Abstract: The present invention provides a radiator that consists of a plurality of f ins, one side of each fin has at least one wing parallel relative to the side, the wing is disposed spaced from the fin. The wing has protruding parts disposed approximately perpendicularly to the wing. The fin has slots positioned relative to a corresponding protruding part. The protruding parts engage with the slots and the protruding parts are bent such that the fins are combined into a radiator. The radiator has following characteristics: simple structure, easily assembled, robust, easily formed, and material-saving.

Abstract: The present invention provides a radiator that consists of a plurality of fins, one side of the fin has at least one wing parallel relative to the side, the wing disposed spaced from the fin. The wing has protruding parts disposed approximately perpendicularly to the wing. The fin has holes on the corresponding position relative to the said protruding part. The protruding parts engage with holes and the protruding part being bend then those fins will be combined into a radiator. The radiator has the following characters: simple structure, easily assemble, strong-linked, anti-break off stable-shaped, easily molding, material-save.
