基于火积耗散及火积耗散热阻极值定律推导出立式集热板太阳能热气流发电系统的火积耗散率表达式，并对系统的传热性能进行分析.结果表明：立式集热板太阳能热气流发电系统的烟囱尺寸是影响系统传热性能的主要因素，但是烟囱的高度和宽度受高层建筑的高度及窗户间距的限制，因此烟囱厚度成为系统火积耗散热阻的主要影响因素；在烟囱高度和宽度不变的条件下，厚度取0．9598 m 时系统火积耗散热阻最小，系统性能最优.

On the basis of the principle of entransy dissipation and the principle of minimum thermal resist-ance in heat transfer theory,the expression of entransy dissipation rate of the solar chimney power plant system with vertical collectors was derived and the heat transfer performance of this system was analyzed. The results show that,the structure dimensions of the chimney are the main factors affecting the perform-ance of the solar chimney power plant system with vertical collectors.However,the height and width of the solar chimney are limited by the height and space between the windows of high buildings,thus the thick-ness of the solar chimney is the foremost factor to decrease the entransy dissipation of the solar power plant system.Under conditions with constant chimney height and width,the thermal resistance of entransy dissipation of the solar system reached the minimum when the solar chimney thickness was 0.959 8 m,indi-cating the performance of the system achieved the optimum.
