Abstract
A heat sink includes a substrate, a heat dissipation structure, and a refrigerating medium. The heat dissipation structure includes a connection part and a fin part that are of an integrated structure, the connection part is connected to the substrate, the fin part and the connection part are disposed at an included angle, a fin root of the fin part is connected to the connection part, and a fin top of the fin part is far away from the connection part, a cooling flow channel is disposed in the heat dissipation structure, and at least a part of the cooling flow channel is located in the fin part. The refrigerating medium flows in the cooling flow channel to dissipate heat from the substrate. A heat conduction capability of the heat sink can therefore be improved, and heat dissipation reliability is ensured.
