Power battery pack with radiator for electric vehicle

Abstract

The invention discloses a power battery pack with a radiator for an electric vehicle. The power battery pack comprises a power battery case. A plurality of single batteries are arranged in the battery case. A high-heat capacity material is filled into gaps between every two single batteries. A plurality of pulsating heat pipes are inserted into the high-heat capacity material. The evaporation end of the pulsating heat pipe is in contact with the high-heat capacity material, the condensation end of the pulsating heat pipe is in contact with the external environment of the battery pack, and an insulating end between the evaporation end and the condensation end isolates the internal and external thermal environments of the battery pack by a heat insulation case cover to avoid the heat of a condensation section flowing back. The power battery pack can rotate within the range of 360 degrees without influencing radiation, has a simple and compact structure and vast application prospect, is not required to additionally consume the electric energy of the power batteries, and can meet the highly-efficient radiation of the power batteries of the electric vehicle.

Description

technical field [0001] The invention relates to electric vehicle power battery technology, in particular to an electric vehicle power battery pack with a cooling device. Background technique [0002] Due to the increasingly prominent problems of energy shortage and environmental pollution, electric vehicles have gradually attracted attention because they can save energy and reduce the emission of greenhouse gases and harmful pollutants such as dust. However, during the charging and discharging process of the power battery, the internal chemical reaction is complex, especially during the charging and discharging process of large size and high current, a large amount of heat is rapidly generated inside the battery, and the accumulation of heat will inevitably cause the temperature of the battery to rise, resulting in a decline in battery performance. There may even be phenomena such as liquid leakage, outgassing, and smoke. In severe cases, the battery will burn violently and ...

AI Technical Summary

Problems solved by technology

[0003] In recent years, the urgent need for heat dissipation of electric vehicle power batteries has attracted the attention of many electric vehicle manufacturers and battery manufacturers. At present, power batteries on the market generally adopt the simplest air cooling method, and the structure is complex, and the heat dissipation effect is not ideal.
