Abstract

L'invention vise à proposer un échangeur de chaleur en spirale ayant au moins deux plaques de transfert de chaleur en forme de bande enroulées en spirale. Des goujons sont disposés de façon continue en une forme d'étagère à travers un espacement prédéterminé à un espace prédéterminé par rapport aux bordures d'extrémité d'ouverture individuelles des deux plaques de transfert de chaleur en forme de bande. Un joint d'étanchéité en forme de corde est monté et enroulé en spirale sur les goujons, et est fixé par un élément de recouvrement de telle sorte que l'échangeur de chaleur en spirale peut être fabriqué de façon aisée. Un élément de nettoyage en forme de corde, s'étendant le long d'un passage dans la direction longitudinale des plaques de transfert de chaleur en forme de bande, est actionné pour commuter l'entrée et la sortie d'un fluide, de telle sorte que l'élément de nettoyage en forme de corde peut être amené à coulisser librement, comme un élément d'essuyage long dans la direction axiale de la spirale, pour nettoyer ainsi les faces de transfert de chaleur des plaques de transfert de chaleur en forme de bande opposées. Les deux plaques de transfert de chaleur en forme de bande sont reliées à un cylindre à âme semi-cylindrique, dont un cylindre à âme centrale peut être assemblé et démonté, pour constituer des éléments d'unités mutuellement indépendants, de telle sorte que les plaques de transfert de chaleur en forme de bande peuvent être aisément fabriquées et nettoyées. Une plaque d'extrémité en forme de coupelle inversée et des nervures de renforcement peuvent être utilisées d'un seul tenant dans l'élément de recouvrement ou une bride fermée, de telle sorte que non seulement la bride fermée, mais encore l'échangeur de chaleur en spirale, peuvent avoir un poids réduit.
