The Termo-Fluido-Dinamic Performance<\/h2>\n

One of the main problems on Air Fin Coolers is the Header bending<\/strong>, caused\u00a0by the tightening of the bolts on the flange Headers.<\/span><\/p>\n

Because of that, the thermo-fluid-dynamic efficiency<\/strong> of the equipment is compromised<\/strong>.\u00a0In fact this bending header deformation allows, erroneous, the fluid to pass though header groove and not inner finned tubes (see picture), finally not being cooled for\u00a0the process.<\/span><\/p>\n

 <\/p>\n

\"\"<\/strong><\/p>\n

Furthermore this fluid passage could start erosion phenomena damaging<\/strong>\u00a0pass-rib and header, increasing the quantity of fluid moving in the other wrong area\u00a0of the equipment.<\/span><\/p>\n

Another risk is the mass flow rate loss inside finned tubes<\/strong>, with\u00a0consequently increasing drop pressure caused by inner dirtiness lay down.\u00a0More over, if bolts load is limited to avoid the Header bending, then could happen to\u00a0have not the correct pressure along the gasket seat with consequent fluid leaks.<\/span><\/span><\/p>\n

\n

VED\u2019s Research&Development Division found the solution to the above issues by\u00a0using a special gasket that assure the sealing at low loads in order to not\u00a0incur into Header deformation bending.<\/span><\/h2>\n<\/blockquote>\n

By Cutting from a sheets layer, this gaskets\u00a0are made in sectors<\/strong>, with puzzle junctions<\/span>; easy to handle, all the complete long\u00a0gasket will be mounted directly on the flange seat<\/strong>, jointing all the pieces between\u00a0themselves.<\/span><\/p>\n
