HEAT EXCHANGER Russian patent published in 2019 - IPC F28D7/10 

FIELD: heating equipment.

SUBSTANCE: invention relates to heat exchange technology and can be used to create heat exchangers. Heat exchanging device housing consists of inlet, central and outlet parts. Central part is made in the form of a hollow cylinder with two bottoms, and inlet and outlet parts are made of several hollow cylindrical shell rings attached to each other. Shell rings have different diameters, increasing from inlet part to central part and decreasing from central part to outlet part. Number of shell rings of inlet part corresponds to number of shell rings of outlet part. Shell rings are installed in series on both sides of central part of housing so that alternating cavities of first and second components are formed. Heat exchange elements are made in the form of several coaxially installed pipes of different diameter and different length. Pipes of larger diameter and smaller length form peripheral part of heat exchange element, and pipes of smaller diameter and longer length form its central part.

EFFECT: heat exchanger is proposed.
