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.
