Abstract

The present invention relates to a separate type radiator for transformer which cools down by making insulating oil flow by being combined with an upper or lower side of the main body of a transformer. The separate type radiator for transformer includes: an inlet pipe which the insulating oil flows in; an outlet pipe which the insulating oil flows out and is symmetrically positioned to form a horizontal shape with the inlet pipe; multiple radiating pipes which are combined to be extended from the inlet pipe at one end part by being positioned between the inlet pipe and the outlet pipe and are combined to be extended from the outlet pipe at the other end part; and a flow control valve which is positioned in the inlet path of the inlet pipe. The insulating oil is efficiently cooled down because the quantity of the insulating oil which flows in the separate type radiator for transformer can be controlled and evenly distributed by using the flow control valve.
