There are three basics to creating low-noise axial fan applications: airflow path design initial fan design analysis and correction of specific acoustical responses in the physical model Each is important and contributes to the overall sound levels of the program. Figure 1. Representative flow-versus-pressure characteristic of system air path.A flow-versus-pressure … [Read more...]
A simple method to estimate heat sink air flow bypass
Introduction After selecting or designing a heat sink based upon a given air velocity orvolumetric flow rate through the fins, the thermal designer needs to determinethe total amount of flow which must be delivered in the duct or card passagecontaining the module w with heat sink. As shown in Figure 1, some of the flowwill go around or bypass the heat sink. In fact, depending … [Read more...]
