Zusammenfassung:	PCT No. PCT/SU90/00047 Sec. 371 Date Dec. 13, 1991 Sec. 102(e) Date Dec. 13, 1991 PCT Filed Feb. 20, 1990 PCT Pub. No. WO91/13309 PCT Pub. Date Sep. 5, 1991.A stack comprises plates (1,2,3,4) having a zig-zag profile and defining diverging-converging passages in the flow direction (L) of the first heat-exchange medium. Each plate (1,2,3,4) has in the direction (M) perpendicular to the flow direction (M) of the first medium several rows (10) of equally spaced openings (11) accommodating tubes (11a) for a flow of the second heat-exchange medium. Each plate (1,2,3,4) has an odd number of portions (12,13) whose zig-zag profile is offset with respect to the zig-zag profile of the adjoining portion by one half of the pitch (t) of the zig-zag pattern of the profile. The rotary die set for producing the plates of this stack comprises two die rolls (19,20). The length of the evolution of the shaping surface (21,22) of each roll (19,20) is divided into an even number of portions of the same length. The zig-zag profile of each portion is offset with respect to the zig-zag profiles of the adjoining portions through one half of the pitch of the zig-zag pattern of the profile. L'ensemble comprend des plaques (1, 2, 3, 4) présentant un profil en zigzag et formant, dans le sens (4) de l'écoulement du premier caloporteur, des canaux diffuseurs-convergents. Dans le sens (M) perpendiculaire au sens (L), chacune des plaques (1, 2, 3, 4) comporte plusieurs rangées (10) d'orifices (11) espacés à égale distance les uns des autres, dans lesquels sont insérés des tubes (11a) permettant le passage du second caloporteur. Chacune des plaques (1, 2, 3, 4) comporte un nombre impair de sections (12, 13), le profil en zigzag de chacune d'elles étant décalé par rapport au profil en zigzag de la section adjacente de la moitié du pas (t) du zigzag du profil. Une matrice de rotor permettant de fabriquer les plaques dudit ensemble comprend deux cylindres (19, 20). La longueur développée de la surface de formage (21, 22) de chacun des cylindres (19, 20) est divisée en un nombre pair de sections de longeur égale. Le profil en zigzag de chacune des sections est décalé par rapport aux sections en zigzag des sections adjacentes, de la moitié du pas du zigzag du profil.
