The invention discloses a U-shaped device for adjacent cooling channels of a first wall of a divertor of a fusion device and an assembly method of the U-shaped device. The U-shaped device comprises ashell, an upper module and a lower module, wherein the shell comprises a shell body and a T-shaped limiting block, the shell body is of a plate shell type structure, two through holes are formed in the upper surface of the shell body, and a groove is formed in the shell body; the upper module can be completely embedded into the lower module to form an assembly, and meanwhile, the upper surface ofthe upper module is flush with the upper surface of the lower module; the assembly can be inserted into the shell body, and meanwhile, two inclined planes and the lower end face of the lower part of the assembly are flush with two corresponding inclined planes and the lower end face of the shell body. According to the invention, a three-component scheme design is adopted, and a plurality of welding processes are combined,
