Patent ID: 6901213

Claim:
An electric heater, comprising: a casing having a receiving compartment, an air outlet formed at a top side for communicating said receiving compartment to outside, and an air inlet formed at a bottom side thereof, wherein said casing further comprises a plurality of transverse supporters spacedly and transversely extended within said receiving compartment; a plurality of radiant conductive fins spacedly supported in said receiving compartment by said transverse supporters to define an air heating channel between each two said radiant conductive fins, wherein each of said radiant conductive fins has at least a guiding slot formed thereon, wherein each of said air heating channels is aligned between said air inlet and said air outlet for guiding air to flow along said air heating channels from said air inlet to said air outlet; and a heating element, having a diameter slightly smaller than a size of said guiding slot, electrically connected to a power source wherein said heating element is transversely extended to said radiant conductive fins through said guiding slots to define a gap between said heating element and said respective guiding slot, wherein when said heating element radially generates heat, said heat is radiantly distributed through said radiant conductive fins in a planar manner for heating up said air within said air heating channels so as to create heat flows therewithin to outside through said air outlet.
