PLATE HEAT EXCHANGER Russian patent published in 2002 - IPC

FIELD: heat power engineering. SUBSTANCE: plate heat exchanger has stamped plates in the form of ball-shaped lugs and cavities and flat plates between them, packing around the edges of the stamped plates, the lugs have the same height over the plane of the plate and made alternating, and the plates proper are installed between pressure plates with buckles; besides, the heat exchanger has protective pipe connections welded to the flat plates adjoining the pressure plates. EFFECT: reduced pressure loss of the flow of heat-transfer agent, enhanced reliability of leak-proofness of the packings, enhanced intensity of heat transfer. 4 dwg
