Abstract: As a high energy-consuming industry，the energy loss reductions of communication base stations in telecom industry are attracting more attentions． Aiming at this problem，in this paper，a novel ventilation cooling system is proposed to reduce energy consumption，which combinates the chimney ventilation and the air-condition cooling． 3-D thermal-fluid field calculation is emploded to analyze the key factors affecting the ventilation． And orthogonal experiment is used to optimize the cooling structure parameters of the stations． To maximize to lower the operating temperature in the base stations，so as to reduce communication base stations operating cost．
