Abstract
An exemplary heat pipe includes an elongated casing, a wick, an artery mesh, and working medium filled in the casing. The casing includes an evaporating section and a condensing section. The wick is disposed within an inner wall of the evaporating section of the casing. The artery mesh includes a large portion, and a small portion with an outer diameter smaller than that of the large portion. The small portion is located within and in direct physical contact with an inner surface of the wick. The large portion is in direct physical contact with an inner wall of the condensing section of the casing. The working medium saturates the wick and the artery mesh.
