Electrical and electronic equipment as well as components typically are housed in electrical enclosures designed to provide protection from the external environment. These components and equipment are sensitive to temperature changes, and at high temperatures, a number of issues can arise. They include drive performance derating and IC-based devices adversely affected by erratic output or voltage migration. Additionally, the properties of silicone materials change with temperature extremes. In wiring insulations, elasticity and strength are reduced along with experiencing a temporary increase in ductility and atomic mobility.
In short, exposing electronics to high temperatures can have a significantly harmful impact on equipment performance and useful life. Given this risk, there is a strong need for finding a way keep an electrical enclosure cooled to prevent overheating electronics.
