013] As a further description of the above technical solution, the air-cooling mechanism includes a mounting plate, which is fixedly disposed between the inner walls of both sides of the housing. A semiconductor refrigeration chip assembly is mounted on the mounting plate. A cooling block is fixedly connected to the lower side wall of the mounting plate. The cooling block is in contact with the cold surface of the semiconductor refrigeration chip assembly and is coated with thermal grease. Several heat exchange grooves are formed on the cooling block.

[0014] As a further description of the above technical solution, a heat sink is fixedly connected to the upper side wall of the mounting plate, and the heat sink is in contact with the hot surface of the semiconductor cooling chip assembly and is coated with thermal grease.

[0015] As a further description of the above technical solution, three ventilation ducts are fixedly provided on one inner wall of the container body, and both air boxes are connected to the three ventilation ducts. A flow guide is connected to the side wall of the shell near the container body, and the flow guide is connected to the three ventilation ducts.

[0016] As a further description of the above technical solution, multiple sets of air outlets are evenly opened on the side wall of the air box facing the mounting frame.

[0017] As a further description of the above technical solution, the heat exchange groove is a serpentine groove.

[0018] As a further description of the above technical solution, a dustproof net is provided on one side wall of the chassis.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. By using a set air-cooling mechanism and semiconductor cooling chips to cool the intake air, the temperature of the air entering the container body is reduced, which can more effectively cool the battery module, significantly improve the heat dissipation effect, and solve the problem of poor heat dissipation when the ambient temperature is high.

[0021] 2. Through the design of the air guide shroud, three ventilation ducts, and air boxes, the air guide shroud can initially guide the cold air output by the fan, making the airflow more concentrated and orderly. The three ventilation ducts distribute the cold air volume to the two air boxes, ensuring that the battery modules on each mounting rack can receive appropriate cooling airflow. The air boxes then precisely guide the distributed cold air to the battery modules on the mounting rack, achieving precise air cooling of the battery modules. Attached Figure Description

Detailed Implementation

[0029] To make the technical means, creative features, and objectives of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments.

They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Please see Figure 1-6This utility model provides a battery energy storage container air-cooled heat dissipation structure, including:

[0033] Container body 1;

[0034] Support 2 is fixedly installed on one side of the outer wall of the container body 1;

[0035] Housing 3 is fixedly mounted on bracket 2;

[0036] The chassis 4 is fixedly mounted on one side of the outer wall of the housing 3. The chassis 4 is equipped with a fan 41 and is connected to the housing 3.

[0037] Two mounting brackets 5 are fixedly installed on both sides of the interior of the container body 1;

[0038] The bellows 6 is fixedly mounted on the mounting bracket 5;

[0039] The air-cooling mechanism 7 is installed inside the housing 3. The air-cooling mechanism 7 is used to cool the air and then dissipate heat from the battery module on the mounting bracket 5.

[0040] The above structure enables efficient heat dissipation of the battery module.

[0041] The air-cooling mechanism 7 includes a mounting plate 71, which is fixedly disposed between the inner walls of both sides of the housing 3. A semiconductor cooling chip assembly 72 is mounted on the mounting plate 71. A cooling block 73 is fixedly connected to the lower side wall of the mounting plate 71. The cooling block 73 is in contact with the cold surface of the semiconductor cooling chip assembly 72 and is coated with thermal grease. Several heat exchange grooves 74 are formed on the cooling block 73.

[0042] By using the above structure, the semiconductor cooling chip group 72 is used to cool the intake air, thereby reducing the temperature of the air entering the container body 1. This can more effectively cool the battery module, significantly improve the heat dissipation effect, and solve the problem of poor heat dissipation when the ambient temperature is high.

[0043] A heat sink 711 is fixedly connected to the upper side wall of the mounting plate 71. The heat sink 711 is in contact with the hot surface of the semiconductor cooling chip assembly 72 and is coated with thermal grease.

[0044] The above structure enables heat dissipation from the semiconductor cooling chip 72, ensuring its normal cooling operation.

[0045] Among them, a three-ventilation duct 8 is fixedly installed on one inner wall of the container body 1, and two air boxes 6 are connected to the three-ventilation duct 8. A flow guide 31 is connected to the side wall of the shell 3 near the container body 1, and the flow guide 31 is connected to the three-ventilation duct 8.

[0046] With the above structure, the air guide shroud 31 can initially guide the cold air output by the fan 41, making the airflow more concentrated and orderly. The three ventilation ducts 8 can reasonably distribute the cold air volume to the air box 6 to ensure that the battery modules on each mounting bracket 5 can receive appropriate cooling airflow. The air box 6 then accurately guides the distributed cold air to the battery modules on the mounting bracket 5, realizing precise air cooling heat dissipation of the battery modules.

[0047] Multiple sets of air outlets 61 are evenly opened on the side wall of the bellows 6 facing the mounting frame 5, and the cold air in the bellows 6 is discharged through the air outlets 61.

[0048] Among them, the heat exchange groove 74 is a serpentine groove, which guides the outside air to flow in a meandering manner within the heat exchange groove 74, increases the contact time between the outside air and the cooling block 73, and ensures that the outside air can be effectively cooled.

[0049] The casing 4 has a dustproof net 42 on one side wall, which can filter the outside air and prevent dust from entering the container body 1.

[0050] It should be noted that this utility model is a battery energy storage container air-cooled heat dissipation structure. When in use, the fan 41 is started to draw in outside air. The air first passes through the dustproof net 42 to filter out dust and other impurities, and then passes through the air-cooling mechanism 7. The semiconductor refrigeration chip group 72 cools the cooling block 73. When the air passes through the heat exchange tank 74, it is cooled into cold air, and then enters the three ventilation pipes 8 through the guide shroud 31. The three ventilation pipes 8 deliver the cold air to the two air boxes 6 respectively. The cold air is discharged through the air outlet 61 on the air box 6 to the battery module on the mounting frame 5 to dissipate heat and cool the battery module.

[0051] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
