Abstract
A heat pipe operating noiselessly by preventing, or reducing the effects of, the mixing of working fluid at different temperatures includes a hollow tube, a capillary structure, a working fluid, and a bushing. The porous capillary structure able to carry the fluid is disposed on an inner wall of the tube. The bushing is hollow, and the bushing is disposed on a surface of the capillary structure away from the tube. The heat pipe is divided into evaporation, adiabatic, and condensation sections, the capillary structure being at all sections. The working fluid is disposed in the capillary structure of the evaporation section, the bushing is disposed on a side of the capillary structure of the adiabatic section.
