Résumé
Two-phase loop thermosyphon with multiple evaporators is ideal device to achieve multi-source heat transfer and has great application potential. As there are parallel branches in the loop, unstable phenomena often exist. In this paper, the instability of a two-phase loop thermosyphon with three evaporators is investigated experimentally. The results show that the oscillation frequency increases while the amplitude almost remains constant with the increase of heating power; The oscillation frequency decreases slightly while the amplitude increases with the increase filling ratio; In the oscillation, when the temperature of an evaporator reaches the peak value, the temperatures of the adjacent evaporators reach the trough value.
