Description
Technical field
This utility model is related to radiating tube technical field, and specifically bimetal composite exempts to cut painting one-shot forming radiating
Pipe.
Background technology
At present, finned tube is wide in numerous industries such as petrochemical industry, ship, automobile, papermaking, refrigeration as heat exchange, heat dissipation element
General application.The form of existing finned tube mostly is nest plate type and spiral winding chip.Nest plate type mostly is machinery suit, and its noise is big, surely
Qualitative and poor stability；Equipment price is more expensive, higher to the technical requirements of use and maintenance personnel and productivity ratio is low.Around chip be by
The foil of long with shape, good heat conductivity using the method for winding, embedded method, fold embedded method and welding
Method links together with metal tube, forms spiral-shaped finned tube.It is improved by increasing the contact area of conduction of heat
Heat exchanger effectiveness.The gap of two body junctions is not eliminated well in this way, this gap is to hinder, affect heat to hand over
The key changed, therefore its rate of heat exchange is low always；In addition the reel stress that cannot be overcome and the expansion system difference of two bodies are led
Gap is caused to be gradually increased to two body separation, thus service life is short；Using the method for embedded welding, although using titanium valve slugging than
High frequency is welded, but cost intensive, complex process, and the problem of interval station is still present.
At work, due to radiating, pipe surface is smooth for existing radiating tube, and medium forms laminar flow in Bottomhole pressure, is situated between
Matter heat exchange is uneven, is the heat transfer effect for strengthening radiating tube, and the general technological means for adopting are to install baffle plate additional in radiating tube, with
Increase turbulent flow, aggravate gas turbulence, strengthen heat transfer effect, but install baffle plate additional in radiating tube, the resistance of gas flowing can be increased
Power, slows down air flow rate, and heat transfer effect dies down, therefore the structure for installing baffle plate additional of radiating tube also needs further improvement.
The content of the invention
The utility model proposes a kind of helical fin and metal base tube gapless and the Composite Double gold of intraductal turbulance can be strengthened
Category exempts to cut painting one-shot forming radiating tube.
What the technical solution of the utility model was realized in：Bimetal composite exempts to cut painting one-shot forming radiating tube, including
The metal base tube of both ends open, the base tube two ends are provided with horizontal connecting portion, and two connecting portions are arranged on one directly
On line, several bending parts and straight sections are interval with the base tube, the base tube outside is additionally provided with several segmentations and is arranged
In the spiral aluminous fin of the straight sections.
Used as preferred technical scheme, the bending angle of the bending part is less than 170 ° more than 120 °.
Used as preferred technical scheme, the spiral aluminous fin root is provided with arc transition portion.
As preferred technical scheme, the dead in line of the axis of the straight sections and the connecting portion.
Used as preferred technical scheme, the axis of the straight sections overlaps with the bending part side.
This utility model is provided with bending part and straight sections due to metal base tube, after medium is entered in pipe, through bending part
Shi Fasheng slight reducing, changes the flow direction of medium, increased turbulent flow in pipe, strengthens heat transfer effect；Spiral aluminum is closed
Golden fin surface is smoothed, and beneficial to radiating, so as to improve its radiating efficiency, arc transition portion, axial wind is provided between helical fin
Speed is conducive to self-cleaning, prevents fin surface dust stratification, reduces heat transfer efficiency.
The bending angle of bending part is less than 170 ° more than 120 °, and bending angle is unlikely to too slow, when can make media flow
Generation reducing is to increase turbulent flow in pipe, and it is excessive to it also avoid bending angle, increases media flow resistance, while bending part bending angle
Degree too conference causes radiating tube to take up room greatly, therefore relatively gentle bending angle, and the impact that integrally takes up room on radiating tube is little,
Avoid and cause heat transmission equipment overall volume to increase because radiating tube takes up room greatly.
