The present invention relates to a transformer coil cooling structure, and more specifically, to a transformer with improved cooling efficiency by effectively supplying insulation oil to the inside thereof. The transformer including an iron core and coils formed to wrap the iron core according to the present invention comprises: a cylinder-type insulator formed to contain the coils and to wrap an outer side of the iron core; an external vertical flow path formed between both sides of the coils and an inner wall of the cylinder-type insulator; a central vertical flow path formed vertically at a center part of the coils; a horizontal flow path horizontally formed between the coils; and a central flow path flow rate adjusting unit, provided on the central vertical flow path, for reducing a flow rate of the insulation oil passing through the central vertical flow path. |
