HEAT EXCHANGING DEVICE (OPTIONS) Russian patent published in 2018 - IPC F28D7/04 

FIELD: heat exchange.

SUBSTANCE: invention relates to the design of apparatuses for heat exchange between fluid streams and can be used in various industries. Apparatus is proposed consisting of a housing with fluid inlet/outlet nozzles in which a heat exchange unit with sections connected by inner and outer bushes is coaxially mounted, at least one of which is made in the form of a bellows to compensate for axial temperature deformations of the apparatus elements equipped with rings and covers, two of which are connected by pipelines to the branch pipes of introducing one of the fluids. When the apparatus is operating, the first fluid through the first branch pipe and the first cover is first directed into one of the cavities of the sections of the heat exchange unit from which the fluid is withdrawn through the second cover and the second branch pipe. Second fluid passes through the third branch pipe to the adjacent cavity of the sections of the heat exchange unit, from which the fluid is withdrawn through the fourth branch pipe.

EFFECT: increasing the reliability of the device.
