Abstract
A heat-exchanger for fluids is designed with an outer cylindrical casing and, inside the same, a plurality of coaxial heat-exchange surfaces forming axial flow passageways for fluids therebetween, with two ends each bearing a connection-box for the fluid inlets and outlets. This connection-box is connected to the outer peripheral heat-exchange surface and includes partitions extending from the axis to the periphery and engaging the edges of the heat-exchange surfaces. Obturators join pairs of edges of successive heat-exchange surfaces whereby each end of the succession of heat-exchange surfaces offers annular passageway portions and annular obturated portions. The outer cylindrical casing is formed by a shell made of thick sheet metal withstanding the pressure forces and said heat-exchange surfaces are formed by thin metal sheets of insufficient strength in themselves but which are buttressed against one another through the agency of spacer means effective in transferring pressure forces to said outer cylindrical casing made of thick sheet metal.
