Hi Technology Insight; We Talk To Business.

Liquid cooling start up Iceotope talks about the basics of its business;

Fluids don't always mean death for electronics, as founder Peter Hopton explains.

Iceotope has developed an efficient liquid cooling technology that allows supercomputers and data centers in the UK, and even in hot equatorial regions, to run as efficiently as those based the Arctic Circle. Iceotope's system was modeled using computational fluid dynamics, and eliminates the need for air conditioning units and fans to carry heat away. Wired.co.uk spoke to founder Peter Hopton.

HQ: Sheffield, UK

Founder: Peter Hopton

Launched: 2012

Funding: £2 million ($3.2 million) from Investment Partners of Guernsey. £6.4 million ($10.5 million) Series A funding round with Aster, OMBU and the regional growth fund.

What is your proposition to potential customers?

The company was set up with the objective of making fans and air conditioning units obsolete. Spinning fans that push air over electronics is an incredibly inefficient way of removing heat and liquid cooling has long been seen as a winning alternative. The problem has always been developing a liquid cooling system that actually works and will have big server farm operators willing to use it. I believe we've cracked this nut with Iceotope.

What problem do you solve?

IT generates heat and if this heat is not taken away, electronics will begin to bend, break, and fail. Iceotope's technology removes this heat and it does so much more effectively than traditional cooling methods. It also allows this heat to be recycled in the form of hot water, which can be fed into domestic radiators to reduce heating bills.

On a larger scale, Iceotope helps to solve the biggest problems associated with the rapid growth of the Internet. The global digital footprint is estimated to account for ten percent of energy use worldwide and data centers represent a big part of this. Our technology can halve the energy use of these facilities and therefore has the potential to have a big impact on global energy use as a whole.

How do you plan to make money?

Through shipping equipment, but ultimately we intend to create a product ecosystem around our liquid cooling technology by opening the technology up to other vendors.

Where did you get the idea for the business?

In 2005 I was studying the history of liquid cooling used in old equipment in the 70's and 80's such as the Cray 2 supercomputer. I was interested in making a modern version that met the needs of a modern server user. Immersion cooling has had its issues in the past, whether using lots of energy to pump primary coolant or by degradation during the boiling of coolant in a phase change system. During our experimentation we discovered the convective cell used in Iceotope's technology and filed patents—this eliminates the need for pumping primary coolant and solves problems previously associated with phase change.

What's the biggest misconception about your business?

Most of the liquids people encounter on a daily basis don't mix well with electronics. Everyone's spilled coffee on their laptop or dropped their smartphone down the toilet, probably to disastrous effect.

People can get nervous at the thought of mixing electronics and liquids but fortunately the substance we use doesn't conduct electricity so it's completely safe to do so. I've dunked my phone in the stuff countless times and it still works perfectly.

Can you express in some tangible terms how the business has developed?

18 months ago, all we had was the proprietary technology. Now Iceotope has a commercial product and multiple customers using it daily. We've also had a significant financial boost following the closure of our £6.4m funding round.

What has been the most challenging time for the company?

In late 2011/early 2012, when the company was in flux and we were faced with the mammoth task of making Iceotope's technology into a product. There were lots of new faces in the team (particularly at the management level) and long hours to work, so it's hardly surprising that this was a difficult period.

How did you overcome that?

Hard work and not much sleep. As soon as the new team started to bond, that really helped matters too.

What is the best piece of advice anyone has ever given you?

"Ain't no presentation, without caffeination". I think this stuck with me because it was so well delivered at the time. It's especially true if you've just got off the plane in another time zone and are expected to take a meeting within the hour.

Hi Achieve "Cooling Efficiency.!"

Hi Achieve " Altering surface textures in 'counter intuitive manner' may lead to cooling efficiency gains."

Uncovering the physical secrets underlying surface phenomena may increase cooling efficiency for a wide range of applications, according to MIT and Boston University researchers

WASHINGTON, D.C. Nov. 12, 2013 -- Researchers across the globe are racing to find ways to improve the cooling of hot surfaces -- for technologies ranging from small handheld electronics all the way to industrial-sized applications such as nuclear power plants.

By zeroing in on the physics at play underlying surface phenomena, a team of Massachusetts Institute of Technology (MIT) and Boston University researchers made a significant breakthrough. Although somewhat counter-intuitive, they discovered that by creating sparsely packed textures on surfaces rather than densely packed ones, they were able to hold droplets in place and enable cooling.

Their findings, described in Applied Physics Letters, which is produced by AIP Publishing, have the potential to enabling cooling efficiency gains in a wide variety of applications.

Worldwide, nearly 86 percent of our energy is currently derived from steam cycles. "If we're able to improve this efficiency by even 1 percent and deploy it to all of the power plants, it could have a significant impact," explains Kripa K. Varanasi, Doherty Chair in Ocean Utilization, as well as an associate professor of mechanical engineering at MIT.

Varanasi's lab is known for tailoring or modifying surfaces to significantly improve efficiency. One of their recent creations was a slippery surface coating, which is now being commercialized by a spinoff called Liqui Glide. They're commercializing a container liner that makes toothpaste and other difficult-to-remove products, such as ketchup, slide right out of their tubes and containers -- greatly reducing waste.

For this particular study, the goal was the exact opposite of creating slippery surfaces. The researchers wanted to make liquid come into direct contact with hot surfaces so cooling could occur. They began by exploring the physics of surface phenomena, because whether focusing on mass transfer, momentum transfer, energy transfer, or charge transfer, the commonality is that the transfer occurs on a surface.

Water Droplets (1 of 2)

Image Caption: These are micro graphs showing water droplets landing on specially designed silicon surfaces (top images) at different temperatures. At higher temperatures, the droplets begin to exhibit a new behavior: instead of boiling, they bounce on a layer of vapor, never really wetting and cooling the surface. At 400 C, the droplet continues to boil only on the surface that combines micro-scale posts with a coating of nano scale particles (last column). These results demonstrate that this micro nano surface can be effectively cooled even at high temperatures.

"Vapor films are created beneath the droplets, which is a critical problem in boiling. Once the vapor films start forming, they act as a barrier to heat transfer because vapor has a lower thermal conductivity than liquid," Varanasi says.

In boiling, ideally the liquid will make contact with the solid. But this phenomenon has a certain threshold known as a "critical heat flux" -- once it's reached, a catastrophic event may occur. For example, in the absence of cooling fluid during an emergency situation in a nuclear power plant, a nuclear fuel rod's surface can become very hot. Pouring water on it to attempt to cool it results in the formation of a vapor film that actually interferes with cooling. As a result, droplets float on the hot surface, which is known as the "Leiden-frost effect."

To overcome the vapor film issue, Varanasi and colleagues textured surfaces using sparsely packed micron-scale structures coated with nano particles to create a capillary attraction effect to hold droplets in place.

"Vapor that forms as the evaporation of the droplet is able to escape through the surface texture," Varanasi explains. "Interestingly, there are two simultaneous competing forces occurring in this situation. As the vapor forms, it exerts an upward force on these droplets. And the texture pulls on the droplet with capillary attraction. This allows the liquid to come into contact with the surface and cool it."

They can engineer similar structures using a variety of materials and techniques, according to Varanasi. Right now, the team's focus is on exploring the energy, water and agriculture nexus because it's all interrelated. "We're hoping in our own humble way -- since many phenomena occur upon surfaces -- to improve them and enable big efficiency in this nexus," he says.

Key markets that may benefit from greater cooling efficiency gains include, but aren't limited to, nuclear power plants, semiconductors and electronics, oil and gas, fire suppression, desalinization, and metallurgy.

Image Caption: These images show droplets being deposited on silicon surfaces that are smooth (top) and that have micro-scale silicon posts placed either close together (middle) or relatively far apart (bottom). At 270ºC (left), droplets land and boil on all three surfaces—behavior conducive to efficient cooling. But at 300ºC, they boil only on the surface with the widely spaced posts. On the other surfaces, they bounce on a layer of vapor.
