Abstract
Disclosed is a radiator for an air-cooled generator. One end of an air scooper of the radiator is open and the other end is provided with an air intake hole at the center; the air scooper is installed outside a generator shell and an air guide channel is formed between the generator shell and the air scooper; and a fan is installed on a generator shaft and is disposed in the room between the front end of the generator and the air scooper. The fan of the radiator rotates along with the generator shaft to generate air pressure to enable the air intake hole of the air scooper to suck cold air which is then blown to a rear end cap to cool a rectifier bridge and a voltage adjustor and then flows through the outer surface of the shell and finally flows to the outside from the outer surface of the shell close to a front end cap. The radiator has the advantages of high efficiency of the fan cooling mode and tight sealing of the natural cooling mode. The air flows to the outside from the surface of the shell without flowing through the surfaces of the stator and the rotor of the generator, so no static interference can be appeared on the generator and the generator can not generate static. Therefore, the generator can be safer and more reliable in operation, the service life of the generator is greatly improved and the maintenance time is largely reduced.
Description
Technical field
The utility model relates to a kind of heat abstractor of wind cooling DC generator.
Background technology
Adopt the radiator fan of the generator of air-cooled forced ventilation heat radiation to be designed to interior air channel form more, the design in air channel makes the air-flow of generator outside directly to walk heat by stator, the rotor banding of generator in this, but in actual working environment, the internal temperature of generator is higher, fan high-temperature gas easily ionizable in the running produces static, and on generator, accumulate, both may cause the infringement of electronic devices and components in the generator also may jeopardize the safety that touches the generator personnel accidentally.Because the air inlet of most generator does not have filter, under the environment of many dirt, a large amount of dusts of its inner easily accumulation reduce useful life to generator for a long time in addition.
Summary of the invention
Goal of the invention of the present utility model is to provide the reliability that do not produce electrostatic interference, good cooling results, generator on a kind of generator and safe air-cooled generator heat abstractor.
The technical solution of the utility model is: a kind of air-cooled generator heat abstractor, and its wind scooper one end is a unenclosed construction, there is fresh air inlet at its other end center; It is external that wind scooper is loaded on generator body, forms an air-guiding aisle between generator housing and wind scooper; Fan is loaded on generator shaft and places between generator front end shell and wind scooper.
Generator body external surface of the present utility model has radiating ribs.
Fan part of the present utility model produces blast with the generator shaft rotation, fresh air inlet inspiration cold air from wind scooper blows to the rear end cap parts then, cooling rectifier bridge, voltage regulator, the housing outer surface of flowing through again flows to atmosphere from the housing outer surface near front end housing at last.
The utility model ventilated machine radiating mode combines the advantage of fan cooled and natural cooling, has the sealing of fan-cooled high efficiency and natural cooling simultaneously.Owing to do not have air flow stream to cross stator, rotor surface, but flow in the atmosphere through surface of shell, do not produce electrostatic interference on the generator, generator just can not produce static, and in service safer, reliable, increase useful life greatly, and maintenance frequency reduces.The radiating ribs of the airflow passes housing outer surface that fan rotation simultaneously produces has increased the effect of cooling off, and the reliability of generator and fail safe improve greatly like this.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the utility model structural representation.
Embodiment
In the accompanying drawing, stator 6, rotor 7, excitation component 8 are arranged in the generator housing 5, there is generator shaft 9 at its center, and generator shaft 9 is connected with generator housing 5 through bearing 1.Generator housing 5 front and back have front end housing 4 respectively
-1, rear end cap 4
-2 Wind scooper 2 one ends are unenclosed construction, and there is fresh air inlet at its other end center; Wind scooper 1 is loaded on outside the generator front end shell 5, forms an air-guiding aisle at generator housing 5 and 2 of wind scoopers; Fan 3 is loaded on generator shaft 9 and places the generator front end shell and 2 of wind scoopers.Generator housing 1 outer surface has radiating ribs.
Claims (2)
1, a kind of air-cooled generator heat abstractor, it is characterized in that: wind scooper one end is a unenclosed construction, there is fresh air inlet at its other end center; It is external that wind scooper is loaded on generator body, forms an air-guiding aisle between generator housing and wind scooper; Fan is loaded on generator shaft and places between generator front end shell and wind scooper.
