Claims
- 1. The method of forming fins for a gas heat exchanger for heating or cooling an object comprising,
- cutting a plurality of right-angle triangle shaped fins out of a thermally conductive metal with adjacent fins being connected adjacent corresponding sides of each fin,
- folding the tip of each of said triangular shaped fins opposite its connected side over and against its fin, and
- folding adjacent fins along their connection to each other towards each other in a direction whereby adjacent fins are reversed relative to each other.
- 2. The method of forming a heat sink for cooling an electronic package comprising,
- removing material from one side of a solid piece of thermal conductive material at a plurality of spaced first positions leaving a cross-sectional area having a bottom, a top, and a side which extends downwardly and outwardly from the top to the bottom, and
- removing material from the side opposite the one side at a position between each of the plurality of first positions to leave a second cross-sectional area similarly shaped to the first cross-sectional area but reversed.
- 3. The method of forming fins for a gas cooled heat sink for cooling an electronic package comprising,
- forming a parallelogram shaped fin having one side approximately forty five degrees relative to an adjacent side, and
- folding the fin in the middle to form double fins positioned adjacent to each other but extending from the middle in opposite directions to each other.
- 4. The method of claim 3 including leaving a space between the doubled fins after folding.
