Abstract
The invention discloses a marine tidal-current energy generator outer wall ventilation heat exchange cooling structure. A generator is arranged on the front part of a cabin; a fan is arranged on the front end of a main shaft of the generator; a speed increaser is connected to the rear end of the main shaft of the generator; a cooling interlayer is of an interlayer structure formed by a cabin outer wall and a cabin inner wall; a wind screen is arranged between an outer shell of the generator and the cabin inner wall; the interlayer on the rear part of the speed increaser is provided with a hot air inlet; and the interlayer on one side of the fan is provided with a cool air outlet. According to the structure, cold blast rate can be effectively utilized, the escape is reduced, the radiating efficiency of the generator is improved, and the characteristic that cooling air used for the speed increaser has higher temperature is utilized, so that the air after cooling the generator can be used for cooling the speed increaser and other equipment.
Description
Technical field: the present invention relates to a kind of trend can generator outer wall ventilation heat exchange cooling structure.
Background technology: the generator bay of trend ability unit partly is operated in b.s.l.; The loss that the loss that speed increaser in the work (gearbox) produces, generator produce; If can not adopt effective heat exchange means to cool off, then long-term stability, the safe operation of trend ability unit can't realize.In the seabed (about 30～50 meters depth of waters) and away from the working region of seashore (more than 500 meters) under water permanent plant cool off, need to consider the corrosivity and the halobiontic tack of seawater.Therefore use external water-hydrothermal exchange cooler construction to realize,, more can't adopt the direct heat radiation cooling structure of wind-powered electricity generation form because the equipment in the whole cabin all can not be exposed in the environment of humidity, salt fog.
Summary of the invention: the objective of the invention is to disclose a kind of trend ability generator outer wall ventilation heat exchange cooling structure that can effectively utilize cold blast rate, reduce the radiating efficiency that leaks, improves generator.Technical scheme of the present invention is: a kind of trend ability generator outer wall ventilation heat exchange cooling structure; Generator is installed in the front portion, cabin, and the generator shaft front end is installed fan, and the generator main shaft rear end connects speed increaser; Cooling sandwith layer constitutes sandwich by cabin outer wall, cabin inwall; Deep bead places between generator casing body and the cabin inwall, and the interlayer at speed increaser rear portion has hot air inlet, and the interlayer of fan one side has the cold wind air outlet.
The course of work of the present invention: fan provides whole wind path circulation power, and it is connected with generator through little gearbox, is the self-driven type formula; The generator one section is connected on the fan, and one section is connected on the speed increaser, and the effect of keeping out the wind of deep bead down; The cold wind that fan blows out all passes through in generator; Cooled electric generator also gets into the engine room inside zone, and through calculating, the air themperature in engine room inside zone is in 45 ℃; Condition satisfies the cooling requirement of speed increaser; Hot blast behind generator, the speed increaser, hot air inlet get into cooling sandwith layer, and cooling sandwith layer is made up of the heat exchange by the seawater outside completion of cabin outer wall and the cabin of the hot-air that gets into interlayer cabin outer wall, cabin inwall.Cold air after the completion heat exchange under the suction function of fan, continues to get into generator through the cold wind air outlet, forms the wind path circulation.
Air in the generator bay body of the present invention is airtight, the circulating ventilation cooling; Be provided with the totally-enclosed cabin body of heat exchange vent passages interlayer, be used for the seawater outside the hot blast of taking away equipment loss and the cabin is carried out heat exchange, be equivalent to air-water heat exchange cooler; Use provides the fan of air circulation power, is used to provide cold wind to take away the function of the thermal losses of equipment such as generator, speed increaser, and hot blast ensures air quantity through the function of ventilation interlayer and seawater heat exchange; Utilization is as the generator of the part among the vent passages, and generator can effectively utilize cold blast rate as the part of vent passages, and minimizing leaks, and improves the radiating efficiency of generator; Utilize the higher characteristics of the spendable cooling wind-warm syndrome of speed increaser, cool off miscellaneous equipments such as speed increaser with the wind behind the cooled electric generator.
