Fanless cooling for ultrathin laptops
Ventiva in the US has launched a ion-based fanless cooling system that can handle 40W thermal requirements in ultrathin laptops.
The Ionic Cooling Engine (ICE) engine generates ions that are repelled from the emitter to create airflow without a fan. Ventiva’s ICE9 thermal management system combines the ICE technology with a software-controlled power supply to achieve the 40W thermal envelope..
The power supply is driven by system voltages and designed to be easy to integrate. It uses the pulse width modulation (PWM) that previously controlled the fan to control the system’s ICE9 devices. A thermal designer only has to connect their existing system fan control to the ICE9 devices, letting the integral ICE power supply translate PWM outputs to the voltage and current levels required to make the system blow “harder” or “softer.”
By incorporating a direct air inlet at the bottom of the laptop, an ICE9-based laptop system has a steady flow of ambient air directly into the thermal management module.
The ICE9 fanless cooling device is designed to be modular so that each component can be cooled individually. gap, laptop designs become naturally thinner, falling to less than 12mm. It can be arranged in different shapes, with each component a different length. The ICE9 engine is up to 80% smaller than a fan or blower, allowing laptop engineers to increase the battery sizes or add system functionality without changing the overall footprint dimensions of the machines.
“Our ICE technology is transforming the electronics market, enabling a new wave of silent, intelligent heat-transferring thermal management solutions, and our latest results underscore the remarkable scalability of our ICE9 solution,” said Carl Schlachte, Chairman, President and CEO, Ventiva. “Initially demonstrated within the ‘thin and light’ category of laptops at around 15W TDP, the ICE9 device now enables laptop manufacturers to extend these benefits to higher performance systems, paving the way for the launch of entire product families of silent computing products.”
Ventiva is working with select partners to productize the ICE9 thermal management suite for up to 40W TDP in 2027. The ICE9 system for up to 25W TDP is available now.
