1. by adopting the pressure bottle with temperature sensing, the fire extinguishing material in the bottle can be released once the temperature is sensed to be too high, and the fire extinguishing material mainly comprises perfluoro-hexyl ketone and alkyl halide, thereby achieving the aim of extinguishing fire.
2. The pressure bottle filled with fire extinguishing materials is adopted for extinguishing fire, a temperature sensing device is arranged at a pressure release valve of the power battery, if the pressure release valve releases pressure, the internal thermal runaway of the power battery is indicated, the fire extinguishing agent in the pressure container is sprayed out, and the area near the pressure release valve is filled to achieve the aim of extinguishing fire.
3. The fire extinguishing agent is additionally arranged in the pipe, the pipe is coiled in the equipment, after the equipment fires, the pipe is burnt, and the fire extinguishing agent in the pipe is sprayed out to achieve the aim of fire extinguishing.
The three fire extinguishing schemes have the following defects:
1. the fire can be extinguished only by sensing the temperature and pressure changes in the later stage of the fire, the fire can not be extinguished in the early stage of the fire, and the fire prevention efficiency is greatly limited.
2. The nozzle of the pressure bottle can not face the fire source, a large amount of fire extinguishing agent can be sprayed out for extinguishing fire at a time, and after the fire extinguishing agent is scattered, the fire is burned again, and at the moment, the fire extinguishing agent does not exist in the pressure tank, so that an important fire extinguishing opportunity is lost.
3. The temperature and pressure sensing elements added in the fire extinguishing scheme have the risk of damage, and the aim of extinguishing fire can not be fulfilled in an emergency closing head.
4. The coil pipe is adopted to extinguish fire, and after the tube is burnt out, all fire extinguishing agents are sprayed out and cannot be used for the second time, and the secondary fire cannot be extinguished.
