Abstract
A wave-shaped multi-channel self-brazing cooling pipe is formed by folding and combining a strip. One end of the strip is folded into a plurality of channel walls, the other end of the strip is bent into an arc to form a sealed pipe cross section, the strip is matched with pipe hole inner cross sections after being folded to form a plurality of channels, two end faces of the strip are bent to form an arc snapping part, the number of the channels can be changed as required and is determined through the folding wave number of the folded strip, and the length of the pipe can be freely cut as required. The wave-shaped multi-channel self-brazing cooling pipe can be widely applied to automobile radiators, automobile air conditioning condensers and evaporators.
Description
One, technical field
The present invention be a kind of wave multichannel from soldering cooling tube, for automobile or engineering machinery radiator and air-conditioning condenser, evaporimeter, can substitute single hole porous ratio-frequency welded tube and the micro-channel tubes of present use.
Two, background technology
Automobile or engineering machinery radiator generally adopt ratio-frequency welded tube, have some also to use micro-channel tubes is extruding pipe; Air-conditioning condenser and at present new evaporimeter trend are all concurrent flow structures, belong to pipe racks material formula structure, and radiating tube is used micro-channel tubes.These radiating tubes are mainly ratio-frequency welded tube, folded tube 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 weak point 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 outside wall surface 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 wave multichannel from soldering cooling tube, can make as required the microchannel of varying number, be used for automobile or engineering machinery radiator and air-conditioning condenser, evaporimeter, 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 wave multichannel, from soldering cooling tube, combines after being folded by a piece of tape, and one of band is folded into a plurality of conduit walls, and other end is bent into circular arc and forms sealed tube cross section; Band folds cross section in rear and pore and fits in a plurality of passages, and band both ends of the surface are bent into circular arc interlock.
Described band two end faces is converted into inside and outside circular arc interlock, and the band head of inner face does not cut off, and in pipe, extends, and is folded into a plurality of waveforms.
The corrugated wave height of described band is identical, and crest, trough and inside pipe wall are just fitted.
Between the waveform of described band, form a plurality of closed cross-sections.
The waveform strip surface of described band, with composite bed, is entered slice postwelding, band head interlock place seam, and a plurality of crests that band is folded into, trough and the joint place seam of band face, form the openning of a plurality of sealings, i.e. multichannel.
The invention has the beneficial effects as follows:
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 equivalent to have two material thick-layers, can improve pipe intensity.
Four, accompanying drawing explanation
Fig. 1 is that wave multichannel of the present invention is from soldering cooling tube triangular wave structural representation.
Fig. 2 is that wave multichannel of the present invention is from soldering cooling tube trapezoidal wave structural representation.
Fig. 3 is that wave multichannel of the present invention is from soldering cooling tube square wave structural representation.
Five, the specific embodiment
Below technology of the present invention is formed and is described in further detail.
Contrast Fig. 1, wave multichannel of the present invention is from soldering cooling tube, by band 1-1 is folding, form, band 1-1 is folded into left arc surface 1-2, right arc surface 1-10, an arc surface 1-3, forms a closed cross-section, it is the large cross section of cooling tube, band is folded into arc surface 1-3 and extends to pipe inside, makes a plurality of triangular waves, crest and trough and the laminating of band face, upper ripple 1-4 and lower ripple 1-5 form the multichannel 1-7 of a plurality of sealings, and band head 1-9 is folded into circular arc and circular arc 1-10 interlock; Multichannel 1-7 quantity is set as required, can change by changing wave number 1-4 and 1-6, and cooling medium, by multichannel 1-7 and two ends, left and right passage 1-5 and 1-8 stream string, reaches radiating effect, enters these contact-making surface seam of slice postwelding, forms multi-channel tube; In pipe, folding band can be windowed and also can not windowed; The cooling tube length that this is folded into free severing as required.
Contrast Fig. 2, wave multichannel of the present invention is from the trapezoidal wave cooling tube of soldering cooling tube, and its embodiment is same as Fig. 1, except folding waveform is that trapezoidal wave is not identical.
Contrast Fig. 3, wave multichannel of the present invention is from the square wave cooling tube of soldering cooling tube, and its embodiment is same as Fig. 1, except folding waveform is that square wave is not identical.
Wave multichannel of the present invention, from soldering cooling tube, can also be transformed into various waveform cooling tubes.
