Abstract
The utility model discloses an air-cooled heat dissipating motor comprising a stand whose inner is provided with a stator and a rotor, wherein a lifting ring and a data plate are arranged on the upper portion of the stand, a foot is arranged on the lower portion, a blower fan is arranged on the rear end of a rotation shaft whose both ends extend outside the stand, an end cover is sleeved on the external end of the blower fan, the upper surface of radiating ribs arranged on the outer periphery of the stand is a slopping surface which is generally heightened from back to front, and the axial tangent plane of the radiating ribs is a right trapezoid. The radiating ribs are generally heightened from back to front, the heat dissipating convective area of the front ends of the radiating ribs is added, and the heat dissipating effect is greatly improved. A lengthening fan cover outside the radiating ribs effectively prevents the diffusion loss of cooled air along the radiation direction of the radiating ribs, which guarantees the wind power to flow along a channel of the radiating ribs, reduces the waste of the wind power and improves the heat dissipating effect, simultaneously, the diameter of an air inlet is reduced, the air leak of the air inlet is effectively prevented, the inner air pressure of the end cover is improved, a cutting device of the radiating ribs on the position of the date plate can prevent the date plate from blocking the air direction. The motor has the advantages of simple structure and obvious heat dissipating effect, and the motor effectively prevents the temperature rise of the front end of the motor.
Description
Technical field
The utility model belongs to motor heat dissipation technology field, particularly a kind of wind-cooling heat dissipating motor.
Background technology
At present, the cooling system of the enclosed motor that generally uses is made of radiating ribs, fan, fan housing.Fan housing covers fan, and the whirlwind that the fan rotation produces transfers to the radiating ribs that radial distributes, and distributes the heat that the motor operation produces by the convection current of whirlwind and radiating ribs.When whirlwind is exported in fan housing when running into radiating ribs, just disperse to the radiation direction of radiating ribs, make the radiating ribs front end be subjected to the convection current wind of minute quantity, radiating effect reduces greatly, and this just causes enclosed motor front end high temperature to be difficult for heat radiation.Simultaneously, the fan housing air inlet runs wind, and name plate of motor blocking-up radiating ribs all influences radiating effect.For reducing motor temperature, guarantee its continous-stable operation, generally take the way of " low load with strong power ", cause waste of electric energy.
The utility model content
The purpose of this utility model provides a kind of enclosed motor heat abstractor of good heat dissipation effect.
For achieving the above object, the technical solution of the utility model is: the wind-cooling heat dissipating motor, set the support of son and rotor in comprising, described upper part of the frame is provided with suspension ring, nameplate, the bottom is provided with footing, and the rotating shaft rear end that support is stretched out at two ends is provided with fan blade, fan blade outer end suit end shield, the radiating ribs upper surface of support periphery for from after increase gradually forward domatic, described radiating ribs axial slices is a right-angled trapezium.
The domatic gradient of described radiating ribs is 1: 50.
Described radiating ribs is provided with outward and the domatic long fan housing that is complementary.
Described long fan housing comprises watt and following watt, Shang watt be located on the radiating ribs of footing top, following watt is located at below the footing on the radiating ribs.
Described long fan housing is close to the radiating ribs setting.
Described long fan housing on watt is provided with the suspension ring breach.
The fixed position radiating ribs of described nameplate disconnects.
The utility model radiating ribs from after increase gradually forward, increased radiating ribs front end heat radiation to flow area, improved radiating effect greatly.The radiating ribs fan housing that extends outward effectively prevents cooling air along the divergence loss of radiating ribs radiation direction, guarantees that wind-force flows along the radiating ribs groove, reduces the wind-force waste, improves radiating effect; Simultaneously, dwindle the air inlet diameter, can effectively stop air inlet to run wind, improve blast in the end shield; Nameplate place radiating ribs disconnects and being provided with, and can avoid nameplate blocking-up wind direction.The utility model is simple in structure, and radiating effect is remarkable, has effectively avoided the temperature rise of motor front end.No longer " low load with strong power " uses suitable motor, reduces power consumption, energy savings.

Embodiment
Wind-cooling heat dissipating motor as shown in Figure 1, comprise support 1, set son and rotor in the described support 1, the upper outer circumference of support 1 is provided with suspension ring 2 and nameplate 3, the excircle bottom is provided with footing 4, all there is the external part of rotating shaft 5 at the two ends of support 1, and the rear end of rotating shaft 5 is provided with fan blade 6, fan blade 6 outer end suit end shields 7.Support 1 as shown in Figure 2, its excircle is provided with radiating ribs 8, the upper surface of radiating ribs 8 is that the gradient is 1: 50 domatic, and domatic 9 from after increase gradually forward, the axial slices of radiating ribs 8 is a right-angled trapezium.The radiating ribs 8 outer long fan housings 10 that are complementary with domatic 9 that are provided with, long fan housing 10 comprises watts 101 and following watt 102 two parts, Shang watt 101 most of areas that surround supports 1 top, be close to bolt on the radiating ribs 8 of footing 4 tops, following watt 102 in support 1 bottom, be close to bolt on the radiating ribs 8 of footing 4 belows, the rear end of long fan housing 10 along with the circumferential edge of end shield 7 along corresponding, and the tight unlikely race wind of contact matching.The fixing of long fan housing 10 also can be taked such method: long fan housing 10 Shang watt 101 and following watt 102 be close to radiating ribs 8 placements, at least two iron wires of usefulness or strip iron sheet hoop are in the periphery.In order to make long fan housing 10 can be close to radiating ribs 8 setting, long fan housing 10 on watt be provided with the breach 11 of suspension ring 2 on 101.For the flow direction of the set bolt blocking-up wind that do not make nameplate 3, disconnect radiating ribs 8 at the fixed position of nameplate 3, reserve the fixed position of nameplate 3, it directly is fixed on the surface of support 1.
In addition,, reduce wind loss, increase the blast in the end shield 7, the diameter of air inlet 12 is reduced 5%～10%,, improve radiating effect to prevent wind loss for the wind that prevents to enter end shield 7 screws out from the air inlet of larger caliber again.Owing to reduced wind loss, the diameter that can suitably reduce fan blade 6 to be reducing the inner heat of motor, and fan blade 6 diameter dimensions reduce 5%～10% for well.
Be not limited to above-mentioned execution mode,, also can reach the effect of good heat radiating if the overall dimension that requires motor hour, can make wind from the trench flow mistake between the radiating ribs 8 directly at the long fan housing 10 of the outside suit of motor.For the bigger environment of dust, can suitably increase the height of radiating ribs 8, long fan housing 10 is not set, so that the cleaning of the dust stratification of groove.For miniature motor, can not change the shape of radiating ribs 8, only the long fan housing 10 that will mate is is directly installed and used and is got final product.
