Fig. 1 is active second wind cooling System Working Principle figure at the bottom of this utility model wind-power electricity generation closed tower；
Fig. 2 is active second wind cooling system layout figure at the bottom of this utility model wind-power electricity generation closed tower.
Detailed description of the invention
At the bottom of wind power generating set closed tower actively second wind cooling system by once circulating wind path in tower and secondary fresh air outer circulation wind path is constituted, one time wind path carries out coupled and heat-exchange with secondary wind path by plate type heat exchanger in tower, power consumption components at the bottom of tower is dispelled the heat, simultaneously the regulation to tower base ring environmental temperature and humidity.
It is illustrated in figure 1 SAPMAC method schematic diagram in active second wind cooling system at the bottom of tower, including circulating fan 3,7,8, the plate type heat exchanger 6 being positioned on tower two-layer platform 12, is installed on the heater 14 within a wind path backwind tube 5.First air trackside, converter 1 air-out enters inside wind collection 2 under fan 3 drives, under fan 3 and 8 coupling in plate type heat exchanger 6 primary side air inlet/outlet pipeline, one time wind path flows through plate type heat exchanger 6 inside, First air flows back to environment in tower, approach primary retirn air pipeline 5 internal heater 14 by a wind path backwind tube 5.Secondary side wind path, under fan 7 on plate type heat exchanger 6 secondary side wind pipe 9 drives, outside tower, new wind enters secondary side intake stack 10, flow through the internal secondary air channel passage of plate type heat exchanger 6, flow out outside tower eventually through secondary side wind pipe 9, one time wind path carries out coupled and heat-exchange with secondary wind path air by plate type heat exchanger 6, will once be taken in the outer atmospheric environment of tower by the interior wind path atmospheric heat that circulates by the new wind of secondary wind path.Air themperature and humidity in a temperature-humidity sensor monitoring tower it is respectively arranged with at the bottom of tower.
It is illustrated in figure 2 active second wind cooling system layout figure at the bottom of wind power generating set closed tower.Using totally enclosed type design at the bottom of tower, tower wall 11 will separate with external environment at the bottom of whole tower completely with tower two-layer platform 12, forms totally enclosed type tower base ring border.At the bottom of tower, converter 1 judges device temperature controlled fan 3 by its internal temperature sensor, 7, the start and stop of 8, at fan 3, after driving low-converter 1 air-out of 8 flows through plate type heat exchanger 6 heat radiation, cold wind comes back in tower base ring border, finally sucked converter 1 inside by converter 1 bottom air inlet mouth 4 negative pressure to absorb heat, complete a wind path circulation in tower.Plate type heat exchanger 6 and secondary air path pipeline 9,10 are positioned on tower two-layer platform, and under the driving of fan 7, outside tower, a wind path heat is dispersed in atmospheric environment after being completed heat exchange by secondary wind path intake stack porch negative pressure suction plate type heat exchanger 6 inner passage with a wind path by new wind.Whole tower base ring border fully seals, and the outer high humidity of tower, high corrosion air can be stoped to enter in tower, significantly reduces corrosion and the condensation risk of equipment in tower.In wind collection 2, there is a temperature sensor, measure the leaving air temp of power consuming devices.
Air-cooled loop control mainly includes herein below:
1) when converter 1 exceeds setting value as the internal temperature of power consuming devices, start fan 3 simultaneously, 7,8, carry out cold fluid and hot fluid heat exchange by plate type heat exchanger 6, circulation wind path air themperature in reducing once；
2) when in tower air themperature less than in time setting, open fan 3,8, close fan 7, heater 14, carry out circulation in tower, circulation wind path air themperature in promoting once, to improve ambient temperature in tower；
3) when in tower relative air humidity higher than when setting, open fan 3,8, heater 14 promotes circulation wind path air themperature in once, heats air in tower, to reduce the relative humidity of air in tower, reduces condensation risk.
Conventional converter 1 generally dispels the heat for lower ending opening on one side, opposite another side opens multiple louvre convection current, powerful configuration fan and leaving air temp sensor carry out adding high wind heat loss through convection, but the converter 1 own local environment low at tower is more severe, large number quipments is arranged at the bottom of tower as thermal source, the working life of converter 1 only cannot be ensured by existing radiating mode, now will change the radiating mode of existing converter 1, together with whole with cooling system for the air outlet of converter 1, converter 1 is linked to be cold cycling body by duct set 2 and plate type heat exchanger 6, heat also can be concentrated into duct set 2 by other power consuming devices, enter actively wind circulation, good cold and hot exchange is formed in making airtight tower and outside tower, improve the working environment at the bottom of whole tower.
