    • An electronics component cabinet cover test device includes a housing that defines a test apparatus provided with first and second openings. A cover member is mounted to one of the openings, and an air moving device is arranged in the test apparatus. The air moving device includes an air inlet and an air outlet and generates airflow within the test apparatus. A sensor capable of measuring a characteristic of the airflow is mounted within the test apparatus. An airflow impedance device mounted to the inlet or the outlet of the air moving device. The airflow impedance device is configured to simulate an airflow obstruction. A controller establishes a flow rate of air from the air moving device and receives airflow data corresponding to the characteristic of the airflow from the sensor to determine one of an acoustical performance characteristic and a thermal performance characteristic of the cover member.
    • 电子部件柜盖测试装置包括限定具有第一和第二开口的测试装置的壳体。 一个盖构件安装在一个开口上,并且空气移动装置设置在测试装置中。 空气移动装置包括空气入口和空气出口,并在测试装置内产生气流。 能够测量气流特性的传感器安装在测试装置内。 安装在空气移动装置的入口或出口的气流阻抗装置。 气流阻抗装置被配置为模拟气流阻塞。 控制器建立来自空气移动装置的空气流量,并接收与来自传感器的气流特性对应的气流数据,以确定盖构件的声学性能特性和热性能特性之一。
