CAPILLARY WICK HAVING COMPOSITE LATTICE STRUCTURE FOR HEAT PIPE, HEAT PIPE INCLUDING SAME, AND MANUFACTURING METHOD THEREFOR
A heat pipe including a capillary wick of a composite lattice structure, according to the present invention, includes a capillary wick inserted axially into the inside of a pipe main body, wherein the capillary wick has a structure in which a plurality of lattice layers having lattice structures with different pore sizes are stacked radially, thereby securing capillary force from the outer side to the inner side of the inside of the heat pipe and also increasing transportation capacity of liquid by increasing permeability of liquid at the outer side of the inside of the heat pipe and thus improving the heat conduction rate of the heat pipe. In addition, since the capillary wick according to the present invention is manufactured using 3D printing technology, the capillary wick in which a lattice structure having a complex shape is stacked in a plurality of layers may be more easily manufactured. In addition, according to the present invention, since a wick structure does not need to be additionally processed on the inner wall of the pipe body, the heat pipe may be easily configured and manufactured, and may be applied to existing pipe bodies.
