This paper presents an improved thermal design\r\nmethodology for wind power converters. It combines analysis\r\nand experimental thermal design tools, including heat transfer\r\ncorrelations, flow network modeling (FNM), computational\r\nfluid dynamics (CFD), and experimental measurement techniques.\r\nMoreover, a systemic product development process is\r\nintroduced and an effective combination between the product\r\ndevelopment process and the thermal design methodology is\r\nachieved. The draftCFDmodeling at the initial design stage is\r\ndone. Furthermore, it uses the detailed CFD modeling and\r\nexperimental measurement techniques to provide a higher\r\ndegree of accuracy at latter design stages. The key advantage\r\nof the improved methodology is its emphasis on the use of\r\nvaried design tools, each of which is actively applied at its\r\noptimal point in the proposed product development process.\r\nThus, during the earlier stages of the product development\r\nprocess, the thermal risk is systematically reduced, and longterm\r\nreliability of products is maintained in a higher degree.
