Abstract
A sheet-wound transformer comprises a magnetic core, a number of coil windings formed of sheet conductors wound around the magnetic core, and a plurality of cooling panels inserted in the coil windings. A number of ribs are provided in each cooling panel so as to extend in parallel with each other for guiding the flow of a coolant therethrough. Leading and trailing ends of the ribs are located respectively on two lines, the inclination of each line being varied between the central portion and end portions thereof, so that the displacement between two ends of adjacent pair of ribs located on an end portion of the line is made larger than the displacement between two ends of ribs located on the central portion of the line.
