Abstract
An Electro Hydro Dynamic, EHD, thruster (105) comprising a first set of electrodes (210), a second set of electrodes (220) and a supporting structure (103) for supporting the first set of electrodes (210) and the second set of electrodes (220). The EHD thruster (105) is configured to generate airflow of ionised air for cooling a heat sink (101). Further, the EHD thruster (105) is electrically isolated from the heat sink (101).
