Abstract

With recent technological developments in various industries, the heat flux of electronic components is rapidly increasing due to their miniaturization and high performance. To reliably and efficiently cool these high-heat flux electronic components, the heat transfer coefficient may be improved using phase change: a vapor chamber is a typical example of such a cooling device. Recently, research on vapor chambers using metal additive manufacturing methods has also been conducted. Accordingly, in this study, the capillary wicking performance of grooved wick for vapor chambers was examined using a metal additive manufacturing method. The wicking performance was investigated according to the printing directions, cutting methods, and geometrical parameters of the groove wick, and evaluated considering the wicking distance and maximum reach height over time. Acetone and Novec 649 were adopted as working fluids, and differences between the experimental and theoretical values for the wicking performance were compared and analyzed.
