Beschreibung
Zusammenfassung:	The wireless charger comprises a shell, a coil and a circuit board, a containing cavity is formed in the shell, the coil and the circuit board are arranged in the containing cavity, the upper end of the coil is connected with a heat insulation structure, the lower end of the coil is connected with a first heat conduction structure, and the first heat conduction structure is connected with a second heat conduction structure. The circuit board is placed below the first heat conduction structure, and a cooling fin is connected below the first heat conduction structure; a heat insulation sheet is connected between the cooling fin and the circuit board, and a second heat conduction structure is connected below the circuit board; a linear heat conduction groove is formed in the inner side wall of the shell, and the linear heat conduction groove is communicated with the containing cavity. According to the utility model, heat generated by the coil is led to the lower part of the coil for heat dissipation, the overall
