Abstract
The integrated pipe gallery body is located underground and is a closed structure. Due to the poor air circulation in the power cabin, in the absence of ventilation, the large amount of heat radiated from the cable will cause the ambient temperature in the cabin to rise sharply. So, we need eliminate the high-temperature air gathering area, timely eliminate the heat dissipation of the cable, ensure the safe and efficient operation of the power cabin, and provide a good maintenance environment for the maintenance personnel. This paper takes the power cabin of an underground integrated pipe gallery in Shenyang as the research object, basing on the study of the structural characteristics of the powerhouse of the pipe gallery, determining typical conditions in numerical simulations in combination with local climatic conditions in Shenyang, uses The Fluent simulation software to study the ventilation and heat dissipation of the power cabin.
