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).

Abstract: The invention relates to a heatsink for transferring heat from one or more electrical devices to a heat transfer medium. The heatsink includes a plurality of fins arranged on a frontside of the heatsink. The plurality of fins includes a first group of fins extending in a first planar direction and a second group of fins extending in a second planar direction angled in relation to the first planar direction. For example, the first group of fins may extend from the bottom to the top of the heatsink, while the second group of fins may extend from the first group of fins to the sides of the heatsink. In this way, the sides of the heatsink can be used as air outlets and the airflow through the heatsink can be increased.

Abstract: An apparatus (102; 202; 302; 402; 502) for transferring heat from a heat source (104) to air when the apparatus (102; 202; 302; 402; 502) is connected to the heat source (104) is disclosed. The apparatus (102; 202; 302; 402; 502) has a heat sink (106; 206; 306; 406; 506) comprising a heat sink base (108; 208) and a plurality of primary fins (110; 210) connected to the heat sink base (108; 208). Further, the apparatus (102; 202; 302; 402; 502) includes a heat sink front (112; 212; 412; 512). The heat sink base (108; 208) is configured to be thermally coupled to the heat source (104). Each primary fin (110; 210) of the plurality of primary fins (110; 210) has one or more conduits (114; 214). The heat sink base (108; 208) includes a first chamber (116; 216). The first chamber (116; 216) and the conduits (114; 214) together form a common space sealed off from the ambient air surrounding the apparatus (102; 202; 302; 402; 502). The first chamber (116; 216) and the conduits (114; 214) together enclose a heat-carrying fluid in the common space formed by the first chamber (116; 216) and the conduits (114; 214). By means of the common space, an efficient movement of the fluid is attained which allows the heated and/or evaporated fluid to move to essentially any part of the common space, which results in an improved heat spreading and heat transfer. A network access node for a wireless communication system is also provided, wherein the network access node comprises an apparatus (102; 202; 302; 402; 502) of the above-mentioned sort.
