ABSTRACT OF THE DISCLOSURE The disclosure herein describes a heat exchanger which is provided with a plurality of linear heat exchange tubes arranged in array of concentric circular rows with their axes vertical and parallel; a cylindrical casing surrounds the linear heat exchange tubes and a plurality of concentric supporting systems maintain the arrangement of a circular row of the heat exchange tubes by permitting lateral deflecting movement of the tubes at certain movable axial levels while securely maintaining the tubes in vertical alignment at a plurality of certain axial fixed levels. Each supporting system consists of a circular strip having alternate trapezoidal cells and welded to a supporting strip. Some of the tube supporting systems at the moveable axial levels are independent of the tubes supporting system concentrically adjacent, in radial direction, in order to permit certain of the circular rows of the heat exchange tubes to undergo expansion differing from the thermal expansion of the tubes of others of the circular rows without exerting damaging mechanical stresses on the tubes supporting systems.
