摘　　要：设计一种新型高效的开放式热管真空管式太阳高温集热器,详细阐述该装置的结构及组成。通过试验的方法对开放式热管的传热性能进行分析,获得开放式热管热传导系数最佳的液体注入量;讨论分析在开放式热管中分别以去离子水和CuO纳米流体作为填充液的热效能;为开放式热管太阳集热器的工程应用提供了理论依据。At present flat plate and evacuated tubular solar collectors can only provide low-temperature heated water. The paper puts forward a new high efficiency open heat-pipe evacuated tubular solar collector, whose infra- structure and components were described in detail. The thermal performance of the solar collector was evaluated using experiment method. The optimal liquid filling ration in the heater was deserved. The thermal performance using deionized water and CuO nanofluids as filling liquid were analyzed separately. The experimental results provide theoretical foundation for the engineering applications using the solar collector.
