摘要
介绍换热器的流量分配不均匀性的评价方法,对微通道平行流换热器进行流量分配试验,用不同评价方法对试验数据进行处理,对比6种流量分配不均匀性评价方法的优劣。结果表明,采用相对标准方差衡量流量分配的不均匀性最为合理。
The evaluation methods for the flow distribution non-uniformity of heat exchanger are introduced, the flow distribution experiment about one micro-channel heat exchanger with parallel flow is conducted. Different evaluation methods on flow distribution uniformity are used to process the experimental data,the pros and cons of six different evaluation methods are compared. Results show that the relative standard deviation method is the most reasonable.
