For this reason, artificer of the present invention is because above-mentioned defect, and by concentrating on studies and designing, comprehensive experience and the achievement being engaged in related industry for a long time for many years, research and design goes out a kind of cooling fan with feeler mechanism, to overcome above-mentioned defect.
Summary of the invention
The technical problem to be solved in the present invention is: existing cooling fan, structure relative complex, and cost is higher, easily causes installation location difficulty, and is not with detection device, is difficult to obtain testing signal accurately, has necessity of improvement in fact.
For solving the problem, the invention discloses a kind of cooling fan with feeler mechanism, comprising base, flabellum shell, rotor and stator; It is characterized in that:
Described base is square framework, has circular groove in the middle part of it, and the center of described circular groove has cylindric positioning seat, is provided with positioning hole in described positioning seat;
Described stator is fixed in circular groove, and it is wound with by polylith, and the steel disc of coil is stacked to be formed, and is provided with a through hole passed for described positioning seat in the middle part of it, spaced apart to form a rotor accommodating part between described through hole and positioning seat;
Described flabellum shell comprises discoid base plate and from the outward extending annulus of base portion peripheral, the positioning rod that described positioning hole is stretched in an activity is extended at the center of described base plate, and described annulus stretches into described circular groove and is positioned at the outside of described stator;
Described rotor is fixed on the base plate of described flabellum shell and is positioned at described rotor accommodating part when positioning rod stretches into described positioning hole;
Also include feeler mechanism, described feeler mechanism comprises the detected element that is positioned at described rotor bottom and is fixed on described base and the sense cell that arranges of corresponding described detected element.
Wherein: the outer periphery of described annulus are fixed with the flabellum that multi-disc is obliquely installed.
Wherein: described sense cell is fixed on a mounting circular ring, and described mounting circular ring is fixed on base by multiple bolt.
Wherein: multiple bolt runs through described stator and is fixed on described base to be fixed in the circular groove of described base by described stator.
Known by said structure, the cooling fan structure with feeler mechanism of the present invention is simple, easy for installation, can rotate and detect, thus can obtain signal in time, avoid fan fails to cause wafer damage to fan.
Detailed content of the present invention obtains by explanation described later and institute's accompanying drawing.
Accompanying drawing explanation
Fig. 1 shows the structural representation that the present invention has the cooling fan of feeler mechanism.
Fig. 2 shows the sectional view that the present invention has the cooling fan of feeler mechanism.
Embodiment
See Fig. 1 and Fig. 2, show the cooling fan with feeler mechanism of the present invention.
The described cooling fan with feeler mechanism comprises base 21, flabellum shell 22, rotor 23 and stator 24.
Wherein, described base 21 is square framework, has circular groove in the middle part of it, and the center of groove has cylindric positioning seat, is provided with positioning hole in described positioning seat.
Described stator 24 is fixed in described circular groove, it is wound with by polylith, and the steel disc 241 of coil 242 is stacked to be formed, a through hole passed for described positioning seat is provided with in the middle part of it, spaced apart to form a rotor accommodating part between described through hole and positioning seat, and multiple bolt 243, described bolt 243 runs through described stator 24 and is fixed on described base 21, thus is fixed on by described stator 24 in the circular groove of described base 21.
Described flabellum shell 22 comprises discoid base plate and from the outward extending annulus of base portion peripheral, thus, described flabellum shell 22 forms inner circular containing space, the positioning rod that described positioning hole is stretched in an activity is extended at the center of described base plate, described annulus stretches into described circular groove and is positioned at the outside of described stator 24, and the outer periphery of described annulus are fixed with the flabellum 25 that multi-disc is obliquely installed.
Described rotor 23 is fixed on the base plate of described flabellum shell 22 and is positioned at described rotor accommodating part when positioning rod stretches into described positioning hole, thus, by giving the coil power supply of stator, can drive rotor turns, and then drives flabellum to rotate, for chip brings cooled flow.
Wherein, for improving intensity, described base 21, flabellum shell 22 are made by phenolic resin.
Detect for carrying out rotation, described chip cooling technique fan also comprises feeler mechanism, described feeler mechanism comprises the detected element 32 that is positioned at bottom described rotor 23 and is fixed on described base 21 and the sense cell 33 that arranges of corresponding described detected element 32, described sense cell 33 is fixed on a mounting circular ring 31, and described mounting circular ring 31 is fixed on base 21 by multiple bolt 34.
Thus, when flabellum rotates, described sense cell 33 effectively can detect the rotation of described detected element 32, thus obtains a testing signal.
Wherein, described sense cell 33 and coil 242 are also connected to a control unit with reception control signal and transmission testing signal, and described control unit is also provided with an alarm unit carrying out when deviation appears in testing signal and control signal reporting to the police.
Known by said structure, the cooling fan structure with feeler mechanism of the present invention is simple, easy for installation, can rotate and detect, thus can obtain signal in time, avoid fan fails to cause wafer damage to fan.
It is evident that, above description and record be only citing instead of in order to limit disclosure of the present invention, application or use.Although described in an embodiment and be described in the drawings embodiment, but the present invention do not limit by accompanying drawing example and describe in an embodiment as the optimal mode thought at present to implement the specific examples of instruction of the present invention, scope of the present invention will comprise any embodiment of specification and the appended claim fallen into above.
