An Electro-Conjugate Fluid (ECF) is one of functional fluids. A strong jet flow is generated between two electrodes when a high voltage is applied to ECF through the electrodes. By the use of this strong jet flow, a pump with simple structure, no noise and no vibration can be developed. In this view point, authors had developed printed circuit board multi-layered type ECF-pump and tube type ECF-pump in order to realize a new liquid cooling system by ECF. And the performance of the liquid cooling system composed of printed circuit board multi-layered or tube type ECF-pump had been investigated. In this study, an ECF pump using two metallic meshes as electrodes is proposed. The proposed pump is fabricated, and experiments are performed to investigate the basic characteristics of the pump varying mesh size. These experimental results show that the existence of a suitable combination of metallic meshes is made clear and the proposed ECF pump has remarkable properties. In addition, the basic characteristics of this pump are investigated by carrying out experiments varying the width between two metric meshes of this pump. These experimental results show that this pump has remarkable properties when the width between two metric meshes is set at 0.1mm.
