Said structure feature can make to form the path being similar to labyrinth between the annular sidewall in the extension part of bearing structure and impeller or fan hub portion, at least significantly can reduce described motor and be exposed in etching reagent/oxygenant.
As a kind of preferred version, the annular sidewall in impeller or fan hub portion is positioned at the inner side of the extension part of bearing structure.
A second aspect of the present invention also provides a kind of heat exchanger applying above-mentioned ventilation plant.
As a kind of preferred version, the fan of described heat exchanger, radiator lay respectively at the two ends of described stator.
Below in conjunction with accompanying drawing, more structure characteristics of the present invention and advantage are further described, but embodiments of the present invention are not limited thereto.
[accompanying drawing explanation]
Below in conjunction with Figure of description and embodiment, the invention will be further described.In Figure of description, same structure, element or parts use identical figure notation usually.Between each assembly, size relationship is normally in order to show better, not necessarily requires that each assembly is according to this kind of size relation.
Fig. 1 is the perspective view of the part-structure of ventilation plant provided by the invention;
Fig. 2 is the sectional view of the ventilation plant shown in Fig. 1.
[embodiment]
In the accompanying drawings, label 1 represents ventilation plant provided by the invention, and this ventilation plant can be used for the heat exchanger of Motor Vehicle, the radiator of such as Motor Vehicle.
Ventilation plant 1 comprises bearing structure 2 (in Fig. 1), and this bearing structure 2 plays fixing effect.
Bearing structure 2 comprises the annular support member 5 in housing 3, housing 3 and connects multiple spokes 4 (as shown in Figure 1) of described housing 3 and annular support member 5.
As shown in Figure 2, ventilation plant 1 also comprises direct current generator 6, and such as, this direct current generator 6 is brushless electric machines 6, and comprise the inner stator 7 being installed on annular support member 5 and the external rotor 8 being looped around inner stator 7 periphery, external rotor 8 has some permanent magnets.
Direct current generator 6 comprises corresponding electronic control circuit 9 (in Fig. 2), the element 10 of this electronic control circuit 9 is installed on circuit board 12, this circuit board 12 can and the radiator 11 of template between carry out heat exchange, radiator 11 is relative to the central axis A-A cross setting of direct current generator 6.
Ventilation plant 1 also comprises impeller or fan 20, and this fan 20 is fixedly installed on the rotor 8 of direct current generator 6, and fan 20 and radiator 11 lay respectively at the axial two ends of stator 7.
As shown in Figure 1, fan 20 comprises multiple blades 14 that the hub portion 13 of hollow and loose boss portion 13 extend radially outward, and the radial outer end of blade 14 is connected to a ring body 15, and ring body 15 is positioned at annular opening 15 place of the housing 13 of bearing structure 2.
Hub portion 13 has antetheca 13a (as shown in Figure 2), and described antetheca 13a is subject to the effect of the air-flow produced when fan 20 works.
Described hub portion 13 also comprises the sidewall 13b being similar to annular, and this sidewall forms annular motor host cavity around the periphery of motor.
As shown in Figure 2, the annular support member 5 of bearing structure 2 has the extension part 5a being similar to annular, and described extension part 5a extends towards the hub portion 13 of fan 20 in the axial direction.
Preferably, the extension part 5a of supporting element 5 is coaxial with the central axis A-A of direct current generator 6, and is positioned at the radial outside of annular sidewall 13b.Understandably, tilt a little situation of (inclinations as within 30 degree) of the central axis A-A of the relative motor 6 of extension part 5a also belongs to the situation being similar to annular herein.
As shown in Figure 2, there is the mutually interspersed and overlapping of part with the annular sidewall 13b in hub portion 13 in the extension part 5a of supporting element 5, namely along mutually interspersed and overlapping on the direction of the central axis A-A of motor 6 in axial direction.
In the present embodiment, this kind of mode of execution can realize being because the sidewall 13b in hub the portion 13 and extension part 5a of supporting element 5 has wall body or prolonged section 13c and 5b of extension respectively, preferably, and this prolonged section 13c and 5b molding and forming.
In Fig. 2, prolonged section 13c and 5b is the additional of the extension part 5a of the supporting element 5 and annular sidewall 13b in hub portion 13 or extension respectively, but, this kind of describing mode is only used to the increase that the length that described extension part and described annular sidewall are in axial direction gone up is described, in fact, manufacture fan process in, prolonged section 13c and 5b can respectively with hub portion 13 and supporting element 5 one-body molded; Certainly, also can hub portion 13 and supporting element 5 shaping after again prolonged section 13c and 5b is mounted on hub portion 13 and supporting element 5.
Because etching reagent/oxygenant has potential corrosion to motor 6, the structural design that hub portion 13 and supporting element 5 intert in the axial direction is mutually the path that etching reagent/oxygenant provides approximate labyrinth, add the difficulty that etching reagent/oxygenant enters motor internal, thus the infringement that etching reagent/oxygenant produces motor can be reduced.
This kind of structural design can reduce the conservation treatment to motor 6 metallic member, thus cost-saving.
These are only the preferred embodiments of the present invention, under the prerequisite not departing from conception principle of the present invention, some distortion and improvement can also be made, therefore according to the equivalent variations that the present patent application the scope of the claims is done, still belong to the scope that the present invention is contained.
