新型高效扭曲管双壳程换热器的研制
Research and Manufacture of New Effective Double Shell Twised Tube Heat Exchanger
摘要
Abstract
The heat transfer performances of twisted tubes with different twist pitchs were compared through numerical simulation of fluid dynamics .The heat transfer performances of the twisted tube heat exchanger and baffled heat exchanger were tested and compared in laboratory .The structure design inno-vations for the double shell twisted tube heat exchanger were introduced .The successful application of in-dustrial test heat exchanger shows that the enhanced heat transfer capability of the double shell twisted tube heat exchangers was increased by 30%~40%compared with conventional baffled heat exchangers . Its benefit of energy conservation is notable .The double shell twisted tube heat exchanger can be widely used in the field of industry .关键词
