Structure-improved of the water-heater heat-exchanging water pipe with flow-disturbing spring, the structure is along heat exchanging water pipe axial direction in heat exchanging water pipe
Portion is provided with flow-disturbing spring, and the presence of the flow-disturbing spring causes current to be rotationally advancing in water pipe, to strengthen water pipe
The heat exchange efficiency of interior medium.But runner is generally divided into two by helical spring and single twisted strip structure, is unfavorable for temperature
The uniform of field is spent, and front face area causes greatly flow resistance excessive, causes heat exchanger combination property poor.In addition,
Pipe flow core space temperature is relatively low, easily causes the generation of bubble in heat transfer process under big temperature rise, low discharge operating mode
With extinction, noise problems of too is brought therewith.
The content of the invention
For problems of the prior art, the purpose of this utility model is to provide a kind of fluid to mix
Close that effect is good, and can effectively suppress bubble to produce to wither away and cause the heat exchanger tube of noise.
To reach object above, this utility model is adopted the following technical scheme that.
A kind of four twisted strip flow-disturbing heat exchanger tubes, including：Body and the twisted strip in body, its feature
It is that the quantity of the twisted strip is four, and four twisted strips are fitted together and are placed in body, and each twisted strip
Outside and body interior side contacts.
Used as with improvement, the two ends of twisted strip are fixed together by positioning annulus respectively.
As with improvement, draw-in groove is provided with the end of twisted strip, the positioning annulus is connected in draw-in groove will
Four twisted strips are fitted together.
Used as with improvement, the draw-in groove is arranged on the center position of twisted strip end.
Used as with improvement, each twisted strip is uniformly distributed along positioning annulus, is pressed from both sides in 90 ° between adjacent two twisted strip
Angle.
As with improvement, four draw-in grooves are provided with positioning annulus, the end of each twisted strip is connected to respectively
In corresponding draw-in groove.
Used as with improvement, four draw-in grooves are uniformly distributed along positioning annulus.
The beneficial effects of the utility model are：Propose a kind of brand-new flow-disturbing mode --- four twisted strip structures
Heat exchanger tube, designs a kind of heat exchanger tube being evenly arranged by four twisted strips.The structure can be in pipe inner core region
Four longitudinal Vortexes are formed, boundary layer fluid have effectively been disturbed, has been made the eddy flow of tube fluid become more complicated,
Strengthen the mixing of fluid, the temperature field in pipe inner core region is more uniformly distributed, therefore is thinned wall boundary region,
Enhance heat exchange, pipe flow cross-section temperature field uniformly effectively to suppress bubble to produce the noise for causing of withering away excessive,
The fin effect of twisted strip can also play the effect for strengthening heat exchange simultaneously.

Specific embodiment
Essence of the present utility model is more fully understood for convenience of those skilled in the art, below in conjunction with the accompanying drawings
Specific embodiment of the present utility model is described in detail.
As shown in Figure 1-Figure 3, a kind of four twisted strips flow-disturbing heat exchanger tube, including：Body 1 and be arranged on body 1
Interior twisted strip 2, it is characterised in that the quantity of the twisted strip 2 is four, and four twisted strips 2 fit together placement
To in body 1, and the outside of each twisted strip 2 and body interior side contacts.
Wherein, the two ends of each twisted strip 2 are fixed together by positioning annulus 3 respectively.In the end of twisted strip 2
Center position be provided with draw-in groove 2-1, the positioning annulus 3 is connected in draw-in groove 2-1, each twisted strip 2 along positioning annulus
3 are uniformly distributed, and are in 90 ° of angles between adjacent two twisted strip 2.
The four twisted strip flow-disturbing heat exchanger tube of one kind that the present embodiment is provided, by single twisted strip end centre bit
Put out draw-in groove, by the small circle ring of positioning (toroid size Jing is accurate to be calculated, it is ensured that overall twisted strip structure and
Heat exchanger tube is fitted close) be put into, four twisted strips are in 90 ° to be uniformly distributed, after be welded and fixed, then will be four twisted strips whole
Body structure is put in heat exchanger tube.The structure is fitted close with pipeline, is easily positioned, it is easy to accomplish.It is comprehensive
Ensure pipe inner core region uniform temperature fields while being lifted, be effectively reduced bubble formation and generation of withering away
Noise.
Normally, in heat exchanger tube, the mode of enhanced heat exchange mainly has based on surface peening and based on fluid zone
Two classes are strengthened in domain, and the four twisted strip heat exchanger tubes that the present embodiment is proposed are the comprehensive uses of two class enhanced heat transfer modes,
Twisted strip and the flow boundary layer not only disturbed near wall that is engaged in tube wall face, the longitudinal direction for being formed
Whirlpool also effectively makes the mixing of core space fluid more uniform.The separation of velocity boundary layer and temperature boundary layer is more
Be conducive to heat exchange.Analyze from field-synergy theory, the velocity vector field of the structure and temperature gradient vector field
Angle is less, and preferably, energy transport is good with momentum-transport orientation consistency, heat-energy transducer for the collaboration degree of two
Power is strong.Find through numerical computations, the lifting of three twisted strip structures exchange hot property is little, although its resistance is not
Greatly；The perturbation action of five twisted strip structure convection cells is fine, but resistance increases excessive.Three twisted strip of overall merit is tied
It is poor with four twisted strip structures that structure and five twisted strip structure composition performances are compared.
Embodiment two
The four twisted strip flow-disturbing heat exchanger tube of one kind that the present embodiment is provided, its structure are basically identical with embodiment one,
Difference is：Draw-in groove is not provided with twisted strip end, and is changed to four draw-in grooves are provided with positioning annulus, four
Draw-in groove is uniformly distributed along positioning annulus, and the end of each twisted strip is connected in corresponding draw-in groove respectively.
Above specific embodiment has been described in detail to essence of the present utility model, but can not be with
This is limiting to protection domain of the present utility model.It should be evident that opening in this utility model essence
Under showing, the art those of ordinary skill can also carry out many improvement and modification, it should be noted that this
It is a little to improve and modify all to fall within claims of the present utility model.
