Abstract
A ceramic unit for indirect heat exchange, said unit being formed by extruding raw ceramic material in a parallel duct configuration, piercing a first series of inlet and outlet orifices for a fluid at the ends of a first series of ducts, the axes of said orifices being perpendicular to those of the ducts, and firing the unit. The inlet orifices (5) and/or the outlet orifices (9) are formed by making oblique cuts (7,10) on the ends of the rows of ducts to provide inlet or outlet openings perpendicular to the common direction of the ducts and then closing off the ends of the obliquely cut rows. Application to heat exchangers for turbine engines.
