Abstract
An enclosed heat sink with a side wall structure is provided. The side wall structure includes a welding body having a first welding plane and a side wall structure having a second welding plane. The first welding plane and the second welding plane are pressured and welded to each other, such that the welding body and the side wall structure encapsulate a cavity. A width of the second welding plane is smaller than a width between two side surfaces of the side wall structure.
