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 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 shell rings located in relation 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 ring of the hot component supply belt, on the other side – with the shell ring of the cold component supply belt. End faces of the shell rings on the side of the inlet are provided with end profiled bottoms fixed to each other and to the housing and forming in-series end annular 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: present invention improves technical characteristics of the heat exchanger and broadens its functional capabilities.
