Novel energy storage container fire extinguishing system

Abstract

The invention provides a novel energy storage container fire extinguishing system which is used for providing a fire extinguishing function for an electricity box used as electricity storage equipment in a container. An electricity storage module is formed by a plurality of battery cells in the electricity box, and the fire extinguishing system comprises a water cooling pipeline arranged in the electricity box. The water cooling pipeline at the bottom of the electricity box forms a first heat dissipation structure for dissipating heat of the side surface part of the battery cells. The portion, between the battery cells in the electricity box, of the water cooling pipeline is vertically arranged to form a second heat dissipation structure for dissipating heat of the top surface parts of the battery cells. When the battery cells are in thermal runaway, high temperature generated by the battery cells escapes from the top surfaces of the battery cells and melts the pipe wall of the wate cooling pipeline in the second heat dissipation structure, so that water in the water cooling pipeline flows out and immerses the battery cells to execute the fire-fighting function. According to the system, the fire-fighting function can be provided for the energy storage battery cells in the energy storage container.

Description

technical field [0001] The invention relates to the technical field of fire protection, in particular to a novel energy storage container fire protection system. Background technique [0002] With the promotion and application of new energy sources such as solar energy and wind energy, energy storage technology has also developed. Lithium batteries have high energy, long service life, high rated voltage, high power tolerance, low self-discharge rate, and light weight. , green and environmental protection, and basically no water consumption in production, it has gradually become the mainstream product of energy storage. [0003] Under normal circumstances, a fire-fighting system is arranged inside the energy storage container, and sensors are usually arranged for early warning and triggering; the traditional fire-fighting design uses the pipe network to directly extinguish the fire from the outside of the electrical box; however, the traditional method has the following disad...
