Innovative Flexible Heater Solution for Satellites and Space Operation

HNu Photonics proposes the development of a self-regulating heater with properties that will revolutionize thermal management in satellites, reducing resource demands and enhancing reliability. The development of these advanced self-regulating systems will not only optimize thermal control for propellant systems but also extend their benefits to other satellite components such as batteries, mechanisms, and antennas. The successful implementation and commercialization of this technology will significantly improve the efficiency and cost-effectiveness of satellite missions, marking a substantial advancement in space thermal management. This heater material is designed to meet stringent requirements essential for functionality and durability in extreme space conditions. It features a small, thin form factor and an extremely, durable, rugged, and flexible material capable of multiple tight radius bends that can be molded or extruded into nearly any shape required. This material is highly efficient, converting approximately 99% of electrical energy into heat, and exhibits the necessary positive temperature coefficient (PTC) properties, ensuring safe and automatic temperature regulation without the need for additional control systems. Engineered to withstand vacuum, ionizing radiation, and wide thermal cycles, the heater maintains structural integrity and performance. The heater's temperature setpoint can be precisely tuned during manufacturing, meeting the required range from -5°C to 20°C, and operating with voltages between 12V and 100V DC.  Initial tests demonstrate the material's flexibility and ruggedness, including its ability to function after exposure to -80°C. For this project HNu Photonics will collaborate with the University of Hawai‘i Natural Energy Institute (HNEI) and its PakaLai Battery Test Lab, leveraging the capabilities of the university researchers and facilities to help advance the development and commercialization of robust self-regulating heater systems for satellites and space missions.
