Abstract

The invention provides a battery pack cooling system. The battery pack cooling system of the present invention includes: a casing, an air duct, a fan, and at least two air outlets; the casing includes an upper cover and a box body, and the upper cover is connected to the box body; the air duct is arranged on the box body, and the air duct includes an airflow cavity , the air passage and the air outlet; the air flow chamber is arranged at the bottom of the box; the air passage is arranged on the side wall of the box, and the bottom of the air passage is connected with the air flow chamber; the air outlet is arranged on the shell and It communicates with the air passage, wherein at least one air outlet is arranged on the upper cover and corresponds to the top of the air passage; the fan is arranged in the air passage. The invention realizes the effect of improving the battery pack to accelerate heat dissipation in the battery pack in an environment with poor natural wind flow, so that the components in the battery pack can work in a stable temperature range and improve the service life of the battery pack.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a battery pack cooling system. Background technique [0002] At present, with the rapid development of the new energy industry, batteries are used in a wider range of fields, such as in electric vehicles. By using the power battery system to provide electric energy for electric vehicles, the vehicles can run. [0003] Generally, the battery will generate a certain amount of heat no matter it is in the charging state or the discharging state. When the heat is too high, the battery temperature will exceed the normal temperature range value, thus the battery performance will decrease and the cycle life will be reduced. In this way, we need to cool the power battery system to make it reach an optimal state. [0004] The battery pack cooling system in the related art mostly uses air cooling or water cooling to cool the battery. When air cooling is used for cooling, natural wind is ...
