This type of heat exchanger has the characteristics of a simple structure, compact, high reliability and wide adaptability , and low cost of the production, wide choice of used materials, more convenient of cleaning heat exchanger the surface. Synthesis of acetylene industry. The charge of cooling is important link in the process which makes cooler be the necessary equipment in this industry.  Heat exchanger is the realization of heat exchange and transfer during the process of chemical production indispensable equipment.In petroleum,chemical industry,light industry,pharmaceuticals,energy and other industrial production,often needs the fluid heating at low temperature or the high temperature cooling fluid,the liquid turns into vapor or steam condense into liquid. These processes and heat transfer are closely linked, and therefore can be through the heat exchanger to complete. This topic design is the use of related knowledge, designed to reach the required process requirements, at the same time, strength, reliable structure, easy to manufacture, installation and maintenance, as well as the floati
