Description

Technical Field

[0001] The utility model relates to the technical field of plate-fin heat exchangers, in particular to a plate-fin special-shaped aluminum seal strip. Background Art

[0002] Plate-fin heat exchanger is a highly efficient heat exchange equipment with compact structure and high heat transfer efficiency. It is widely used in many fields such as petroleum, chemical industry, natural gas processing, refrigeration, aerospace, etc. Plate-fin heat exchanger is usually composed of baffles, fins, seals, guide vanes, etc. Fins, guide vanes and seals are placed between two adjacent baffles to form a sandwich, which is called a channel.

[0003] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the seals used in plate-fin heat exchangers are mostly aluminum seals, which need to be fixed on both sides of the fins during installation. Since most aluminum seals are solid aluminum bars and lack the ability to be quickly replaced, traditional aluminum seals will have low heat transfer efficiency and inconvenient replacement operations when used. Therefore, a plate-fin special-shaped aluminum seal is proposed to address the above problems. Utility Model Content
