对蒸发式冷却器传热传质试验结果的数据处理进行了讨论，重点是它的容积散质系数以及工艺水到水膜的传热系数．介绍了试验台和各测试仪表，给出了对两个试件的测试结果，整理了βｘｖ和Ｋ的变化规律，并与计算结果作了分析对比 The data processing of the heat and mass transfer test results of the evaporative cooler is discussed, with emphasis on its bulk-to-bulk ratio and heat transfer coefficient from process water to water film. The test bench and test instruments are introduced. The test results of two test pieces are given, and the variation rules of βxv and K are summarized. The results are compared with the calculation results
