摘　　要：为保证燃气透平机组安全稳定运行,掌握主机箱体通风系统的换热机制,开展了燃气透平机组主机箱体通风散热研究。基于场协同原理,对主机箱体内部流场、温度场和关键设备的散热性能进行分析,并提出加装导流装置的优化方案。结果表明,主机箱体内高温区域体积占比达到7.6%,主要集中在燃气轮机轴部件附近,该部件为主机箱体内主要热源,外表面平均温度高达86.94℃;加装50°导流装置后,主机箱体高温区域体积占比减至5.1%,燃气轮机轴外表面平均温度降至81.98℃,散热效果得到显著提升。In order to ensure the safe and stable operation of gas turbine units,and grasp the heat transfer mechanism of the ventilation system of the mainframe housing,a study on the ventilation and heat dissipation of the main engine box of gas turbine units was carried out.Based on the principle of field synergy,the internal flow field,temperature field and heat dissipation performance of key equipments in the mainframe cabinet were analysed,and an optimized scheme for adding a flow-guiding device was proposed.The results show that the volume of the high-temperature area inside the mainframe housing is 7.6%,mainly concentrated near the gas turbine shaft component,which is the main heat source inside the mainframe housing,with an average external surface temperature of 86.94 ℃.After the installation of a 50° flow-guiding device,the volume of the high-temperature area inside the mainframe housing is reduced to 5.1%,and the average external surface temperature of the gas turbine shaft is reduced to 81.98 ℃.The heat dissipation effect is significantly improved.
