Ventiva has come up with a wire grid that effectively cools light emitting diodes, solid state lights and other electronic components in a way that can be considered both active and passive. A small charge is applied to some of the wires in Ventiva’s mesh, which creates ions in the localized atmosphere. The ions begin to move and push against molecules in the air, which in turn creates a breeze.
It’s passive because it doesn’t have mechanical moving parts, but active because heat gets removed by an air current generated by a component.
The new technology can remove 20 to 30 watts of heat from an LED bulb, and more heat with a larger array of wires.
