AI Technical Summary
Existing portable aerosol fire extinguishing devices generate high temperatures during the vaporization and spraying process, posing a risk of burns and making it difficult to effectively cool them down.
A heat-insulated fire extinguishing device was designed, comprising an agent chamber and a heat-insulating chamber inside the shell. When the fire extinguishing components are heated, they vaporize to generate aerosols and are sprayed through the heat-insulating chamber to cool down. The device utilizes the spray channel formed by the heat-insulating plate for flow cooling.
This achieves a temperature reduction when the aerosol is sprayed, avoiding the safety hazard of burns and improving fire extinguishing efficiency and cooling effect.
