<p>1. Bracing structure for the tubular bundle of a heat exchanger for maintaining the transverse position of the tubes (11) whilst allowing longitudinal circulation of the fluid which contacts the outer surface of the tubes, characterised by the fact that it comprises a flat metal sheet (1) each face of which includes a series of parallel grooves (2, 3) having different directions for each face, the depths of said grooves (2, 3) respectively, relative to each face being such that their sum is greater than the thickness of said sheet (1), the number, spacing and width of the said grooves (2, 3) being determined as a function of the corresponding characteristics of the tubular bundle.</p> |
