Technical Field

The invention relates to the technical field of fire fighting, in particular to a novel energy storage container fire fighting system.

Background

With the popularization and application of new energy sources such as solar energy, wind energy and the like, an energy storage technology develops, and lithium batteries gradually become mainstream products for energy storage because of the advantages of higher energy, long service life, high rated voltage, high power bearing capacity, very low self-discharge rate, light weight, environmental protection, basically no water consumption in production and the like.

Under normal conditions, fire protection systems are arranged in the energy storage container, and sensors are arranged to perform early warning and triggering; the traditional fire-fighting design is that fire is directly put out from the outside of an electric box through a pipe network; however, the conventional method has the following disadvantages: the fire can not be extinguished in a large fire, and the risk of reburning exists after the fire is extinguished.

Disclosure of Invention

The invention provides a novel energy storage container fire-fighting system which can provide a fire-fighting function for an energy storage battery cell in an energy storage container.

The invention adopts the following technical scheme.

A novel energy storage container fire-fighting system is used for providing a fire-fighting function for an electric box used as electric storage equipment in a container, an electric storage module is formed by a plurality of electric cores in the electric box, and the fire-fighting system comprises a water cooling pipeline arranged in the electric box; a water-cooling pipeline at the bottom of the electric box forms a first heat dissipation structure for dissipating heat of the side part of the electric core; a water cooling pipeline between the electric cores in the electric box is vertically arranged to form a second heat dissipation structure for dissipating heat of the top surface of the electric core; when the battery core is out of control due to heat, the high temperature generated by the battery core escapes from the top surface of the battery core and melts the pipe wall of the water cooling pipeline in the second heat dissipation structure, so that the water in the water cooling pipeline flows out and submerges the battery core to perform the fire-fighting function.

The battery cell is horizontally and transversely arranged in the electric box; the top surface of the battery cell faces the side surface of the electric box.

And an explosion-proof valve is arranged on the top surface of the battery cell, and when the battery cell is out of control due to heat, the explosion-proof valve is opened, so that high temperature generated by the out-of-control battery cell escapes and is contacted with a water cooling pipeline in the second heat dissipation structure.

And heat-conducting media are arranged between the first heat-radiating structure and the side surface part of the battery core and between the second heat-radiating structure and the top surface part of the battery core.

After the water cooling pipeline in the second heat dissipation structure penetrates through the position where the battery core is located, a third heat dissipation structure for dissipating heat of the busbar is formed at the busbar position of the power storage equipment; the third heat dissipation structure is connected with the busbar through a heat conducting medium so as to dissipate heat of the busbar.

The first heat dissipation structure is a water cooling plate at the bottom of the electric box.

And the water cooling pipeline in the second heat dissipation structure is made and molded by a material which can be melted by the thermal runaway temperature of the battery core.

According to the scheme provided by the invention, the electric box core can be completely immersed when the fire-fighting function is exerted, so that a larger fire can be effectively extinguished, and the risk of reburning is reduced.

Compared with the traditional mode, the traditional water-cooling heat dissipation structure adopts a water-cooling plate placed at the bottom of the battery cell for heat dissipation, but the heat dissipation effect is poor due to the small area ratio of the bottom of the battery cell, and the service life of the battery cell is influenced; the scheme of the invention can simultaneously realize the heat dissipation function and the fire fighting function, has compact structure, starts the fire fighting function in a pipe wall melting mode and has high reliability.
