Description
Technical field
The utility model relates to a kind of impeller, refers to a kind of blast fan for the automobile heat transmission especially.
Background technique
At present, the heat transmission blast fan that uses in automobile is except air quantity and these two main performance index of noise, also require the intensity of blast fan to reach certain requirement, guarantee the working life of blast fan, and the intensity of blast fan or shape are not up to standard, so fragile blast fan in rotary course, also may reduce simultaneously the air output of blast fan, increased noise, therefore, the intensity of blast fan and the shape of shape also seem particularly important.And generally be to comprise wheel hub for present band blast fan, the outer shroud of ring and several blades, described wheel hub comprises substrate and the tubular portion that is connected with substrate, described substrate is provided with mounting hole, described several blades are arranged between the periphery and outer shroud of tubular portion, the outer shroud thinner thickness of this blast fan, width is narrower, therefore the circularity of outer shroud is difficult to guarantee in forming process, particularly outer shroud be in part between adjacent two blades because just more yielding without any supporting, install that cooperate may inaccuracy, may be uneven thereby stressed during rotation, can reduce air output, increase noise, certainly the working life that also can reduce fan.
The model utility content
Technical problem to be solved in the utility model is: the blast fan that the automobile heat transmission of a kind of intensity height, long service life is provided.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of automobile heat transmission blast fan, the outer shroud and several blades that comprise wheel hub, ring, described wheel hub comprises substrate and the tubular portion that is connected with substrate, described substrate is provided with mounting hole, and described several blades are arranged between the periphery and outer shroud of tubular portion; The axial end of described outer shroud is along being provided with several arc convex sections, and each arc convex Duan Jun is between adjacent two blades, and each arc convex section is along the axial direction projection of outer shroud, and the center of circle of each arc convex section overlaps with the outer shroud center of circle.
As a kind of preferred scheme, described outer shroud comprises that the some sections fixedly segmental arcs that are connected with vanes fixed and some sections of linking to each other with adjacent two holding parts are connected segmental arc, each fixedly segmental arc be connected the outer shroud that segmental arc constitutes described ring, described several arc convex sections are arranged on one to one and respectively connect on the segmental arc, and these several arc convex sections evenly distribute with respect to the center of circle of outer shroud.
As a kind of preferred scheme, the arching trajectory mid point of described each arc convex section overlaps with the track mid point that is connected segmental arc.
As a kind of preferred scheme, the interior edge face of described substrate is provided with several stiffening ribs.
As a kind of preferred scheme, described stiffening rib comprises an annulus stiffening rib and several bar shaped stiffening ribs, this annulus stiffening rib arranges with described mounting hole is concentric, described bar shaped stiffening rib extends to substrate by this annulus stiffening rib and tubular portion intersects on the circle, and this bar shaped stiffening rib is with respect to annulus stiffening rib circumference array.
As a kind of preferred scheme, the intersection point of each bar shaped stiffening rib and annulus stiffening rib all be in the bar shaped stiffening rib with the rotation upstream of the intersection point of described crossing circle.
As a kind of preferred scheme, also be provided with several shaft orientation reinforcing ribs on the inwall of described tubular portion, this shaft orientation reinforcing rib and bar shaped stiffening rib connect one to one.
After having adopted technique scheme, effect of the present utility model is: because the axial end of described outer shroud is along being provided with several arc convex sections, each arc convex Duan Jun is between adjacent two blades, each arc convex section is along the axial direction projection of outer shroud, and the center of circle of each arc convex section overlaps with the outer shroud center of circle.Therefore, this arc convex section has increased intensity to outer shroud, also is that the low partial width of outer shroud intensity is widened, and is not yielding in forming process, and then increases the service life.
Because the arching trajectory mid point of described each arc convex section overlaps with the track mid point that is connected segmental arc, make the increase of connection segmental arc bulk strength more even again, stressed even during the rotation of whole wind Vane wheel, when improving intensity, effectively reduce noise.
Again since the intersection point of each bar shaped stiffening rib and annulus stiffening rib all be in the bar shaped stiffening rib and with the rotation upstream of the intersection point of described crossing circle, therefore, it is longer that the length of the length of bar shaped stiffening rib can arrange, and then farthest increased the intensity of wheel hub.
Owing to also be provided with several shaft orientation reinforcing ribs on the inwall of described tubular portion, this shaft orientation reinforcing rib and bar shaped stiffening rib connect one to one, and have equally further increased intensity again.
