Bonded Fin HeatSinks
Bonded ?ncome in many different styles:
1. Mixedmaterials with aluminum ?ns and/or base
2. Epoxybonded or solder attachment
3. metal-to-metalswaged attachment
Advantagesof Bonded Fin:
1. Uniformthickness ?ns
2. Mixof aluminum in base or ?ns
3. Equivalentextrusion ratios of > 50:1
4. Finscan be cut to size or other fabrication before attachment
The bonded?n heat sink uses a grooved base plate designed to attach ?at ?n in set ?npitch or position. Grooves in the base are sized to accept set thickness of ?nand provide a high level of heat transfer from the base to the ?ns fordissipation to air. Good groove design and assembly adds very little addedtemperature rise to the overall heat sink performance. Some designs useextruded ?ns that are swaged or cold-formed in place by deforming the basematerial over the ?ns in their grooves.
Developedin the 1970s bonded ?n originally gave engineers the advantage of eliminatingthe problem of extrusion ratio limitation. A bonded ?n heat sink offeredextrusion ratios of >50:1 and above at a time that extrusions could onlyachieve 10:1. This gave the additional cooling surface needed to cool earlygeneration IGBT power modules and thermoelectric coolers when there were fewalternatives.
