Description
Technical field
The invention belongs to heat exchanger technology field, refer in particular to a kind of heat-exchanger fin with chamfering.
Background technology
Along with the increasingly stringent of emission request, EGR Technology is applied on power set more and more, and various structure heat exchanger produces in succession.Wherein, plate-fin structure heat exchanger, because of the heat dispersion of its brilliance, is more applied.
Conventional plate-fin structure heat exchanger, arranges gas side fin in its gas side.Gas side fin is mainly used in the coefficient of heat transfer strengthening gas side, improves the radiating efficiency of cooler.But in some applications, space is more limited, need the cooler of more high cooling efficiency.
Summary of the invention
The object of this invention is to provide a kind of promote cooler heat transfer efficiency, guarantee between fin and cooling tube the heat-exchanger fin of weld strength reliably with chamfering.
The object of the present invention is achieved like this:
A kind of heat-exchanger fin with chamfering, include corrugated fin, sidewall on fin between crest and trough is provided with the continuous print corrugated channel formed is set along finned length direction by several unit ripples, the wavelength of described unit ripple is 3-5mm, and the wave amplitude of described unit ripple is 0.3-0.8mm.
Above-mentioned fin is rectangular planes at crest and trough place.
Chamfering is provided with between the two side at the crest of above-mentioned fin and trough and unit ripple place.
The adjacent two side of above-mentioned fin be arranged in parallel or arranges in splayed or arrange in herringbone.
The adjacent two side of above-mentioned fin is splayed when arranging or arrange in herringbone, and the angle between adjacent two side is 4 °-30 °.
The present invention gives prominence to compared to existing technology and useful technique effect is:
1, continuous print corrugated channel of the present invention can promote the heat transfer efficiency of cooler.
2, crest of the present invention and trough place are plane, guarantee that the weld strength between fin and cooling tube is reliable.
3, the present invention arranges chamfering at the crest of fin and trough place, in the easier regulating tooth distance of width, and more easily can manufacture like this; Can increase the wall flow-disturbing with cooling tube contact site, the heat-transfer effect of a strengthening area of dissipation, promotes the heat transfer efficiency of cooler simultaneously.
4, form an angle between sidewall adjacent between two of the present invention setting, can increase addendum width, namely increases the area that fin contacts with cooling tube.
5, the present invention can be widely used on various heat exchanger, particularly the heat exchange fin of gas side in cooler for recycled exhaust gas.

Detailed description of the invention
Below in conjunction with accompanying drawing, with specific embodiment, the invention will be further described, see Fig. 1-6:
A kind of heat-exchanger fin with chamfering, include corrugated fin, sidewall 3 on fin between crest 1 and trough 2 is provided with the continuous print corrugated channel formed is set along finned length direction by several unit ripples 4, the wavelength a of described unit ripple 4 is 3-5mm, and the wave amplitude b of described unit ripple 4 is 0.3-0.8mm.
Above-mentioned fin is plane at crest 1 and trough 2 place.
Chamfering 5 is provided with between the crest 1 of above-mentioned fin and the two ends of trough 2 and unit ripple 4.Chamfering 5 is set at the crest 1 of fin and trough 2 place, in the easier regulating tooth distance of width, and more easily can manufactures like this; Can increase the wall flow-disturbing with cooling tube 6 contact site, the heat-transfer effect of a strengthening area of dissipation, promotes the heat transfer efficiency of cooler simultaneously.
The adjacent two side 3 of above-mentioned fin is for be arrangeding in parallel or arranging in splayed or arrange in herringbone.As: often to organize between adjacent two side 3, crest 1 place in herringbone, adjacent two side 3, trough 2 place in splayed, crest 1 and the width at trough 2 place can be increased like this, namely increase the area that fin contacts with cooling tube 6; Or often to organize between adjacent two side 3, crest 1 place in splayed, adjacent two side 3, trough 2 place in herringbone, the angle α between two side 3 is 4 °-30 °.
The present invention is arranged in cooling tube 6, and crest 1 welds with the inwall of cooling tube 6 with the plane at trough 2 place.
Above-described embodiment is only preferred embodiment of the present invention, not limits the scope of the invention according to this, therefore: all equivalence changes done according to structure of the present invention, shape, principle, all should be covered by within protection scope of the present invention.
