The battery pack cooling structure provided by the invention has the characteristics of highpracticability and excellent thermal management performance.

Description

technical field [0001] The invention relates to the technical field of power batteries, in particular to a battery pack cooling structure and the battery pack. Background technique [0002] With the progress of society and the rapid development of science and technology, in the context of limited natural resources, the emergence of new energy has obviously solved the current problem of energy scarcity. New energy vehicles, as environmentally friendly and new concept vehicles, are currently appearing on the market in increasing numbers. As one of the core components of new energy vehicles, the power battery pack has attracted much attention for its safety performance and endurance performance. Among them, the cooling system is an important part of the power battery pack. Since it can cool the battery pack to prevent dangerous situations caused by overheating of the battery, it has a great impact on the performance, life and safety of the battery. [0003] The cooling system...
