Matsushita, Hitoshi Nakayama, Wataru Yanagida, Takehiko Kudo, Akio. Shell-side single-phase flows and heat transfer in shell-and-tube heat exchangers, 4 ![]() Some nuclear reactor constructions incorporating such an arrangement are described, including liquid metal reactors. The inner wall of the tubular baffle may have flexible expansible region. Some protection against thermal shock can be effected by arranging that the secondary heat exchange fluid is on the tube side, and by providing a thermal baffle to prevent direct impingement of hot primary fluid on to the cylindrical tube plates. Cylindrical tube plates are believed to be superior for carrying pressure loads and resisting the effects of thermal shock. The baffle is easily removable and can be withdrawn to enable insertion of equipment for inspecting the wall of the tube and tube attachments and to facilitate plugging of defective tubes. These ducts are interconnected at the closed end of the tube by the heat exchange tubes and the baffle comprises inner and outer spaced walls with the interspace containing Ar. Within this tube there is a tubular baffle that slidably seals against the wall of the tube between the cylindrical tube plates to define two co-axial flow ducts. In the arrangement described a longitudinally extending central tube is provided incorporating axially spaced cylindrical tube plates to which the opposite ends of the tubes are attached. Where the heat exchangers are immersed in a coolant such as liquid Na such inspection is difficult. The tubes are usually end supported by the tube plates that separate the two fluids, and in use the tube attachments to the tube plates and the tube plates can be subject to severe stress by thermal shock and frequent inspection and servicing are required. Tube-in-shell heat exchangers normally comprise a bundle of parallel tubes within a shell container, with a fluid arranged to flow through the tubes in heat exchange with a second fluid flowing through the shell.
