Abstract

A radiator with positioning and buckling structure includes multiple metal plates, each of which has a main body, and a folded side portion is connected to one or two sides of the main body. The positioning and buckling structure is disposed on each of the metal plates. The positioning and buckling structure includes a snapping piece extending from the folded side portion. The snapping piece has a cleaved groove thereon and at two sides of the snapping piece there is provided two hooking portions. A buckling slot is disposed on the folded side portion of the metal plate corresponding to the snapping piece. The buckling slot is connected to a rear opening having a smaller width than the width of the snapping piece so that the metal plates can be stacked together.

Claims

1. 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:

2. The positioning and buckling structure as claimed in claim 1 wherein the folded side portion is connected with the lower side of the main body.

3. The positioning and buckling structure as claimed in claim 1 wherein the folded side portion is connected to a lower side and a upper side of the main body.

4. The positioning and buckling structure as claimed in claim 1 wherein guiding reverse angle structures are provided at the two corners of the front hooking portions.

5. The positioning and buckling structure as claimed in claim 1 wherein the rear opening has an increasing width to form inclined sidewalls at the rear opening.

6. The positioning and buckling structure as claimed in claim 1 further comprising a heat dissipating substrate being connected with the folded side portions of the metal plates.
