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.Keywords

A Fresnel lens is designed for redirecting the light for further use. Fresnel lens have short focal length, less volume, large acceptance and higher efficiency as compared to ordinary lenses.It is designed for area focus to achieve uniform illumination and less temperature at entrance of optical fiber bundle. The Fresnel lensis made up of polymethyl methacrylate (PMMA). It is a compilation of number of small square blocks, whereeach block is uniquely designed.Their ray trajectory is analyzed by using Trace-Pro software.Keywords

This paper describes the improved design of a daylight collector using a fresnelized acrylic dome. Surface inside the acrylic arch is framed to have a concentric and variable crystal that permits low-point light into the mirror tube and that reflects high-edge light, to receive a more constant light output through the span of the day. The prism is placed by a series of circular parallel grooves, with grooves closer the zenith of the cover having cross-areas that are unique in relation to the cross-segments of depressions closer the edges of the cover. Dome works for throughout the day in vertical position to illuminate the inside of a room by utilizing a mirror pipe having mirrored surface inside. Design of the collector improve the efficiency when compare with the conventional dome.Full Text
