Abstract
The utility model provides a kind of air guide structure reducing the loss of motor axial fan cooling air, the load side left and right sides is provided with two load side wind scoopers, one end of these two load side wind scoopers is all fixed on the edge of motor, the other end is all towards load side, and aerofoil fan rear portion is fixed with aerofoil fan collection solar or lunar halo; The cooling air solving aerofoil fan generation runs off in a large number and cannot blow to the problem of load side end cap with load side cooling air, improve motor cooling air utilance, promote cooling-down effect comparatively remarkable, extend motor useful life, save maintenance of motor expense, guarantee continous-stable is kept the safety in production, and reduces production cost.
Description
Technical field
The utility model belongs to reduction motor running temperature field, relates to a kind of air guide structure reducing the loss of motor axial fan cooling air.
Background technology
The unload side of motor is equipped with the aerofoil fan into electric motor temperature reduction, and the cooling air that aerofoil fan produces is blown into the radiating ribs on motor housing by the gap of fan guard and motor unload side end cap, reach the object of reduction motor temperature.The wind sucked due to part aerofoil fan is shed by fan guard surrounding on motor unload side end cap, and the cooling air causing aerofoil fan to produce runs off in a large number, causes whole motor radiating effect to reduce; Cannot blow to motor load end end cap when cooling air flow to motor load end by radiating ribs in addition, cause motor fore bearing to dispel the heat comparatively slow, thus increase the maintenance cost of motor, what affect motor benefits from the life-span.
Summary of the invention
The purpose of this utility model is to provide a kind of air guide structure reducing the loss of motor axial fan cooling air, and the cooling air produced to solve aerofoil fan runs off in a large number and cannot blow to the problem of load side end cap with load side cooling air.
The utility model reduces the air guide structure of motor axial fan cooling air loss, the load side left and right sides is provided with two load side wind scoopers, one end of these two load side wind scoopers is all fixed on the edge of motor, the other end is all towards load side, and aerofoil fan rear portion is fixed with aerofoil fan collection solar or lunar halo; Improve motor cooling air utilance, promote cooling-down effect comparatively remarkable, extend motor useful life, save maintenance of motor expense, ensure continous-stable safety in production, reduce production cost.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
As shown in Figure 1, the air guide structure of the utility model minimizing motor axial fan cooling air loss comprises load side 1 left and right sides and is provided with load side wind scooper 1 and load side wind scooper 29, one end of load side wind scooper 1 and one end of load side wind scooper 29 are all fixed on the edge of motor 3, the other end of load side wind scooper 1 and the other end of load side wind scooper 29 are all towards load side 1, and aerofoil fan 5 rear portion is fixed with aerofoil fan collection solar or lunar halo 7.
After using the utility model to reduce the air guide structure of motor axial fan cooling air loss, motor winding temperature on average reduces by 6.8 DEG C, and motor load end bearing temperature reduces by 1.6 DEG C, and unload side bearing temperature reduces by 2.4 DEG C, promotes cooling-down effect comparatively remarkable.
