Abstract

The utility model discloses a variable-diameter wave node heat exchange pipe which comprises a straight pipe section and wave pipe sections. Each wave pipe section is formed by connecting multiple wave crests and wave valleys, the wave pipe sections are arranged on the straight pipe section at intervals, and diameters of adjacent wave crests of each wave pipe section are different. Remarkable turbulence effect is generated through notable changes of the area of a passage section in the pipe, so that turbulence states which can be generated only at high flowing speed can be generated at low flowing speed of media, and heat transfer effect is substantially improved; and obvious scouring effect can also be generated, scaling can be remarkably reduced, and the variable-diameter wave node heat exchange pipe is suitable for heat exchangers of various specifications.

Description

Reducing node heat exchanger tube
Technical field
The utility model relates to a kind of heat exchange element, particularly a kind of heat exchanger node heat exchanger tube.
Background technology
The tradition heat exchanger tube is straight tube, and in recent years, the node heat exchanger tube had obtained development rapidly.Existing node heat exchanger tube comprises straight length, wave duct section, the wave duct section is formed by connecting by several crests, trough, though can destroying, this node heat exchanger tube is unfavorable for the laminar condition that conducts heat, be conducive to conduct heat, reduce incrustation, but owing to all be the wave duct section basically on the whole node heat exchanger tube, and the wave duct section is formed by connecting by isometrical crest, trough, therefore formed turbulent effect is bad, and the effect that reduces incrustation is also bad.
The utility model content
The utility model proposes a kind of energy and forms significant turbulent effect at the deficiencies in the prior art, and heat-transfer effect is good; Can produce tangible souring, significantly reduce the reducing node heat exchanger tube of incrustation.
The utility model is achieved through the following technical solutions technical goal.
Reducing node heat exchanger 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 is arranged on straight length at interval; Each described wave duct section adjacent peaks diameter is inequality.
As the preferred version of such scheme, each described wave duct section adjacent peaks diameter successively decreases one by one.
The utility model compared with prior art has following good effect:
1. the wave duct section is arranged on straight length at interval, each wave duct section adjacent peaks diameter is inequality, marked change by passage section area in managing, produce significant turbulent effect, make medium under low flow velocity, just can produce the turbulent condition that could produce than high flow velocities, significantly improve heat-transfer effect.
2. each wave duct section adjacent peaks diameter successively decreases one by one, can further improve turbulent effect.
3. node heat exchanger tube reducing can produce tangible souring, significantly reduces incrustation.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments below.
Reducing node heat exchanger 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 is arranged on straight length 1 at interval; Each wave duct section 2 adjacent peaks 2.1 diameter is inequality, and in the present embodiment, each wave duct section 2 adjacent peaks 2.1 diameter successively decreases one by one.
The utility model produces significant turbulent effect by the marked change of passage section area in the pipe, 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 tangible souring, significantly reduce incrustation.
