Air Cooling

For cooling heat emitting applications and electronics, air cooling is used to achieve high heat dissipation and heat transfer. In certain cases, air cooling is preferred for its reliability and compact assembly over liquid cooling, particularly when leakage may be a concern.

Though water transfers heat better than air, air cooling remains a highly competitive, efficient and cost-effective cooling practice.


Air cooling is used in situations where size matters and cooling is critical, for instance in power electronics, semiconductors, converters, inverters, LEDs and GPUs.

Generative Air Cooling

By Diabatix
Air cooled heat sinks designed using generative technology provide additional layers of performance and adaptability. Each design is unique, precisely optimized to your heat source(s), manufacturing method, material, and dimensions, resulting in hot spot reduction.

Freeing the flow from the conventional pipe like s-shaped structure and channeling it through islands instead greatly reduces the pressure drop as well as increases flow uniformity.

This results in high temperature uniformity and heat transfer. Generative design offers a state of the art approach to air cooling design, providing usable, manufacture ready results in addition to new, valuable design insight.
  • High temperature uniformity
    The small channels have a high contact area with the air, improving the convective cooling.
  • Lightweight design
    Generative design is a form of topology optimization, meaning that a goal to use the least amount of material possible can be applied for lightweight-ing.
  • Low pressure drop
    The use of islands instead of regular fin structures result in low pressure drop, low power requirements, and a potential noise reduction.
  • Effective air flow
    The large channel carries air through to the smaller channels, which then regulate flow through a bottleneck effect to ensure even distribution.

With generative design, the role of designers and engineers is to frame the problem and define the goals, which the software interprets, and then uses to guide its way towards an optimal design option.
