Description

technical field

[0001] The invention relates to a vibration induction device for strengthening heat exchange of an elastic tube bundle heat exchanger. Background technique

[0002] Shell-and-tube heat exchangers are widely used in energy, power, petrochemical and other industrial fields. The enhanced heat transfer technology of heat exchangers is of great significance to energy saving and consumption reduction. Among them, passive enhanced heat transfer technology is an important research direction at present because it does not require external high-quality energy input to achieve the purpose of enhanced heat transfer.

[0003] The use of fluid-induced vibration of heat transfer elements to achieve enhanced heat transfer is a form of passive enhanced heat transfer, which can transform the strict prevention of fluid vibration induction in the heat exchanger into the effective use of vibration, so that the transmission elements can operate at low flow rates The convective he...
