Microscale Electro-Hydrodynamic (EHD) Modular Cartridge Pump
- Magazine Article
The EHD pump uses electric fields to move a dielectric fluid coolant in a thermal loop to dissipate heat generated by electrical components with a low-power system. The pump has only a few key components and no moving parts, increasing the simplicity and robustness of the system. In addition, the lightweight pump consumes very little power during operation and is modular in nature. The pump design takes a modular approach to the pumping sections by means of an electrically insulating cartridge casing that houses the high-voltage and ground electrodes along with spacers that act as both an insulator and flow channel for the dielectric fluid.
