The invention discloses an enamelling method of an enamel heat transfer element, comprising the following steps of: (1) preparing enamel frit for later use; (2) making an electrostatic enamel powder which can be sprayed by the use of an electrostatic spray gun; (3) making glaze slip which can be used for wet spraying; (4) spraying the glaze slip obtained from the step (3) on the heat transfer element's grooves and slots which are not easy to spray by an electrostatic dry method; (5) drying the heat transfer element sprayed by the step (4), sending the dried heat transfer element into an electrostatic spraying device, and spraying the electrostatic enamel powder by using the electrostatic spray gun; (6) sending the heat transfer element which has undergone the above steps into a high temperature enamelling kiln for sintering, and cooling to obtain enamel heat transfer element with anticorrosion performance. According to the workpiece sprayed by the enamelling method of the enamel heat transfer element, enamels are greatly wrapped by edges after sintering. In addition, the grooves of the heat transfer element are greatly coated with enamel. The enamelling method is suitable for various shapes and wave patterns.
