Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
Fig. 1 to Fig. 3 is the structural representation of the device of the utility model embodiment.In figure, the direction of arrow indication is air current flow direction.
Composition graphs 1 to Fig. 3, the utility model 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 utility model embodiment, 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 utility model embodiment, often organize air to 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 the triangle wing plate of fin 1 one.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 utility model can improve about 5%, and the pressure loss reduces by 5%, and combination property can improve about 8%.
Another aspect of the present utility model, also provides a kind of heat exchanger comprising above-mentioned louvered fin.
Certainly, be more than preferred embodiment of the present utility model.It should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model general principle, can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
