Porous metal fin was used as boiling heat transfer plate of phase change devices. The number of cells of the porous metal fin is 8 ppi, and the pore diameter of the porous metal fin is 3.1 mm. On the boiling heat transfer surfaces, the porous metal fin and the bass plate are brazed. Three samples of boiling heat transfer plates with the porous metal fin were made as prototype. Working fluids are HFE7000 and HFE7100 made by 3M. Predicting method of the boiling heat transfer coefficient was based on the expansion ratio of effective area to the flat plate and the correlation of that of Stephan's equation. The boiling heat transfer coefficient in the heat transfer plate with surface roughing process of concave can be put in order by ± 10 %.
