Abstract

本实用新型涉及铝制散热片技术领域，尤其涉及一种拼接式铝制散热片，包括有散热片组件，还包括有散热风机、拼接组件、吊装板；散热片组件的前端设置有散热风机；散热片组件的上端设置有吊装板；散热片组件的下端设置有拼接组件。本实用新型通过拼接组件将发热器件固定在散热片组件上，设备固定盒将其内部的发热器件固定，再配合设备固定盒上端面的导热相变片将导热铜片与发热器件之间的缝隙填充，从而有效降低导热热阻，从而提高导热散热效率，当发热器件的热量通过导热相变片以及导热铜片传导至铝制散热片时，巨大的铝制散热片散热面积有效提高散热速度，配合散热风机吹风，极大加速了铝制散热片周围空气的流动，从而提高热交换速度，加速铝制散热片散热。
