Abstract
The invention provides an arch static turbulent element in a heat exchange pipe, which comprises a hollow shaft and a disk, wherein the disk is an arch protruding rib on the hollow shaft; the outer diameter of the disk is larger than that of the hollow shaft; a heat exchange device applied by the turbulent element comprises a heat exchange pipe, turbulent elements, hanging elements and a support shaft; a plurality of turbulent elements penetrate through the support shaft; and the support shaft is fixed by hanging elements at both ends of the heat exchange pipe. In the technical scheme, when fluid in the heat exchange pipe passes through the turbulent elements, the outer diameter of the hollow shaft at the front end is smaller; when the fluid flows through the arch surface of the disk, the sectional area through which the fluid can flow is reduced; the fluid flows out of a clearance between the outer edge of the disk and the inner surface of the heat exchange pipe; the higher the speed of the fluid is, the larger the mixing degree of the fluid is, and the larger the scouring force on the inner wall of the heat exchange pipe is, thereby being beneficial to preventing and removing scales; and the speed fluctuation of the fluid is larger, and turbulivity is improved, therefore, the reinforced heat transfer effect of the fluid is improved.
