 Enclosure cooling fans are one type of cooling device used to help keep heat producing electrical components from overheating. Fans are unique in that they are considered to be an open loop cooling system whereas air to air heat exchangers and enclosure air conditioners are closed loop systems.
An open loop cooling system means the ambient air enters the cabinet and is passed over the heat producing components to keep hot spots from forming and is then expelled from the enclosure. Even in the cleanest environments, enclosure cooling fans should have some type of air filtration to keep particulates from entering the enclosure. Enclosure cooling fan issues often go unnoticed until electrical components begin to malfunction and eventually fail. Regular inspections and routine filter maintenance usually help keep potential problems from happening but issues can arise even if maintenance is regularly done. Read More >> Comments are closed.
