HEAT EXCHANGER Russian patent published in 2009 - IPC F22D1/32 

FIELD: power engineering.

SUBSTANCE: in cavity of body 1 there are longitudinally installed tubular screens. Each screen has internal branch 7 and external branch 8. Internal branch 7 is installed between external branch 8 and displacer 9, attached to central header 4, and external branch 8 is arranged as extension of internal branch 7 and is located near wall of body 1. In each screen internal and external branches 7 and 8 are arranged along length from rotary sections 10 and 11, being placed with alternation by one from the side of wall of body 1 and displacer 9. Rotary sections 10 of internal branch 7, located on side of body wall 1, are installed inside analog rotary sections 10 of external branch 8. Rotary sections 11 of external branch 8, located at displacer side 9, are installed inside analog rotary sections 11 of internal branch 7. Such design of heat exchanger makes it possible to organise transverse streamline of screen pipes with coolant and to intensify heat exchanger in tube space.

EFFECT: reduced required surface of heat exchange, body dimensions and reduced metal intensity of heat exchanger.
