iquid water tower kettle cooler of finished off water tower kettle heat exchange equipment. Here uses utube heat exchanger, beacause one of kettle liquid dehydration tower coolers are used to achieve dehydration tower kettle liquid heat transfer equipment, Utube fixed at both ends of a tube with on the same tube plate, the bundle tubes can be freely scalable, does not produce thermal stress applied to high temperature and high pressure occasions, and easy to clean tube. The design of the main contents, including Utube heat exchanger technology process, the strength calculation, the structure of heat exchanger design and manufacture, testing and acceptance, installation, missioning and maintenance.Keywords: condenser, process calculation, structural design, strength calculation目
