AI Technical Summary
Technical Problem
The existing liquid cooling units used for battery pack thermal management are energy-intensive and have low safety, posing a risk of thermal runaway and fire, which affects the safety of battery pack use.
Method used
The device employs a phase change heat pipe assembly and a spray mechanism. The phase change heat pipe assembly includes first and second heat exchange ends, and a liquid storage component stores coolant. The spray mechanism sprays coolant when the battery pack experiences thermal runaway, and works in conjunction with a radiator and a heating component for thermal management.
Benefits of technology
Reduce thermal management energy consumption, improve battery pack safety, prevent thermal runaway, and save construction costs and space.

Abstract
The utility model relates to the technical field of energy storage, and specifically provides a heat management system for battery pack and energy storage system, aims at solving the problem of high energy consumption of the existing heat management system and leading to poor heat management effect. The heat management system of the application heat management system includes phase change heat pipe assembly, liquid storage component and spraying mechanism, the first heat exchange end of phase change heat pipe assembly is adjacent to the setting with battery pack and is used for heat exchange with battery pack, the liquid storage cavity of liquid storage component stores cooling liquid, at least a part of the second heat exchange end of phase change heat pipe assembly is soaked in cooling liquid, when the thermal runaway of battery pack occurs, the spraying mechanism can spray the cooling liquid in the liquid storage cavity to battery pack. The application can not only exchange heat between the cooling liquid in the liquid storage cavity and the second heat exchange end, thereby facilitating the heat management of battery pack, but also spray the cooling liquid to battery pack when the thermal runaway of battery pack occurs, without using both reducing energy consumption and improving safety.
