A heat exchanger is a device that transfers part of the heat from a hot fluid to a cold fluid, and is an indispensable equipment for heat exchange and transfer in chemical production processes. There are many types of heat exchangers, which can be basically divided into partitioned, mixed, and regenerative types according to the principle and method of heat exchange between cold and hot fluids. The extensive use of heat exchangers has effectively improved energy utilization efficiency, reduced enterprise costs, and increased benefits
Heat exchangers are widely used in daily life, such as radiators for heating, condensers in steam turbine devices, and oil coolers on space rockets. They are also extensively applied in industrial sectors like chemical, petroleum, power, and atomic energy. Their primary function is to ensure the specific temperature required by the process for the medium, and they are also one of the main devices for improving energy utilization efficiency
