Roller cooling lithium battery pack

Abstract

The invention relates to a roller heat dissipation lithium battery pack. The roller heat dissipation lithium battery pack includes a closed casing, an electric contact plate coupled with an electrical appliance, a battery core and a roller-shaped battery rack; one of the battery racks An electric contact ring is installed on the end face; each of the battery cores is electrically connected to the electric contact ring and then distributed uniformly in the circumferential wall of the battery rack; the inner peripheral wall of the battery rack is also fixed with the battery The core is electrically connected and its position is the pressure-sensitive piece facing it; the battery frame can rotate freely around the axis of the battery frame itself on the surface of the electric contact plate, and the electric contact ring and the electric contact ring are in the process of rotation. The contact plate is kept in electrical contact; a closed flow guide tube is connected to both sides of the housing, and a driving pump is installed on the guide tube; The liquid regulating tube; the battery pack can effectively cool itself and prolong the service life; at the same time, it can keep the inside of the battery pack clean.

Description

technical field [0001] The invention relates to an energy battery pack, especially a lithium battery pack. Background technique [0002] The voltage of a single-cell lithium battery is only about 3.7 volts, and the capacity of the battery cannot be infinitely large. Therefore, in actual use, single-cell lithium batteries are often processed in series and parallel to meet the requirements of different occasions; traditional lithium batteries The arrangement is relatively dense, and a lot of heat is generated during use. Because it is sealed by the shell, the heat generated by the battery pack is concentrated and difficult to dissipate. Therefore, the battery pack is prone to overheating, and the battery working at a higher temperature is prone to aging. , the service life of the short battery pack is significantly reduced; especially in summer, the battery pack is prone to high temperature fires, explosions and other safety hazards.
