Technical Field

[0001] The utility model relates to the technical field of battery swapping cabinets, in particular to a heat dissipation device for a battery swapping cabinet. Background Art

[0002] As an innovative urban convenient charging solution, electric vehicle battery swapping cabinets are widely distributed at street corners, residential communities and commercial areas in the city, effectively alleviating the problem of difficult charging of electric vehicles. These intelligent battery swapping cabinets are usually equipped with advanced battery management systems, which can finely manage the stored batteries, including charging status, power monitoring and health status assessment. Through the integrated communication technology, the battery swapping cabinet can be seamlessly connected with the user's mobile phone APP, the electric vehicle system and the remote background, realizing functions such as quickly locating idle batteries, reserving battery swapping and online payment. Its mechanical design not only ensures the easy plugging and unplugging of the battery and high anti-theft performance, but also takes into account the requirements of waterproof and dustproof, adapting to various outdoor environments.

[0003] However, there is a significant technical challenge in the existing battery swapping cabinet technology: poor heat dissipation effect. Since the charging batteries are densely stored in the cabinet and continuous power conversion occurs, heat accumulates inside. Especially under high-frequency use, the temperature inside the cabinet rises sharply, which not only affects the charging efficiency and lifespan of the batteries, but also may pose safety hazards. Therefore, how to optimize the heat dissipation system of the battery swapping cabinet to ensure that the batteries are charged within a safe temperature range has become an urgent problem to be solved.

[0006] The technical principle of the utility model is as follows: by setting the heat dissipation structure, the original air heat conduction is changed to object medium heat conduction, such as copper, aluminum, etc., and then the heat can be quickly guided to the exhaust device at the top, and then the heat is quickly discharged through the exhaust device.

[0007] Compared with the prior art, the utility model has the following beneficial effects: the heat of the battery swapping cabinet is quickly guided and discharged through the cooperation of the heat dissipation structure and the exhaust device, avoiding the concentration of heat in the battery swapping cabinet. Compared with the traditional air heat dissipation, the heat dissipation efficiency is doubled, and the technical problem of poor heat dissipation effect existing in the existing battery swapping cabinets is solved.

[0021] The technical solutions in the present utility model will be further described below in conjunction with the drawings and embodiments.

[0022] Example 1

[0023] As Figure 1-2 shown in the battery swapping cabinet heat dissipation device, the battery swapping cabinet includes a housing 10 and battery swapping bins 11 evenly distributed in the housing 10. A main control circuit board 12 is further provided at the top of the housing 10, and the main control circuit board 12 is arranged at a position near the front side of the top of the housing 10.

[0024] As Figure 1-3 shown, heat dissipation structures 20 are fixed to the top and both side surfaces of the housing 10 and are interconnected.

[0025] Specifically, the heat dissipation structures 20 on both side surfaces of the housing 10 include a plurality of vertical fins 21 and horizontal fins 22. All the vertical fins 21 are vertically and evenly distributed on both sides of the housing 10 to form a plurality of upward channels. All the horizontal fins 22 are horizontally arranged. The vertical fins 21 and the horizontal fins 22 are both parallel to the rear side surface of the housing 10. Both ends of each horizontal fin 22 are respectively connected to the vertical fins 21 on both sides. Among them, vertically distributed vertical fins 21 are also fixed between two vertically arranged battery swapping bins 11, and the tops of the vertical fins 21 are connected to the horizontal fins 22 for heat dissipation at the position between the two rows of battery swapping bins 11.

[0026] Specifically, the heat dissipation structure 20 on the top of the housing 10 includes evenly distributed guiding heat dissipation fins 23. The guiding heat dissipation fins 23 are all perpendicular to the rear side surface of the housing 10 to form an exhaust air channel. The bottoms of the guiding heat dissipation fins 23 are connected to the horizontal fins 22, so that the upward channels and the exhaust air channel can be communicated. At the same time, the heat dissipation structures 20 on the top and both sides of the housing 10 can conduct heat to each other. The guiding heat dissipation fins 23 are perpendicular to the main control circuit board 12 for discharging the heat of the main control circuit board 12.

[0027] As Figure 3-4 shown, an exhaust device 30 is provided at the rear side of the top of the housing 10. The exhaust device 30 is aligned with the guiding heat dissipation fins 23 to discharge the air in the exhaust air channel. Specifically, the exhaust device 30 includes a fixing plate 31 and an exhaust fan 32. Among them, the fixing plate 31 is fixed on the housing 10, and the fixing plate 31 is arranged to be inclined upward. Exhaust holes 33 are evenly distributed on the fixing plate 31, and an exhaust fan 32 is installed on each exhaust hole 33. The upward inclination is because after the heat is dissipated into the air in the exhaust air channel, the hot air has a small density and will float to the top of the housing 10. After the upward inclination is set, the hottest air can be accurately discharged.

[0028] As Figure 2-3 shown, an air inlet 13 is provided at a position near the bottom of the housing 10, and an air outlet 14 is provided at the position of the housing 10 where the exhaust device 30 is located, forming a complete air circulation.

[0029] Example 2

[0030] As Figure 5As shown in the figure, the difference between this embodiment and Embodiment 1 is that: there is also an air outlet 14 at the top of the outer shell 10, allowing the hot air in the exhaust air passage to float upward naturally due to density and be discharged. However, after the air outlet 14 is provided at the top, it is easy for rainwater to enter. Therefore, a rain shelter 15 needs to be provided at the top of the outer shell 10 to block the rainwater.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
