| 摘 要： | 针对传统弓形折流板换热器壳侧压降大的问题,提出交错百叶折流板管壳式换热器,通过三维数值模拟,对不同周期下的交错百叶折流板管壳式换热器性能进行研究,获得壳侧流场、温度场的换热和阻力性能.结果表明:与传统弓形折流板换热器相比,交错百叶折流板管壳式换热器壳侧形成了较好的螺旋状流动,温度场分布均匀;在相同的质量流量下,交错百叶折流板管壳式换热器壳侧压降显著降低,单位压降的传热系数最高提高110.51%,综合性能大幅提高.

| Abstract: | In order to solve the problem of large pressure drop in the shell side of traditional segmental baffle heat exchanger, the shell and tube heat exchanger with staggered louver baffle was proposed. Through three-dimensional numerical simulation, the performance of shell and tube heat exchanger with staggered louver baffle under different periods was studied to obtain the heat transfer and resistance performance of shell side flow field and temperature field. The results show that compared with the traditional segmental baffle heat exchanger, the better spiral flow is formed on the shell side of shell and tube heat exchanger with staggered louver baffle, and the temperature field is evenly distributed. Under the same mass flow rate, the shell side pressure drop of the shell and tube heat exchanger with staggered louver baffle is greatly reduced. The heat transfer coefficient of unit pressure drop increases by maximum 110.51%, and its comprehensive performance is greatly improved. |
