Device for fixing a panel of heat-exchange tubes

A device for fixing a panel of horizontal or slightly inclined heat exchange tubes on vertical tubes or beams provided with longitudinal fins, wherein the device includes:

• means defining a series of vertically spaced horizontal shoulders on the longitudinal fins of each vertical tube or beam, said shoulders having upwardly projecting rims at their ends remote from said vertical tubes or beams;
• a series of parts which form latches having upper surfaces which are substantially flat on one side and which rise on the other side in a circle with a radius of curvature equal to or slightly greater than that of the radius of said horizontal tubes, the parts which form latches having, under the substantially flat sides of their upper surfaces middle portions, noses which are separated from said middle portions by recessed portions, said recessed portions fitting into the projecting rims of the shoulders, vertical shoes in planes at 90.degree. to the planes of vertical symmetry of said parts, said shoes being of nearly the same vertical height as the rims of the shoulders and having in their bottoms holes whose axes are perpendicular to their longitudinal axes;
• and
• a series of dogs whose dimensions are such as to allow them to be installed in said holes of the parts which form latches and being positioned therein, each dog having downwardly projecting legs whose height is such that their ends come into contact with the upper portion of a horizontal tube which rests on the upper surface of the part which forms a latch immediately below when inserted in said holes, and a side rim in its upper portion such that when urged upwards, the dog abuts against the lower surface of the shoulder on which the part which forms a latch is fixed with the dog engaged in a hole in the shoulder.
