NOVELTY - This utility model is based on first wall part of double cooling fusion reactor of graphene heat conducting, comprising a wall member for forming a first support structure, the body shape is U-shaped groove-shaped structure, the bottom of the U-shaped groove-shaped structure facing a surface plasma coated high temperature corrosion resistance, in the supporting body of the U-shaped groove-shaped structure is provided with a cooling flow passage and the cooling flow passage is double the cooling flow channel. This utility model through the dual cooling flow passage for cooling, quickly take away the heat on the first wall, enhancing the heat transfer of the first wall, further reinforcing the mechanical safety of the heat of the first wall structure -. At the same time, because the high efficiency of heat conduction efficiency, good neutron economy and mechanical safety and so on, can be applied to future deuterium-tritium fusion energy exemplary stack plasma-facing component, has important engineering practical value.
