WATER COOLED TRANSFORMER, CAPABLE OF COOLING THE TRANSFORMER BY CIRCULATING THE WATER INSIDE THE SECONDARY COIL

摘要

PURPOSE: A water-cooled transformer is provided to reduce the manufacturing cost of the transformer by eliminating the separate radiator.;CONSTITUTION: A primary coil(120) is wound around a iron core(110) being perpendicularly installed. The primary coil is spirally wound around the outer circumference of the iron core installed perpendicularly. A secondary coil(130) is spirally wound around the outer circumference of the primary coil. The secondary coil is made of the copper material. The secondary coil is formed in shape of hollow capable of circulating the water. The secondary coil is spirally wound two to three times with the first extension part as the reference. A second extension unit corresponding to the first extension unit is formed on the end of the secondary coil.;COPYRIGHT KIPO 2011
