Thermal aerosol fire extinguishing device for intelligent battery swapping cabinets.

Thermal aerosol fire extinguishing device for intelligent battery Swap Station cabinets.

At present, the mainstream automatic fire extinguishing systems on the market mainly include water-based fire extinguishing, dry powder automatic fire extinguishing, probe tube temperature sensing self starting fire extinguishing, hot aerosol fire extinguishing, etc.

Water based fire extinguishers can cause damage to electrical equipment when sprayed, and are not suitable for live fires in places such as power exchange cabinets. The storage of water-based fire extinguishing agents also requires high sealing of the equipment. In the case of unattended power exchange cabinets for a long time, consideration should be given to the situation where the box may rupture due to force majeure and the fire extinguishing agent may leak.

After the dry powder fire extinguishing device is activated, the dry powder will completely settle within 1-2 minutes. Therefore, using it in the battery exchange cabinet cannot meet the fire suppression effect on the environment. Moreover, over time, the dry powder will undergo denaturation and moisture, greatly reducing its fire extinguishing ability. In cold northern regions, the environmental temperature in winter is lower than the storage temperature of the dry powder, and being in a low-temperature environment for a long time will also affect the fire extinguishing performance of the dry powder. For safety reasons, dry powder fire extinguishers cannot achieve the expected fire extinguishing effect.

In the long-term use process, the places where the battery exchange cabinet is used are usually unattended outdoors or around large squares, working around the clock in environments such as high temperatures and battery collisions, which are highly prone to causing fires. Fire extinguishing devices need to be installed to protect the battery swapping cabinet from extinguishing flames in the early stages of a fire.

Due to the fact that most cabinets are placed in unattended outdoor areas, the selection of fire extinguishing devices is to be able to provide initial disposal of battery fires inside the cabinets before personnel arrive, ensuring that the fire does not spread or develop.

The battery swapping cabinet has a small space and special environment, and ordinary fire extinguishers cannot extinguish fires in their early stages. At the same time, due to limited space and the inability to install pipelines, nozzles, or fire alarm systems, the automatic fire extinguishing system cannot work properly, resulting in huge economic losses. The use of hot aerosol fire extinguishing devices can effectively solve this problem.
