Description
Technical field
It is specially a kind of empty for automobile or engineering machinery, household the utility model is related to radiating device technical field
Condensers and the evaporator folded tubes such as tune.
Background technology
Parallel-flow heat exchanger generally uses heat-exchanging part of the micro-channel flat as its core, since its general aperture is inclined
It is small, it is therefore desirable to which that large-size extruder could realize molding, and large-size extruder price is all more expensive, and maintenance cost can also increase
Add the cost of pipe.Due to the use of the abrasion for being Hot-extrusion, also there is quickly for profile extrusion die, can not the company of being formed
Continuous production；Micro-channel flat can not directly form erosion resistant coating due to being limited by extrusion process, can only be realized by spraying zinc technology
Electrochemical anti-corrosive has certain pressure for environmental protection, and uneven coating is even, and anti-corrosive properties also have significant limitation；It is existing
It being processed together with conventional flat pipe and waveform flow-disturbing band Split assembled, structure design is unreasonable, and operation processing is complicated,
And corrugated wave crest and trough are contacted on the inside of flat tube for line, are not easy to weld, are caused product quality problem, thus urgently
It needs to research and develop a kind of heat-dissipating pipe of whole integral structure.
Invention content
The purpose of this utility model seeks to provide a kind of air-conditioning heat exchanger folded tube, and generally integral type, structure is set

Stream band constitutes 1/2 bilateral symmetry, and left and right two parts are connected in intermediate pairing, and row is contacted at face, and upper tube wall is closely intermediate
End is that integral type is connect with the flow-disturbing strap end portion of homonymy, and flow-disturbing band is rectangle waveform or trapezoidal waveform, is arranged in upper tube
Between wall and lower tube wall, contacted for face between wave crest and upper tube wall, between trough and lower tube wall；The flow-disturbing band outer end
It is provided with one section of segmental arc, radian is identical as arc-shaped edges, and segmental arc is bonded with arc-shaped edges.
Further, the flow-disturbing band is connect by rectangular bends with upper tube wall, and the rectangular bends on right side are " Contraband ", and two
The vertical edge of a rectangular bends is in close contact connection back-to-back, and upper and lower triangle zone is formed at the rectangular bends upper and lower end of both sides,
The a diameter of 0.15-0.18mm of circumcircle of the upper triangle zone of the rectangular bends, the circumcircle of lower triangle zone are a diameter of
0.18mm；
Preferably, a diameter of 0.18mm of circumcircle of the upper triangle zone of the rectangular bends, lower triangle zone, circumcircle
Place（Corner）Extra material can increase intensity and corrosion resistance with the angles R by forming unified entirety after soldering, for
The impact for resisting external carbuncle also has certain auxiliary.
The described integral type connection, be upper tube wall, lower tube wall, flow-disturbing band, rectangular bends by one block of plate after mechanical bending
Molding, and the other forms such as non-solder are integrally fixed.
Further, the upper tube wall, lower tube wall, flow-disturbing band are lamination layer structure, including intermediate metal layer and
The solder layer of metal layer positive and negative.
The integral thickness of the flat tube between 1.8-2mm, the upper tube wall, lower tube wall, flow-disturbing band thickness
Degree is 0.2 ± 0.01, and flow-disturbing band and the interface width of upper and lower tube wall are more than or equal to 0.2mm.
It is respectively formed the rectangle being intervally arranged between the flow-disturbing band and upper tube wall and lower tube wall or trapezoid cross section is logical
Except at road, rectangular bends and segmental arc.
Because entire flat tube connects for integral type, an entire plate is selected to be processed before moulding, at
Type process：Inside there is into flow-disturbing first and reinforces the flow-disturbing band machine-shaping of intensity effect, specifically by the plank of lamination layer structure
Two ends respectively by arrangement roll be processed, trapezoidal or rectangle wave is converted by roll-in roll-forming technology
Shape, and most end is rolled into segmental arc, and both ends molding flow-disturbing band edge part is then formed rectangular bends by bending twice,
At this point, flow-disturbing band one side is contacted with plate, then by doubling at segmental arc, molding flow-disturbing band another side is also contacted with plate,
The fitting that two rectangular bends are finally formed in plate centre position constitutes the flat tube of generally long 0 type, and inside, which is divided into, waits flow-disturbings
Tape channel, the wave crest and trough of flow-disturbing band are just bonded with the inner face of upper and lower tube wall, while the side end and arc-shaped side of flow-disturbing band
Fitting, for welding together after being subsequently brazed.
The beneficial effects of the utility model are：
The heat-dissipating pipe that this utility model is related to uses cold-bending molding technology, and process equipment is simple, of low cost, production efficiency
It is high；Integral structure row at folded tube, intensity is high, and heat dissipation performance is small, light-weight, alternative traditional micro-channel tubes, is applicable in
It is in extensive range；The circumscribed circular diameter of rectangular bends of symmetric involution structure is small, is bonded on the inside of flow-disturbing band tail end segmental arc and arc-shaped edges,
So that soldering effect is good, intensity further strengthens, and also strengthens anticorrosive and external carbuncle destruction.
