The design of the column tube cooler
Abstract：Over the past 20 years, the heat exchange equipment has been widely used in energy storage，transform，recycle，new energy utilization，and the pollution control。And it`s a general equipment in many industry，like chemical industry, oil refining, food, light industry, energy, medicine, machinery and many others。In chemical industry，Heat transfer equipment investment by 10% to 20% of the total investment；In oil refining，it`s 35% to 40%. Besides, it`s also an effective device when recycling waste heat, Especially in the low grade heat energy. Improving the overall utilization of heat energy, Reducing the fuel consumption and power consumption and improve the economic benefits of industrial production.
This article is according to the title of Shell and tube heat exchanger to take a rational selection and make design. Content includes heat exchanger type selection, thermodynamic calculation, structural design, intensity, etc., the design of a variety of qualitative and quantitative factors, and their mutual influence and mutual dependency are discussed ,so that to optimizing the heat exchanger design.
Key words：Heat exchanger; Shell and tube cooler; Fixed tube plate; Thermodynamic calculation
