Abstract

The invention discloses a phase change material for thermal management of a communication base station battery. The phase change material comprises a battery pack case, wherein a box body cover is arranged above the battery pack box body; phase-change material energy storage rods are arranged among the four battery packs. A movable groove is formed in an inner cavity of the phase-change material energy storage rod; a telescopic mechanism is arranged in an inner cavity of the movable groove; the phase change material energy storage rod comprises a first heat conduction silicon wafer, a shell, an arc wall and a phase change material. Arc walls are arranged on the four sides of the shell. First heat conduction silicon wafers are attached and fixed to the outer walls of the four arc walls. A phase change material is filled between the shell and the movable groove. According to the phase change material for thermal management of the communication base station battery, after the phase-changematerial absorbs heat and is saturated, the inner cavity of the stretching column contacted with the second heat-conducting silicon wafer is heated to expand to form an air pressure difference, the telescopic rod is pushed to move upwards in the inner cavity of the stretching column, the contact plate is contacted with the graphite layer at the bottom of the box cover for secondary heat dissipation, and heat management is performed on the battery pack.

Description

technical field [0001] The invention relates to the technical field of thermal management of communication base station batteries, in particular to a phase change material used for thermal management of communication base station batteries. Background technique [0002] The large-capacity lead-acid battery used as a backup power supply is the guarantee for the power supply of the communication base station. In special cases such as power outages, the reliability of the backup power supply is particularly important. When the backup battery pack is working, it will generate a lot of heat. The thermal management of the battery is protected to improve the stability of the battery pack and prolong the service life of the battery pack. [0003] However, in recent years, the phase change material technology that has emerged in the research of battery thermal management has achieved good results. Phase change materials have good heat storage and heat conduction effects. However, the...
