Heat inside electronic enclosures is a hazard that is often underestimated. Air-conditioning electronic enclosures can ensure a constant level of operational reliability and prolong service life for electronic systems under difficult ambient conditions.
Hot spots are areas inside the electronic enclosure that are not involved in natural convection. Formed mainly around the top of the electronic enclosure, hot spots occur due to undercuts or installations that prevent an exchange of air. A rise in ambient temperature can intensify the severity of hot spots.
