SUMMARY
Determining the orifice size for cooling an electronics cabinet requires careful consideration of multiple factors, including airflow type (forced or natural), the heat load of the components, and the cabinet's specifications such as size and material. The target outlet temperature of 140°F must be aligned with the heat generated by the electronics, which operates at an inlet temperature of 70°F. Key considerations also include the cabinet's rating (e.g., NEMA 4X) and whether the application is indoors or outdoors, as these factors significantly influence cooling efficiency.
