基于无因次参数的冷却风扇匹配设计

Matching of Cooling Fans Based on Dimensionless Parameters

摘要: 介绍了冷却风扇的性能参数及无因次性能曲线的性质，分析了风扇匹配设计选型流程，并给出了应用实例。应用无因次性能曲线，对风扇进行匹配和筛选，既能检验定型产品的匹配性能，也能大大减少新产品设计中设计和试验工作量，节约成本，提高效率。

Abstract: This paper introduces the performance parameters of cooling fans and the properties of dimen-sionless performance curves, analyzes the fan matching design and selection process, and gives an application example. Applying dimensionless performance curve to match and screen fans can not only test the matching performance of the finalized products, but also greatly reduce the design and test workload in new product design, save costs and improve efficiency.
