风冷IGBT散热器正交设计及优化研究
Orthogonal Design and Optimization Research on Air-cooled IGBT Heatsink
摘要
Abstract
Based on the heat dissipation requirements of a certain engineering power device and the size restriction requirements of the heat sink,it is planned to seek a cooling design solution with better performance.Combining the basic theory of heat dissipation,and using the bottom-top and compact design as the principle,it is designed by orthogonal analysis and compared the basic properties of the radiator under different structural schemes.Considering the performance and fan selection,the results show that in the size of the shape and structure,the length of the radiator has the most impact on the air resistance and thermal resistance performance of the radiator.The size of the heat dissipation substrate and the fin also has an preferred range.The comprehensive manufacturing process,the preferred recommendation value of the thickness of the heat dissipation fins is 2～4 mm.The use of wind absorption is more conducive to heat dissipation design.When the ratio of the distance between the IGBT to the air outlet side and its adjacent spacing is within the range of 1～2,it is most beneficial to the heat dissipation design.Compared with the design limit,the optimized solution improves the heat dissipation performance by 16%and the occupied volume decreases by 64.43%.关键词
