[0002] With the acceleration of my country's industrialization and urbanization, and the economic growth of developing countries worldwide, the demand for heat exchangers in both domestic and export markets will continue to grow. Heat exchangers are a widely used general-purpose device in many industrial sectors, including chemical, oil refining, power, food, light industry, nuclear energy, pharmaceuticals, machinery, and others. They play a vital role in production. In chemical production, heat exchangers can function as heaters, coolers, condensers, evaporators, and reboilers. A heat exchanger is a device used to transfer heat from a hot fluid to a cold fluid to meet specified process requirements. It is an industrial application of convective heat transfer and heat conduction. Shell-and-tube heat exchangers are currently the most widely used heat exchange equipment.

[0003] When disassembling the cooling shells at both ends of the heat exchanger, one worker needs to disassemble the connectors while two other workers support the cooling shells at both ends to prevent them from falling and being damaged. The disassembly process requires the cooperation of multiple workers, which is time-consuming and labor-intensive, and not convenient for a single person to operate.

[0004] Therefore, a microchannel enhanced heat transfer heat exchanger for propane dehydrogenation process is needed to improve the above problems. Utility Model Content
