This study mainly experimentally investigates and explores the effects of local low-frequency vibrations on starting-up heat transfer characteristics pulsating pipe. A micro motors with vibration frequency 200 Hz were imposed external surface evaporation, condensation adiabatic section pipe, respectively, temperature average temperatures along evaporation as well thermal performances vibrating pipe scrutinized under different positions. The following important conclusions can be achieved by experimental study: 1) effect at time is more significant than that section. 2) positions reduce best heating power lower, higher. 3) resistance However, have little 4) effectively but no
