摘　　要：对CO2-空气换热器进行了研究和试验，得出了该类型换热器的传热和阻力特性曲线以及温度场分布规律。实验发现空气经冷却后压力损失比未冷却时有5％～10％的减小，而传热因子j和阻力因子f，随换热条件的改变而基本保持不变。将实验结果与参考文献数据相比较，发现阻力因子f与参考文献基本吻合，而传热因子j有所减小。CO2-air heat exchanger was studied and tested and the heat exchanger＇ s performance curve, relationship of factor j and f ,reynolds number and the flow field distribution were got. Results show that the pressure drop is 5%- 10% lower in cooling model than no heat exchange, and there is no much change about factor j and f despite of the heat transfer condition. When compared with the reference datum, the measured factor f coincides with it very well, and factor j is slightly lower than it.
