| 摘要 |
The present invention relates to a heat exchanger (50) comprising a plurality of plates (10, 20) provided with a planar peripheral area (19, 29), an internal area provided with sinusoidal undulations (13, 23, 14, 24) and two chimneys (11, 21, 12, 22) positioned at two opposing corners of said plates (10, 20). Modules (30) are formed by the assembly of two plates (10, 20) which are in engagement at the troughs (14, 24) of said undulations and at said peripheral areas (19, 29). The modules (30) are stacked such that the inlet (11, 21) and outlet (12, 22) chimneys are in engagement. Each module (30) may thus be deformed independently, in particular in the region of the troughs (14, 24) and peaks (13, 23) of said undulations, without transmitting stresses to the other modules (30) of said exchanger (50). In addition, said exchanger (50) may comprise a tie (40) in each inlet (53) and outlet (54) pipe in order to resist the static pressure of the fluids circulating in said pipes (53, 54). |
