Positioning and buckling structure for use in a radiator

A positioning and buckling structure adapted for use in a radiator, the radiator including a plurality of metal plates each having a main body and a side folded portion connecting at least one of two opposite sides of the main body, the positioning and buckling structure disposed on each of the metal plates, the positioning and buckling structure comprising:

• a snapping piece extending from a front edge of the side folded portion, having a fork-like shape portion with two corresponding sides, a cleaved opening formed between the two corresponding sides, a guiding revised angle structure formed on and outwardly extending from an end of each of the two corresponding sides, and a hooking portion disposed on and extending from the guiding revised angle structure;
• and
• a buckling slot formed on a rear edge of the side folded portion and corresponding to the snapping piece, the buckling slot communicating with a rear opening formed at a bottom of each of the metal plates, and having a width thereof smaller than a width of the snapping piece and larger than a width of the rear opening;
• wherein the metal plates are stacked together side by side for inserting the snapping piece of each of the metal plates into the buckling slot of an adjacent metal plate, wherein the snapping piece engages the buckling slot by penetrating through the rear opening and clamping two sides of the buckling slot by the hooking portion.
