Thermal Performance of a Heat Pipe Embedded Evacuated Tube Collector in a Compound Parabolic Concentrator

This paper presents the design, development and performance evaluation of a compound parabolic concentrator for medium temperature application. In the present study Compound Parabolic Concentrator (CPC) has been used as a non-imaging solar concentrator. A single piece of evacuated tube heat pipe solar collector has been used to collect the solar radiation which is concentrated by the CPC. The condenser of the heat pipe has been directly inserted into the storage tank. The performance of the system has been evaluated for different tilt angles. Different performance parameters such as system thermal efficiency and standard power have also been evaluated in this paper.
