Disclosed is a conformal cooling channel design method using a topology optimization design. The conformal cooling channel design method using a topology optimization design according to an embodiment of the present invention includes the steps of: determining classifying molded products into a thin structure or a bulk structure and determining an area to be cooled; disassembling the area to be cooled into two-dimensional-shaped surfaces to be cooled; forming cooling channels independent from each other with respect to the surfaces to be cooled, respectively, by using the topology optimization design; and combining the cooling channels with each other to form a conformal cooling channel. The present embodiment provides a method in which shapes of molded products are classified into three-dimensional or two-dimensional shapes to determine a surface to be cooled, an independent cooling channel is formed for each surface to be cooled by using a topology optimization design, and then a conformal cooling channel to the inside of a mold is designed.
