Aluminum plate bar heat exchangers are usually composed of partitions, fins, seals, and guide fins. Fins, deflectors and seals are placed between two adjacent partitions to form an interlayer, which is called a channel. Such interlayers are stacked according to different fluid methods and brazed into a whole to form a plate bundle. The plate bundle is a plate. The core of the finned heat exchanger. Aluminum plate bar heat exchangers have been widely used in petroleum, chemical, natural gas processing and other industries.
