AI Technical Summary
Existing wireless chargers have low heat dissipation efficiency and cannot meet the requirements for rapid heat dissipation, resulting in heat accumulation during charging, which may lead to reduced charging power or safety hazards.
A flow guide structure and a fan are set on the back of the charging component. The airflow is introduced through the flow guide channel and carries away the heat of the charging component. The heat dissipation is achieved by continuous airflow circulation. A second fan is added to improve the heat dissipation efficiency. The airflow suction effect is enhanced by the coordinated work of the flow guide structure and the fan.
It achieves efficient heat dissipation of the charging components, avoids the reduction in charging power or safety hazards caused by heat accumulation, meets the requirements of rapid heat dissipation, and improves the overall heat dissipation efficiency of the charging device.
