AI Technical Summary
Existing photovoltaic backsheets have coupling issues in terms of noise isolation and heat dissipation. They cannot effectively block substation noise and have low heat dissipation efficiency, resulting in a decrease in photovoltaic power generation efficiency. Furthermore, existing solutions occupy a large space or generate secondary noise.
A modular sound-absorbing and heat-dissipating structure is adopted, which combines a micro-perforated plate and a hybrid diaphragm resonator. The micro-perforated plate absorbs mid-to-high frequency noise and converts it into vibration, which drives airflow to achieve heat dissipation. The hybrid diaphragm resonator converts mid-to-low frequency noise into vibration energy, which promotes gas flow.
It integrates noise absorption and heat dissipation functions in a small structure, improving noise reduction and heat dissipation efficiency, reducing space occupation, adapting to photovoltaic panels of different specifications, broadening the noise reduction frequency band, and improving photovoltaic power generation efficiency.
