Abstract
The present invention relates to a kind of manufacture method and surface cooler of corrugated radiating pipe of surface cooler.The heat exchanger that surface cooler is integrated mill, restaurant, the public arena did not lack.The radiating tube of surface cooler is surface cooler heat exchange property the best of corrugated radiating pipe.But at present for various reasons, this surface cooler is in the inner development stage.The present invention discloses that a kind of this method of manufacture method of corrugated radiating pipe is simple, and cost is low, produces the ripple radiating tube in this way and makes surface cooler, and heat exchange property is fine.
Description
The present invention relates to a kind of manufacture method of corrugated radiating pipe of surface cooler and the surface cooler of producing with the control of this kind corrugated radiating pipe.
Surface air cooler can be used to that air is carried out the wet type cooling, and (separate out condensed water, dry type cooling (water capacity is constant during the air cooling) and heating usefulness during the air cooling, it is integrated mill, restaurant, the indispensable heat exchanger in public arena.Radiating tube is the parts of most critical in the surface cooler, existing state, inside and outside surface cooler is all had research, everybody is consistent to think that radiating tube is surface cooler heat exchange property the best of corrugated radiating pipe, but only limits at present in-house research, closed test stage, its reason is complex process, the processing cost height.External a kind of circle corrugated pipe is a tube-pulling craft recently, apparatus expensive, complex process.The manufacture method that the present invention proposes a kind of new production ripple radiating tube is the corrugated radiating pipe manufacture method, and this is a kind of dual damascene shape radiating tube manufacture method.It at first rolling go out inner corrugated pipe sheet and outward corrugated tube sheet, the rolling method of interior outward corrugated tube sheet is identical, it is the center ripple that shuts out inside and outside ripple section of jurisdiction with one group of smooth rolling wheel that bellows-shaped is arranged, the center ripple can be two, also can be one, rolling goes out two ripples on ripple both sides, center then, rolling goes out two ripples in both sides of ripple both sides, center ripple again, analogize one by one, rolling goes out the inside and outside corrugated plate of required number ripple, with inside and outside corrugated plate linking machine joint close, two is welded top connection again and is formed.The inside and outside corrugated plate together rollforming that also can overlap also can be distinguished independent rollforming.Said method all is the multiple tracks technique for rolling, but this multiple tracks technology can be designed comparatively simple Special Equipment Continuous Flow waterline production, thereby greatly reduces cost, has also improved production efficiency.The waveform radiator that produces in this way is to be meniscate (as shown in Figure 4).Its inner corrugated pipe sheet (as shown in Figure 5) is crescent, inside radius r1 is 90～100mm, outer radius r2 is 96～106mm, two, ripple section of jurisdiction has respectively stretches out h1, h2 for joint close, each ripple height h3 of corrugated plate is 4～10mm, two limits of ripple are also asymmetric, and long limit a1 is 5～10mm, and minor face a2 is 2～5mm.The outward corrugated tube sheet also is crescent (as shown in Figure 6), inside radius r3 is 97～105mm, outer radius r4 is 103～111mm, two of ripple section of jurisdiction has respectively stretches out h4, h5 for joint close, each ripple height h6 of ripple section of jurisdiction is 4～10mm, two limits of ripple are also asymmetric, and long limit a3 is 5～10mm, and minor face a4 is 2～5mm.The all ripply corrugated radiating pipe in this inside and outside section of jurisdiction, because its this special version, thereby two evident characteristics are arranged, the one, save expansion tube process, and the ripple radiating tube can be closely cooperated with radiated rib, the 2nd, increase turbulent flow, thereby increased the coefficient of heat transfer, promptly increased the effect of heat exchange.
With the surface cooler (as shown in Figure 1, 2, 3) that this corrugated radiating pipe produces, rate of heat exchange is better than other surface cooler, is further described below in conjunction with 1,2,3 pairs of surface coolers of accompanying drawing.In the drawings: 1 is corrugated radiating pipe, promptly is meniscate corrugated radiating pipe with what the said method rolling went out, and it has even number, two is one group, and one two all connect elbow 6, another first tap into water pipe 5, one picks out water pipe 8, and all corrugated radiating pipes are all vertically placed; 2 is side plate, and side plate has two plates, is contained in both sides respectively; 3 is dividing plate, and dividing plate 3 upper punches are shaped on and the identical hole of corrugated radiating pipe 1 shape, and dividing plate has several piece, all goes here and there on all corrugated radiating pipes 1 of surface cooler, becomes 5 °～25 ° oblique angles simultaneously with corrugated radiating pipe; 4 is radiated rib, and the radiated rib upper punch is shaped on and the identical hole of corrugated radiating pipe 1 shape, radiated rib or the string on two one group corrugated radiating pipe 1, or the string on the whole corrugated radiating pipe 1 of surface cooler, and with 1 one-tenth 5 °～25 ° oblique angle of corrugated radiating pipe; 7 is joint, for the welding of corrugated radiating pipe 1 and water inlet pipe 5, outlet pipe 8 works the effect of connecing that is.Its operation principle is such; Cold water or hot water enter corrugated radiating pipe 1 by water inlet pipe 5, behind elbow 6, enter corrugated radiating pipe 1 again, flow out because the pressure of water through outlet pipe 8 again, corrugated radiating pipe 1 is swollen, corrugated radiating pipe and radiated rib 4, dividing plate 3 are combined closely, play good conductive force.Again because corrugated radiating pipe 1 is vertical placement, and dividing plate 3, radiated rib 4 become 5 °～25 ° oblique angles with it, this all helps surface cooler with air cooling the time, on corrugated radiating pipe 1, on the dividing plate 3 and the water droplet of forming on the radiated rib 4 utilize self gravitation to flow in the pond, influence heat exchange and be unlikely to form moisture film.
