Aavid Thermacore designs thermal management solution for telescope


aavid thermacore europe has worked with australia’s commonwealth scientific and industrial research organization (csiro) to build a thermal management solution for new high-tech radio telescope phased array feeds (paf), according to a notice on themanufacturer.com.

the paf are part of csiro’s australian square kilometer array pathfinder (askap), which will create 36 simultaneous beams to expand the field-of-view to 30 square degrees.

 

the article explained, “as a result, askap will capture radio images of the sky in more detail and faster than ever before. it will allow astronomers to answer fundamental questions about our universe, such as the nature of cosmic magnetism and the evolution and formation of galaxies.”

 

paf is hermetically sealed with 188 signal channels, including 94 in each of two polarizations, and aavid thermacore was brought in to devise a cooling solutions to beat the heat during australia’s summers in which temperatures can soar above 40°c.

 

according to a report on photonics.com, the aavid thermacore design included “heat pipe assemblies, vapor chambers, micro-channel and porous metal liquid cold plates, annealed pyrolytic graphite, enclosure heat exchangers, vacuum-brazed assemblies, and refractory metal alloys, among others.”

 

the company was recognized by csiro for its contribution to the project.

 

steve barker, project leader, csiro, who flew in from sydney, australia to present a plaque to staff at aavid thermacore europe’s ashington facility, said, “we are incredibly grateful to aavid thermacore for its support with the askap project. throughout their time working on the project, the staff at aavid thermacore continually went above and beyond to provide support and guidance to our engineers on-site in australia. their knowledge and expertise in thermal management has enabled us to progress with the project, so i am delighted to present them with a recognition award for all of their hard work.”

 

david mullen, project engineer, aavid thermacore europe, said, “csiro approached our australian distributor, jhc specialised solutions, to explore the possibility of using aavid thermacore’s technology in the askap project almost four years ago. over two years, we delivered more than 36 systems, each with a 1.2 metre diameter complex assemblies with embedded heat-pipes, thermo-electric fin-stack coolers, and heat transfer assemblies to csiro in sydney, who then integrated them into the paf receivers and dispatched them to askap engineers on-site in western australia.”
