CYLINDRICAL PLATE HEAT EXCHANGER Russian patent published in 2009 - IPC F28D9/00 F28F3/00 

FIELD: heating.

SUBSTANCE: invention relates to heat-process engineering and is to be utilised in any technology branch for reheating or cooling liquid or gaseous media. The cylindrical plate heat exchanger contains a heat exchange matrix of corrugated plates with shrink flangings and manifold flangings. Each plate is circular in shape; in its central part there are corrugations arranged as well as a throughhole for the manifold of one of the heat transfer media (for example, the greater density heat transfer medium) while in the other parts (segments) there are flanged throughholes arranged for the other heat transfer medium (that of lesser density). The corrugated plate section has additional outward flanging with each matching outward flanging weld (solder) connected and providing for leak-proof closure of the greater density heat transfer medium and the lesser density heat transfer medium ducts. The heat exchange matrix is confined in a hermetically sealed housing equipped with a sensor for control over heat transfer media leakage. Proposed are different versions of the plate central part design.

EFFECT: enhanced efficiency and reliability of the heat exchanger.
