Description
Technical field
The utility model relates to the metal tube processing technique field, relate in particular to a kind of be used for heat transmission equipments such as heat exchanger revolve the arc heat exchanger tube.
Background technology
Heat exchanger tube is the critical component of heat transmission equipment, and the heat exchange efficiency of heat exchanger tube directly has influence on the operating efficiency of heat transmission equipment.Therefore, those skilled in the art is devoted to adopt diversified mode always, improves the heat exchange efficiency of heat exchanger tube.
As shown in Figure 1, CN201780028U discloses a kind of " spiral heat exchange tube ", the spiral heat exchange tube of described heat exchanger tube 1 for adopting the copper pipe brake forming to process, and the direction of 1 two connectors 2 of this heat exchanger tube is consistent with the axis direction of heat exchanger tube 1 bending and winding.This technical scheme is simple in structure, volume is little, the heat exchange property ratio is high, easy for installation, time saving and energy saving.But this warp architecture has just increased the length of heat exchanger tube in limited space, do not improve the heat exchange efficiency on the heat exchanger tube unit length, relatively is applicable to seamless straight collimator (for example gapless stainless steel tube etc.).As far as welded tube, this bending very easily destroys the firm degree of its commissure.
As shown in Figure 2, CN201867111U discloses a kind of " built-in reinforcement flow-disturbing chip heat exchanger tube ", and it has body 1; The center is furnished with spoiler along the axis total length in the body 1; Said spoiler has rectangular flat plate substrate 2, and punching out has the flow-disturbing petal 4 of a plurality of upper and lower staggered turnovers on the substrate, and the outer end of flow-disturbing petal 4 is arc surface or circular arc chamfering face; Its arc section face and body 1 fit tightly, and on flow-disturbing petal 4, have liquid flow hole 3.This technical scheme has heat exchange area and convection cell flow-disturbing in the enhanced tube, prevents the effect of spoiler vibration; Can improve the coefficient of heat transfer of heat exchanger tube, be mainly used in liquid heat-exchanger, the gas heat exchanger of industry high performance requirements such as petrochemical industry, boats and ships, metallurgy, naval vessels, electric power.But likewise, this heat exchange tube machining technique is complicated, and ties dirt easily and be difficult to remove.Especially, be not suitable for the straight less heat exchanger tube of pipe.
As shown in Figure 3, CN201811631U discloses a kind of " external tooth internally spiral heat-exchanging tube ", comprises body 1, rolling teeth 2 on the body 1 outer wall side face, the rolling helical fin 4 of said body 1 inwall; Said teeth 2 are elongated, its direction and body 1 parallel axes, and said teeth 2 cross sections are trapezoidal, form " V " font groove 3 between the adjacent teeth 2.This technical scheme has been improved the heat transfer property of pipe to a certain extent, and the setting of tube wall strip teeth has the effect of dredging, and the setting of inboard wall of tube body helical fin increases heat exchange area, the enhanced heat exchange effect.But this heat exchange tube machining technique is complicated, and is bigger to the raw material loss.
Above-mentioned various heat exchanger tubes of the prior art are when doing heat exchange, and heat transferring mediums such as water, oil, gas circulate in heat exchanger tube, by means of the technical purpose of heat-shift between other media that the heat exchange tube wall is realized and heat exchanger tube is outer.In heat exchanging process, more abundant near the heat exchange that heat transferring medium carried out in heat exchanger tube tube wall zone, heat exchange efficiency is higher; And away from the heat exchanger tube tube wall, be positioned at the heat exchange of heat transferring medium of heat exchanger tube central area and insufficient, though above-mentioned heat exchanger tube therefore of the prior art improves through certain, shortcoming is arranged respectively.
Therefore, those skilled in the art is devoted to develop a kind of simple in structure, easy to process, heat exchanger tube that heat exchange efficiency is high.
The utility model content
Because the above-mentioned defective of prior art, the utility model technical problem to be solved provide a kind of heat exchange efficiency high revolve the arc heat exchanger tube.
For realizing above-mentioned purpose, the utility model provides a kind of arc heat exchanger tube that revolves, and comprises body at least, and said body surrounds and forms a medium channel; Said body is a special-shaped pipeline section; Be formed with the groove that arc extends on the tube wall of said special-shaped pipeline section, the axis of said groove and said body forms a rotation angle; Said groove correspondingly is formed with protruding arc lines at the inwall of said body.
Preferably, said groove is one or more.
Preferably, the cross section of said groove is arc or triangle or isosceles trapezoid.
Preferably, said rotation angle is 1 ° to 75 °.
Preferably, the said relatively body of said groove is clockwise direction or counterclockwise extends.
Preferably, said body also comprises first straight length, second straight length that lays respectively at said special-shaped pipeline section two ends, and both and said special-shaped pipeline section are that one constitutes.
Preferably, said first straight length and said second straight length be not for isometric or isometric.
Preferably, said body is U-shaped or S shape.
Preferably, said body is circular oval or irregular oblateness.
Preferably, said body is welded tube or seamless steel pipe.
The utility model revolve the arc heat exchanger tube owing to adopted the special-shaped pipeline section of said structure design; The inwall of heat exchanging medium passage has the arc ripple, when heat transferring medium flows in medium channel, when rotating; Also receive the flow-disturbing influence of arc ripple; The flow-disturbing effect is obvious, thus heat transferring medium in pipe with manage outside heat exchange effect abundant, improved the heat exchanger effectiveness of body.
And, the body of said structure have the knot dirt less, clean to be easy to beneficial effect.
Owing to set up the first not isometric straight length, second straight length of integrative-structure at the two ends of special-shaped pipeline section, when making heat transmission equipment, be convenient to borrow and install, improved the assembling condition of heat transmission equipment.
Compare with straight collimator of the prior art, the medium channel in the straight collimator, slow at the part flow velocity near tube wall, fast near the part flow velocity at center, therefore, the temperature difference of medium channel different piece is big in the pipe, on inside pipe wall, forms dirt easily.And the heat exchanger tube of the utility model owing to be formed with eddy current in the pipe, is therefore managed having a narrow range of temperature of interior medium channel different piece, and fouling is relatively just few.
Compare with star heat exchanger tube of the prior art, though the star heat exchanger tube has shortened the core of medium channel and the distance between the tube wall, improved the heat exchanger effectiveness of core, each several part does not form eddy current each other in the star heat exchanger tube.And form eddy current between the each several part of the utility model in medium channel, improved the heat exchange efficiency of body.
Compare with the oval heat exchanger tube of spiral of the prior art,, formed flow-disturbing, improved heat exchange efficiency though the oval heat exchanger tube of spiral has the arc ripple equally at inwall.But the oval heat exchanger tube of existing spiral is to realize through straight body being reversed processing, receives bigger external force effect at the weld seam that reverses middle tube body.Though this external force does not surpass the tolerance range of body on intensity, but can damage the body especially intensity of weld seam parts to a certain extent.And the utility model revolve the arc heat exchanger tube in process engineering, body is not done and is reversed, therefore, weld seam part does not receive any external force effect, greatly firm its intensity.
Therefore, compare with various heat exchanger tubes of the prior art, the arc heat exchanger tube that revolves of the utility model all has significant beneficial effect.
