两种流路结构波纹翅片换热器换热与阻力特性的理论研究

摘要

本文模拟研究了两种换热流路结构的波纹翅片换热器的换热与阻力特性。模拟结果表明换热器A的换热量略大于换热器B换热量，而换热器A制冷剂侧阻力却远大于换热器B制冷剂侧阻力。综合来看，换热器B流路优于换热器A流路。因而流路形式对换热器的换热和阻力的影响很大。%The influence of the way of refrigerant flow path on heat transfer and pressure drop characteristics of her-ringbone wavy fin and tube heat exchangers were investigated by simulation. The results show that the capacity of heat exchanger A is larger than that of heat exchanger B, but the resistance on refirigerant side of heat exchanger A is greatly more than that of heat exchanger B. By comparing the comprehensive performance of two dirrerent flow paths heat exchangers, it can be found that the way of refrigerant flow path of heat exchanger B is better than that of heat exchanger A and the way of refrigerant flow path is more important to research heat transfer and pressure drop charac-teristics.
