Zusammenfassung:The energy-saving cooling device comprises a dry-type transformer body, the two ends of the bottom of the dry-type transformer body are fixedly connected with U-shaped bottom frames, the bottoms of the U-shaped bottom frames are fixedly connected with a bottom plate, and the middle position of the top of the bottom plate is fixedly connected with an annular cooling frame. An annular groove is formed in the top of the annular cooling frame, a cold guide plate is fixedly connected to the inner wall of the annular groove, the cross section of the cold guide plate is of a U-shaped structure, and cooling liquid is injected into the annular cooling frame. The primary cooling performance is conveniently formed, a certain energy-saving effect is achieved, the range of cold air diffused in the annular cooling frame is enlarged through the first fan blades, the cold air makes full contact with the dry-type transformer body, the air circulation rate in the dry-type transformer body is increased through the second fan bl
