Basics of thermal management in enclosures

摘要

To prevent the premature failure of equipment within an electrical enclosure, thermal management is key. There are two ways of cooling an enclosure: by natural convection and forced convection. Natural convection. When natural convection is used for an enclosure, cool air will naturally flow through the bottom, making the heat rise and then flow out of the top. This is a very slow and gradual process and cannot be controlled, which means it is a risky choice for the components inside.
