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

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.<
