HEAT EXCHANGER WITH INTERMEDIATE FLUID
A heat exchanger (preferably for nuclear reactors) comprises a first space in which the heating fluid circulates, a second space traversed by the cold fluid, and a third space formed by the walls bounding the said first and second spaces, respectively. This third space is filled by a thermally conductive liquid that is immiscible with the other fluids. Preferably, the first space is constituted by the inside of the inner tubes of a plurality of parallelly arranged double-walled tubes connected at their ends by headers. The second space is that between the containing shell and the outer of the double-walled tubes. The thermally conducting liquid is filled into the annular interspaces of the doub1e-walled tubes. This last 1iquid is held at a lower pressure than the other fluids. (NPO)
