Embodiment
Describe in detail the heat-removal system of the wind power generating set of the utility model embodiment is capable below in conjunction with accompanying drawing.
As shown in Figure 1, in embodiment of the present utility model, for convenience of description, the heat-removal system of a kind of wind power generating set is provided, is mainly used in as the radiator (needing the parts of heat radiation to be referred to as radiator by all below) in wind generating set engine room 20 and/or tower cylinder 21 provides heat radiation.
Heat-removal system comprises the first heat dissipation channel. First heat dissipation channel comprises inlet section, cabin 20 and outlet section. Wherein, inlet section is arranged on the oar side (namely near the side of pitch-controlled system in cabin 20) in cabin 20, specifically, there is gap between pod and generator and between pod and blade root respectively, and ambient atmos enters by these gaps. It is provided with engine room foundation in cabin 20, engine room foundation comprises bottom and the arc-shaped cover in cabin 20, and the internal space in cabin 20 is separated into the first area (with arc-shaped cover institute region bottom cabin) near tower cylinder 21 top and the 2nd region away from tower cylinder 21 top (removing the region outside first area in cabin 20) by engine room foundation. Outlet section is arranged on the bottom in the cabin 20 of first area, namely on engine-room platform, it may be preferred that outlet section is arranged on the bottom in the cabin 20 away from pitch-controlled system. Outlet section place is provided with the first fan 8 (axial fan), for air-flow provides power. So, first area in inlet section, cabin 20, and outlet section just defines the first heat dissipation channel of heat-removal system, aforesaid first heat dissipation channel includes radiators all in cabin 20 substantially, and under the space of first area limits, airflow circulation situation in first heat dissipation channel is better so that the first heat dissipation channel can utilize the wind comes from of inlet section (oar side) it to be dispelled the heat more efficiently. Its principle of work is as follows: when heat-removal system works, first fan 8 of outlet section is opened, extraneous cooling gas is forced to enter wheel hub from the blade root of pitch-controlled system and the gap of pod and the gap of pod and generator, and cool the axle system internal surface of moving axis (generator determine) of the change oar cabinet in wheel hub, generator successively, cooling the frequency-charger cabinet 12 in first area, cabin 20 and cabin cabinet 11 again, the gas after cooling is drained in tower cylinder 21 by outlet section. This is the first heat dissipation channel cooling path, and the radiator that the first heat dissipation channel is mainly in wheel hub, generator and cabin 20 provides heat radiation.
Heat-removal system also comprises the 2nd heat dissipation channel, and the 2nd heat dissipation channel can be the radiator in cabin 20 and/or tower cylinder 21 and implements to dispel the heat separately (not by the impact of the first heat dissipation channel). 2nd heat dissipation channel includes air port, enters air port and is connected with one end of the first airduct 6, and the other end of the first airduct 6 is for going out air port. Wherein, enter air port and it is arranged on the sidewall of cabin 20 and/or tower cylinder 21, and enter air port place and be provided with the 2nd fan 10, to suck from outside by external world's cooling gas, and by the first airduct 6, radiator is dispelled the heat.
Specifically, the position that arranges entering air port is determined according to the demand of practical situation, it is necessary to when the radiator in cabin 20 is dispelled the heat separately by the 2nd heat dissipation channel, enters air port and can be arranged on the sidewall in cabin 20; When needing the 2nd heat dissipation channel to be dispelled the heat by the radiator in tower cylinder 21 separately, enter air port and can be arranged on the sidewall of tower cylinder 21. Such as, when the radiator in tower cylinder 21 is dispelled the heat separately by the 2nd heat dissipation channel, the air port that enters of the 2nd heat dissipation channel is arranged on the sidewall of tower cylinder 21, and make the 2nd heat dissipation channel go out air port directly towards the radiator in tower cylinder 21; Again such as, when the 2nd heat dissipation channel needs to be dispelled the heat by two radiators in tower cylinder 21 simultaneously, the going out air port and can be set to two of 2nd heat dissipation channel, respectively towards two radiators in tower cylinder 21, simultaneously for two radiators in tower cylinder 21 carry out air blast, thus to reach the effect of heat radiation. Certainly, it is also possible to according to the practical situation needs of radiator, design the heat-removal modalities of the first heat dissipation channel, it should not when being limited to the situation cited by the utility model embodiment.
Discharge smoothly for ease of the hot gas physical efficiency after first, second heat dissipation channel uses, heat-removal system also comprises the air draft mouth being arranged on tower cylinder 21 sidewall, and it is located at the three fan 3 at air draft mouth place, the effect of three fan 3 be heat radiation in tower cylinder 21 after hot gas sucking-off, and be discharged into the external world. Certainly, the quantity of air draft mouth and fan can be one, it is also possible to is multiple, specifically arranges according to the radiating effect under actual condition, also unrestricted at this.
The heat-removal system of the wind power generating set that above-described embodiment provides, come because adopting the first separate heat dissipation channel and the 2nd heat dissipation channel to be dispelled the heat by the radiator in cabin in wind power generating set 20 or tower cylinder 21 respectively, under avoiding traditional concentrated or unified heat radiation mode, part radiator affects by the hot blast after heat radiation in heat dissipation channel, can not get the problem of fully heat radiation.
For the heat dissipation problem of special heat-radiating body effectively solved in cabin 20 or tower cylinder 21, for example, being power cable 4 for radiator, because of service requirements, power cable 4 is layout from cabin 20 usually, dangles to tower cylinder 21 always. In use, power cable 4 is positioned at cabin 20 position and the torsion cable position being positioned at tower cylinder 21 generate heat more serious usually. Being below simplified illustration, the high hot spot that power cable 4 is positioned at cabin 20 is the first hot-zone A, and power cable 4 is positioned at the high hot spot turning round cable place the 2nd hot-zone B. And the cooling gas come in from the inlet section of the first heat dissipation channel is when flowing to the power cable 4 in cabin 20, by radiator (the change oar cabinet in wheel hub, the axle system of generator along road, frequency-charger cabinet 12) heating, remove the power cable 4 first hot-zone A that cooling temperature is higher again, effect will be very undesirable, and probably not have the effect of cooling.
For solving the heat dissipation problem of power cable 4, the air port that enters of the 2nd heat dissipation channel is arranged on the sidewall away from oar side in cabin 20, preferably, it is arranged on the afterbody of cabin 20, and make the first hot-zone A that the first airduct 6 surrounds after the arc-shaped cover of engine room foundation, and the 2nd hot-zone B cooling gas being drained in tower cylinder 21. So, 2nd heat dissipation channel is under the rotation of the 2nd fan 10 (axial fan), directly sucking cold air from the external world, dispelled the heat by the 2nd hot-zone B after being dispelled the heat by the first hot-zone A by the first airduct 6 (heat insulation airduct) again, the gas after dispelling the heat the most at last drains into tower cylinder 21. Thus efficiently solve the heat dissipation problem of special heat-radiating body power cable 4. In order to reach the cooling requirements of key area further, also can offer separately into air port and airduct on tower cylinder 21 sidewall again so that it is separately the 2nd hot-zone B is dispelled the heat, to guarantee to reach the cooling requirements of power cable Niu Lan district (the 2nd hot-zone B).
Except above-mentioned radiator is that power cable this kind of special heat-radiating is external, radiator can also be that other comprise the radiator of two hot-zones, the principle of its heat radiation mode is identical with the principle that power cable dispels the heat, namely arranging one article of the 2nd relatively independent heat dissipation channel is its heat radiation separately, no longer repeats at this.
In order to improve the radiating effect of heat-removal system further, the outlet section place of the first heat dissipation channel is provided with the 2nd airduct 7. The exit end of the 2nd airduct 7 is towards the stage casing tower barrel platform of tower cylinder 21, and is positioned at above the tower barrel platform of stage casing. Accordingly, stage casing tower barrel platform below the exit end of the 2nd airduct 7 is provided with perforate. The effect of the 2nd airduct 7 is that the hot gas by outlet section is discharged is drained in the middle part of tower cylinder 21, removes to affect the 2nd hot-zone B of power cable 4 when avoiding the hot gas discharged from outlet section to flow downward again. So, the heat radiation gas of the first heat dissipation channel is driven in the middle part of tower cylinder 21 by the 2nd airduct 7 after flowing out from outlet section, and continues discharge downwards eventually through the perforate in tower cylinder 21 middle deck.
Considering safety operation problem, the outlet section place of the first heat dissipation channel is provided with the top that the first turbogrid plates 9, first turbogrid plates 9 are positioned at the first fan 8. The effect of the first turbogrid plates 9 is, cold air both can have been allowed to pass through, and guarantees that again personnel are when operating the 2nd airduct 7, are unlikely to fall to tower cylinder 21 from outlet section and security incident occurs. In addition, because the first turbogrid plates 9 are positioned at the top of the first fan 8, moreover it is possible to prevent the first fan 8 that corresponding instrument falls on engine-room platform. Tapping on the tower barrel platform of stage casing is provided with second gate lattice plate 5, and second gate lattice plate 5 is equally also play effect that is ventilative and Accident prevention generation, no longer repeats at this.
In order to effectively be discharged by the hot gas of the first heat dissipation channel and the 2nd heat dissipation channel, air draft mouth and three fan 3 on tower barrel are arranged on above the tower cylinder door 2 bottom tower cylinder 21. During use, under the rotation of fan, (fan drives the flowing of the gas in tower cylinder 21, thus the gas driving whole wind power generating set flows), by in the middle part of tower cylinder 21 discharge the quick sucking-off of hot gas and drain into the external world by air draft mouth, thus complete a totally circulation of the heat-removal system of whole wind power generating set, reach the object that whole wind power generating set is dispelled the heat. On the other hand, three fan 3 can also extract the hot gas in master control layer 13, and avoids the current transformer 1 that hot gas is incorporated into lower section, can not have influence on the heat radiation (heat-removal system that current transformer 1 has it independent) of current transformer 1.
The heat-removal system of the wind power generating set that the utility model embodiment provides, by setting up the first separate heat dissipation channel and the 2nd heat dissipation channel in wind power generating set, the multiple high heating position of the bigger radiator of thermal value or radiator can be cooled targetedly, and because of two heat dissipation channels separate, it is independent of each other, so under effectively prevent traditional concentrated or unified heat radiation mode, part radiator affects by the hot gas in heat dissipation channel, can not get the problem of fully heat radiation.
The utility model also provides a kind of wind power generating set, comprises above-mentioned heat-removal system, also comprises master control system, and master control system controls the first heat dissipation channel and/or the 2nd heat dissipation channel of heat-removal system as required. Specifically, master control system pre-sets steering logic, controls separately the startup of the 2nd heat dissipation channel as required, and power cable 4 or other radiator in need is implemented separately heat radiation. Or say, when the radiator temperature detected in the first heat dissipation channel by sensor is too high, reports to the police or strengthened the specific heat load of the first heat dissipation channel by regulating and controlling first fan 8. This wind power generating set can save energy to greatest extent, make the heat-removal system of wind power generating set more intelligent.
The heat-removal system of the wind power generating set that the utility model provides has following technique effect:
The heat-removal system of the wind power generating set of the utility model embodiment is by setting up two independent heat dissipation channels, the different heat region of the radiator that thermal value of can dispelling the heat separately is bigger or radiator, make the main heat sink body in wind power generating set can obtain balanced heat radiation, and avoid influence each other between radiator (part radiator affects by the hot blast after heat radiation in heat dissipation channel, can not get abundant heat radiation). On the other hand, the heat radiation mode of the heat-removal system of this wind power generating set is simple, run, maintenance all more convenient, and cost is lower, practical. Compare the heat-removal system of traditional wind group, effectively prevent the risk of the various heat-eliminating medium leakage that tradition cooling system brings when applying.
The above; it is only embodiment of the present utility model; but protection domain of the present utility model is not limited thereto; any it is familiar with those skilled in the art in the technical scope that the utility model discloses; change can be expected easily or replace, all should be encompassed within protection domain of the present utility model.
