Corrugated radiator

The utility model discloses a corrugated radiator for transformer, which is applied to an electric power system. The corrugated radiator mainly comprises a corrugated pipe, oil guide pipes and an air exhaust system. The corrugated radiator is structurally characterized in that an air exhaust device and an oil guide pipeline are arranged on a radiating body by a metal corrugation radiation technology to form a sealed oil path circulating system. The corrugated radiator has the characteristics of small size, light weight, a few welding seams and large radiating area, so that a transformer is cooled efficiently and safely; and air cooler and water cooler, which are widely used at present, can be replaced. The working principle of the corrugated radiator is as follows: high-temperature insulated oil of a transformer flows into the corrugated radiating body through an upper oil guide pipe when the system operates, is radiated by two corrugated surfaces and then flows back to a transformer oil tank from a lower oil
