Abstract

The invention discloses a power battery cooling device based on the ion wind principle, which comprises an ion wind heat dissipation module, a heat dissipation base, a heat dissipation metal fin module and a power battery module. The main body of the ion wind heat dissipation module is the ion wind generator, the heat dissipation base is designed in the shape of a mesh, the heat dissipation metal fin module is a hollow cuboid heat dissipation metal frame, and the phase change material is stored inside, and the power battery module is placed behind the heat dissipation metal frame , located above the cooling base. When the power battery module generates a large amount of heat, it reaches the temperature required for the phase change of the material, and the phase change absorbs a large amount of heat. At the same time, the ion wind cooling module generates ion wind, which heats the heat dissipation base, power battery module and heat dissipation metal fin module. Heat dissipation. The invention can realize high-efficiency cooling of the power battery under the working conditions of high discharge rate and high working temperature, improve the working reliability of the power battery, and prolong the service life of the power battery.

Description

technical field [0001] The invention relates to a power battery cooling device, in particular to a power battery cooling method and device based on the ion wind principle, and belongs to the technical field of power battery thermal management. Background technique [0002] As a power battery, lithium batteries have the advantages of high specific energy, high specific power, long service life, and wide operating range, and have been widely used in electric vehicles and hybrid electric vehicles. While power batteries are widely used, their safety issues are gradually exposed. Because lithium batteries generate a lot of heat during high-rate charging and discharging, if the heat is not dissipated in time, it will lead to overheating of the battery, which will affect the service life of the battery, and even lead to safety accidents. Therefore, efficient thermal management of power batteries has become an effective method to solve heat dissipation problems. [0003] Most of t...
