Analysis on Optimal Design Scheme of Shell and Tube Heat Exchanger with Given Heat Transfer Temperature Difference

Abstract

In industrial production and processing, the use of heat exchange equipment can realize the heat transfer between materials and achieve the goal of energy saving. At present, heat exchange equipment is used in many industrial production fields. In recent years, in China’s social production and life, the awareness of energy conservation and environmental protection has been continuously strengthened, which has also promoted the development and application of relevant energy-saving technologies. Relevant heat exchange equipment can effectively recycle high-temperature and low-temperature heat energy, with remarkable economic benefits. Shell and tube heat exchanger is the most widely used of all kinds of heat exchangers at present. This kind of heat exchanger has simple structure, good stability, wide practicability, low cost, convenient cleaning of heat exchange surface, and can meet the working environment of high strength and temperature. However, in the design of shell and tube heat exchanger, given the heat transfer temperature difference, some problems are easy to appear in the design of heat exchanger. Therefore, it is necessary to try to solve the problems through the idea of optimal design and improve the utilization efficiency of heat exchanger.
