HEAT EXCHANGER Russian patent published in 2010 - IPC F28D7/08 

FIELD: heating systems.

SUBSTANCE: invention refers to heat engineering and can be used during arrangement of high thermally stressed heat exchanger of nuclear power plant. In heat exchanger consisting of bank of heat exchange coil tubes the ends of which are fixed in tube sheets arranged in the form of a platen, straight sections of several coil tubes are located consequently in one plane, and bent sections are opened to the side from location plane of straight sections; at that, opening of bends of opposite ends, straight sections, is made to different sides.

EFFECT: providing maximum compactness of tube bank of heat exchanger and reaching high degree of heat exchange efficiency owing to arrangement of heat removal surface itself during operation, increasing life time of reliable operation of heat exchanger design at high specific thermal stresses of the volume occupied with it.
