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

FIELD: heat exchange 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. Shells have different diameters, increasing from inlet part to central part and decreasing from central part to outlet part. Number of shells of inlet part corresponds to number of shells of outlet part. Shells 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: technical result is improvement of technical characteristics and expansion of functional capabilities of heat exchanger.
