高效气溶胶灭火剂（HEAE）是由固体推进剂技术发展而成，属于烟火类药剂。当HEAE灭火剂生成气溶胶，出口气溶胶温度很高，会对被保护空间形成二次危害，影响灭火效果，因此灭火装置喷放时需作降温处理。针对灭火装置的特点，采用外冷却方法，利用固化的化学冷却剂，对高温HEAE燃烧产物实施冷却处理。重点考察了冷却块中冷却剂的含量、冷却块的孔径以及冷却块与HEAE灭火剂重量比对冷却降温效果的影响。结果表明，通过合理调节冷却块中冷却剂的含量、冷却块的孔径以及冷却块与HEAE灭火剂质量比，能有效地降低灭火装置喷口处的气溶胶灭火介质的温度。

Highly effective aerosol fire-extinguishing agent (HEAE) is a safe and practical alternative to Halon which developed from pyrotechnics. When HEAE starts up, it generates aerosol products with high temperature so that its temperature must be lowered to not harmful to person and material. Aerosol products are cooled with exterior cooling by use of chemical coolant. This article mainly discussed the influences of refrigerant contents, apertures, proportion of refrigerant on the spout temperature of HEAE.
