The invention provides an improved heat exchanger and/or fluid mixing means which comprises a bonded stack of plates, the stack comprising at least one group of main perforated plates, wherein at least two adjacent plates of the group of main perforated plates have their perforations aligned in rows with continuous ribs between adjacent rows, and the adjacent plates are aligned whereby the rows of perforations in one plate overlap in the direction of the rows with the rows of perforations of an adjacent plate and the ribs of adjacent plates lie in correspondence with each other to provide discrete fluid channels extending across the plates, a channel corresponding to each row of perforations, the channels together forming one or more fluid passageways across the plates and the passageway(s) in the group of main perforated plates being separated from passageway(s) in any adjacent group of perforated plates by an intervening plate.

Heat exchanger and/or fluid mixing means

The invention provides an improved heat exchanger and/or fluid mixing means which comprises a bonded stack of plates, the stack comprising at least one group of main perforated plates ( , P, R), wherein at least two adjacent plates (P, R) of the group of main perforated plates have their perforations ( ) aligned in rows with continuous ribs ( ) between adjacent rows, and the adjacent plates (P, R) are aligned whereby the rows of perforations ( ) in one plate (P) overlap in the direction of the rows with the rows of perforations ( ) of an adjacent plate (R) and the ribs ( ) of adjacent plates lie in correspondence with each other to provide discrete fluid channels ( ) extending across the plates, a channel ( ) corresponding to each row of perforations ( ), the channels together forming one or more fluid passageways ( ) across the plates and the passageway(s) ( ) in the group of main perforated plates being separated from passageway(s) ( ) in any adjacent group of perforated plates by an intervening plate (TS).
