1. A heat dissipation assembly, comprising:
a heat dissipation layer main body including at least one first side, at least one arc-shaped corner side and at least one second side, wherein a first side, an arc-shaped corner side and a second side are sequentially connected, extending directions of the first side and the second side intersect with each other;
at least one first bending portion, a first bending portion being connected to the first side;
at least one second bending portion, a second bending portion being connected to the second side; and
at least one corner bending portion, a corner bending portion being connected to the arc-shaped corner side, and the corner bending portion being provided with at least one first opening therein;
wherein the first bending portion, the corner bending portion and the second bending portion are sequentially connected; and
a first opening is in a shape of a strip, and the first opening extends substantially in a radial direction of the arc-shaped corner side; in a case where the corner bending portion is provided with a plurality of first openings therein, the plurality of first openings are sequentially arranged at intervals in an extending direction of the arc-shaped corner side;
wherein the first bending portion and/or the second bending portion is provided with at least one second opening therein;
wherein a second opening is in a shape of a strip, and the second opening extends substantially in an extending direction of a side, connected to the first bending portion or the second bending portion where the second opening is located, of the heat dissipation layer main body;
in a case where the first bending portion and/or the second bending portion is provided with a plurality of second openings therein, the plurality of second openings are arranged in at least one row, second openings in each row are sequentially arranged at intervals in a first direction; in a case where the plurality of second openings are arranged in a plurality of rows, the plurality of rows of second openings are arranged in parallel in a second direction;
wherein the first direction is the extending direction of the side, connected to the first bending portion or the second bending portion where the plurality of second openings are located, of the heat dissipation layer main body, and the second direction intersects the first direction.
