**6. Conclusions**

In present work analytical study of micro-channel heat sink has been performed at a constant power supply of 95 W using PCM slurry at φ = 0.25 and φ = 0.50 for flow rate in the range of 75 ml/min to 300 ml/min at inlet slurry temperature of 303 K. following conclusions have been drawn.

1.2% in wall temperature has been observed for higher concentration (φ = 0.5) corresponding to 0.6% decrease in wall temperature for φ = 0.25 due to higher heat transfer coefficient of highly concentrated slurry.
