The invention provides a novel alternately-spiral heat exchange pipe with internal ribs warping. The novel alternately-spiral heat exchange pipe is composed of a clockwise spiral warping section, a straight pipe section, an anticlockwise spiral warping section and the ribs, and the ribs are distributed on the inner pipe wall and warp periodically. Working media of the novel alternately-spiral heat exchange pipe have the advantages of being high in turbulent extent, large in heat exchange coefficient and not prone to scaling when flowing in the pipe for heat exchange, and the pipe has high actual application value.

Description

A kind of Novel interphase spiral internal-rib torsion heat exchange pipe
Technical field
The present invention relates to a kind of Novel interphase spiral internal-rib torsion heat exchange pipe, belong to enhanced heat exchange technical field.
Background technology
Heat exchanger has a wide range of applications in all trades and professions of national economy, one of modal equipment in the energy, oil, chemical industry, metallurgy, power, light industry, food and even Aero-Space industry, it is exploitation secondary energy sources, realizes the visual plant that recuperation of heat economize energy dissipates; At present, shell-and-tube heat exchanger is widely used because its flow is large, droop loss is little and operating pressure is high; The heat exchanger tube of the shell-and-tube heat exchanger in engineer applied all uses light pipe, and the turbulence effects of working fluid in light pipe is poor, causes heat transfer effect not obvious, the shortcoming that heat exchange efficiency is not high; The shell-and-tube heat exchanger general cycle of operation is longer, and in fluid, the dirt deposition such as impurity, easily blocks, affect the efficiency of equipment, the heat exchange pipeline fouling of especially large-scale shell-and-tube heat exchanger, can form blocking, this not only affects heat transfer effect, and affects the operation of whole technological process.
Summary of the invention
For the above problem, the invention provides a kind of Novel interphase spiral internal-rib torsion heat exchange pipe, its advantage is, when Bottomhole pressure heat exchange, turbulent extent is high, the coefficient of heat transfer is high for working media, less scaling.
The Novel interphase spiral internal-rib torsion heat exchange pipe that the present invention relates to is made up of inducer [1], clock wise spirals distortion section [2], straight length 1 [3], counter-clockwise helical distortion section [4], straight length 2 [5], outlet section [6], inducer internal-rib [7], clock wise spirals distortion section internal-rib [8], straight length 1 internal-rib [9], counter-clockwise helical distortion section internal-rib [10], straight length 2 internal-rib [11], outlet section internal-rib [12]; The internal-rib pattern of this type Novel interphase spiral internal-rib torsion heat exchange pipe has 3 kinds of patterns such as trapezoidal, square and triangle, the structural parameters that the geometric parameter of its various types is are: (1) is trapezoidal to be formed primarily of rib height A [31], oblique angle A1 [33], oblique angle A2 [34] and rib top width A [32], (2) square primarily of rib height B [35] and rib top width B [36] composition, (3) triangle forms primarily of rib height C [37], oblique angle C1 [38] and oblique angle C2 [39]; The destruction that the exception that the structure of this Novel interphase spiral internal-rib torsion heat exchange pipe produces in the wall boundary layer that wall is formed and schmutzband fluid is strong, makes the coefficient of heat transfer improve; The cross section basic circle of this Novel interphase spiral internal-rib torsion heat exchange pipe is oval, and the major axis [21] of its pipe thickness [23], basic circle and the minor axis [22] of basic circle can produce different sizes according to the geometric parameter of fin; This Novel interphase spiral internal-rib torsion heat exchange pipe has that turbulent extent is high, the coefficient of heat transfer is high and the advantage such as less scaling, and engineer applied has good development prospect and actual application value widely.
