The experimental results indicate that free convection caused by the buoyancy in the heated tube with natural circulation has great influence on the heat transfer characteristics.
实验结果表明,自然循环工况下上升加热段内工质的物性变化及由浮升力引起的自由流动对对流传热特性有重要影响。
Generally forced convection circulation heating device taking gas as heat transmission medium requires high temperature uniformity. So it is very important for selection of fans and control method.
对温度均匀性要求较高的电热设备,通常采用强制循环对流的加热方式,因此风机的选型及控制对能否达到要求的温度均匀性至关重要。
