Description

Supercooling Tank Control System for Fire Extinguishing Drug Storage The present invention aims to rapidly suppress fires in electric vehicles and electric motorcycles by storing a secondary battery fire extinguishing agent in a sub-zero ultra-low temperature tank. There are two main methods for suppressing secondary battery fires: the first is a suffocation method that cuts off oxygen, and the second is a cooling method that suppresses the fire by rapidly cooling the point of ignition. For example, it can be seen that if a liquid fire extinguishing agent is stored at -20°C or lower and sprayed at the point of ignition, its extinguishing ability becomes several times more powerful than that of a fire extinguishing agent stored at above-freezing temperatures. To achieve this, the purpose of this patented technology is to devise a supercooling tank that stores the fire extinguishing agent using the principle of supercooling, which prevents freezing even below the freezing point. Supercooling refers to a phenomenon in which a molten body, liquid, or solid does not undergo a change even when cooled to a temperature below the phase transition temperature at equilibrium. Each substance has a stable state corresponding to the temperature at that time, so if the temperature is gradually changed, the constituent atoms of the substance can follow the change in temperature while maintaining a stable state at each temperature. However, if the temperature changes suddenly, there is no reason for the constituent atoms to change to a stable state corresponding to each temperature; therefore, a phenomenon occurs where they either retain the stable state at the starting temperature or partially stop changing to a state at the ending temperature. For example, when water is cooled under supercooling conditions, it does not solidify even when the temperature drops below -6 to -7°C. By developing a supercooling storage device utilizing this non-freezing supercooling principle of water, it is possible to use liquid fire extinguishing agents at ultra-low sub-zero temperatures without freezing the liquid fire extinguishing agent even below its freezing point.
