Description
Technical field
The utility model relates to a kind of split labyrinth type fan wind shelling cover assembly, belongs to a kind of assembly parts of new structure, is applied to automobile or other cooling system technical field.
Background technique
Labyrinth type fan wind shelling cover assembly heavy type commercial truck assemble in annular air bike type use comparatively extensive.At present, this labyrinth type fan wind shelling cover assembly is monolithic construction, when vehicle is designed and developed, the integrated fan wind shelling cover assembly that different automobile types is different with a cooling system and engine location, throw of eccentric just need to be designed and developed new corresponding throw of eccentric when different, various just need to drop into many molds, makes enterprise increase great amount of cost input; If mold does not adopt the method manufactures such as steel plate butt welding to have the shortcomings such as manufacturing process is many, the time is long, product price is high, difficult quality guarantee.
Summary of the invention
The purpose of this utility model is to provide a kind of split labyrinth type fan wind shelling cover assembly, it forms multiple different fan cowl assembly by adjusting fan guard center from the throw of eccentric at wind shelling cover body center, realize the object of the whole labyrinth type fan wind shelling cover of the many moneys of a kind of products substitution assembly, can reduce in a large number number of molds, reduce entreprise cost input.
The technical solution of the utility model is achieved in that a kind of split labyrinth type fan wind shelling cover assembly, by fan cowl body and labyrinth guard ring, formed, it is characterized in that: the disalignment of the center line of fan cowl body and labyrinth guard ring is called assembly throw of eccentric, the distance X span of assembly throw of eccentric is between ± 60mm, corner of end face of fan cowl body has a positioning hole, other edges of fan cowl body end face and corner are evenly distributed with 4～10 oval attachment holes, oval attachment hole is divided into two groups, the slotted hole of one group is horizontal, the slotted hole of another group is vertical direction, on fan cowl body bottom surface, lower limb has Stamping Steel Ribbon, the position that connects labyrinth guard ring on fan cowl body end face has the adjusting hole of 4～8 groups, every group of adjusting hole is 1～3 round, every row is comprised of 3～8 holes, on the guard ring of labyrinth, have spacing hole, labyrinth guard ring passes spacing hole by bolt and is fixedly connected with the adjusting hole of fan cowl body, and heat exchanger assembly is fixedly connected with the bottom surface of fan cowl body.
Good effect of the present utility model is that it forms multiple different fan cowl assembly by adjusting fan guard center from the throw of eccentric at wind shelling cover body center, realize the object of the whole labyrinth type fan wind shelling cover of the many moneys of a kind of products substitution assembly, can reduce in a large number number of molds, reduce entreprise cost input.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail: as Fig. 1, 2, shown in 3, a kind of split labyrinth type fan wind shelling cover assembly, by fan cowl body 1 and labyrinth guard ring 2, formed, it is characterized in that: the disalignment of the center line of fan cowl body 1 and labyrinth guard ring 2 is called assembly throw of eccentric, the distance X span of assembly throw of eccentric is between ± 60mm, corner of end face of fan cowl body 1 has a positioning hole 6, other edges of fan cowl body 1 end face and corner are evenly distributed with 4～10 oval attachment holes 7, oval attachment hole 7 is divided into two groups, the slotted hole of one group is horizontal, the slotted hole of another group is vertical direction, on fan cowl body 1 bottom surface, lower limb has Stamping Steel Ribbon 8, the position that connects labyrinth guard ring 2 on fan cowl body 1 end face has the adjusting hole 4 of 4～8 groups, every group of adjusting hole 4 is 1～3 round, every row is comprised of 3～8 holes, on labyrinth guard ring 2, have spacing hole 5, labyrinth guard ring 2 is by alternate manners such as bolt 3(or rivets) through spacing hole 5, be fixedly connected with the adjusting hole 4 of fan cowl body 1, heat exchanger assembly 10 is fixedly connected with the bottom surface of fan cowl body 1, ring-type fan 11 forms assembly relation as shown in Fig. 5 the utility model System Working Principle figure with labyrinth guard ring 2 after car load assembling.
As shown in Figure 3,4: the adjusting hole 4 on the ear end face of fan cowl body 1 designs in advance, by 4～8 groups of holes, formed, every group of adjusting hole is provided with 1～3 round, every round is comprised of 3～8 holes, when assembly is produced, manufacturer installs corresponding hole bit location according to throw of eccentric X value in fan cowl body mold, adjusting hole on the bit location of hole is only chosen the position, hole that 1 place is suitable for throw of eccentric X, and other position, hole does not need open-minded; When fan cowl body mold is during for the production of another throw of eccentric assembly, the hole bit location of the replaceable correspondence of manufacturer, all the other positions, hole (position, hole of using before comprising) do not need open-minded.By the adjustment of pre-designed adjusting hole 4 and corresponding hole site unit, combine like this, can realize the object that a mold is produced the split labyrinth type fan wind shelling cover assembly that multiple throw of eccentric is different.
As shown in Figure 5, connecting bolt 9 is fixed on assembly above heat exchanger assembly 10 by split labyrinth type fan wind shelling cover assembly body 1 positioning hole 6 and oval attachment hole 7 above; When car load has assembled, the outer shroud of ring-type fan 11 can enter in labyrinth guard ring 2 " U " type maze trough, when ring-type fan 11 High Rotation Speed, make fan blade produce negative pressure around, large quantity of air, at the dirty over-heat-exchanger assembly 10 of pressure difference effect, flows to ring-type fan 11 rears after the split labyrinth type fan wind shelling cover assembly of flowing through; " U " type maze trough of a small amount of air interannular from labyrinth guard ring 2, ring-type fan 11 flows out, because labyrinth guard ring 2 is air resistances that " U " type maze trough structure can increase the air of flowing through, the loss air of " U " type maze trough of making to flow through reduces in a large number, thereby that has improved split labyrinth type fan wind shelling cover assembly protects wind effect, therefore, it is few that this split labyrinth type fan wind shelling cover assembly has the air loss of flowing through, and protects the effective advantage of wind.
