Abstract

The invention provides an air-cooled battery pack with high heat dissipation efficiency. A second side plate can be moved along a first mounting plate so that the opening and plugging of a first heat emission hole on the first side plate are realized. A second sealing plate can be moved along a second mounting plate so that the opening and plugging of a second heat emission hole on the second sealing plate are realized. The air-cooled battery pack ensures the heat dissipation of the battery pack and the tightness of the battery pack. Through arrangement of fans along four directions of a cell, cross-ventilation is improved and fast heat dissipation is realized. Multiple cell support units are flexibly connected. Pressure relief sheets are arranged. The pressure relief sheets between each two adjacent cell support units are arranged at an interval. In cell explosion, heat and pressure can be effectively released, the explosion-caused surrounding cell loss is reduced, the safety coefficients of the module, assembly and whole battery pack are improved, a battery pack maintenance cost is reduced, a contact area with the air is increased and a part of heat produced by cell work is released.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to an air-cooled battery pack with high heat dissipation efficiency. Background technique [0002] A module is composed of multiple single batteries or super capacitors connected in series and parallel, and then a battery pack with a certain voltage and capacity is formed by connecting multiple modules in series and parallel, and placed inside a sealed box to form a battery pack. During the use of the battery pack, a large amount of heat will be generated, causing the temperature of the battery pack to rise. Especially in summer, the battery pack is prone to high-temperature fire, explosion and other safety hazards. Battery pack heat dissipation technology is a big problem. Battery pack sealing requirements for safety considerations and battery pack heat dissipation are relatively contradictory issues. Most battery packs use air-cooled heat dissipation and liquid-cooled heat dissi...
