1. A wick structure of a heat pipe, comprising
a plurality of wicks provided inside a heat pipe,
wherein the plurality of wicks include:
a first wick provided at one side of a length direction to correspond to a condenser section of a heat pipe;
a second wick having one side elongated to be connected to the first wick and provided at an adiabatic section of the heat pipe; and
a third wick having one side connected to the other side of the second wick to correspond to an evaporator section of the heat pipe and provided at the other side in the length direction, and
the first wick and the second wick have effective pore radiuses and pore structures that are different from the third wick, and the first wick, the second wick, and the third wick maintain a movement and a capillary force of a working fluid supplied to the inside of the heat pipe when bending the heat pipe,
wherein
the first wick and the second wick are integrally formed with the same effective pore radius and structure as each other, and
the first wick and the second wick are installed to be separated from the inner surface of the heat pipe.
