摘要

本文揭示了自然对流热损失和强制对流热损失的变化对黑镍铬涂层抛物面盘集热器原型性能的影响。一般来说,集中式太阳能集热器比平板集热器和抛物面槽集热器效率高。因此在水加热应用中可以达到较高的效率。太阳能抛物面盘集热器的设计是在焦点处由铜组成的锥形锥形螺旋盘状接收器。该原型机在2010年4月和5月进行了性能评估。

Experimental analysis of effect of variation of convection heat losses on performance of parabolic dish collector with nickel chrome coated receiver
This paper reveals effect of variation of natural and forced convection heat losses on performance of prototype parabolic dish collector with black nickel chrome coated receiver. In general, concentrated solar collectors have high efficiency as compared to flat plate and parabolic trough type solar collectors. Therefore for water heating application high efficiency can be achieved. Design of solar parabolic dish collector consists of truncated cone shaped helical coiled receiver made up of copper at focal point. This prototype was evaluated for its performance during month of April and May 2010.
