Manufacturing process improves efficiency of heatsinks

Claimed to produce a more efficient heatsink design than bonded fin heatsinks, created by compression/bonding, Fischer Elektronik uses solid aluminium to produce heatsinks in any geometry and to customer-specific requirements. The KGR series heatsinks are made of one piece, meaning that the heat transfer from the heatsink’s base plate to the individual fins takes place in the same basic material. This is claimed to markedly improve it even further from a heat perspective. In addition, the fin coolers can also be provided with a better surface coating in a further process as no thermal adhesive will act as a barrier, particularly in critical applications, such as medical devices, or installation locations with a high humidity.

Currently, the heatsinks can be manufactured up to a maximum width of 250mm with base thicknesses from 4.0 to 20mm and a minimum fin thickness of 0.8mm for 2.0, 2.5, 3.0, 4.0 or 5.0mm fin spacings. The greatest fin height, at the moment and without the thickness of the base plate, is 38mm with a maximum heatsink length of 1,500mm.

Other technical requirements and dimensions will need to undergo a feasibility study in each case, says the company.
