Analysis and optimization of heat dissipation of gas mainframe case based on field synergy principle
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
