A wireless charging device is provided. The plurality of protrusion portions are utilized to form the first gap between the top plate and the mobile device, so as to increase the distance formed between the top plate and the mobile device. Consequently, the first interfacial thermal resistance formed between the transmitter coil assembly and the receiver coil located in the mobile device is increased, and the second heat source generated from the transmitter coil assembly is dissipated through the wireless charging device instead of being transferred to the receiver coil located in the mobile device. In that, the temperature of the mobile device is controlled to be under the tolerance temperature threshold value during the charging process of the wireless charging device. Consequently, the charging power is enhanced, and the charging speed is increased.
