摘　　要：基于CPC型太阳能集热器的发展现状,介绍了肋片型、导热油型两种CPC热管真空管集热器的结构,并对集热器进行了传热分析,得出集热器的瞬时效率方程。结果表明,导热油型CPC热管真空管集热器的效率明显高于肋片型CPC热管真空管集热器的效率,且加工工艺简单,成本相对较低。Based on the statement of the present development situation of CPC （compound parabolic concentrator ） solar energy collectors, two CPC-types heat-pipe vacuum tubular collectors are discussed, ie., the fin type and conduction oil type. Analyzing the heat transfer process of the collectors, their instantaneous effciency formulas are given. The calculation results show that the efficiency of conduction oil type CPC heat-pipe vacuum tubular collectors is much higher than that of fin type ones. Moreover, the former is superior to the latter in both process technology and cost.
