Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a fin structure of a heat exchanger. Background Art

[0002] Heat exchangers are devices that transfer part of the heat of hot fluid to cold fluid, also known as heat exchangers. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial production. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used.

[0003] Existing plate-fin heat exchangers are usually composed of partitions, fins, seals, and guide vanes. Fins, guide vanes, and seals are placed between two adjacent partitions to form a sandwich, called a channel. Such sandwiches are stacked up according to different fluids and brazed into a whole to form a plate bundle, which is the core of the plate-fin heat exchanger. After long-term use, the fins are prone to failure, which affects the working efficiency of the heat exchanger. Therefore, it is necessary to regularly inspect and repair them. However, when removing the fins of the existing heat exchanger, the internal structure of the heat exchanger needs to be disassembled before the fins can be taken out, which greatly affects the inspection efficiency. Therefore, a heat exchanger fin structure that is easy to disassemble and inspect is needed. Utility Model Content
