Fig. 4 Time history of temperature difference for steady-state analysis
after 2–3 h as shown in Fig. 4. At steady state, for the supplied heat input, the
convection coefficient was calculated [7] accordingly.
4.2 Experiments with Solid 6 Fin Based Heat Sink
From Fig. 5a, b, it has been observed that the magnitude of convection coefficient
and the base-to-ambient temperature difference increases with increase in total heat
supply for solid fin-based HS.
