The utility model relates to an electric generator with a water sleeve cooling mechanism. The electric generator comprises a stator, a rotor and a main shaft. The rotor is arranged inside the stator. The main shaft penetrates through the rotor and is connected with the rotor. A cable is arranged between the rotor and the stator. The electric generator is characterized by further comprising a water sleeve machine seat used for cooling. The water sleeve machine seat has an annular structure and is sleeved outside the stator. The water sleeve machine seat comprises a water inlet, a water outlet and a circulation water channel. The water inlet and the water outlet are connected with the circulation water channel. The beneficial effects of the electric generator with the water sleeve cooling mechanism are that heat of the rotor and a coil short part can be effectively brought out to be cooled by an internal circulation wind path in a circulation way through an internal wind pipe of the water sleeve. Practical verification indicates that integral temperature rising is lowered, and thus efficiency of a motor and reliability of use are enhanced.
Description
Technical field
The utility model relates to a kind of wind-driven generator, particularly relates to a kind of generator with the water jacket cooling body.
Background technology
In the wind-driven generator running, because the loss of electric machine makes heat, constantly accumulate, cause the temperature of motor internal to rise gradually.If not rationally, circulating cooling wind path structure fast and effectively, motor internal temperature rising fast can cause the reduction of insulation life, motor burning even occurs, reduces the reliability of product.The support of motor often also can be exaggerated because temperature rise can't meet specification requirement simultaneously, thereby causes the volume of motor, weight to increase, and cost raises, and competitiveness is lost.
Wind-driven generator is due to the particularity of running environment, except the reliability of motor operation, compact and light-dutyly turn to the focus that the client pays close attention to, so water-jacket typ cooling structure type has been subject to the favor in market.The two-layer equation water jacket that existing water jacket structure often adopts water channel and wind path to separate, radial ventilation groove and axial ventilation hole are not established in inside simultaneously, cause water jacket and inner heat exchange area to reduce, inner wind path circulation is smooth, leak out and can't in time heat be taken out of so that temperature rise too high.

The utility model is exactly in order to address the above problem, and overcomes the existing problem of wind-driven generator in prior art, and the utility model provides a kind of generator with the water jacket cooling body to satisfy the demands.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of generator with the water jacket cooling body, comprise stator, rotor and main shaft, described rotor is arranged in stator, main shaft is connected with rotor through rotor, and cable is arranged between rotor and stator, it is characterized in that, also comprise the water jacket support for cooling, described water jacket support is loop configuration and is set in outside stator, on described water jacket support, comprises water inlet, delivery port and cyclic water channel, and water inlet, delivery port connect cyclic water channel.
Above-mentioned a kind of generator with the water jacket cooling body, it is characterized in that, described cyclic water channel is the cirque structure of sealing, the first partition panel that equals the cirque structure width by a length in cyclic water channel separates cirque structure, the second partition panel that remaining part is shorter than the cirque structure width by plural block length in cyclic water channel is crisscross arranged and will cuts off into cyclic water channel in cirque structure, and described water inlet and delivery port are connected respectively the water channel of the both sides of the first partition panel.
Above-mentioned a kind of generator with the water jacket cooling body, it is characterized in that, described stator forms by the long-pending sheet of plural pieces stator lamination, be provided with stator radial ventilation groove between stator lamination and stator lamination, described rotor forms by the long-pending sheet of plural pieces rotor lamination, is provided with the rotor radial ventilation slot between rotor lamination and rotor lamination.
Above-mentioned a kind of generator with the water jacket cooling body, is characterized in that, is provided with axial stator shaft orientation ventilation hole on described stator, is provided with axial rotor axial ventilation hole on described rotor.
The beneficial effects of the utility model are: by the jacket structure for water that adopts water channel and wind path to merge, be provided with radial ventilation groove and axial ventilation hole during stator same, the unsupported side end panel of stator is not established axial ventilation hole, and unsupported side end panel is established axial ventilation hole, is provided with rational interior wing and wind deflector simultaneously.This kind of structure both guaranteed that the stator heat was by shedding with the conduction of water jacket heat, also prevented interior wind path air leakage phenomena simultaneously, interior circulation wind path can effectively be taken out of by airduct in water jacket cooling by the circulation of the heat of rotor and the short section of coil, actual verification shows to have reduced whole temperature rise, the reliability of lifting motor efficiency and use.
