Medium Power - Pressed Fin Heat Sinks - Series PF PF is a series of heat sinks for medium power applications which allows a wide variety of different widths without the need of additional tooling. By pressing together numerous single fins, any required heat sink width can be created. Due to the special assembling process assembled units have nearly the same resistance against mechanical stress as a heat sink made from a single piece of aluminium.
High Power - Pressed Fin Heat Sinks - Series PRE/PRD In addition to the bonded Fin Series BF DAU has developed a new heat sink concept Series PRE/PRD which is build equivalent to BF Series from two major components - the base section and the fin section.
Series PRE/PRD the fins will be assembled to the base plate by a special developed and patented pending, cold welding process instead of using thermal conductive glue. This assembling process ensures lowest thermal resistance between the base plate and the fins and allows therefore a nearly perfect heat transfer from the base plate to the fins.
