Bonded Fin Heat Sinks

High Power - Bonded Fin Heat Sinks - Series BF
All types are available in any desired length and fin height. Faster airflow and taller fin height improve the thermal values.

High Power - Bonded Fin Heat Sinks - Series BFV
Both types are also available in other lengths than listed on datasheet. Higher air flow volume improves the thermal value. Parts are also available with 220VAC or 12 VdC fans fitted.

On request parts can be supplied with a surface finish. The thermal resistance values shown in the tables are examples which refer to the value indicated in the footnote on the pdf datasheets, which are available to download. Customer specific designs are welcome. Please send us your requirements.

Innovative High Power - Bonded Fin Heat Sinks - Series IHM/IHV
This new design offers many benefits over conventional heatsinks with standard flat baseplate. The series IHM/IHV has been developed especially for IGBT with outside dimensions of 130 x 140 mm and 190 x 140 mm.

Because of a small fin distance the most possible heat transfer per volume unit is achieved.
Due to the special shape of the baseplate, a 20 to 25% higher heat dissipation is achieved as compared to conventional baseplate designs.
Typical properties of these heatsinks are: small temperature gradient, high latent heat capacity, high heat time constant.
The thermal resistance depends on the length and air flow volume (m3/s). Any desired length can be supplied. On request the IHM/IHV heat sinks can be supplied with fan.
