Abstract The tube bundle support is ponent in tubular heat exchanger. Change of the structure and the shape of bundle
support is animportant mean to enhance heat transfer. In this paper, structural and heat transfer characteristics of arch baffles, circle
orifice p lates, rod baffles, helical baffles, hollow circles, self support structures, anti vibration baffles and twisted tape elements were
described and analyzed in detail, and heat transfer performance of the various supporting were pared. Every tube bundle
supporting has own characteristics and work environment, and its advantages or disadvantageswere relative. But, the general development
