  • Publication number: 20220361372
    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.

  • Publication number: 20220294478
    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.

  • Publication number: 20210245449
    Abstract: Novel ultra-thin unidirectional pre-preg tapes are disclosed. They can be used to produce ultra-thin woven, bias, multiaxial, chopped-oriented etc. types of pre-pregs. These ultra-thin pre-pregs enable production of composite material products with well-controlled dimensional tolerances and smooth/even surfaces. Further, they render the production of composite material products relatively simpler, tidier, quicker, and economical. The obtained composite material products are relatively thinner, lighter, and mechanically higher-performing.
