Abstract
The invention discloses a nose cooling system for a wind generating set. The nose cooling system comprises an air heat exchanger I and an air heat exchanger II which are arranged inside a cabin, wherein the air heat exchanger II is arranged on a platform at the top of a tower; an inlet and an outlet for cooling air of the air heat exchanger II are formed in two sides of the top of the tower respectively; hot air is pumped into the air heat exchanger I inside the cabin through a ventilating pipe at the upper portion of a generator and exchanges heat with air coming from the outside of the cabin; and the air heat exchanger II enables air of the first-time heat exchange inside the cabin to exchange heat with external cold air for a second time. According to the nose cooling system for the wind generating set, secondary heat exchange is added at the top of the tower, so that the disadvantage of insufficient heat dissipation of the nose of a high-power wind generating set is overcome; and particularly, the cabin is separated into enclosed spaces, so that hotter air inside the tower is prevented from entering, the heat dissipation efficiency is greatly improved, the temperature inside the nose is reduced, and the service life of the to-be-cooled part is prolonged.
Description
Technical field
The present invention relates to wind-powered electricity generation field, particularly relate to a kind of head cooling system of wind power generating set.
Background technique
At present, the head cooling of wind power generating set is mainly and heat exchanger is arranged on engine room inside, the low-temperature receiver of heat exchanger carrys out the relative cool air in outside atmosphere, be arranged at the centrifugal blower on generator by the hot air of generator through external ventilation pipe in arrival engine room inside heat exchanger, the air through exchanger cooling is recycled to again in cabin.After wind power generating set electric motor power increases, the power requirements of heat exchanger is increasing, but, the limited space in cabin and powerful radiator is bulky, cannot this type of powerful heat exchanger be placed in cabin, cause temperature rise in cabin too high and cause the vitals service life reduction such as generator and bearing in head.
Summary of the invention
The object of the invention is to overcome above defect, a kind of head cooling system cooling reliable wind power generating set is provided.
Technological scheme of the present invention is, a kind of head cooling system of wind power generating set, it comprises the air heat exchanger I being arranged on engine room inside, also comprise air heat exchanger II, described air heat exchanger II is placed on tower cylinder top platform, the import of the cooling air of air heat exchanger II and outlet are separately positioned on the both sides at tower cylinder top, and the ventilation duct of hot air through generator top is extracted in the air heat exchanger I of engine room inside, carries out a heat exchange with the air from nacelle exterior; Air after an engine room inside heat exchange and cool exterior air are carried out second heat exchange by air heat exchanger II.
In order to prevent the heat in tower cylinder from entering in cabin, cabin and tower cylinder seal isolation make cabin form independently confined space by described tower cylinder top platform.
Further improve cooling effectiveness to save, the cool air source of described air heat exchanger I and air heat exchanger II all comes from the outside of wind power generating set.
Advantageous Effects of the present invention is, owing to adding second time heat exchange at tower cylinder top, overcome the defect that the heat radiation of high-power wind-driven generator group head is not enough, particularly cabin is isolated into airtight space, the comparatively hot air in tower cylinder is prevented to enter, substantially increase radiating efficiency, reduce the temperature of head inside, improve the working life of component to be cooled.
Accompanying drawing explanation
Fig. 1 is embodiment of the present invention structural representation;
Fig. 2 is embodiment of the present invention cool cycles schematic diagram.
Embodiment
