    Abstract

    The thermal behavior of electronic cabinets for outdoor installation is analyzed. As the correct working condition of circuit boards requires a temperature-conditioned housing, the thermal design of the cabinet structure must be carefully foreseen from both the insulating and cooling point of view.

    After a short review of some technical solutions for passively conditioned cabinets, an approximate physical model is presented that is able to simulate with a sufficient degree of generality the transient thermal behavior of the structure as a whole. Several examples of numerical solutions are reported relating to different kinds of cabinets with or without natural air ventilation. The effect of thermal storage inside the cabinet is analyzed, too.

    The numerical simulations show that for this kind of application any thermal calculation procedure must take into account the transient effect in all structural components.
