The invention relates to an intensified condenser tube, which belongs to the technical field of heat exchange parts. The intensified condenser tube comprises a tube body, outer fins and a main groove, wherein the outer fins are formed by materials on the tube body by expanding along the radius direction of the tube body and spirally extending around the tube body on the outer surface of the tube body and combined with the tube body as a whole, and the main groove is positioned between adjacent outer fins. The intensified condenser tube is characterized in that the top of the outer fins is provided with incisions in the separation state; one side of the outer fins is provided with first auxiliary grooves in the separation state in the same way; and the first auxiliary grooves extend downwards from the bottom of the incisions to the main groove. The intensified condenser tube has the advantages of improving the liquid drainage of condenser tubes to intensify condensation heat exchange.
