Today’s electronic devices require more from active thermal management systems than current solutions can provide. System designers need better airflow solutions to solve complex thermal issues created by industry trends toward smaller, faster, more functional devices with higher component densities and processing power. At the same time, consumers want the comfort of high-performance devices that are lightweight, silent and vibration free.
Ionic Cooling Technology
Ventiva’s ionic cooling technology generates the movement of air particles without any moving parts, noise, or vibration. It provides up to 100W Thermal Design Power (TDP), making it ideal for lightweight, ultra-compact, vibration-free, and utterly silent electronic devices. If you’re looking for a paradigm shift in thermal management, our ionic cooling technology is the answer!
Ventiva technology is based on principles of electrohydrodynamic (EHD) flow, a fascinating science that intersects physics, engineering and fluid dynamics, to move ionized air molecules within an electric field.
Take Thermal Management to the Next Level
Ventiva ionic cooling technology is configurable and scalable for a wide range of applications, from laptop computers to handheld electronics and other electronic devices. It solves difficult thermal challenges with ultra-compact solutions that enable air movement in the tightest spaces, where traditional axial fans don’t fit.
Ventiva’s ionic cooling devices integrate easily into standard electronic assembly workflows with sizes that can be as small as 1/3 of the blowers they are replacing.
Frequently Asked Questions
What is Ventiva’s ionic cooling technology?
Our ionic cooling technology is based on principles of electrohydrodynamic (EHD) flow, a fascinating science that intersects physics, engineering and fluid dynamics, to move ionized air molecules within an electric field. It moves air in a unique way, without moving parts, acoustic noise, or vibration.
How does Ventiva technology work?
Our ionic cooling technology harnesses the power of a minuscule plasma field to move air particles, delivering a potent “solid-state” cooling wind:
- An electric field is created between two small electrodes, a high-voltage thin wire called the emitter, and a low-voltage or grounded electrode called the collector. A high voltage but very low current is applied to the emitter, creating a strong electric field that strips electrons from molecules of nitrogen, oxygen, argon (and other trace gases) in the air, creating ions.
- The resulting free electrons flow toward the positively biased emitter, while the positively biased ions are repelled from it and attracted by the grounded or low-voltage collector.
- A plasma field exists in the gap between the emitter and the collector and consists of the ionization zone and the ion drift zone. The ionization zone is very small, just a few microns in width, and is located next to the emitter.
- As positively charged ions move toward the collector, they enter the ion drift zone where they collide with neutral air molecules. These collisions impart momentum to the neutral air molecules, causing them to move toward the collector. The result is an avalanche of air molecules, in motion toward the collector.
- When this swarm of neutral and positively charged ions reach the collector, the positively charged ions pick-up electrons at the collector. These are the electrons that were stripped from the ions; they flow in the opposite direction of the current, through the power supply to the collector. This results in the outflow of primarily neutrally charged air molecules.
Is Ventiva technology similar to the technology used in Dyson “bladeless” fans?
No. Dyson “bladeless” fans use the principle of entrainment (utilizing Bernoulli’s principle) to enhance the airflow generated by a traditional, rotating blower mechanism hidden in the base of the fan. Our ionic cooling technology uses electrohydrodynamic airflow to create a truly fan-less device that generates movement of air with no mechanical parts, acoustic noise, or vibrations.
What is Ventiva’s thermal management subsystem?
Our thermal management subsystem, which is based on our patented ionic cooling technology, enables optimal performance in electronics devices—without any mechanical parts, acoustic noise, or vibration. It uses intelligent software control to continuously monitor its operation and can adaptively deliver more or less airflow as an electronic system requires. Combining advanced monitoring and algorithms, the solution’s real-time software can be combined with overall system performance monitoring to provide a robust device-wide thermal solution that is thin, silent, and totally cool.
What applications can use Ventiva technology?
Our ionic cooling technology provides high-value size and acoustic benefits for a wide range of electronic applications including notebooks and laptops, tablets, wearable devices, and AR and VR headsets.
How silent is Ventiva technology?
Our technology has been tested in anechoic chambers, showing less than 15 dBa sound pressure. This is an imperceptible level that is barely above the background noise level in an anechoic chamber.
How does Ventiva technology help laptops get thinner?
Unlike traditional blowers which are “bottom-in / side-out” air flow devices, our ionic cooling solution does not need an air gap to draw in air; it is a more space-efficient “side-in / side-out” device. This allows for a lower internal height for a laptop or tablet, of up to 2mm, which enables thinner and more elegant product designs.
How easy is it to replace a Ventiva device in the field?
It’s very easy! Remove two Philips head screws on either side of the ionic cooling device, replace it with a new device, and then replace the screws. No special cables or connectors are required.
Does Ventiva technology compete with AirJet by Frore Systems?
No. Our patented ionic cooling technology leverages EHD airflow instead of utilizing mechanical, moving parts (vibrating membranes), which means we are competing with the traditional fans that have been used since the early days of portable computers.
Is Ventiva technology “green”?
Yes, our ionic cooling solution is green and fully recyclable. In addition, we only source readily available electronic components.
How does Ventiva technology handle dust?
Dust is a fact of life, and no electronic device is completely immune to its effects. For example, any air inlet obstructed by dust halts the airflow in an electronic system which reduces or even eliminates its cooling capability.
Our ionic cooling solution uses intelligent software control to act as an advanced air quality detector. It is able to dynamically respond to the device environment, enabling it to identify and combat dust and airborne contaminants through a product’s lifespan to prevent overheating and system degradation.
Does Ventiva technology generate ozone?
Like many products in use today (e.g., laser printers, vacuum cleaners, photocopier machines, kitchen blenders, etc.), our ionic cooling solutions generate a small amount of ozone. This ozone is a by-product of the cooling process and is only generated when the device is in use.
We have developed effective and efficient catalytic decomposition techniques to speed the conversion of ozone back into oxygen, before the air is exhausted from a device that is being cooled, so that the device can be fully compliant with rigorous indoor air quality standards.
Does Ventiva technology vibrate?
No. Our ionic cooling solutions enable optimal performance in electronics devices—without any mechanical parts, acoustic noise, or vibrations.
Do ionic wind devices (like Ventiva’s solutions) degrade over time?
While it is possible for the electrodes in these devices to become less efficient over time, we have greatly mitigated this problem with our ionic cooling technology.
Our thermal management subsystem uses intelligent software control, which continuously monitors for system issues, with innovative materials to give our patented air-cooling solution the longevity needed for modern electronic products.
