摘要

本研究在以往现场实验的基础上,对具有内置波纹通道的超薄导电吸热器进行了理论研究。对波纹通道的流动和传热特性进行了模拟,以确定影响光伏/热(PV/T)系统效率的因素。讨论了波纹数、波纹面积和流道宽度等结构参数对出水温度和集热性能的影响,为混合光伏发电系统的结构优化设计提供支持。仿真结果与实验结果基本一致。结果表明,进水速度的增加导致出水温度的降低。研究发现,波纹面积和流道宽度对PV/T混合集电板的出口温度有影响。当吸收器板的流道宽度从4减小时 mm至3 mm,获得的出口温度在298和302之间 K、 热量收集范围为16.2-51.4 兆焦耳/小时。这导致收集的热量增加了18.6%。

Numerical Study on the Optimization Design of Photovoltaic/Thermal (PV/T) Collector with Internal Corrugated Channels
This study presents a theoretical study on the super thin and conductive thermal absorber with built-in corrugated channels on the basis of previous field experiments. The flow and heat transfer characteristics of the corrugated channels are simulated to identify the factors affecting photovoltaic/thermal (PV/T) system efficiency. The influences of the structural parameters such as the corrugation number, the corrugation area, and the flow channel width on the water outlet temperature and heat collection are discussed in order to support the structural optimization design of the hybrid PV/T system. The simulation results were validated to be in good agreement with experimental results. The results indicate that increasing inlet water velocity leads to a decrease in the outlet temperature. It was found that the corrugation area and the flow channel width have impacts on the outlet temperature of the hybrid PV/T collector panel. When the flow channel width of the absorber plate is reduced from 4 mm to 3 mm, the outlet temperature attained is between 298 and 302 K, and the heat collection is in the range of 16.2–51.4 MJ/h. This led to an increase in the amount of heat collected by 18.6%.
