Abstract
The utility model relates to a screw winding heat exchange tube used in tubular heat exchanger, provided with a tube. The utility model is characterized in that the outer wall of the tube is coiled with at least one metal wire. The utility model can avoid scale and thermal resistance of prior machined screw heat exchange tube, with stable quality, low metal consumption, and low production cost, which can be used in tubular heat exchanger.
Description
(1) technical field: the utility model relates to the manufacturing technology of tubular heat exchanger, particularly a kind of tubular heat exchanger spiral wrapping wire heat exchanger tube.
(2) background technology: the heat exchange principle of tubular heat exchanger is: with two kinds of outer hot and cold media of pipe, carry out heat exchange by tube wall in the flowing pipe.Generally, therefore the exothermic coefficient difference of two kinds of different mediums will carry out ribization in low exothermic coefficient one side (being the pipe outside generally speaking), to increase its heat exchange area, makes its heat release equal heat absorption substantially.It all is to take the method for rolled threaded silk that at present domestic and international heat exchanging tube outer surface carries out ribization, promptly claims screwed pipe.
The heat transfer technology both domestic and external field that is applied in of screwed pipe is used very extensive.Though solved heat exchange pipe external surface rib problem easily, had a lot of not enough aspects in actual applications:
1. thread surface all adopts and rolls a cutter and be rolled on lathe or other special equipment.Its rolled surface is rough.After heat exchanger used a period of time, the dirt particles in the fluid was easy to fill and lead up sometimes even with screw thread attached to its surface and place, dead angle.Form very big dirtiness resistance, seriously influenced the heat exchange efficiency of heat exchanger.
Cooling tube rolling after, be easy to generate internal stress.Though the manufactory that has has adopted the annealing means, also bad or annealing temperature is inhomogeneous because of the control of the rolling degree of depth, produce phenomenon of rupture in the practice usually, after being mixed, two media causes bigger economic loss.
3. in general, roll the heat exchanger tube that fiber tube must adopt relatively thick, generally be not less than 1.5 millimeters, shown in the consumption of metal big, product cost increases.
4. screwed pipe is restricted to the pipe material, in general, and T
2Pipe or HSn70-1 pipe or copper/aluminium composite pipe are easier to rolling, and can not be rolling to the bigger material of hardness such as stainless steel tube, and be therefore inapplicable for the fluid of high deep-etching.
5. inconvenience is cleaned in maintenance, and the dirt of tube outer surface is difficult for rinsing out.
(3) summary of the invention: the purpose of this utility model will overcome existing thread cutting heat exchanger tube exactly and form dirtiness resistance easily, clean inconvenience, the crudy instability, the metal material consumption is big, problems such as product cost height provide a kind of tubular heat exchanger spiral wrapping wire heat exchanger tube.
Concrete scheme of the present utility model is: the outer wall spiral at common light pipe body installs around at least one wire.
The wire that installs around at the tube wall spiral in the utility model has the 3-5 head.
Its pitch of spiral metal wire of the utility model middle tube body outer wall is 2-4mm.
The wire diameter that installs around in the utility model at tube wall is 0.8-1.5mm.
The weldering of spiral metal wire and body is one in the utility model.
The wall thickness of the utility model middle tube body is 0.6-1.0mm.
The utility model has the following advantages compared with the prior art:
1. because the wire surface of wrapping wire pipe is very smooth, and the fillet that scolder forms naturally also is smooth no dead angle, it is self-cleaning that the coarse pitch that adds the formation of bull wrapping wire has been strengthened washing away of fluid.Avoided the accumulation of fluid fine particle to greatest extent, permanent use can not form dirtiness resistance.
2. heat exchanger tube can not produce stress and flow harden phenomenon without any processing.And wire can also play antivibration and the protection parent tube effect, product is durable in use.
3. can significantly reduce the wall thickness of heat exchanger tube, in general can reduce half, production cost is reduced significantly.
4. the material of heat exchanger tube is applied widely, the applied range of product.
5. maintenance is cleaned conveniently, and the dirt of tube-surface rinses out easily.
(4) description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1-body, 2-wire, 3-scolding tin.
(5) specific embodiment:
Example 1: referring to accompanying drawing, it is body 1 that the utility model adopts stainless steel tube, and its wall thickness is 0.6, install around the stainless steel wire 2 of a φ 0.8mm at the outer wall spiral of body 1, pitch is elected 2mm as, and adopts scolding tin 3 that stainless steel wire 2 and body 1 weldering are one, promptly constitutes the utility model.
Example 2: the utility model adopts T
2Pipe is for body 1, and its wall thickness is 1.0mm, has installed around 3 (or 2,4,5 all can) at the outer wall spiral of body 1, the copper wire 2 of φ 1.5mm, and pitch is 4mm, adopts brazing that copper wire 2 and body 1 weldering are promptly constituted the utility model for one.
Claims (6)
1. tubular heat exchanger has body with spiral wrapping wire heat exchanger tube, and it is characterized in that: the outer wall spiral at body has installed around at least one wire.
2. tubular heat exchanger according to claim 1 spiral wrapping wire heat exchanger tube, it is characterized in that: the wire that installs around at the tube wall spiral has the 3-5 head.
3. tubular heat exchanger according to claim 1 and 2 spiral wrapping wire heat exchanger tube, it is characterized in that: its pitch of the spiral metal wire of tube wall is 2-4mm.
4. tubular heat exchanger according to claim 1 and 2 spiral wrapping wire heat exchanger tube, it is characterized in that: the wire diameter that installs around at tube wall is 0.8-1.5mm.
5. tubular heat exchanger according to claim 1 and 2 spiral wrapping wire heat exchanger tube is characterized in that: spiral metal wire and body weldering are one.
6. tubular heat exchanger according to claim 1 and 2 spiral wrapping wire heat exchanger tube, it is characterized in that: the wall thickness of body is 0.6-1.0mm.
