HONEYCOMB HEAT EXCHANGER WITH FLOW SWIRLING Russian patent published in 2010 - IPC F28F1/00 

FIELD: heating.

SUBSTANCE: in honeycomb heat exchanger with flow swirling, which includes tube bundle of heat exchange tubes having ends made in the form of equilateral polygons adjacent to each other and connected to each other along the edges, the ends of each tube are made in the form of hexagon; one or more tubes tightly connected to each other and without any gaps are made so that a module is formed, and tube bundle is composed of one module or several tight modules connected to each other and is fixed with shells on the ends; at that, as heat exchange tubes there can be used spiral-shaped tubes made with equal or various spiral ascending angles; at that, side surface of each tube consists of one or several zones, each of which has its own geometrical shape, number of entries and spiral ascending angle.

EFFECT: reducing production costs, improving operating reliability and decreasing operating costs.
