摘要 为提高自旋式换热器的换热效果,研究影响换热器换热效率的主要因素,提高其换热效率,基于有限元技术,采用CFD软件对影响自旋式换热器效率的因素:扭转角、自旋片组数、内径,基于温度场环境下分别进行模拟分析,结果表明:自旋式换热器在工作时,由中心区域的流体流动产生的带动作用和横向流层的湍流前进方式,以及合适的自旋片组数带来换热面积的增大等因素,使得自旋式换热器在扭转角为90°、自旋片组数为4组、内径为60mm时,自旋式换热器换热效果最佳。本文所做的这些工作,可以为同类换热器的换热效率优化研究提供一定的参考价值。通过对自旋式换热器换热效率影响因素的优化研究,有助于提高换热效率,对节能、降耗和环保具有重要意义。 In order to improve the spin heat exchanger heat transfer effect,study the main factors influencing the heat exchanger in heat efficiency,improve its in thermal efficiency,based on the finite element technology,using CFD software on the influencing factors of spin heat exchanger efficiency:torsion Angle,spin slice group number,diameter,three factors affecting environment based on temperature field simulation analysis respectively,the results show that:Spin heat exchanger on the job,by the central region of the leading role of fluid flow and transverse flow layer turbulence way forward,and the appropriate number of sets of spin slice with the increase of heat exchange area and other factors,makes the spin heat exchanger in torsion Angle is 90°,spin slice group number 4,inner diameter of 60 mm,spin heat exchanger heat transfer effect is best.The work in this paper can provide some reference value for the simulation and optimization of heat transfer efficiency of similar heat exchangers.By optimizing the factors affecting the heat transfer efficiency of spin heat exchanger,it is helpful to improve the heat transfer efficiency and is of great significance to energy saving,consumption reduction and environmental protection.
