摘要
建立了炭加热烟草加热器结构的几何模型,利用COMSOL软件仿真分析了热回收结构、入口流量对加热器传热性能的影响,并且搭建了传热性能测试平台验证了仿真的准确性。仿真分析结果表明:通过调整入口流量和不采用热回收机构能够提高加热器的传热性能。当没有热回收结构时,随着入口流量的增加,加热器温升速率提高了29%;当保持入口流量一定时,没有热回收结构的加热器传热性能优于装有热回收结构的加热器。
The geometry of the structure of the carbon-heated tobacco heater is described.The influence of the heat recovery structure and inlet flow rate on the heat transfer performance of the heater is simulated and analyzed by COMSOL.A heat transfer performance testing platform has been built to verify the accuracy of the simulation.The results of the simulation demonstrated that the heat transfer performance of the heater can be improved by adjusting the inlet flow rate and without the assistance of the heat recovery mechanism.If no heat recovery structure exists,as the inlet flow rate increases,the rising rate of the heater temperature increases by 29%.When a constant inlet flow rate was applied,the heat transfer performance of the heater without heat recovery structure is better than the device with heat recovery structure.
