Claim 0:
1. A heat pipe, comprising:
a first pipe including an evaporator, a heat insulator and a condenser which communicate with each other to define a hollow chamber, wherein two ends of the first pipe along an axial direction of the heat pipe are sealed; and
at least a second pipe disposed in the hollow chamber and including an accommodating space and a first capillary structure disposed in one end of the accommodating space closer to the evaporator;
wherein 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 which is 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,
wherein the second capillary structure has an uninterrupted section which is folded up multiple times in the evaporator.
