Claims

[Claims for Utility Model Registration] A frame having first and second flat plate portions formed by bending a sheet of aluminum thin plate and arranged parallel to each other, and an intermediate connecting plate portion connected between one end of these flat plate portions. In the aluminum heat dissipating body formed of a frame body, corrugated fins loaded into the frame body, and integrated by brazing, the strip-shaped thin aluminum plate is formed at a boundary portion between the flat plate portion and the intermediate connecting plate portion. 1. An aluminum heat sink characterized by being bent at easy-to-bend portions such as grooves or creases.
