一种易于携带的随身wifi充电宝

Abstract

本实用新型公开了一种易于携带的随身wifi充电宝，属于电子设备技术领域，其中连接件包含底板及两侧对称分布的阶梯式双层支撑结构。上层支撑通过螺钉固定电路板，下层支撑固定电池组，实现空间分层与模块化布局，关键芯片与电路板接触面填充导热硅胶以提升热传导效率。电路板下方通过螺钉紧贴金属导热板，导热板下表面固定阵列式散热鳍片。散热鳍片高度与支撑结构平齐，且支撑结构间的空隙与外壳两侧的散热槽精准对齐，形成高效直线散热风道。通过阶梯支撑实现紧凑抗冲击布局，多级散热系统(导热介质→金属导热板→散热鳍片→定向风道)有效解决高温降频问题，整体兼具高可靠性、便携性与优异的散热性能。
