TRANSFORMER HAVING STACKED PASSCORE

DISCLOSED HEREIN IS A TRANSFORMER HAVING A STACKED PASSCORE (160, 260). A PRIMARY COIL (140, 240) PROVIDED IN AN E-SHAPED CORE (110, 210). A SECONDARY COIL (150, 250) IS DISPOSED ABOVE THE PRIMARY COIL AT POSITION SPACED APART FROM THE PRIMARY COIL BY A PREDETERMINED DISTANCE. A PASSCORE IS PROVIDED BETWEEN THE PRIMARY COIL AND THE SECONDARY COIL TO PREVENT THE CORE FROM OVERHEATING. AN AUXILIARY PASSCORE (270) IS STACKED ON EITHER OR EACH OF UPPER AND LOWER SURFACES OF THE PASSCORE. THE AUXILIARY PASSCORE HAS HOLLOW PIPE SHAPE SO THAT AIR PASSES THROUGH THE AUXILIARY PASSCORE. AIR THAT PASSES THROUGH THE AUXILIARY PASSCORE DISSIPATES HEAT, THUS PREVENTING HEAT FROM BEING TRANSFERRED TO THE CORE OR THE PASSCORE, THEREBY REDUCING THE TEMPERATURE OF THE CORE OR THE PASSCORE.
