Heat exchanger is an important equipment of power, petroleum, chemical, steel, power, food and many other industrial sectors, plays an important role in the production. The research and design of this subject is using the feature of heat exchanger to transfer heat to the cold fluid and allowing the fluid temperature reaching to the process specified index, designing a suitable U shaped tube heat exchanger by using physical properties of materials through the heat exchanger to transfer heat between process materials.The characteristic of U shaped tube heat exchanger is that each of the tubes are bent into U shape, the fluid inlet and outlet are arranged on the same end of both sides,the partition in the head is pided into two rooms,and each of the tubes can be freely telescopic to solve the problem of thermal compensation. First, analysis and research of the process materials heat exchanger, and then argument the components of the structure of the design, then has carried on the structural design, calculation and verification. Finally draw the feed mechanism assembly and the main parts.
