The invention relates to a high-frequency transformer with refrigeration function, and belongs to the technical field of general parts of transformers or inductors. The high-frequency transformer with the refrigeration function comprises a cooling pipe installed around the body of the transformer, and a separating plate is installed in the cooling pipe. The separating plate divides the cooling pipe into an inner channel and an outer channel. A first opening and a second opening are arranged in these separating plate, and the first opening is provided with a plurality of connecting rods and magnetic fluid boxes. The magnetic fluid boxes are installed on the inner side of the inner wall of the cooling pipe. The connecting rods are installed between the outer wall of the cooling pipe and the separating plate, and the connecting rods are connected to magnets in a sliding mode. Two sides of the cooling pipe are provided with a first pipeline and a second pipeline oppositely arranged and the first pipeline is connected to the cooling pipe in a sliding mode. A rotating blade is installed in the inner channel part of the outer wall of the first pipeline, and the inner channel is further provided with a first baffle which makes the rotating blade rotate in one direction. Fan blades are installed on the inner wall of the first pipeline. According to the technical scheme, the high-frequency transformer with the refrigeration function is skillfully designed and manufactured easily. The high frequency transformer is cooled and dissipated heats thorough ways of liquid absorption and air convection.
