In this paper, we present the results obtained in the manufacturing and testing process of the thermal properties of nanofluid-based Coolanol-20 containing carbon nanotubes (CNTs). The presence of CNTs has improved thermal conductivity of the liquid, with a concentration of 1.0% vol CNTs showing an increase in thermal conductivity of 65%. To test the efficiency of the fluid, we have built a satellite model and a system that simulates the real working conditions of the satellite in space. Through our experiments, we have shown that Coolanol-20/CNTs has helped to improve heat exchange efficiency for components operating under harsh conditions.
