Oil Forced Air Forced Cooler:

An OFAF cooler, also known as an "Oil Forced Air Forced" cooler, is a type of cooling system commonly used in transformers.

The OFAF cooler works by circulating oil through the transformer core and windings to absorb heat generated by the electrical current. The heated oil is then pumped to an external heat exchanger where it is cooled by forced air. The cooled oil is then returned to the transformer to absorb more heat, completing the cycle.

The OFAF cooler is an effective method for dissipating heat and ensuring the proper functioning of a transformer. It is commonly used in high-voltage and high-power transformers, particularly those used in the power generation and transmission industries.

Application: Transformer Cooling.
