锂离子电池组翅片-空气协同冷却的数值模拟

摘要

热管理是维护锂离子电池组安全运行、延长电池组使用寿命的重要手段。为有效抑制电池组在大倍率放电过程中的温升，提出了翅片-空气协同冷却新方法，并采用数值模拟对其控温效果进行了分析。结果表明，与传统空冷方法相比，翅片-空气协同冷却法能有效抑制电池的温升，并大幅度减小空冷散热的能量损耗。对翅片强化传热机理的分析表明，翅片的导热能力是决定翅片-空气协同冷却效果的关键因素。

Abstract：

Thermal management is important to ensure the safe operation and prolong life-span of a lithium-ion battery pack. In order to realize efficient thermal management of lithium-ion battery pack, a novel cooling method coupling metal fins and air flow is proposed. A three-dimensional-dynamic model is used to simulate the temperature profile in a lithium-ion battery. It is shown that the coupling of metal fins and air flow is much more superior to common air cooling in terms of controlling the maximum temperature of the battery and decreasing the energy consumption. The mechanism of cooling enhancement by fins is discussed. The thermal conductivity of the fins proves to be a critical factor which determines the cooling effect.

Keywords： lithium-ion battery； couple metal fins and air flow； temperature control； numerical simulation
