Abstract: A heat pipe comprises a tube and a wick structure. The tube includes a hollow chamber and has two sealed ends along an axial direction. The wick structure is disposed in the hollow chamber and extended along the axial direction of the tube. The wick structure has a first section near one of the sealed ends, a third section near the other of the sealed ends, and a second section between the first and third sections. The wick structure is composed of the first, the second and the third sections, and cross-sections of the first section, the second section and the third section in the axial direction are rectangles, respectively. A cross-sectional area of the first section is greater than that of the second and that of third section. The edge of each of the sections of the wick structure has a smooth form without the sectional difference.

Abstract: A heat pipe comprises a first pipe and at least a second pipe. The first pipe includes an evaporator, a heat insulator and a condenser communicating with each other to define a hollow chamber. The second pipe disposed in the hollow chamber includes an accommodating space and a first capillary structure disposed in one end of the accommodating space closer to the evaporator. At least one side of an outer pipe wall of the second pipe directly abuts an inner pipe wall of the first pipe. The first pipe further includes a second capillary structure disposed in the hollow chamber closer to the evaporator and extended to an outside of the second pipe and occupies at least 2/3 volume of the evaporator. A first part of the first capillary structure and the second capillary structure are connected to each other by winding so as to enhance transportation therebetween.
