STRUCTURE FROM WAVY SHEETS Russian patent published in 1998 - IPC

FIELD: mechanical engineering. SUBSTANCE: structure 10 consists of many mainly parallel wavy contacting sheets 12, 14. Riffles 22 form alternating peaks 28, 30 on sheets 12, 14. Peaks 28, 30 are connected by means of walls located at angle. Riffles 22 on each sheet 12, 14 are mainly parallel and are located at angle which differes from right angle relative to edge of sheets 12, 14. Adjacent sheets 12, 14 are so oriented that riffles 22 of one sheet 12, 14 intersect riffles of adjacent sheet 12, 24 at points of intersection of peaks 28, 30. Sheets 12, 14 have as a rule flat positioning projections located at some points of intersection of peaks of riffles of adjacent sheets. Peaks 28, 30 have pressed-in sections 42 between each two positioning projections. EFFECT: easily levelled structure from sheets with increased passage sections for flow of heat-transfer agents. 14 cl, 7 dwg
