Description

A kind of new heat exchange enhancing radiator

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 a kind of new heat exchange enhancing radiator, including heat exchange Pipeline, the heat exchanging pipe includes pipe section, and pipe section is connected by oval changeover portion with oval pipeline section. Each pipe section is isometric；Each oval pipeline section is isometric；The section transverse A of two adjacent oval pipeline sections intersects Angle C is 15 °~90 °；The shape of cross section of oval transitional tubing piece is that standard ellipse or sub-elliptical or two are straight Line adds two oblate or circles of the symmetrical and near symmetrical of the oblate or multistage camber line fitting of circular arcs composition； Each oval transitional pipe segment is isometric.The two ends of the heat exchanging pipe are provided with Conduit Joint section；Conduit Joint section Inner wall smooth；Conduit Joint section is identical with the internal diameter d of pipe section, and the cycle arranges successively for pipe section and oval pipeline section Connected by oval changeover portion in the middle of row.

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 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.

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 new heat exchange enhancing radiator, including heat exchanging pipe 5, the heat Exchanging pipeline 5 includes pipe section 1；Pipe section 1 is connected by oval changeover portion 3 with oval pipeline section 2；Respectively Pipe section 1 can be equal or different length；Each oval pipeline section 2 can be equal or different length.Two The section transverse A intersecting angles C of adjacent oval pipeline section 2 is 15 °~90 °, and this angle is to increase Plus produce bigger resistance during liquid flowing in pipe.The shape of cross section of oval transitional pipe segment 3 is standard ellipse Or sub-elliptical or two straight lines add the symmetrical and approximate of oblateness that two circular arcs constitute or the fitting of multistage camber line Symmetrical oblate or circle；Each oval transitional pipe segment 3 can be equal or different length.The heat exchanging pipe 5 Two ends set Conduit Joint section 4；The inner wall smooth of Conduit Joint section 4, the smooth inwall be in order to Can be with better seal during installation；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 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.
