Abstract

The invention discloses a heat conduction structure and method for lithium battery heat management, and relates to the technical field of lithium batteries. The heat conduction structure comprises a lithium battery body and a lithium battery shell, the outer surface of the lithium battery body is wrapped by a fixing assembly, a heat conduction mechanism and a push-pull operation unit are arranged in the lithium battery shell, the heat conduction mechanism comprises an air cooling unit and a heat conduction copper block, and one side of the heat conduction copper block is in close contact with the surface of the lithium battery body. According to the heat conduction structure and method for lithium battery heat management, the heat conduction mechanism and a battery installation unit are arranged, air cooling is combined with heat conduction of conductor materials through heat conduction copper block, fins and the air cooling unit, and through installation between an installation plate and an installation groove, the heat conduction efficiency of a lithium battery can be improved; and moreover, contact between the heat conduction copper block and the lithium battery can be effectively improved, so that influence on heat conduction caused by deviation of the heat-conducting copper block and the lithium battery due to shaking is avoided.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a heat conduction structure for thermal management of lithium batteries and a method thereof. Background technique [0002] At present, the thermal management of the power lithium battery system can be divided into four main categories, natural cooling, air cooling, liquid cooling and phase change material cooling. First, the rate of natural cooling is relatively slow. Air cooling is not enough heat dissipation when there is a lot of heat in the use of lithium batteries. At the same time, the energy loss required by liquid cooling is relatively expensive, and the temperature that can be cooled by phase change material cooling is maintained at 25-40°C. When the temperature is too low, it cannot play a role. [0003] Referring to the Chinese patent, the patent name is: A thermal management structure and method for a prismatic lithium battery pack (patent publication numbe...
