Abstract
The invention discloses a diameter-changing wave node heat exchange tube which comprises a direct tube section and wave tube sections. The wave tube sections are formed by connecting a plurality of crests and troughs and are arranged on the direct tube section at intervals, and the diameters of the adjacent crests of each wave tube section are different. The remarkable turbulence effect is generated through the remarkable changes of the area of the passage section inside the tube, under a low flow velocity a medium can generate a turbulence state which can be generated only under a high flow velocity, and the heat transfer effect is improved obviously; the obvious scouring effect can be generated, scale is obviously reduced, and the heat exchange tube is suitable for heat exchangers of various specifications.
Description
Technical field
The present invention relates to a kind of heat exchange element, particularly a kind of heat exchanger wave node heat exchange tube.
Background technology
Tradition heat exchanger tube is straight tube, and in recent years, wave node heat exchange tube had obtained development rapidly.Existing wave node heat exchange tube comprises straight length, wave duct section, wave duct section is formed by connecting by several crests, trough, although this wave node heat exchange tube can destroy the laminar condition that is unfavorable for heat transfer, be conducive to conduct heat, reduce incrustation, but owing to being all wave duct section substantially on whole wave node heat exchange tube, and wave duct section is formed by connecting by isometrical crest, trough, therefore the turbulent effect that formed is bad, and the effect that reduces incrustation is also bad.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose one and can form significant turbulent effect, heat-transfer effect is good; Can produce obvious souring, significantly reduce the reducing wave node heat exchange tube of incrustation.
The present invention is achieved through the following technical solutions technical goal.
Reducing wave node heat exchange tube, comprises straight length, wave duct section; Described wave duct section is formed by connecting by several crests, trough; Its improvements are: described wave duct section interval on straight length is arranged; Each described wave duct section adjacent peaks diameter is not identical.
As the preferred version of such scheme, each described wave duct section adjacent peaks diameter successively decreases one by one.
The present invention compared with prior art, has following good effect:
1. wave duct section interval on straight length is arranged, each wave duct section adjacent peaks diameter is not identical, by managing the marked change of interior passage section area, produces significant turbulent effect, make medium just can produce the turbulent condition that could produce than high flow velocities under low flow velocity, significantly improve heat-transfer effect.
2. each wave duct section adjacent peaks diameter successively decreases one by one, can further improve turbulent effect.
3. wave node heat exchange tube reducing can produce obvious souring, significantly reduces incrustation.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
The invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments below.
Reducing wave node heat exchange tube shown in the drawings, comprises straight length 1, wave duct section 2; Wave duct section 2 is formed by connecting by several crests 2.1, trough 2.2; Wave duct section 2 interval on straight length 1 is arranged; Each wave duct section 2 adjacent peaks 2.1 diameters are not identical, and in the present embodiment, each wave duct section 2 adjacent peaks 2.1 diameters successively decrease one by one.
The present invention, by the marked change of passage section area in pipe, produces significant turbulent effect, makes medium just can produce the turbulent condition that could produce than high flow velocities under low flow velocity, significantly improves heat-transfer effect; And can produce obvious souring, significantly reduce incrustation.
Claims (2)
1. a reducing wave node heat exchange tube, comprises straight length (1), wave duct section (2); Described wave duct section (2) is formed by connecting by several crests (2.1), trough (2.2); It is characterized in that: described wave duct section (2) is arranged at the upper interval of straight length (1); Each described wave duct section (2) adjacent peaks (2.1) diameter is not identical.
