Abstract
A two-media laminated jet impingement heat exchanger comprising a heat exchanger core (1) including a plurality of soild heat exchanger or spacer plates (7) and a plurality of corrugated heat exchanger plates (8, 9) respectively interposed between and secured to the adjacent solid heat exchanger plates (7) so as to define between adjacent heat exchanger plates (7) second channels for respectively accommodating the two media. Each of the corrugated heat exchanger plates (8, 9) include a plurality of surface portions (8a, 9a) extending substantially parallel to one another. At least two rows of orifices (10) are provided in the surface portions of the corrugated heat exchanger plates (8) associated with one medium for enabling a flow of the one medium therethrough. At least one row of orifices (11) is provided in the surface portion of the heat exchanger plates (9) associated with the other medium of the two media for enabling a flow of the other media therethrough. The at least two rows of orifices (10) in the surface portions (8 a) of the corrugated heat exchanger plates (8) are offset with respect to the corresponding rows in adjacent surface portions such that the one medium flows through the orifices and impinges on adjacent surface portions so as to define a tortuous flow path for the one medium through the respective channels associated with the one medium of the heat exchanger core (1).
