RADIAL-TUBE HEAT-MASS-EXCHANGE APPARATUS Russian patent published in 2017 - IPC F28D9/04 

FIELD: heating system.

SUBSTANCE: heat-mass-exchange apparatus includes a housing with fluid inlet/outlet connections in which one or more adjacent units are installed consisting of vertical heat-mass-exchange elements in contact by turbulent projections forming an annular series around the vertical axis of the housing, forming the peripheral and central distribution manifolds in which the partitions are placed that provide a turn of the radial flow of fluid during the transition between units. The walls of the heat-mass-exchange elements are connected by one horizontal weld joint located on the lateral surface or in the rear part, wherein the front and back parts of the heat-mass-exchange element have an elliptical shape in cross section. When the heat-mass-exchange apparatus is operated, the flow of one fluid passes in the axial direction, flowing heat-mass-exchange elements, the front and/or rear parts of which have a close to perfect hydrodynamic shape. The flow of the other fluid flows around the heat-mass-exchange elements in a radial direction, first from the periphery to the center, and then back.

EFFECT: lowering the hydraulic resistance and increasing the reliability of the apparatus.
