This study evaluates heat transfer characteristics of a sub-channels-inserted (SCI) porous heat removal device for divertor cooling. It is clarified that increasing the total volume of the sub-channels strongly contributes to the enhancement of phase-change of coolant as well as the vapor discharge. A high heat flux of approximately 25 MW/m2 is removed at a wall superheat less than 70 K by increasing the number of the sub-channels installed under low flow rate conditions. The results also suggest that the SCI porous heat removal device could be applicable for the divertor cooling by optimizing the subchannel design. Furthermore, especially for an enlarged heating area, optimizing the location of the sub-channel inlet, that is the interval of each sub-channel inlet, could be essential in order to smoothly discharge the generated vapor outside the porous medium.
