Abstract

sistema e método de refrigeração externa de máquinas elétricas a presente invenção refere-se a uma máquina elétrica (10) refrigerada a ar, tal como um motor de corrente alternada, tendo um alojamento (12) contendo um eixo giratório (14) e um trajeto de refrigeração do fluxo de do alojamento tem respiradouros de refrigeração na periferia do alojamento. um sistema de refrigeração externo tendo um recinto em duto (30) é acoplado à parte externa do alojamento (12), e define um trajeto de refrigeração do fluxo de ar em duto que está em comunicação com o respiradouro de refrigeração do fluxo de ar do alojamento e o trajeto de refrigeração do fluxo de ar do alojamento. uma ventoinha de duto (32) dentro do recinto em duto (30) externa ao alojamento (12) está acoplada a e é acionada pelo eixo (14). a ventoinha de duto (32) circula o ar acima da pressão ambiente no trajeto de refrigeração do fluxo de ar do alojamento.
