Heat exchanger of stacked plates. (Machine-translation by Google Translate, not legally binding)

Plate heat exchanger stacked. Heat exchanger (1) of stacked plates, comprising a plurality of stacked plates (2) between which circulate the fluid to be cooled and the refrigerant fluid between two independent circuits defined by said plates (2), in alternating layers, a housing (4) provided to house in its interior the set of plates (2), and fastening means (5, 6) of the set of plates (2) to the ends of the casing (4), said fastening means (5) being, 6) susceptible to be fixed by welding in the oven. It is characterized in that said fastening means comprise a plurality of tabs (5, 6) located at the ends of the casing (4) and mechanically adjustable to the free ends of the set of plates (2), so that tabs (5, 6) are capable of substantially covering the existing holes in said joining areas between the set of plates (2) and the casing (4). A new configuration with a robust and safe design of the parts to be assembled by welding in the oven is obtained.

Intercambiador de calor (1) de placas apiladas, que comprende una pluralidad de placas apiladas (2) entre las cuales circulan el fluido a refrigerar y el fluido refrigerante entre dos circuitos independientes definidos por dichas placas (2), en capas alternadas, una carcasa (4) prevista para alojar en su interior el conjunto de placas (2), y medios de sujeción (5, 6) del conjunto de placas (2) a los extremos de la carcasa (4), siendo dichos medios de sujeción (5, 6) susceptibles de ser fijados mediante soldadura en horno. Se caracteriza por el hecho de que dichos medios de sujeción comprenden una pluralidad de lengüetas (5, 6) situadas en los extremos de la carcasa (4) y ajustables mecánicamente a los extremos libres del conjunto de placas (2), de modo que dichas lengüetas (5, 6) son susceptibles de recubrir sensiblemente los orificios existentes en dichas zonas de unión entre el conjunto de placas (2) y la carcasa (4). Se obtiene una nueva configuración con un diseño robusto y seguro de las partes a ensamblar mediante soldadura en horno.
