Heat exchange and/or chemical reactor apparatus (10; 100) comprises a series of plates which are stacked and bonded together in a fluid-tight manner, the series of plates comprising alternate first (30; 130) and second (90; 190) plates or groups of plates along the stack providing flow paths for respective first and second fluids, each plate forming said first (30; 130) and second (90; 190) plates or groups of plates having an inlet (42, 90) and an outlet (43, 91) between which respective first or second fluid is flowable and a continuous wall (34, 84) to contain the flow of fluid, and characterised in that each plate (30, 90; 130; 190) comprises an outer wall (43, 83) continuous wall (34, 84) to define a space (35, 85) therebetween, the spaces (35, 85) of each plate (30, 90; 130; 190) of the stack being in fluid communication to form a compartment running along the stack.

L'invention concerne un dispositif de type échangeur thermique et/ou réacteur chimique (10 ; 100) comprenant une série de plaques empilées et collées les unes aux autres de manière étanche. Cette série de plaques comprend des premières (30 ; 130) et secondes (90 ; 190) plaques ou des premiers et seconds groupes de plaques qui sont disposé(e)s de manière alternée le long de l'empilement et constituent des voies d'écoulement pour des premiers et seconds fluides respectifs. Chaque plaque desdites premières (30 ; 130) et secondes (90 ; 190) plaques ou desdits premiers et seconds groupes de plaques est pourvue d'une entrée (42, 90) et d'une sortie (43, 91) entre lesquelles un premier ou un second fluide respectif peut s'écouler, ainsi que d'une paroi continue (34, 84) qui sert à contenir l'écoulement de fluide. Cette invention est caractérisée en ce que chaque plaque (30, 90 ; 130, 190) comprend une paroi extérieure (43, 83) qui entoure au moins partiellement ladite paroi continue (34, 84), ce qui définit un espace (35, 85) entre lesdites parois. Les espaces (35, 85) des plaques (30, 90 ; 130, 190) de l'empilement sont en communication fluidique les uns avec les autres, ce qui forme un compartiment s'étendant le long dudit empilement.
