Since 2012, Koolkwic has been developing ideas for new types of cooling system. In early 2013, with the help of the WMG centre HVM Catapult’s Energy Innovation Centre, Koolkwic were able to demonstrate that this concept had huge potential for use in a range of industries including automotive and motorsport and aerospace with further potential for the beverage and facilities management industries where thermal control is a critical issue. With continuing support from the Energy Innovation Centre, early performance evaluation work on a novel cooling solution has now led to the successful creation of a European RDF funded collaborative research project aimed at delivering a fully characterised battery pack cooling solution for automotive applications.
This work has helped to highlight the potential of a novel technology which in turn is now generating enquiries for Koolkwic from globally recognised high performance motorsport, automotive and aerospace companies.
The WMG centre HVM Catapult's Energy Innovation Centre (EIC) helped Koolkwic to evaluate the performance of an early proof of concept Lithium-ion cell cooling solution over a variety of ambient conditions and electrical drive-cycles replicating the typical real-world conditions required by an automotive application. This early work was able to demonstrate that the cooling solution was suitable for cooling Lithium-ion cells within a vehicle battery pack and was able to cope with the thermal management requirements demanded of high performance lithium-ion battery systems.
Following this early work a proposal was successfully submitted for an RDF-funded research project involving WMG, Coventry University and Koolkwic to investigate the use of this technology for a fully sized battery pack cooling system. In addition to the battery pack solution outlined above, Koolkwic have also developed a range of cooling solutions for high performance applications including liquid-to-air and airto-air intercoolers, oil coolers and specialised radiators. The design of the liquid to air charge cooler heralds a novel method for cooling charged air down to very low temperatures; a reduction from 238C down to 10C has been achieved with the prototype model developed. The unit is totally scalable for most applications, is lightweight, and has a compact footprint.
Roger Wise, CTO Koolkwic said:
“Working with the WMG Energy Innovation Centre, with their unrivalled expertise and world clas facilities has, without doubt, helped us focus on delivering practical solutions for some of today’s critical thermal management problems using Koolkwic’s patented technologies”.
Koolkwic’s novel cooling technology
The Koolkwic cooling concept is based on solid-state (Peltier effect) cooling technology. Such solid state systems offer many potential benefits for a battery pack cooling solution such as versatile cooling system operation and control (the amount and location of cooling can be managed in real-time) ; the technology can be used for heating as well as cooling (very important for Lithium-ion battery pack conditioning in cold climates); no need for liquid cooling circuits within the battery pack (a major health & safety benefit); multi-device cooling systems offer improved resilience and fault tolerant operation (cooling can be targeted to specific areas e.g. a ‘weak’ or ‘failing’ cell).
When used as an intercooler solution, the Koolkwic technology offers incredible cooling performance in a small and lightweight package making it ideal for high performance applications where traditional technologies struggle to cope.
