Most enclosure manufacturers provide thermal management calculation tools to properly size enclosures (non-temperature controlled) for specific applications. In addition to the physical size needed for a control system, enclosure sizing needs to ensure that there is sufficient surface area and adequate cubic air space in the enclosure to dissipate the heat needs. Reducing heat generated by all of the components inside the enclosure reduces the required enclosure size. In this way, minimizing enclosure size can help reduce the total system cost.
