Abstract
The utility model discloses a motor heat radiator, and the motor comprises a stator and a rotor. The utility model is characterized in that the rotor is provided with a hub, a hub is provided with a flute, and the inner wall of the flute is provided with a plurality of venting holes. The motor is a DC motor, the rotor also comprises a blade and a magnetic loop, the blade is connected with the hub, the magnetic loop is hidden in the hub and is abutted with the bottom edge of the flute, and the venting holes can radiate the heat of the stator.
Description
The utility model relates to a kind of heat abstractor of motor, and this heat abstractor is in order to increase the heat-sinking capability of motor stator.
The use of DC fan is more and more general, does not almost have institute and lose in electric equipment products.For example in the power supply unit of computer, promptly there is a fan to be used for the high temperature that power supply unit inside is produced is dispelled the heat.Again for example, at the central processing unit of motherboard, promptly have one to be used for fan that central processing unit is dispelled the heat specially.
The too high performance of electric equipment products that will make of temperature reduces, and has destructive power even, and greatly reduced the service life of electric equipment products.Therefore, keeping operating electrical equipment is the task that radiator fan is duty-bound under a room temperature state.
Yet radiator fan no doubt is to dispel the heat to other electronic components, but if the temperature of himself is too high, then be as good as and pour oil on the fire, to the electronic component of heating can not fully be dispelled the heat, moreover itself also may be because of under the hot soak condition, and the life-span shortens.
The pyrotoxin of fan motor is generally from coil on the stator and control circuit.On the radiator fan of general electric equipment products, but lose the device that the coil on the motor stator or control apparatus are dispelled the heat is arranged specially.The size of motor can influence the quality of fan performance usually, and under certain conditions, we wish that fan will have very big flow, and simultaneously, we may wish that size is smaller.But motor too hour, and the motor coil temperature can be too high, therefore, must take the measure of a heat radiation to stator coil, reduces the temperature of coil.
The purpose of this utility model is promptly at the defective of above-mentioned prior art, proposing one can be at the device of motor stator heat radiation, make radiator fan when other heat-generating electronic elements are dispelled the heat, also can give self-radiating, and then make the ILS of radiator fan.
For achieving the above object, the utility model proposes a kind of heat abstractor of motor, this motor comprises a stator and a rotor, and its key is, this rotor tool one wheel hub (hub), and mask one groove on this wheel hub, the groove inwall is provided with a plurality of air vent holes.
The heat abstractor of aforesaid motor, wherein this motor is a direct current motor.
The heat abstractor of aforesaid motor, wherein this rotor also comprises a flabellum and a magnet ring.
The heat abstractor of aforesaid motor, wherein this flabellum is to be connected to this wheel hub.
The heat abstractor of aforesaid motor, wherein this magnet ring is to be hidden in this wheel hub, and withstands the base of this groove.
The heat abstractor of aforesaid motor, wherein said pore are so as to this stator is dispelled the heat.
Below in conjunction with accompanying drawing shown in the embodiment the utility model is described in further detail.
Fig. 1 is the exploded view of the utility model preferred embodiment;
Fig. 2 is flabellum (rotor portion) schematic diagram of another angle of the utility model preferred embodiment.
See figures.1.and.2, it is respectively the three-dimensional exploded view of fan propeller 1 and stator 2, and the flabellum of another angle (rotor portion) schematic diagram.Stator 2 has comprised pedestal 3, iron core 4, coil 5 and circuit board 6, and the circuit of control motor is arranged on circuit board 6, makes the motor rotation.Rotor 1 has comprised a wheel hub 7, mask one groove 8 on this wheel hub 7, and the groove inwall is provided with a plurality of air vent holes 9.The blade of wheel hub 7 outside wind-receiving fans, inside have a magnet ring 10.The magnetic field interaction that the magnetic field of magnet ring 10 and stator 2 are produced can make rotor 1 rotate, and then the blade that drives wheel hub 7 and join with wheel hub 7, produces wind, reaches the purpose to the heat-generating electronic elements heat radiation.
In the prior art, the not action that the heat that stator produced is dispelled the heat, and in the utility model, then can dispel the heat by the heat that pore 9 comes stator is produced.When fan rotated, pore 9 can produce convection current with the air gap that just had originally around the stator, the cold air of outside is brought into or the hot-air of inside is taken out of, made the heat of stator interior be able to dissipation and went out, and then reach purpose to the stator heat radiation.
At the design of pore 9, consider problems such as dust pollution, so design a groove around the wheel hub, pore is hidden in the inboard of groove, the design of concealed pore can make air when convection current, and the probability that sucks dust greatly reduces.
The purpose of this utility model is promptly at the defective of above-mentioned prior art, propose a kind of can be at the device of motor stator heat radiation, make radiator fan when other heat-generating electronic elements are dispelled the heat, also can give self-radiating, and then make the ILS of radiator fan.
This rotor tool one wheel hub that is characterised in that of the present utility model, mask one groove on this wheel hub, the groove inwall is provided with a plurality of air vent holes, can produce the convection current of air thus when motor rotates, and the thermal source of stator interior is dissipated.Because the function of heat radiation that the stator of motor inside is many, thus to the lifting of motor life with helpful.
Technically, this motor is to be a direct current motor, and this rotor also comprises a flabellum and a magnet ring, and this flabellum is connected to this wheel hub, and this magnet ring is hidden in this wheel hub, and withstands the base of this groove, and described pore is so as to dispelling the heat to this stator.
Progressive of the present utility model is that the pore on the wheel hub of motor can make the air of stator interior produce convection current, when motor running, can fully do the action of heat radiation to the stator of motor, simultaneously, the pore design can be reduced the pollution of dust in the inboard of groove.Aspect making, inside grooves design pore, the technology of available plastics ejection formation realizes therefore possessing practicality.In addition, such design is again unprecedented, so the novelty on the tool patent.
The utility model can be appointed by the those of ordinary skill in this professional domain and executed the craftsman and think and modify arbitrarily, but does not all break away from the scope of the desired protection of claim.
