Description
Technical field
The present invention relates to the cooling apparatus field of electric appliance component, specifically a kind of double-deck centrifugal fan.
Background technique
In the prior art, small-sized cooling radiator fan is because of itself smaller, lighter in weight, and the weight of fan itself is to electricity
The influence of machine is not it is obvious that the power of motor and temperature rise will not be significantly affected.And large and medium-sized fan, because its
Body structure is larger, and weight is larger, and the weight with regard to many thousands of gram, is affected to the performance of motor easily, the temperature rise of motor
It can therefore improve.When motor operation, the power of output is bigger, then electric current and loss are bigger, and temperature is higher, and motor is for a long time in height
When being operated under warm environment, may result in the physics of insulating materials, machinery, chemistry and electric property occur significant severe variation or
Cause quick aging, so that the reduced service life and input power of motor are higher, influences the energy consumption of complete machine.And existing electric appliance
The adjacent small space of group there are problems that larger cooling fan can not be placed, cause the service life of electric appliance component short and exist
Other security risks.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the existing defects, and providing one kind, work efficiency is high, space utilization rate
The double-deck centrifugal fan that is higher, saving power consumption.
In order to solve the above-mentioned technical problems, the present invention provides the following technical solutions:
A kind of bilayer centrifugal fan, including shell and flabellum, the flabellum include major diameter flabellum and path flabellum, described big
Diameter flabellum be equipped with the first fixed station, big flabellum skeleton and the first fixed shaft hole, the path flabellum be equipped with the second fixed station,
The inside of small flabellum skeleton and the second fixed shaft hole, the shell is equipped with central axis, and the major diameter flabellum and path flabellum pass through
Central axis is connected together up and down, the central axis run through the first fixed shaft hole and the second fixed shaft hole, the major diameter flabellum and
Path flabellum passes through the first fixed station and the second fixed station fixed center axis.
Further, the outside of the central axis is equipped with copper bush, is fixed with installation on the outside of the upper end of copper shaft set
Frame.
Further, the middle lower end of copper shaft set is equipped with silicon steel sheet, and the outside vertical of the silicon steel sheet is equipped with magnet block.
Further, the lower section of the mounting rack is equipped with wiring board.
A kind of double-deck centrifugal fan of the present invention, major diameter flabellum and path flabellum are arranged on mounting rack, passes through two flabellums
Cooperation solve the problems, such as the ventilation and heat inside electric appliance component.The rotation fortune of central axis is driven by a motor drive component
Make, come solve the problems, such as two adjacent small spaces electric elements cooling, while saving power consumption.Present invention is mainly used for
The optimization in the space, quality, power of Aeronautics and Astronautics equipment, reaches energy-saving effect, and the space utilization of enlarged component reduces component
Total quality.
Detailed description of the invention
Attached drawing is used to provide further understanding of the present invention, and constitutes part of specification, with reality of the invention
It applies example to be used to explain the present invention together, not be construed as limiting the invention.In the accompanying drawings:
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is flabellum schematic diagram of the invention；

Specific embodiment
Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings, it should be understood that preferred reality described herein
Apply example only for the purpose of illustrating and explaining the present invention and is not intended to limit the present invention.
As Figure 1-Figure 4, a kind of double-deck centrifugal fan of the present invention, including shell 1 and flabellum 2, the flabellum 2 include big
Diameter flabellum 21 and path flabellum 22, it is solid that the major diameter flabellum 21 is equipped with the first fixed station 211, big flabellum skeleton 212 and first
Dead axle hole 213, the path flabellum 22 are equipped with the second fixed station 221, small flabellum skeleton 222 and the second fixed shaft hole 223, institute
The inside for stating shell 1 is equipped with central axis, the major diameter flabellum 21 and path flabellum 22 and is connected together up and down by central axis, institute
Central axis is stated through the first fixed shaft hole 213 and the second fixed shaft hole 223, the major diameter flabellum 21 and path flabellum 22 pass through the
221 fixed center axis of one fixed station 211 and the second fixed station.The outside of the central axis is equipped with copper bush, copper shaft set
Mounting rack is fixed on the outside of upper end.The middle lower end of copper shaft set is equipped with silicon steel sheet, and the outside vertical of the silicon steel sheet is equipped with
