ARRANGEMENT OF HEAT EXCHANGER Russian patent published in 2016 - IPC F24H1/00 

FIELD: heat exchange.

SUBSTANCE: arrangement of heat exchanger, in particular, for heating device comprises:

inner housing (12) of heat exchanger in form of pot with first wall (16) of bottom and having attached to first wall (16) of bottom enclosing longitudinal axis (L) of first wall (18) by periphery; outer housing (14) of heat exchanger in form of pot with second wall (20) of bottom and having attached to second wall (20) of bottom enclosing longitudinal axis (L) of second wall (22) by periphery; flow space (24) of fluid medium formed between inner housing (12) of heat exchanger and outer housing (14) of heat exchanger; first guide flow structure (40) extending, in fact, in direction of longitudinal axis (L) along first wall (18) by periphery and second wall (22) by periphery, and second guide flow structure (42) extending, in fact, in direction of longitudinal axis (L) along first wall (18) by periphery and second wall (22) by periphery with gap along circumference to first guide flow structure (40), at that, first flow-guiding structure (40) and second flow-guiding structure (42) divide formed between first wall (18) by periphery and second wall (22) by periphery part (28) of fluid flow space (24) to first part (44) of flow space and second part (46) of flow space; at least one inlet (49) for fluid medium, open to first part (44) of flow space, and at least one outlet hole (51) for fluid medium, open to second part (46) of flow space; press fitting structure (94) to fix inner housing (12) of heat exchanger relative to outer housing (14) of heat exchanger, wherein press fit structure (94) includes first guide flow structure (40) and second guide flow structure (42) and/or press fitting structure (94) is provided in limit area (32) of walls (18, 22) by periphery located at a distance from first wall (16) of bottom and second wall (20) of bottom.

EFFECT: disclosed is design of heat exchanger for vehicle heating device.
