Heat pipe

Abstract

A heat pipe is provided. The heat pipe includes a body, a first capillary structure, and a second capillary structure. The body has a hollow structure. The first capillary structure is disposed inside the body, extends in an axial direction of the body, and has a 3D structure. The second capillary structure surrounds the first capillary structure, is attached to a pipe wall of the body, and has a 2D structure. The first and second capillary structures are bonded together outside the body, and then they are disposed inside the hollow structure. The second capillary structure has an opening, from which the first capillary structure is exposed. The exposed portion of the first capillary structure is in contact with the pipe wall.
