Therefore, usually knownly control the inflow of the cool air that gets into wind turbine, drop to critical value for cold responsive some parts with the temperature that prevents turbine interior by rotating speed control fan.
Yet; Be in this particular problem: for cold responsive parts with for hot responsive parts generally in the identical chamber or compartment of wind turbine, for example in pylon, cabin or chamber, be set together abreast; And at the flow velocity of cool air through the wind turbine middle chamber owing under the situation that rotation speed of the fan reduces, can't suitably guarantee the heat dissipation from heat-sensitive component is fully dispelled the heat.
Summary of the invention
Therefore; The purpose of this invention is to provide a kind of wind turbine; Can use simple device especially at this wind turbine of refrigerant latitudes control; Thereby guarantee heat sensitive wind turbine components is fully cooled off, but can room temperature not dropped under the critical temperature value of cold responsive wind turbine components.
This purpose is realized by a kind of wind turbine with the said characteristic of claim 1.Dependent claims has showed favourable design of the present invention.
Basic principle of the present invention is: the heat that has been sent by wind turbine components is heated and a part of fresh air stream of discharging fully from wind turbine as using air traditionally is recycled in the chamber of wind turbine; Thereby the inflow of cold fresh air can be confirmed by presenting the ratio of using air of getting back in the chamber; And fresh air and used air to mix, and can avoid making temperature to be low to moderate under the critical temperature of wind turbine operation and still guarantee abundant cooling simultaneously.
Description of drawings
Use and to explain in the accompanying drawings and to have especially the exemplary embodiment of preferred configuration and come to explain in more detail the present invention.In the accompanying drawing:
Fig. 1 shows the stereogram according to wind turbine of the present invention; And
Fig. 2 is illustrated in the schematic representation of the inner circulating air of wind turbine.
Embodiment
Fig. 1 shows has the especially stereogram of the wind turbine 10 of preferred configuration.Wind turbine 10 has pylon 20, cabin 30 and energy conversion unit (not shown), and cabin 30 is arranged on the pylon 20, and energy conversion unit is arranged in the cabin 30.Energy conversion unit is connected in rotor, and this rotor has three the rotor blade 50a, 50b, the 50c that are connected in hub 40 in the example shown, is unessential and in fact what rotor blades are provided for carrying out the present invention.
In order to cool off to being arranged on parts in one of them chamber of being located in the wind turbine 10, for example gear-box, bearing, hydraulic unit, rectifier, transformer, heat exchanger etc.; This wind turbine 10 also has fresh air is caused the chamber such as cabin 30 and will bring to outside device with crossing air from the outside, and this device can be taken away the heat dissipation of the wind turbine components 60 that is arranged in the cabin 30.Substitute or additionally, wind turbine 10 also can have the cooling unit that is used for identical chamber or more another chamber, for example pylon 20 or hub 40 as one.Chamber can only occupy the part area of pylon 20, cabin 30 or hub 40.
Fresh air is caused chamber and will bring to outside device and can be designed to one or more simple entrance and exit openings with crossing air from the outside, and can be additionally provided with fan and various filter.
During the course, the air-flow that guides fresh air and used air for example as mentioned below, and in Fig. 2, schematically illustrate.Cold fresh air is supplied to the parts 60 such as gear-box, motor, hydraulic pressure positioning device or heat exchanger the chamber 100 such as pylon 20, cabin 30 or hub 40 that is arranged on wind turbine 10 from the outside around the wind turbine 10.Absorb the heat dissipation that is sent by parts 60 through parts 60 or the fresh air that flows through parts 60, and as draining into external environment condition as air from the internal chamber 100 of wind turbine 10.
According to the present invention, positioning element 70 is provided at present, this positioning element 70 manually or automatically activate and will be with the part stream of crossing air, be that the part stream of the air of carrying part 60 heat dissipations draws in the chamber 100 of getting back to wind turbine 10.
Existing preferably Design Orientation element 70, thus can confirm that part stream used airborne ratio (volume) whole, and for example when when hanging down under the outdoor temperature starting device, the ratio that partly flows can be 100%.When need not to cool off, the circulation in the chamber 100 of wind turbine 10 used air to prevent that fresh air from getting into chamber 100.In the further operation and further temperature-rise period of parts; The whole ratio of using the air middle part to shunt drops to and is lower than 100% numerical value; Make and used part of air to drain into the outside, and cold fresh air is fed in the chamber 100 through the negative pressure that discharge used air to produce.Then, warm used air and the cold fresh air that gets into chamber 100 mix mutually, and when the ratio that the part as air of presenting is back flowed with suitable manner is regulated, produce the room temperature that helps equipment operation.
