Document Type and Number:
WIPO Patent Application WO/2019/124755
Kind Code:
A1
Abstract:
One embodiment of the present invention relates to a wireless charging apparatus provided with a wireless communication coil. The wireless charging apparatus, according to the one embodiment of the present invention, comprises: a substrate; a shielding material disposed on the substrate; a wireless charging coil module disposed on the substrate and the shielding material; a first heat dissipation member disposed on the upper surface of the substrate; a second heat dissipation member disposed on the lower surface of the substrate; and a wireless communication coil pattern disposed on the upper surface of the substrate and disposed so as to be spaced apart from the first heat dissipation member. The second heat dissipation member comprises: a grounding heat dissipation part disposed on the edge region of the substrate; a main heat dissipation part disposed in a region overlapping with the first heat dissipation member; and a connecting heat dissipation part for connecting the grounding heat dissipation part and the main heat dissipation part.
