摘要
A method and apparatus are described for cleaning the inside of a heat exchanger tube while the tube is in operation and for simultaneously enhancing the heat transfer rate across the tube wall. The method consists of positioning a rod containing a tube cleaner inside of the heat exchanger tube and moving the rod in a back and forth motion during operation of the heat exchanger tube. The tube cleaner is designed to scrape the inside wall of the heat exchanger tube and to create turbulence in the fluid near the tube wall thereby improving the heat transfer rate across the tube wall.
