Abstract
The utility model relates to a large-scale aerogenerator air-air type cooler which relates to the electrical, machinery, thermotechnical and fluid fields. A heat exchange mode adopted by the cooler is an air-air type heat exchange mode. That is to say, a heating circuit (a primary wind path) and a cooling circuit (a secondary wind path) both adopt an air heat exchange mode. The structure of the cooler is as follows: the cooler comprises a radial centrifugation blower fan, a housing assembly, two axial centrifugation blower fans and a conjunction box (4). By the adoption of a primary wind path and secondary wind path combined cooling mode, the large-scale aerogenerator air-air type cooler has a compact structure and occupies a small space. And as the axial centrifugation blower fans and the radial centrifugation blower fan are installed outside the housing assembly and are connected by the use of bolts, the large-scale aerogenerator air-air type cooler can be integrally detached and installed and is convenient to maintain. Windage and friction loss of the generator can be controlled at a low level and it can be guaranteed that temperature rise of the generator meets requirements. Power consumption is low as well as the windage and friction loss. The cooler has advantages of integrated circuit and convenient operation. All cable conductors are integrally connected in the conjunction box and are convenient to operate and maintain.

Technical field
The utility model relates to a kind of large-scale wind driven generator with air-air formula cooler, relates to electric, mechanical, thermal technology and fluid field.
Background technology
Early stage wind-driven generator is because power is less, and its caloric value is also little, only needs just can reach the cooling requirement by natural draft effectively.Yet along with the power of wind-driven generator progressively increases, natural draft can't have been satisfied the cooling requirement of unit, and existing MW class wind turbine cooler, complex structure, take up room big, be not easy to safeguard.At present, many coolers adopt sky-water cooling modes, though volume is little, efficient is high, and the cost height, security risk height, maintenance difficulties are big.In order to strengthen cooling effect, the air quantity of fan is big in theory, wind speed is high beneficial to the temperature rise of further reduction generator, but this can cause cooling fan oversize, and then has increased the abrasion of generator wind, and generator efficiency is reduced.Therefore, can be controlled at reduced levels and can guarantee under the satisfactory prerequisite of temperature rise in the wind abrasion of generator, produce that cost is low, heat exchange efficiency is high, compact conformation, big capacity wind-driven generator cooler easy to maintenance will be one of our difficult problem of facing.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and the large-scale wind driven generator that provide that a kind of air quantity is big, wind speed is high, the wind abrasion is little, simple and compact for structure, heat exchange efficiency is high, maintain easily, thermal capacity is big is with air-air formula cooler.
For reaching the technical scheme that the purpose of this utility model adopts be: a kind of large-scale wind driven generator is with air-air formula cooler, it is characterized in that described this large-scale wind driven generator is air-air formula heat exchange structure with the heat exchange mode that air-air formula cooler adopts, it comprises a radially centrifugal blower that sucks the external environment condition cooling air, housing assembly, two axial-centrifugal fans that absorb the generator distribute heat and terminal box;
Two axial-centrifugal fans of described absorption generator distribute heat are arranged on housing assembly right-hand member two bottom sides, these two axial-centrifugal fans through the pipeline of housing assembly inside to housing assembly left end bottom go out the interruption-forming heating circuit, promptly be called wind path one time;
The radially centrifugal blower of described suction external environment condition cooling air is arranged on the housing assembly left-hand end, this radially the pipeline of centrifugal blower through housing assembly inside to housing assembly, form cooling circuit, promptly be called the secondary wind path.
Described terminal box is arranged on the housing assembly, all cables is concentrated be connected in the terminal box.
The heat exchange mode that this cooler adopts is air-air formula heat exchange, and promptly a wind path (heating circuit) and secondary wind path (behind the cooling circuit) all adopt the air heat exchange.Wherein, a wind path comprises housing assembly and two axial-centrifugal fans; The secondary wind path comprises radially centrifugal blower and the housing assembly that is positioned at the housing assembly left part.
Wind path: two axial-centrifugal fans that are installed in housing assembly right-hand member two bottom sides, the hot-air that will absorb generator (cooler target) distribute heat sucks housing assembly inside, after the tube-cooled of hot-air through housing assembly inside, discharge from the outlet of housing assembly left end bottom again, inflow generator inside forms the circulation of sealing.
Secondary wind path: the radially centrifugal blower that is installed in the housing assembly left-hand end, suck the cooling air in the external environment condition, again cooling air is blowed to the pipeline of housing assembly inside, take away the required heat that distributes when cooling air is flowed through pipeline, discharge outdoor at last.
The utility model is owing to adopted wind path and the type of cooling that the secondary wind path combines, and this cooler has following characteristics: one, compact conformation, take up room little; Two, axial-centrifugal fan and radially centrifugal blower be installed in housing assembly outside, and adopt bolt to connect, but integral demounting and installation are easy to maintenance; Three, the wind abrasion of generator can be controlled at reduced levels and can guarantee that its temperature rise meets the requirements, and power consumption is little and the wind abrasion is little; Four, circuit is integrated, easy to operate, all cables is concentrated be connected in the terminal box handled easily and maintenance.
