典型电流体动力学传导泵性能的实验研究

为考查典型电流体动力学传导泵性能，推动其应用于电子元器件微通道液冷，设计了平嵌电极与多孔电极电导泵，并搭建电导泵实验系统，测试了这2种电导泵泵送介电液体HFE-7100的性能。结果表明:施加10 kV直流电压时，6对平嵌电极电导泵产生流量194.5 mL/min，动压40.3 Pa，最大静压72.1 Pa；3对孔径为1.5 mm的多孔电极电导泵产生流量438.2 mL/min，动压173.0 Pa，最大静压363.5 Pa。可见，相比平嵌电极电导泵，多孔电极电导泵具有更好的性能。

Experimental study of performance of typical electrohydrodynamic conduction pumping

In order to test the performance of typical electrohydrodynamic(EHD) conduction pumps and promote their applications in the microchannel liquid cooling of the electronic components, the flushed electrode and perforated electrode EHD conduction pumps are designed, and an experimental system of the EHD conduction pumping is established to test the performance of the two typical kinds of the EHD conduction pumps to transport the dielectric liquid HFE-7100. It is shown that at the applied voltage of 10 kV DC, the flow rate, the dynamic pressure, and the maximum static pressure of the EHD conduction pumping with six pairs of flushed electrodes are 194.5 mL/min, 40.3 Pa, and 72.1 Pa, respectively; while the flow rate, the dynamic pressure, and the maximum static pressure for three pairs of the perforated electrode EHD conduction pumping with a diameter of 1.5 mm are 438.2 mL/min, 173.0 Pa, and 363.5 Pa, respectively. So it can be said that the perforated electrode has better performance than the flushed electrode.
