Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, and in particular to a fin of a heat exchanger which is convenient for replacing the fin. Background Art

[0002] Heat exchanger is an energy-saving device that realizes heat transfer between two or more fluids at different temperatures. It transfers heat from a higher temperature fluid to a lower temperature fluid, so that the fluid temperature reaches the specified index of the process to meet the needs of process conditions. It is also one of the main equipment for improving energy utilization, also known as heat exchanger. Heat exchanger occupies an important position in chemical, petroleum, power, food and many other industrial production. In chemical production, heat exchanger can be used as heater, cooler, condenser, evaporator and reboiler, etc., and is widely used.

[0003] The patent specification with announcement number CN117213273A discloses a fin structure of a heat exchanger that is easy to replace fins. The liquid inlet pipe and the liquid outlet pipe are driven to move left and right along the heat exchange box by a movable plate. The movable plate drives the elastic part to expand and contract by cooperating with the sealing plate. The elastic part controls the expansion of the fin body by driving the mounting plate to move left and right. The liquid inlet pipe penetrates into the connecting pipe and squeezes the sealing block downward. The hot fluid flows into the heat exchange tube. The heat exchange tube exchanges heat with the hot fluid by cooperating with the fin body. The heat exchange tube and the fin body are adjusted according to specific usage requirements, so that the heat exchanger is suitable for heat exchange of hot fluids with different flow rates, and the use and heat exchange efficiency of the heat exchanger are higher.

[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: during the use of the above device, the fins of the heat exchanger are a fixed whole. When a single fin of the heat exchanger is damaged, if the single fin cannot be replaced, it will affect the normal operation of the heat exchanger, and the entire heat exchanger needs to be replaced, resulting in a waste of resources. Therefore, further improvement is needed. Utility Model Content
