摘　　要：以空气为冷却介质,对镀碳纳米管铜岐片微通道冷却器进行了气冷散热性能实验研究。通过测量微冷却器出入口温度、底面温度与压降,研究了镀碳纳米管铜岐片微冷却器的散热性能。对镀碳纳米管的铜岐片和硅岐片微冷却器,通过实验比较得到,两种材料微冷却器的热阻在低热流密度时,温度变化梯度较大,随着热流密度的提高,热阻变化趋于稳定,并且镀碳纳米管的铜岐片微冷却器散热性优于硅岐片材料微冷却器。In this paper,the heat transfer performance of gas flow in copper channels coated with carbon nanotubes of micro coolers is studied. By measuring the temperature and pressure at inlet and outlet of the micro cooler and the average temperature at the micro cooler bottom, the heat transfer performance of the copper based CNTs coated micro cooler is researched. The thermal resistance of copper and silicon based CNTs coated micro coolers are compared. It is shown that the copper based CNTs coated micro cooler has better thermal dissipation capacity than that of the Silicon based CNTs coated micro cooler.
