The invention discloses a wireless charging device, comprising: a magnetic conductive plate; a charging coil disposed on the magnetic conductive plate; and an adapting panel located above the chargingcoil and configured to carry a power receiving device. The adapting panel is in contact with a portion of the charging coil and cooperates with the charging coil to form a heat dissipation channel. By setting the heat dissipation channel between the adapting panel and the portion of the charging coil, heat generated by the current-loaded charging coil can be dissipated through the heat dissipation channel, thereby reducing heat transferring to a power receiving device and preventing the power receiving device from affecting charging due to overheating.
Description
technical field [0001] The present invention relates to the technical field of wireless charging, in particular to a wireless charging device. Background technique [0002] A current wireless charging device generally includes an adapter panel for carrying a power receiving device and a charging coil located under the adapter panel. The power receiving device may be a device to be charged such as a smart phone or a medical device. There is a power receiving coil in the power receiving device. When the power receiving device is placed on the matching panel, the power receiving coil is aligned with the charging coil. Using the electromagnetic induction phenomenon between the two coils, the power in the wireless charging device can be transmitted to the power receiving device. In-device to realize wireless charging of powered devices. [0003] However, in the prior art, in order to ensure the efficiency of wireless charging, the distance between the receiving coil and the char...
