In 31 overflow of air port to each battery case 3, so that the open fire in battery case 3 be put out；Then pass through 8 He of flow of media pipeline again
Re-ignition inhibitor is injected into cabinet body 1 by fire main 2, and re-ignition inhibitor passes through 31 overflow of the first air outlet to each electricity
In pond case 3, and submerge whole cabinet, thus make battery 5 can not re-ignition, be divided between extinguishing chemical and the injection length of re-ignition inhibitor
10-300 seconds；Meanwhile when being passed through extinguishing chemical and re-ignition inhibitor, by the first air inlet 11 and air outlet mechanism 12 in machine
The air-flow flowed in cabinet ontology 1 can also give extinguishing chemical and the certain flowing power-assisted and guiding of re-ignition inhibitor, to accelerate to go out
Fire and the process for inhibiting re-ignition.
In above-described embodiment, snakelike air duct is formed between each battery case 3, it is most lower from being located at after air-flow enters exhaust air flue
The battery case 3 of side starts, and with snakelike flow path followed by each battery case 3, finally flows out from air outlet mechanism 12, from
And it radiates to the greatest extent to battery case 3.When it is implemented, the bottom of each battery case 3 opens up referring to Fig. 6 and Fig. 7
There is the second air inlet 32, in two battery cases 3 of arbitrary neighborhood, second air inlet 32 of the air-flow from underlying battery case 3
Into and from underlying battery case 3 the outflow of the first air outlet 31, then again from the second of the battery case 3 being located above into
Air port 32 enters and flows out from the first air outlet 31 of the battery case 3 being located above, to form snakelike air duct.Each battery case
3 the first air outlet 31 can be one, and the first air outlet 31 can be opened in the side of the same side of each battery case 3, can also
To be opened in the not ipsilateral side of each battery case 3, material is thus formed a snakelike air ducts, alternatively, referring to Fig. 8, Mei Ge electricity
The opposite two sides of pond case 3 offer the first air outlet 31, thus respectively form a snake in the two sides of the battery of permutation 5
Shape air duct.Specifically, referring to Fig. 9, accommodate multiple row battery 5 in battery case 3, the first air outlet 31 along a column battery 5 row
Column direction opens up, and length is slightly less than the length of a column battery 5.
Referring to Figure 10, in above-described embodiment, the second air inlet 32 is multiple, and each second air inlet 32 is along a column battery
5 orientation successively opens up, when it is implemented, the second air inlet 32 is waist-shaped hole.At least two column electricity are accommodated in battery case 3
Pond 5, has gap 6 between two adjacent column batteries 5, and the second air inlet 32 is located at the bottom of battery case 3 and corresponding to gap 6
Place, in order to which air-flow enters in battery case 3.
Referring again to Fig. 6 and Fig. 7, further includes: multiple support plates 7, each support plate 7 are connected with the inner wall of cabinet body 1
It connects, and is provided with support plate 7 between two battery cases 3 of arbitrary neighborhood, support plate 7 can be to the battery case 3 being positioned above
Play certain supporting role.Each support plate 7 offers ventilation opening 71, institute on the battery case 3 that ventilation opening 71 is positioned above
The second air inlet 32 opened up is corresponding, to guarantee that air-flow can smoothly enter into battery case 3.When it is implemented, ventilation opening 71 and
Two air inlets 32 can correspond, can also be with corresponding several each second air inlets 32 of a ventilation opening 71.It should be noted that
The setting of second air inlet 32, the first air outlet 31 and ventilation opening 71, together forms snakelike air duct.
Referring again to Fig. 3 and Fig. 6, air outlet mechanism 12 includes: the second air outlet (not shown) and blower 121, wherein
Second air outlet is opened in the top of cabinet body 1, and blower 121 is then set at the second air outlet, to guide in cabinet body 1
Air-flow discharge.When it is implemented, blower 121 is located at the outside of cabinet body 1.Air outlet mechanism 12 further include: guide duct 122,
Guide duct 122 is arranged on blower 121, and the location bending where guide duct 122 to separate first air inlet 11, thus will row
The air-flow of higher temperature out is directed to the direction far from the first air inlet 11, guarantees the air-flow flowed into from the first air inlet 11
Temperature is lower, to preferably be cooled down to battery case 3.
In above-described embodiment, the top of partition 4 extends to the outside of cabinet body 1, and by the first air inlet 11 and outlet air
Mechanism 12 separates, to further prevent the high temperature gas flow of discharge to impact the temperature of the air-flow near the first air inlet 11,
Guarantee air-flow to the cooling effect of battery case 3.
To sum up, in the present embodiment, air-flow enters cabinet body 1 under the action of air outlet mechanism 12, from the first air inlet 11
It is interior, and each battery case 3 is flowed through from bottom to up, it is finally flowed out from air outlet mechanism 12, to be cooled down to battery 5, to maintain
The safe operation of battery 5；Meanwhile when thermal runaway occurs for battery 5, first passing through flow of media pipeline 8 and fire main 2 will put out a fire
Agent is injected into cabinet body 1, and extinguishing chemical passes through in 31 overflow of the first air outlet to each battery case 3, thus by battery case 3
Open fire put out；Then re-ignition inhibitor is injected into cabinet body 1 by flow of media pipeline 8 and fire main 2 again, it is multiple
It fires inhibitor to pass through in 31 overflow of the first air outlet to each battery case 3, and submerges whole cabinet, to make battery 5 that can not answer
Combustion；Meanwhile snakelike air duct is formed between each battery case 3, after air-flow enters exhaust air flue, opened from the battery case 3 for being located at bottom
Begin, with snakelike flow path followed by each battery case 3, is finally flowed out from air outlet mechanism 12, thus to the greatest extent
It radiates to battery case 3.The setting of second air inlet 32, the first air outlet 31 and ventilation opening 71, together forms snakelike wind
Road has carried out preferable heat dissipation to battery case 5；Also, battery case 5 and cabinet body 1 are tightly connected, and can store re-ignition inhibition
Agent, to be effectively prevented 5 re-ignition of battery.
