A HEAT EXCHANGER PLATE MODULE, A PLATE HEAT EXCHANGER AND A PROCESS FOR THE PRODUCTION OF THE PLATE HEAT EXCHANGER

The present disclosure relates to a heat exchanger plate module (200) comprising a pressed heat exchanger plate (201) and a flat plate (201'), and a heat exchanger (1) comprising a plurality of the modules (200). The plates in the module comprise a first longitudinal end portion (101) comprising at least one fluid port (110), a second longitudinal end portion (102) comprising at least one fluid port (120) and an intermediate heat exchange portion (103) arranged in between the first and second longitudinal end portions. The pressed heat exchanger plate (201) further comprises a pressed corrugated pattern (P) with alternating tops and bottoms in the thickness direction (d) of the plate. The pressed pattern (P) comprises in the first and/or second longitudinal end portions (101; 102), a first fluid channel pattern (FCP1) leading fluid flow into the at least one fluid port (110; 130) and/or a second fluid channel pattern (FCP2) bypassing the at least one fluid port (120; 140). In the intermediate heat exchange portion (103), a third fluid channel pattern (FCP3) is in fluid communication with the first fluid channel pattern (FCP1) and/or a second fluid channel pattern (FCP2) and comprises a plurality of longitudinally extending wave-shaped pressed lines (1030) configured to form discrete fluid channels (31) in the longitudinal direction (I) of the heat exchanger plate module (200), when the pressed heat exchanger plate (201) is attached to the flat plate (201'). A compact heat exchanger structure can be provided.
