Abstract
The invention discloses a heat exchanger with efficient nodal heat exchange tubes. The heat exchanger comprises an upper tube sheet, a housing, the nodal heat exchange tubes and lower tube sheet; the upper ends and the lower ends of the nodal heat exchange tubes are fixedly connected onto the upper tube sheet and the lower tube sheet respectively; the nodal heat exchange tubes comprises straight tube sections and wave tube sections; the wave tube sections are formed by a plurality of wave peaks and wave troughs through connection; the wave tube sections are separately arranged on the straight tube sections; the diameters of adjacent wave peaks of the wave tube sections are different from each other. The heat exchanger is characterized in that the wave tube sections arranged on the adjacent nodal heat exchange tubes are arranged in a staggered mode. According to the heat exchanger with the efficient nodal heat exchange tubes, the significant turbulence effect is generated through the significant change of the areas of through-flow sections in the tubes and accordingly the turbulent state of a medium, which can only be generated at the high velocity, can be generated at the low velocity and accordingly the heat exchange efficiency is significantly improved; the significant flushing effect can be generated and accordingly scales can be significantly reduced; the wave tube sections arranged on the adjacent nodal heat exchange tubes are arranged in a staggered mode and accordingly heat exchange of the integral heat exchanger can be uniform and the heat exchange efficiency can be significantly improved.
Description
Technical field
The present invention relates to a kind of heat exchanger, particularly a kind of wave node heat exchange tube heat exchanger.
Background technology
In recent years, wave node heat exchange tube heat exchanger had obtained development rapidly.Wave node heat exchange tube in existing wave node heat exchange tube heat exchanger comprises straight length, wave duct section, be all wave duct section substantially, and wave duct section is formed by connecting by isometrical crest, trough on whole wave node heat exchange tube.Although this wave node heat exchange tube heat exchanger can destroy the laminar condition that is unfavorable for heat transfer, be conducive to conduct heat, reduce incrustation, the turbulent effect forming is not remarkable, and heat exchange efficiency is not high, 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 exchange efficiency is high; Can produce obvious souring, significantly reduce the heat exchanger of the efficient wave node heat exchange tube of incrustation.
The present invention is achieved through the following technical solutions technical goal.
The heat exchanger of efficient wave node heat exchange tube, comprises upper perforated plate, housing, wave node heat exchange tube, lower perforated plate; Described wave node heat exchange tube upper and lower side is fixedly connected on respectively on upper perforated plate, lower perforated plate; Described 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, the wave duct section on adjacent wave node heat exchange tube is staggeredly arranged.
As the further 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 exchange efficiency; Wave node heat exchange tube reducing can produce obvious souring, significantly reduces incrustation.
2. the wave duct section on adjacent wave node heat exchange tube is staggeredly arranged, and not only can make whole heat exchanger heat exchange even, but also can significantly improve heat exchange efficiency.
3. each wave duct section adjacent peaks diameter successively decreases one by one, can further improve turbulent effect.
By above measure, the heat exchange efficiency of heat exchanger improves 15～20%.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the enlarged diagram of wave node heat exchange tube in Fig. 1.
Detailed description of the invention
The invention will be further described with reference to the accompanying drawings and in conjunction with the embodiments below.
The heat exchanger of efficient wave node heat exchange tube shown in the drawings, comprises upper perforated plate 1, housing 2, wave node heat exchange tube 3, lower perforated plate 4; Wave node heat exchange tube 3 upper and lower sides are fixedly connected on respectively on upper perforated plate 1, lower perforated plate 4; Wave node heat exchange tube 3 comprises straight length 3.1, wave duct section 3.2; Wave duct section 3.2 is formed by connecting by several crest 3.2.1, trough 3.2.2; Wave duct section 3.2 interval on straight length 3.1 is arranged; Each wave duct section 3.2 adjacent peaks 3.2.1 diameters are not identical, and in the present embodiment, each wave duct section 3.2 adjacent peaks 3.2.1 diameters successively decrease one by one.
In order to make whole heat exchanger heat exchange even, in the present embodiment, the wave duct section 3.2 on adjacent wave node heat exchange tube 3 is staggeredly arranged, and certainly so also can significantly improve heat exchange efficiency
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 exchange efficiency, and the heat exchange efficiency of heat exchanger improves 15～20%; And can produce obvious souring, significantly reduce incrustation.
