微热管阵列应用于锂电池模块的散热实验
Experiment on heat dispersion of lithium-ion battery based on micro heat pipe array
摘要
Abstract
The thermal control and heat management of lithium-ion ( Li-ion) batteries in high-power applications remains a chal-lenge to be addressed before widespread commercialization. To solve the problem, micro heat pipe array ( MHPA) is used to design Li-ion battery packs cooling system. Experiments were conducted utilizing Li-ion battery packs under open conditions with constant current of18A(1C) and36A(2C). The temperatures were measured with and without micro heat pipe arrays during the charge--discharge cycle.At the rates of 1 C and 2 C, the temperature results of the Li-ion battery packs validate the effectiveness of the functional heat con-ducting material-MHPA in lowering the temperature of the battery packs, as well as the temperature difference inside the packs, the temperature and temperature difference could be controlled within 40℃ and 5℃ respectively . Thus, they preliminarily solve the influ-ence of temperature on battery life and capacity. Based on the experimental data, the heat in one of the 2 C working conditions was cal-culated, and the convection heat dissipation by MHPA reached 40% of the heat generation in the pack.关键词
