Research on the start-up of close-loop self-circulation evaporative cooling system of large electrical equipment

With the development of large electrical equipment, more and more cooling technologies are introduced to deal with the large amount of heat produced by the consumption. Close-loop self-circulation (CLSC) evaporative cooling technology is a newly developed technique for the cooling of the large electrical equipment. In certain circumstances, the air-cooling condenser is used as the secondary cooler in the evaporative cooling system of large electrical equipments. This paper mainly deal with the start-up of the CLSC evaporative cooling system, experiments and numerical simulations are carried out separately, and the results show that the structure of the inlet has great affect on the start-up of the evaporative cooling system. A reasonable structure can do great help to the start-up and the restart of cooling system.

An investigation on air cooling condenser of the close-loop self-circulation evaporative cooling large wind power generator

As a widely used clean and renewable energy, the wind power has attracted the attention of all nations in the world. The application of evaporative cooling technology in the cooling method of large wind power generator is a new attempt in the discovery of wind power energy. This paper mainly discusses the air cooling condenser with frequency converted axial fan which is adopted in the natural temperature close-loop self-circulation evaporative cooling system of large wind power generator. Some key problems which puzzling the people in the designation and running of the evaporative cooling system is also introduced here. All these will do great help to the development of the evaporative cooling large wind power generator
