An immersed liquid-cooled battery pack structure

Abstract

The utility model relates to battery thermal management technical field especially, more particularly to a kind of immersed liquid-cooled battery pack structure, including box and box cover being installed on box, two mounting racks are installed in the box, and multiple groups of array arrangement battery unit are installed between two mounting racks, cooling liquid that battery unit is completely immersed is also equipped in the box, battery management unit is installed on the outer wall of box, and the side of battery management unit is equipped with the heat dissipation component installed on the outer wall of box;The heat dissipation component includes the heat conduction plate installed on the side wall of box;The immersed liquid-cooled battery pack structure can make cooling liquid completely contact with the surface of multiple groups of battery unit, improve heat exchange efficiency, and the heat dissipation efficiency is high, especially suitable for high power density battery scene, can also simultaneously heat dissipation to battery management unit, and overall volume is smaller, can improve space utilization, it is favorable to reduce pack volume or increase battery capacity.
