Abstract (en)

[origin: WO2008108724A2] The invention relates to a heat exchanger (1) of crossflow type for heat exchange between different media, which heat exchanger (1) comprises a plate stack (2) of heat transfer plates for first and second plate types (3, 4). The plate types (3,4) are stacked 5 alternately on one another in the plate stack (2). Each plate type (3, 4) has a side A and a side B with a heat exchange surface (9). The heat exchange surface (9) comprises a pattern (10a, b). In the plate stack (2), adjacent plate types (3, 4) form both first throughflow ducts (14) and second throughflow ducts (15). Said first throughflow ducts (14) have a larger volume than said second throughflow ducts (15), the volume of a first medium (16) in said 10 first throughflow ducts (14) beinggreater than the volume of a second medium (17) in said second throughflow ducts (15). Said media (16, 17) are subject to heat transfer between them through the heat exchange surface (9) between the ducts (14, 15), the pressure drop of medium (16) flowing through the first throughflow duct (14) being less than the pressure drop of medium (17) flowing through the second throughflow duct (15).
