Abstract
The invention relates to a variation B-shaped multi-channel self-brazing cooling pipe which is formed by folding two strips in a meshed mode. The same strip is folded in the same direction and has the same height. The two end faces of the strip are folded in an arc mode. The arc end faces are welding meshed places with the other strip. The other strip and the first strip are folded in the same direction. The folded parts are staggered when the two strips are aligned. The folding height is equal to the folding height of the other strip. The two end faces of the strips are folded in an arc mode. The arc is larger than the arc of the other strip and just covers two arc bends of the two end sides of the other strip. The two arc faces are rightly meshed and the two strips oppositely adhere to each other in the folding height direction, namely multiple sealed sections which are also channels are formed. The variation B-shaped multi-channel self-brazing cooling pipe can be widely applied to an automobile radiator, an automobile air conditioning condenser and an evaporator.
Description
One, technical field
The present invention relates to a kind of change B shape multichannel from soldering cooling tube, for automobile or engineering machinery radiator and air-conditioning condenser, vaporizer, can substitute single hole porous ratio-frequency welded tube and the micro-channel tubes of present use.
Two, background technique
Automobile or engineering machinery radiator generally adopt ratio-frequency welded tube, also have some to use micro-channel tubes is extruding pipe; Air-conditioning condenser and at present New Evaporator are all parallel stream structures, belong to corrugated tube type structure, and heat dissipating pipe is used micro-channel tubes.These heat dissipating pipes are mainly ratio-frequency welded tube, collapsible tubing and extruding pipe, and extruding pipe speed of production is slow, and efficiency is low, and tube-surface cannot be used composite material; Ratio-frequency welded tube can improve the deficiency of extruding pipe, surface can be with composite bed, but the mould of moulding is, the equipment precision requirement of soldering is high and expensive, because being is formed by band soldering, substantially outer wall even thickness, pipe two and tube wall are that single material is thick.
Three, summary of the invention
Object of the present invention provides a kind of change B shape multichannel from soldering cooling tube, can make as required the micro passage of varying number, be used for automobile or engineering machinery radiator and air-conditioning condenser, vaporizer, cooling tube tube-surface can be with solder layer, during tubulation, do not need welding, only need moulding, can enter stove from soldering; Speed of production is fast, and efficiency is high, and equipment and mold cost is low.
In order to address the above problem, the technical solution adopted in the present invention is: a kind of change B shape multichannel is from soldering cooling tube, by the folding interlock of two piece of tape, formed, the folding direction of same band is consistent, highly identical, band both ends of the surface become circular arc folding to turn over, it is seam interlock place with another piece of tape herein, and another piece of tape is also folding with the same direction of article one band, folding part staggers when two band alignment, folding height is identical with another piece of tape fold height, band both ends of the surface become circular arc folding to turn over, this circular arc is greater than another piece of tape circular arc, and just encase two circular arc bendings on another limit, piece of tape two ends, these two just interlocks of arc surface, two piece of tape are fitted relatively by fold height direction, a plurality of closed cross-sections have been formed, it is multichannel.
Described cooling tube forms by a piece of tape is folding, band is bent into circular-arc at width direction by required burst, and between circular arc and end face, be folded into a plurality of walls, fold height is identical, when band two ends is fitted in central position, these folded wall and band are fitted again, form a plurality of closed cross-sections, and these cross sections are multichannel walls.
The width of described band is determined according to the folding quantity of need, and folding quantity is set as required, and the length of tube being folded into can free severing.
The beneficial effect that the present invention reaches is:
1. speed of production is fast, and equipment and mold cost is low.
2. band is folded into tubular directly assemble afterwards, enters stove soldering voluntarily, does not need to carry out other mode seam again.
3. pipe two ends is wherein equivalent to have two material thick-layers, can improve pipe intensity.
Four, accompanying drawing explanation
Fig. 1 is that change B shape multichannel of the present invention is the structural representation being become by two piece of tape Fold-Combineds from soldering cooling tube.
Fig. 2 is that change B shape multichannel of the present invention is structural representations folding by wall scroll band, two piece of tape combinations from soldering cooling tube.
Fig. 3 is the structural representation that change B shape multichannel of the present invention is become by wall scroll band Fold-Combined from soldering cooling tube formula.
Five, embodiment
Below technology of the present invention is formed and is described in further detail.
Contrast Fig. 1, change B shape multichannel of the present invention, from soldering cooling tube, is combined by band 1-1 and band 1-2, and band 1-1 is folded into a plurality of conduit wall 1-3, and the wide both sides of band end face bends becomes arc surface 1-7; Band 1-2 is folded into a plurality of conduit wall 1-4, and the wide both sides of band end face is folded into arc surface 1-6; After two piece of tape are folding, fit in a plurality of passage 1-5, two terminal circle cambered surface 1-6 and arc surface 1-7 interlock, form the two edge channel 1-8 that seal; From cross section, be the multichannel of pipe, heat eliminating medium can be from multichannel 1-5 and two passage 1-8 stream strings, multichannel 1-5 can be changeable as required, only need the band 1-1 conduit wall 1-3 folding with band 1-2 different with conduit wall 1-4 foldable number, can change the quantity of multichannel 1-5, the width of band is determined according to the quantity of required folded wall; The free severing as required of the length of the pipe being folded into.
Contrast Fig. 2, change B shape multichannel of the present invention, from soldering cooling tube, is formed by band 2-1 and band 2-2 Fold-Combined, and band 2-1 is folded into a plurality of folded wall 2-3, and the wide both sides of band end face bends becomes arc surface 2-6; The wide both sides of band 2-2 end face is folded into arc surface 2-5; After two piece of tape coordinate, a plurality of folded wall 2-3 and zone face laminating form multichannel 2-4, two terminal circle cambered surface 2-5 and arc surface 2-6 interlock, and folded wall 2-3 and end face arc surface form two edge channel 2-7 of sealing; From cross section, be the multichannel of pipe, heat eliminating medium can be from multichannel 2-4 and two passage 2-7 stream strings, multichannel 2-4 can be changeable as required in addition, only need the folding folded wall 2-3 foldable number of band 2-1 different, can change the quantity of multichannel 2-4, the width of band is determined according to the quantity of required folded wall; The free severing as required of the length of the pipe being folded into.
