Abstract
A CPU heat exchanger comprises a plurality of curved metal thin pieces, each surface of each metal thin piece having punched with a plurality of ribs, the ribs at opposite sides being alternatively arranged; so that a trench is formed between two metal thin pieces for being formed with a turbulent flow; each rib having openings at an upper side and a lower side thereof. Airflow in the trench is turbulent and thus, air therein can absorb much heat. The openings on the upper and lower sides of each ribs cause air therein to expand and thus the heat can be absorbed more quickly. Therefore, cool and hot air are exchanged quickly.
