Abstract[English]
The invention relates to a tube-in-tube merger comprising a rigid outer casing (1) and an interior expanding substance (2) with a through hole. The through hole is arranged to receive merging tubes (3, 4), one merging tube (4) inside the other (3). The tube-in-tube merger through hole size at a lower assembly temperature is larger than the outer size of the merging tubes (3, 4), while at a higher merging temperature the tube-in-tube merger through hole size is equal to the outer size of the merging tubes (3, 4). The interior expanding substance (2) has a higher coefficient of thermal expansion than the rigid outer casing (1), causing the size of the through hole to contract at an elevated temperature. By elevating the temperature to a merging temperature, the tube-in-tube merger grasps the merging tubes (3, 4) and melts at least one of them, permanently joining them.[French]
La présente invention concerne un dispositif de fusion tube-dans-tube comprenant un boîtier extérieur rigide (1) et une substance expansible intérieure (2) pourvue d'un trou traversant. Le trou traversant est disposé pour recevoir des tubes fusionnant (3, 4), un tube (4) fusionnant à l'intérieur de l'autre (3). La taille du trou traversant du dispositif de fusion tube-dans-tube à une température d'assemblage basse est supérieure à la taille externe des tubes fusionnant (3, 4), tandis qu'à une température de fusion plus élevée, la taille du trou traversant du dispositif de fusion tube-dans-tube est égale à la taille extérieure des tubes fusionnant (3, 4). La substance expansive intérieure (2) présente un coefficient de dilatation thermique supérieur à celui du boîtier externe rigide (1), ce qui provoque une contraction de la taille du trou traversant à une température élevée. Par élévation de la température jusqu'à une température de fusion, le dispositif de fusion tube-dans-tube saisit les tubes fusionnant (3, 4) et fait fondre au moins l'un d'eux, les reliant de manière permanente.
