Technical Field
The utility model relates to a wind power generation field, concretely relates to cooling system that aerogenerator used.
Background
The wind power industry is rapidly developed in recent years and is gradually upgraded and updated to further improve the heat exchange power, which is supported by social development requirements and national policies. In the past, the air-to-air or air-to-water coolers with 2MW-6MW power are generally adopted for cooling generators at home and abroad, and along with the updating of the wind energy industry, the power of the generators is continuously increased, and meanwhile, a cooling system also needs to be cooled in time according with the pace. At present, the cooling mode of the generator at home and abroad has two modes: air cooling and water cooling. Air cooling is the main cooling mode of wind power, but power promotion is difficult, and cooling efficiency is lower. The water-cooling power is high, the efficiency is high, the structure is complex, the space at the rear end cover of the generator is narrow, the positions of the air inlet and the air outlet are relatively dispersed, hot air pumped out from the air outlet of the generator needs to be transmitted to the heat exchanger through a long air pipe and then is sent into the air inlet of the generator after being cooled, and other parts on the rear end cover of the motor are easy to interfere when the air pipe is arranged, so that the maintenance is difficult.

In order to overcome the defect that powerful empty water cooling system installs and maintains the difficulty on the generator among the prior art, the utility model aims to provide a structural layout is reasonable, the 12MW half-direct drive permanent magnet wind power generator cooling system of the complexity of lowering system.
In order to achieve the above purpose, the utility model adopts the technical proposal that:
12MW directly drives permanent magnet wind power generator cooling system, including fan, tuber pipe and cooler, fan and cooler are installed in the generator, the fan has tuber pipe and cooler UNICOM, including two fans and a cooler, fan and cooler are installed in the terminal surface at the generator back, and two fan symmetries are installed in the both sides of cooler, and the intake stack is installed to the air intake of fan, the intake stack is installed in the air outlet of generator, and the air intake of cooler is connected through the tuber pipe to the air outlet of fan, the air-out pipeline is installed to the air outlet of cooler, the air intake of air-out pipe connection generator.
Furthermore, the top of the cooler is provided with air inlets respectively connected with the two fans, and the bottom of the cooler is provided with two air outlet pipelines.
Furthermore, the end surfaces of the air inlet pipeline and the air outlet pipeline connected with the generator are square flange surfaces and are positioned on the same plane.
Further, the fan is a centrifugal fan.
Further, the cooler is a water-cooling heat exchanger.
Furthermore, the two fans and the cooler are distributed in a triangular shape on the rear end face of the generator.
After taking above technical scheme, the beneficial effects of the utility model are that: the cooling system is arranged on a rear end cover of a motor of the wind driven generator, hot air in the generator set is pumped out through the left centrifugal fan and the right centrifugal fan, the hot air is conveyed through the air pipe and cooled through the cooler, and cooled cold air is finally sent into the generator set through an air outlet pipeline of the cooler to form a closed circulating system. The heat exchange is realized through the heat exchange between gas and water in the cooler, under the same heat exchange power, the refrigeration of the cooling system is twice that of a common cooler, and the cooling system structure is suitable for the use occasion of a generator and is convenient to install and maintain.

Detailed Description
The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings:
as shown in the figure, the cooling system of the 12MW semi-direct-drive permanent magnet wind driven generator is arranged on the back of a generator of an offshore wind power device to cool the generator. The air conditioner consists of a pair of centrifugal fans 1, a cooler 2 and a pair of air pipes 3 for connecting the fans 1 and the cooler 2. The end face of the back of the generator is provided with a pair of air outlets and a pair of air inlets, and the pair of air outlets and the pair of air inlets are distributed in a triangular mode on the end face of the back of the generator. An air inlet pipeline 4 is respectively installed at the air inlets of the centrifugal fans 1, the air inlet pipeline 4 is correspondingly communicated with the air outlet of the generator, and the air outlets of the centrifugal fans 1 are correspondingly communicated with the two air inlets at the top of the cooler 2 through the air pipes 3. Two air outlet pipelines 5 are arranged at the bottom of the cooler 2, and the two air outlet pipelines 5 are communicated with an air inlet of the generator to form a closed ventilation circulation. The end surfaces of the air inlet pipeline 4 and the air outlet pipeline 5 connected with the generator are square flange surfaces and are positioned on the same plane, so that the centrifugal fan 1 and the cooler 2 are conveniently installed on the back of the generator.
The cooler 2 is an air-water cooler, and a corrosion-resistant composite aluminum alloy fin brazing mode is adopted in the cooler to enhance the corrosion resistance of the system. The hot air sent by the fan is cooled by circulating seawater in the pipeline of the cooler, and the cooled cold air is sent into the generator. Four temperature sensors are arranged at the air inlet and the air outlet of the cooler 1, a G1/4' internal thread PT100 installation interface is reserved at the water outlet, the roughness is Ra3.2, and leads of other temperature sensors are connected into a junction box.
The cooler 2 is arranged on the rear end cover of the motor and is different from a traditional backpack type air-water structure, and the cooler 2 is opposite to the air inlet and the air outlet of the generator to form a closed circulating system. The hot gas that produces in the generator is taken out and is delivered to cooler 2 from the both sides air outlet of generator to centrifugal fan 1, and the recirculated cooling water in the cooler 2 is to the hot-air heat transfer, and inside the cold air after the heat transfer sent into the motor under centrifugal fan 1's effect, accomplished the heat transfer circulation, guaranteed that the operating temperature of generator is in reasonable within range. Because the double fans are matched with the single heat exchanger, the heat exchange air quantity is double that of the single fan, and the use requirement of a high-power generator is met.
