AI Technical Summary
Technical Problem
The existing phosphor wheel devices suffer from low cooling efficiency due to airflow stagnation in the corrugated plate shape of the heat exchange portion, leading to inefficient heat dissipation.
Method used
A phosphor unit with a peripheral wall and heat receiving fins that redirect airflow to enhance circulation and improve heat dissipation, combined with a thermoelectric conversion element for further heat management.
Benefits of technology
The redesigned airflow circulation and heat dissipation system significantly enhances the cooling efficiency of the phosphor wheel, ensuring effective temperature regulation and prolonged device performance.
