Description

Technical Field

[0001] This utility model relates to the field of storage batteries, and in particular to a storage battery heat dissipation structure. Background Technology

[0002] A storage battery is an electrochemical device that can reversibly convert chemical energy into electrical energy. It stores electrical energy through specific chemical reactions and releases the stored chemical energy back into electrical energy when needed. After discharging, it can be replenished by an external power source to restore the internal chemical substances to their initial state, thus enabling multiple charge-discharge cycles rather than single-use.

[0003] Existing battery cooling methods are mainly divided into two categories: active and passive. Active cooling requires external energy input, and common methods include air cooling and liquid cooling. Passive cooling does not require external energy and includes natural convection and the application of thermal insulation materials. In practical applications, different cooling methods are often selected or combined based on the battery type, power density, and usage scenario to ensure stable operation.

[0004] During the use of batteries, the heat dissipation effect directly affects their working stability and service life. Some heat dissipation mechanisms have unreasonable air duct design, which makes it difficult for cold air to cover the battery evenly. This can easily lead to insufficient cold air supply in some areas. Furthermore, they cannot effectively cooperate with the heat dissipation structure to form an efficient convection circulation, resulting in the heat generated by the battery during operation not being able to be dissipated quickly and smoothly. Therefore, a battery heat dissipation structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a battery heat dissipation structure, which aims to solve the problem that the existing battery heat dissipation mechanism has unreasonable air duct design, resulting in difficulty in uniformly covering the battery with cold air and insufficient cold air supply in some areas.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a battery heat dissipation structure, including a heat dissipation fixing frame, a heat dissipation mechanism and a heat exhaust mechanism are provided on the inner wall of the heat dissipation fixing frame, a battery is provided on the inner wall of the heat dissipation fixing frame, the heat dissipation mechanism includes an air guide plate, the outer wall of the air guide plate is rotatably connected to the inner wall of the heat dissipation fixing frame, a gear is fixedly connected to the outer wall of the air guide plate, a rack is meshed with the outer wall of the gear, a U-shaped plate is fixedly connected to the top of the rack, a support plate is fixedly connected to the inner wall of the heat dissipation fixing frame, a triangular connecting plate is fixedly connected to the outer wall of the support plate, a ring tooth is rotatably connected to the outer wall of the support plate, a circular plate is fixedly connected to the outer wall of the ring tooth, an extrusion rod is fixedly connected to the outer wall of the circular plate, and the outer wall of the extrusion rod is slidably connected to the inner surface of the U-shaped plate.

[0007] As a further description of the above technical solution: The heat dissipation mechanism also includes a motor, the outer wall of which is fixedly connected to the inner wall of the triangular connecting plate.

[0008] As a further description of the above technical solution: The heat dissipation mechanism also includes a cooling fan, the outer wall of which is fixedly connected to the motor output shaft.

[0013] As a further description of the above technical solution: The heat dissipation mechanism also includes a heat dissipation port, which is located on the outer wall of the heat dissipation fixing frame.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by setting up a heat dissipation mechanism, the dual functions of heat dissipation fan air delivery and dynamic adjustment of air guide plate are realized by a single motor drive. The cold air evenly covers all areas of the battery within the heat dissipation fixing frame, and forms an efficient convection circulation with the heat dissipation channel and heat dissipation port, effectively avoiding local overheating and sudden temperature rise.

[0015] 2. In this utility model, by setting up a heat dissipation mechanism, the heat dissipation channel and the heat dissipation port in the heat dissipation mechanism are interconnected, forming a smooth heat dissipation path. When the cold air in the heat dissipation fixing frame absorbs the heat emitted by the battery, the hot air can be quickly discharged to the outside of the equipment under the guidance of the channel and the heat dissipation port, effectively avoiding damage to the battery performance due to high temperature and ensuring its stable operation.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3The present invention provides an embodiment of a battery heat dissipation structure, comprising a heat dissipation fixing frame 1, a heat dissipation mechanism 2 and a heat exhaust mechanism 3 disposed on the inner wall of the heat dissipation fixing frame 1, the heat dissipation mechanism 2 providing a source of cold air and a uniform airflow function for cooling the battery 4, and the heat exhaust mechanism 3 dissipating the heat absorbed by the battery 4 inside the heat dissipation fixing frame 1. The battery 4 is disposed on the inner wall of the heat dissipation fixing frame 1. The heat dissipation mechanism 2 includes an air guide plate 211, which can change the flow direction of the cold air in the heat dissipation fixing frame 1 by reciprocating left and right, ensuring that the cold air evenly covers the surface of the battery 4. The outer wall of the air guide plate 211 is rotatably connected to the inner wall of the heat dissipation fixing frame 1. A gear 212 is fixedly connected to the outer wall of the air guide plate 211. The gear 212 can reciprocate in both directions under the drive of the rack 213, thus providing power for the left-right reciprocating movement of the air guide plate 211. The outer wall of the gear 212 is meshed with the rack 213, which can move synchronously with the horizontal reciprocating movement of the return plate 214, thereby driving the gear 212 to rotate. The top of the rack 213 is fixedly connected to the return plate 214, which can be pressed by the extrusion rod 219. The horizontal reciprocating motion drives the rack 213 to move synchronously. A support plate 215 is fixedly connected to the inner wall of the heat dissipation frame 1, providing support for the ring gear 217 and ensuring its stability during rotation. A triangular connecting plate 216 is fixedly connected to the outer wall of the support plate 215, providing stable mounting support for both the motor 220 and the gear 223, ensuring stable meshing transmission between gear 222 and gear 223 when the output shaft of the motor 220 rotates. A ring gear 217 is rotatably connected to the outer wall of the support plate 215. 217 can rotate under the drive of gear 223, which in turn drives the circular plate 218 to rotate synchronously. The circular plate 218 is fixedly connected to the outer wall of the ring gear 217. The circular plate 218 can drive the extrusion rod 219 to make eccentric circular motion as the ring gear 217 rotates, providing a motion basis for extruding the return plate 214. The extrusion rod 219 is fixedly connected to the outer wall of the circular plate 218. The extrusion rod 219 can continuously extrude the inner surface of the return plate 214 through eccentric circular motion, pushing the return plate 214 to move horizontally back and forth. The outer wall of the extrusion rod 219 is slidably connected to the inner surface of the return plate 214.

[0020] Reference Figures 4-6The heat dissipation mechanism 2 also includes a motor 220. The output shaft of the motor 220 can simultaneously drive the cooling fan 221 and the gear 222 to rotate. The outer wall of the motor 220 is fixedly connected to the inner wall of the triangular connecting plate 216. The heat dissipation mechanism 2 also includes a cooling fan 221, which can rotate under the drive of the output shaft of the motor 220, guiding external cold air into the heat dissipation frame 1 to provide cool air for cooling the battery 4. The outer wall of the cooling fan 221 is fixedly connected to the output shaft of the motor 220. The heat dissipation mechanism 2 also includes a gear 222, which can rotate with the motor. The output shaft of motor 220 rotates synchronously, thereby driving the gear 223 meshing with it to rotate, thus realizing power transmission. The inner wall of gear 222 is fixedly connected to the outer wall of the output shaft of motor 220. The heat dissipation mechanism 2 also includes gear 223. Gear 223 can rotate under the drive of gear 222, and at the same time drive the ring gear 217 meshing with it to rotate, playing the role of power transfer. The outer wall of gear 223 is rotatably connected to the outer wall of triangular connecting plate 216. The outer wall of gear 223 is meshed with the outer wall of ring gear 217 and the outer wall of gear 222 respectively.

[0021] Reference Figure 7 The heat dissipation mechanism 3 includes a heat dissipation channel 311, which provides a flow path for the heat inside the heat dissipation frame 1, allowing the heat to flow smoothly to the heat dissipation port 312. The heat dissipation channel 311 is opened on the inner wall of the heat dissipation frame 1. The heat dissipation mechanism 3 also includes a heat dissipation port 312, which can discharge the heat inside the heat dissipation frame 1 that flows through the heat dissipation channel 311 to the external environment, completing the heat dissipation cycle. The heat dissipation port 312 is opened on the outer wall of the heat dissipation frame 1.

[0022] Working principle: When it is necessary to dissipate heat from the battery 4, the motor 220 can be started, causing the output shaft of the motor 220 to drive the fixedly connected cooling fan 221 to rotate. This guides external cold air into the heat dissipation frame 1, thereby cooling the battery 4. Simultaneously, the rotation of the motor 220's output shaft drives gear 222 to rotate, which in turn drives gear 223, which is meshed with the outer wall of gear 223, to rotate. This, in turn, drives the ring gear 217, which is meshed with the outer wall of gear 223, to rotate. The support plate 215 provides support for the rotating ring gear 217, which in turn drives the external... The circular plate 218, which is fixedly connected to the wall, rotates, and the circular plate 218 drives the extrusion rod 219 to perform eccentric circular motion. The extrusion rod 219 extrudes the molded plate 214 to move horizontally back and forth, causing the rack 213, which is fixedly connected to the bottom of the molded plate 214, to move synchronously. The rack 213 drives the gear 212, which is meshed with the outer wall, to rotate back and forth. Thus, the gear 212 drives the air guide plate 211 to move left and right back and forth, so that the cold air is evenly covered in the heat dissipation fixed frame 1. The heat inside the heat dissipation fixed frame 1 can be discharged through the heat dissipation channel 311 and the heat dissipation port 312.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
