Description
Technical field
The utility model relates to electrical generator fields, relates in particular to a kind of Novel stator ventilation ducts structure.
Background technology
Along with the progress of design of electrical motor and manufacturing technology, the capacity of motor improves constantly, and power density constantly increases, and it is more and more serious that its loss, heating and ventilating problem also become.In order to ensure reliability service and the useful life of large-size machine, be necessary to improve ventilation effect and reduce the wastage.
The loss of motor generally comprises rotor copper loss (resistance loss), core loss, bearing loss, draft loss and other losses, and wherein draft loss is occupied very large proportion in motor total losses.Motor is in running, stator winding produces copper loss and generates heat, stator core, because iron loss is generated heat, is mainly taken away the heat of stator winding and stator core generation by the refrigerating gas of the stator ventilation ducts of flowing through, thereby is ensured that stator temperature rise is in prescribed limit.Stator ventilation ducts supports (ventilation ducts of the prior art is supported for ventilation ducts and supports) by vent segment and multiple ventilation ducts and forms, stator ventilation ducts comprises multiple ventilation ducts structures, the passage that each ventilation ducts structure is supported by two ventilation ductss and upper and lower vent segment surrounds forms, and heat exchange occurs on the surface that the refrigerating gas of the stator ventilation ducts of flowing through and vent segment and ventilation ducts support.But in the prior art, the cooling effect of stator depends primarily on the effect of the refrigerating gas of the stator ventilation ducts of flowing through and the surface generation heat exchange of vent segment and ventilation ducts support, wherein, the heat exchange area of refrigerating gas flow, flow velocity and fluidised form, vent segment etc. is all the principal elements that affect stator heat radiation.And existing stator ventilation ducts structure is limited by area of dissipation and refrigerating gas fluidised form, the cooling effect of refrigerating gas is still poor, and stator temperature rise also just can not get effectively reducing.
Utility model content
The purpose of this utility model is to overcome the above-mentioned problems in the prior art, and a kind of Novel stator ventilation ducts structure is provided, and the utility model can improve refrigerating gas mobile turbulence level in ventilation ducts, reaches the object that improves stator cooling effect.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of Novel stator ventilation ducts structure, it is characterized in that: comprise that ventilation ducts supports, described ventilation ducts is fixedly installed multiple surface-supported spoilers of ventilation ducts that protrude from supporting, and described spoiler stretches into by this ventilation ducts and supports in the ventilation ducts forming with upper and lower vent segment.
Described spoiler is inclined in ventilation ducts along the refrigerating gas direction that flows, and the incline direction of adjacent two spoilers that same ventilation ducts supports is contrary.
Distance between the front end of described spoiler and lower vent segment is less than the distance between rear end and lower vent segment, and the distance between the front end of adjacent spoiler and lower vent segment is greater than the distance between rear end and lower vent segment.
The quantity that described ventilation ducts supports is two, and the spoiler that described two ventilation ductss support is symmetrical.
Employing the utility model has the advantage of:
One, the utility model is provided with multiple surface-supported spoilers of ventilation ducts that protrude from ventilation ducts supports, can either make refrigerating gas in ventilation ducts, form disorderly air-flow by spoiler, can improve again the flowing velocity of refrigerating gas in ventilation ducts, be conducive to improve the heat exchanger effectiveness of refrigerating gas and vent segment, reach the object of quick cooling stator.
Two, in the utility model, described spoiler is inclined in ventilation ducts support along the mobile direction of refrigerating gas, and on same ventilation ducts supports, distance between the front end of described spoiler and lower vent segment is less than the distance between rear end and lower vent segment, distance between the front end of adjacent spoiler and lower vent segment is greater than the distance between rear end and lower vent segment, this structure makes every spoiler to play flow-disturbing effect to refrigerating gas, is conducive to rapidly refrigerating gas be upset into disorderly turbulent flow fluidised form.
Three, in the utility model, the quantity that described ventilation ducts supports is two, and the spoiler that described two ventilation ductss support is symmetrical, and this structure can alternately upset air-flow repeatedly, is conducive to accelerate the radiating rate of stator.

Fig. 2 is the A-A partial sectional view in Fig. 1.
Fig. 3 is the structural representation that in the utility model reality, ventilation ducts supports.
Being labeled as in figure: 1, ventilation ducts supports, 2, upper vent segment, 3, lower vent segment, 4, spoiler, 41, rear end, 42, front end.
Embodiment
A kind of Novel stator ventilation ducts structure, comprise that two ventilation ductss support 1, described two ventilation ductss support and on 1, are provided with multiple spoilers 4 that protrude from ventilation ducts and support 1 surface, and the spoiler 4 in two ventilation ducts supports 1 is symmetrical, so that repeatedly alternately upset air-flow, make refrigerating gas in ventilation ducts, form very disorderly turbulent flow, described spoiler 4 stretches in the ventilation ducts being formed by these two ventilation ductss supports 1 and upper vent segment 2 and lower vent segment 3, described spoiler 4 is inclined in ventilation ducts along the mobile direction of refrigerating gas, and the incline direction that same ventilation ducts supports adjacent two spoilers 4 on 1 is contrary, distance between the front end 42 of described spoiler 4 and lower vent segment 3 is less than the distance between rear end 41 and lower vent segment 3, distance between front end 42 and the lower vent segment 3 of other spoiler 4 adjacent with this spoiler 4 is greater than the distance between rear end 41 and lower vent segment 3, the every spoiler 4 that so just makes ventilation ducts support on 1 can both play flow-disturbing effect to refrigerating gas, the heat exchange of refrigerating gas and vent segment is just very abundant, also just better to the cooling effect of stator.
In the utility model, it is channel-section steel that described ventilation ducts supports 1, the preferred integral type of described spoiler 4 is arranged on channel-section steel, make the processing of spoiler 4 convenient, but be not limited to above-mentioned preferred implementation, it can also be the square channel-section steel of hollow that for example described ventilation ducts supports 1, and described spoiler 4 also can be welded on separately ventilation ducts and support on 1.
