MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202631095835 A) filed by National Institute Of Technology Durgapur on August 07, 2026, for Quasi-Immersion Feedback-Controlled Active Cooling System.
Inventors include Saha, Subhadeep; Thakur, Manish; and Kumar, Ratnesh.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: A thermal management system (100) for a wire arc additive manufacturing apparatus is disclosed. The system (100) includes a cooling bath chamber (102) configured to contain a liquid cooling medium and positioned adjacent to a deposition zone such that a deposited bead is maintained at a predetermined bead-to-bath distance above a surface of liquid cooling medium while a molten pool remains out of contact with liquid cooling medium. The system (100) includes a cooling medium reservoir (104) in fluid communication with cooling bath chamber (102), a cooling medium circulation system (110), a bead-to-bath gap regulator system (106) to regulate a level of liquid cooling medium to maintain predetermined bead-to-bath distance, a heat exchanger system (112), temperature sensing devices (108), and a controller (114). The system (100) continuously extracts heat from deposited component and substrate during deposition to reduce heat accumulation while maintaining arc stability, metallurgical fusion, and process consistency.
