摘要

利用吸液芯为Ω形轴向微槽道热管在中低温余热回收领域中较高的热回收率和品质，设计与构建了一种基于Ω形微槽道热管风冷冷却的PV/T组件。测试分析了在主动冷却条件和被动冷条件下PV/T组件的热/电性能以及热风温度。试验结果表明，组件平均光电效率高于11%，平均光热效率为30%左右，平均（火用）效率高于13%，热风温度可达41℃以上，且主动冷却PV/T组件的光电、光热效率以及（火用）效率均高于被动冷却PV/T组件。与传统PV/T组件相比，该PV/T组件具有较明显的光电/热性能优势，收集的热风可用于建筑采暖、强化通风及热风干燥。

Abstract

The design and construction were based on the omega-shaped micro grooves heat pipe air cooling PV/T component by taking advantage of the heat pipe with axial omega-shaped micro grooves wick

which has higher heat recovery efficiency and quality in middle or low temperature waste heat recovery field. Under active cooling and passive cooling conditions

thermal/electrical properties and hot air temperature of the PV/T component were tested and analyzed respectively. The test results indicated that the component's average electric efficiency

average thermal efficiency

average total efficiency

average energy efficiency and hot air temperature are more than 11%

about 30%

about 60%

more than 13%

and more than 41℃. The electric efficiency

thermal efficiency and exergy efficiency of active cooling PV/T component were significantly higher than that of passive cooling PV/T component. Compared with traditional PV/T component

this PV/T component has obvious performance advantages. The collected hot air can be used for building heating

strengthening ventilation as well as hot air drying.
