FIELD: heating. ^ SUBSTANCE: invention refers to heat engineering and can be used as heat exchange intensification device in heat exchange tube bundle of heat exchanger of nuclear power plant. In intensifier containing two rims with coaxial holes for heat exchange tube and connected to each other with cylindrical shell of larger diametre so that transient projection is formed between each rim and cylindrical shell, on cylindrical shell surface, along axis of the holes of each rim there made in helical line are the openings, and the beginning of each opening covers the surface of transient projection. ^ EFFECT: design of intensifier of the proposed type provides the possibility of serving as the spacer device and vortex generator for increasing heat exchange of liquids flowing as per a certain hydraulic scheme. ^ 1 dwg |
