A pump includes a pump flow path and electrodes and dielectric members in the pump flow path to allow a fluid to pass through the electrodes and the dielectric members in a flowing direction. The electrodes and the dielectric members are alternately stacked in the flowing direction so that a dielectric member is located between adjacent electrodes. Among the electrodes, an inter-electrode polarity of each pair of electrodes is different from that of an adjacent pair of electrodes. The dielectric members include a first dielectric member at a position of an odd-numbered dielectric member counted from the most upstream side of the flowing direction and a second dielectric member at a position of an even-numbered dielectric member counted from the most upstream side of the flowing direction. Material of the first and second dielectric members provide signs of a zeta potential opposite to each other.

Pump and cooling substrate

A cooling module includes an electroosmotic pump. The electroosmotic pump includes a first electrode which is permeable to a cooling fluid, a second electrode which is located with an interval from the first electrode and is permeable to the fluid, and a dielectric layer which is located between the first electrode and the second electrode and includes a microchannel which is permeable to the fluid. The first electrode and the second electrode have different polarities.
