Technical field
The invention belongs to Compressor Technology field, relate to a kind of structure of cooling fan, relate in particular to a kind of possess simultaneously have the compound blade structure fan of centrifugal fan and axial flow fan character and the compressor with this fan.
Background technique
Existing fan, principal mode is shaft flow structure and centrifugal structure, and the former utilizes the axial-flow leaf of rotation to produce mainly along fan rotational axis direction mobile axial flow, the latter to utilize the radially fan blade of rotation to produce main radially mobile centrifugal flow.
But in some occasion, usually need a fan can produce axial flow and radial air flow simultaneously.As oil-free air compressor just needs the cylinder cap of cooling air cylinder head and the main bearing of support bent axle simultaneously, because cylinder cap is generally arranged in by a side that departs from compressor rotational axis, therefore need centrifugal fan to produce radial air flow and blow to these parts to carry out cooling to it, in addition because main bearing is generally sleeved on the bent axle of compressor, therefore need fan to produce axial flow in addition cooling to main bearing.Obviously, traditional centrifugal fan or axial flow fan all can not meet above-mentioned job requirement.
Summary of the invention
The deficiency existing for existing cooling fan and with the compressor of these cooling fans, the invention provides a kind of combination type fan, and object is to produce reliably radial air flow and axial flow simultaneously; The present invention also provides the compressor with this combination type fan, and object is the cylinder head of cooling compressor and the main bearing of compressor simultaneously, thereby effectively improves the functional reliability of compressor.
For achieving the above object, the invention provides a kind of combination type fan, it is characterized in that: fan is provided with runoff blade and axial blade, when described runoff blade rotary, can derive radial air flow, when described axial blade rotation, can derive axial flow.
Between above-mentioned runoff blade and axial blade, be provided with isolation endless belt, runoff blade along the revolution circumference directional ring cloth of fan in the outside of isolation endless belt, axial blade along the revolution circumference directional ring cloth of fan the inner side at isolation endless belt.
Above-mentioned runoff blade is dislocation layout with respect to axial blade along the rotational axis direction of fan.
Above-mentioned axial blade adopts runoff blade structure, and is combined into axial flow fan with isolation endless belt.
To achieve these goals, the present invention also provides a kind of compressor with composite fan, it is characterized in that: compressor configuration has air guide sleeve, and the air-flow that described air guide sleeve produces composite fan runoff blade guides to the cylinder head position of compressor.
A kind of combination type fan of the present invention and with the compressor of this fan, because employing is compounded with the structure of runoff blade and axial blade, thereby can produce centrifugal radial air flow and the axial flow of axial flow simultaneously, cylinder head to compressor and main bearing carry out effective cooling simultaneously accordingly, have ensured the functional reliability of compressor.

Embodiment
With specific embodiment, the invention will be further described below, referring to Fig. 1-9:
A kind of combination type fan, be with existing fan difference: this fan is provided with runoff blade 1 and axial blade 2 (as shown in Figures 1 to 9), described runoff blade 1 can derive centrifugal radial air flow while rotation, and described axial blade 2 can derive the axial flow of axial flow while rotation.Because fan of the present invention adopts the structure that is compounded with runoff blade 1 and axial blade 2, therefore can produce the axial flow B (as shown in Figure 9) of centrifugal radial air flow A and axial flow simultaneously, therefore can carry out effective cooling to cylinder head 3 (as shown in Figure 9) and the main bearing (not shown) of compressor simultaneously, ensure the functional reliability of compressor.
For fear of the mutual interference of air-flow phase, fan of the present invention can arrange isolation endless belt 4 (referring to Fig. 1 to Fig. 9) between runoff blade 1 and axial blade 2, wherein runoff blade 1 along the revolution circumference directional ring cloth of fan in the outside of isolation endless belt 4, axial blade 2 in the inner side of isolation endless belt 4, like this can amplitude peak ground reduces the phase mutual interference of the air-flow that above-mentioned two kinds of blades derive from along the revolution circumference directional ring cloth of fan; It is pointed out that by designing and adjusting and isolate the placement position of endless belt and towards attitude, can allocate as required the flow proportional of radial air flow A and axial flow B.
For layout flexible, runoff blade 1 of the present invention can present dislocation layout with respect to axial blade 2 along the direction of fan rotational axis O, be that the set of plane of rotation of runoff blade 1 whole Component units and the set of the plane of rotation of axial blade 2 whole Component units can be unequal, in other words there is nonoverlapping position at axial direction in both, and the projection of runoff blade 1 on fan rotational axis O in other words exists with the projection of axial blade 2 on fan rotational axis O the phenomenon not overlapping; Certainly, runoff blade 1 also can overlap in full accord in other words with the projection of axial blade 2 on fan rotational axis O completely.
For simplified structure, the axial blade 2 of fan of the present invention can adopt the structural form of runoff blade 1, and be combined into axial flow fan (referring to Fig. 5 to Fig. 8) with isolation endless belt 4, now in the time that axial blade 2 rotates, it will produce centrifugal flow, and this centrifugal flow is converted into axial flow air-flow under the guiding of isolation endless belt 4; It should be noted that, axial blade 2 can be the part structure (referring to Fig. 5 to Fig. 8) of runoff blade 1.
The present invention also provides a kind of compressor (as shown in Figure 9) with composite fan, its characteristic is: compressor configuration has air guide sleeve 5, the radial air flow A that described air guide sleeve 5 produces composite fan runoff blade 1 guides to the cylinder head 3 of compressor and implements cooling to this position, meanwhile, the axial blade 2 of composite fan produces the axial flow B of axial flow and is directed to the main bearing place of compressor, thereby it is enough cooling that main bearing is obtained.
A kind of combination type fan of the present invention and with the compressor of this fan, because employing is compounded with the structure of runoff blade 1 and axial blade 2, thereby can produce centrifugal radial air flow A and the axial flow B of axial flow simultaneously, cylinder head 3 to compressor and main bearing carry out effective cooling simultaneously accordingly, ensured the functional reliability of compressor, described combination type fan is driven by the line shaft of compressor.
Above-described embodiment is only some preferred embodiments of the present invention, not limits the scope of the invention according to this, therefore: all various equivalences of doing according to structure of the present invention, shape, principle change, within all should being encompassed in protection scope of the present invention.
