<p>Heat exchange assembly and relative process and production plant, of the type in which it is used: a plate evaporator (1), with evaporation duct (1'-1''-1''') obtained between two metallic metal-sheets welded one with the other, that with an outward duct (A) and a return duct (R) debouches into a mouth collector coupling sleeve(12) in a corresponding junction area (13'); a freezing circuit coaxial tubular system (3,4,5), having an external return tube (3) and an internal delivery capillary tubule (5), in which said capillary tubule (5) protrudes over said return tube end (3), where said tubular system is mouthed within said mouth collector coupling sleeve (12) of the evaporator (1), while said capillary tubule (5) debouches freely and is there clamped (11) within said delivery duct branch (1') of said evaporator (1) obtruding the non-return external passage, having the characteristic of avoiding the traditional welding operation allowing a substantially automatized production. <IMAGE></p> |
