CONDENSER HEAT EXCHANGE ELEMENT Russian patent published in 1997 - IPC

FIELD: structural members of condensers of refrigerating machines. SUBSTANCE: heat exchanger element includes two plates 1 and 2 oriented vertically and mounted opposite each other forming tight slotted passage; plates are provided with steam inlet hole 4 and condensate outlet hole 5. Heat exchange element is also provided with wheel arranged in passage; this wheel has radial blades 6 mounted for rotation on horizontal axle 7 secured to plates; side edges of blade adjoin surface of plate. Heat exchange element is also provided with guide branch pipe connected with steam inlet hole this branch pipe has outlet section directed towards blades whose axis is parallel to plates. Guide branch pipe is oriented tangentially to tip edges of blades which may be bent backward; they nay be made from flexible material. Capillary porous structure may be placed in slotted passage over periphery of wheel which adjoins plates, thus excluding return of condensate film to surface of plate under action of gravitational force. EFFECT: enhanced efficiency. 10 cl, 4 dwg
