A wireless charging device according to an embodiment may improve charging efficiency and heat dissipation characteristics by using a three-dimensional structure in a magnetic portion. In detail, by increasing the thickness of a magnetic portion in the vicinity of a coil portion where electromagnetic energy is concentrated during wireless charging, and reducing the thickness of the center of the magnetic portion where the electromagnetic energy density is relatively low, wireless charging efficiency may be increased, and heat generated from the magnetic portion may be reduced. Therefore, the wireless charging device can be effectively used for a mobile tool, such as an electric vehicle, which requires large amount of energy transmission between the transmitter and the receiver.
根据实施例的无线充电装置可通过使用磁性部分中的三维结构来改进充电效率和散热特性。详细地,通过增加于无线充电期间电磁能量集中的线圈部分附近的磁性部分的厚度,以及减少电磁能量密度相对低处的磁性部分中心的厚度,可以增加无线充电效率,并且可以降低从磁性部分所产生的热量。因此,无线充电装置可有效地用于需要在发射器和接收器间进行大量能源传输的移动工具,如电动车。
