Edinburgh, October 20, 2021. – The United Nations Office for Outer Space Affairs and the China Manned Space Agency have accepted In Quattro’s two-phase flow cooling system as one of nine science projects planned for the China Space Station (CSS) in 2022, a announced In Quattro. All experiences are focused on building capacity in space science and technology to achieve the Sustainable Development Goals.

The CSS opportunity was announced in May 2018 and was open to all UN Member States. The nine research projects were chosen after a careful evaluation process from a total of 42 applications from 27 countries. Italian start-up In Quattro is the only private company to be accepted for the space project.

The high-performance micro two-phase cooling system for space applications is named Baridi Sana, or “very cold” in Swahili. The project replaces ordinary liquid cooling loops with a two-phase cooling system with a non-toxic organic cooling agent.

Unlike conventional heat pipe and liquid cooling, In Quattro claims its technology can remove higher heat fluxes using less pumping energy. According to the company, the system operates with reduced power consumption due to low flow and condenses the refrigerant, thus operating with greater efficiency. The technology could help achieve efficient thermal control of satellite on-board electronics.
