Cooling Fan Preventive Maintenance
Cooling fan is essential component in many drive products. It provides a thermal management by creating an airflow, thus lowering the temperature inside the drives. It provides high efficiency and performance by removing the heat generated inside the drive. There are several different fan options available: AC fan, DC fan and newest EC fan. They all have different characteristics in terms of operation. The lifetime of a fan is highly dependent on the application conditions and is affected by both electrical and environmental factors.Common stresses that influence fan reliability are temperature, temperature change, humidity, humidity change, voltage, corrosion, vibration, mechanical shock and radiation. Since several failures in the field can be traced back to thermal related issues, the reliability of cooling fans is a critical part of the overall reliability of thermal management in drives.
