摘要

Process and tool for mounting a capillary line on a plate of the evaporator and evaporator plate thus produced.The present invention relates to a tool for expansion for the assembly of a capillary line (7) in a plate of the evaporator (1),This tool which comprises a spindle (12), and an internal external mandrel (11) which is guided in a displaceable in the channel (13) of the internal mandrel (12).During the assembly of the capillary line (7) in a plate of the evaporator (1), the internal mandrel (12) is guided to a section (2) of a connecting line of the plate of the evaporator (1),And the outer mandrel (11) is guided through the channel (13) of the internal mandrel (12) inside a capillary channel (6) of the plate of the evaporator (1), to expand the same.Both spindles (11, 12) are flat on one side to distribute the pressure acting on one of the two sheets of plate evaporator during the expansion of the same.As widely as possible on the surface of the plate mentioned, thus avoiding any deformation of the plate mentioned.The capillary line (7) is guided within the capillary channel (6) and the expanded capillary channel (6) is printed with the capillary line (7) is guided inside her.
