摘　　要：光伏组件在发电过程中自身温度的升高会导致发电量损失,采用被动控温是提高光伏组件发电量的有效方法之一。本文针对相变材料(PCM)热管理存在的导热性能不足的问题,提出相变材料与热管(HP)耦合的被动控温方法与模块化装置,并搭建移动测试平台开展不同气象条件下控温性能实验研究。研究结果表明,相变材料与热管耦合能进一步提升光伏板控温效果,可避免因相变材料完全融化导致的散热热阻突增问题。在此基础上,从工程口径对不同地区的典型方案开展经济性评价,资本金内部收益率变化在0.6%-4.8%之间,证明被动控温增效技术有助于提高光伏发电项目的经济性。The increase in temperature of photovoltaic modules during the power generation process can lead to a loss of power generation.Passive temperature control is one of the effective methods to increase the power generation of photovoltaic modules.This article proposes a passive temperature control method and modular device that couples phase change materials(PCM)with heat pipes(HP)to address the issue of insufficient thermal conductivity in PCM thermal management.A mobile testing platform is also built to conduct experimental research on temperature control performance under different meteorological conditions.The research results indicate that coupling phase change materials with heat pipes can further enhance the temperature control effect of photovoltaic panels and avoid the problem of sudden increase in heat dissipation resistance caused by complete melting of phase change materials.On this basis,economic evaluations were conducted on typical schemes in different regions from an engineering perspective,and the internal rate of return of capital varied between 0.6%and 4.8%,proving that passive temperature control and efficiency enhancement technology can help improve the economy of photovoltaic power generation projects.
