Description

Technical Field

[0001] This utility model relates to the field of aging cabinets, specifically a mobile power bank aging cabinet. Background Technology

[0002] Aging testing is a crucial step in the battery manufacturing process for power banks. It simulates long-term charge-discharge cycles and high-temperature environments to test battery stability, capacity decay, and safety performance. In the production and testing of power banks, aging testing is a key step in ensuring product quality and performance stability. The aging chamber, as the main equipment for aging testing, directly affects the efficiency and effectiveness of the test through its internal structural design.

[0003] Traditional power bank aging cabinets typically employ a monolithic enclosure structure, relying on a single cooling fan or simple ventilation holes for heat exchange. This design suffers from several technical drawbacks: First, the lack of independent air ducts leads to disordered hot air circulation within the cabinet, causing localized temperature buildup (e.g., overheating at the top and insufficient cooling at the bottom). This forces a reduction in the testing area to prevent temperature control failure, significantly limiting the testing capacity of a single cabinet. Second, the reliance on only a few ventilation holes at the top or bottom results in a low effective ventilation area and limited heat dissipation rate, necessitating longer heating / cooling times and significantly increasing energy consumption. Third, the dense stacking of test samples on shelves means heat is conducted only vertically, lacking horizontal heat diffusion paths, exacerbating the risk of localized high temperatures and forcing a reduction in single-layer load density. Fourth, the shelves are often sealed, airtight welded structures, hindering airflow and creating a vicious cycle. Therefore, existing aging cabinets also suffer from problems such as the inability to achieve stratified hot air flow, small internal ventilation area, and a single heat conduction path, resulting in limited testing capacity and higher energy consumption, requiring further improvements.

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.

[0026] The following is combined with Figures 1-9 A detailed description of the portable power bank aging cabinet of this utility model is provided below:

[0027] A power bank aging cabinet includes a cabinet body 1. An internal partition 12 divides the interior of the cabinet body 1 into a first receiving cavity and a second receiving cavity. The surface of the partition 12 has several vents 13, which are equidistantly arranged. The top of the cabinet body 1 has several air inlets 7, which are symmetrically arranged. The air inlets 7 communicate with the second receiving cavity. The first receiving cavity is connected to the second receiving cavity via the vents 13. The cabinet 1 has several air vents 14 at its bottom, which are symmetrically arranged. The second receiving cavity is connected to the air vents 14. The cabinet 1 has several circular heat dissipation vents 5 on both sides, which are symmetrically arranged. The first receiving cavity is connected to the heat dissipation vents 5. The cabinet 1 has several heat dissipation holes 11 at one end, which are equidistantly arranged. The second receiving cavity is connected to the heat dissipation holes 11.

[0028] The top of the cabinet 1 is provided with a fixing box 8 for installing heating elements. The bottom of the fixing box 8 is connected to the second receiving cavity. The second receiving cavity is provided with several horizontal beams 10, which are evenly spaced from each other. The two ends of each beam 10 are connected to the inner wall of the cabinet 1. The inner wall of the cabinet 1 is provided with several reinforcing strips 9, which extend along the height of the cabinet 1 and form a cross structure between adjacent reinforcing strips 9. The first receiving cavity is provided with several horizontal placement platforms 2, which are evenly spaced from each other. Each placement platform 2 includes a fixing plate 201 and a side plate 202, which are welded together. One end of the fixing plate 201 is bent outward to form a fixing part 208, which extends along the length of the fixing plate 201. The bottom of the fixing plate 201 is provided with a bottom plate 206. Both ends of the base plate 206 are connected to the side plate 202. One end of the side plate 202 is bent outward to form a connecting part 205, which is connected to the inner wall of the cabinet 1. A load-bearing plate 204 is provided at the bottom of the fixing plate 201, and the load-bearing plate 204 is connected to the side plate 202. A fixing rod 207 is provided at the bottom of the fixing plate 201. One end of the fixing rod 207 is connected to the base plate 206, and the other end of the fixing rod 207 is connected to the side plate 202.

The direct conduction design of the second receiving cavity allows the heating module to heat the inside of the cabinet 1 directly, reducing the heat conduction path, improving heat utilization, and reducing energy consumption costs. The equidistant beams 10 of the second receiving cavity form a grid support system, which, together with the cross-shaped reinforcing strips 9 on the inner wall, improves the deformation resistance of the cabinet 1 and adapts to long-term stable operation in high-temperature environments. The reinforcing strips 9, as a stress dispersion structure, effectively prevent the cabinet 1 from cracking due to thermal expansion and contraction.
