Abstract RU 2705164 C1

FIELD: heating equipment.

SUBSTANCE: invention relates to heat exchange technology and can be used to create heat exchangers. Heat exchanger includes housing with inlet and outlet branch pipes for inlet and outlet of hot and cold flows, heat exchange elements made in the form of several coaxially installed shell rings located each relative to each other with annular gaps, which form annular cavities. Annular cavities of hot and cold flows regularly alternate. On end faces of shell rings there are end profiled bottoms fixed to each other and to the housing and forming in-series arranged annular cavities. Said bottoms have isolated channels connecting said end cavities through one another. Said annular cavities of heat exchange elements are connected to cavities of inlet and outlet branch pipes of cold and hot flows through the above end cavities formed with profiled bottoms.

EFFECT: present invention improves technical characteristics of the heat exchanger and broadens its functional capabilities.
