A private Indian company M/s Avasarala Group, Bangalore, has successfully fabricated Heat Pipes for use in ISRO satellites. The first batch of heat pipeswere delivered by Shri A Mangapathi Rao, Chairman of the Avasarala Group of Companies to Dr P S Goel, Director, ISRO Satellite Centre at a simple functionon December 30, 2002.

The technical and financial assistance for producing these sophisticated heat pipes was provided by ISRO, as part of its initiative to encourage and develop vendors for production and testing of space hardware for ISRO's use.

The Axially Grooved Aluminium Ammonia Heat Pipes are used in satellites to quickly transport heat from one zone of the satellite to another. Thus they help in equalizing the temperature on all zones of the satellite equipment panels inspite of the heat generated by some of the instruments on the equipment bay. Specifically, these heat pipes are used in high power communication satellites for controlling the temperature of transponders and the related electronic systems.
