Cooling technique for divertor with metal porous media

We proposed cooling technique using sintered metal porous media. This cooling technique is based on heat removal by latent heat of vaporization of coolant flowing in the porous media. One side of the porous media is touched to high heat load surface, and the other side is soaked in coolant. Coolant penetrates into the porous media and evaporates due to transmitted heat.

Advantages of the cooling system are as follows.

• Thermal energy is transmitted into the inside of coolant because large thermal conductivity of metal material.
  
• Coolant is given to the high heat load surface continuously because of sintered metal porous media's capillary force. That prevent the coolant from transforming to the film boiling state.
• High temperature steam is available because of making coolant evaporate positively.
