Please refer to fig. 1, which is a heat dissipation air duct structure of an air cooling system of a generator in the present invention.
The heat dissipation air channel structure comprises an air supply channel 21 for conveying cold air into the generator 10, an air return channel 23 for outputting hot air from the generator 10, and a heat exchanger 22; wherein, the air inlet of the heat exchanger 22 is communicated with the air return duct 23, and the air outlet is communicated with the air supply duct 21. The hot air delivered from the generator 10 is cooled by the heat exchanger 22, and then the cold air is delivered back into the generator 10 through the air supply duct to cool the stator and rotor coils of the generator. Specifically, the heat exchanger 22 may be a water-cooled heat exchanger or other heat sink, and it should be understood by those skilled in the art that any cooling device capable of cooling hot air may be used as the heat exchanger 22, and is not limited in particular.
Further, in order to increase the heat dissipation performance of the generator 10, a fan may be disposed at the air blowing duct 21 or at the rotor of the generator, so as to further increase the heat exchange efficiency of the air cooling system.
Wherein, the air return duct 23 is provided with an air exchange opening (not numbered in the figure), the air exchange opening is communicated with the air outlet duct 30, and the air outlet duct 30 is communicated with the outside; for conveying a portion of the hot air to the outside of the generator, reducing the temperature of the hot air entering the heat exchanger 22.
Wherein, the return air duct 23 is further provided with a fresh air inlet (not numbered in the figure), the fresh air inlet is communicated with the fresh air duct 40, and an air inlet fan 41 for sending fresh air into the fresh air duct 40 is arranged at an air inlet (not numbered in the figure) of the fresh air duct 40; the fresh air duct 40 and the air intake fan 41 can draw and convey fresh air from outside into the air cooling system, thereby further reducing the temperature of the hot air entering the heat exchanger 22.
Wherein the outlet is located further from the inlet of the heat exchanger 22 than the fresh air inlet; because the wind direction of the air supply of the fresh air duct 40 is opposite to the wind direction of the air outlet duct 30, based on the wind direction of the inlet and outlet and the collision of the cold and hot air, a rotating airflow can be formed at the air inlet of the air return duct 23 close to the heat exchanger 22, so that the hot air and the fresh air are fully mixed and then enter the air inlet of the heat exchanger 22.
Furthermore, an exhaust fan 31 is further arranged at an outlet of the air outlet duct 30, and is used for discharging part of hot air in the air return duct 23 to the outside; the exhaust fan 31 can increase the hot air exhaust efficiency.
Furthermore, the pipe diameter of the air outlet duct 30 is smaller than that of the fresh air duct 40; the power of the air intake fan 41 is greater than that of the air exhaust fan 31. By designing the pipe diameters of the air outlet duct 30 and the fresh air duct 40 and the powers of the air inlet fan 41 and the air exhaust fan 31, the fresh air inlet volume can be larger than the hot air outlet volume, so that the air pressure in the generator 10 is slightly larger than the external air pressure, and the hot air in the generator is discharged outwards through each gap; meanwhile, the fresh air inlet is closer to the heat exchanger 22 than the air outlet, so that the fringe of the rotating air flow can be further increased, and the mixing of cold air and hot air is improved. Furthermore, the distance between the air outlet on the air return duct 23 and the fresh air inlet is greater than 0.5 m.
Furthermore, a filter device 42 is further disposed at the position of the air inlet of the new air duct 40, and the filter device 42 includes a filter screen and a desiccant. The filter device 42 can reduce the ingress of moisture and dust into the interior of the generator 10, protecting the useful life of the generator 10.
Furthermore, the outside of the fresh air duct 40 is covered with a heat insulation layer, so as to further ensure that the temperature of the fresh air is not affected by the temperature of the environment of the building where the generator 10 is located, because the temperature inside the building where the generator 10 is located is generally higher. Furthermore, the position of the air inlet of the new air duct is arranged outside the building where the generator is located.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
