Description
Technical field
The present invention relates to a kind of land high-power wind-driven generator group bottom of towe cooling system, more particularly to a kind of bottom of towe is actively
Wind-water coincidence cooling system.
Background technology
With the fast development of wind generating technology, land wind power generating set generated output progressively increases, unit operation
During the heat that produces can also step up, it is the main pyrotoxin of bottom of towe that wherein frequency converter, case, which become,.How bottom of towe thermal source is ensured
Efficiently exclude to turn into outside tower and ensure one of key issue that blower fan is normally run.
For wind power generating set, there are air-cooled and two kinds of forms of water cooling in conventional tower bottom methods for cooling, to double-fed frequency conversion
Device, when capacity is reached within 2.5MW, total power frequency inverter capacity is reached within 1.5MW, generally using air-cooled form to bottom of towe heat
Source is cooled down.After capacity is more than above-mentioned value, because caloric value is big, air-cooled form can not meet radiating requirements, therefore logical
Frequently with water cooling form.
There is respective defect in above-mentioned traditional type of cooling, for air-cooled form, and whole frequency converter all uses air-cooled form, bag
Power model, reactance inside frequency converter etc. are included, because the heat-sinking capability of air-cooled form is poor, and the heat flow density of power model
Greatly, therefore with the lifting of transducer power grade, air-cooled form will be difficult to the radiating that meets the devices such as power model, serious shadow
Ring the performance and service life of power model.Therefore, with the lifting of power grade, water cooling form turns into main flow radiating mode,
Inside current powerful frequency converter, the device of the big heat flow density such as power model, reactance generally uses water cooling form, water cooling shape
Although formula can meet radiating requirements, reliability is poor（It is perishable that seepage, pipeline easily occur for such as night cooling system）, cost it is high
It is big with maintenance difficulties.
At present, large sized unit turns into the main flow of land unit, the requirement more and more higher to cooling system.Tradition is most held
Frequency converter radiating can not be taken away by the stack effect of tower completely in the air-cooled form easily designed.For powerful frequency conversion
Device, because its caloric value is big, stack effect is difficult to effectively take away bottom of towe heat, certainly will cause bottom of towe and frequency converter excess temperature.And
Water cooling high cost in itself and Maintenance Difficulty are faced with the test in market again.

Transformer is cooled down in the cold air suction transformer of part, air and the cold sky being introduced into transformer at transformer outlet
Gas is mixed, and the air after mixing is carried in fan suction frequency converter by frequency converter, and air cooling module in frequency converter is carried out
After cooling, heated air discharge frequency converter, then the perforate and ventilating fan discharge by tower side wall are outdoor, complete active wind
SAPMAC method；
In cooling by water circulation, high temperature coolant is first transported to water-cooling unit by pumping plant in Water-cooled cabinet and cooled down, quilt
The water cooling liquid of cooling is entered after frequency converter by Water-cooled cabinet, the water cooling module in frequency converter is cooled down, heated water
Cold liquid, is again fed to water-cooling unit outside tower by pumping plant and is cooled down, and completes circulation.
Big heat flow density device is located in independent cabinet in the frequency converter, and other devices are located in another cabinet, greatly
Heat flow density device band water cooling module, whole frequency converter band air cooling module.
The big heat flow density device band water cooling module, water cooling module is the water pipe through big heat flow density device inside
Road, passes through water-cooling unit outside tower and carry out cooling by water of the inlet and outlet pipe to big heat flow density device.
The air cooling module includes perforate and fan, by two bottom of cabinet bulk perforates of frequency converter, two cabinet tops
The fan on both sides introduce outside fresh air by whole frequency converter inside, to other devices of frequency converter inside and big heat flow density device
Air-cooled cooling is carried out, the air cooled down is discharged by fan.
The beneficial effects of the present invention are：Bottom of towe active wind-water coincidence cooling system of the present invention, by adding in tower bottom
Active air cooling device is filled, the active air cooling circulation of tower bottom is realized, waterway circulating is realized by bottom of towe Water-cooling circulating.Active air cooling
Device is used to realize the temperature control to part of heat energy such as the change of bottom of towe case, frequency converters, and Water-cooling circulating is used for big in frequency converter etc.
Caloric value part temperatures are controlled, and wind-water coincidence cooling circulation be combined with each other realization to bottom of towe environment temperature and the essence of humidity
Really control.Bottom of towe wind-water coincidence cooling system makes full use of that air cooling system is stable, cost is low, water-cooling system cooling effect
Good advantage, the two is effectively combined, and the system is for lifting land high-power wind-driven generator group operational reliability, reducing into
Originally there is very great meaning.
