Abstract (en)
The subject of the invention is a group of plates (1) for a heat-exchanger, of the type comprising a stack of plates (20 - 30) which are parallel to each other, each plate (20 - 30) including edges (21 - 31; 22 - 32) with a smooth surface, and a central part (23 - 33) which is corrugated to form with the associated plates a double circuit for circulating two independent fluids in counterflow, the said group being composed of a multitude of elements which are superposed and are each formed by a pair (A) of plates (20 - 30) assembled together. The plates (20 - 30) of each pair (A) are assembled together by means (10) for linking the superposed elements which are connected together by a continuous or discontinuous longitudinal weld bead (14). A further subject of the invention is a method of assembly and a heat-exchanger provided with such a group of plates. <IMAGE>
