Coating method, apparatus for coating and coating improve heat dissipation

摘要

PROBLEM TO BE SOLVED: To provide a novel coating method capable of improving heat radiation of a coated object.SOLUTION: According to the invention, there is provided a coating method for improving heat radiation of a coated object, comprising a step of performing spray-coating on a surface to be coated with paint containing a pitch-based carbon fiber as an aggregate. In the invention, a periodic uneven structure may be formed on the surface to be coated by spray-coating on a surface to be coated with paint containing the pitch-based carbon fiber as the aggregate in a plurality of lines . Therefore, the surface to be coated may also be performed spray-coating with the paint such that a line of aggregate-rich paint and a line of aggregate-poor paint may be alternately adjacent to each other, and after a ground layer is formed by spray-coating on the surface to be coated with the paint uniformly, the spray-coating may also be performed with the paint such that the lines of the paint may be spaced at predetermined intervals over the ground layer.SELECTED DRAWING: Figure 1
