FIELD: heating.SUBSTANCE: present invention relates to versions of the spacing device intended for heat exchanger tubes, primarily for operation in a heavy liquid metal heat carrier. First version device contains at least one support-spacer grid 1, each consisting from cylindrical housing 2 and two, three or more tiers bars 3 and 4 spaced from each other to preset gap, width of each plate is located in plane parallel to axis of the housing and ends of all plates are attached to the housing so that plates of any tier are spaced apart with preset gap in parallel to each other; herewith plates of both tiers are crossed at angle 60 degrees if seen along body axis and are interconnected in areas of said crossing. Second version device has three sectioning partition passing through axis of the cylinder and attached by their ends to the body and shifted from each other at angle of 60 degrees.EFFECT: more reliable fixation of heat exchanger tubes with their simultaneous spacing.11 cl, 4 dwg |
