Résumé

Loop thermosyphon with multiple evaporators is an ideal equipment to achieve multi-source heat transfer with low energy consumption. In this paper, the transient response and oscillation characteristics of a loop thermosyphon with dual evaporators under different heating conditions, as well as the internal flow and interaction between the evaporators, are tested experimentally and visually. The results show that when the heating power is uniform, oscillation is more significant under higher heating power, which is due to the conflict and bypass flow between the evaporators; when the heating power of one evaporator is higher, outlet flow of the other evaporator is impeded to some extent and bypass flow from this evaporator to the other exists periodically. As a special case, when only one evaporator has heating power input, this bypass flow remains relatively stable; when the thermosyphon works at steady state, the working state changes smoothly if the heating power changes as step function.
