Detailed Description

The utility model will be further illustrated with reference to specific examples.

As shown in fig. 1, this embodiment discloses a heat dissipation system applied to a nacelle and a generator of a wind generating set, including a heat dissipation cover 1, two shutters 2 and two cooling fans 3, wherein, two heat dissipation holes are opened in the middle of the nacelle 4, one heat dissipation hole is opened at the afterbody, two heat dissipation holes are opened at the top of the housing of the generator 5, a heat exchange channel is provided between the generator 5 and the nacelle 4, the heat dissipation cover 1 is mounted at the heat dissipation holes at the afterbody of the nacelle 4 through bolts, two shutters 2 are mounted at the two heat dissipation holes at the middle of the nacelle through bolts, and two cooling fans 3 are mounted at the two heat dissipation holes at the top of the housing of the generator through bolts.

When the generator runs, a large amount of heat is generated, the two cooling fans 3 at the top of the generator 5 pump hot air out of the generator 5, at the moment, because the hot air in the generator 5 is pumped out by the cooling fans 3, negative pressure is generated in the generator 5, air in the engine room 4 enters the generator 5 through a heat exchange channel between the generator 5 and the engine room 4, the cold air entering the generator 5 is changed into hot air after heat exchange, and the hot air is discharged out of the generator 5 by the cooling fans 3, so that the generator 5 can dissipate heat through air convection and heat exchange. As shown in fig. 2, the air in the cabin 4 is pumped away by the generator 5, the external air enters the cabin 4 through the two shutters 2 in the middle of the cabin 4 and the heat dissipation cover 1 at the tail of the cabin 4, and the heat generated by the motor in the cabin 4, the cabin cabinet and other heating devices is carried to the outside of the cabin 4 through heat exchange, so that the air enters the cabin 4 from the outside of the cabin 4, enters the generator 5 from the inside of the cabin 4 and is discharged to the outside of the cabin 4 from the generator 5, and the process can take away the heat generated by the motor in the cabin 4, the cabin cabinet and other devices and the generator 5 and form air convection, so that the motor in the cabin 4, the cabin cabinet and other devices and the generator 5 work in a specified temperature range, and the safe and stable operation of the unit is ensured.

As shown in fig. 3, the heat dissipation cover 1 is connected with the engine room 4 through bolts, and two positions where the bolts are fixed are arranged, one position is located at the air inlet and distributed in the circumferential direction; the other part is positioned at the lower edge of the heat radiation cover 1 and is distributed in a straight line. The radiator cover 1 is downward opened, so that rainwater can be prevented from entering, and meanwhile, the louver or the isolation net 101 (shown in fig. 4) is arranged at the opening position of the radiator cover 1, so that small objects such as small animals or catkin can be prevented from entering the cabin 4 to cause blockage.

In order to further enhance the protection effect, small objects, dust and the like outside the cabin 4 are prevented from entering the cabin 4, the inside of the cabin 4 is kept clean, the isolation box 6 is also arranged inside the cabin 4, as shown in fig. 5, the isolation box 6 is arranged at the radiating hole at the tail part of the cabin 4 through bolts, a sealing plate 601 is arranged on the surface, opposite to the cabin 4, of the isolation box 6 (cannot be ventilated, as shown in fig. 6), isolation nets 602 are arranged on the other four surfaces, the wind is prevented from directly blowing against the isolation nets 602, the wind force is overlarge, the dust is brought into the cabin 4, the wind is directly blown onto the opposite sealing plate 601 after passing through the radiating hole, and due to the blocking effect of the sealing plate 601, the wind and the mixed dust are dispersed to the periphery, so that the wind speed is reduced, and the probability that the dust enters the inside of the cabin 4 is further reduced. The isolation net 602 can be removed periodically, the isolation net 602 is cleaned and replaced, the inside of the isolation box 6 is cleaned, and the operation and maintenance are convenient.
