Abstract

A heat dissipation assembly includes a heat dissipation layer main body including at least one first side, arc-shaped corner side and second side, at least one first bending portion, second bending portion and corner bending portion. A first side, an arc-shaped corner side and a second side are sequentially connected. A first bending portion, a corner bending portion and a second bending portion, that are sequentially connected, are respectively connected to the first side, the arc-shaped corner side and the second side; the corner bending portion is provided with at least one first opening therein. A first opening is in a shape of a strip, and extends substantially in a radial direction of the arc-shaped corner side. In a case where the corner bending portion is provided with first openings therein, the first openings are sequentially arranged at intervals in an extending direction of the arc-shaped corner side.
