AI Technical Summary

Technical Problem

Existing wireless chargers have poor heat dissipation when charging at high power, and are unable to effectively reduce the temperature of the charger and mobile terminal, affecting charging efficiency and device life.

Method used

A dual direct-cooling wireless charging component is adopted, including a magnetic emission module, a first and a second refrigeration component in the shell. Semiconductor refrigeration sheets and heat dissipation components are used to cool the magnetic emission module and the mobile terminal respectively. The first refrigeration component directly cools the coil and magnetic parts through the concave cavity structure, and the second refrigeration component directly cools the mobile terminal through the shell.

Benefits of technology

The heat dissipation effect during high-power wireless charging is significantly improved, ensuring that the charger and mobile terminal remain low in temperature under high power, extending device life and improving charging efficiency.
