The invention discloses a cooling structure and a wireless charging device. The cooling structure comprises a first shell body, a first heat source which is arranged in the first shell body, a second shell body, a second heat source which is placed in the second shell body, and a shield layer which is located between the first shell body and the second shell body. The surface, back on to the second shell body, of the shield layer is provided with cooling fins and heat conductive pieces. The heat conductive pieces are connected with the first heat source and the cooling fins. The technical scheme can achieve the reasonable cooling of the wireless charging device, and provides a good working environment for all its internal functional modules, thus enhancing the long term reliability and market acceptance of the wireless charging device.
