description abstractTo improve the heat dissipation and cooling effect of the box and ensure the safe and stable operation of the gas turbine, research on the control and optimization of heat dissipation within the main box of the gas turbine has been carried out. Considering solar radiation, four evaluation indexes, namely, the percentage of the high-temperature zone, the percentage of the high-speed zone, the average field synergy angle, and the temperature inhomogeneity, are proposed to study the internal flow heat transfer characteristics of the gas turbine box, and an optimization scheme for the internal structure of the box-loaded body is proposed by using the orthogonal test method to improve the ventilation and heat dissipation performance. The results show that the percentage of high-temperature zone in the box body is 2.3%, which is mainly distributed near the junction of gas turbine and inlet worm gear; the average field synergy angle in this region is as high as 79.49 deg, and the temperature inhomogeneity reaches 0.98, which makes the heat dissipation and cooling effect poorer and is easy to form a localized high temperature; based on the above research to carry out the optimization of the box body structure, the percentage of high-temperature zone is reduced by 95.7% after optimization, and the average field synergy angle and temperature inhomogeneity are reduced to 72.88 deg and 0.57, respectively, so that the heat dissipation effect has been significantly improved.
