In its continuing
bid to transfer technologies to industry, the Indian Space Research
Organisation (ISRO) has successfully commercialised the technology
for producing sophisticated heat pipes. Besides technical support,
it also provided financial assistance to the private Indian firm
M/s. Avasarala Group, Bangalore for the manufacture of these pipes,
used in satellites.
The axially grooved
aluminium ammonia heat pipes quickly transfer heat from one zone
of the satellite to another. This helps in evenly distributing
temperature on all zones of the satellite equipment panels, despite
the heat generated by some of the instruments on the equipment
bay. Specifically these heat pipes are useful in high-power communication
satellites in controlling the temperature exuded by the on-board
transponders and related electronic systems.
The ISRO has been
encouraging private entrepreneurs to take up production and testing
of space hardwares for its own use. Earlier, ISRO transferred
to the public sector Bharat Electronics Ltd. technologies for
producing a number of high precision space qualified components.
These include Invar Filters for use in communication transponders
and c-band and ku-band receivers using microwave integrated circuits.
It had also transferred the technology to produce light weight
polyurethane artificial limb popularly known as the Jaipur leg
to the industry .
