摘要:

微型散热风扇尺寸和流量越来越小,常规气动测试装置不满足其性能测试要求,该文参照AMCA-210-2007标准设计开发一套微型散热风扇测试装置。装置流量测试范围为1~70 CFM,采用流量喷嘴作为标准流量计,被测风扇接口采用窗口小法兰以适应多种类型和规格的风扇,流量喷嘴和扩压段采用活动插拔式连接以方便拆装。风扇压力计算中考虑风扇出口流动局部损失,在流量喷嘴的流出系数计算中,考虑到Re数超出标准中推荐公式的计算范围,低于下限部分采用下限Re数进行计算,并在后续标定中予以修正。经标定后,该装置流量测量不确定度在1.3%以内(10%~100%流量范围),低于10%Qmax的小流量范围流量不确定度在2%以内。

Abstract: The size and blowing rate of micro-cooling fan are getting smaller and smaller, while the conventional fan aerodynamic performance testing device does not meet its requirements again. In this paper, a set of micro-cooling fan testing equipment with AMCA-210-2007 as a reference was developed. The flow range of the equipment is 1-70 CFM, and the flow nozzle is used as standard flowmeter. The connection interface for the fan being tested adopts a window flange to fit the fan measurement of various types and specifications. The flow nozzle and the expansion section are connected with movable plug and pull to facilitate assembly. In the fan pressure calculation, the local loss of the fan outlet flow is considered. In the calculation of the outflow coefficient of the flow nozzle, the lower limit Re number is used when the real Re number is below the lower limit of the formula recommended in AMCA-210-2007, and the outflow coefficient will be subsequently corrected in the later calibration. After calibration, the flow measurement uncertainty of the equipment is within 1.3% for the flow range of 10%-100%Qmax, and less than 2% for the lower flow range below 10% Qmax.
