Description

Multi-row wind power cabin heat dissipation device

Technical Field

The utility model relates to the technical field of wind power generation, in particular to a multi-row wind power cabin heat dissipation device.

Background

In the running process of the wind driven generator, a large amount of heat is released in the process that the energy is converted into mechanical energy by wind energy and is further converted into electric energy, the electronic equipment is easy to lose efficacy and even fire disaster occurs at the over-high cabin temperature, the wind power conversion efficiency is reduced due to the over-high cabin temperature, and in order to control the temperature in the cabin within a reasonable level, a water cooling system is arranged in the cabin (a motor, a frequency converter, a speed increasing box and the like), and the generated heat is absorbed by the water cooling system to realize cooling. The water temperature of the water cooling system is increased, the high temperature water enters the radiator outside the engine room through the pipeline, the water and the air perform convection heat exchange in the radiator, heat is taken away by the outside air, and the water temperature is reduced, so that the water cooling system continuously cools the engine room.

At present, most of the outside cabin radiator is arranged to perform passive heat dissipation, active heat dissipation and active and passive combined heat dissipation in a top front-facing wind tiling mode. Passive heat dissipation relies only on natural convection of external air to achieve heat dissipation. The active heat dissipation utilizes a fan to conduct forced convection heat exchange, and the heat dissipation is achieved by controlling the wind speed and the wind quantity. The radiator adopting passive heat radiation is arranged above the engine room and is perpendicular to the wind direction, and natural convection is carried out by means of air so as to realize heat radiation. Compared with a radiator adopting passive heat dissipation, the radiator adopting active heat dissipation is further provided with an active cooling fan, and can realize heat dissipation by controlling the wind speed and the wind quantity of the cooling fan.

Passive heat dissipation and active heat dissipation have advantages and disadvantages respectively. The passive heat dissipation does not need to be provided with a cooling fan, natural convection is utilized for heat dissipation, the space occupied by the radiator is reduced while the electric energy consumption and the cost are reduced, and the space utilization rate of the top of the engine room is improved. However, passive heat dissipation cannot effectively control the heat dissipation effect, is greatly affected by the environment, and has poor heat dissipation effect in high-temperature and high-heat areas. The wind speed and the wind quantity of the cooling fan can be correspondingly adjusted according to the cabin temperature by active heat dissipation, and the temperature can be kept in a relatively fixed range, but the cooling fan is additionally arranged.

At present, most of the outside cabin radiator is arranged to perform passive heat dissipation, active heat dissipation and active and passive combined heat dissipation in a top front-facing wind tiling mode. The radiator is flatly laid on the top of the engine room, and is cooled by natural wind or forced fans. With the wind driven generator entering the era of large megawatts (more than 8 MW), the heat productivity of large parts in the engine room is greatly increased, and the heat dissipation capacity requirement of the water cooling system is correspondingly improved. The radiator is increased in height and width direction due to the increase of the heat dissipation capacity requirement, but the available space at the top of the engine room is limited, and the transportation pressure with limited height and width is increased continuously, so that the arrangement mode of the radiator is required to be expanded continuously, and the space of the platform is fully utilized.

Chinese patent application number CN201611225516.1 discloses a wind generating set, a heat dissipation system and a heat dissipation control method thereof, the heat dissipation system comprises: the impeller heat dissipation device is arranged in a cabin of the wind generating set, and hot air in a hub of the wind generating set is introduced into the impeller heat dissipation device through the air guide pipe and exchanges heat with fluid media in the impeller heat dissipation device; and the cabin heat dissipation device is arranged in the cabin, and hot air in the cabin is sucked into the cabin heat dissipation device and exchanges heat with fluid media in the cabin heat dissipation device. However, the heat exchanger of the heat dissipation system is arranged at the top of the nacelle, and the use ratio of the space at the top of the nacelle is not high.

Therefore, how to fully utilize the space of the wind driven generator to improve the heat dissipation capability is one of the problems to be solved in the current wind driven generator.
