HEAT EXCHANGER WITH RIBBED TUBES Russian patent published in 2016 - IPC F28F13/12 F28F9/24 

FIELD: heat exchange.

SUBSTANCE: present invention relates to a heat exchanger with ribbed tubes comprising tubes, through the inner space of which a heat carrier flows and which are arranged in parallel at an equal distance between them so, that the combustion product can pass through the space between the tubes; and heat transfer ribs spaced apart relative to each other and connected to the outer tubes surface along their longitudinal direction in order to be located in parallel to the combustion product flow. Inside the tubes there is the first generating a turbulent flow element to create turbulence in the flow of the heat carrier. First generating the turbulent flow element comprises a flat plate part located in the longitudinal direction of the tubes for separation of tubes inner space into two spaces and the first guide elements and the second guide elements, which are spaced apart relative to each other and in turn extend inclined along the longitudinal direction on both sides of the flat plate part.

EFFECT: improved heat exchange efficiency by increasing the heat carrier flow turbulence.
