Abstract

The present invention relates to an enamel-coating device and method for a fin tube and, more specifically, to a fin tube enamel-coating device for efficiently coating a fin tube with enamel. In order to achieve the purpose as described above, the present invention provides an enamel coating device for a fin tube which is short and is not deformed at a high temperature, the enamel coating device comprising: a transfer part for transferring a fin tube having a hollow tubular tube and a fin spirally formed on the outer peripheral surface of the tube; an applying part for applying an enamel powder on the fin tube charged by the transfer part; and a heating part positioned on either side of the applying part so as to heat the fin tube, wherein the enamel powder is a pure frit.
