trocador de calor de placas para reatores químicos isotérmicos

摘要

A radial-flow plate heat exchanger (5) embedded in the catalytic bed of an isothermal chemical reactor (1) has heat exchange plates (10) comprising fluid passages (13) between a first metal sheet (20) and a second metal sheet (21) joined by perimeter weld seams (23) on a first surface (A) of the plate; a feeding channel (14) and a collecting channel (15) for the heat exchange fluid are formed with suitable metal sheets which are seam welded (25) directly to the opposite surface (B) of the plate; this structure allows the manufacturing of the plate (10) with an automated seam welding process, such as laser beam welding.
