Embodiment 1

[0049] refer to image 3 , In the case of no fire, the normal temperature fire fighting water enters the water tank through the inlet, the cooling cycle unit runs at idle speed, the liquid refrigerant in the evaporator 2 absorbs the heat of the normal temperature fire fighting water in the water tank and starts to evaporate, and finally the liquid refrigerant and water are mixed. After the temperature difference is formed between the two, the liquid refrigerant is completely evaporated into a gaseous state, and is sucked by the compressor 4 and compressed into the condenser 3 (air cooling). Under the action of the cooling fan 6, the gaseous refrigerant condenses into a liquid state again. The high-pressure and normal-temperature liquid refrigerant is throttled through the expansion valve 5 and then becomes a low-temperature and low-pressure refrigerant, which enters the evaporator 2 again, evaporates and absorbs heat, completes the refrigerant circulation process, and achieves ...

Embodiment 2

[0051] refer to image 3 , in the case of needing to deal with fire, the mobile intelligent cooling fire-fighting water fire extinguishing device of the present invention can realize rapid movement in a short distance, first open the water pump 9 to output the cooled water stored when there is no fire for emergency fire-fighting and cooling . At the same time, the normal temperature fire fighting water is introduced into the water tank 1. At this time, the cooling cycle unit operates at a high speed, and the liquid refrigerant in the evaporator 2 absorbs the heat of the normal temperature fire fighting water in the water tank and begins to evaporate. After the temperature difference is formed, the liquid refrigerant is completely evaporated into a gaseous state, and is sucked by the compressor 4 and compressed into the condenser 3 (air cooling). , the high-pressure and normal-temperature liquid refrigerant is throttled through the expansion valve 5 and then becomes the low-te...

Abstract

The invention discloses a cooling fire-fighting water fire extinguishing device, a using method thereof and a battery fire extinguishing method, the device comprises a cooling circulation unit, the cooling circulation unit comprises a water tank, an evaporator, a condenser, a compressor, an expansion valve and a heat dissipation fan, the evaporator is placed in the water tank, and the condenser, the compressor and the expansion valve are connected in series between an outlet and an inlet of the evaporator; the heat dissipation fan dissipates heat for the condenser; the fire-fighting water circulating unit comprises a fire-fighting water inlet pipe, a water pump and a fire-fighting water outlet pipe, the fire-fighting water inlet pipe and the fire-fighting water outlet pipe are both communicated with the water tank, and the water pump is arranged on the fire-fighting water outlet pipe. The control unit, the water pump and the compressor are all electrically connected with the control unit, the control unit has two working modes, idling cooling is conducted and low-temperature fire fighting water is stored in the non-fire-behavior handling mode, and high-speed cooling is conducted and the low-temperature fire fighting water is rapidly output in the fire behavior handling mode. The ice water can be stored, and the device is suitable for fire extinguishing in new energy automobile charging parking areas, energy storage power stations and related scenes.

Description

technical field [0001] The present application relates to the technical field of battery fire fighting, and in particular, to a cooling fire water fire extinguishing device and a method for using the same, and a battery fire extinguishing method. Background technique [0002] Different from conventional fire accidents, battery fires, as a special chemical fire, have internal combustion conditions to maintain, and cannot be put out simply by cutting off the three elements of the fire. Even if the open fire is extinguished, the battery is very likely to reignite. . Therefore, the key to dealing with battery fires is to take into account both fire fighting and continuous cooling, so as to avoid greater economic losses and casualties. At present, battery fire extinguishing technologies mainly include four categories of gaseous extinguishing agents (carbon dioxide, heptafluoropropane, perfluorohexanone), dry powder extinguishing agent (ABC extinguishing agent), foam extinguishin...
