The dynamics of straight tubes bundles in heat exchangers, in cross flow of coolant, is considered. The proposed mathematical model allows to determine quantity values which are fundamental in assessing the wear vibration intensity in contact points of tubes with intermediate supports taking into account gap values between tube and support. Tube vibration data obtained by application of this mathematical model (sliding path, contact tubes load in gaps, strain, response frequency structure) allow optimization of design parameters (gaps in intermediate supports, supports number and their location along the tubes length) and operational parameters of heat exchange equipment.
