Magnetic wireless charger

The invention discloses a magnetic attraction wireless charger which comprises a lower shell, a fan cover, a PCB and an upper cover. The lower shell is located below the first open end of the fan cover, a first ventilation hole is formed in the lower shell, and the first ventilation hole is used for enabling air to enter the first open end; the upper cover is located above the second open end of the fan cover, the upper cover is connected with the lower shell, and a second ventilation hole is formed in the upper cover and used for leading out air in the fan cover. And the space among the first vent hole, the fan cover and the fan and the second vent hole form an air duct. When the mobile phone is charged, the fan rotates, and negative pressure is formed in the space between the fan cover and the fan, so that air enters the space between the fan and the fan through the first vent hole and then is discharged through the second vent hole, heat of the mobile phone mainboard is taken away, the mobile phone mainboa
