Title: Heat exchanger having helically wound tube coils

Abstract: The heat exchanger is constructed with an axial guide such that the tube bunch can move axially within a cylindrical jacket in order to compensate for vibrations due, for example, to horizontal earthquake waves. Shoes are secured to the support plates to the tube coils and are slideably mounted within elongated slots in the jacket or vice versa. Should a vertical motion occur, the shoes are able to slide within the slots while the tube coils and their support plates remain supported within the jacket.
