本文对常规管内和微通道中的CO_2汽化过程进行了研究。实现了小通道内CO2沸腾换热的实验数据库，建立了小通道内CO2汽化换热系数的预测模型。利用建立的水平流动实验数据库对该模型进行了验证，该模型涵盖了汽车空调二氧化碳蒸发器的运行工况。
In this paper, the study of the CO2vaporization in both conventional tubes as in mini-channels is presented. An experimental database of CO2boiling heat transfer in mini-channel has been realized and a predictive model of heat transfer coefficient of the CO2vaporization in the mini-channel has been developed. This model is validated using a constructed experimental database for horizontal flows and covering the operating conditions of an automotive air conditioning CO2evaporator.
