Kooltronic Enclosure Cooling Design Guide

Heat-producing components used in electronic kiosks, ATMs, and digital signage present the problem of dissipating the heat generated before damage can occur to heat-sensitive parts. In many cases, the problem can be solved by ventilation, using simple air moving devices (fans and fan trays). However, in more and more applications (especially enclosures in outdoor applications) - the available ambient air is too warm or too contaminated to be used for the safe dissipation of unwanted heat. Under those conditions, the life expectancy and performance of sensitive components may be adversely affected, often causing equipment malfunctions, slowdowns, or failures.

In forced convection cooling of kiosks, ATMs, and other electrical enclosures, the cooler ambient air is drawn or forced through the components in an enclosure and discharged. When electronic/electrical enclosures are sealed to keep out moisture, dust, dirt, and other contaminants, the heat generated by the components is trapped and closed-loop cooling (enclosure air conditioneror heat exchanger) is needed to maintain the optimum environment for the components.
