Air cooler for power station

Abstract

The invention relates to an air cooler for a power station. A shell of the air cooler for the power station is square, shutters are arranged on the four side faces of the shell, each shutter is provided with a plurality of blade plates, rotating shafts are arranged at the two ends of each blade plate, gears are arranged on the rotating shafts at the same side ends of the blade plates, and the gears are connected with one movable rack in a meshed manner; and eccentric air plates are connected to the rotating shafts at the two ends of one certain blade plate, and the air plates are located outside the shell and arranged in the axial directions of the rotating shafts. According to the air cooler, self-adaption to various wind directions is realized by ingeniously utilizing the air plates, and the opening degree of the windward sides and the opening degree of the leesides of the shutters can be automatically adjusted according to the wind power, so that the air suction amount and the back pressure of a fan are kept stable, and a generator can continuously and stably run. The air cooler is simple in structure, low in cost and high in adaptability, complex control circuits and mechanisms are not needed, and the influence of transverse wind on the air cooler is well solved.

Description

technical field [0001] The invention relates to the technical field of air coolers, in particular to an air cooler for power stations. Background technique [0002] During the operation of the generator, the loss of copper and iron is converted into heat energy, and the internal heating of the generator is serious, especially the temperature of the stator winding cannot exceed 120 °C. In order to ensure the long-term continuous operation of the generator, an air cooler is needed to cool the inside of the generator. An air cooler is a heat exchange device that uses external cold air to cool down a fluid. Such as figure 1 As shown, the current air cooler is roughly in the shape of a square box, and shutters are provided around the box. The finned heat dissipation tube bundle 1 is arranged on the top of the square box, and a fan 3 and an air guide tube 2 are installed below the finned heat radiation tube bundle, and the air guide tube 2 is perpendicular to the air inlet dire...

AI Technical Summary

Problems solved by technology

Regardless of the manual adjustment type or the mechanical adjustment type, the problem to be solved is: make the opening of the louvers smaller in winter to reduce the heat dissipation effect on the finned heat dissipation tube bundle; The heat dissipation effect of the finned heat dissipation tube bundle

This is an adaptive adjustment to the ambient temperature, but there is no adaptive adjustment to the external wind
