HEAT-EXCHANGE APPARATUS (VERSIONS) Russian patent published in 2009 - IPC F28D15/00 

FIELD: heating.

SUBSTANCE: in heat-exchange apparatus, which contains body with bottoms, branch pipes of input and output of heat carrier in pipe and inter-pipe space, pipe grids, in whose openings conic (according to version 1) pipes, partitions, novelty lies in the fact that apparatus body is made conic and widening towards pipe widening. Deviation angle of body generating line relative to central axle is greater than angles of deviation of pipe generating lines relative to their axles. In heat-exchange apparatus (version 2) body is made conic, and pipes are made cylindrical, located at angle to central body axle, inclinations of cylindrical pipes getting smaller towards central pipe. Angle of deviation of generating line of body surface from its central axle is greater than angle of deviation of cylindrical pipes axles from central body axle.

EFFECT: increase of heat-exchange intensity with low metal consumption.
