Description
Technical field
The present invention relates to a kind of wind power generating set heating-cooling device.
Background technique
For ensureing wind-driven generator long-term safety, steady, Effec-tive Function in various environment, cooling and the heating equipment of gear-box play key effect.
Mostly traditional in the market wind turbine gearbox cooling, heating equipment are independently to separate, heating is the electric heating case by being embedded in gear-box inside, this heating equipment efficiency is low and heating time is very long, especially under cryogenic especially obvious and this local heating mode is heated and is unevenly easy to cause that local temperature is too high causes oil deteriorate, this heating cabinet is contained in bottom gear-box, is difficult to change once damage; Traditional gear-box type of cooling has forced air cooling or Forced water cooling, forced air cooling mode is, by lubricating pump, fluid is evacuated to Heat sink, by the outside heat extraction of powerful fan, this type of cooling inefficiency, and fan energy consumption and noise are very large in cooling, Forced water cooling mode will increase cooling water pipeline, circulating water pump, radiating fin, expense and volume increase greatly, and the energy consumption that is in operation equally is very large, last cooling liquid needs periodic replacement, adds maintenance difficulties and cost.It is very low that part to enter temperature in fan engine room season, will be heat up in cabin by cabin heating cabinet when people enters work.Such inefficiency and energy waste.Some areas relative moisture is larger, because day and night temperature impact can make water vapour reach dew point condensation, affects fan operation.
Summary of the invention
The technical problem to be solved in the present invention is the cooling of existing wind turbine gearbox, mostly heating equipment is independently to separate, heating equipment efficiency is low, heating time long, maintenance difficult, chiller efficiency is low, power consumption large and in cooling fan noise very large, cooling liquid needs periodic replacement, adds maintenance difficulties and cost.

At low ambient temperatures, wind power generating set, can not be grid-connected immediately often because lubricating oil temperature is lower than normally opening machine temperature 10 degree, therefore need by oil pump low temperature fluid bottom gear-box to be evacuated in heating cabinet to heat, again the oil circulation after heating is discharged in gear-box, realizes circulating-heating; When wind power generating set is normally run, gear-box can produce a large amount of heat, make Lubricating Oil liquid temp increase, when oil liquid temperature reaches 75 degree, blower fan will give the alarm, and arriving 80 degree will directly shut down, for ensureing that blower fan is efficient, stable, safe operation, heat in lubricant oil need be derived; Because in fluid and cabin, air exists the temperature difference, therefore, by gravity assisted heat pipe, oil liquid temperature can be led in cabin.The present invention adopts isolation cycle to heat and temperature-controllable, fluid and the large efficiency of heating surface of heater contacts area high, avoid that local heating is uneven causes excessive temperature differentials; Adopt gravity assisted heat pipe with fin, cooling effectiveness is high, and response is fast, does not need additionally to provide the energy, and cooling procedure reduces without the need to pumping plant and radiation fan running noises, and comfort level increases.Gravity assisted heat pipe is prior art, and current gravity assisted heat pipe heat transfer efficiency is high, and uses more and more extensive without the need to additional energy source actuation techniques is ripe at heat exchange mechanism.All temperature transducer is provided with in the import and export of heating cabinet and gear-box inside, can according to import and export and gear-box interior oil liquid temp, regulating and controlling heating cabinet power and oil pump input speed.
Normally run for preventing the too high generator that affects of temperature in cabin, engine room cover top above gear-box is provided with adjustable scavenge port, engine room cover afterbody is provided with adjustable ventilating fan that can be public with generator cooling fan, engine room cover is inside and outside respectively establishes a temperature transducer, described temperature transducer connects the control centre of peripheral hardware, and control centre regulates ventilating fan speed and scavenge port size.Regulate ventilating fan and scavenge port size in cabin by temperature sensor feedback temperature outside temperature transducer in cabin and cabin, control cabin and ambient air exchange velocity make wind built-in temperature maintain blower fan optimum Working.This kind of design can continue heat supply to engine room inside, avoids day and night temperature to cause dew condensation phenomenon greatly; In addition, the present invention can make to form heat exchange between air and gear-box fluid in cabin, can ensure that in cabin, temperature can not be too low without the need to extra heating by regulating cabin scavenge port and ventilating fan in winter.
For ease of maintenance, bottom heating cabinet, be also provided with the drain tap of band oil drain valve.This design, fluid in heater of being convenient to release when safeguarding.
As a modification of the present invention scheme, aforementioned temperature sensor all adopts PT100 temperature transducer.
For being convenient to maintenance further, the horizontal hierarchal arrangement of the heating pipe in heating cabinet.Uniform heating pipe is convenient for changing.
As a modification of the present invention scheme, described gravity assisted heat pipe adopts the heat pipe with thermal diode and thermal switch, its only in evaporator section temperature higher than 40
oability one-way heat conduction during C.
For improving radiating efficiency further, the evaporator section of aforementioned gravity heat pipe and liquid level inclination angle are 75-80 °, and evaporator section at least 2/3 stretches into lubricant oil inside.Such layout makes the radiating efficiency of heat pipe own maximize the use on the one hand, also increases long-pendingly with air contact surfaces to improve radiating efficiency, and can regulate radiating fin spacing and can also ensure that fin temperature is more than condensation is put.
Advantage of the present invention is: the present invention adopts isolation cycle to heat and temperature-controllable, fluid and the large efficiency of heating surface of heater contacts area high, avoid that local heating is uneven causes excessive temperature differentials; Heating pipe is distributed in upper gear case's heating cabinet to be changed conveniently; The present invention cools and adopts gravity assisted heat pipe with fin, and cooling effectiveness is high, and response is fast, does not need additionally to provide the energy; Cooling procedure reduces without the need to pumping plant and radiation fan running noises, and comfort level increases; The present invention can continue heat supply to engine room inside, avoids day and night temperature to cause dew condensation phenomenon greatly; The present invention can make to form heat exchange between air and gear-box fluid in cabin, can ensure that in cabin, temperature can not be too low without the need to extra heating by regulating cabin scavenge port and ventilating fan in winter.
