The invention provides a novel coaxial cross twisted tape and a heat transfer enhancing tube using the same. The twisted tape is composed of multiple novel coaxial cross twisted tape sections, an outer pipe, fixing devices and connecting devices and is characterized in that the multiple novel coaxial cross twisted tape sections are composed of two to four twisted tape sections with the same width, thickness and torsional curvature; the width of the twisted tape sections is slightly smaller than the diameter of the outer pipe, the thickness of the twisted tape sections is 0.0-0.1 time the diameter of the outer pipe, the torsional curvature range is 1.0-6.0, and the included angles between all the twisted tape sections are equal; the edges of the twisted tape sections can be smooth and can also be in a sawtooth shape, or vortex generators can be additionally arranged on the surfaces of the twisted tape sections; according to the placement mode, the single twisted tape section can be placed with the length being slightly smaller than that of the outer pipe; and the multiple twisted tape sections can be placed at intervals, the interval between every two adjacent sections is 1.0-4.0 times the pitch, and then the multiple twisted tape sections are connected through the connecting devices; or the latter section and the former section are staggered by a certain angle and then connected through the connecting devices. According to the twisted tape and the heat transfer enhancing tube using the same, the heat transfer enhancing effect is good, mounting is convenient, the comprehensive heat transfer performance is high, and the high practicability is achieved.
