HEAT EXCHANGER Russian patent published in 2010 - IPC F28D7/00 

FIELD: heating systems.

SUBSTANCE: invention refers to heat exchange equipment and can be used in water treatment system of nuclear power plant. Heat exchange contains housing with heat exchange liquid inlet and outlet connection pipes, bank of V-shaped heat exchange tubes fixed in tube sheet comprising together with cover by means of a partition two chambers along the path of one of the liquids; at that, straight sections of V-shaped heat exchange tubes are put with a gap to the tubes the ends of which are rigidly fixed in separate tube sheets, and bent sections are placed in the cavity comprised with tube sheet and bottom; at that, this cavity is interconnected by means of tubular gaps with cavity and connection pipe to it, and isolated from paths of heat exchange liquids.

EFFECT: design with proposed layout of tube bank will allow obtaining small scale heat exchangers meeting the requirements of reliability, manufacturability, erection at high specific thermal stresses of the occupied volume of nuclear power plant.
