Corrugated heater

The utility model relates to a corrugated heater which comprises a plurality of groups of heating bodies and corrugated radiation fins fixed at the two sides of each group of heating body; a heat conducting fin is attached onto one surface of each corrugated radiation fin away from each group of the heating body, and an aluminum foil film is respectively arranged between the heat conducting fin and the corrugated radiation fin and between the corrugated radiation fin and each group of heating body. The heat conducting fins are welded with the corrugated radiation fins by the aluminum foil films; and one surface of each corrugated radiation fin close to each group of heating body is welded with each group of heating body by the aluminum foil film. The corrugated radiation fins are attached at the two sides of each group of heating body; and the heat conducting fin is arranged between the adjacent corrugated radiation fins. In the corrugated heater, as the heat conducting fins are connected with the corrugated
