Abstract

L'invention concerne un fil de chauffage électrique composite qui suit un tuyau en matière plastique chauffé et isolé thermiquement, capable d'utiliser une énergie électrique minimale pour chauffer électriquement, rapidement et en toute sécurité, la paroi intérieure du tuyau pour réaliser un dégivrage rapide et uniforme, formant ainsi un conduit d'écoulement de liquide et permettant à l'eau chaude dans le tuyau de s'écouler en aval à travers tout le tuyau afin de réaliser un dégivrage rapide. La puissance d'une alimentation à basse tension peut être commandée par un élément de commande, la chaleur générée par un conducteur peut empêcher le tuyau isolé thermiquement de geler, et l'eau dans le tuyau peut être maintenue à une certaine température par commande de l'alimentation, ce qui confère une fonction d'alimentation instantanée en eau chaude lors de l'ouverture d'un robinet. On dispose ainsi d'un processus de production simple et fiable qui augmente considérablement la résistance du tuyau car le phénomène de surchauffe du système de chauffage électrique est largement évité grâce à la présence d'eau dans le tuyau, qui met en œuvre une tension réglable par réglage de la tension et qui s'inscrit dans la démarche de développements futurs de tuyaux isolés thermiquement.
