Abstract

La présente invention concerne un générateur refroidi par air, traversé par de l'air de refroidissement pour évacuer la chaleur dissipée, l'air de refroidissement passant sur des surfaces limites (23) faisant office de surfaces de refroidissement et absorbant ainsi la chaleur de ces surfaces limites (23). Le transfert de chaleur est maximisé, avec une consommation d'air de refroidissement minimale, par le fait que les surfaces limites (23) sont pourvues de parties saillantes (24) locales réparties, augmentant la surface de refroidissement et le coefficient de transfert de chaleur. Ces parties saillantes locales sont notamment réalisées de manière avantageuse en tant que corps en forme de pyramides ou de pyramides tronquées (24, 26, 29).
