The radiator pieces by the S-shaped pipe and embedded in the outer pipe wall between the heat sink sheet composition, the traditional production process is generally used to weld the pipe and the wing piece connection, which requires the pipe wall and sheet with a certain thickness, and fewer connection points, not solid, heat transfer, heat dissipation effect is not ideal.

And the use of 3D printing can realize the integration of heat dissipation, to ensure that the connection is solid while realizing the minimum wall thickness (heat sink thickness of 0.3mm, to achieve the best heat transfer structure and a larger heat dissipation surface heat sink more).
