Abstract：For coal mine outdoor double intelligent cabinet is easy to have high temperature breakdown prob-lems and even explode in operation,based on the computational fluid mechanics,using Fluent software analysis was made.According to the coal mine outdoor double layer structure and the working conditions etc,the finite element model was set up,and the boundary conditions were set.By orthogonal experiment,a simulation scheme was designed,the effect factors of temperature inside cabinet (exhaust air fan Q,shutter row number N and intelligent component layout C)were analyzed.It was concluded that the factors’influence on cabinet of significance was as follows:Q >N >C.The optimal design scheme was selected to make that the highest tem-perature of the cabinet was 50 ℃ ,thus meeting the requirement of temperature control of State Grid.The error between the numerical simulation and experimental results was 4.2%,which verified the correctness of the finite element simulation and provided a reference for design and analysis of high temperature performance out-door double intelligent cabinet.
