Abstract
A variable B-shaped multichannel self-brazing cooling tube is formed by folding two strips in a snap mode. The same strip is identical in folding direction and height, two end faces of the stripsare folded in a circular-arc mode, the position is the welding snap position of the other strip, the other strip is also folded in the same direction of the first strip, the folded portions are staggered when two strips are aligned, and the folding height is identical to the folding height of the other strip. Two end faces of the strip are folded in a circular-arc mode, a circular arc is larger than a circular arc of the other strip and just wraps two circular-arc bends of two end sides of the other strip, two circular-arc faces just snap with each other, two strips oppositely adhere in the folding height direction, and multiple closed cross sections, namely channels are formed. The variable B-shaped multichannel self-brazing cooling tube can be widely applied to automobile radiators, automobile air conditioning condensers and evaporators.
Description
One, technical field
The utility model relates to a kind of B of change 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 uses 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 use composite material; Ratio-frequency welded tube can improve the deficiency of extruding pipe, surface can be with composite bed, but the equipment precision requirement of the mould of moulding, 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
The purpose of this utility model provides a kind of B of change 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, when 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 technological scheme that the utility model adopts is: a kind of B shape multichannel that becomes is from soldering cooling tube, formed by the folding interlock of two piece of tape, 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 1 band, folding part staggers in the time of 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, multiple 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 multiple walls, fold height is identical, when band two ends is fitted in central position, these folded wall and band are fitted again, form multiple 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 utility model 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 described in the utility model 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 described in the utility model 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 described in the utility model is become by wall scroll band Fold-Combined from soldering cooling tube formula.
Five, embodiment
Below technology of the present utility model is formed and is described in further detail.
Contrast Fig. 1, change B shape multichannel described in the utility model, from soldering cooling tube, is combined by band 1-1 and band 1-2, and band 1-1 is folded into multiple 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 multiple 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 multiple 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, the quantity that can change 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 described in the utility model, from soldering cooling tube, is formed by band 2-1 and band 2-2 Fold-Combined, and band 2-1 is folded into multiple 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, multiple 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 difference of band 2-1, the quantity that can change 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.
