HEAT EXCHANGER IN COMPOSITE MATERIAL AND METHOD FOR MAKING SAME

摘要

The invention concerns a heat exchanger comprising an intermediate part (14) made of refractory composite material, for instance of C/C composite, wherein are formed ducts for fluid (16) circulation, and which is interposed between a part made of refractory composite material, for instance with a ceramic matrix, such as a C/SiC composite, forming a thermal screen (12) and a part made of thermostructural composite material, for instance a C/C composite, forming a structure maintaining the exchanger (18), the components of the exchanger being assembled by brazing. The heat exchanger is useful as wall element exposed to an intense heat flow particularly in a nuclear fusion reactor and a ramjet combustion chamber.
