Abstract
This heat exchange block (1) comprises a body (10), longitudinal channels (20) intended to the flow of a process fluid, and transverse channels (60), intended to the flow of a service fluid. According to the invention at least one front face (2), in particular upstream front face delimits a central bowl (3) defining a central surface (S3), a peripheral seat (4) defining a peripheral reference surface (S4) and a transition portion (5), the distance (h4) between peripheral surface (S4) and closest transverse channel (60a) being substantially superior to distance (h3) between central surface (S3) and closest transverse channel (60a). The thermal stress generated on the block of the invention is far lower than in prior art, so that lifetime of both block and heat exchanger is much longer than in prior art.
