摘要
加热器是热油系统中控制温度、调节热能的关键组成部分。加热器中存在一个空心管结构,其不起加热作用,但能降低加热过程中加热器的表面温度。为了研究空心管在加热过程中如何影响系统的温度场特性,分别建立了带有空心管和无空心管的加热器,使用Ansys Fluent软件进行热流耦合分析。结果表明,空心管对管道中热油的流动状态有着显著的影响,其能迫使热油以较高速度流经加热器表面,使得加热器表面温度显著降低。
Heater is the core component used in hot oil systems to control temperature and regulate thermal energy.Inside the heater,there is a hollow tube structure that,although not involved in the heating process itself,can effectively reduce the surface temperature of the heater during the heating process.In order to investigate the specific influence of hollow tubes on the temperature field characteristics of the system during heating,this study constructed heater models with and without hollow tubes,and conducted thermal flow coupling analysis using Ansys Fluent software.The analysis results show that the hollow tube has a significant impact on the flow state of hot oil inside the pipeline,which can promote the hot oil to pass through the surface of the heater at a higher flow rate,thereby significantly reducing the surface temperature of the heater.
