Heat Exchanger Tube Spacing Device (Varinats)

A heat exchanger devices for operations in heavy liquid metal coolant mediums that ensures reliable fixation and spacing of heat exchanger tubes. A first option includes one supporting spacer grid 1 consisting of a cylindrical shell 2 and two or more tiers of plates 3 and 4 spaced apart at the preset gap, while the width of each plate lies within the plane which is parallel to the shell axis; ends of all plates are fixed to the shell such that plates of any tier are parallel to each other and located at the preset gap; plates of different tiers are criss-crossed at an angle of 60 degrees along the shell axles and fastened together at the crossing points. A second option includes three dividers which run through the cylinder axis; their ends are connected to the shell and are spaced at an angle of 60 degrees.
