HELICAL TUBE BUNDLE ARRANGEMENTS FOR HEAT EXCHANGERS

A heat exchanger comprising helically wound tube bundles is disclosed. The helically wound tube bundles are joined with tube sheets to define a primary working fluid system that is fluidically isolated from a secondary working fluid system. The tube sheets and tubes are formed of the same material,...

Zusammenfassung:A heat exchanger comprising helically wound tube bundles is disclosed. The helically wound tube bundles are joined with tube sheets to define a primary working fluid system that is fluidically isolated from a secondary working fluid system. The tube sheets and tubes are formed of the same material, which facilitates their joining by means of joints that are substantially galvanic corrosion-resistant joints. L'invention porte sur un échangeur de chaleur, qui comprend des faisceaux de tubes enroulés de façon hélicoïdale. Les faisceaux de tubes enroulés de façon hélicoïdale sont assemblés avec des feuilles de tube afin de définir un système de fluide de travail primaire qui est isolé vis-à-vis des fluides d'un système de fluide de travail secondaire. Les feuilles de tube et les tubes sont formés à l'aide du même matériau, ce qui facilite leur assemblage à l'aide de raccords qui sont des raccords résistant à la corrosion essentiellement galvanique.
