| 摘要 |
The present invention is related to a heat sink unit comprising a base (1) and a number of fins extending from the base, said heat sink unit having an extended surface area formed by microfins (2) inserted between the extruded fins. The microfins are formed by folding a strip having a clad braze layer on both sides. The microfins are preferably brazed to the extruded structure by heating the structure after the fins have been inserted to a temperature higher than the melting point of the clad braze. <IMAGE> |
