Background technique
Radiator fan generally refers to also set for mainboard devices cooling fan, some of radiator fans such as CPU, video cards
There is cooling fin, main purpose is to achieve the effect that cooling in the air near transferring out to come heat and blowing in fact.It is above-mentioned
Such radiator fan is also widely used in the metal cabinet doors such as cabinet, power control cabinet, does not need heat radiating fin structure generally.Mesh
Before, high-performance small size is radiator fan development trend, makes motor temperature rise excessively high from thermal diffusivity deficiency because of fan motor, existing
There is radiator fan to achieve the effect that reduce temperature rise by replacing more advanced components or increase motor size mostly；To
Cause cost sharply to increase, limits the further promotion of fan performance.Other similar radiator fans are dropped by cooling structure
The temperature of low motor, higher cost, structure are complex.
Summary of the invention
To overcome above-mentioned deficiency, the purpose of this utility model is that a kind of active of radiator fan motor inside is provided to this field
Cooling mechanism makes it solve existing similar product and lacks simple heat radiation structure design or heat radiation structure design higher cost, ties
The complex technical problem of structure.The purpose is to what is be achieved through the following technical solutions.
A kind of radiator fan motor inside active heat removal mechanism, which includes frame, motor, fan body, institute
It states and is equipped with circuit board in frame, circuit board is linked together with motor；Its structure designing points is that the circuit board is set to motor
End face side, the top of circuit board is equipped with heat source body, and heat source body is the heating electronic component of circuit board, the hollow out muscle of frame
Side central ring face is equipped with medium through hole, and heat eliminating medium is set in the medium through hole of frame, the heat of heat eliminating medium and circuit board
Source body abuts.It is above-mentioned that the space for placing heat eliminating medium is reserved in cooling fan structure design, so that heat eliminating medium is close
Or the heat source of radiator fan internal circuit board is attached, so that actively export radiates out by heat, heat eliminating medium is metalwork.
And the volume for not increasing radiator fan is changed without on the basis of the electronic component of motor and achievees the purpose that reduce temperature rise, makes
Obtain the performance boost of radiator fan.
The central axis of the frame is equipped with metal axle sleeve, and frame and motor are linked together by metal axle sleeve, metal axle sleeve
Axle sleeve circle face and the central ring face paste of frame close, the axle sleeve circle face of heat eliminating medium and metal axle sleeve abuts.Above-mentioned is scattered
Thermal medium is in such a way that metal axle sleeve exports heat, i.e., in such a way that other components transfer out heat.
The heat source body of the circuit board is circuit board thermal conductive medium, and circuit board thermal conductive medium passes through the silicon of circuit board and motor
Steel disc contact.To which the heat of motor further be exported by circuit board thermal conductive medium, heat eliminating medium.
The structure design of the utility model is reasonable, and long service life, production cost is low, and stability is good, cooling, heat dissipation effect
It is good；It is suitable as in radiator fan active heat radiation structure inside motor and uses, ex hoc genus anne the structure of product improve.

Axle sleeve.
Specific embodiment
Now in conjunction with attached drawing, the utility model structure and use are further described.Embodiment one as shown in Figure 1 and Figure 2,
The active heat removal mechanism includes frame 1, motor 2, fan body, is equipped with circuit board 201 in frame, circuit board is linked together with motor.
Specifically: circuit board is set to the end face side of motor, and the top of circuit board is equipped with heat source body 202, and heat source body is circuit board
The hollow out muscle side central ring face of heating electronic component, frame is equipped with medium through hole, and heat eliminating medium 3 is set to the medium of frame
In through-hole, the heat source body of heat eliminating medium and circuit board is abutted.The electronics of heat is easy to produce in above structure on circuit board
Component can directly be radiated by heat eliminating medium goes out with thermally conductive, to further decrease the heat and motor of circuit board
The heat of generation.
Embodiment two as shown in Figure 3, the central axis of frame are equipped with axle sleeve, and axle sleeve uses metal axle sleeve 4, and frame and motor are logical
It crosses metal axle sleeve to be linked together, the axle sleeve circle face of metal axle sleeve and the central ring face paste of frame are closed, heat eliminating medium and metal axle sleeve
Axle sleeve circle face abut.Above-mentioned motor is motor stator, by the metal axle sleeve with heating conduction in above structure,
Not only it can be convenient for for heat eliminating medium being fixed in frame, but also be able to achieve its thermally conductive and heat dissipation purpose.
According to above structure feature and working principle, further, the heat source body of circuit board is set as circuit board thermal conductive Jie
Matter, circuit board thermal conductive medium are contacted by circuit board with the silicon steel sheet of motor, so that indirectly technological means and technical approach will
Heat in motor further exports.
In conclusion the utility model adds the heat eliminating medium of auxiliary heat dissipation on the basis of original motor, to realize master
Dynamic heat dissipation reaches the effect for reducing heat source temperature rise in radiator fan.
