Transformers generate heat during operation. Insufficient enclosure ventilation may impair operating conditions and maintenance. Before designing, confirm transformer capacity, heat loss, ambient temperature, enclosure dimensions, airflow direction, and installation location.

Depending on project needs, enclosures may require louvers, vents, fans, cooling ducts, or thermal management structures. The location, size, and orientation of vent openings also affect ingress protection (dust/water) and personnel safety. This article covers key considerations across natural ventilation, forced cooling, heat exhaust, and protective structures.
