Abstract

A cooling and flame-isolating appts. for extinguishing fire by aerosol features that the chemicals are used for cooling because the chemicals are decomposed at different temps to absorb heat. It is a 4-layer structure in which the first and the fourth layers are used for isolating flame, and the second and the third layers for cooling purpose.

Description

technical field

[0001] The invention relates to an aerosol cooling and flame blocking device, which is suitable for the occasion of cooling down and blocking flame with fire extinguishing aerosol. Background technique

[0002] The existing aerosol cooling and temperature blocking flame devices are based on two main principles: one is a physical method, which is mainly to extend the transmission channel of the aerosol, and use materials with good heat transfer properties to dissipate heat to reduce the temperature. The second is the chemical method, which mainly adopts two methods. One is to dope materials in the aerosol generating agent to reduce the initial temperature of the aerosol; The temperature is lowered.

[0003] The disadvantage of the above-mentioned cooling technology is that the physical method will increase the volume and weight of the fire extinguishing aerosol generating device. The existing chemical methods either reduce the aerosol production efficiency or...
