Description
Technical field
The utility model relates to motor field, especially a kind of cooling motor of double fan, the motor is usually used in fitness equipment
On material such as treadmill.
Background technique
Many families can buy treadmill and put exercise use at home, the ultra-thin treadmill of some volume compacts（Pacing exerciser）
Internal installation space is narrow, and the air circulation effect between external environment is poor, in addition motor power itself is low, when load generates heat
Fastly, thus cause treadmill inside installation space temperature rise fairly obvious, need to carry out good ventilation and heat to ensure motor energy
Long-term stable operation.The motor that this kind of treadmill uses is single fan coolling motor, and the both ends of the motor body are respectively equipped with
Aerofoil fan is arranged in the air inlet and air outlet being connected to inner cavity, air inlet one end, aerofoil fan rotation sucking air when work,
It dries to motor body, air flows in the ventilating duct between air inlet and air outlet, generation when taking away motor body work
Heat cool down motor body.But this cooling effect of motor that single fan is arranged in air inlet one end is not ideal enough,
Although aerofoil fan can continuously dry in air inlet one end to motor cavity, the cold wind being blown into is passing through narrow ventilating duct
The windage encountered in the process is big, and air velocity reduces when close to air outlet, and the heat taken away of divulging information easily accumulates in air outlet side,
In the case where air inlet side is continuously blown cold wind, the ventilation velocity of air outlet side is also very slow, to the cold of motor body
But heat dissipation effect is poor.
Utility model content
The technical problems to be solved in the utility model and the technical assignment of proposition overcome existing ultra-thin treadmill to use
Single fan motor is slow in air outlet side air velocity, and heat easily gathers, and causes the defect of air cooling effect difference, and the utility model mentions
For a kind of cooling motor of double fan, the cooling motor of the double fan is respectively provided with wind in the air inlet of motor body and air outlet both ends
Fan accelerates the air velocity in motor body in ventilating duct by two fan cooperations, enhances the wind-cooling heat dissipating to motor body,
Make the slow temperature rise of low-power machine.
The utility model solves the technical solution that technical problem uses：A kind of cooling motor of double fan, including it is equipped with ventilation
The motor body in road and motor shaft, the motor body both ends set up air inlet and air outlet, the air inlet and air outlet axis separately
To extending and being connected to ventilating duct, aerofoil fan is arranged on the motor shaft of air inlet side in motor body, it is characterized in that the electricity
Exhaust fan is arranged on the motor shaft of air outlet side in machine ontology.The utility model is using double fan cooling structure to used in small sky
Between, the low-power motor good heat radiating under internal-external air circulation poor condition, particular by the electricity in air outlet side
Exhaust fan is set on arbor, and the thermal current acceleration for gathering air outlet side is discharged from motor body, cooperates the axis of air inlet side
Flow fan collective effect accelerates the air velocity in ventilating duct, promotes the wind-cooling heat dissipating effect of motor.
As further improving and supplementing to above-mentioned technical proposal, the utility model uses following technical measures：It is described
Exhaust fan is centrifugal fan.Thermal current is sucked out along axial in centrifugal fan, and to after the thermal current radially pressurization along the circumferential direction
It throws away, the aerofoil fan of air inlet is cooperated to work together, faster air flowing cooling can be realized inside motor body；Edge
The running discharge with seam of thermal current cooperation motor installation position from the treadmill of circumferencial direction discharge, moreover it is possible to the installation space of motor
It carries out air-cooled, while the temperature rise of motor body and treadmill frame being allowed to be decreased obviously.
The flabellum radial dimension of the aerofoil fan is more than or equal to the outer diameter of motor body.The case where installation space allows
Under, the preferred flabellum radial dimension of the aerofoil fan outer diameter that is more than or equal to motor body, to motor body when aerofoil fan works
Blowing face can cover air inlet and motor body outer wall, flabellum is not only blown into cold front heavy rain motor sheet to air inlet when rotating
Internal portion, it is also same to dry motor body outer surface to cool down motor outer wall.In addition, the flabellum outer diameter of aerofoil fan is less than electricity
It also can be used in the case where machine ontology, small size aerofoil fan is not so good as large-size axis parts stream wind to motor body outer wall heat dissipation effect
It fans.
The air inlet and air outlet are circumferentially surround on the end face at motor body both ends to be correspondingly arranged, the ventilating duct
Wound motor axis is arranged and is connected to the air inlet and air outlet at both ends.It is corresponding around being arranged on the end face at motor body both ends
Air inlet and air outlet cooperate in motor body inner loop around the ventilating duct of arrangement, and circular cooling is realized to motor body inside
Comprehensive uniform wind-cooling heat dissipating is done to motor inside in air duct.
Motor body fast pulley on the motor shaft of air outlet side, the exhaust fan are set to air outlet and skin
On motor shaft between belt wheel.It drives treadmill belt continuously to move since the motor on treadmill is mostly used belt wheel output, output is passed
Dynamic belt pulley is fixed on the motor shaft of air outlet side, makes exhaust fan between air outlet and belt pulley, such cloth
Office facilitates the cooling heat dissipation of motor body, and it is empty that belt pulley not will not influence aerofoil fan sucking on the motor shaft of air inlet side
Gas is dried to motor body, while the thermal current that centrifugal fan is taken out of can be along the circumferential direction between slave pulley and air outlet
It is smoothly discharged in gap.
The utility model by double fan cooling structure it is poor to small space, internal-external air circulation etc. under the conditions of use
Low-power motor good heat radiating, exhaust fan is set particular by the motor shaft of air outlet side, makes air outlet side
The thermal current acceleration of accumulation is discharged from motor body, cooperates the aerofoil fan collective effect of air inlet side, accelerates in ventilating duct
Air velocity promotes the wind-cooling heat dissipating effect of motor.
