  • Pumped loop refrigerant system for windings of transformer
    Patent number: 8436706
    Abstract: A pumped loop cooling system is provided to cool a hollow winding of a transformer utilizing a two phase vaporizable dielectric refrigerant. A liquid refrigerant pump circulates the refrigerant into a transformer and through a copper tube winding of the transformer where the refrigerant at least partially vaporizes in removing heat from the transformer. The refrigerant is then circulated to a condenser and then back to the pump.
    Type: Grant
