PUMPED LOOP REFRIGERANT SYSTEM FOR WINDINGS OF TRANSFORMER

摘要

A pumped loop cooling system (10) is provided to cool a hollow winding (36) of a transformer (30) utilizing a two phase vaporizable dielectric refrigerant. A liquid refrigerant pump (20) circulates the refrigerant into a transformer (30) and through a copper tube winding (36) of the transformer where the refrigerant at least partially vaporizes in removing heat from the transformer (30). The refrigerant is then circulated to a condenser (40) and then back to the pump (20).
