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 cross ellipse tube different with conventional heat transfer reinforced pipe
Section and disc heat exchange reinforced pipe.Passed with the angle raiser for cooperateing with of temperature gradient field from fluid velocity
Enhanced new method " field coordination principle " is passed, that is, improves the collaborative e-commerce of field, just can increase less bar in resistance
Strengthen heat transfer under part.The present invention, according to this principle, is that Guan Liuzhong can form Radial Flow, just can significantly be changed
It is apt to the degree that cooperates with of velocity field and temperature gradient field, and then strengthens heat transfer, while has also 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 a kind of cross ellipse tube section and disc heat exchange reinforced pipe,
Including pipe section, pipe section is connected by oval changeover portion with oval pipeline section.Each pipe section is isometric；It is each ellipse
Pipe section is isometric；The section transverse A intersecting angles C of two adjacent oval pipeline sections is 60 °~90 °；It is ellipse
The shape of cross section of circle transitional tubing piece adds what two circular arcs were constituted for standard ellipse or sub-elliptical or two straight lines
The oblate or circle of the symmetrical and near symmetrical of oblate or multistage camber line fitting；Each oval transitional pipe segment
It is long.The two ends of the cross ellipse tube section and disc heat exchange reinforced pipe set Conduit Joint section；Conduit Joint section
Inner wall smooth；Conduit Joint section is identical with the internal diameter d of pipe section, pipe section and ellipse pipeline section cycle successively
Connected by oval changeover portion in the middle of arrangement.
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 1.3~1.7.
Preferably, the inner surface and appearance of the pipe section, the oval pipeline section and the oval transitional pipe segment
Face is thread 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 cross ellipse tube section and disc heat exchange reinforced pipe, including pipe section 1；
Pipe section 1 is connected by oval changeover portion 3 with oval pipeline section 2；Each pipe section 1 can be isometric or not
Isometric；Each oval pipeline section 2 can be equal or different length.Two sections of adjacent oval pipeline section 2
Transverse A intersecting angles C is 60 °~90 °, and this angle is produced more to increase when liquid in pipe flows
Big resistance.The shape of cross section of oval transitional pipe segment 3 is that standard ellipse or sub-elliptical or two straight lines add
Two oblate or circles of the symmetrical and near symmetrical of the oblate or multistage camber line fitting of circular arc composition；It is each ellipse
Circle transitional pipe segment 3 can be equal or different length.The cross ellipse tube section and disc heat exchange reinforced pipe
Two ends set Conduit Joint section 4；The inner wall smooth of the Conduit Joint section 4, the smooth inwall is to pacify
Can be with better seal during dress；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 1.3~1.7.
Pipe section 1, the inner surface of oval pipeline section 2 and oval transitional pipe segment 3 and outer surface are thread surface,
Such pipeline increased the contact surface of heat transfer, increase heat exchanger effectiveness.Fig. 3 is liquid in oval pipeline section
The distributed architecture schematic diagram of body 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.
