Description

Technical Field

[0002] New energy vehicles refer to vehicles that use unconventional automotive fuels as their power source or use conventional automotive fuels, adopt new on-board power devices, and integrate advanced technologies in vehicle power control and drive to form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. New energy vehicles mostly use batteries as their power source, and batteries will generate heat after working, so it is particularly important to dissipate heat from the batteries.

[0003] Although the existing technology can dissipate heat from the battery, most of them are done by installing heat dissipation holes or heat sinks on the battery box, or by using a built-in cooling fan, which easily forms local heat dissipation, and the internal heat is not easy to dissipate, resulting in poor heat dissipation effect. At the same time, most of the heat dissipation devices currently on the market for new energy vehicle battery management cannot adopt an effective and universal fixed structure according to car batteries of different sizes when in use. When the car is driving bumpy, it will shake, which is easy to cause battery damage and affect the operation of the battery. Utility Model Content
