Abstract
A system for cooling a power transformer wherein cryogen in liquid or solid form is sprayed into a vaporizer or directly onto a power transformer radiator and the vaporizing and/or sublimating cryogen cools a cooling fluid within the vaporizer or cools the radiator directly to provide cooling to the power transformer.
Claims8
A method for cooling a power transformer comprising:
- (A) drawing air into a vaporizer having an intake and an exhaust and having a converging/diverging configuration from the intake to the exhaust, and passing air through the vaporizer from the intake to the exhaust;
- (B) passing liquid cryogen from a storage vessel to the vaporizer, spraying liquid cryogen into the vaporizer between the intake and the exhaust, and cooling air within the vaporizer by direct heat exchange with the liquid cryogen;
- and
- (C) passing cooled air from the vaporizer to a power transformer to provide cooling to the power transformer.

Apparatus for cooling a power transformer comprising:
- (A) a vaporizer having an intake and an exhaust and having a converging/diverging configuration from the intake to the exhaust, and having means for drawing cooling fluid into the intake of the vaporizer and for ejecting cooling fluid out from the exhaust of the vaporizer;
- (B) a liquid cryogen storage vessel and means for passing liquid cryogen from the storage vessel to the vaporizer between the intake and the exhaust;
- and
- (C) a power transformer positioned to be contacted by cooling fluid ejected out from the exhaust of the vaporizer.
