The invention discloses a pyramid-shaped finned condensing tube, comprising a tube body with an inner cavity, wherein a plurality of independent fins are arranged on the outer surface of the tube body; and the pyramid-shaped finned condensing tube is characterized in that the fins are peripherally twisted around the central axis in a height direction to be pyramid-shaped, and the plurality of fins are regularly arrayed along the axis of the tube body. The asymmetric finned condensing tube disclosed by the invention solves the shortages of the conventional condensing tube, and can drain liquid fast from a condensing heat exchange tube and effectively enlarges a heat exchange area, thus achieving a beneficial effect of high heat exchange efficiency.
