SCREW HEAT EXCHANGER Russian patent published in 2011 - IPC F28D1/04 F28F9/22 

FIELD: heating.

SUBSTANCE: screw heat exchanger containing tube sheets, heat exchange tubes removable from both sides of the cover includes tube banks of staggered arrangement for the first heat carrier, which are located diametrically in circumferential direction around central tube supplying this heat carrier and screw plate directing the movement of the second heat carrier transversely to those tubes.

EFFECT: design of heat exchanger with higher heat transfer coefficient of heat carrier, which is achieved by direction of its movement at an appropriate angle to tubes with other heat carrier and thus reducing specific consumption of materials of heat exchanger.
