The present disclosure describes an induction charging device for a partially or fully electrically operated motor vehicle. The induction charging device includes at least one charging coil and a temperature-control assembly including a fluid pipe for a liquid fluid. The charging coil is inductively couplable to a primary coil such that a battery can be inductively charged in the motor vehicle. The charging coil is heat-transmittingly connected to the fluid pipe such that the waste heat from the charging coil can be transmitted to the fluid. The induction charging device further includes a metal shielding plate for shielding electromagnetic field emissions, and a ferrite assembly for directing an electromagnetic alternating field. The charging coil is arranged in the fluid pipe such that the fluid can flow around it on all sides. The charging coil is secured in the fluid pipe directly or via a retaining device.

The present disclosure disclosed a wireless charging module manufacturing method. The method includes the following steps: forming a first heat dissipating layer on a surface of a coil; and securing a magnetic shield part to the surface of the coil away from the first heat dissipating layer. A wireless charging module is manufactured by the method. By completely cover the coil with the first heat dissipating layer in the present disclosure, the first heat dissipating layer possesses excellent heat radiation, effectively improving the heat dissipation of the coil. The thickness of the first heat dissipating layer is controllable. Therefore, an effective and highly stable heat dissipating performance can be provided without increasing the thickness and cost of the wireless charging module.
