1. 1. Cooling Strategies for Wave Power Conversion Systems

   Författare :Antoine Baudoin; Cecilia Boström; Anne Blavette; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave power; power conversion system; thermal management; power elctronics; passive cooling; natural convection.;

   Sammanfattning : The Division for Electricity of Uppsala University is developing a wave power concept. The energy of the ocean waves is harvested with wave energy converters, consisting of one buoy and one linear generator. The units are connected in a submerged substation. The mechanical design is kept as simple as possible to ensure reliability. LÄS MER
