Abstract

Ce dispositif possède un ventilateur (8) actionné par le passage du fluide transmettant la température, de préférence de l'eau, qui est impulsée depuis la chaudière ou refroidisseur, de sorte qu'avec cet émetteur on force la sortie d'air par convection et une basse émission par radiation. Le ventilateur (8) est actionné par une noria ou roue (6) que l'on intercale dans le conduit de fluide. On peut appliquer ce dispositif à un radiateur classique ou à un radiateur constitué par une face frontale radiante (13) et une face arrière isolante (12) dont la paroi intérieure (12') est réfléchissante.
