摘要: In this paper, a novel heat sink which coupling natural convection and phase transition was designed to meet the cooling requirements of distribution level static synchronous compensator (DSTATCOM). The two inclined evaporation substrates can for parallel operation DSTATCOM working medium R245fa driven by gravity buoyancy in sink. influence filling ratio heating power on thermal performance investigated experimentally theoretically. experimental results showed that had significant At ambient temperature 25°C, could start up successfully at different ratio. Meanwhile, achieved good dissipation as maximum were 60.14°C 67.85°C while 3000 W 80%. transfer resistance between condensation 6.6×10−3°C/W 1.2×10−2°C/W same condition. Additionally, agreement with calculated results.
