DISPOSITIF DE REFROIDISSEMENT DE FOND DE TOUR POUR UNITÉ DE GÉNÉRATEUR D'ÉNERGIE ÉOLIENNE, ET PROCÉDÉ DE COMMANDE

摘要

A tower bottom cooling device for a wind power generator unit, and a control method. The tower bottom cooling device comprises a tower frame (1) and a radiator (2). A main air duct is disposed in the tower frame (1), and the radiator (2) is disposed in the main air duct. A first fan (6) is disposed in the main air duct. Air in the main air duct is driven by means of the first fan (6) to flow to cool the radiator (2). The main air duct and the outer environment of the tower frame (1) form an open cycle. In the tower bottom cooling device, the radiator is disposed in the tower frame, and accordingly the integrity of a heat dissipation system can be improved; and for an offshore unit, the construction cost of a platform outside a foundation can be reduced, and the time needed for offshore hoisting can be shortened. In addition, the number of holes that need to be formed to allow water inlet pipes, water outlet pipes and cables on the tower frame to penetrate out and the follow-up sealing problems can be reduced.
