Description

Technical Field

[0001] The utility model relates to a voltage equalizer with a protection structure, belonging to the technical field of voltage equalizers. Background Art

[0002] A voltage equalizer is a device used to maintain voltage balance between multiple battery or capacitor cells connected in series. In energy storage systems, such as those comprised of lithium-ion batteries or supercapacitors, the voltages of individual cells or capacitors can gradually become unbalanced due to factors such as production tolerances, aging, and temperature variations. The voltage equalizer's function is to adjust the charge distribution between these cells to extend the life of the entire system, improve energy efficiency, and ensure safe and stable operation.

[0003] A Chinese patent publication (publication number: CN 219340245 U) discloses an equalizer with a protective structure, including an equalizer body, a protective seat provided at the bottom of the equalizer body, a mounting frame connected to the upper end of the protective seat, the mounting frame being sleeved on the outside of the equalizer body, and a hinge connected to each of the two sides and the rear end of the protective seat, and the two sides and the rear end of the protective seat being connected to the side panels and the back panel via the hinges. By providing a protective seat at the bottom of the equalizer body, a mounting frame provided at the upper end of the protective seat, a cover plate connected to the upper end of the mounting frame, and a foldable cover plate installed above the equalizer body, the sliding keys on the equalizer body are protected, which not only facilitates the fixing of the position of the keys on the equalizer body, prevents accidental contact, but also avoids reaction disorders caused by squeezing of other devices. The bottom of the protective seat is recessed and has ventilation holes, which facilitates the lifting of the bottom surface of the equalizer body from the operating table, facilitates ventilation and heat dissipation of the bottom of the equalizer body, and facilitates the use of the equalizer body.

The high temperature that lasts for a long time will greatly reduce the service life of the internal parts of the equalizer. However, the existing equalizer can only dissipate heat through external air circulation, and the heat dissipation efficiency is low.

[0005] Therefore, a voltage equalizer with a protection structure is proposed. Utility Model Content
