The heat dissipation unit 21 includes a first side plate 211 and a second side plate 212, the top of the first side plate 211 and the top of the second side plate 212 are connected through a top plate 214, bottom plates 213 connected to the top surface of the bottom plate 10 are disposed at the bottom of the first side plate 211 and the bottom of the second side plate 212, and the first side plate 211 are both provided with air vents 215. Specifically, the bottom plate 213 and the bottom plate 10 may be connected by riveting, welding, or high-temperature molten metal bonding.

As described above, the fin structure 20 is formed by bending a sheet, and the heat sink does not need to be molded by casting, so that the cost of the heat sink can be reduced, and the heat sink can rapidly dissipate heat with a small thickness of the sheet.

The front side and the rear side of the bottom plate 10 are both turned upwards to form a first folding edge 11, and the fin structure 20 is located between the first folding edges 11 on the front side and the rear side of the bottom plate 10. The fin structure 20 can be positioned by the first folded edge 11, and alignment between the fin structure 20 and the base plate 10 can be facilitated during production.
