Abstract
A cooling system for a transformer comprises a fan duct and a housing which together enclose an interior space. A transformer located in the interior space is mounted on the fan duct, and has a plurality of core sections surrounded by windings and separated by gaps. An air channeling structure is located between the transformer and the fan duct. A cooling airflow path extends through the air channeling structure, and between core sections of the transformer.

A cooling system for a transformer, the cooling system comprising:
- a fan duct containing a fan;
- a housing affixed to the exterior of the fan duct, such that the housing and the fan duct together enclose an interior space;
- a transformer located in the interior space, mounted on the fan duct, and having a plurality of core sections surrounded by windings and separated by gaps;
- an air channeling structure located between the transformer and the fan duct, the air channeling structure comprising an orifice fluidly connecting the gaps between transformer core sections and the interior of the fan duct;
- and
- a cooling airflow path through the air channeling structure and the gaps between transformer core sections.
An air cooling method for a transformer in a housing attached to a fan duct, the method comprising:
- providing airflow with a fan in the fan duct;
- directing air through an air channeling structure between the transformer and the fan duct;
- and
- directing air between and around cores sections of the transformer.
