Description
Technical field
The present invention relates to a kind of electromechanics structure, especially a kind of air compressing structure being applicable to clockwise and anticlockwise outer space cool electric machine.
Background technique
For general existing middle and small motor (as Y-series threephase asynchronous machine), the type of cooling is outer air cooling, and cooling structure comprises casing radiating fin, the fan be arranged on machine shaft, fan housing.Electric machine rotation provides power for fan, and outside air, through fan housing and fan, brushes casing radiating fin vertically, takes away motor heat by forced-convection heat transfer.
For obtaining good radiating effect, when not changing casing radiation fin structure, the exhaust outlet of fan housing must provide higher blast and larger air mass flow.For constant-seed motor, the internal structure of fan and fan housing determines the air-flow character of fan cover air outlet.
Fan and the fan housing structure of a large amount of employing are at present fairly simple, and fan housing inside there is no the structure of air flowing of adjusting.On the one hand, when centrifugal fan rotates, inner air turbulent flow content, noise and frictional loss are all comparatively large, centrifugal fan efficiency and fan cover air outlet blast lower, the fin structure radiating effect on motor case is deteriorated.On the other hand, centrifugal fan rotates and fan cover air outlet air is not flowed vertically, angle is there is between the direction of speed air flow and casing radiating fin, fan cover air outlet air is caused to start to lose part kinetic energy when entering casing radiating fin gap just, cause waste, reduce fin structure radiating effect.Therefore, improve original fan and fan housing structure, human intervention fan housing inner air mobility status, air-flow direction of adjusting, significant to improving motor radiating effect and improving electric efficiency.
Summary of the invention
The object of the invention is to propose a kind of air compressing structure being applicable to clockwise and anticlockwise outer space cool electric machine, adjust fan housing into and out of air port air-flow direction, reduce fan housing inner air turbulent flow content, noise and frictional loss, improve centrifugal fan efficiency and fan cover air outlet blast, strengthen motor fin structure heat dissipation potential, reduce electromechanics loss, improve electric efficiency.
For achieving the above object, technological scheme of the present invention is: a kind of air compressing structure being applicable to clockwise and anticlockwise outer space cool electric machine, comprise fan housing, centrifugal fan, fan housing ear end face is provided with the orifice plate of intake grill, centrifugal fan is arranged on machine shaft, straight intake grill straightener(stator) blade is enclosed in the orifice plate inner surface radial direction welding one of described intake grill, and intake grill straightener(stator) blade is along the circumferential direction uniform, the exhaust outlet straightener(stator) blade that near the exhaust outlet of described fan housing, inner surface radial direction welding one circle is straight, and exhaust outlet straightener(stator) blade is along the circumferential direction uniform, and align one by one with described intake grill straightener(stator) blade, the air that makes to adjust is vertical with centrifugal fan sense of rotation all the time through out-of-date velocity attitude with exhaust outlet from fan housing intake grill, the intake grill parallel with centrifugal fan blades and exhaust outlet air, disperse along the expansion of centrifugal fan blades gap uniformity.
The quantity of intake grill straightener(stator) blade and exhaust outlet straightener(stator) blade is 2 times of centrifugal fan blades quantity.
Fan housing is arranged on the casing radiating fin of motor, and the exhaust outlet of fan housing is to the casing radiating fin of alignment motor.
Leave gap between intake grill straightener(stator) blade and the blade of centrifugal fan, the width of intake grill straightener(stator) blade is the width of blade of 0.3 times of centrifugal fan.
Leave gap between exhaust outlet straightener(stator) blade and centrifugal fan blades, the width of exhaust outlet straightener(stator) blade is the width of blade of 0.25 times of centrifugal fan.
The invention has the beneficial effects as follows:
The present invention is on general motor centrifugal fan and fan housing structure basis, and fan housing inside adds a series ofly flows blade with static expansion of centrifugal fan structure matching, as intake grill straightener(stator) blade and the exhaust outlet straightener(stator) blade of centrifugal fan.Centrifugal fan, fan housing, static expansion stream blade form air compressing structure together with electric motor end cap, for the radiating structures such as casing radiating fin provide higher blast and larger air mass flow, strengthen cross-ventilation heat exchange, and air-flow direction of adjusting, axial flow is provided.The present invention a series ofly flows blade with static expansion of centrifugal fan structure matching by adding in fan housing inside, and air of adjusting is vertical with centrifugal fan sense of rotation all the time through out-of-date velocity attitude with exhaust outlet from intake grill.On the one hand, when centrifugal fan rotates, vertical with sense of rotation, parallel with centrifugal fan blades intake grill and exhaust outlet air, disperse along the expansion of centrifugal fan blades gap uniformity.Therefore inner air turbulent flow content, noise and frictional loss be can reduce, centrifugal fan efficiency and fan cover air outlet blast improved.On the other hand, through the air of fan cover air outlet straightener(stator) blade, its velocity attitude and motor parallel to an axis, and between the axial fin on support, angle is almost nil.Fan cover air outlet air can being avoided to lose part kinetic energy when just starting to enter fin clearance, avoiding the heat dissipation potential of wasting casing radiation fin structure.
