PROFILE OF PIPELINE FOR HEAT EXCHANGERS, HEAT EXCHANGER FOR CONDENSING BOILERS COMPRISING SAID PROFILE AND CONDENSING BOILER CONTAINING SAID HEAT EXCHANGER Russian patent published in 2019 - IPC F24H1/43 F28F1/02 

FIELD: heating equipment.

SUBSTANCE: invention relates to heat engineering and can be used in production of pipeline profile for production of heat exchanger (10) for condensing boiler (20), characterized in that cross-section of profile (1) has trapezoidal section (2) having two bases (4, 5) and two lateral sides (6, 7), and triangular section (3) having base (6) and two side sides (8, 9), wherein first lateral side (6) of trapezoidal section (2) coincides with base (6) of triangular section (3), and second lateral side (7) and bases (4, 5) of trapezoidal section and lateral sides (8, 9) of triangular section (3) form inner walls of profile (1), wherein first angle (α) formed between first base (4) of trapezoidal portion (2) and adjacent first lateral side (8) of triangular portion (3) is from 45° up to 135°, preferably 90°, and second angle (β) formed between second base (5) of trapezoidal portion (2) and adjoining second lateral side (9) of triangular portion (3) is from 180° up to 270°, preferably 225°. Besides, present invention relates to coil heat exchanger (10) for condensing boilers, which contains said profile (1), and to condensing boiler (20) containing said heat exchanger (10).

EFFECT: technical result is a wider range of technical equipment.
