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

FIELD: heat exchange.

SUBSTANCE: invention relates to heat exchange technology and can be used to create heat exchangers. Heat exchanger comprises housing with inlet and outlet branch pipes for inlet and outlet of hot and cold components, belt for supply of hot and cold components, connected to corresponding cavities of components by means of channels. Belts of hot and cold components supply are made in the form of several coaxially installed shells located each relative to each other with annular gaps, and forming closed annular cavities. In the central part of the housing, between the components feeding belts, there is a belt for supply of the additional component, on one side interacting with the shell of the hot component supply belt, on the other side – with the shell of the cold component supply belt. End faces of the shell shells on the side of the inlet are provided with profiled end bottoms fixed to each other and to the housing and forming in-series annular end cavities. In the above bottoms and cavities there are isolated channels connecting said end cavities of supply of hot and cold components through one to each other, wherein said annular cavities of components are connected to corresponding cavities of supply of components through said end cavities formed by profiled bottoms.

EFFECT: improved technical characteristics and expansion of heat exchanger functional capabilities.
