Embodiment 1

[0044] see Figure 1-Figure 2 In this embodiment, a heat pipe with a gas generating device for a battery includes a heat pipe body 1, the heat-conducting working medium in the heat pipe body 1 is a fire-fighting heat-conducting medium, and a gas generating device 3 is arranged in the hollow structure 2 of the heat pipe body 1, The hollow structure 2 of the heat pipe body 1 is a steam flow cavity, that is, what flows in the hollow structure 2 of the heat pipe body 1 is the vaporized steam of the fire-fighting heat transfer medium.

[0045] The gas generating device 3 of this embodiment includes a package casing, a temperature-sensitive initiator 31 and a gas generating agent 32. The package casing has a hexagonal structure and is a metal casing. The metal casing is compatible with fire-fighting and heat-conducting media. Capacitance means that there is no chemical reaction between the metal shell and the fire-fighting heat-conducting medium; the encapsulating shell is placed in...

Embodiment 2

[0054] see Figure 3-Figure 4 In this embodiment, a heat pipe with a gas generating device for a battery includes a heat pipe body 1, the heat-conducting working medium in the heat pipe body 1 is a fire-fighting heat-conducting medium, and a gas generating device 3 is arranged in the hollow structure 2 of the heat pipe body 1, The hollow structure 2 of the heat pipe body 1 is a steam flow cavity, that is, what flows in the hollow structure 2 of the heat pipe body 1 is the vaporized steam of the fire-fighting heat transfer medium.

[0055] The gas generating device 3 of the present embodiment includes a packaging casing, a temperature-sensitive initiator 31 and a gas generating agent 32. The packaging casing has a hexagonal structure and is a plastic casing. The plastic casing is compatible with fire-fighting and heat-conducting media. Capacitance means that there is no chemical reaction between the metal shell and the fire-fighting heat-conducting medium; the encapsulating she...

Embodiment 3

[0064] see Figure 5-Figure 6 In this embodiment, a heat pipe with a gas generating device for a battery includes a heat pipe body 1, the heat-conducting working medium in the heat pipe body 1 is a fire-fighting heat-conducting medium, and a gas generating device 3 is arranged in the hollow structure 2 of the heat pipe body 1, The hollow structure 2 of the heat pipe body 1 is a steam flow cavity, that is, what flows in the hollow structure 2 of the heat pipe body 1 is the vaporized steam of the fire-fighting heat transfer medium.

[0065] The gas generating device 3 of the present embodiment includes a package casing, a temperature-sensitive initiator 31 and a gas generating agent 32. The package casing is a hexagonal structure, and it is a copper casing. The copper casing is compatible with the fire-fighting and heat-conducting medium Capacitance means that there is no chemical reaction between the metal shell and the fire-fighting heat-conducting medium; the encapsulating sh...

Abstract

The invention provides a heat pipe used for a battery and containing a gas production device and a fire extinguishing method of the heat pipe, and belongs to the technical field of energy storage batteries. The heat pipe comprises a heat pipe body, a heat conduction working medium in the heat pipe body is a fire-fighting heat conduction medium, and the gas production device is arranged in a hollow structure of the heat pipe body. The gas production device of the heat pipe used for the battery and containing the gas production device is simple in structure, and has no influence on the structure of the battery itself and the structure of the heat pipe itself, namely, the original structure and size of the battery are not influenced.

Description

technical field [0001] The invention belongs to the technical field of energy storage batteries, and relates to the safety technology of energy storage batteries, in particular to a heat pipe with a gas generating device for batteries and a fire extinguishing method thereof. Background technique [0002] In recent years, lithium battery technology has developed rapidly, and lithium batteries have been applied to more and more fields. Lithium batteries will generate heat during operation. If the heat generated during repeated use is too large, the heat cannot be effectively dissipated, which will affect the stability of lithium batteries and shorten the service life of lithium batteries. When the temperature If it rises further, the lithium battery will go out of control, and the electrolyte inside will decompose to produce flammable gas. If the flammable gas continues to accumulate, there will be a risk of explosion and fire. Therefore, the safety of lithium batteries has a...
