| Abstract: | Several factors affecting heat convection in cross flow along a bundle of spiral fin tubes were studied. Two-phase closed thermosyphons were used as heat transfer elements. Pleat transfer property and drag property were analysed and studied by experiment and data processing based on the principle of equal Reynold's number. Corresponding mathematical correlations are advanced, which provides foundation for design works in future. |

| Keywords: | cross flow along a bundle tube fin tube heat transfer coefficient of convection heat transfer coefficient of friction drag thermal resistance. |
