Accompanying drawing explanation
Fig. 1 is active second wind cooling System Working Principle figure at the bottom of wind-power electricity generation closed tower of the present invention；
Fig. 2 is active second wind cooling system layout figure at the bottom of wind-power electricity generation closed tower of the present invention.
Detailed description of the invention
At the bottom of wind power generating set closed tower, actively second wind cooling system is once circulated outside wind path and secondary fresh air by tower
Circulation wind path is constituted, and one time wind path carries out coupled and heat-exchange by plate type heat exchanger in tower, to power consumption components at the bottom of tower with secondary wind path
Dispel 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, is positioned at
Plate type heat exchanger 6 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, the fan in plate type heat exchanger 6 primary side air inlet/outlet pipeline
Under 3 and 8 couplings, one time wind path flows through plate type heat exchanger 6 inside, and First air is flowed back in tower by a wind path backwind tube 5
Environment, approach primary retirn air pipeline 5 internal heater 14.Secondary side wind path, on plate type heat exchanger 6 secondary side wind pipe 9
Under fan 7 drives, outside tower, new wind enters secondary side intake stack 10, flows through the internal secondary air channel passage of plate type heat exchanger 6, finally
Flowing out outside tower by secondary side wind pipe 9, one time wind path is coupled by plate type heat exchanger 6 with secondary wind path air
Heat exchange, 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.One it is respectively arranged with at the bottom of tower
Air themperature and humidity in temperature-humidity sensor monitoring tower.
It is illustrated in figure 2 active second wind cooling system layout figure at the bottom of wind power generating set closed tower.Full envelope is used at the bottom of tower
Enclosed designs, and 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.Converter 1 at the bottom of tower judges the start and stop of device temperature controlled fan 3,7,8 by its internal temperature sensor, at fan
After driving low-converter 1 air-out of 3,8 flows through plate type heat exchanger 6 heat radiation, cold wind comes back in tower base ring border, finally by frequency conversion
At device 1 bottom air inlet mouth 4, negative pressure suction converter 1 is internal absorbs heat, and completes a wind path circulation in tower.Plate type heat exchanger 6
Be positioned on tower two-layer platform with secondary air path pipeline 9,10, under the driving of fan 7 outside tower new wind by secondary wind path blast pipe
Porch, road negative pressure sucks after plate type heat exchanger 6 inner passage completes heat exchange with a wind path and is dispersed into by a wind path heat
In atmospheric environment.Whole tower base ring border fully seals, and the outer high humidity of tower, high corrosion air can be stoped to enter in tower, be effectively reduced
The corrosion of equipment and condensation risk in tower.Having a temperature sensor in wind collection 2, that measures power consuming devices goes out pathogenic wind-warm
Degree.
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, by board-like
Heat exchanger 6 carries out cold fluid and hot fluid heat exchange, circulation wind path air themperature in reducing once；
2) when air themperature is less than in setting in tower, open fan 3,8, close fan 7, heater 14, carry out in tower
Circulation, circulation wind path air themperature in promoting once, to improve ambient temperature in tower；
3) when in tower, relative air humidity is higher than when setting, and unlatching fan 3,8, heater 14 promotes circulation wind path in once
Air themperature, heats air in tower, to reduce the relative humidity of air in tower, reduces condensation risk.
It is one side lower ending opening that conventional converter 1 generally dispels the heat, and 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 compare in the own local environment of converter 1 that tower is low
Badly, large number quipments is arranged at the bottom of tower as thermal source, only cannot ensure the work longevity of converter 1 by existing radiating mode
Life, existing by changing the radiating mode of existing converter 1, together with whole with cooling system for the air outlet of converter 1, by frequency conversion
Device 1 is linked to be cold cycling body by duct set 2 and plate type heat exchanger 6, and heat also can be concentrated into duct set 2 by other power consuming devices,
Enter actively wind circulation, form good cold and hot exchange in making airtight tower and outside tower, improve the working environment at the bottom of whole tower.
