摘要：

The two-phase loop thermosiphon is widely used in chip cooling combined with a fan and vibrates under the influence of the fan. In order to analyze the influence of vibration on the heat transfer characteristics, two-phase loop thermosiphons with a vibration frequency of 40 Hz and a vibration acceleration of 20 m center dot s(-2) were studied experimentally. The obtained results show that vibration does not change the change trend of temperature distribution and thermal resistance of a two-phase loop thermosiphon. However, vibration affects the heat transfer performance of the two-phase loop thermosiphon and the influence is affected by the coupling effect of the liquid filling rate. Also, vibration shortens the starting-up time of the two-phase loop thermosiphon and restrains the superheat of the evaporation section during starting-up processes.
