As preferably, described flat fin is arranged in described fin surface thereof, and the angle between described flat fin and air current flow direction is less than 90 °.
As preferably, described fin is also provided with air and streams unit, described air stream unit comprise be located on described fin stream hole and with described stream that hole is connected stream plate.
As preferably, along air current flow direction, be provided with air described in a group before often organizing described radiating fin and stream unit, often organize described air stream unit comprise multiple described in stream hole and with described stream that hole is connected stream plate.
As preferably, often organize described air stream unit comprise two spaced described in stream hole and with stream hole described in two and be connected and stream plate.
As preferably, described in stream hole be symmetrically arranged tri-angle-holed along longitudinal midplane of described fin, described in stream plate and be and the triangle wing plate of described fin one.
As preferably, two described tri-angle-holed in a side be located near radiating tube mounting groove on described fin.
As preferably, described in the angle streamed between plate and air current flow direction be 45 °, described in the angle streamed between plate and described fin be 80 ° ~ 90 °.
Another aspect of the present invention, also provides a kind of heat exchanger, comprises above-mentioned louvered fin.
Apply technical scheme of the present invention, louvered fin, comprises fin, and fin is provided with many group radiating fins and the multiple radiating tube mounting grooves for installing radiating tube, radiating fin comprises louvered fin peace fin, and flat fin and louvered fin set gradually along air current flow direction.Owing to adopting flat fin Substitute For Partial louvered fin, effectively can reduce windage, reduce the power consumption of complete machine.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, but not as a limitation of the invention.
Fig. 1 to Fig. 3 is the structural representation of the device of the embodiment of the present invention.In figure, the direction of arrow indication is air current flow direction.
Composition graphs 1 to Fig. 3, the invention provides a kind of louvered fin, comprise fin 1, fin 1 is provided with many group radiating fins and the multiple radiating tube mounting grooves 10 for installing radiating tube, often organize radiating fin and comprise the peaceful fin 21 of louvered fin 22, flat fin 21 and louvered fin 22 set gradually along air current flow direction.In the embodiment of the present invention, many group radiating fins and multiple radiating tube mounting groove 10 interval are arranged.
Preferably, be provided with dividing plate 23 between flat fin 21 and louvered fin 22, flat fin 21 is located at the windward side of dividing plate 23, and louvered fin 22 is located at the leeward side of dividing plate 23.Flat fin 21 is arranged in fin 1 surface thereof, and the angle between flat fin 21 and air current flow direction is less than 90 °.Due in windward side region, heat exchange property is better, flat fin 21 is adopted in this region, too much influence can not be produced to the exchange capability of heat of whole louvered fin, still can ensure the requirement meeting heat exchange, but adopt flat fin 21, can well windage be reduced, then reach the effect reducing Overall Power Consumption.
Preferably, along air current flow direction, often organize and be provided with one group of air before radiating fin and stream unit, for increasing the disturbance of air further and strengthening the exchange capability of heat of fin 1, often organize air stream unit can comprise multiple stream hole 31 and with stream that hole 31 is connected stream plate 32.
In the embodiment of the present invention, often organize air and stream unit and comprise two intervals and arrange and stream hole 31 and stream plate 32, stream hole 31 be along longitudinal midplane of fin 1 symmetrically arranged two tri-angle-holed, streaming plate 32 is and fin 1 triangle wing plate integrally.Two tri-angle-holed and triangle wing plates be located at respectively on fin 1 near the side of radiating tube mounting groove 10 and on uprush flow direction the opposite side at interval with it.Wherein, triangle wing plate near radiating tube mounting groove 10 can strengthen air agitation and turbulence intensity, the exchange capability of heat in further reinforcement radiating fin region, be located at the triangle wing plate of opposite side, namely the triangle wing plate before being located at radiating fin, effectively can reduce wake zone, i.e. the area in the region that exchange capability of heat is faint, strengthen the exchange capability of heat in leeward region.
Preferably, the angle streamed between plate 32 and air current flow direction is 45 °, and the angle streamed between plate 32 and fin 1 is 80 ° ~ 90 °, so that withdrawing pattern.Along parallel airflow flow direction and uprush flow direction, the radius of radiating tube mounting groove 10 is equal near the vertical range between the center of gravity of triangle wing plate and the straight line at the diameter place of adjacent radiating tube mounting groove 10 of radiating tube mounting groove 10, the height of triangle wing plate is 2/3 of the spacing between flat fin 21, to reduce the area of managing rear wake zone, strengthen exchange capability of heat.
Prove through experiment, compared with existing louvered fin, the exchange capability of heat of louvered fin of the present invention can improve about 5%, and the pressure loss reduces by 5%, and combination property can improve about 8%.
Another aspect of the present invention, also provides a kind of heat exchanger comprising above-mentioned louvered fin.
Certainly, be more than the preferred embodiment of the present invention.It should be pointed out that for those skilled in the art, under the prerequisite not departing from its general principles, can also make some improvements and modifications, these improvements and modifications are also considered as protection scope of the present invention.
