Description

A kind of poor double pipe heat exchanger of small end and its component
Technical field
The utility model is related to field of heat exchangers, the high efficiency sleeve type heat exchanger and its group of more particularly to a kind of small end difference Part.
Background technology
Heat exchanger is also known as heat exchanger, using widely.Heat exchanger species is a lot, and wherein double pipe heat exchanger has knot Structure is simple, heat transfer coefficient is big, using facilitating the features such as, important position is occupied in the application of heat exchanger.
Existing double pipe heat exchanger technology sets various complicated to improve heat exchange efficiency between inner tube, outer tube Structure, causes processing and manufacturing difficult, and processing cost is too high, hinders promotion and application.
Such as the patent ZL200410012672.0 of entitled " efficient capillary spiral finned tube ", although welded on inner tube is cylindrical Helical fin is connected to, but is due to that inner tube inner circle is light pipe, heat exchange efficiency is not high.
Such as the patent ZL201020590118.1 of entitled " coaxial spiral tubes heat exchanger ", although it is on inner tube is cylindrical Special tooth form is machined with, but on the one hand the tooth form is difficult to process, and causes processing difficulties, it is with high costs, on the other hand, inner tube Inner circle is light pipe, is still difficult to the heat exchange efficiency for lifting heat exchanger.
Utility model content
For defect present in prior art and deficiency, the purpose of this utility model be to provide it is a kind of it is simple in construction, The poor high efficiency sleeve type heat exchanger of the small end of simple processing and its component.
The technical solution of the utility model is as follows:
A kind of poor double pipe heat exchanger of small end, including outer tube and inner tube, said inner tube is coaxially disposed in outer tube, described Inner tube it is cylindrical on be provided with fin, it is characterised in that:The inner headed face of said inner tube is provided with groove.
Optionally, the groove curl is arranged on inner tube inner headed face.
Optionally, the groove is some, and is distributed on inner tube inner headed face.
Optionally, the trench cross-section is rectangle, trapezoidal or semicircle.
Optionally, one end of the outer tube is provided with water inlet, and the other end is provided with delivery port.
Optionally, the water inlet and delivery port are located in the both sides of outer tube excircle, and outer tube and flowed in flow direction and inner tube To contrary.
Optionally, the fin is one group of straight longitudinal fin being distributed on inner tube excircle or the radial direction set into spiral There is a gap between fin, and the top of fin and outer tube inner headed face.
A kind of poor casing type heat exchanging device assembly of small end, it is characterised in that:Described sleeve pipe formula heat exchanger includes two or two Double pipe heat exchanger as described above above, each double pipe heat exchanger combines connection in series or in parallel.
It is of the present utility model to have technical effect that:
Double pipe heat exchanger of the present utility model uses the inner tube with internal channel, compared with existing light-pipe structure, one Aspect, interior tube fluid is turbulent condition, is conducive to the exchange of heat, improves heat exchanger effectiveness, on the other hand, spiral groove Structure combination inner tube itself expand with heat and contract with cold, be conducive to the fouling voluntarily avalanche of inner tube, improve bushing type of the present utility model The antiscaling effect of heat exchanger.
In addition, being additionally provided with fin between the inner and outer tubes of double pipe heat exchanger of the present utility model, fin is using straight It is vertical that there is a gap between fin or spiral radial fins, and the top of fin and outer tube inner headed face, it is easy to process, into This is low, and resistance suffered by the fluid between pipe is small, and can further improve improves the heat exchanger effectiveness of heat exchanger.
Brief description of the drawings
Fig. 1 show structural representation of the present utility model.
Fig. 2 show the Longitudinal cross section schematic of the inner tube of the utility model double pipe heat exchanger.
Fig. 3 show the schematic diagram of one heat exchanger unit of the utility model.
Fig. 4 show the schematic diagram for the heat exchanger group being used in series.
Fig. 5 show the schematic diagram of heat exchanger group used in parallel.
Embodiment
The utility model is described further below in conjunction with accompanying drawing.
It is structural representation of the present utility model as shown in Figure 1.Including outer tube 1 and inner tube 2, inner tube 2 with outer tube 1 is coaxial sets Put.
The inner headed face of inner tube 2 is provided with some grooves 4, and the cross section of groove 4 is rectangular configuration, can also select trapezoidal or half Circular configuration, each groove 4 is equidistantly distributed on inner headed face.
The groove structure set as shown in Figure 2 using spiral as preferred embodiment, groove 4, with straight flute slot structure phase Than this frame mode is conducive to fluid in inner tube 2 to produce turbulent flow, accelerates the heat transfer of tube fluid, improves heat exchange efficiency.
And this groove structure and the phenomenon combination of expanding with heat and contract with cold of inner tube 2 itself, in-tube fouling can be promoted certainly Row avalanche, with certain antiscaling effect.
The periphery of inner tube 2 is provided with fin 3, between the top of fin 3 and cylindrical 1 inner headed face have one it is less between Gap, to ensure the mobile performance of fluid between pipe.
Fin 3 can be directly vertical fin, it would however also be possible to employ spiral radial fins.
The two ends of outer tube 1 set water inlet 5 and delivery port 6 respectively, and water inlet 5 and delivery port 6 are respectively arranged at outer tube 1 The both sides of excircle.Fluid flows to contrary in the flow direction of fluid and inner tube 2 in outer tube 1, as shown in Figure 3.
Double pipe heat exchanger of the present utility model can be used with monomer, can also be applied in combination.
It is illustrated in figure 4 the schematic diagram that double pipe heat exchanger of the present utility model uses series system to be applied in combination.As A kind of embodiment, two heat exchanger monomers join end to end, and medium 1 flows through the inner tube 2 of two heat exchanger monomers successively.
It is illustrated in figure 5 the schematic diagram that double pipe heat exchanger of the present utility model uses parallel way to be applied in combination.
As a kind of embodiment, two heat exchanger monomer parallel connections, medium 1 flows separately through two heat exchanger lists after shunting The inner tube 2 of body.
In both examples above, using 2 heat exchanger combination of monomers as an example, for the utility model, its Combination is not limited solely to the series, parallel combination of 2 heat exchanger monomers, is also not limited to simple serial or parallel connection side Formula, can also be used according to being actually needed using series connection and parallel combination.
