Analysis of heat transfer characteristics of induced vibration of elastic tube beam of heat exchanger

Abstract

Elastic tube bundle heat exchanger uses fluid induced elastic tube bundle vibration to achieve passive enhanced heat transfer. Due to the structural characteristics of traditional flat elastic tube bundle, the heat exchange area per unit volume in the heat exchanger is small and the comprehensive heat transfer performance is low, which makes the overall efficiency of the heat exchanger poor. Based on the design concept of fluid-induced vibration to enhance heat transfer and the structural characteristics of traditional shell and tube heat exchangers, a spiral elastic tube heat exchanger is proposed to make it efficient, reliable and flexible, taking miniaturization, lightweight and compact as the basic design criteria.
