新型CPC热管式真空管集热器设计与性能分析

摘要

Based on present situation of the compound parabolic concentrator (CPC)type heat collec-tors,a novel CPC heat pipe type evacuated tubular heat collector has been designed,the structure de-sign and calculation process of light-gathering surface and receiver for said novel heat collector being presented. After analysis of heat collection in the novel CPC heat pipe type evacuated tubular heat col-lector,the instantaneous efficiency formula of the said novel heat collector has been obtained. The per-formance comparison between the novel heat collector and the traditional fins type tubular heat collec-tor shows that the novel heat collector has remarkably high efficiency, simple fabricating process, and lower cost.%基于复合抛物面集热器(CPC)型集热器的发展现状,设计出新型CPC热管式真空管集热器.介绍了该集热器的聚光面和接收器的结构设计及计算过程,在对新型CPC热管式真空管集热器进行集热分析后,得出其瞬时效率方程.与传统肋片型CPC热管式真空管集热器相比,新型CPC热管式真空管集热器效率高,加工工艺简单,成本较低.
