Description
Technical field
The utility model relates to a kind of wind generating set engine room structure that is beneficial to heat radiation, belongs to technical field of wind power generating equipment.
Background technique
Along with the pressure increase of energy and environment, clean reproducible new energy and be subjected in recent years generally paying attention to.In all kinds of green energy resources, wind energy is one of tool business potential, most active renewable energy sources, uses cleaning, and cost is lower, takes endless.In all kinds of new energy developments, wind generating technology is relatively ripe, and have large-scale commercial applications exploitation condition most, cost is relatively low.Therefore, utilize wind energy power to receive publicity day by day and show wide growing space.
Wind power generating set needed in the open air reliable operation 20 years, withstand various exceedingly odious weather and the very test of the wind-force alternate load of complexity, to complete machine quality and unit operation stability require high.In wind power generating set, the key equipment of wind power generating set is being contained in the cabin, as gear-box, generator etc.These key equipments can produce a large amount of heats in the fan operation process, thereby cause the temperature in the cabin too high.If deal with improperly, will bring adverse effect to the safe and stable operation of whole wind power generating set.
At present, cooling channel problem at wind generating set engine room, the normal scheme that adopts is: main thermal source-gear-box in the cabin and generator are done local individual fixed point cooling, a large amount of heats that local heat of cooling exchange produces still are expelled back in the cabin, rely on the cabin ventilating fan that the hot air in the cabin is discharged the cabin again, control the reduction cabin temperature with this.This cabin cooling channel scheme is very high to the air draft discharge capacity and the reliability requirement of cabin ventilating fan, so implementation cost is higher.But in summer during long-play, the cooling effect of this cabin cooling channel scheme is unsatisfactory.
In the patent No. is in the Chinese utility model patent of 200720071638.X, discloses a kind of wind power generator main cooling system.This system comprises generator heat exchanger, gear-box heat exchanger, gear-box thermostat valve, generator thermostat valve, primary cooler and coolant pump, primary cooler Heat sink dimensions length in this system is bigger by 1%～2% than the length of original Heat sink, thickness is bigger by 2%～3% than the thickness of original Heat sink, width is constant, therefore improve heat dissipation potential, reduced cost.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of novel wind generating set engine room structure.This engine room structure can significantly improve the cooling effect and the cooling reliability in cabin.
For realizing above-mentioned purpose, the utility model adopts following technological scheme:
A kind of wind generating set engine room structure that is beneficial to heat radiation is characterized in that:
Have the special-purpose ventilation ducts of a plurality of local coolings in described engine room structure, the heat exchanger of the main thermal source in an end of the special-purpose ventilation duct of described local cooling and the cabin is connected, and the other end connection is arranged on the opening on the engine room cover 2.
Wherein, described main thermal source is respectively gear-box 3 and generator 4.
Be provided with the inlet of cool exterior air at the interface gaps place of air guide sleeve 1 and engine room cover 2.
Also be provided with the inlet of cool exterior air in the engine room cover 2 and the interface gaps of tower tube 9.
Wind generating set engine room structure provided by the utility model is directly discharged the cabin to a large amount of heats by special-purpose ventilation duct, has avoided the air of this part heat preheating engine room inside, improves the cabin cooling effect greatly.Owing to avoided the cabin atmosphere preheating,, improved the operational reliability of whole wind power generating set so alleviated the operating load of cabin ventilating fan.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the schematic representation of wind generating set engine room structure provided by the utility model.
Wherein, 1 is air guide sleeve, and 2 is engine room cover, and 3 is gear-box, and 4 is generator, and 5 is the gear-box heat exchanger, and 6 is the gear-box ventilation duct, and 7 is the hydro-generator ventilation pipeline, and 8 is the cabin ventilating fan, and 9 is the tower tube.
Embodiment
In order to overcome the defective of cooling channel poor effect in cabin in the existing wind power generating set, the utility model provides a kind of novel wind generating set engine room structure.In this engine room structure, added the special-purpose ventilation duct of local cooling specially.The heat exchanger of the main thermal source in one end of this special use ventilation duct and the cabin is connected, and the other end connects the opening that is arranged on the engine room cover 2.Through this special-purpose ventilation duct, high hot air flow can directly be discharged outside the engine room cover 2.Wherein, at two big main thermal source-gear-box 3 and generators 4 in the cabin, the heat that gear-box lubricating and cooling system and 5 heat exchanges of gear-box heat exchanger are produced, airtight pipeline by the nacelle top special use is directly discharged the cabin, and generator cooling system afterbody exchanged heat is directly discharged the cabin by the airtight pipeline of cabin afterbody special use.To other the main thermal source in the cabin, the special-purpose ventilation duct of similar local cooling can be set too.
As shown in Figure 1, in wind generating set engine room, two big main thermals source are respectively gear-box 3 and generator 4, and the heat exchanger 5 of gear-box is finished the cooling to gear-box, and its a large amount of exchanged heats are directly discharged outside the engine room cover 2 via the gear-box ventilation duct 6 of special use.The exchanged heat that generator 4 produces is directly discharged outside the engine room cover 2 via hydro-generator ventilation pipeline 7.In Fig. 1, arrow A represents that outside air enters engine room cover 2, and arrow B is the hot air exhaust airstream, and arrow C is cabin ventilating fan 8 air draft negative pressure.The cool air of nacelle exterior enters engine room cover 2 via the interface gaps of air guide sleeve 1 and engine room cover 2 respectively, perhaps enter engine room cover 2 via engine room cover 2 and tower tube 9 interface gaps, under the suction function that ventilating fan 8 air drafts in cabin are produced, form cooling blast at gear-box 3 and generator 4 surfaces.
Cool off special-purpose ventilation duct by above-mentioned part, can directly discharge the cabin to a large amount of heat exchange waste heats.On the other hand, by the lasting air draft of cabin ventilating fan, form cooling blast on the main thermal source surface in cabins such as gear-box and generator, by high hot air flow and low-heat airflow split ventilation, thereby realize high-efficiency reliable cabin cooling channel, reach the purpose of improving the cabin cooling effect.
