|1. (WO2018137374) BATTERY LIQUID COOLING DEVICE AND BATTERY SYSTEM|
|Applicants:||HEFEI GUOXUAN HIGH-TECH POWER ENERGY CO., LTD.
|Title:||BATTERY LIQUID COOLING DEVICE AND BATTERY SYSTEM|
The present invention relates to a battery liquid cooling device and a battery system. The battery liquid cooling device comprises a liquid cooling plate. One or more through-holes are arranged at the liquid cooling plate. The one or more through-holes are in communication with a cooling liquid flow channel inside the liquid cooling plate and sealed by a thermo-melt material. The thermo-melt material melts when a battery corresponding to one of the through-holes sealed thereby experiences thermal runaway. The battery liquid cooling device provides a normal cooling function when a battery functions normally, and functions as a fire extinction device when the battery experiences thermal runaway. By arranging the one or more through-holes at the liquid cooling plate and sealing the through-holes with the thermo-melt material, the battery liquid cooling device of the present invention has a very simple structure because no additional components and accompanying weight are added thereto, thereby ensuring no decrease in an energy density of a battery system. The battery liquid cooling device of the present invention can operate autonomously without manual intervention, thereby saving labor, and ensuring safety when a battery is in use.
