Abstract
A radiator and an electrical device. The radiator includes a heat dissipation substrate and a heat dissipation assembly, wherein the heat dissipation substrate is provided with an installation position for installing the heat dissipation assembly, the installation position is provided with a stress release groove, and the heat dissipation assembly is welded on the installation position. According to the radiator provided in the present application, the stress release groove is provided in the installation position for installing the heat dissipation assembly on the heat dissipation substrate, such that the installation position is isolated from the connecting position of the heat dissipation assembly to form an island structure, and the island structure reduces stress pulling caused by thermal deformation of the two materials of the heat dissipation assembly and the radiator.
