FIELD: heating. ^ SUBSTANCE: invention refers to power industry and can be used in regeneration systems of nuclear power stations turbine plants. Heat exchanger includes the channel in which heat exchange tubular platens are installed. Each platen is made at least of two transverse sections and one turning section. Transverse sections of platen are installed one above the other so that a cavity is formed. Turning section of platen has internal tubes and external tubes located on the side of cavity and wall of channel respectively. Internal and external tubes are equipped with spacer bars located on both sides from them. Both spacer bars in the zones between external tubes and at least one spacer bar in the zones between internal tubes are provided with spacer corrugations. Spacer bars in the zones between external tubes are attached to each other by tightening elements which are located in corrugations of spacer bars. ^ EFFECT: design of heat exchanger ensures uniform washing speed of tubular platens, which leads to decreased vibrations and intense heat exchange. ^ 2 cl, 3 dwg |
