Use of solar photovoltaic powered fans to reduce peak temperatures in outdoor cabinets

摘要

Peak temperatures in uninsulated outdoor cabinets containing telephone equipment can rise significantly due to solar radiation. Solar-photovoltaic-powered DC mixing fans can be used to reduce these peak temperatures by mixing the air inside the cabinet. Tests conducted at the Bellcore Thermal Test Facility demonstrated that a significant reduction in peak temperature could be obtained in cabinets with heat loads above 200 W.
