Abstract

L'invention concerne un dispositif (1) générateur d'énergie doté d'un dispositif d'expansion à tige à tarière et destiné à être utilisé dans un cycle de Rankine organique. Le dispositif (1) de génération d'énergie comprend un carter semi-fermé ou entièrement fermé. Un dispositif d'expansion à tige à tarière et un générateur (101) sont disposés dans le carter. Un rotor (102) du dispositif d'expansion à tige à tarière est fixement connecté au rotor du générateur. Le générateur (101) est entraîné pour produire de l'électricité par la rotation du rotor (102) du dispositif d'expansion à tige à tarière. Une entrée de gaz (107) et une sortie de gaz (108) du dispositif d'expansion à tige à tarière sont pratiquées dans le carter. Un écoulement de gaz qui entre dans le carter par l'entrée de gaz (107) et est déchargé par la sortie de gaz (108) du dispositif d'expansion, traverse le générateur (101) de manière à refroidir le générateur (101). Le dispositif (1) de génération d'énergie doté d'un dispositif d'expansion à tige à tarière est semi-fermé ou entièrement fermé. Le dispositif d'expansion à tige à tarière et le générateur (101) sont disposés dans le carter sous la forme d'une seule unité. Le générateur (101) peut être un générateur synchrone ou un générateur asynchrone. Lorsque le dispositif (1) de génération d'énergie doté d'un dispositif d'expansion à tige à tarière produit de l'électricité, toute fuite d'un médium opérationnel de refroidissement peut être évitée.
