Abstract

A thermal module directly press-forged from magnesium alloy is disclosed having a peripheral wall, a recessed chamber surrounded by the peripheral wall. The body is made of magnesium alloy by means of softening magnesium alloy with heat and then press forging softened magnesium alloy into the desired shape.

Claims

1. A thermal module comprising:

a body press-forged from a magnesium alloy material that is heated to a softened status, the body having;

a) a peripheral wall;

b) a recessed chamber surrounded by the peripheral wall;

c) an opening located at a top of the peripheral wall and communicating with the recessed chamber;

d) a base located at a bottom of the peripheral wall;

e) a plurality of radial fins located on an exterior of the peripheral wall and extending from the bottom to the top thereof; and

f) at least one reinforcing rib located on a bottom side of the body.

2. The thermal module according to claim 1, wherein the peripheral wall, the recessed chamber, the plurality of radial fins, and the at least one reinforcing rib are made of a pastille shape magnesium alloy by means of softening magnesium alloy with heat and then put in the die, and then the softened magnesium alloy is forged into shape.

3. The thermal module according to claim 1, wherein the base further comprises a plurality of mounting through holes extending through and spaced around a border of the base.

4. The thermal module according to claim 1, further comprising a barrel extending downwardly from a center of the base.

5. The thermal module according to claim 1, wherein the body has a shape selected from a group of shapes consisting of a circular shape, an oval shape, a triangular shape, a rectangular shape, a polygonal shape, and a streamline shape.
