Description

Technical Field

[0001] This utility model relates to the field of internal heat dissipation battery compartment technology, specifically to an internal heat dissipation battery compartment. Background Technology

[0002] In today's era of energy transition and rapid technological development, batteries, as key energy supply components, are widely used in many fields, from portable electronic devices to electric vehicles and energy storage power stations. The battery case is a key container in the battery system that holds core components such as electrode plates and electrolytes, and its design directly affects the safety, performance and lifespan of the battery.

[0003] Currently, when using a battery compartment, the battery and other components are usually placed inside the compartment and then closed with a battery cover to ensure a waterproof seal between the compartment and the cover, preventing external water from entering and affecting its use.

[0004] However, when using the battery case, the sealed structure prevents the heat generated during charging and discharging from dissipating effectively. This poor heat dissipation can easily lead to thermal runaway and battery fires, affecting the battery's lifespan. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide an internal heat dissipation battery compartment to solve the technical problem that when the battery compartment is used, the heat generated by the charging and discharging inside the battery cannot be effectively dissipated due to the sealed structure of the battery compartment, resulting in poor battery heat dissipation, which can easily cause thermal runaway and lead to accidents such as battery fire, thus affecting the service life.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an internal heat dissipation battery compartment, comprising a battery compartment body, a battery cover connected to the top of the battery compartment body, a heat dissipation vent provided at the top of the battery compartment body, several sets of first heat dissipation fins fixedly connected around the battery compartment body, and several second heat dissipation fins fixedly connected to the bottom of the battery compartment body.

[0007] By adopting the above technical solution, heat inside the battery compartment can be discharged through the heat dissipation vents, allowing air circulation within the battery compartment and preventing heat accumulation inside. Simultaneously, the placement of the first and second heat dissipation fins around the battery compartment allows heat to be transferred to these fins, increasing the heat dissipation area and improving efficiency. This facilitates rapid heat transfer from the high-temperature battery compartment to the low-temperature air, achieving efficient heat dissipation, effectively reducing battery temperature, and preventing thermal runaway and fires. Furthermore, the design of the second heat dissipation fins allows the bottom of the battery compartment to be suspended, enabling air circulation and further improving heat dissipation efficiency.

[0008] The present invention is further provided that the surface of the battery compartment body is coated with a heat dissipation coating.

[0009] By adopting the above technical solution, the heat dissipation coating has good thermal conductivity, which can quickly conduct heat from inside the battery compartment to the outside, thereby enhancing the overall heat dissipation effect.

[0010] The present invention is further configured such that both the first heat dissipation fin and the second heat dissipation fin are connected to the battery compartment body by welding.

[0011] By adopting the above technical solution, the welding connection method can increase the strength of the connection between the first heat dissipation fin, the second heat dissipation fin and the battery compartment body, making the connection firm and reliable. This allows the heat in the battery compartment to be better transferred to the first or second heat dissipation fin for heat dissipation, thereby improving the heat dissipation efficiency.

[0012] The present invention is further configured such that the first heat dissipation fins in each group are configured with a cross-shaped structure.

[0013] By adopting the above technical solution, the first heat dissipation fin of the cross-shaped structure can increase its contact area with the air, thereby carrying more heat when the air flows, improving space utilization, and optimizing heat dissipation performance.

[0014] The present invention is further configured such that the second heat dissipation fin is configured as a wave-shaped structure.

[0015] By adopting the above technical solution, the wave-shaped second heat dissipation fins can increase their contact area with air and promote better airflow, which helps to improve heat dissipation efficiency.

[0016] In summary, the present invention has the following main advantages:

[0017] This invention allows heat to escape from the battery compartment through heat dissipation vents, preventing heat accumulation inside the battery compartment. Simultaneously, the placement of first and second heat dissipation fins around the battery compartment allows heat to be transferred to these fins, increasing the heat dissipation area and efficiency. This facilitates rapid heat transfer from the high-temperature battery compartment to the low-temperature air, achieving efficient heat dissipation, effectively reducing battery temperature, and preventing thermal runaway and fires. Furthermore, the design of the second heat dissipation fins allows the bottom of the battery compartment to be suspended, enabling air circulation and further improving heat dissipation efficiency.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] The embodiments of this utility model will be described below based on its overall structure.

[0025] Internal heat dissipation battery compartment, such as Figure 1-4 As shown, the device includes a battery compartment body 1, with a battery cover 2 connected to the top of the battery compartment body 1. Therefore, during use, the battery cover 2 can seal the battery compartment body 1, thereby protecting the batteries and other components inside and preventing water and other substances from affecting its service life.

[0026] Subsequently, a heat dissipation vent 3 is provided at the top of the battery compartment body 1, allowing heat inside the battery compartment body 1 to be discharged through the heat dissipation vent 3 from the connection point with the battery cover 2, preventing heat accumulation inside the battery compartment body 1. The design of the heat dissipation vent 3 here allows the connection point between the battery compartment body 1 and the battery cover 2 to not be completely fitted, thus preventing external water from entering the battery compartment body 1, without affecting heat dissipation. Several sets of first heat dissipation fins 4 are fixedly connected around the battery compartment body 1, and several sets of second heat dissipation fins 5 are fixedly connected to the bottom of the battery compartment body 1, allowing heat inside the battery compartment body 1 to be transferred to the air through the first heat dissipation fins 4 and the second heat dissipation fins 5, thereby increasing the heat dissipation area and improving heat dissipation efficiency. At the same time, the second heat dissipation fins are located at the bottom of the battery compartment body 1, making the battery compartment body 1 suspended, which facilitates better air circulation from the bottom and helps to improve heat dissipation efficiency.

[0027] The first heat dissipation fin 4 and the second heat dissipation fin 5 are both connected to the battery compartment body 1 by welding, which increases the firmness of the connection between the first heat dissipation fin 4 and the second heat dissipation fin 5 and the battery compartment body 1, and avoids affecting their service life. At the same time, each set of first heat dissipation fin 4 is set with a cross structure and the second heat dissipation fin 5 is set with a wave structure. Therefore, the cross structure of the first heat dissipation fin 4 and the wave structure of the second heat dissipation fin 5 can increase their contact area with air, thereby improving heat dissipation efficiency.

[0028] Furthermore, a heat dissipation coating, such as a metal heat dissipation coating, is applied to the surface of the battery compartment body 1. The heat dissipation coating has good thermal conductivity, which can quickly conduct the heat inside the battery compartment body 1 to the outside, thereby enhancing the overall heat dissipation effect.

[0029] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
