摘　　要：设计了一种压电泵驱动闭式水冷回路传热系统,压电泵采用双腔串联结构,在150 V驱动电压下,泵水流量达330 mL/min。为了分析水蒸气对压电泵驱动闭式水冷回路传热性能影响,该文采用实验方法研究了不同充液率下压电泵驱动水冷回路的启动和稳态工作特点。实验结果表明,闭式回路内压电泵在充液率大于0.895时才能启动。当充液率大于0.930时,少量气相的存在对压电泵及传热系统的工作性能影响较小,系统传热热阻小于0.2℃/W。A heat transfer system of water cooling closed-loop driven by the piezoelectric pump is designed in this paper.The piezoelectric pump adopts a dual-chamber series structure,and the water flow of the pump reaches 330 mL/min at the driving voltage of 150 V.In order to quantitatively analyze the influence of the vapor phase on the heat transfer performance of the water cooling closed-loop driven by the piezoelectric pump,an experimental investigation was carried out to study the influences of different filling ratio on the start-up and steady-state operating characteristics of the piezoelectric pump driven closed-loop.The experimental results show that the piezoelectric pump in the closed-loop can only be started at a fluid filling ratio of great than 0.895.When the filling ratio is great than 0.930,the presence of a small amount of vapor phase has little influence on the operating performance of the piezoelectric pump and the heat transfer system and the thermal resistance of the system is lower than 0.2℃/W.
