FIELD: machine building. ^ SUBSTANCE: unit of cooling stack sprinkler consists of vertical layers of parallel net pipes made out of thermo-plastic material and welded between them on ends of unit at points of contact. Also, pipes are made as prisms with cross section in form of equilateral octahedron with rounded angles. A shell of the prism is latticed as a net of rhombic form with acute angle 30-45 to horizontal surface. ^ EFFECT: simplified design and increased strength, raised output, and improved efficiency of cooling re-circulated water in cooling stack. ^ 2 cl, 4 dwg |
