COUNTER-CURRENT PLATE-TYPE HEAT EXCHANGER Russian patent published in 2001 - IPC

FIELD: heat exchange equipment, applicable for heat exchange between various liquids, mainly in heat supply systems. SUBSTANCE: the heat exchanger has a pack of plates 1 with corrugations located in the form of an embossed "herringbone" with angular holes for feeding and discharge of liquid to the heat exchange section, the pack is installed on guide rods and squeezed between the bed and the pressure plate by studs inlet and outlet connections that are made curvilinear and attached to the bed and the plate, their ends extent beyond the outside clearance of the heat exchanger. Corrugations on each plate are made by groups, which are positioned in succession over the entire length of the plate, besides corrugations in a group are arranged in rows, and each row of corrugations has a different length l₁, l₂, l₃, l₄. EFFECT: enhanced intensification of heat exchange. 2 cl, 3 dwg
