Natural Convection Cooling

Natural convection is a reliable, low noise, low vibration form of air cooling, relying on buoyancy to drive air flow instead of a fan or pump. Like conduction, since natural convection doesn't rely on a mechanical system to drive flow, its size differs than that of forced air and liquid cold components, and can be more compact.

A popular choice to cool consumer electronics and telecommunication equipment, natural convection cooling components operate best in outdoor settings.


Natural convection cooling is used in situations where reliability, noise and size are critical. For instance in cell phones, GPUs, semiconductors, telecommunication equipment and LEDs.

Generative natural convection cooling

By Diabatix
Natural convection cooled heat sinks designed using generative technology usher in 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 elimination.

Generative design offers a state of the art approach to natural convection cooling design, providing usable, manufacture ready results in addition to new, valuable design insight.
  • High temperature uniformity
    The unique shape creates air pockets and channels, improving overall temperature uniformity.
  • Compact Size
    The lack of a fan or pump reduces the size of the system, while also increasing reliability.
  • High heat transfer
    The pockets have a high contact area with the air, resulting in very high heat transfer.
  • Heat distribution control
    Specifically designed around your heat source(s), heat distribution can be precisely controlled.

See our software in action

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.
