Heat exchanger for exchanging heat between two fluids, use of the heat exchanger with liquid metal and gas and use in a fast neutron reactor cooled by liquid metal

摘要

Use of heat exchangers to exchange heat between two fluids, exchangers with liquid metal and gas, and use in liquid metal cooled fast neutron reactors. The present invention relates to a heat exchanger (1) for exchanging heat between a first fluid (N2) and a second fluid (Na). According to the invention, the structure of the heat exchanger is to a predetermined longitudinal end (2a) opposite the longitudinal end (2b) from which the secondary fluid, for example nitrogen (N2) is supplied and recovered, and Makes it possible to supply and recover a primary fluid, for example sodium (Na). This is particularly true in an exchanger that allows restricted access for one of the fluids, for example sodium (Na), and unrestricted access for the other, for example nitrogen (N2). Provides physical separation between the two fluid paths.
