Abstract

The invention belongs to the technical field of batteries, and discloses a liquid cooling system and a battery pack, the liquid cooling system comprises a connecting pipe, a liquid cooling plate and a spray head, one end of the connecting pipe is communicated with the liquid cooling plate, the other end of the connecting pipe is communicated with the spray head, and when a battery unit is subjected to thermal runaway and even is on fire, cooling liquid in the liquid cooling plate can be sprayed out from the spray head; therefore, the effects of reducing the temperature in the battery box and extinguishing flames are achieved.

Description

technical field [0001] The present invention relates to the technical field of batteries, in particular to a liquid cooling system and a battery pack. Background technique [0002] Lithium-ion power batteries have become the mainstream battery products on the market due to their advantages of long life, low self-discharge rate, high specific power, high energy density and no pollution. However, when the lithium-ion battery is charged and discharged, its cells will generate a lot of heat, and this part of the heat needs to be discharged in time, otherwise there will be dangers such as battery fire or battery explosion. The existing heat dissipation method is to install a liquid cooling plate in the battery pack, connect the liquid cooling plate to the cooling liquid circulation pipe, and make the cooling liquid circulate in the liquid cooling plate to absorb the heat in the battery pack. [0003] However, the above method can only achieve a certain degree of cooling, and whe...
