The groove structures are disposed on an inner surface of the tube and extend to two opposite ends of the tube to reduce flow resistance of liquid phase working fluid. The evaporator wick is disposed in the evaporator section. The evaporator wick is made of metal powder and sintered to adhere to the groove structures. The evaporator wick is uniform in thickness and uniformly adheres to the groove structures. The evaporator wick vaporizes the working fluid in the evaporator section. As a result, the heat pipe has good manufacturing process repeatability and is reliable, easy to manufacture, and low-cost.
