Abstract
A kind of air source heat pump fan, including wheel hub, blade, bearing.The hub centre is connected to motor by bearing, the hub shell is made of composite material, multiple blades are connected with outside circumference of hub, the blade is gradually become smaller by the interior thickness for enclosing periphery, inside enclosing thickness is 1mm, peripheral thickness is 0.5mm, and the fan is provided with fan outline border, and blade windward side front is provided with continuous concave-convex notch；The another side of the blade is arc-shaped, and the blade is made of composite material.Air source heat pump fan is designed using composite air principle of dynamics, and special composite material is made, operation low noise, high-efficient, effectively reduces noise.
Description
Technical field
The present invention relates to a kind of fans, and in particular to a kind of air source heat pump fan.
Background technique
With the development of the society, the development of science and technology, air-conditioning technical is also constantly improving.Due to the shortage of china natural resources, combustion
Material combustion heat supplying system waste a large amount of energy again, also can cause environmental pollution, air source heat pump heat it is few with its initial cost,
Without huge occupied area, convenient to install and maintain, energy conservation and environmental protection, the higher advantage of efficiency, the approval in market is gradually obtained, and
National policy is obtained more and more to support and promote.Air source heat pump fan is used for the discharge of heat pump internal heat.Existing sky
After a period of use, due to bearing wear, flabellum deviates bearing centre to air supply heat pump fan, and vibration generates biggish noise；
Simultaneously as flabellum rotate when and windage, can also generate certain noise.Solve the noise of existing air source heat pump fan
Problem is those skilled in the art's urgent problem to be solved.
Summary of the invention
In order to solve the above technical problem, the present invention provides a kind of air source heat pump fans.
The technical scheme adopted by the invention is that：A kind of air source heat pump fan, including wheel hub, blade, bearing, fan
Outline border.The hub centre is connected to motor by bearing, and the hub shell is made of composite material, the outer activity of circumference of hub
Multiple blades are connected with, the blade is gradually become smaller by the interior thickness for enclosing periphery, and inside enclosing thickness is 1mm, and peripheral thickness is 0.5mm,
The fan is provided with fan outline border；
Further, blade windward side front is provided with continuous concave-convex notch；
Further, the another side of the blade is arc-shaped；
Further, the blade is made of special composite material.
The invention has the advantages that a kind of air source heat pump fan is designed using composite air principle of dynamics, blade
It is made of special composite material, operation low noise, high-efficient effectively reduces noise.
Detailed description of the invention
Fig. 1 is overall structure structural schematic diagram of the invention.
In figure, 1：Wheel hub；2 ：Bearing；3 ：Blade；4 ：It is enclosed in blade；5 ：Blade periphery；6：Fan outline border.
Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and examples.
A kind of air source heat pump fan, including wheel hub 1, bearing 2, blade 3.1 center of wheel hub passes through bearing 2 and motor
Connection, 1 shell of wheel hub is made of composite material, is connected with multiple blades 3 outside 1 circumference of wheel hub, and the blade 3 is by interior
The thickness for enclosing 4 to periphery 5 gradually becomes smaller, and inside enclosing 4 thickness is 1mm, and peripheral 5 thickness are 0.5mm, and the fan is provided with fan outline border 6,
Further, the 3 windward side front of blade is provided with continuous concave-convex notch；Further, the another side of the blade 3 is
Arc-shaped；Further, the blade 3 is made of special composite material.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
In the technical scope disclosed by the present invention, any changes or substitutions that can be easily thought of by anyone skilled in the art,
It should be covered by the scope of protection of the present invention.Therefore, protection scope of the present invention should be with the protection scope of claims
Subject to.
