SIDE MATERIAL AND METHOD FOR ITS MANUFACTURE, AND MANUFACTURING METHOD OF PLATED ELEMENT FOR HEAT EXCHANGER Russian patent published in 2012 - IPC F28F21/08 

FIELD: power industry.

SUBSTANCE: plated element for heat exchanger includes core material and one or more layers of side material laminated on one of its sides or both of its sides. Multiple small grooves (B) which are periodic and arc-shaped in longitudinal direction of side material are formed on surface of side material (A). Grooves are spread to external peripheral edge of side material and have curvature radius of 800-1500 mm and period (D) of 1-8 mm in the above direction. Roughness of surface of side material (A) comprises 1-15 mcm as per the average at 10 roughness points (Rz). Side material is made by cutting the ingot into material of the specified thickness and alignment in horizontal position with longitudinal direction of the cut material. Centre of rotating disc device corresponds to ingot centre as to width. Occurrence of bad adhesion between material of core and side material is prevented due to controlling the state of surface and flatness of side material.

EFFECT: improving corrosion resistance of plated element and increasing the heat exchanger obtaining process efficiency.
