摘要(Abstract):

介绍了跨临界CO2汽车空调用板翅式内部换热器的设计思路,并介绍了内部换热器计算所需的换热系数经验关联式,对换热器的安全性做了分析并通过了水压实验。
A design of plate-fin heat exchanger used as internal heat exchanger is described for trans-critical CO_2 cycle.The two correlations for heat transfer coefficient were referenced.Safety analysis was carried out on the channel of the heat exchanger.Water pressure test for strength and tightness had been passed.
