Abstract: A device for transferring heat between a second module, for example an optical transceiver module, and a first module, for example a heat sink. The device comprises a holder for holding the second module, a first unit configured to be thermally coupled to the first module, and a second unit which is urged against the second module placed in the holder by a biasing apparatus. The first unit and the second unit are thermally coupled to one another through a heat-transferring apparatus such that an improved heat transfer can be provided between the first and second units, and hence between the second module and the first module. Furthermore, the disclosure also relates to an arrangement, including the device, and a network access node for a wireless communication system including any one of the device and the arrangement.

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.

Abstract: A radome assembly includes a radome member, a heat sink member, a seal member disposed between the radome member and the heat sink member, and a frame assembly configured to compress the seal member between the radome member and the heat sink member. The frame assembly includes a fixation member configured to be fixedly engaged with the heat sink member and an arm member, the arm member configured to engage the radome member to compress the seal member between the radome member and the heat sink member when the fixation member is engaged with the heat sink member, and wherein engagement of the fixation member with the heat sink member in a compressed state of the seal member forms a gap between the radome member and the heat sink member.
