[0019] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model.

[0020] Please refer to Figures 1-4 The utility model provides a kind of technical scheme: a new energy battery fire extinguishing cooling device, including shell 1, two inner shells 4 are symmetrically installed in the inside of shell 1, shell 5 is installed between the two inner shells 4, and the two sides of shell 5 are communicated with exhaust pipe 6;

[0021] The side of shell 5 is communicated with air inlet pipe 3, and check valve 11 is installed at the end of air inlet pipe 3, installation cylinder 9 is installed on the other side of shell 5, compressed gas cylinder 7 is installed on installation cylinder 9, and electronic valve 10 for controlling the exhaust of compressed gas cylinder 7 is installed at one end of installation cylinder 9.

[0022] As shown in Figure 3 And Figure 4 : exhaust pipe 6 is evenly provided with exhaust hole 8; through the above setting, gas can be discharged into the inside of inner shell 4 through exhaust hole 8, to further carry out the cooling work to battery pack, to avoid the emergence of the case that temperature is too high.

[0023] As shown in Figure 2 And Figure 3 : a plurality of battery packs are evenly installed in the inside of inner shell 4.

[0024] like Figure 1 As shown: A cover 2 is installed on the top of the outer casing 1; through the above settings, the casing 5 can be sealed to protect and fix the equipment.

[0025] like Figure 2 As shown: The compressed gas cylinder 7 uses an inert gas; through the above settings, inert gases, such as carbon dioxide, nitrogen, argon or mixtures thereof, are used to reduce the oxygen concentration in the fire scene, thereby achieving the purpose of extinguishing the fire.

[0026] like Figure 2 As shown: A temperature sensor for detecting temperature is installed inside the inner shell 4; with the above settings, when the temperature is too high, the temperature sensor sends information to the controller, and then the controller controls the electronic valve 10 to open, thereby allowing the gas inside the compressed gas cylinder 7 to be discharged into the exhaust pipe 6.

[0027] Working principle: During normal use, the air inlet pipe 3 is connected to the air pump or external air passage. Air enters the interior of the housing 5 through the one-way valve 11 and then is discharged into the interior of the exhaust pipe 6. The exhaust port 8 is used to cool down the internal battery pack and prevent the battery pack from overheating.

[0028] At the same time, the internal temperature is detected by a temperature sensor. When the temperature is too high and a fire occurs, the temperature sensor sends the detected signal to the controller. Then the controller controls the electronic valve 10 to open, so that the inert gas inside the compressed gas cylinder 7 can enter the interior through the exhaust pipe 6 and the exhaust port 8, which facilitates fire extinguishing.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
