Abstract

According to an embodiment, a wick structure of a heat pipe that is capable of bending while increasing a heat transferring operation limit value is provided by improving the wick structure provided inside the heat pipe. The wick structure of the heat pipe includes 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, the second wick and the third wick have effective pore radiuses and pore structures that are different from each other and maintain a movement and a capillary force of an working fluid supplied to the inside of the heat pipe when bending the heat pipe.
