MUMBAI, India, March 13 -- Intellectual Property India has published a patent application (202621010561 A) filed by Symbiosis International, Pune, Maharashtra, on Jan. 31, for 'a double pipe heat exchanger.'
Inventor(s) include Paridhi Chhabra; Vishal Shah; Jaideep Sayaji Shinde; Shivani Trivedi; Saurabh R. Shirode; and Prof. Vikas Gulia.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The invention relates to an enhanced double-pipe heat exchanger utilizing aluminum oxide nanofluid as the working medium to improve heat transfer performance. The heat exchanger consists of a copper inner tube and a concentric galvanized iron outer tube forming an annular passage for secondary fluid flow. The nanofluid enters the heat exchanger through an inlet and exits after thermal exchange through an outlet, while the secondary fluid flows in the opposite direction to maximize temperature gradient. Heat transfer takes place across the tube wall interface, where the superior thermal conductivity of the aluminum oxide nanofluid enables enhanced convective heat transfer, improved energy exchange efficiency, and reduced thermal resistance when compared to conventional fluids such as water. The invention provides a compact, energy-efficient, and industrially scalable thermal management solution suitable for refrigeration, automotive cooling, chemical processes, and HVAC applications."
