[0023] The utility model realizes effective heat dissipation of the second coil assembly 22 by providing a semiconductor cooling plate 23 in contact with the second coil assembly 22, and dissipates heat to the semiconductor cooling plate 23 through the radiator 24 and the turbo fan 25, which greatly reduces the temperature of the second magnetic wireless charging part 21 during operation, ensures the charging efficiency of the mobile phone wireless charging, and can also take away some of the heat generated by the mobile phone during wireless charging, thereby improving the user experience.

The third heat dissipation hole 32 is a plurality of circular holes arranged in an array, which is used to dissipate heat from the third coil assembly.

[0031] Since the charging power of headphones and smart watches is relatively low and the heat generated is not much, the heat dissipation requirements can be met directly through the heat dissipation holes.
