In the embodiment of the present disclosure, the outer surface of the decoration 12 is planar, and the inner surface of the decoration 12 is recessed toward the outer surface to form the receiving groove 121, that is, the thickness of the decoration 12 at the receiving groove 121 is greater than the depth of the receiving groove 121. The outer surface in the plane shape can enable the protective shell 100 to be attached to the surfaces of different devices, and the application range is wide.

In addition, the area of the through hole 111 may be greater than, less than, or equal to the size of the notch of the accommodation groove 121. The shape of the through hole 111 may be the same as or different from the shape of the notch of the receiving groove 121, and both the area and the size of the through hole 111 may be designed according to the design requirement and the size of the heat dissipation assembly, which is not limited herein.

Further, the first magnetic member 31 may be fixed to the first surface of the heat sink by means of glue and/or grooves. In some embodiments, as shown in fig. 4, the heat sink is provided with a first groove 221 on the first surface, and the first magnetic member 31 is received in the first groove 221 such that the surface of the first magnetic member 31 is lower than or flush with the first surface of the heat sink.

The first magnetic element 31 is accommodated in and fixed to the heat sink through the first groove 221, and the first magnetic element 31 is fixed to the first surface of the heat sink through dispensing, so that the first magnetic element 31 and the heat sink can be fixed more firmly, and after the first magnetic element 31 is accommodated in the first groove 221, the surface of the first magnetic element 31 can be lower than or flush with the first surface of the heat sink.
