Abstract
The present invention relates to an electric heater, which electrically and mechanically protects heating means from the outside, increases heating value and thermal conductivity by increasing contact efficiency among components, and improves assembly efficiency and productivity. The electric heater includes: a plurality of radiation members, each having a radiation fin and a radiation fin supporting plate surrounding the radiation fin and formed integrally with the radiation fin by brazing; a plurality of flat tubes arranged between the radiation members and having heating means therein for generating heat when electric power is supplied; first and second support frames oppositely arranged at sides of the outermost radiation members for supporting and fixing the radiation members and the flat tubes; and first and second caps for supporting both end portions of the first and second support frames and both end portions of the flat tubes.
