Description
Technical field
The present invention relates to a kind of heat-transfer arrangement, more particularly to a kind of heat-exchange device of duct type.
Background technology
Heat transfer enhancing technology can also reach the purpose of energy-conservation because heat transfer speed can be improved, in daily life
It is widely used in work.Heat transfer enhancing technology is broadly divided into actively enhancing and passive enhancing technology.Before
Person refers to need the heat transfer enhancing technology from extraneous input energy, such as electric-field enhancing, magnetic field-enhanced, vibration
Enhancing technology etc.；The latter refers to the heat transfer enhancing technology for not needing outside energy, therefore is easier to be answered
Use in the middle of engineering.Passive enhancing technology generally includes extended surface (fin), that pipe is inserted into thing, eddy flow is (disorderly
Stream) generator etc..Passive enhancing technology has been widely used, but there are still a common problem,
While i.e. heat transfer strengthens, flow resistance increases more, is unfavorable for energy-conservation, so as to hinder these technologies
It is applied more broadly in each engineering field.
Therefore those skilled in the art endeavour and develop a kind of Novel hot friendship different with conventional heat transfer reinforced pipe
Change pipe.From fluid velocity enhanced new method " field is transmitted with the angle raiser for cooperateing with of temperature gradient field
Collaboration principle ", that is, improve the collaborative e-commerce of field, just can strengthen heat transfer under conditions of resistance increase is less.This hair
Bright is that Guan Liuzhong can form Radial Flow according to this principle, can just significantly improve velocity field and thermograde
The collaboration degree of field, and then strengthen heat transfer, while also having reached the effect of energy-conservation.
The content of the invention
In view of the drawbacks described above of prior art, the technical problems to be solved by the invention are to provide a kind of heat transfer
Efficiency high, simple structure, the heat-exchange tube of energy-conserving and environment-protective.
To achieve the above object, the invention provides one kind improvement heat exchange enhancing water heater, its heat power supply device
Including heat exchanging pipe, the heat exchanging pipe includes pipe section, and pipe section is by oval changeover portion and ellipse
Pipeline section is connected.Each pipe section is isometric；Each oval pipeline section is isometric；Two sections of adjacent oval pipeline section are oval
Major axis A intersecting angle C is 15 °~90 °；The shape of cross section of oval transitional tubing piece is standard ellipse or approximate ellipse
Circle or two straight lines add the flat of the symmetrical and near symmetrical of the oblateness that two circular arcs constitute or the fitting of multistage camber line
Circular or circle；Each oval transitional pipe segment is isometric.The two ends of the heat exchanging pipe are provided with Conduit Joint section；Circle
The inner wall smooth of pipe joint section；Conduit Joint section with pipe section internal diameter d it is identical, pipe section and ellipse pipeline section
Connected by oval changeover portion in the middle of periodic arrangement successively.
Preferably, the ratio of the length Lc and its internal diameter d of the pipe section is 0.5~10；The oval pipeline section
Length Le and the pipe section internal diameter d ratio be 1~10；The major axis of the oval transitional pipe segment external diameter
The ratio of A and short axle B is 1.1~2.5.
Preferably, the inner surface and appearance of the pipe section, the oval pipeline section and the oval transitional pipe segment
Face is smooth surface.
The beneficial effects of the invention are as follows：Simple structure of the present invention, effective and reasonable has coordinated velocity field and temperature
The balance of gradient fields, energy-conserving and environment-protective efficiency high.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Fig. 2 is elliptical tube segment length between centers angle schematic diagram of the invention.
Fig. 3 is the liquid flowing state schematic diagram in ellipse pipeline section of the invention.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples：
As shown in Figure 1 and Figure 2, a kind of improvement heat exchange enhancing water heater, its heat power supply device includes heat-exchange tube
Road 5, the heat exchanging pipe 5 includes pipe section 1；Pipe section 1 is by oval changeover portion 3 and oval pipeline section
2 connections；Each pipe section 1 can be equal or different length；Each oval pipeline section 2 can be equal or different length
's.The section transverse A intersecting angles C of two adjacent oval pipeline sections 2 is 15 °~90 °, this angle
It is to produce bigger resistance to increase when liquid in pipe flows.The shape of cross section of oval transitional pipe segment 3 is
Oblateness that standard ellipse or sub-elliptical or two straight lines add two circular arcs to constitute or the fitting of multistage camber line it is right
Claim or circle oblate near symmetrical；Each oval transitional pipe segment 3 can be equal or different length.The heat
The two ends for exchanging pipeline 5 set Conduit Joint section 4；The inner wall smooth of the Conduit Joint section 4, this is smooth
Inwall can be with better seal when being to install；Conduit Joint section 4 is identical with the internal diameter of pipe section 1.
The ratio of the length Lc and its internal diameter d of pipe section 1 is 0.5~10；The length Le of oval pipeline section 2 with
The ratio of the internal diameter d of pipe section 1 is 1~10；The major axis A and short axle B of the external diameter of oval transitional pipe segment 3
Ratio be 1.1~2.5.
Pipe section 1, the inner surface of oval pipeline section 2 and oval transitional pipe segment 3 and outer surface are smooth surface,
Such pipeline reduces the resistance of liquid flowing, reduces energy ezpenditure.Fig. 3 is liquid in oval pipeline section
The distributed architecture schematic diagram of flowing.
Preferred embodiment of the invention described in detail above.It should be appreciated that the ordinary skill of this area
Personnel just can make many modifications and variations without creative work with design of the invention.Therefore, it is all
Technical staff passes through logic analysis, pushes away on the basis of existing technology under this invention's idea in the art
Reason or the available technical scheme of limited experiment, all should be in the protection model being defined in the patent claims
In enclosing.
