A theoretical model of the thermal environment in the generator cabin at the antarctic low temperature and low pressure conditions is established. The air flow heat transfer in the generator cabin and the heat transfer process of the equipment in the cabin are investigated numerically. The effects of the heat dissipation of the diesel generator and ventilation on the air temperature in the generator cabin under extreme temperature are explored. Meanwhile, the effects of heat transfer mode, device power consumption and coupled heat transfer on the temperature of the power device in the cabin are analyzed. Studies have shown that the air temperature in the cabin rises when the ambient temperature of the cabin is risen, the heat dissipation of the diesel generator is increased, the ventilation is reduced, or the power consumption of the device is increased. In addition, large air disturbances, high power consumption, and close proximity to the diesel generator can result in high power device temperature.
