Especially in the case of strip-shaped capillary tissue (such as axially woven fiber capillary tissue), it is difficult to maintain a straight line in the heat pipe due to its elongated shape, so it can only be sintered by sintering after the tube is placed. It is fixed in the pipe body, but before sintering, when it is placed in the pipe body, there is no special mold for shaping, or because the residual stress of the material causes deformation and loses the predetermined straight line shape, resulting in subsequent sintering positioning. The shape of the heat pipe is not as expected, and even the heat pipe body is sunken during the degassing operation, which affects the original design intention of the capillary structure.
