Abstract Aimed at the of reliability problem of the 3G (the third Generation) mobile
communication equipment because of high thermal dissipation, a base station is
modeled and simulated by a simulation tool of electronic cooling. Based on the analysis
to the simulation result, the configuration of the cabinet is reconstructed and the
position of different function module is reorganized. The simulation result shows that
heat dissipation efficiency and the reliability are increased.
