摘要： A transformer has a vertical winding assembly formed of a stack of pancake coils sandwiched between electrically insulating bases each provided on its surface contacted by an associated one of pancake coils with a plurality of cooling grooves extending in spaced relationship along turns of a rectangular electrically conductive wire forming the pancake coil and opening on the upper and lower portions of the base. A liquid refrigerant sprinkled on the winding assembly is arranged to flow through the cooling grooves via the upper open ends and be discharged via the lower open ends.
