ABSTRACT:
A heat pipe type heat exchanger, such as a steam generator for use in combination with a fast breeder reactor, comprises two double walls consisting of an outer wall and an inner wall and of an outer wall and an inner wall, respectively, and a plurality of double tubes each consisting of an inner tube and an outer tube coaxially receiving the inner tube therethrough. A heating fluid flows through spaces between the outer tubes and the inner walls of the double walls, while a heated fluid flows through the inner tubes. A heat transfer medium is contained in evaporating spaces each defined by the inner surface of the outer tube and the outer surface of the inner tube. The heat transfer medium is evaporated by the heat of the heating fluid, condenses over the surfaces of the inner tubes to transfer heat to the heated fluid flowing through the inner tubes. Each evaporating space is partitioned into many sections by baffle plates to enhance the heat flux in the evaporating space. The evaporating spaces are connected to manifold plenums and the manifold plenums are connected to damage detecting systems and heat transfer medium maintenance systems.
