Description
Technical Field
The utility model relates to a fire-fighting apparatus field particularly, relates to an electric automobile group battery cooling device.
Background
At present, along with electric automobile's production and sales volume is bigger and bigger, the accident that catches fire is more and more, this is because automobile-used the most lithium ion battery that is of new forms of energy, battery safety problem is the focus of people's focus of focusing on first, make monomer electric core temperature rise earlier behind the monomer electric core thermal runaway produce gas, the temperature further risees again, the monomer electric core burning of messenger, will produce the influence to other peripheral monomer electric cores simultaneously, produce chain reaction, finally take place the battery explosion, the new forms of energy car catches fire, cause the serious incident of casualties even. The electric automobile is difficult to extinguish fire after catching fire because the ignition point is a battery out of control, and a battery pack (battery pack) of the electric automobile is basically installed at the position of an automobile chassis, the traditional fire extinguishing gun is difficult to cool the position, the effect of quickly cooling and extinguishing fire cannot be achieved, if a fireman needs to cool and extinguish the fire at the position, the fireman needs to close to and squat beside the automobile for a long time to spray the bottom of the automobile, the danger is extremely high, meanwhile, if the fire of the electric automobile is caused by the fact that the battery pack generates heat and fires, the burning dense smoke is likely to contain toxic substances and can also influence the personal safety of surrounding people and rescuers, so that the fireman can firstly evacuate the surrounding people during actual rescue, the occurrence of a group poisoning event is prevented, the fireman aims at the automobile from the outer side to cool and extinguish the hidden danger, and the fireman can continue to continuously and comprehensively cool the battery pack and the automobile body until the dangerous situation is thoroughly eliminated.
Because the electric vehicle is usually the chassis battery set, it starts burning. The ordinary squirt that the fire fighter was equipped with can't carry out effectual cooling and put out a fire to the group battery, need overturn the electric automobile and invert even, just can carry out more direct cooling operation, has brought very big inconvenience for the rescue personnel, also has certain safety risk simultaneously. The battery pack of current fire-fighting lance can't continuously cool off accident vehicle's battery pack fast effectively, leads to the battery pack to obtain effective cooling, and when electric automobile was in the state of catching fire, the battery pack was heated continuously and is sent out thermal runaway, and the battery pack in case take place thermal runaway, will release a large amount of heat energy in the short time, very easily causes burning and explosion.
In summary, we propose a battery pack cooling device for an electric vehicle to solve the above technical problems.
