Experimental Analysis of Micro Channel Heat Sink with Spiral Configuration

This paper aims at the experimental analysis of micro channel heat sink with spiral configuration for measuring heat transfer characteristics. Base plate of aluminium has been used for the designing of spiral micro-channels. The cross section of channel is rectangular with sides 1mm x 0.5mm. Water has been used as the working fluid for testing purpose and final results are obtained on nano-fluids as the medium of heat transfer in the heat sink. Tests are performed by nano-fluids entering from one end and exiting from the other end. The experimental setup has been analysed for variations of thermal resistance, pressure drop and flow rate with respect to Reynolds's number. Data acquisition system for the micro-channel heat sink is designed for monitoring and processing the data obtained from the sensors at the initial and final ends of the micro-channel heat sink, including temperature sensors, pressure gauges and flow sensors. The data acquired from the sensors has been taken from self-designed data acquisition system and processed on National Instruments software Lab VIEW. The monitoring and graphical display is performed on hardware based Liquid crystal display and virtual instrument designed on NI Lab view.
