METHOD AND APPARATUS FOR LOW-COST ELECTROKINETIC PUMP MANUFACTURING

WIPO Patent Application WO2004076857

A3

An electroosmotic pump (22) used in a closed loop cooling system (10). The pump includes a fluid chamber, a pumping element (104), an inlet electrode (1 12A), an outlet electrode (112B), and means for providing electrical voltage to the inlet electrode and the outlet electrode to produce an electrical field therebetween. The pumping element is configured to pump fluid therethrough, and the pumping element is positioned to segment the fluid chamber into an inlet chamber (142) including a fluid inlet port (126) and an outlet chamber (140) including a fluid outlet port (124). The size of the inlet chamber is proportional to a predetermined residence time of the inlet chamber. The inlet electrode is positioned within the inlet chamber and a predetermined distance from the first surface of the pumping element. The outlet electrode is positioned within the outlet chamber and a predetermined distance from a second surface of the pumping element.
