Design and Development of Perforated Plate Heat Exchangers for Cooling of Gaseous Helium by Using Liquid Hydrogen (DEL) | Sponsored Project | Dr. Tapas Kumar Nandi | ISRO (On-going) |
These heat exchangers are built by stacking high thermal conductivity perforated plates, alternately arranged with low thermal conductivity insulating spacers, and bonding them by intermetallic diffusion bonding. We have successfully fabricated several heat exchangers using the existing hot press unit available in the Centre. These heat exchangers showed no leak at a maximum pressure of 15 bar under repeated thermal cycling between 77 K and 300 K. Photograph of a heat exchanger made in the laboratory by diffusion bonding is shown below.
A wave expander is an unsteady flow device which can transfer energy by pressure wave from one fluid to the other. Construction wise it has one or a set of nozzles and one or a set of expansion tubes. Hot high pressure gas enters the expansion tube and compresses the existing low pressure gas inside the tube through a shock wave. While the shock wave moves forward, an expansion wave moves in the reverse direction and cools the hot inlet gas. This cold gas can be used as a source of refrigeration. Because of the shock wave, heat is generated at the end of the expansion tube which should be removed by an external coolant. This type of device can have adiabatic efficiency comparable to conventional turboexpanders under certain operating conditions.
In this set up a two-stream counter flow heat exchanger can be tested by using helium gas. Compressed helium at 300 K is passed through the hot stream of the heat exchanger and same helium is cooled by liquid nitrogen to 80 K before it is used as cold fluid which passes through the cold fluid channel and finally return back to the helium compressor in a closed circuit.
In this setup PT-100 temperature measurement sensors can be calibrated with reference to a standard sensor. In this setup the sensors can be calibrated from 65 K to 173 K by using liquid nitrogen.
This facility was created under FIST programme of DST. Enough expertise has been developed on this unit through continuous operations over the last 14 years. In this unit samples can be heated upto a maximum of 10000C as well as subjected to a load of 5 Tonne (maximum) inside a high vacuum (10-6 mbar) chamber. This unit is useful for fabrication of compact heat exchangers by diffusion bonding. Approximate size of the sample space is 15cm x 15cm x 17cm.
