Title:
INTEGRATED STRUCTURE FOR DELAYING THERMAL RUNAWAY
Document Type and Number:
WIPO Patent Application WO/2022/135098
Kind Code:
A1
Abstract:
Disclosed in the present application is an integrated structure for delaying thermal runaway, comprising a liquid cooling plate, a plurality of energy units and a protective plate; a liquid cooling cavity is defined in the liquid cooling plate; a cooling liquid comprising a fire extinguishing agent is disposed in the liquid cooling cavity, and a placement groove is formed in the middle of the liquid cooling plate; the plurality of energy units are spaced out and are adhered in the placement groove side by side, every two adjacent energy units are arranged face to face, and each energy unit is provided with an explosion-proof valve; the explosion-proof valves are arranged directly opposite to the liquid cooling plate, and the explosion-proof valves can break the liquid cooling plate when each energy unit undergoes thermal runaway so as to enable the cooling liquid to flow out; the protective plate is disposed at the top end of the plurality of energy units, and the protective plate is provided with a plurality of grids; every two adjacent grids form a partition groove, and one end of each energy unit can extend into one partition groove.
