通过三维CFD数值模拟软件ANSYS-CFX模拟优化4种波纹板式换热器,计算区域为1-1程的三流道板式换热器包括进出口段和倒流区段.数值计算结果表明,φ=60°的新型板式换热器比φ=60.的人字形板式换热器的努塞尔数高约15％,摩擦阻力系数低约10％,综合性能提高约20％,其中波纹比例系数为3∶1的板片的综合性能最优.%Four kinds of corrugated plate heat exchangers (PHE) were simulated applying three-dimensional CFD software-ANSYS-CFX. Three-flows plate heat exchanger whose computational domain is 1-1 process, includes import and export segment and reflux section. The results from numerical simulations show that Nusselt number of the working fluid in new-type PHE with Φ=60°,compared with the chevron-type one, is increased by 15% , the flow resistance is decreased by 10% , and the performance evaluation criteria is increased by 20%. The plate with corrugation ratio of 3 : 1 is better than any other type.
