Abstract
The invention belongs to the technical field of heat exchanger and particularly relates to a heat exchanger fin with chamfers. The fin comprises a corrugated fin body. Continuous corrugated slots are formed on the side walls, between crests and troughs, of the fin body. The slots are formed by a plurality of unit waves and arranged along the length direction of the fin body. Each unit wave is 3-5mm in length and 0.3-0.8mm in amplitude. The heat exchanger fin has the advantages that the chamfers are disposed at the crests and the troughs, tooth pitch in the width direction can be adjusted easily, easy manufacturing is achieved, wall surface turbulent flow of the parts in contact with a cooling pipe can be increased, heat transfer effect of primary radiating area can be intensified, and the heat transfer efficiency of a cooler can be increased; an included angle is formed between every two adjacent side walls, so that tooth top width can be increased, namely the contact area of the fin and the cooling pipe is increased; the heat exchanger fin is widely application to various heat exchangers, especially air-side heat exchangers of waste gas recycling coolers.
Description
Technical field
The invention belongs to heat exchanger technical 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 exchangers produce in succession.Wherein, plate-fin structure heat exchanger, because of its remarkable heat dispersion, is more applied.
Conventional plate-fin structure heat exchanger, arranges gas side fin in its gas side.Gas side fin is mainly used in strengthening the coefficient of heat transfer of gas side, improves the radiating efficiency of cooler.But in some applications, space is more limited, need the more cooler of high cooling efficiency.
Summary of the invention
The object of this invention is to provide a kind of heat transfer efficiency that promotes cooler, guarantee the weld strength heat-exchanger fin with chamfering reliably between fin and cooling tube.
The object of the present invention is achieved like this:
A kind of heat-exchanger fin with chamfering, include corrugated fin, on sidewall on fin between crest and trough, be provided with the continuous corrugated channel forming 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.
Between the two side at the crest of above-mentioned fin and trough and ripple place, unit, be provided with chamfering.
The adjacent two side of above-mentioned fin be arranged in parallel or is splayed setting or is herringbone setting.
The adjacent two side of above-mentioned fin is splayed setting or is herringbone while setting, and the angle between adjacent two side is 4 °-30 °.
The present invention compared to existing technology outstanding and useful technique effect is:
1, continuous 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 crest and the trough place of fin, like this can be in the easier regulating tooth distance of width, and more easily manufacture; While can increase the wall flow-disturbing with cooling tube contact site, the heat-transfer effect of an area of dissipation of strengthening, the heat transfer efficiency of lifting cooler.
4, the setting that forms an angle between adjacent sidewall between two of the present invention, can increase addendum width, increases the area that fin contacts with cooling tube.
5, the present invention can be widely used on various heat exchangers, particularly the heat exchange fin of gas side in cooler for recycled exhaust gas.

The specific embodiment
Below in conjunction with accompanying drawing, with specific embodiment, the invention will be further described, referring to Fig. 1-6:
A kind of heat-exchanger fin with chamfering, include corrugated fin, on sidewall 3 on fin between crest 1 and trough 2, be provided with the continuous corrugated channel forming 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 with trough 2 places.
Between the crest 1 of above-mentioned fin and trough 2 and the two ends of unit ripple 4, be provided with chamfering 5.Crest 1 and trough 2 places at fin arrange chamfering 5, like this can be in the easier regulating tooth distances of width, and more easily manufacture; While can increase the wall flow-disturbing with cooling tube 6 contacts site, the heat-transfer effect of an area of dissipation of strengthening, the heat transfer efficiency of lifting cooler.
The adjacent two side 3 of above-mentioned fin is for be arrangeding in parallel or being splayed setting or being herringbone setting.Between two side 3 as adjacent in: every group of crest 1 place, be herringbone, trough 2 adjacent two sides 3, place are splayed, can increase like this width at crest 1 and trough 2 places, increase the area that fin contacts with cooling tube 6; Or between adjacent two side 3, every group of crest 1 place, be splayed, trough 2 adjacent two sides 3, place are herringbone, the angle α between two side 3 is 4 °-30 °.
The present invention is arranged in cooling tube 6, crest 1 and the plane at trough 2 places and the welding of the inwall of cooling tube 6.
Above-described embodiment is only preferred embodiment of the present invention, not limits the scope of the invention according to this, therefore: all equivalences of doing according to structure of the present invention, shape, principle change, within all should being covered by protection scope of the present invention.
