[0002] Plate-fin heat exchangers are usually composed of baffles, fins, seals, and guide vanes. Fins, guide vanes, and seals are placed between two adjacent baffles 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. The plate bundle is the core of the plate-fin heat exchanger. Plate-fin heat exchangers have been widely used in industries such as petroleum, chemical industry, and natural gas processing.

[0003] However, in the prior art, conventional natural gas plate-fin heat exchangers are usually fixed to the equipment with bolts, and the installation steps are relatively complicated, which makes maintenance and replacement inconvenient. The bolts are easily lost after being removed. In addition, the sizes of natural gas plate-fin heat exchangers are different, and a fin heat exchanger that is too high is prone to tilting, which poses certain safety hazards and brings unnecessary trouble to users.
