Manufacturing enhanced heat transfer surfaces on commercial heat exchangers

Heat transfer is highly important for many technologies, including electronics, refrigerators, energy production and data centres. Increasing the rate of heat transfer from a surface to its surroundings would improve all applications that lose energy through wasted heat.

Andrew will develop a novel method for manufacturing enhanced heat transfer surfaces on heat exchangers at a commercial scale. This will involve developing a method of producing microchannels on the internal surfaces of commercial heat exchangers. Current technology developed at Oxford nanoSystems has increased heat transfer efficiency by 524% and Andrew hopes this new technique will build upon this improvement. Efforts to create microchannels on industrial heat exchangers have not been successful to date due to time consuming, expensive processes and have been limited to flat structures. His new method will allow the creation of microchannels on any type of surface, and will allow heat exchangers to be smaller, lower in cost and more efficient, saving energy and resources.

Andrew Anderson graduated from Heriot-Watt University in 2015 with a Masters in Chemistry with Nanotechnology, and joined Oxford nanoSystems afterwards, where he now works as an Industrial Process Chemist. Andrew’s role involves developing nanocoatings to improve heat transfer for power generation and cooling.
