一种垂直鳍片增强辐射天冷方法用于散热:冷却技术比较研究的见解
A vertical fin-intensified radiative sky cool method for heat rejection: Insights from the comparative study of cooling technologies
中文简介
目前聚焦辐射天冷(RSC)的应用仅限于特定器件,且由于其能量密度低,适应性范围较窄。为更好地应对建筑级冷却需求,本研究引入了一种采用数值方法的新型垂直鳍增强辐射天冷散热器(VRSCR)。该设计协同地将 RSC 与对流冷却相结合,克服了低辐射冷却功率密度带来的限制。此外,本研究对五种冷却技术进行了全面比较,提供其应用潜力的见解和建议。所研究的技术包括被动辐射冷却建筑、水平辐射天冷散热器(HRSCR)、VRSCR、独立地源热泵系统(GSHP)以及传统空气源热泵系统(ASHP)。研究结果显示,进水口水温与环境空气温度的差异显著影响 VRSCR 和 HRSCR 的适应性。当 RSCR 将循环水冷却至环境水平时,推荐使用背绝缘 HRSCR 系统。相反,当 RSCR 在环境温度下工作时,更倾向于使用无热绝缘层的 VRSCR。VRSCR 的冷却功率为 106.6 W/m2,HRSCR 为 91.1 W/
