AI Technical Summary

⚠Technical Problem

Poor heat dissipation and low charging efficiency in wireless charging modules are mainly due to poor heat dissipation of the charging coil and interference from the magnetic field by electronic components on the circuit board.

⚗Method used

A heat dissipation module is installed between the magnetic coil and the PCB assembly. The magnetic field interference of electronic components on the magnetic coil is reduced by a shielding structure. Electronic components are covered by a TEC heat dissipation structure and shielding components. Heat dissipation efficiency is improved by combining a cooling fan and auxiliary heat dissipation components.

🎯Benefits of technology

The heat dissipation efficiency of the magnetic coil has been improved, the magnetic field interference of the electronic components on the circuit board to the magnetic coil has been reduced, and the charging efficiency and heat dissipation effect of the wireless charging module have been improved.
