摘要：
As the shell side of flow plate baffle heat exchanger scours crossly heat exchanger tubes, there are some disadvantages such as big vibration and pressure drop, and easily fouling, and low Reynolds number Re of shell side flow of rod-baffle heat exchanger when it is used as cooling oil exchanger. To overcome these disadvantages, flower baffle heat exchanger was developed, which has a new kind of support structure in shell side with different flow way from that of single-plate baffle heat exchanger. Shell side flow scours vertically heat exchanger tubes. And it has low shell side pressure drop, low noise caused by tube vibration. By contrasting experimental research of heat exchange and flow resistance between flower baffle heat exchanger and plate baffle heat exchanger, the shell side pressure drop of flower baffle heat exchanger is about 70%-80% of plate baffle heat exchanger when Re is the same. The integrated performance ratio of flower baffle heat exchanger contrasting with plate baffle heat exchanger is 110%-140%.
