推荐新一代换热设备——空心环管壳式换热器华南理工大学研制的空心环管壳式换热器，以其流体阻力损失小、传热效率高的性能优势，而成为管壳式换热器的换代设备．空心环管壳式换热器与双弓碟杯折流板（或单弓折流板）管壳式换热器相比，总传热系数提高５０％（或９０％）... Recommended a new generation of heat exchange equipment - Hollow shell tube heat exchanger hollow tube shell and tube heat exchanger developed by South China University of Technology, with its fluid resistance loss, heat transfer efficiency, high performance advantages, and become the shell and tube Heat exchanger replacement equipment. Hollow-ring shell and tube heat exchangers increase the total heat transfer coefficient by 50% (or 90%) compared with double-bowed cup baffles (or single bow baffles).
