Abstract
The utility model relates to a aerogenerator sliding ring room cooling structure, this structure include one install air cooler (3) in aerogenerator (10) top, be air intake (1) at air cooler (3) front end, have the slip ring room (6) upper portion at air cooler (3) rear end air outlet (4) below processing at opening and aerogenerator (10) rear portion to communicate with each other, process gas vent (8) in slip ring room (6) lower part. Air enters the air cooler (3) body under the action of the air cooler fan (2), is subjected to heat exchange with the wind driven generator (10) and then is discharged through the air outlet (4) of the air cooler, and meanwhile, a part of air enters the slip ring chamber (6) downwards through the opening, cools a slip ring (7) and a bearing (9) in the slip ring chamber (6) and then is discharged through the air outlet (8) below.
Description
Technical Field
The utility model relates to a aerogenerator slip ring room cooling structure belongs to the cooling technical field of motor.
Background
In recent decades, wind power generation technology has been developed dramatically. China becomes the first wind-powered country worldwide. The generator is used as a core component in the wind power industry, the product quality restricts the development of the wind power industry, and particularly, higher requirements are put forward on the temperature rise of the generator.
Disclosure of Invention
The utility model discloses just to the problem that exists in the above-mentioned current trade demand and the technique and a aerogenerator slip ring room cooling structure who designs, its purpose is the indoor sliding ring of solution sliding ring and the refrigerated problem of bearing.
The purpose of the utility model is realized through the following technical scheme:
this kind of aerogenerator sliding ring room cooling structure, its characterized in that: the structure comprises an air cooler 3 arranged above a wind driven generator 10, wherein an air inlet 1 is arranged at the front end of the air cooler 3, an opening is processed below an air outlet 4 at the rear end of the air cooler 3 and communicated with the upper part of a slip ring chamber 6 at the rear part of the wind driven generator 10, and an exhaust port 8 is processed at the lower part of the slip ring chamber 6.
Furthermore, an exhaust pipe 5 is sleeved on an opening processed below an air outlet 4 at the rear end of the air cooler 3 and is directly butted at the air outlet position of the air cooler 3.
Further, the slip ring chamber 6 comprises an inner slip ring 7 and a bearing 9.
Further, an air cooler fan 2 is installed at an air inlet 1 at the front end of the air cooler 3.
Furthermore, the air quantity passing through the exhaust pipe 5 is 40-60% of the air quantity of the air outlet 4 at the rear end of the air cooler 3.
Further, the cooling structure is made of steel or aluminum alloy.
Air enters the air cooler 3 body under the action of the air cooler fan 2, is subjected to heat exchange with the wind driven generator 10 and then is discharged through the air outlet 4 of the air cooler, meanwhile, a part of air downwards enters the slip ring chamber 6 through the opening, cools a slip ring 7 and a bearing 9 in the slip ring chamber 6 and then is discharged through the lower air outlet 8.
Drawings
FIG. 1 is a schematic view of the structure of the present invention
Detailed Description
The structure of the present invention will be further described in detail with reference to the accompanying drawings and examples:
referring to the attached drawing 1, in the slip ring chamber cooling structure of the wind driven generator, an air cooler fan 2 is embedded in an air cooler air inlet 1 and connected with an air cooler body 3 and an air cooler air outlet 4 to form an air cooler main body, and the air cooler main body is connected with a slip ring chamber 6 and a generator 10 to complete a wind driven generator system. Air enters the air cooler body 3 under the action of the air cooler fan 2, is subjected to heat exchange with the generator 10 and then is discharged through the air cooler air outlet 4 and the slip ring chamber air outlet 8, and partial air discharged by the air cooler is used for cooling the slip ring 8 and the bearing 9 in the slip ring chamber through the slip ring chamber 6.
