摘要
烟火型气体发生器已广泛地应用于各种气囊系统和救生装置中,为了吸收气体发生剂燃烧后放出的热量,降低产气温度,需要对燃烧过程产生的气体进行冷却。本文就冷却剂的选择、使用方式、冷却单元结构设计及冷却过程数值模拟进行了综述。
Pyrotechnic gas generator is widely used for various airbag systems and lifesaving equipment. Coolant needs to be appended in the gas generator to absorb heat which was given out by combustion of gas generating agent,thereby it reduces the temperature of gas. In this paper,the choice of physical coolant and chemical coolant for pyrotechnic gas generator,cooling methods,the configuration design of cooling cell and numerical simulation of cooling course are reviewed.
