研发一种双管程热交换器(液/液),以强化传热技术为基础，从换热温度、流体流速、蒸发量和最小换热温差4个方面进行协同优化设计。通过相变优化、驻点优化技术，该换热器换热能力可提高30%,同时增强了抗堵塞和耐腐蚀能力。

Based on enhanced heat transfer technology,a double-tube heat exchanger (liquid/liquid) was developed.The optimal design was carried out from four aspects: heat transfer temperature,fluid velocity,evaporation capacity and minimum temperature difference.Through the technology of phase change optimization and stagnation point optimization,the heat transfer capacity of the heat exchanger can be increased by 30%,and the anti-clogging and anti-corrosion ability can be enhanced simultaneously.
