Publication number: 20220361372Abstract: 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.Type: ApplicationFiled: July 22, 2022Publication date: November 10, 2022Inventors: Magnus KALLMARK, Fredrik OHLSSON, Vadim TSOI, Reine GRANSTROM

Publication number: 20210245449Abstract: 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.Type: ApplicationFiled: June 20, 2019Publication date: August 12, 2021Inventors: Nandan Khokar, David Carlstedt, Soraia Pimenta, Leif Asp, James M.
